Description

  The present invention relates to a recording apparatus including a movable stacker that receives a medium (paper or the like) discharged after recording, and a panel such as a movable operation panel provided in a housing.

  For example, in Patent Document 1, a movable stacker that receives a medium (such as paper) discharged after recording and a movable operation panel (an example of a panel) provided on a main body (an example of a housing) are common. Discloses a recording apparatus that operates in conjunction with the power of a single motor, which is a power source. The stacker is provided at the lower part of the front surface of the main body so that it can be withdrawn and retracted. When the power is turned on, the stacker slides outward from the main body and protrudes to a predetermined open position. On the other hand, the operation panel is provided so as to be rotatable around the front upper end of the main body. When the operation panel is closed, the lower end portion thereof is positioned on the movement path of the stacker. In this way, the movement path between the operation panel and the stacker partially overlaps, so that the recording apparatus can be downsized in the height direction.

  When the power is turned on, the stacker and the operation panel are operated to open from the closed position to the open position in conjunction with the power of the motor, so that they do not collide during the opening operation. When the operation panel is disposed at the open position, power transmission with the motor is interrupted, and the operation panel is configured to be manually closed by the user. Therefore, the stacker is unnecessary except during printing, and is closed by the power of the motor so as not to get in the way. However, the operation panel can be used by the user for other purposes other than printing, such as setting operation.

JP2013-209190A

  However, in the recording apparatus described in Patent Document 1, since the stacker protrudes with the opening operation of the operation panel when the power is turned on, and the stacker closes after the protrusion, the operation in which the stacker protrudes and retracts immediately is useless operation Met. In order to eliminate this useless operation, it is necessary to operate the panel and the stacker with independent power sources.

  However, in the configuration in which the movement path between the panel and the stacker partially overlaps as in the recording device described in Patent Document 1, when the operation panel and the stacker are driven independently, they collide with each other. I was worried. Note that the above-described problem is not limited to the operation panel, and the same applies even if the panel is a cover panel such as a movable cover.

  An object of the present invention is to provide a recording apparatus that can reduce the frequency of occurrence of collision between a panel and a stacker.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
A recording apparatus that solves the above problems includes a panel that can be opened and closed with respect to a housing of the recording apparatus, a movable stacker that can be moved with respect to the housing, and a first that drives the panel. A motor, a second motor for driving the stacker, and a control unit for controlling the first motor and the second motor, and a movement path for opening and closing the panel and a movement path for moving the stacker out When the overlapping instruction is received, the control unit closes the stacker and starts the closing operation of the panel after the stacker reaches a predetermined position during the closing operation.

  According to this configuration, when receiving the close instruction, the control unit closes the stacker and starts the panel closing operation after the stacker reaches a predetermined position during the closing operation. Therefore, when the control unit closes the stacker and the panel, the frequency of occurrence of collision between the two can be reduced.

  The recording apparatus further includes a first position detecting unit that detects the position of the panel and a second position detecting unit that detects the position of the stacker, and the control unit receives the closing instruction, When the panel is positioned closer to the retracted position than avoiding interference with the stacker, it is preferable that the panel is once opened to the retracted position and the closing operation is started from the retracted position.

  According to this configuration, when the control unit receives the close instruction, if the panel is located closer to the retracted position than the retractable position where the interference with the stacker can be avoided, the control unit temporarily opens the panel to the retracted position, A passage is secured. After the timing when the stacker reaches a predetermined position and the two do not interfere with each other, the panel starts to close from the retracted position. Therefore, the panel and the stacker can be closed while avoiding the collision between the two.

In the recording apparatus, it is preferable that the retracted position is a fully opened position of the panel.
According to this configuration, the panel is retracted to the fully open position, so that the stacker passage can be reliably secured. In addition, a sensor that detects the fully open position may be used as long as it is in the fully open position, but the panel can be stopped at the retracted position by hitting the end of the fully open position, for example, without using a sensor.

  In the recording apparatus, the first position detection unit is a first sensor that detects an open position of the panel, and the retracted position is changed from a state in which the first sensor indicates closing of the panel to a state in which opening is performed. It is preferable that the position is changed.

  According to this configuration, when the panel is opened from the closed position, the control unit opens the panel to a position where the first sensor changes from the closed state to the open state. Further, when the panel and the stacker are closed, the first sensor is used to retreat to a position where the first sensor has changed from a state representing closing of the panel to a state representing opening. Therefore, the control for opening the panel and the control for closing the panel can be performed using the common first sensor. For this reason, the number of parts can be reduced.

  In the recording apparatus, when the control unit starts the closing operation of the panel after the stacker reaches a predetermined position, the movement path of the panel and the movement path of the stacker partially overlap each other. In the region, it is preferable that the adjustment is performed at a timing at which the panel moves in the closing direction after the stacker first moves in the closing direction.

  According to this configuration, in the interference region where the movement path of the panel and the movement path of the stacker partially overlap, after the stacker moves first in the closing direction, the panel moves in the closing direction. Therefore, the panel and the stacker can be closed while avoiding a collision. For example, the panel can be closed to the housing side while the stacker is housed in the housing. For example, if the timing of passing through the interference area between the panel and the stacker is reversed, the panel closed first on the housing side becomes an obstacle and the stacker cannot be stored in the housing.

  The recording apparatus includes: a first position management unit that manages a position of the panel in the movable range; and a second position management unit that manages a position of the stacker in the movable range, and the control unit includes the closing instruction. From the position of the panel and the position of the stacker when the panel is received, the panel and the stacker obtain a waiting time of the panel that does not interfere in the process of closing, and after starting the closing operation of the stacker, It is preferable to wait for the waiting time before starting the closing operation of the panel.

  According to this configuration, the control unit obtains the standby time of the panel from which the panel and the stacker do not interfere during the closing operation from the panel position and the stacker position when the close instruction is received, and closes the stacker. After starting the operation, the panel closing operation is started after waiting for the waiting time. For this reason, the closing operation of both can be started from the position of the panel and the position of the stacker when the closing instruction is received.

  In the recording apparatus, the second position detection unit is a second sensor that detects that the stacker being opened has reached the open position, and the control unit closes both the panel and the stacker. Preferably, after the second sensor changes from the open state to the close state, the panel closing operation is started after a predetermined time.

  According to this configuration, when the stacker is opened from the closed position, the stacker is opened by causing the control unit to open the stacker to a position where the second sensor changes from the closed state to the open state. When the panel and stacker are closed, the second sensor is used to wait for a predetermined time after the second sensor changes from the state indicating the opening of the panel to the state indicating the closing. Be started. Therefore, it can be closed while avoiding the collision between the panel and the stacker. Therefore, the control for opening the stacker and the control for closing the stacker can be performed using the common second sensor. For this reason, the number of parts can be reduced.

  In the recording apparatus, it is preferable that the control unit causes the panel to be closed without waiting at the retracted position when the stacker is positioned closer to the closed position than the predetermined position.

  According to this configuration, when the stacker is positioned closer to the closing position than the predetermined position, the panel is closed without waiting at the retracted position. For this reason, the panel can be closed without wasteful waiting.

  In the recording apparatus, when the control unit receives the closing instruction, if the stacker is in a position closer to the closing side than a predetermined position, the panel is closer to the closing side than the retracted position. If the movement path of the panel and the movement path of the stacker are not in an interference region that partially overlaps, it is preferable that the panel is closed without being moved to the retracted position.

  According to this configuration, when the stacker is positioned closer to the closing position than the predetermined position, even if the panel is closer to the closing position than the retracting position, if the stacker is not in the interference region, the closing operation is performed without moving to the retracting position. .

(First embodiment)
Hereinafter, a first embodiment in which a recording apparatus is embodied in a printer will be described with reference to the drawings.
As shown in FIG. 1, the printer 11 includes an apparatus main body 12 (hereinafter, also simply referred to as “main body 12”) as an example of a thin housing having a substantially rectangular parallelepiped shape, and a front surface of the main body 12 (right surface in FIG. 1). And an operation panel 13 used for user input operations. The operation panel 13 is a rotation type attached so as to be rotatable about the upper end. The operation panel 13 includes a display unit 14 made of a liquid crystal panel or the like and an operation unit 15 made up of a plurality of operation switches. The operation unit 15 includes a power switch 15a for turning the printer 11 on and off, and an operation switch 15b for selecting and operating a desired item on the menu screen displayed on the display unit 14. It is.

  As shown in FIG. 1, a feeding cassette 16 capable of accommodating a plurality of sheets P as an example of a medium is inserted in a lower portion of the main body 12 in a state where the feeding cassette 16 can be inserted and removed. A plurality of sheets P accommodated in the feeding cassette 16 are sent out one by one in order from the top by a pickup roller 17 (see FIG. 3), and the delivered sheets P are conveyed along a predetermined conveyance path. It is conveyed in the direction Y.

  A carriage 18 is provided in the main body 12 so as to be reciprocally movable in the scanning direction X while being guided by a guide shaft 19 extending along the scanning direction X intersecting the transport direction Y. A recording head 20 that ejects ink droplets from nozzles is attached to the lower portion of the carriage 18. Printing is performed on the sheet Pd by ejecting ink droplets from the recording head 20 that reciprocally moves with the carriage 18 in the scanning direction X toward the surface of the sheet Pd that is intermittently conveyed in the conveying direction. The printed paper Pd is discharged in the direction indicated by the white arrow in FIG. 1 from the discharge port exposed when the rotary cover 21 disposed below the operation panel 13 is opened. The printer 11 can also perform printing by manually inserting the paper P from an insertion port that is exposed when the openable cover 22 provided at the rear of the main body 12 is opened.

  As shown in FIG. 2, the operation panel 13 is a movable type that opens and closes by rotating around the front upper end of the main body 12, and is between a closed position shown in FIG. 1 and an open position shown in FIG. 2. It is rotated electrically. Further, as shown in FIG. 2, the main body 12 is provided with a stacker 23 (medium receiving portion) constituted by a substantially square plate-like tray in a state in which the stacker 23 can move in and out. The stacker 23 is electrically operated and has a closed position (retracted position) (for example, the state shown in FIG. 1) housed in the main body 12 and an open position (for example, the state shown in FIG. 2) protruding from the main body 12 by a predetermined amount. It can move back and forth between them. The operation panel 13 and the stacker 23 are driven by separate power sources. For example, when the power is turned on, the operation panel 13 is rotated forward from the closed position shown in FIG. 1 and arranged at an open position with a predetermined posture angle that is easy for the user to see as shown in FIG. This open position is, for example, about 45 degrees when the attitude angle when the operation panel 13 is in the closed position shown in FIG. The posture angle of the panel 13 in the open position is not limited to 45 degrees, and may be any other posture angle between the closed position (0 degrees) and the fully open position, and an angle in the range of 30 to 70 degrees is particularly preferable.

  Further, the stacker 23 protrudes from the main body 12 when printing is performed such as when a print job is received. The cover 21 is opened by being pushed by the protruding stacker 23. Then, when the stacker 23 reaches the open position slightly before the fully open position, it decelerates and stops. For this reason, the stacker 23 is in an open state that is located in a range (open region) from the open position to the fully open position. The printed paper Pd is discharged onto the stacker 23 in the open state. When printing is finished, the stacker 23 is housed in the main body 12 and placed in the closed position. Even if the stacker 23 is retracted from the open state to the closed position, the operation panel 13 is held in the open state.

  When the power is turned off, the operation panel 13 and the stacker 23 in the open state shown in FIG. That is, the closing operation from the open state of the operation panel 13 and the closing operation from the open state of the stacker 23 are performed at the same time. In addition, an instruction button (icon button) that can instruct an opening operation or a closing operation of the stacker 23 is displayed on the display unit 14. If the display unit 14 is a touch panel, the instruction button can be directly pressed, and if not, the instruction button can be selected and operated by operating the operation switch 15b to instruct the opening and closing operations of the stacker 23. The instruction button may be provided with an open button and a close button separately, or may be configured as a single button that is a closed button when the stacker 23 is open and an open button when the stacker 23 is closed. Good.

  In the printer 11 according to the present embodiment, a route when the operation panel 13 rotates and a route when the stacker 23 moves out and overlap partially. For this reason, there is a possibility that the operation panel 13 and the stacker 23 may collide with each other in the overlapping part of the path (hereinafter also referred to as “interference area”) depending on the position and timing of opening and closing. For example, if the closing operation of the stacker 23 and the closing operation of the operation panel 13 are performed at the same time, the operation panel 13 closes earlier, so that they collide. For this reason, in the present embodiment, when the operation panel 13 and the stacker 23 are both opened or closed together, the control for adjusting the operation timing of both is employed. Details of this control will be described later. In the following description, the operation panel 13 may be simply referred to as “panel 13”.

Next, a detailed configuration of the printer 11 will be described.
Hereinafter, the components on the paper transport path will be described with reference to FIG. As shown in FIG. 3, a cassette feeding unit 25, a feeding unit 26, a medium conveying unit 27, a recording unit 28, and a feeding unit 29 are provided in the main body 12 along the path through which the sheet is fed and conveyed. Is provided. The cassette feeding unit 25 includes a feeding cassette 16, a pickup roller 17 provided above the feeding cassette 16, and a separation unit provided at a position facing the front end of the paper P stored in the feeding cassette 16. 30.

  The pickup roller 17 is provided at the tip of a swing member 32 that can swing around a swing shaft 31, and rotates by power transmitted from the transport motor 33 (see FIG. 6). The pickup roller 17 rotates in contact with the uppermost sheet P stored in the feeding cassette 16, thereby feeding the uppermost sheet P from the feeding cassette 16 to the feeding path. The uppermost sheet P to be fed is separated from the next and subsequent sheets P by the separating unit 30 during the feeding.

  As shown in FIG. 3, the feeding unit 26 provided on the downstream side of the feeding path of the separation unit 30 includes a feeding driving roller 34 driven by the conveyance motor 33, a pair of feeding driven rollers 35 and 36, and It has. The sheet P sandwiched between the feeding drive roller 34 and the feeding driven roller 36 is conveyed to the medium conveying unit 27 while the conveyance direction is changed along the outer periphery of the feeding driving roller 34. The medium transport unit 27 includes a transport driving roller 37 that is also driven by the transport motor 33, and a transport driven roller 38 that is driven to rotate in pressure contact with the transport driving roller 37. The medium P is sent further downstream by the medium transport unit 27.

  As shown in FIG. 3, the recording unit 28 provided on the downstream side of the medium conveying unit 27 includes a carriage 18, the recording head 20, and a support base 39 that faces the recording head 20. The recording head 20 provided at the bottom of the carriage 18 so as to face the conveyance path of the paper P is scanned in the scanning direction X (FIG. 3) while the carriage 18 is guided by the guide shaft 19 by the power of the carriage motor 40 (see FIG. 6). Then, in the process of reciprocating in the direction orthogonal to the paper surface, ink droplets are ejected onto the paper P to print an image on the paper P. At this time, the support base 39 supports the paper P and defines the distance (gap) between the paper P and the recording head 20.

  The feeding unit 29 provided on the downstream side of the support base 39 includes a first roller 41 driven by the transport motor 33 and a second roller 42 that rotates in contact with the first roller 41. The recorded paper P is sent out by the feeding unit 29 while being sandwiched between the first roller 41 and the second roller 42.

  The recorded paper P that has been sent out is projected from the closed position indicated by the solid line in FIG. 3 stored in the main body 12 to the front side when receiving a print job, and is disposed at the open position indicated by the two-dot chain line in FIG. 23 is discharged to the upper surface. The stacker 23 slides along the Y direction and protrudes to the outside (front) of the main body 12 (opening operation), and retracts (closes) that slides along the anti-Y direction and is stored in the main body 12. Operation). The stacker 23 slides out of the main body 12 and projects at least during printing.

  Further, the sheet P (shown by a two-dot chain line in FIG. 2) inserted manually from the feeding port 43 exposed with the cover 22 provided at the rear part (right side in FIG. 3) opened of the main body 12 is fed. It is inserted between the drive roller 34 and the feed driven roller 36 and is driven by the medium transport unit 27 and the feed unit 29 by driving the transport motor 33 in this state. In the present embodiment, the feeding unit 26, the medium transporting unit 27, and the feeding unit 29 constitute an example of the transporting unit.

  The stacker 23 is formed with an inclined guide surface 23a that is inclined so that the front end portion in the transport direction Y becomes higher toward the front end side, and a base portion 23b that bulges upward, and the width direction of the base portion 23b (same as the scanning direction X) ) A pair of raised portions 23c that are higher than the base portion 23b and are adjacent to both sides. Further, the stacker 23 has a base portion 23d excluding the tip portion formed in a square plate shape (see FIG. 6). Between the plate-like frame 44 arranged on the lower side of the support base 39 and the plate-like support plate portion 45 arranged on the lower side thereof with a predetermined interval therebetween, the stacker 23 An accommodation recess 46 capable of accommodating the base 23d is formed. The stacker 23 is placed in the closed position indicated by a solid line in FIG. 3 by inserting the base 23d deep into the receiving recess 46, and protrudes outward (forward) with respect to the main body 12 from the closed position. By moving, it is arranged at the open position (state shown in FIG. 2) indicated by a two-dot chain line in FIG. Here, the open position is the position of the stacker 23 in a protruding amount that allows the discharged printed paper P to be stacked on the stacker 23.

  In the printer 11 of the present embodiment, when the power is turned on, first, only the panel 13 is opened to the open position indicated by a two-dot chain line in FIG. Thereafter, the stacker 23 performs a protruding operation when a print job is received. Thus, since the panel 13 is first opened and the movement path of the stacker 23 is ensured, the stacker 23 is operated to project, so that they do not collide.

  The printer 11 according to the present embodiment has a label printing function for printing on the label surface of a disk such as a CDR or a DVD. A pair of guide grooves 24 (both in the scanning direction X) on both sides in the width direction (same as the scanning direction X) on which a disc (not shown) can be slid and inserted on both sides in the width direction at the tip of the stacker 23 shown in FIG. Only one of them is shown in FIG. By inserting the tray horizontally along the guide groove 24, the tray is placed on the rollers 37 and 41 and inserted in a state of being nipped between the pair of rollers 37 and 38 on the back side. The unit that supports the roller 42 is slightly raised to a height at which the roller 42 is separated from the tray by engaging with the inserted tray. In this way, by using the same rollers 37, 38, and 41 as when printing on the paper P, printing is performed by the recording head 20 on the label surface of the disc set on the tray being transported. .

  A tray sensor 48 (see FIG. 7) that detects a tray inserted along the guide groove 24 during label printing is provided in the main body 12. The tray sensor 48 detects that the tray has been taken out along the guide groove 24 after the label printing is completed.

  Further, as shown in FIG. 3, in this printer 11, the panel 13 when in the closed position is positioned on the movement path when the stacker 23 moves from the closed position to the open position, and such a layout is adopted. Thus, the main body 12 is thinned while ensuring a wide width in the height direction of the panel 13. As described above, the printer 11 has a structure in which the area where the stacker 23 slides and moves out and the area where the panel 13 rotates interfere with each other.

  As shown in FIG. 1, when the icon button is operated in a state where the panel 13 and the stacker 23 are both closed, the panel 13 and the stacker 23 start opening simultaneously. Also in this case, the panel 13 and the stacker 23 do not collide.

  As shown in FIG. 2, in order to receive the printed paper P, the stacker 23 needs to secure a predetermined output amount. Further, the panel 13 is disposed at a posture angle of about 45 degrees that is easy for the user to see. When the panel 13 and the stacker 23 are closed from this open state, even if the start of the closing operation is the same, the panel 13 closes earlier and the stacker 23 closes later. At this timing, the raised portion 23c collides with the lower end of the panel 13 before the stacker 23 is completely closed, and the stacker 23 is not completely closed.

  Further, since the panel 13 and the stacker 23 can be manually moved by the user, the attitude angle of the panel 13 and the protruding amount of the stacker 23 when starting the closing operation are not determined. For this reason, for example, when the panel 13 has already been manually closed or is in a close attitude angle of about 10 to 30 degrees, the raised portion 23c is formed at the lower end of the panel 13 when the stacker 23 is closed. Collide with the part. Therefore, in the present embodiment, when the panel 13 and the stacker 23 are closed, the control is performed such that the respective operation start timings are adjusted and the two do not collide.

Next, the configuration of the panel 13 will be described with reference to FIG.
The panel 13 has a pair of rotating shafts 13a (not shown in FIG. 4) that protrude from the upper ends of both side portions by the power transmitted from the first motor 50 (electric motor) serving as the power source via the power transmission mechanism 51. It pivots between a closed position and an open position centered on one side only). In the present embodiment, when the first motor 50 is driven forward, the panel 13 is opened in the direction from the closed position toward the open position, and when the first motor 50 is driven reversely, the panel 13 is opened. Closes in the direction from to the close position.

  The power transmission mechanism 51 is fitted to a small-diameter gear 53 that meshes with a pinion 52 that is fitted to the drive shaft 50a of the first motor 50, and the other end of the rotary shaft 54 that is fitted to one end. The same gear 55 having a small diameter and a large gear 56 meshing with the gear 55 are provided. Further, the gear 56 meshes with the gear 57 a of the friction clutch 57, and the rotation of the gear 57 a is transmitted to the two two-stage gears 58, 59 arranged coaxially, and the small-diameter portion 59 a of the two-stage gear 59 is transferred to the gear 60. Is engaged. A cylindrical gear 61 that meshes with the gear 60 meshes with a sector gear 65 formed on the upper end side of the panel 13.

  The friction clutch 57 is provided in a state where a fixing portion 57b fixed to the main body 12 and a gear 57a are pressed by a coil spring (not shown). Therefore, while the first motor 50 is being driven, the gear 57a rotates relative to the fixed portion 57b, and the rotation is transmitted to the sector gear 65 via the gears 58 to 61, whereby the panel 13 rotates. . While the first motor 50 is stopped, the panel 13 is maintained in the posture at that time by the frictional force between the gear 57a and the fixed portion 57b. The gear 56 is a two-stage gear, and a two-stage gear 64 having substantially the same diameter is provided coaxially next to the gear 56.

  The first motor 50 is provided with an encoder 62 that outputs a detection pulse signal having a number of pulses proportional to the rotation amount. A first sensor 63 (panel open sensor) that detects a state in which the panel 13 is in the open position is disposed on the back side of the panel 13. The first sensor 63 is configured by an optical sensor that can detect the plate-like detected portion 13 b extending from the back surface of the panel 13. When the panel 13 is at the posture angle of the open position, the detected portion 13b can be inserted into the recess through which the detection light of the first sensor 63 passes. If the posture angle at which the panel 13 is parallel to the front surface of the main body 12 is 0 degree and the opening direction is a plus direction, the panel 13 opens and closes in the range of 0 to 90 degrees.

  As shown in FIG. 5, when the panel 13 is opened to a predetermined angle θ1 when the panel 13 is in the open position, the detection unit 63b of the first sensor 63 detects the detection unit 13b from the non-detection state where the detection unit 13b is not detected. Switch to the detection state. That is, the detection state of the first sensor 63 is switched from a state representing close to a state representing open. For example, θ1 is a predetermined angle within a range of 30 to 70 degrees (about 45 degrees as an example). In the present embodiment, the predetermined angle θ1 is set as the origin for the closing control performed when the panel 13 is closed. The first sensor 63 may be a contact sensor instead of a non-contact sensor such as an optical sensor.

  Here, the reason why the detection switching angle of the first sensor 63 is set to θ1 degrees is as follows. For example, when θ1 is set to 0 degree, the panel 13 must be moved to the closed position (0 degree) for obtaining the origin. For example, if the stacker 23 is in a protruding state at that time, the panel 13 is placed on the stacker 23. There is a concern of hitting the printed paper P. On the other hand, if θ1 is set to 90 degrees, for example, the panel 13 is once moved to the fully open position when the power is turned on, the origin is set, and then returned to the target position from the fully open position. The time required until 13 is arranged at the target position becomes longer.

  For this reason, in the present embodiment, the switching angle of detection of the first sensor 63 is set to θ1, so that the panel 13 does not hit the printed paper P on the stacker 23 and closes to θ1 even if it is closed to θ1. However, it takes less time than the case of opening up to the maximum angle (90 degrees as an example), and it is possible to move the panel 13 to the target position by finishing the origin point early.

  Next, the configuration of the stacker 23 will be described with reference to FIG. The stacker 23 includes a medium receiving surface 23e on the upper surface of the base portion 23d. A pair of racks 69, 69 extending from the upstream side to the downstream side in the protruding direction (same as the transport direction Y) are provided at both ends of the medium receiving surface 23e in the paper width direction. The racks 69 and 69 are fitted at respective positions spaced apart by a predetermined distance in the axial direction of the rotary shaft 72 constituting the power transmission mechanism 71 to which the power of the second motor 70 that is the power source of the stacker 23 is transmitted. The pair of pinion gears 73 and 73 mesh with each other.

  The stacker 23 moves between the closed position and the open position by the power transmitted from the second motor 70 via the power transmission mechanism 71. In the present embodiment, when the second motor 70 is driven forward, the stacker 23 moves in the protruding direction from the closed position toward the open position, and when the second motor 70 is driven reversely, the stacker 23 is moved from the open position. Move in the retreat direction toward the closed position.

  Further, a second sensor 74 (stacker open sensor) that detects a state in which the stacker 23 is in the open position is provided in the main body 12. The second sensor 74 detects the notch recess 23f formed in the rear end portion of the stacker 23 when the stacker 23 is in the open state located in the range from the open position to the fully open position. For this reason, the second sensor 74 is switched from a state representing opening at the open position in the middle of the stacker 23 projecting to a state representing opening, and represents the closing from the state representing the opening in the middle position where the stacker 23 is retracted. Switch to state. Here, the open position of the stacker 23 is, for example, a position set within a range of 70 to 95%, for example, when the fully open position is 100% with the fully closed position of the stacker as a reference (0%). The open position can be set to an appropriate value within the range of 50 to 100%, for example.

  The second sensor 74 is a switch type sensor that changes from a state indicating closing of the stacker 23 to a state indicating opening at the open position when the stacker 23 performs an opening operation that protrudes outward (open side) from the closed state. . The second sensor 74 is configured by, for example, an optical non-contact sensor, but a contact sensor such as a limit switch can also be used. The second motor 70 is provided with an encoder 75 that outputs a detection pulse signal having a number of pulses proportional to the rotation amount.

  Moreover, as shown in FIG. 6, the recessed part 23g is formed in the center part of the width direction in the protrusion direction upstream (base in FIG. 6) part of the base 23d. The stacker 23 is accommodated in the closed position while avoiding the swinging member 32 (see FIG. 3) supporting the pickup roller 17 by the recess 23g. For this reason, the stacker 23 can be inserted to a deep position in the main body 12 in the closed position. Therefore, although the stacker 23 has a single tray structure, a necessary amount of protrusion is ensured when protruding from the main body 12.

  As shown in FIG. 6, the rotation of the pinion 76 fitted to the drive shaft of the electric motor 70 is transmitted to the gear 78 via the gear 77. A gear train 79 including gears 79 a to 79 g arranged in a state where the rotation of the gear 78 can be transmitted to the lower side of the gear 78 is a power transmission path to the stacker 23. A gear 79 g located at the final stage on the power transmission path in the gear train 79 is fitted to one end of the rotating shaft 72. The rotation of the rotating shaft 72 due to the rotation of the gear 79g causes the pair of pinion gears 73 and 73 to rotate, and the stacker 23 slides in a direction parallel to the transport direction Y through a pair of racks 69 meshing with the pinion gears 73 and 73. It has become. A gear 79d in the gear train 79 constitutes a part of a friction clutch 79k having a friction clutch mechanism. When a rotational force exceeding a certain value is applied to the gear 79d, the power transmission surface slips and idles. By interposing the gear 79d constituting the friction clutch 79k, the user can slide the stacker 23 in the retracting direction with a relatively light force, and the gear meshing noise and the like are reduced. Further, even if the stacker 23 hits an obstacle, the friction clutch 79k does not slip and lock, so that an excessive load is not applied to the second motor 70.

  In the present embodiment, the controller 80 (see FIG. 7), which will be described later, is switched to the second state when the detection state of the second sensor 74 is switched from the closed state to the open state during the forward rotation of the second motor 70. The drive is stopped while the motor 70 is decelerated. For this reason, the stacker 23 stops at a position on the protruding side by a predetermined distance from the open position. That is, the stacker stops at a position in the open region between the open position and the fully open position.

Next, the electrical configuration of the printer 11 will be described with reference to FIG.
As shown in FIG. 7, the printer 11 includes a controller 80 that performs various controls. The controller 80 is communicably connected to the host device 200 via the communication interface 81. The controller 80 controls the printing operation of the printer 11 based on the print job data received from the host device 200. The host device 200 is made up of a personal computer, for example, and incorporates a printer driver 201. The host device 200 includes an input unit 202 including a keyboard and a mouse, and the user operates the input unit 202 so that a paper type, a paper size, and a print color are displayed on a setting screen displayed on the monitor (not shown) by the printer driver 201. And print condition information including print quality and the like are input and set. The printer driver 201 generates print image data of an image for which execution of printing is designated based on the print condition information, generates print job data by adding a header including a part of the print condition information to the print image data, This is transmitted to the printer 11.

  The controller 80 is electrically connected to the carriage motor 40, the transport motor 33, the first motor 50, the second motor 70, and the display unit 14 as an output system. Further, the controller 80 includes, as an input system, an operation unit 15 including a power switch 15a and an operation switch 15b, a linear encoder 82, encoders 49, 62, and 75, a first sensor 63 (panel open sensor), and a second sensor 74 ( A stacker open sensor) and a tray sensor 48 are electrically connected.

  As shown in FIG. 7, the controller 80 includes a computer 85, a head driver 86, motor drivers 87 to 90, and a display driver 91. The computer 85 drives the recording head 20 via the head driver 86 based on the print job data, and draws an image based on the print image data by ejecting ink droplets. Further, the computer 85 drives and controls the carriage motor 40 via the motor driver 87 and controls the movement of the carriage 18 in the scanning direction X. At this time, the computer 85 counts the input pulses from the linear encoder 82 with a counter (not shown), thereby grasping the movement position of the carriage 18 with the home position as the origin, for example.

  Further, the computer 85 drives and controls the transport motor 33 via the motor driver 89. Here, the pickup roller 17 can be rotated by switching the power transmission switching unit 92 (clutch unit) interposed on the power transmission path of the transport motor 33 at the time of paper feeding. Further, the power of the transport motor 33 is transmitted, and the feeding drive roller 34, the transport drive roller 37, and the first roller 41 rotate. At this time, the computer 85 grasps the transport position of the paper P by counting the input pulses from the encoder 49 with a counter (not shown).

  A plurality of sheets P accommodated in the feeding cassette 16 are sent out one by one in order from the top by the pickup roller 17, and the fed sheets P are fed to the feeding driving roller 34, the conveyance driving roller 37, and the second one. 1 roller 41 is rotated along a predetermined path. Ink droplets are ejected from the recording head 20 that reciprocates in the scanning direction X together with the carriage 18 onto the surface of the paper P at a recording position in the middle of the transport path, and an image or document is printed on the surface of the paper P.

  Further, as shown in FIG. 7, the computer 85 drives and controls the first motor 50 via a motor driver 89. When the first motor 50 is driven in the forward direction, the panel 13 rotates in the opening direction, and when the first motor 50 is driven in the reverse direction, the panel 13 rotates in the closing direction.

  The first sensor 63 (panel open sensor) is turned on when the panel 13 is in the open region on the open side of the open position of about 45 degrees, and is turned off when the panel 13 is not in the open region. Further, the encoder 62 outputs a detection pulse signal having a number of pulses proportional to the rotation amount of the first motor 50 to the computer 85.

  Further, as shown in FIG. 7, the computer 85 drives and controls the second motor 70 via the motor driver 90. When the second motor 70 is driven to rotate in the forward direction, the pinion gear 73 rotates in the forward direction, and the stacker 23 moves in the protruding direction through the meshing of the forwardly rotating pinion gear 73 and the rack 69. On the other hand, when the second motor 70 is driven to rotate in the reverse direction, the pinion gear 73 rotates in the reverse direction, and the stacker 23 moves in the storing direction in the main body 12 through the meshing of the reversely rotating pinion gear 73 and the rack 69.

  The second sensor 74 (stacker open sensor) is turned on when the stacker 23 is in the open region on the protruding side from the open position, and is turned off when the stacker 23 is not in the open region. Further, the encoder 75 outputs a detection pulse signal having a number of pulses proportional to the rotation amount of the second motor 70 to the computer 85.

  7 includes, for example, a CPU 100, an ASIC 101 (Application Specific IC (IC)), a RAM 102, a nonvolatile memory 103, and the like. The nonvolatile memory 103 stores various programs including the stacker control program shown in the flowcharts of FIGS. 10 and 11. The computer 85 includes a plurality of functional units shown in FIG. 7 that are software configured by the CPU 100 executing a program stored in the nonvolatile memory 103. That is, the CPU 100 includes a main control unit 111, a detection unit 112, a determination unit 113, a timer 114, a first counter 115, and a second counter 116 as a plurality of functional units. Of course, the configuration is not limited to software using the computer 85, and may be a configuration of hardware such as an electronic circuit (for example, a custom IC) or a configuration based on cooperation between software and hardware.

  As shown in FIG. 7, the main control unit 111 controls the printer 11 in an integrated manner, and controls the operations of the printing system, the panel system, and the stacker system. The main control unit 111 controls the recording head 20, the carriage motor 40, and the conveyance motor 33 via the drivers 86 to 88 when controlling the printing system. The main control unit 111 controls the first motor 50 and the second motor 70 via the drivers 89 and 90 when controlling the panel system and the stacker system. When performing control of the panel system and the stacker system, the main control unit 111 detects the detection result of the detection unit 112, the determination result of the determination unit 113, the time measured by the timer 114, each of the first counter 115 and the second counter 116. Use the count value.

  The detection unit 112 detects an overload applied to each of the first motor 50 and the second motor 70. That is, the detection unit 112 detects an overload in which the load of the first motor 50 exceeds the threshold when the panel 13 hits the stacker 23 or the end of the movable range. The detection unit 112 detects an overload in which the load of the second motor 70 exceeds the threshold when the stacker 23 hits the panel 13 or the end of the movable range. The overload can be detected by using a detection method for overloading when the current values of the motors 50 and 70 exceed a threshold value. In addition, it is possible to use a detection method for overloading when the number of input pulses from the encoders 62 and 75 per unit time, that is, when the driving speed of the motors 50 and 70 is less than a threshold value. In addition, it is possible to use a detection method in which an overload occurs when the interval time between pulse edges from the encoders 62 and 75 exceeds a threshold value. In addition, other overload detection methods such as detecting the torque of the motors 50 and 70 may be used.

  The determination unit 113 performs various controls necessary for performing an open control for controlling at least one of the panel 13 and the stacker 23 and a close control for controlling at least one of the panel 13 and the stacker 23. The determination process is performed.

  In the open control and the close control in which the panel 13 and the stacker 23 are moved together, the timer 114 is imposed on one (panel 13 in this example) in order to avoid a collision in an interference region where the paths of the panel 13 and the stacker 23 overlap. The waiting time WT to be performed is counted.

  The first counter 115 counts the rotational position of the panel 13. In the present embodiment, the absolute position of the panel 13 is not particularly managed for the position control of the panel 13, and is used for grasping the position necessary when the speed of the first motor 50 is controlled. Note that the absolute position of the panel 13 may be managed by the count value of the first counter 115. For example, the first counter 115 receives the position from the encoder 62 from the position where the panel 13 hits the end and the overload is detected or the position of the panel 13 when the first sensor 63 detects that the panel 13 is in the open position. The pulse edges of the detection pulse signal are counted. Then, the value of the first counter 115 is incremented when the panel 13 is in the opening operation, while the value of the first counter 115 is decremented when the panel 13 is in the closing operation.

  The second counter 116 counts the position of the stacker 23. In the present embodiment, the absolute position of the stacker 23 is not particularly managed, and is used for grasping the position required when the speed of the second motor 70 is controlled. Since the slip is generated by the friction clutch 79k in the power transmission mechanism 51 of the stacker 23, even if the rotational position of the second motor 70 is managed, the actual position of the stacker 23 is shifted. For this reason, in this example, the absolute position within the movable range of the stacker 23 is not managed. The main control unit 111 outputs a command value corresponding to the value of the second counter 116 to the motor driver 90, so that the stacker 23 is moved from the movement start position to the stop position in accordance with the current position of the stacker 23. The speed of the second motor 70 is controlled to the determined speed. When the friction clutch 79k is eliminated, the absolute position of the stacker 23 may be managed by the second counter 116. In this case, the second counter 116 uses the position when the stacker 23 hits the end and detects an overload or the position when the second sensor 74 detects that the stacker 23 is in the open position as an origin. Then, the second counter 116 increments the number of pulse edges of the detection pulse signal from the encoder 75 when the stacker 23 opens and decrements when the stacker 23 closes.

  The computer 85 performs an open control for controlling the first motor 50 and the second motor 70 so that the panel 13 and the stacker 23 do not collide in the interference region in the process of performing the opening operation, and the panel 13 and the stacker 23 perform the closing operation. Close control for controlling the first motor 50 and the second motor 70 is performed so as not to collide in the interference region in the course of performing.

  The open control is performed when the user turns on the power, operates the open button, receives print data, and receives label printing. That is, when the printer 11 is off (when the power is off), the CPU 100 instructs to open the power on operation signal input from the power switch 15a, the open button operation signal input, the print data reception, or the label print acceptance. And accept open control.

  The close control is performed when the user turns off the power, when the close button is operated, when the print job ends, or when the stacker is pushed. In other words, the CPU 100 performs the closing control when the printer 11 is activated (when the power is on), when a power-off operation signal is input from the power switch 15a, when a close button operation signal is input, when a print job is completed, or when a stacker pressing operation is detected. Run. When the power off operation signal and the close button operation signal are input, both the panel 13 and the stacker 23 are closed. When the print job is completed and when the stacker pushing operation is detected, only the stacker 23 is closed. Panel 13 does not operate.

  Here, the detection of the stacker pressing operation refers to the detection of the user's pressing operation that triggers the stacker pressing assist control. In this embodiment, when the user pushes the stacker 23 lightly, the stacker push assist control is used to detect the push operation and automatically retract the stacker 23 to the fully closed position. When the computer 85 is not driving the second motor 70, the push operation of the stacker 23 by the user is detected when the second sensor 74 detects the switching from the state indicating the opening of the stacker 23 to the state indicating the closing. Is detected. When this stacker pushing operation is detected, the computer 85 performs stacker pushing assist control for rotating the second motor 70 in the reverse direction and closing the stacker 23 until reaching the fully closed position. Upon detecting the stacker pushing operation, the computer 85 starts the reverse rotation driving of the second motor 70, and the number of driving steps of the second motor 70 reaches a predetermined number of steps sufficient to reach the fully closed position, or the stacker 23 is closed. If an overload is detected by hitting the end on the side, the reverse rotation driving of the second motor 70 is stopped.

  Hereinafter, the open control will be described with reference to FIG. FIG. 8A shows open control when a power-on operation signal is input. When the power is turned on, the stacker 23 used for printing is not necessary yet, so only the panel 13 is rotated to the open position. At this time, the panel 13 does not collide with the stacker 23.

As shown in FIG. 8B, when the stacker 23 is in the open position, it does not collide with the panel 13, so that only the panel 13 is rotated to the open position.
As shown in FIG. 8C, when the raised portion 23c of the stacker 23 is positioned immediately before the panel 13, when the panel 13 is rotated toward the open position, the lower end portion thereof becomes the raised portion 23c. collide. The panel 13 stops in a state of colliding with the stacker 23 at the position of the two-dot chain line in FIG. In this case, a large overload is applied to the first motor 50 that attempts to move the panel 13 to the open side. In the present embodiment, when the first motor 50 is overloaded with a load exceeding a threshold value, the rotation operation of the panel 13 is stopped. Then, an error message is displayed on the display unit 14 to urge manual operation of the panel 13, for example.

  Then, from this state, the panel 13 and the stacker 23 are simultaneously moved to the open side. As a result, as shown in FIG. 8D, the panel 13 and the stacker 23 are arranged at the open position in FIG. 8 without colliding.

  When an open button operation signal is input, both the panel 13 and the stacker 23 are opened. When receiving print data, the stacker 23 is opened to receive the printed paper P. Further, when receiving label printing, a guide groove 24 (see FIGS. 3 and 6) for inserting a tray (not shown) on which a disk such as CDR or DVD is set is formed in the raised portion 23c of the stacker 23. If the stacker 23 protrudes, it is retracted into the main body 12. Further, the panel 13 is opened to a fully opened position (for example, about 90 degrees) (for example, a position indicated by a two-dot chain line opened in a horizontal state in FIG. 9A). By disposing the panel 13 in the fully open position, the panel 13 when inserting the tray does not get in the way, and the tray can be smoothly slid along the guide groove 24.

Next, the close control will be described with reference to FIG.
As shown in FIG. 9A, when the power is turned on, the panel 13 is disposed at the open position at a posture angle of about 45 degrees indicated by a solid line in FIG. Rotate. Therefore, the panel 13 may be disposed at a posture angle of about 10 degrees or a posture angle of about 90 degrees as indicated by a two-dot chain line in FIG. When the user performs a power-off operation in this state, the panel 13 indicated by a two-dot chain line positioned closer to the closing position than the open position indicated by the solid line in FIG. The opening operation is performed to the retracted position (that is, the open position) indicated by the solid line in FIG. At this time, the stacker 23 starts the closing operation almost simultaneously with the opening operation of the panel 13. On the other hand, when the panel 13 is located at the fully open position in FIG. 9A, the passage of the stacker 23 is secured, so that the rotation of the panel 13 to the retracted position (open position) indicated by the solid line in FIG. Not done.

  When the panel 13 is rotated to the retracted position, the stacker 23 during the closing operation reaches the open position shown in FIG. 9B, and the detection state of the second sensor 74 represents the closing state from the state indicating the opening of the stacker 23. When this is switched, the timer 114 starts counting the standby time WT using this as a trigger. Panel 13 waits for waiting time WT to elapse at the retracted position (open position). Then, when the standby time WT elapses, the stacker 23 reaches a predetermined position as indicated by an arrow in FIG. 9C, and the stacker 23 reaches the predetermined position, that is, the standby time WT has elapsed. Using the trigger, the closing operation of the panel 13 is started. The closing operation of the panel 13 is started when the stacker 23 reaches the predetermined position after the waiting time WT has elapsed after the stacker 23 has passed the open position in the closing direction. After moving to the close side, the panel 13 moves the interference region to the close side. As a result, as shown in FIGS. 9C and 9D, the panel 13 and the stacker 23 each move to the closed position without colliding (FIG. 9D). As described above, in the present embodiment, the timing for starting the movement of the panel 13 is set when the stacker 23 reaches a predetermined position, and the time when the stacker 23 reaches the predetermined position is acquired by counting the standby time WT.

  Further, when the stacker 23 starts the closing operation from a position closer to the closing position than the opening position (for example, FIG. 9C), the state indicating the opening of the second sensor 74 is changed to the state indicating the closing in the middle of the closing operation. The switch does not appear. In this example, when the position closer to the stacker 23 than the open position is set as the start position of the closing operation, the panel 13 and the stacker 23 do not interfere even if the panel 13 starts the closing operation immediately from the retracted position. It has become. Therefore, the panel 13 that has moved to the retracted position immediately starts a closing operation without waiting at the retracted position (open position).

  At the end of the print job, the stacker 23 is closed, but the panel 13 is moved to the original position before receiving the print job. Specifically, when a print job is received, the position (angle) of the panel 13 is stored in a predetermined storage area of the nonvolatile memory 103, and when the print job is completed, the panel is based on the original position data read from the nonvolatile memory 103. Control to return 13 to the original position is performed. When a label printing instruction is received, the current position (angle) of the panel 13 is stored in a predetermined storage area of the nonvolatile memory 103, and the panel 13 is retracted to the fully open position. Then, after label printing is performed on the disc on the tray inserted by the user, the user removes the tray from the guide groove 24 of the stacker 23. The removal of the tray is detected by a tray sensor 48 (see FIG. 7). When the removal of the tray is detected after the label printing is completed, the original position of the panel 13 at the time of receiving the label printing instruction is read from the nonvolatile memory 103, and the control to return the panel 13 to the original position (angle) read out is performed. .

Next, the operation of the printer 11 configured as described above will be described.
In the printer 11 of the present embodiment, the computer 85 accepts input of a power-on operation signal, input of an open button operation signal, reception of a print job, acceptance of a label print instruction, and the like as an open instruction. First, the computer 85 opens the panel 13 when a user inputs a power-on operation signal by operating the power switch 15a. In addition, when receiving a print job, the computer 85 opens the stacker 23. At the time of receiving the label printing of the disc, the panel 13 is opened to an angle that does not obstruct when the user inserts the tray along the guide groove 24 of the stacker 23, for example, a fully open position (90 degrees as an example). Upon receiving such an opening instruction, the computer 85 performs open control for opening at least one of the panel 13 and the stacker 23. In this open control, the control shown in FIGS. 8A to 8D is performed.

  In the printer 11 of this embodiment, the computer 85 accepts an input of a power-off operation signal, an input of a close button operation signal, the end of a print job, and the like as a close instruction (close instruction). When the power-off operation signal is input to the printer 11 and the close button operation signal is input, the computer 85 closes both the panel 13 and the stacker 23. When the print job is finished, the computer 85 closes the stacker 23 and controls the panel 13 to return to the original position when the print job is received. When the computer 85 accepts such a close instruction, the computer 85 performs close control for closing at least one of the panel 13 and the stacker 23. In this close control, the control shown in FIGS. 9A to 9D is performed. At the end of disc label printing, the computer 85 performs control to return the panel 13 opened to, for example, the fully opened position to the original position when receiving the label printing instruction.

  Hereinafter, the open control routine will be described first with reference to FIG. In the open control, when a power-on operation signal is input, an open button operation signal is input, a print job is received, and a label print instruction is received, the computer 85 that has received these as an open instruction executes the open control routine shown in FIG. Is done. FIG. 10 shows an example of open control executed by the computer 85 when the power is turned on. Hereinafter, the open control when a power-on operation is received will be described with reference to FIG. When the user operates the power switch 15a and receives a power-on operation signal, the computer 85 performs open control. This routine is executed by the CPU 100 in the computer 85 when the printer 11 is powered on.

  First, in step S11, only the panel is opened. By driving the first motor 50 in the forward direction, the panel 13 is opened from the closed position. At this time, the second motor 70 is not driven.

  In step S12, it is determined whether or not an overload is detected in the first motor. That is, it is determined whether or not an overload is detected during the opening operation of the panel 13. If no overload is detected in the first motor, the process proceeds to step S13, and if an overload is detected, the process proceeds to step S14.

  In step S13, it is determined whether or not a panel opening in which the panel reaches the open position and the detection state of the first sensor 63 switches from closed to open is detected. When the panel opening is detected, the process proceeds to step S14. When the panel opening is not detected, the process returns to step S12.

  In step S14, the panel is stopped. That is, the computer 85 stops the forward drive of the first motor 50. At this time, the panel 13 does not need to be stopped at the open position. For example, after the panel opening is detected by the first sensor 63, the first motor 50 is decelerated and stopped, and the panel 13 is opened from the open position. You may stop at the position.

  For example, if the stacker is in the projecting position as shown by the solid line in FIG. 8B when the stacker is in the proper position shown by the solid line in FIG. 8A, the panel 13 rotates from the closed position to the open position. As a result, it is unlikely that an overload will be detected during the opening operation unless the user holds it with his hand or places an obstacle. Thus, after the opening operation of the panel 13 is started, the opening operation is continued until the panel opening is detected. When the panel opening is detected, the opening operation of the panel 13 is stopped. On the other hand, as shown in FIG. 8C, when the raised portion 23 c of the stacker 23 is located on the path of the opening operation of the panel 13, the panel 13 is raised immediately after the panel 13 starts the opening operation. 23c. For this reason, when an overload is detected during the opening operation of the panel 13, the opening operation is interrupted at a position indicated by a two-dot chain line in FIG. 8C where the panel 13 collides with the raised portion 23c. In this case, the computer 85 causes the display unit 14 to display a message that prompts the user to manually open the panel.

  When the panel 13 is opened by the power-on operation in this way, the panel 13 is disposed at the open position indicated by the two-dot chain line in FIGS. 8A and 8B, or by the two-dot chain line in FIG. It arrange | positions in the position which collided with the protruding part 23c to show. In the printer 11 of the present embodiment, an opening operation for opening the stacker 23 by operating the operation switch 15b can be performed. And a user performs opening operation as needed.

  In step S16, it is determined whether or not an opening operation has been performed. That is, it is determined whether or not the user has attempted to open the stacker 23 by operating an operation switch or an icon button displayed on the display unit 14. If there is no opening operation, the process proceeds to step S16, and if there is an opening operation, the process proceeds to step S17.

  In step S16, it is determined whether print data has been received. It is determined whether print data (print job data) has been received. If print data is received, the process proceeds to step S17, and if print data is not received, the process returns to step S15.

  In step S17, it is determined whether or not the panel is in a closed state. If the first sensor 63 is off, the panel 13 is in a closed state, and if the first sensor 63 is on, the panel 13 is in an open state. If the panel 13 is not closed (that is, if it is open), the process proceeds to step S18, and if the panel 13 is closed, the process proceeds to step S19.

In step S18, only the stacker is opened.
In step S19, it is determined whether or not the stacker is in a closed state. If the stacker is not closed (that is, if it is open), the process proceeds to step S20, and if the stacker is closed, the process proceeds to step S21.

  In step S20, only the panel is opened. For example, as shown by a solid line in FIG. 8B, for example, when the user manually closes the panel 13 and the stacker 23 protrudes to the open position while the panel 13 is in the closed position, FIG. Only the panel 13 is opened as indicated by a two-dot chain line in FIG.

  In step S21, simultaneous open control is performed to open both the panel and the stacker. For example, as shown in FIG. 8 (c), when the panel 13 is opened, it collides with the stacker 23, and at the overload detection position due to the collision, the panel 13 moves to the raised portion 23c as shown by the two-dot chain line in the figure. When the computer 85 is stopped in the hit state, the computer 85 causes the first motor 50 and the second motor 70 to rotate forward at the same time. As a result, as indicated by an arrow in FIG. 8C, the panel 13 and the stacker 23 operate in the opening direction at the same time, so that they can be opened without colliding with each other, as shown in FIG. 8D. Thus, both the panel 13 and the stacker 23 operate to the open position.

  When the panel 13 collides with the stacker 23 and stops when the power is turned on, the operation may be shifted to the simultaneous open control to open the panel 13 to the open position. In this case, the first and second motors 50 and 70 are simultaneously driven in the normal direction to open the panel 13 and the stacker 23 together. When the panel 13 is opened to a position where it cannot collide with the stacker 23, the second motor 70 is driven in reverse to cause the stacker 23 to close. According to this configuration, even if only the panel 13 is opened, even if it collides with the stacker 23 located on the path, the panel 13 can be opened to the open position, and the stacker 23 returns to the closed position. Therefore, the stacker 23 does not get in the way. In addition, when the panel 13 collides with the stacker 23 and stops, it is good also as a structure which transfers to simultaneous open control and moves not only the panel 13 but the stacker 23 to an open position. In this case, the stacker 23 may be closed by control by driving the second motor 70 in the reverse direction from the open position, or may be closed manually by the user.

  Next, the close control routine will be described with reference to FIG. The close control routine is performed when the user turns off the power, when the close button is operated, when the print job ends, or when the stacker is pushed. That is, the CPU 100 of the computer 85, when the printer 11 is running (power is on), when a power-off operation signal is input from the power switch 15a, when a close button operation signal is input, when a print job is completed, or when a stacker pressing operation is detected. This close control routine is executed.

  First, in step S31, it is determined whether or not the stacker is in an open state. If the stacker 23 is in the open state, the process proceeds to step S32, and if the stacker 23 is not in the open state (that is, in the closed state), the process proceeds to step S38.

In step S32, the second motor is driven to close the stacker. That is, the CPU 100 rotates the second motor 70 in the reverse direction to close the stacker 23.
In step S33, it is determined whether or not the panel is in a closed state. If the panel is closed, the process proceeds to step S34, and if the panel is not closed (that is, if the panel is open), the process proceeds to step S35.

  In step S34, the first motor is driven to open the panel to the open position (retracted position). That is, the first motor 50 is driven to rotate forward to open the panel 13 until it reaches the open position (FIG. 5) where the first sensor 63 switches from the closed state to the open state.

  In step S35, it is determined whether or not the stacker is in a closed state. That is, it is determined whether the stacker 23 that has started the closing operation from the open state is detected by the second sensor 74 and switched from the open state to the closed state. If the stacker 23 is in the closed state, the process proceeds to step S36. If the stacker 23 remains in the open state, the process waits until the stacker 23 is in the closed state.

  In step S36, timing of the waiting time WT is started. That is, the CPU 100 starts measuring the standby time WT by the timer 114. For example, the standby time WT is set in the timer 114, and the countdown is performed until the value becomes 0 (zero).

  In step S37, it is determined whether standby time WT has elapsed. If the waiting time WT has not elapsed, the process waits until it elapses, and if the waiting time WT has elapsed, the process proceeds to step S41.

  Thus, when the stacker 23 is in the open state at the start of the closing control, the elapsed time from the time when the stacker 23 switches from open to closed is counted (for example, the timer 114 is counted down), and the panel 13 is changed from closed to open. Wait for the elapse of the waiting time WT at a predetermined position to be switched.

  In step S41, it is determined whether or not the print job has ended. That is, it is determined whether or not the current trigger for starting the close control is due to the end of the print job. If the print job is not completed, the process proceeds to step S42. If the print job is completed, the process proceeds to step S43. Here, as triggers for starting the closing control other than at the end of the print job, there are a user power-off operation, a close button operation, and a stacker push-in operation.

  In step S42, the first motor is driven to close the panel. That is, the CPU 100 drives the first motor 50 in the reverse direction to close the panel 13 from the open position (retracted position). If the panel 13 has not yet reached the open position when the standby time WT has elapsed, the closing operation of the panel 13 is started from the open position after reaching the open position.

  On the other hand, when the stacker 23 is in the closed state rather than the open position where the second sensor 74 switches from open to closed at the start of the close control (negative determination in S31), the following control is performed.

  In step S38, the second motor is driven to close the stacker. That is, the second motor 70 is driven in reverse to close the stacker 23. Since the stacker 23 starts the closing operation from the closed state, the switching position from the open state to the closed state does not pass. In the present embodiment, when the stacker 23 is in the closed state where the switching position from the open state to the closed state has already passed to the closed side, the standby time WT to wait for the panel 13 at the predetermined position (open position) is 0 ( Zero). For this reason, the timer 114 does not measure time.

  In step S39, it is determined whether or not the panel is in a closed state. If the panel is closed, the process proceeds to step S40, and if the panel is not closed (that is, if the panel is open), the process proceeds to step S41.

  In step S40, the first motor is driven to open the panel to the open position. That is, the first motor 50 is driven to rotate forward to open the panel 13 until it reaches the open position (FIG. 5) where the first sensor 63 switches from the closed state to the open state.

  In step S41, it is determined whether or not the print job has ended. That is, it is determined whether or not the current trigger for starting the close control is due to the end of the print job. If the print job is not completed, the process proceeds to step S42. If the print job is completed, the process proceeds to step S43. Here, as triggers for starting the closing control other than at the end of the print job, there are a user power-off operation, a close button operation, and a stacker push-in operation.

  In step S42, the first motor is driven to close the panel. That is, the first motor 50 is driven in reverse to close the panel 13 from the open position. Note that after the panel 13 reaches the open position, the closing operation is started from the open position. Thus, the panel 13 is closed to the fully closed position, but the panel 13 starts closing after waiting for the waiting time WT to elapse in the open position. In the middle of the closing operation, there is no collision with the stacker 23 that is also in the closing operation. On the other hand, when the print job is finished, the process of step S43 is performed.

  In step S43, the panel is moved to the position before the print job. That is, the CPU 100 reads the position of the panel 13 before the print job from a predetermined storage area of the nonvolatile memory 103, drives the first motor 50, and returns the panel 13 to that position. In this way, the panel 13 once retracted to a position that does not interfere with printing in order to execute the print job is automatically returned to the original position before the print job. For example, when the user manually adjusts the panel 13 to an easy-to-view angle, the panel 13 is automatically returned to the original position manually adjusted by the user.

  In step S <b> 44, the stacker close flag = 1 (closed) is written in the predetermined storage area of the nonvolatile memory 103. Thus, the fact that the stacker 23 is in the fully closed position is stored in the nonvolatile memory 103.

In step S45, the current position of the panel is stored. That is, the CPU 100 stores the current position of the panel 13 in a predetermined storage area of the nonvolatile memory 103.
According to the first embodiment described in detail above, the following effects can be obtained.

  (1) In the printer 11 in which the moving path for opening and closing the panel 13 and the moving path for moving the stacker 23 partially overlap, the computer 85 closes the stacker 23 when receiving a close instruction, and in the middle of the closing operation After the stacker 23 reaches the predetermined position, the closing operation of the panel 13 is started. Therefore, when the computer 85 closes the panel 13 and the stacker 23, the frequency of occurrence of collision between the two can be reduced.

  (2) When the computer 85 accepts the close instruction, if the panel 13 is positioned closer to the retracted position than avoiding interference with the stacker 23, the computer 85 temporarily opens the panel 13 to the retracted position and then closes the panel 13 from the retracted position. To start. For this reason, once the panel 13 opens to the retracted position, the passage of the stacker 23 can be secured. After the timing when the stacker 23 reaches a predetermined position and the two do not interfere with each other, the closing operation of the panel 13 from the retracted position is started. Therefore, the panel 13 and the stacker 23 can be closed while avoiding the collision between the two.

  (3) The position at which the first sensor 63 that detects the open position of the panel 13 changes from the state representing the close of the panel 13 to the state representing the open is defined as the retreat position. When opening the panel 13 from the closed position, the computer 85 opens the panel 13 to a position where the first sensor 63 changes from the closed state to the open state. Further, when both the panel 13 and the stacker 23 are closed, the panel 13 is retracted to a position where the first sensor 63 has changed from a state representing the closing of the panel 13 to a state representing the opening. Therefore, the control for opening the panel 13 and the control for closing the panel 13 can be performed using the common first sensor 63. For this reason, the number of parts can be reduced.

  (4) When the computer 85 starts the closing operation of the panel 13 after the stacker 23 reaches a predetermined position, in the interference region where the movement path of the panel 13 and the movement path of the stacker 23 partially overlap, After the stacker 23 first moves in the closing direction, the timing is adjusted so that the panel 13 moves in the closing direction. Therefore, the panel 13 and the stacker 23 can be closed together while avoiding a collision. For example, the panel 13 can be closed on the front surface of the main body 12 while the stacker 23 is housed in the main body 12. For example, if the timing of passing through the interference region between the panel 13 and the stacker 23 is reversed, the panel 13 that has been closed first on the housing side becomes an obstacle and the stacker 23 cannot be stored in the housing.

  (5) A second sensor 74 for detecting that the stacker 23 during the opening operation has reached the open position is provided. When opening the stacker 23, the computer 85 switches the second sensor 74 from the closed state to the open state to decelerate the second motor 70 and stop the stacker 23 in the open state. Further, when the panel 13 and the stacker 23 are closed, the second sensor 74 switches from the state representing the opening of the panel 13 to the state representing the closing, and then the panel 13 is closed after the waiting time WT has elapsed. To start. In the case of this example, since the friction clutch 79k exists in the power transmission mechanism 71 of the stacker 23, the absolute position of the stacker 23 cannot be managed, but the stacker 23 is opened while the stacker 23 is closed from the opened state by electric drive. The second sensor 74 is disposed at a position where the state to be displayed is switched to the state to be closed. Therefore, the 2nd sensor 74 used for control which opens stacker 23 can be used as a trigger which starts time-measurement of waiting time WT. For this reason, it can close, avoiding the collision with the panel 13 and the stacker 23. FIG. Therefore, the control for opening the stacker 23 and the control for closing the stacker 23 can be performed using the common second sensor 74. For this reason, the number of parts can be reduced.

  (6) When the computer 85 receives the closing instruction, if the stacker 23 is in a position closer to the predetermined position than the predetermined position, the computer 85 immediately starts the closing operation from the retracted position without waiting the panel 13 at the retracted position. Let Therefore, even when the second sensor 74 cannot detect the switching from the state representing the opening of the stacker 23 to the state representing the closing, the passage of the stacker 23 is secured by retreating the panel 13 to the retreat position, and the retreat position By starting the closing operation immediately without waiting in step 3, the delay of the start timing of the closing operation of the panel 13 can be reduced as much as possible.

  (7) When the computer 85 accepts the closing instruction, if the panel 13 is in an open position relative to the retracted position (open position), the computer 85 does not perform the closing operation to the retracted position (open position) and waits for When WT elapses, the closing operation is started. Therefore, it is possible to avoid a complicated closing operation in which the panel 13 starts the closing operation and temporarily stops (standby) at the halfway retracted position and then restarts the closing operation.

  (8) A stacker push-in assist control is adopted in which when the user pushes the stacker 23 lightly, the push-in operation is detected and the stacker 23 is automatically retracted to the fully closed position. Therefore, if the user pushes the stacker 23 lightly in order to manually close the stacker 23, the pushing operation is triggered and the stacker 23 is automatically closed, so that the user does not need to push the stacker to the fully closed position.

  (9) Since the operation that the user has pushed the stacker 23 is detected and triggered by this, the computer 85 drives the second motor 70 in the reverse direction to automatically close the stacker 23, so that the stacker 23 can be operated intuitively. .

(Second Embodiment)
In the present embodiment, the friction clutch in the power transmission mechanism 71 of the stacker 23 is eliminated, and the stacker 23 is directly connected to the second motor 70 via the power transmission mechanism 71. For this reason, the detection position of the second sensor 74 is used as a reference (origin), or the detection position when the stacker 23 detects an overload by hitting at least one of the end on the retracted position side and the end on the protruding position side. As a reference (origin), the current position in the movement range of the stacker 23 is managed as an absolute position.

  The first counter 115 is reset at the origin, counts the pulse edges of the detection pulse signal from the encoder 62, increments the count value when the first motor 50 rotates forward, and counts it when the first motor 50 rotates backward. Decrement the number. The second counter 116 is reset at the origin, counts the pulse edges of the detection pulse signal from the encoder 75, increments the count value when the second motor 70 is rotating forward, and when the second motor 70 rotates backward. The count value is decremented. In the present embodiment, the first counter 115 manages the position of the panel 13 as an absolute position, and the second counter 116 manages the position of the stacker 23 as an absolute position.

  In the first embodiment, when the panel 13 is located somewhere in the closed region, the panel 13 is once rotated to the open side until it is detected that the panel 13 is in the open position, and the stacker 23 is not in the open position. When the standby time WT has elapsed from the point in time, the panel 13 is caused to start a closing operation from the retracted position (open position). However, since the standby time WT is set based on the case where the panel 13 starts the closing operation from the open position, the panel 13 starts when the panel 13 starts the closing operation from a position between the open position and the fully open position. In some cases, the closing operation of the panel 13 is started after the start timing of the closing operation is delayed and the stacker 23 is completely closed.

  In contrast, in the second embodiment, the positions of the panel 13 and the stacker 23 are managed as absolute positions. Then, the computer 85 determines that the panel 13 has just moved from the absolute position of the panel 13 and the absolute position of the stacker 23 immediately after the raised portion 23c of the stacker 23 passes the overlapping path from the time when the stacker 23 starts to close. A waiting time WT1 at the current position of the panel 13 which is the timing of passing through the overlapping route is calculated. The stacker 23 measures the elapsed time from the time when the closing operation is started from the current position by the timer 114, and starts the closing operation of the panel 13 when the elapsed time reaches the standby time WT1.

Next, the closing control of this embodiment shown in FIG. 12 will be described.
When the computer 85 closes both the panel 13 and the stacker 23 such as when a power-off operation signal is input, the computer 85 controls the drive of the first motor 50 and the second motor 70 according to the close control routine shown in FIG.

In step S51, the panel position is acquired. That is, the CPU 100 acquires the absolute position of the panel 13 from the value of the first counter 115.
In step S52, the position of the stacker is acquired. That is, the CPU 100 acquires the absolute position of the stacker 23 from the value of the second counter 116.

  In step S53, the standby time WT1 is calculated using each position of the panel and the stacker. Even when both the panel 13 and the stacker 23 are started to close from the current position at that time, the standby time WT1 passes through the panel 13 immediately after the stacker 23 first passes through the overlapping portion of both paths. Calculated as a value that will be timing. For example, the required time T1 from the current position (absolute position) of the stacker 23 to the position in the overlapping region of the route is calculated using a known speed profile when the stacker 23 is closed. Further, the required time T2 from the current position (absolute position) of the panel 13 to the position in the overlapping region of the route is calculated using a known speed profile when the panel 13 is closed. Then, a standby time WT1 that satisfies T1 <T2 + WT1 is calculated. In this example, a margin time ΔT for avoiding the collision between the panel 13 and the stacker 23 is set, and as an example, the standby time WT is calculated by the equation WT1 = T1−T2 + ΔT.

In step S54, the second motor is driven to close the stacker. That is, the CPU 100 rotates the second motor 70 in the reverse direction to close the stacker 23.
In step S55, timing of standby time WT1 is started. That is, the CPU 100 starts measuring the standby time WT1 by the timer 114 at the timing when the closing operation of the stacker 23 is started.

  In step S56, it is determined whether standby time WT1 has elapsed. If the standby time WT has not elapsed, the process waits until it elapses, and if the standby time WT has elapsed, the process proceeds to step S57. Thus, the panel 13 stands by at the current position from the start of the closing operation of the stacker 23 that started the closing operation from the current position at the start of the closing control until the waiting time WT1 has elapsed. And when standby | waiting time WT1 passes, it will progress to step S57.

  The subsequent steps S57 to S61 are the same as the steps S41 to S45 in the first embodiment. That is, in step S57, it is determined whether or not the print job is finished. That is, it is determined whether or not the current trigger for starting the close control is due to the end of the print job. If the print job is not completed, the process proceeds to step S58. If the print job is completed, the process proceeds to step S59. Here, as triggers for starting the closing control other than at the end of the print job, there are a user power-off operation, a close button operation, and a stacker push-in operation.

  In step S58, the first motor is driven to close the panel. That is, the CPU 100 drives the first motor 50 in the reverse direction to close the panel 13 from the current position. In this way, from the start of the closing operation of the stacker 23, the panel 13 starts the closing operation from the current position after waiting for the waiting time WT1 to elapse at the current position, so immediately after the stacker 23 has passed in the portion where the path overlaps with the stacker 23. In the middle of the closing operation, there is no collision with the stacker 23 that is also in the closing operation. On the other hand, when the print job is finished, the process of step S59 is performed.

  In step S59, the panel is moved to the position before the print job. That is, the CPU 100 reads the position of the panel 13 before the print job from the predetermined storage area of the nonvolatile memory 103, drives the first motor 50, and returns the panel 13 to the original position. In this way, the panel 13 once retracted to a position that does not interfere with printing in order to execute the print job is automatically returned to the original position before the print job. For example, when the user manually adjusts the panel 13 to an easy-to-view angle, the panel 13 is automatically returned to the original position manually adjusted by the user.

  In step S <b> 60, the stacker close flag = 1 (closed) is written in the predetermined storage area of the nonvolatile memory 103. Thus, the fact that the stacker 23 is in the fully closed position is stored in the nonvolatile memory 103.

In step S61, the current position of the panel is stored. That is, the CPU 100 stores the current position (absolute position) of the panel 13 in a predetermined storage area of the nonvolatile memory 103.
According to the second embodiment described in detail above, the following effects can be obtained.

  (10) The first counter 115 and the first sensor 63 that constitute the first position management unit that manages the position of the panel 13 in the movable range, and the second position management unit that manages the position of the stacker 23 in the movable range are configured. A second counter 116 and a second sensor 74 are provided. The absolute position of the panel 13 and the absolute position of the stacker 23 are managed, and the waiting time WT1 for which the panel 13 should wait is calculated from the respective current positions of the panel 13 and the stacker 23 when the closing instruction is received. Then, when the standby time WT1 has elapsed after the stacker 23 starts the closing operation, the panel 13 is caused to start the closing operation from the current position. For this reason, an appropriate waiting time WT1 corresponding to the current position is calculated regardless of the position at which the panel 13 and the stacker 23 start the closing operation, so that the collision between the panel 13 and the stacker 23 is avoided. A large shift in the timing of closing between the two can be suppressed. In the first embodiment, since the waiting time WT is constant, the panel 13 and the stacker 23 may close cleanly almost simultaneously, or there may be an excessive shift in the time that the panel 13 closes after the stacker 23 closes first. Sometimes it becomes. On the other hand, in the second embodiment, since the variable waiting time WT1 corresponding to each position of the panel 13 and the stacker 23 is calculated, the panel 13 and the stacker 23 do not collide and close at an exquisite timing. be able to.

  (11) After the closing operation of the stacker 23 is started, the closing operation of the panel 13 is started after waiting for the standby time WT1. For this reason, the closing operation of both can be started from the position of the panel 13 and the position of the stacker 23 when the closing instruction is received. In the first embodiment, when the stacker 23 reaches a predetermined position before the panel 13 is completely opened to the retracted position (open position), the remaining angle from the time point until the panel 13 reaches the retracted position (open position). The operation until it is further opened is a waste of time. On the other hand, according to this configuration, the panel 13 is opened to secure the passage of the stacker 23 until the retracted position (for example, a value within a range of 30 to 40 degrees) where the two do not interfere with each other. The closing operation can be started from the position when the is received. For this reason, the useless operation | movement which opens the panel 13 once can be decreased, and the smart closing operation as much as possible is realizable.

In addition, the said embodiment can also be changed into the following forms.
In the process of opening the panel, the position (angle θ1) at which the first sensor 63 switches from the state indicating the closing of the panel 13 to the state indicating the opening, that is, the opening position and the retracting position of the panel 13 is, for example, about 30 degrees. , About 45 degrees, about 60 degrees, etc., and not limited to positions within the intermediate angle region between fully closed and fully open. The position at which the first sensor 63 switches from the closed state to the open state (angle θ1) may be a fully open angle (90 degrees as an example). In addition, fully open refers to the angular position opened to the maximum within the movable range of the panel. Further, if the predetermined position is the fully opened position, the fully opened position can be detected by detecting an overload when the panel 13 hits the fully opened end without using the first sensor 63. It can also be configured to detect that the position has been reached. In this case, the number of component parts can be reduced by eliminating the first sensor 63. When the open position and the retracted position are the same, the panel 13 is retracted to the fully open position, so that the passage of the stacker 23 can be reliably ensured.

  When the computer 85 receives the close instruction, if the stacker 23 is in a position closer to the closed position than the predetermined position, the panel 13 is not in the interference region even if it is closer to the closed position than the retracted position. May be closed without being moved to the retracted position. According to this configuration, the passage of the stacker 23 can be secured and the delay of the start timing of the closing operation of the panel 13 can be further reduced.

  -In the said 2nd Embodiment, although the absolute position was managed by both the panel 13 and the stacker 23, you may manage only at least one by an absolute position. For example, only the panel may be managed at an absolute position. In this case, the standby time WT2 of the panel 13 after reaching the position where the stacker 23 switches from open to closed is calculated and acquired according to the current position (absolute position) of the panel, and the stacker 23 is changed from open to closed. When the standby time WT2 elapses from the time of switching, the closing operation from the current position of the panel 13 is started. In this case, the panel 13 may be closed from the current position when the close instruction is received without returning to the retracted position (open position) where the panel 13 is switched from closed to open. For example, only the stacker may be managed at the absolute position. In this case, the standby time WT3 at the predetermined position of the panel 13 when the stacker 23 starts the closing operation from the current position is calculated and acquired according to the current position (absolute position) of the panel 13, and the stacker 23 When the standby time WT3 has elapsed from the time when the closing operation is started from the current position when the closing instruction is received, the closing operation from the current position of the panel 13 returned to the predetermined position is started. According to this configuration, the panel 13 is returned to the retracted position where the panel 13 is switched from closed to open, but the time required to return to the retracted position is equal to the waiting time WT3 without waiting for a predetermined time after returning to the retracted position. Since it is included in a part, it can be avoided that the panel 13 waits too much at the retracted position. For this reason, the timing of the closing operation of the panel 13 and the stacker 23 is optimized, and the closing control can be finished early.

  In the second embodiment, the standby time WT1 is calculated. However, even if the closing operation of the panel 13 is started from the current position, it does not collide with the stacker 23 and can be closed without much time (panel). When the stacker 23 reaches the panel closing operation start position, the closing operation of the panel 13 is started. In this case, when the current position of the stacker 23 (position before starting the closing operation) is already the same as or close to the panel closing operation start position, the closing operation of the panel 13 and the stacker 23 is started simultaneously. Let According to this configuration, just by managing the position of the stacker 23 without measuring the time with the timer 114, as in the second embodiment, while eliminating the useless operation of returning the panel 13 to the open position, The panel 13 and the stacker 23 can be closed together more smoothly while avoiding a collision. For example, even if the panel 13 is once moved to the open position, a shift in the closing operation timing at which the closing operation of the panel 13 is started after the stacker 23 is completely closed can be suppressed.

In the second embodiment, the second sensor on the stacker side may be eliminated. The position may be managed based on the end by detecting that the stacker 23 hits one end.
The friction clutch included in the power transmission mechanism on the stacker 23 side may be abolished, and the absolute position may be managed by counting the detection pulses of the encoder 75 on the stacker side.

The trigger for starting the close control may be one of a user power-off operation, a close button operation, a print job end, and a stacker push-in operation.
・ The panel open position and retracted position are the same position, and the open position and retracted position are detected using the common first sensor, but the panel open position and retracted position are set to different positions. However, each may be detected by a different sensor. According to this configuration, since the retracted position can be set to an appropriate position different from the open position, the closing operation start timing from the standby position is delayed due to the standby time passing before the panel is moved to the open position. The frequency can be reduced.

  The amount of protrusion (projection amount) of the stacker 23 from the main body 12 that determines the receiving position of the stacker 23 is not constant, and may be changed according to the length of the paper P to be discharged. Also in this case, the collision between the panel 13 and the stacker 23 can be avoided by performing the collision avoidance control.

  The power source of the stacker and the power source of the panel may be changed to dedicated ones, and one of the power source of the stacker and the power source of the panel may serve as a motor provided for other purposes. For example, the transport motor 33 may serve as one of the power source of the panel 13 and the power source of the stacker 23. In this case, a clutch capable of switching the power transmission destination of the transport motor 33 to a stacker or a panel may be provided. As the clutch, an electric clutch may be used, and a mechanical clutch that switches the clutch by operating the switching lever by driving the carriage motor and moving the carriage to a predetermined position can be exemplified.

  -The stacker may be a rotary type. For example, the stacker rotates on the front surface of the main body around the lower end, and moves between a closed position that closes along the front surface of the main body 12 and an open position that protrudes in a direction substantially orthogonal to the front surface of the main body. The configuration. In this case, the panel is, for example, a rotary type as in the above embodiment. In this configuration, both the panel and the stacker are pivotable, so if the closing operation is started at the same time, they will collide in the interference area, but the panel is temporarily opened to the retracted position, and a path for the stacker to move in the closing direction is secured. In addition, after the stacker is closed to a predetermined position (predetermined attitude angle), the closing operation from the retracted position of the panel may be started.

  -The panel may be movable, combining slide and rotation. For example, the panel slides from the inside of the main body and protrudes outward, and after the protrusion, the panel is rotated and arranged at a predetermined rotation angle.

The stacker is composed of a single plate-shaped tray, but it may be configured to move out and retract by expanding and contracting a multistage tray.
The panel may be provided with only a touch panel type display unit that does not include an operation unit such as an operation switch but allows an input operation by touching the screen with a hand. Moreover, the structure provided only with the operation part without providing a display part may be sufficient.

-The power source is not limited to a rotary motor, and may be a linear motor.
The medium is not limited to paper, and may be a resin film, a metal foil, a metal film, a resin-metal composite film (laminate film), a woven fabric, a nonwoven fabric, a ceramic sheet, or the like.

  The recording apparatus is not limited to the ink jet type, and may be a dot impact type or a laser type. Furthermore, the recording apparatus is not limited to a serial printer, and may be a line printer or a page printer. For example, in the line printer, since the conveyance of the medium and the recording on the medium are performed at the same time, the timing for starting the movement of the stacker to the position corresponding to the medium length in the panel and stacker operation in the first embodiment is as follows. The timing is during conveyance and recording.
