Description

  The present invention includes a recording unit that performs recording on a recording medium, and a first position and a second position that are rotated about a rotation axis, and from the recording unit at the second position. The present invention relates to a recording apparatus including a stack unit on which a discharged recording medium is placed.

  In the present application, the recording apparatus includes types such as an ink jet printer, a wire dot printer, a laser printer, a line printer, a copying machine, and a facsimile.

  Conventionally, as shown in Patent Document 1, there has been a recording apparatus capable of recording large-sized roll paper. The recording apparatus is provided so that the roll paper is fed to the recording unit downstream in the feeding direction by the feeding unit. The paper was recorded by the recording unit and discharged by the paper discharge unit. The discharged paper is usually placed on a stacker provided on the legs.

However, it is necessary to enlarge the stacker as the corresponding paper size increases. Specifically, it is necessary to extend the stacker in the length direction of the paper.
Japanese Patent Laid-Open No. 2007-261086

  However, when the stacker is extended in the length direction of the paper, the stacker protrudes in the width direction or depth direction with respect to the recording apparatus main body. In such a case, the user must rotate the leg ring to use the recording apparatus away from the indoor wall. For example, when the stacker protrudes rearward behind the recording apparatus, the user needs to move the recording apparatus forward and use the recording apparatus main body away from the wall. Such usage is not common. Further, it may be difficult to visually recognize the state of the stacker from the position of the user. Therefore, the user may unintentionally push and move the recording apparatus main body to the wall side. In such a case, an excessive force may act on the stacker and the stacker may be damaged.

  The present invention has been made in view of such a situation, and the problem is that, when the recording apparatus main body moves for some reason, there is a possibility that the stack portion on which the discharged recording medium is placed is damaged. Is to provide no recording device.

  In order to achieve the above object, a recording apparatus according to a first aspect of the present invention includes a recording unit that performs recording on a recording medium, and a first position and a second position by rotation about a rotation shaft. A stack portion on which the recording medium ejected from the recording portion at the second position is placed, and the free end side of the stack portion at the second position is the recording device When pressed against the opposing surface, a force for rotating the stack portion toward the first position is generated.

  According to the first aspect of the present invention, the recording apparatus may be configured such that when the free end side of the stack portion at the second position is pressed against a surface facing the recording apparatus, the first stack portion has the first portion. A force to rotate the position side is generated. Therefore, when the stack part is pressed against the opposing surface, the stack part can be rotated to the first position side and retracted. That is, the stack portion can be automatically stored when pressed against the opposing surface.

For example, when the recording apparatus is pushed and moved to the wall side which is an example of the facing surface, the stack portion in the second position state can be retracted to the first position side. As a result, there is no possibility that the stack portion is damaged. This is particularly effective when the stack portion at the second position is configured to protrude in one direction in the front-rear and left-right directions in the recording apparatus.
Further, when the recording apparatus can record on a recording medium of B0 size or larger, the stack portion needs to be provided large so that a recording medium of B0 size or larger can be placed. In this case, the stack portion at the second position protrudes in one direction, front, back, left, and right in the recording apparatus. This is especially effective in such cases.

  A recording apparatus according to a second aspect of the present invention includes a recording unit that performs recording on a recording medium, and a first position and a second position that are rotated about a rotation axis. A stack portion on which the recording medium ejected from the recording portion at the second position is placed, and a surface facing the recording device which is a free end side of the stack portion at the second position The contact point is on the first position side in the rotation direction of the stack portion with respect to a vertical line passing through the rotation axis on the facing surface.

  According to the second aspect of the present invention, the contact point with the surface facing the recording apparatus which is the free end side of the stack portion at the second position is the rotation axis on the facing surface. It is the 1st position side in the rotation direction of the stack part from the perpendicular line which passes. Therefore, when the stack part is pressed against the opposing surface, the stack part can be rotated to the first position side and retracted. As a result, the same effect as the first aspect can be obtained.

According to a third aspect of the present invention, in the first or second aspect, the stack unit has a leg ring that can freely change the direction, and the stack unit has the operation unit when the operation unit of the recording device is in the front. It is provided at the rear of the recording apparatus, and is rotated backward from the first position to the second position.
According to the third aspect of the present invention, in addition to the same function and effect as the first or second aspect, the leg portion can be freely changed in direction, and the stack portion operates the recording apparatus. This is provided at the rear of the recording apparatus when the part is the front, and is rotated backward from the first position to the second position. In other words, the stack portion at the second position protrudes rearward behind the recording apparatus.

Here, there is a possibility that the user cannot visually recognize that the stack portion is in the second position state. Furthermore, the recording apparatus provided with the leg ring is easy to move.
Therefore, there is a possibility that the user rotates the leg ring to move the recording apparatus backward, and erroneously presses the recording apparatus against the rear wall or the like. In such a case, the stack portion can be retreated, which is particularly effective.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the contact portion that contacts the opposing surface on the free end side of the stack portion has a rotatable roller. It is characterized by.
According to the fourth aspect of the present invention, in addition to the same function and effect as in any one of the first to third aspects, the abutting portion that abuts against the facing surface on the free end side of the stack portion, It has a rotatable roller. Therefore, it is possible to reduce the frictional resistance generated between the corresponding contact portion and the facing surface. As a result, the stack portion at the second position can be easily retreated to the first position side.
In addition, it is possible to reduce the possibility of scarring on the facing surfaces.

According to a fifth aspect of the present invention, in any one of the first to fourth aspects, when the stack portion rotates from the second position to the first position side, the free end side of the stack portion is arranged. The contact portion that contacts the facing surface is formed in an arc shape so that a contact point with the facing surface in the radial direction of the stack portion gradually moves toward the rotating shaft. To do.
According to the fifth aspect of the present invention, in addition to the same effect as any one of the first to fourth aspects, when the stack portion rotates from the second position to the first position side, The contact portion that contacts the opposing surface on the free end side of the stack portion has an arc shape so that the contact point with the opposing surface in the radial direction of the stack portion gradually moves toward the rotating shaft. Is formed. Therefore, when the contact portion slides on the opposing surface, it can be smoothly slid. As a result, the stack portion at the second position can be easily retreated to the first position side.

In addition, since the contact point gradually moves toward the rotating shaft, the force relating to the free end of the stack portion can be gradually reduced. As a result, the possibility that the free end side of the stack portion is deformed can be reduced. This is particularly effective when the stack portion is relatively large.
Furthermore, by making the arc shape, the moving distance of the contact point on the facing surface can be shortened as compared with the case where the arc shape is not provided. As a result, the length of scars that may occur on the opposing surfaces can be shortened.

A sixth aspect of the present invention is characterized in that, in any one of the first to fifth aspects, recording can be performed on a recording medium having a length in the feed direction of B0 size or more.
According to the sixth aspect of the present invention, in addition to the same effects as in any one of the first to fifth aspects, recording is performed on a recording medium whose length in the feed direction is B0 size or more. be able to.
Here, if the recording is performed on a recording medium having a length in the discharge direction of B0 size or more, the stack portion needs to be provided correspondingly. Accordingly, the stack portion at the second position protrudes in one direction, front, back, left, and right in the recording apparatus. This is especially effective in such cases.

According to a seventh aspect of the present invention, in any one of the first to sixth aspects, the film-like low friction extending in the discharge direction on the surface side of the stack portion on which the recording medium is placed. A member is provided.
According to the seventh aspect of the present invention, in addition to the same function and effect as in any one of the first to sixth aspects, the stack portion extends in the discharge direction on the surface side on which the recording medium is placed. A provided film-like low friction member is provided. Accordingly, it is possible to reduce the frictional resistance generated between the discharged recording medium and the stack portion.
Here, especially when the size of the recording medium is B0 size or more, the frictional resistance tends to increase due to its own weight. Then, there is a possibility that the recording medium stops in the middle of discharge and a so-called discharge jam occurs due to defective discharge.
In such a case, defective discharge can be prevented and effective.

Furthermore, a rear stack 20 is provided behind the printer 1. The rear stack 20 is configured to be used when recording a sheet P having a length of B0 or more. The rear stack 20 is provided so as to protrude rearward from the printer main body 2 in order to ensure a length for placing the rear stack 20.
Further, below the base 9, four leg rings 52, 52,... Which can be freely changed in direction are provided.
Hereinafter, the rear stack 20 will be described.

FIG. 2 is a side view of the printer in the rear stack storage state according to the present invention. FIG. 3 is a side view of the printer in the use state of the rear stack according to the present invention.
FIG. 4 is an enlarged rear perspective view showing the rear stack in the use state. FIG. 5 is a side view of FIG.
FIG. 6 is an enlarged perspective view of the main part showing the position of the rotation axis of the rear stack in the stored state. FIG. 7 is an enlarged perspective view of a main part showing the position of the rotation axis of the rear stack in the use state.

As shown in FIGS. 2 and 3, the stacker 10 below the printer 1 includes a front stack 11 and a rear stack 20 when the operation unit 60 is the front.
Among these, the front stack 11 includes front pipes 12 and 12, a first cloth sheet 30, and arm portions 14 and 14. A pair of front pipes 12 and 12 and arm portions 14 and 14 are provided in the width direction X of the paper P, respectively. The pair of front pipes 12 and 12 are provided so as to be swingable about a first rotation shaft 13 provided on the base 9. Similarly, the pair of arm portions 14 and 14 are provided so as to be swingable about an arm rotation shaft 15 provided on the base 9 as a fulcrum.

Therefore, the first cloth sheet 30 can be tightly tensioned by swinging the pair of front pipes 12 and 12 backward and swinging the pair of arm portions 14 and 14 forward. In this state, the paper P discharged from the opening 7 can be guided forward and discharged.
On the other hand, when the pair of front pipes 12 and 12 are swung forward, the first cloth sheet 30 can be loosened. And it can comprise so that the 2nd cloth sheet 31 may be located just under the opening part 7. FIG. Therefore, in this state, the paper P discharged from the opening 7 can be guided backward, that is, to the rear stack 20.

  As shown in FIGS. 2 to 5, the rear stack 20 includes stack frame portions 21, 21, a joint portion 23, a second cloth sheet 31, film materials 40, 40..., A first cloth fixing shaft 50, And a second cloth fixing shaft 51. A pair of stack frame portions 21, 21 are provided in the width direction X of the paper P. The second pivot shaft 22 provided on the base 9 is swingable about a fulcrum. The joint portion 23 is provided to connect the pair of stack frame portions 21 and 21 to the free end side of the stack frame portions 21 and 21.

  The second cloth sheet 31 is fixed by a first cloth fixing shaft 50 and a second cloth fixing shaft 51 provided on the base 9. Further, the upstream end in the discharge direction, which is the front side of the second cloth sheet 31, is attached to the front ends of the front pipes 12, 12, similarly to the first cloth sheet 30. On the other hand, the downstream end of the second cloth sheet 31 in the discharge direction is attached to the joint portion 23.

Here, the positional relationship between the first cloth fixing shaft 50 and the second cloth fixing shaft 51 is configured such that the second cloth fixing shaft 51 is positioned lower than the first cloth fixing shaft 50. Accordingly, the discharged paper P can easily travel downstream in the discharging direction due to its own weight.
The first cloth fixing shaft 50 and the second cloth fixing shaft 51 are configured to fix the second cloth sheet 31 by being inserted into a hole formed by being wound around the second cloth sheet 31 about once. (See FIGS. 6 and 7).

Further, a plurality of film materials 40, 40, which are low friction members such as plastic, are extended in the discharge direction Y on the upper surface side of the second cloth sheet 31. Specifically, the film materials 40, 40... Are second in three places, ie, first locking portions 41, 41..., Second locking portions 42, 42... And third locking portions 43, 43. The cloth sheet 31 is locked.
Therefore, when bending members having different bending conditions, different diameters (R) can be drawn, and there is no possibility that the bending will be hindered.

  As a result, as shown in FIG. 2, the rear stack 20 can be stored without difficulty. At this time, the second cloth sheet 31 is tightly stretched between the second cloth fixing shaft 51 and the joint portion 23. Therefore, it looks good. Further, there is no possibility that the second sheet contacts the floor U when the printer 1 is moved in the stored state. Therefore, when the printer 1 is moved, there is no possibility that the second cloth sheet 31 becomes dirty.

  As shown in FIGS. 6 and 7, the second rotation shaft 22 is provided above the position of the second cloth fixing shaft 51. Therefore, the difference between the distance from the portion where the second cloth sheet 31 is attached in the joint portion 23 to the second rotating shaft 22 and the distance from the portion to the second cloth fixing shaft 51 is the difference of the rear stack 20. Changes with rotation. Specifically, the rear stack 20 is rotated from the housed state to the used state, and the difference is reduced. Furthermore, in other words, the distance from the said location to the 2nd cloth fixed axis | shaft 51 becomes short gradually. As a result, in the use state, the second cloth sheet 31 is loosened and separated from the film materials 40, 40... Between the second cloth fixing shaft 51 and the third locking portions 43, 43.

  At this time, the film materials 40, 40... Are tightly stretched from the second locking portions 42, 42... To the third locking portions 43, 43. Accordingly, the discharged paper P can be smoothly guided downstream in the discharge direction. At this time, since the paper P is gradually discharged, its own weight acting on the paper P gradually increases. Accordingly, the frictional resistance generated between the paper P and the rear stack 20 is gradually increased. Although it depends on the thickness of the paper P, it is easily affected by frictional resistance, particularly in the case of the B0 size or larger.

Therefore, as described above, the second cloth sheet 31 is loosened between the second cloth fixing shaft 51 and the third locking portions 43, 43... And separated from the film materials 40, 40. Has been. Accordingly, only the film materials 40, 40,... Having low frictional resistance can be brought into contact with the paper P between the second cloth fixing shaft 51 and the third locking portions 43, 43,.
As a result, the increase in frictional resistance that increases with the discharge of the paper P can be minimized. In addition, since the frictional resistance is large, it is possible to reduce the possibility that the paper P is jammed on the upstream side in the discharge direction in the rear stack 20. That is, it is possible to prevent a so-called discharge jam that is a discharge failure.

  Further, the second cloth sheet 31 is slackened between the second cloth fixing shaft 51 and the third locking portions 43, 43..., But the second cloth sheet 31 includes the film material 40, 40. Is located between. Therefore, even when the paper P hangs between the film materials 40, 40... Or from the outside, there is no possibility that the paper P directly touches the floor U. As a result, there is no possibility that the paper P contacts the floor U and gets dirty.

FIGS. 8A to 8C are plan views showing the locking portions of the film material. Among these, FIG. 8 (A) is a 1st latching | locking part. FIG. 8B shows the second locking portion. Further, FIG. 8C shows a third locking portion.

Here, the first pieces 41a, 41a, ... are inserted from the upstream side toward the downstream side in the discharge direction.

Therefore, it is possible to counter the force that pulls the film materials 40, 40... From the first locking portions 41, 41. As a result, the first pieces 41a, 41a,... Are not easily removed, and there is no possibility that the first locking portions 41, 41,.
The shape of the first pieces 41a, 41a,... Has an effect of making it difficult to remove by increasing the tip side in the direction in which the first slit hole 32 is provided.
Moreover, 1st latching | locking part 41,41 ...-3rd latching | locking part 43,43 ... is provided in the same position in the discharge direction Y in each film material 40,40 ....

  As shown in FIG. 8B, the second locking portion 42 includes two second pieces 42a and 42b provided on the film material side and two second slit holes 33 provided on the second cloth sheet side. , 33. And the 2nd piece 42a, 42b is penetrated by each 2nd slit hole 33, 33, and the film material 40, 40 ... can be latched to the 2nd cloth sheet 31. FIG.

Here, one of the second pieces 42a, 42a... Is inserted from the upstream side in the discharge direction toward the downstream side. The other second pieces 42b, 42b... Are inserted from the downstream side in the discharge direction toward the upstream side.
Therefore, it is possible to counter the force pulling the film members 40, 40... From the second locking portions 42, 42. As a result, the second pieces 42a, 42a,..., 42b, 42b... Are not easily pulled out, and there is no possibility that the second locking portions 42, 42.

As shown in FIG. 8C, the third locking portion 43 has a third piece 43a provided on the film material side and a third slit hole 34 provided on the second cloth sheet side. And the film material 40, 40 ... can be latched to the 2nd cloth sheet 31 by the 3rd piece 43a being penetrated by the 3rd slit hole 34. As shown in FIG.
Here, the third pieces 43a, 43a... Are inserted from the downstream side in the discharge direction toward the upstream side.

Therefore, it is possible to counter the force of pulling the film materials 40, 40... From the third locking portions 43, 43. As a result, the third pieces 43a, 43a,... Are not easily pulled out, and there is no possibility that the locking of the third locking portions 43, 43,. This is particularly effective when the second fabric sheet 31 is loosened when the rear stack 20 is rotated from the stored state to the used state.
Further, since the film materials 40, 40... Can be locked to the second cloth sheet 31 without using a tool, it is easy to use when the user assembles and replaces parts.

9A and 9B are side views showing the operation of the rear stack. Among these, FIG. 9 (A) shows the time when the joint portion abuts against the wall. On the other hand, FIG. 9B shows a state where the printer is pushed to the wall side from the state of FIG.
As shown in FIG. 9A, when the joint portion 23 comes into contact with the wall T for some reason, the contact point H between the joint portion 23 and the wall T is a vertical line on the wall T passing through the second rotation shaft 22. From S, it is comprised so that it may be the position side of the accommodation state. Therefore, when the printer 1 is pushed toward the wall T when the rear stack 20 is in use, a force F that rotates the rear stack 20 in the retracted state, that is, a vector component can be generated.

  Here, by providing the rollers 24, 24, 24... In the joint portion 23, it is possible to reduce the frictional resistance generated between the joint portion 23 and the wall T. Specifically, the frictional resistance can be reduced by arranging the rollers 24, 24, 24... Slightly protruding from the surface of the joint portion 23. Therefore, the vector component F can be applied to the rear stack 20 more efficiently.

  As shown in FIG. 9B, when the printer 1 is further pushed to the wall side and moved from the state of FIG. 9A, the vector component F acts, so that the rear stack 20 rotates to the position side in the retracted state.

That is, the rear stack 20 can be retreated to the position side in the stored state. As a result, there is no possibility that the rear stack 20 is damaged.

Here, the joint portion 23 is formed in an arc shape so that the contact point H gradually approaches the second rotation shaft 22 as the storage portion is turned to the position side. Therefore, the range of the sliding portion, which is the movement range of the contact point H on the wall T, can be reduced as compared with the case where the arc is not formed. As a result, the length of scars that may occur on the wall T can be shortened.
Further, by providing the joints 23 with the rollers 24, 24, 24..., It is possible to reduce the possibility of scratches themselves.
