Description

  The present invention relates to a continuous paper processing apparatus and a continuous paper processing method for performing processing such as printing or thermal activation on continuous paper.

  2. Description of the Related Art Conventionally, there is known a continuous paper processing apparatus that sequentially feeds continuous paper from a roll body, performs processing such as printing or thermal activation on the fed continuous paper, and cuts the processed portion to obtain cut paper. It is.

As a method of holding the roll body in such a continuous paper processing apparatus, as disclosed in Patent Document 1, a central axis (roll axis) is inserted into the central hole of the roll body, and the roll of the central axis There is a method of supporting an end portion protruding laterally from the body with a frame (first conventional example). Further, as disclosed in Patent Document 2, there is a method in which a fitting portion of a bobbin (holder) provided in a frame is inserted and supported from the side into a center hole of a roll body (second conventional technique). Example).

  In the first conventional example described above, the operation of inserting the central axis into the central hole of the roll body and the operation of mounting the central axis in a state of holding the roll body on the frame are necessary and cumbersome. In addition, the user must be careful not to accidentally lose the center axis that can be attached to and detached from the frame and to prevent the subsequent roll body from being supported. In particular, when the user misunderstands that the central axis is an accessory of the roll body, after the processing of all the continuous paper fed out from the roll body is completed, the central axis is changed as the roll body is consumed. When the new roll body is discarded after that, there is a possibility that the roll body cannot be held because there is no central axis.

  In the second conventional example, since the bobbin is provided in the frame so as not to be detached, it is not mistakenly lost as in the first conventional example. Further, since the holding of the roll body is completed by only one operation for inserting the bobbin into the center hole of the roll body, the number of work steps is reduced as compared with the first conventional example that requires two operations. However, the operation of inserting the bobbin into the center hole of the roll body in the narrow space of the roll body housing portion is very complicated. Specifically, the user can position the bobbin fitting portion and the center hole of the roll body by groping and move the bobbin fitting portion with respect to the frame in order to insert the bobbin fitting portion into the center hole. It is very cumbersome. In particular, when the clearance between the fitting portion of the bobbin and the center hole of the roll body is small, the alignment and insertion work becomes more complicated. Further, at the time of alignment or mounting, the side of the roll body may be damaged by the tip of the fitting portion of the bobbin, and there is a possibility that scratches or deformations may remain on the edge of the continuous paper.

  In these first and second conventional examples, unless the roll body is set at an accurate position by the central axis and the bobbin, it is impossible to feed the continuous paper from the roll body and supply it to the processing unit.

  On the other hand, in the third and fourth conventional examples, the roll body is simply thrown into the roll body accommodating portion without requiring an attaching operation such as inserting a center shaft or a bobbin fitting portion into the center hole of the roll body. Therefore, workability is very good.

  An example of such a configuration is shown in FIG. In this configuration, the processing unit 3 is provided above and to the side of the roll body accommodating portion 2 (a position shifted in the horizontal direction from a position directly above the central axis of the roll body 1a accommodated in the roll body accommodating portion 2). As the platen roller 5 of the processing unit 3 rotates, the continuous paper 1 is sequentially fed out from the roll body 1 a and supplied to the processing unit 3.

  The roll body 1a is in a freely movable state in the space of the roll body housing part 2 with almost no restriction. Therefore, when the continuous paper 1 fed from the roll body 1a is conveyed while being pulled by the platen roller 5 provided in the processing unit 3, the roll body 1a is randomly generated in the roll container 2 by the pulling force. There is a possibility to move. In particular, in the configuration shown in FIG. 19, since the processing unit 3 is located above the roll body storage unit 2, the roll body 1 a may be lifted upward when the continuous paper 1 is conveyed. The roll body 1a does not stably stand still in the lifted state, and exhibits an irregular operation in the roll body housing portion 2. In particular, when the continuous paper 1 is intermittently conveyed, the roll body 1a is lifted when the continuous paper 1 is conveyed (when the continuous paper 1 is pulled upward), and when the conveyance of the continuous paper 1 is stopped ( When the continuous paper 1 is not pulled), the roll body 1a falls on the bottom surface of the roll body housing portion 2 due to gravity. When the roll body 1a is repeatedly lifted and dropped in this manner, an irregular large movement of the roll body 1a occurs. As a result, the continuous paper 1 cannot be accurately supplied to the processing unit 3, and malfunctions such as being conveyed while being inclined, the conveyance speed becoming uneven, and eventually being impossible to convey. Arise. Then, there is a possibility that an abnormality in processing by the processing head 4 of the processing unit 3, for example, printing failure, variation in thermal activation, or missing may occur.

  In addition, a sensor 18 that detects the size of the roll body 1a by detecting a part of the roll body 1a, that is, the remaining amount of paper, may be provided in the roll body housing portion 2. In such a case, when the roll body 1a exhibits an irregular operation such as being lifted as described above in the roll body accommodating portion 2, and temporarily deviates from the detection area of the sensor 18, the roll body 1a Regardless of the size, there is a possibility of misjudging that the remaining amount of paper is low.

  In view of the above, an object of the present invention is to provide an irregular movement such that the roll body is lifted by continuous paper fed from the roll body, even if the roll body is very easily set in the roll body accommodating portion. It is an object of the present invention to provide a continuous paper processing apparatus and a continuous paper processing method that can be stably conveyed without causing the occurrence of the problem.

  The continuous paper processing apparatus of the present invention includes a roll body housing portion that houses a roll body on which continuous paper is wound, and a position above the roll body housing portion and directly above the central axis of the roll body housed in the roll body housing portion. It is arranged at a position shifted in the horizontal direction from the corresponding position, and is disposed between the processing unit that performs processing on the continuous paper fed out from the roll body, and between the roll body storage unit and the processing unit, and is fed out from the roll body. A guide member that guides the continuous paper, and the guide member has an engaging portion that engages with the continuous paper fed from the roll body, and at least a part of the engaging portion is accommodated in the roll body accommodating portion. The roll body is disposed above and at a position opposite to the processing unit with respect to the central axis of the roll body.

  According to this configuration, when the roll body is accommodated in the roll body accommodating portion, no special positioning or mounting work is required, and the roll body can be easily set simply by being thrown into the roll body accommodating portion. When the processing unit located above the roll body container pulls and conveys the continuous paper fed from the roll body, there is no movement such as lifting the roll body.

  In particular, the engaging portion once leads the continuous paper fed from the roll body accommodated in the roll body accommodating portion to the side opposite to the processing portion with respect to the straight line connecting the feeding portion of the roll body and the processing portion. It is preferable to arrange in the position. In addition, the feeding part of a roll body said here means the part from which continuous paper leaves | separates from a roll body. In the present invention, since the guide member is present, there is a possibility that the position of the feeding portion of the roll body slightly differs from the case where the conveyance path for supplying continuous paper linearly from the roll body to the processing unit is configured. Preferably, the engaging portion is any of a straight line connecting the extended portion of the roll body when the guide member is present and the processing portion, and a straight line connecting the extended portion of the roll body when the guide member is not present and the processing portion. In contrast, the continuous paper is once arranged on the opposite side to the processing unit.

  It is preferable that the engaging part is located on the opposite side of the processing part from the outermost end of the roll body accommodated in the roll body accommodating part.

  In this case, when the engaging portion is located on the opposite side of the processing portion from the outermost end of the largest size roll body that can be accommodated in the roll body accommodating portion, the action of the present invention is always ensured. An effect can be obtained. However, problems such as the roll body being lifted mainly occur in a state where the roll body is relatively small. Therefore, the roll body with a size that is assumed to cause such a problem is used as a reference. You may make it the structure by which the engaging part is located in the side opposite to a process part rather than the outermost end of a body.

  You may have the cutter part which can cut | disconnect the continuous paper drawn | fed out from the roll body in the downstream of a process part.

  The processing unit includes a processing head that performs processing on the continuous paper fed from the roll body, and a platen roller that is disposed to face the processing head and conveys the continuous paper. The processing unit may be a printing unit that performs printing on the continuous paper fed from the roll body. Alternatively, the processing unit may be a heat activation unit that heats and heats the continuous paper fed from the roll body.

  Another feature of the present invention is that the continuous paper is fed out from the roll body accommodated in the roll body accommodating portion, and the central axis of the roll body accommodated in the roll body accommodating portion is located above the roll body accommodating portion. In a continuous paper processing method that leads to a processing unit arranged in a position shifted in the horizontal direction from a position directly above and processes the continuous paper by the processing unit, the continuous fed out from the roll body stored in the roll body storage unit After the paper is once guided to the opposite side of the processing unit with respect to the straight line connecting the feeding portion of the roll body and the processing unit by the engaging portion of the guide member located between the roll body containing unit and the processing unit, the processing is performed. It is to convey so that it may guide to a part.

  You may cut | disconnect the continuous paper processed by the process part with the cutter part located in the downstream of a process part.

  Printing may be performed on continuous paper fed from the roll body by the processing unit. Alternatively, the continuous paper fed from the roll body may be heated and thermally activated by the processing unit.

  According to the present invention, even when the roll body is configured to be easily set by simply inserting it into the roll body accommodating portion, the roll body may be lifted when the continuous paper fed from the roll body is transported. And can be transported satisfactorily.

  Embodiments of the present invention will be described below with reference to the drawings.

[Configuration of continuous paper processing equipment]
1 and 2 show the internal configuration of the continuous paper processing apparatus of the present invention. FIG. 1 shows a state in which a roll body 1a formed by winding the continuous paper 1 is accommodated in FIG. Each of these is shown in FIG. This continuous paper processing apparatus includes a roll body accommodating portion 2 that accommodates a roll body 1a, and a roll body accommodated in the upper side and the side of the roll body accommodating portion 2 (the right side in FIGS. And a processing unit 3 at a position P ₃ (a position shifted in the horizontal direction from the position P ₃ (see FIG. 3B)) immediately above the central axis of the body 1a.

  The roll body accommodating portion 2 has a pair of inclined surfaces 2a that form a substantially V-shaped cross section and support the outermost peripheral surface of the roll body 1a. The pair of inclined surfaces 2a are respectively in line contact with the outermost peripheral surface of the roll body 1a (point contact in a sectional view as shown in FIG. 1), whereby the roll body 1a is supported. In this structure, the center of the roll body 1a accommodated in the roll body accommodating part 2 and the center of the roll body accommodating part 2 are located on the same straight line. In other words, at least the position of the center of the roll body accommodating portion 2 and the center of the roll body 1a substantially coincides with the position in the width direction of the apparatus (left and right direction in FIGS. A sensor 18 that detects the remaining amount of the roll body 1a is provided inside the roll body housing portion 2.

  The processing unit 3 includes a processing head 4 and a platen roller 5 positioned to face the processing head 4. Between the processing head 4 and the platen roller 5, the continuous paper 1 to be processed according to the present invention is sandwiched. The platen roller 5 presses and supports the continuous paper 1 against the processing head 4, and sequentially feeds the continuous paper 1 by being driven by a driving means (not shown) and rotating. The processing head 4 performs processing on the continuous paper 1 supported by the platen roller 5. As an example, a recording head for recording on a continuous paper having a recordable surface or a heat-sensitive adhesive surface is used. It is a heat activation head which heats the continuous paper which has and expresses adhesiveness. A cutter unit is provided on the downstream side of the processing head 4 and the platen roller 5, and a discharge port 7 to the outside is provided on the downstream side. The cutter part of this embodiment consists of a movable blade and a fixed blade 6 facing the movable blade (not shown). The continuous paper 1 can be cut by moving the movable blade toward the fixed blade 6. 1 and 2, the movable blade is in the retracted position and is not shown in the drawings.

  This continuous paper processing apparatus is provided with a lid 8, which can be opened and closed with respect to the frame 17 by swinging about a shaft 9. The platen roller 5 and the fixed blade 6 of the cutter unit are attached to the lid 8 via a support member 10 and move integrally with the lid 8.

  A guide plate (guide member) 11 is attached to the lid 8 via an arm 12. The arm 12 is attached to the first protrusion 8 a provided on the lid 8 so as to be swingable about the shaft 13. Further, a link arm 14 is attached between the arm 12 and a second protrusion 8 b provided on the lid 8. The link arm 14 can swing with respect to the arm 12 about a shaft 15 (see FIG. 4B), and can swing with respect to the lid 8 about the shaft 16. By such an arm 12 and link arm 14, the guide plate 11 can move independently of the lid 8 within a certain range of movement. Although not shown, a spring is stretched between the arm 12 and a part of the lid 8. As shown in the perspective view of FIG. 4A and the like, the arm 12 and the link arm 14 and the protrusions 8a and 8b described above are provided on both sides of the lid 8, respectively. A guide plate 11 is attached so as to be spanned between the first link arms 12 positioned at the position.

  The link arm 14 is provided with a protrusion 14 a, and a cam 17 a is provided on the inner surface of the frame 17. In addition, the arm 12 is provided with a protrusion 12 a, and a guide groove 17 b is provided on the inner surface of the frame 17. Accordingly, when the projection 14a comes into contact with the cam 17a during the operation of closing the lid 8 as will be described later, the link arm 14 is pushed to resist the spring force of a spring (not shown), and the link arm 14 and the arm 12 and The guide plate 11 is moved as an operation independent of the movement of the lid 8 or as an operation combining the opening / closing operation of the lid 8 and the movement relative to the lid 8. Further, this movement is regularly performed by the projection 12a of the arm 12 sliding in the guide groove 17b.

  As shown in FIGS. 1 and 2, when the lid 8 is closed, the end of the guide plate 11 is biased to the side opposite to the processing unit 3 (left side in FIGS. 1 and 2). At least this end portion acts as an engaging portion 11 a that engages with the continuous paper 1.

Here, considering the conveyance path of continuous paper, if the guide plate 11 does not exist, the conveyance path of continuous paper is along the straight line L ₁ connecting the feeding portion of the roll body 1 a and the processing unit 3. It is formed. In contrast, in the configuration of the present embodiment, as shown in FIG. 1, the engagement portion 11a of the guide plate 11, the straight line L ₁ described above, the processing unit 3 and the opposite side (left side in FIG. 1 and 2) A transport path is formed in which the continuous paper 1 is once guided and then guided to the processing unit 3. Strictly speaking, when the guide plate 11 is present, the position of the extended portion of the roll body 1a slightly moves, and the straight line L ₂ connecting the extended portion of the roll body 1a and the processing unit 3 in that case is , Slightly different from the straight line L ₁ . Engaging section 11a, for any of the lines L ₁ and the straight line L _2, the processing unit 3 and the opposite side (left side in FIGS. 1 and 2), are arranged to direct the continuous sheet 1 temporarily.

  In the present embodiment, the bottom surface portion provided with the inclined surface 2 a that supports the roll body 1 a is also provided connected to the lid 8. Although not described in detail, a panel 19 including a display unit and an input unit is disposed outside the frame 17.

[Outline of continuous paper processing method]
The outline of the processing operation by the continuous paper processing apparatus will be described. First, the roll body 1a is set in the continuous paper processing apparatus. For this setting operation, it is only necessary to put the roll body 1a into the space of the roll body housing portion 2. At this time, one end of the continuous paper 1 is pulled out from the roll body 1a and the processing head 4 and the platen of the processing section 3 are pulled out. The lid 8 is closed while being sandwiched between the rollers 5. At this time, after the continuous paper 1 drawn out from the roll body 1a is once guided to the opposite side (left side in FIGS. 1 and 2) from the processing unit 3 by the engaging portion 11a of the guide plate 11, as described above. 1 and 2 are guided to the processing unit 3 located on the right side of FIGS.

  In this state, when a driving signal is sent from the control means (not shown) to the processing head 4, the processing head 4 processes the continuous paper 1, and the platen roller 5 is rotated by the driving means (not shown). The continuous paper 1 is conveyed. By synchronizing the operation of the processing head 4 and the operation of the platen roller 5, the continuous paper 1 is sequentially processed. The processing head 4 may be a thermal head or the like, and thermal activation is performed by printing on the continuous paper 1 or heating the heat-sensitive adhesive layer provided on the continuous paper 1. When the processing of the continuous paper 1 having a predetermined length is completed, the conveyance of the continuous paper 1 is stopped, and the movable blade (not shown) of the cutter unit moves toward the fixed unit 6 so that the processed continuous paper 1 is processed. Disconnect. When the continuous paper 1 is subsequently processed, the transport of the continuous paper 1 by the platen roller 5 and the processing by the processing head 4 are performed again, and the transport of the continuous paper 1 is stopped and cut.

  As described above, even when the continuous paper 1 is intermittently conveyed by the rotation of the platen roller 5, according to the present embodiment, the roll body hardly moves and only the rotation is performed. Can be transported.

[Consideration of the transport state of continuous paper]
As described above, the reason why the continuous paper 1 can be stably conveyed according to the present embodiment will be considered below.

  In the conventional configuration in which the guide plate 11 does not exist, the reason for the irregular movement such as the roll body 1a being lifted as the continuous paper 1 is transported is as shown in FIG. Since the force of the platen roller 5 of the processing unit 3 positioned above the body storage unit 2 to rotate and transport the continuous paper 1 mainly works in the direction of lifting the roll body 1a against gravity. That is, it is considered that the component of the upward force in the vertical direction is large. When the roll body 1a is lifted, when the rotation of the platen roller 5 is stopped and the conveyance of the continuous paper 1 is temporarily stopped at the time of cutting the continuous paper, the force to lift the roll body 1a is lost, and the roll body 1a is caused by gravity. Falls. Such a roll body 1a is repeatedly raised and dropped and the position of the roll body 1a is not stable, and the roll body 1a is inclined in the longitudinal direction due to the rise and fall of the roll body 1a and the impact and reaction of the fall. As a result, the roll body 1a is not stably held. As a result, it becomes impossible to continue a good conveyance state of continuous paper, and processing failure (for example, printing failure, variation in thermal activation, etc.) occurs. Further, when the roll body 1a is temporarily lifted, it may be out of the detection range of the sensor 18 and erroneously determined that the remaining amount of the continuous paper 1 is insufficient even though the remaining amount of the continuous paper 1 is sufficient. There is sex.

  On the other hand, in this embodiment, as schematically shown in FIG. 3B, the platen roller 5 of the processing unit 3 positioned above the roll body storage unit 2 rotates to convey the continuous paper 1. The force to act as a force that pulls the continuous paper 1 from the portion engaged by the engaging portion 11a of the guide plate 11 in the substantially horizontal direction, and lifts the roll body 1a against gravity (vertical direction). (Upward) hardly works. Therefore, the roll body 1a is not lifted by the force for conveying the continuous paper 1. In addition, although the conveyance path between the engaging part 11a and the feeding part of the roll body 1a has an obtuse angle close to the vertical direction, the part where the continuous paper 1 is engaged with the engaging part 11a of the guide plate 11 However, it is conceivable that the transfer force due to the rotation of the platen roller 5 acts as a buffer during transmission to the roll body 1a. Therefore, an abrupt and strong force that lifts the roll body 1a against gravity is not transmitted to the roll body 1a.

  Moreover, in the present embodiment, the portion of the continuous paper 1 that is engaged with the engaging portion 11a of the guide plate 11 is located on the opposite side to the processing portion 3 (left side in FIGS. 1 to 3). For this reason, the continuous paper 1 is in a state of being tightly tensioned in the engaging portion at all times in the horizontal direction. Therefore, there is no play that allows the roll body 1a to bounce up and down. For these reasons, in this embodiment, it is considered that the roll body 1a is hardly lifted as the continuous paper 1 is conveyed. Since the roll body 1a is not lifted, it is natural that the roll body 1a does not drop due to gravity when the conveyance of the continuous paper 1 is stopped. It is also possible to prevent the sensor 18 from making an erroneous determination. In addition, in this embodiment, since the roll body 1a is hold | maintained at the substantially V-shaped part comprised by one pair of inclined surfaces 2a, it moves almost also in a horizontal direction (left-right direction of FIGS. 1-3). do not do.

  Further, in the present embodiment, in the processing unit 3, the continuous paper 1 is once moved upward by a slight distance, and then reaches the space between the processing unit 3 and the platen roller 5 to be conveyed in the horizontal direction. Yes. It is also considered that the portion of the continuous paper 1 that is directed upward by a small distance has a buffering action with respect to transmission of the conveyance force. Thus, between the force transmission path (the path that coincides with the transport path of the continuous paper 1) from the part that generates the transport force (the platen roller 5) to the part that may move (the roll body 1a), It is considered that the more the direction changing portions, the greater the impact absorbing and buffering effects, and the more rapid and irregular movement of the roll body 1a can be suppressed. In this sense, in this embodiment, since there are more direction change portions than in the conventional case, it is possible to prevent an undesirable movement such as a rise of the roll body.

Or more for obtaining the advantages of the present invention as described, when viewed in the horizontal direction (lateral direction in FIG. 3 (b)), the position P ₁ of the engaging portion 11a of the guide plate 11, at least, the roll body 1a with respect to the position P ₃ corresponding to directly above the central axis, the processing unit 3 must be located on the side of position (right side in the figure) and the opposite side (left side in the drawing). And, preferably, the engaging portion 11a, to the position P ₂ of the outermost end of the roll body 1a, the processing unit 3 is arranged offset to the side of position (right side in the figure) and the opposite side (left side in the drawing) . By maintaining such a positional relationship, a path when the continuous paper 1 is linearly conveyed from the roll body 1a to the processing unit 3 by the engaging portion 11a of the guide plate 11 (FIG. 3A). In contrast, a conveyance path is formed that is once guided to the side opposite to the processing unit 3 (left side in the drawing) and then turned again to the processing unit 3. As a result, as described above, the roll body 1a is stably held without being raised and dropped, and good conveyance can be performed.

[Cover opening and closing operation]
Next, the opening / closing operation | movement of the lid | cover 8 in this embodiment is demonstrated with reference to FIGS. Here, the operation of closing the lid 8 from the opened state will be described. 4 and 6 to 11, (a) is a perspective view in which the roll body 1 a is omitted, (b) is a cross-sectional view in which the roll body 1 a is omitted, and (c) is a cross-sectional view including the roll body 1 a. is there.

  4A to 4C show a state where the lid 8 is completely opened. In this state, the arm 12 is integrally open with the lid 8 by the spring force of a spring (not shown). Therefore, the roll body 1 a is inserted inside the lid 8. At this time, the roll body 1a is held relatively stably by one of the inclined surfaces 2a of the bottom surface portion connected to the lid 8 (the one on the right side of the drawing) and the inclined surface 8c provided on the lid 8. (See FIG. 4C).

  Next, the lid 8 starts to close. Then, the projection 14 a of the link arm 14 is pressed against the cam 17 a of the frame 17. FIG. 5A shows the state at the start of contact, and an A portion in FIG. 5A is enlarged and shown in FIG. 5B. Further, in order to make the positions and shapes of the protrusion 14a and the cam 17a easy to understand, an exploded perspective view is shown in FIG. When the projection 14a of the link arm 14 is pressed against the cam 17a, the link arm 14 is centered on the shaft 16 (see FIG. 4B) as shown in FIGS. 6 (a) to 6 (c). Swings relative to the lid 8. As the link arm 14 swings, the arm 12 connected to the link arm 14 via the shaft 15 swings with respect to the lid 8 about the shaft 13. This swing is a movement in which the arm 12 and the guide plate 11 are closed toward the frame 17 before the lid 8. Thus, in this embodiment, the arm 12 and the link arm 14 constitute a link mechanism.

  When the lid 8 itself is closed toward the frame 17 in a state where the projection 14a of the link arm 14 is in contact with the cam 17a, the arm 12 and the guide plate 11 are, as shown in order in FIGS. Prior to the lid 8, it enters the back of the frame 17 (left side of the drawing). At this time, as shown in FIG. 8 (c), the guide plate 11 is provided under the continuous paper 1 fed from the roll body 1a, that is, the roll body 1a and the continuous paper 1 fed from the roll body. Enter between. Further, as shown in FIGS. 8A to 8C, the protruding portion 12 a of the arm enters the guide groove 17 b of the frame 17. Since the guide groove 17b is wide on the opening side (the right side in the drawing), the protrusion 12a of the arm 12 can easily enter. Moreover, since the guide groove 17b is tapered toward the back side (the left side in the drawing), the movement path of the protrusion 12a is gradually regulated, and the arm 12 is finally accurately positioned at a predetermined position. Led. Then, as shown in FIGS. 9 (a) to 9 (c), after the guide plate 11 reaches above the central axis of the roll body 1a, the guide plate 11 is further moved to obtain FIGS. 10 (a) to 10 (c). As shown, the guide plate 11 reaches the back side (the side opposite to the processing unit 3) from the central axis of the roll body 1a. Finally, as shown in FIGS. 11A to 11C, the lid 8 is completely closed.

  Note that the opening operation from the closed state of the lid 8 is performed in exactly the reverse manner as described above, that is, from the states of FIGS. 11 (a) to 11 (c), FIGS. 10 (a) to 10 (c). ) State, FIGS. 9A to 9C state, FIGS. 8A to 8C state, FIGS. 7A to 7C state, and FIGS. The state shifts in turn to the state of (c), the state of FIGS. 4 (a) to 4 (c). In this case, when the lid 8 is opened, the projection 14a of the link arm 14 abuts against the cam 17a and the movement is restricted. Therefore, the guide plate 11 and the arm 12 are opened after the movement of the lid 8. Go.

In the present embodiment, as shown in FIGS. 1 to 3 and 11, the position P ₁ of the end portion of the engaging portion 11 a of the guide plate 11 is directly above the central axis of the roll body 1 a with the lid 8 closed. It is located on the side opposite to the processing unit 3 (left side in the drawing) with respect to the position P ₃ (same as the center of the roll body housing unit 2). If the guide plate 11 is fixed in such a position, the end of the continuous paper 1 fed out from the roll body 1a when the lid 8 is opened and the roll body 1a is put into the roll body housing portion 2 is assumed. It is very difficult to set the part so as to guide the part through the upper part of the guide plate 11 to the processing part 3. That is, the end of the continuous paper 1 fed out from the roll body 1a is placed between the roll body 1a and the upper wall of the frame 17 in a very narrow work space as can be seen from FIG. Passing through a narrow space requires very precise work and is extremely difficult.

  If the cover 8 is configured to open widely to nearly 180 degrees, before inserting the roll body 1a into the roll body housing part 2, the end of the continuous paper 1 is secured with a relatively wide working space secured. It is conceivable that the work passing through the guide plate 11 can be performed and workability is improved. However, as in the present embodiment, in the configuration in which the processing unit 3 is positioned above the roll body housing unit 2 and the lid 8 swings around the shaft 9 positioned at the lower part of the frame 17, this apparatus is opened and closed. The lid cannot be widened more than 90 degrees with the surface remaining on the plane. Therefore, it is necessary to open the lid 8 in a state where the apparatus is tilted, which is not preferable because it becomes a product that is practically very difficult to use.

In consideration of these circumstances, the applicant of the present invention, with the guide plate 11 in the state where the lid 8 is opened, against P ₃ which is directly above the central axis of the roll body 1a as shown in FIGS. It was considered that it is preferable to escape from the frame 17 in the same manner as the lid 8, not at the position opposite to the processing unit 3 (left side in the drawing). In the present invention, the guide plate 11 is configured to be movable as an operation independent from the lid 8 or as an operation combining the opening / closing operation of the lid 8 and the movement relative to the lid 8. When the roll body 1a is inserted into the roll body housing portion 2 and the lid 8 is closed, the end of the continuous paper 1 fed out from the roll body 1a is positioned above the guide plate 11, and the guide plate 11 is moved. The configuration for moving to the position P ₁ on the opposite side (left side of the drawing) from the processing unit 3 was realized for the first time. In particular, in the above-described embodiment, by configuring a link mechanism including the arm 12 and the link arm 14, the guide plate 11 combines opening / closing operation of the lid 8 and swinging relative to the lid 8. It became possible to move as an action. As a result, when the lid 8 is open, the roll body 1a is inserted into the roll body housing portion 2 with the end of the continuous paper 1 being pulled out, and the lid 8 is simply closed. The guide plate 11 can be disposed on the guide plate 11 and moved to a desired position P ₁ . It is not necessary for the user to pass the continuous paper 1 through a narrow space between the guide plate 11 and the upper wall of the frame 17, and it is not necessary to directly move the guide plate 11 itself, and the roll body 1a is simply inserted. Since the work only needs to be closed, the workability is very good. As is clear from FIGS. 4A to 4C, these operations are sufficiently possible even when the opening angle of the lid 8 is less than 90 degrees. Can be configured practically and easy to use.

  As an additional effect of the present embodiment, as shown in FIGS. 4 and 12, when the lid 8 is opened, the fixed blade 6 of the cutter part is covered with the guide plate 11 and is not exposed to the outside. It is mentioned that there is no possibility that a person etc. will touch the fixed blade 6 accidentally.

[Other Embodiments]
Next, another embodiment of the present invention will be described with reference to FIGS. 13 to 14 show the internal configuration of the continuous paper processing apparatus according to the second embodiment of the present invention. FIG. 13 shows a state in which a roll body 1a formed by winding the continuous paper 1 is accommodated in FIG. The state in which the roll body 1a is not accommodated is shown in FIG.

  The continuous paper processing apparatus of the present embodiment does not include the link arm 14, the connecting shafts 15 and 16, the cam 17a, and the guide groove 17b. A spring (not shown) urges the arm 12 to approach the frame 17 side. That is, the direction of the biasing force applied by the spring to the arm 12 is substantially opposite to that of the first embodiment. Since the configuration other than these is the same as that of the first embodiment shown in FIGS.

Also in this embodiment, as shown in FIG. 13, the position P ₁ of the engaging portion 11a of the guide plate 11 is opposite to the processing portion 3 with respect to the position P ₃ just above the central axis of the roll body 1a (drawing). It is located on the left side. Then, with this guide plate 11, the continuous paper 1 is temporarily placed on the side opposite to the processing unit 3 (left side in FIG. 13) from the straight lines L ₁ and L ₂ connecting the feeding portion of the roll body 1a and the processing unit 3. A conveyance path is configured so as to guide and then to the processing unit 3.

  In the present embodiment, the guide plate 11 and the arm 12 are configured to be manually moved without being interlocked with the opening / closing operation of the lid 8. Here, the operation of opening the lid 8 and setting the roll body 1a from the state in which the lid 8 is closed as shown in FIGS.

  First, when the lid 8 is opened from the state shown in FIG. 15, the guide plate 11 and the arm 12 remain on the back side of the frame (left side of the drawing) as shown in FIG. Become. In this state, since the guide plate 11 is in the way and the roll body 1a cannot be taken in and out, as shown in FIG. 17 (a), the user manually opposes the guide plate 11 and the arm 12 against the spring force. Pull out to the outside of the frame 17. Note that FIG. 17B shows a state in which the guide plate 11 and the arm 12 are manually pulled out so as to be close to the lid 8 at an angle different from that in FIG.

  After the roll body 1a is inserted into the roll body housing portion 2 in this state, when the hand is released from the guide plate 11 and the arm 12, the guide plate 11 and the arm 12 are moved to the back side of the frame by the biasing force of a spring (not shown). Move to the left side of the drawing. However, since the relative movement angle of the arm 12 with respect to the lid 8 is limited by the stopper 20, as shown in FIGS. 18 (a) and 18 (b), the guide plate 11 is just before entering the inside of the frame 17. Stop. 18A is a perspective view, FIG. 18B is a sectional view in which the roll body 1a is omitted, and FIG. 18C shows the frame 17 in which the guide plate 11 is biased by a spring (not shown). The state which moved to the side is shown by the angle different from Fig.18 (a).

Finally, when the lid 8 is closed, the guide plate 11 and the arm 12 move together to enter the inner side of the frame 17, and the state shown in FIGS. Note that the relative movement angle of the arm 12 with respect to the lid 8 by the stopper 20 is limited when the engaging portion 11a of the guide plate 11 is in a state where the lid 8 is completely closed as shown in FIGS. It is set to stop at a desired position P ₁ .

  Also in this embodiment, the same effect as the first embodiment described above can be obtained. However, since the guide plate 11 and the arm 12 must be moved manually, the work can be a little complicated, but the link arm 14 and the cam 17a are not necessary, and the configuration can be simplified.

In the two embodiments described above, the guide plate 14 is attached to the lid 8 via the arm 12, but the guide plate 14 can swing with respect to the frame 17 via the arm 12 or other members. It can also be an installed configuration. In that case, the guide plate 11 and the arm 12 are manually moved in the same manner as in the second embodiment, rather than the configuration in which the guide plate 11 and the arm 12 are automatically moved in conjunction with the opening and closing of the lid 8 as in the first embodiment. Is easier to implement. In any case, the guide plate 14 is operated at a predetermined position P ₁ as an operation independent of the opening / closing of the lid 8 or an operation combining the opening / closing operation of the lid 8 and the movement relative to the lid 8. And the outside of the frame 17 can achieve the same effects as described above.
