[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a configuration of a laminating apparatus for covering and bonding front and back surfaces of a laminate such as paper with a synthetic resin sheet.
[0002]
[Prior art]
Conventionally, a laminating apparatus for laminating a card or the like with a sheet such as a synthetic resin film is known.
[0003]
In Japanese Patent Application Laid-Open No. 10-507005 as an example, a pair of sheet rolls, each of which is formed by winding a pair of sheets for laminating the front and back surfaces of a sheet, are rotatably supported at respective vertical positions in a sheet cassette. The sheet cassette can be detachably mounted on the sheet supply unit of the apparatus main body.
[0004]
In the apparatus main body, a pair of upper and lower sandwiching rollers are disposed on the sheet discharge side of the sheet cassette, and both the sandwiching rollers rotate in synchronization with the rotation of the outer handle.
[0005]
Then, the sheet placed on the sheet feeding tray is supplied while being brought close to the upper and lower sheet rolls, and the upper and lower sheets are pulled out by the sandwiching roller, and the sheet is sandwiched and laminated between them. In this case, an adhesive layer is provided on one side (clamping surface) of the sheet. When the laminated body formed in this manner is cut in the X direction (direction perpendicular to the paper conveyance direction) with a horizontal cutter blade, paper (laminate) laminated with a sheet of PET film or the like is obtained. It was.
[0006]
[Problems to be solved by the invention]
However, in the conventional apparatus, both sheets drawn from the outer periphery of the upper and lower sheet rolls on the side close to the sheet conveyance path between the rotation centers of the upper and lower sheet rolls are directly sandwiched between the nipping roller portions. Since the sheet is fed to the nipping position, the nipping angle between the sheet and the sheet by the pair of nipping rollers (the straight line connecting the outer periphery of each sheet roll and the nipping side outer periphery of the nipping roller, and the sheet conveyance path) Is small when the sheet winding diameter of the sheet roll is large, and increases as the sheet winding diameter decreases.
[0007]
By the way, when the sandwiching angle between the sheet to be laminated and the paper to be laminated is different, the laminating action is also different. In other words, if the pinching angle is small, the adhesive layer of the sheet adheres to the surface of the paper considerably before the pinching point by the pair of pinching rollers (upstream side in the paper conveyance direction), and the actual position of the pinching roller pair In this case, the sheet and the paper are bonded to each other before the clamping pressure is applied, and the sheet or the paper is wrinkled at the time of lamination, or air is entrained to generate air bubbles between the sheet and the paper.
[0008]
On the other hand, if the sandwiching angle is too large, such as about 90 degrees, there is a problem that the resistance to pulling out the sheet from the sheet roll increases and the laminating operation becomes heavy. Such a problem becomes conspicuous in a sheet roll for laminating a sheet having a large winding diameter, in other words, a large sheet.
[0009]
The present invention has been made in order to solve the above-mentioned problems of the prior art, and can always keep the laminating action substantially constant regardless of the winding diameter of the sheet roll, and can also be used for sheets of different sizes. An object of the present invention is to provide a laminating apparatus capable of laminating (laminated object).
[0010]
[Means for Solving the Problems]
And the laminating device of the invention according to claim 1 for solving the above-mentioned problem is a laminate supply section for supplying the laminate, and a pair of upper and lower sheet rolls in which the sheet is wound in a roll shape. detachably mounted, vertically a sheet supply unit for supplying sheets from the pair of upper and lower sheet rolls, the said object laminate supplied from the laminate feeding part, and a sheet fed from the sheet feeding unit Each of the laminating sections that are sent out as a laminate while being laminated and bonded by a pair of sandwiching rollers, and disposed between the pair of upper and lower sandwiching rollers and the pair of upper and lower sheet rolls, and supplied from the pair of upper and lower sheet rolls in laminating apparatus and a sheet guide portion of the upper and lower pair of sliding contact with the sheet, the roll center position of each sheet roll, the clamping of the nip roller It is arranged at a position away from the extended line in the sheet drawing direction connecting the side outer peripheral surface and the sliding contact portion of each sheet guide portion in the vertical direction, and from the sheet guide portion as the initial winding diameter increases.

[0015]
In the figure, a laminating apparatus 1 according to an embodiment of the present invention is covered with an exterior body 1a as shown in FIGS. 1 and 2, and the inside is similar to the configuration of the prior art, with a sheet supply unit A and a sheet supply unit B being included. , A laminating unit C, and a cutting unit D.
[0016]
The basic functions of each component are the same as in the prior art. The paper supply unit A is a part that supplies paper P such as documents and cards, and the sheet supply unit B is a sheet for laminating the paper P. This is a portion for supplying S1 and S2. The laminating unit C is a part for laminating the paper P supplied from the paper supply unit A between the sheets S1 and S2. Furthermore, the cutting part D is a part which cuts the laminated body R sent out from the lamination processing part C, and cuts the laminated body R in the X direction shown in FIG. 1 by a transverse cutting mechanism (not shown) as a cutter means. The longitudinal cutting mechanism 42 has a function of cutting the laminate R in the Y direction shown in FIG.
[0017]
As shown in FIG. 1, the paper feed tray 11 disposed in the paper supply unit A as the stack supply unit on the upper left side of the exterior body 1 a can be detached from the exterior body 1 a or folded when not in use. You may comprise.
[0018]
The paper feed tray 11 has a flat paper placement surface on which the paper P to be stacked is placed, and is provided with paper guides 12a and 12b for positioning the paper P in the width direction. At least one of the paper guides 12a and 12b is movable and supported so as to be movable in the X direction, and arbitrarily adjusts the distance from the wall surface of the exterior body 1a. In the present embodiment, it is assumed that sheet cassettes 20 of various sizes, which will be described later, are arranged so as to be laminated with reference to the right side of the paper P (the right side when viewed from the paper P discharge side).
[0019]
A paper feed roller is provided between the base end side of the paper feed tray 11 and the front side (stacked product introduction side) of the sheet cassette 20 that is detachably mounted on the cassette storage unit 4 having an open top surface in the sheet supply unit B. A pair of paper feed rollers 8a and 8b as means is arranged so as to be separated and approached to the stacked product (paper P) introduction side of the sheet cassette 20 via a swing mechanism 3 as an interlocking portion described later. (See FIGS. 2 to 4).
[0020]
The sheet cassette 20 detachably attached to the cassette storage unit 4 and an attachment 60 described later has two sheet rolls 21 and 22 built in a vertical position in the housing 23 as representatively shown in FIG. Is.
[0021]
By the way, the laminating apparatus 1 of the present embodiment is configured so that the sheet rolls 21 of the sheets S1 and S2 having widths corresponding to the respective sizes can be laminated so that three types of paper P, A3, A4, and A6, can be laminated. A sheet cassette 20 including a housing 23 having a different size in which 22 is accommodated is configured to be detachable. In the following, for the reference numeral 23a (see FIG. 5 and FIG. 6) for the A3 size housing, 23b for the A4 size housing (see FIG. 8 and FIG. 10), and for the A6 size housing 23c (see FIGS. 9 and 11).
[0022]
The casing 23 employed in the present embodiment is made by injection molding of a synthetic resin material such as polypropylene resin, and is composed of a pair of front and rear cases 27a and 27b, and the ends thereof are fitted to each other. An integral housing 23 is configured.
[0023]
Among the openings provided in the housing 23, the opening provided on the front side (upstream side of conveyance, stacking material introduction side) is a paper insertion port 27c, and is located on the back side (downstream side of conveyance, stacking material discharge side). ) Is a paper outlet 27d.
[0024]
The paper insertion opening 27c serves to feed the paper P between the supported sheet rolls 21 and 22. On the other hand, the paper delivery port 27d has a function of delivering the paper P fed from the paper insertion opening 27c to the laminating unit C together with the sheets S1 and S2 fed from the sheet rolls 21 and 22, respectively. A pair of upper and lower shutters 24 for opening and closing the paper outlet 27d is provided at the paper outlet 27d.
[0025]
In the housing 23, a pair of upper and lower guide plates 25a and 25b are provided in a positional relationship so as to extend from the paper insertion port 27c toward the paper delivery port 27d. The guide plates 25a and 25b form a guide path for guiding the paper P sent from the paper insertion opening 27c to the paper delivery outlet 27d. Here, in the present embodiment, the lengths of the guide plates 25a and 25b are not the same, the lower guide plate 25b is shorter, and the upper guide plate 25a is longer. A resin spring 26 is attached to the lower guide plate 25b to position the supplied paper P by pressing it against the upper guide plate 25a. Accordingly, the paper P fed from the paper insertion opening 27c is reliably guided to the paper delivery outlet 27d by the guide plates 25a and 25b and the resin spring 26.
[0026]
On the sheet pull-out side (sheet delivery outlet 27d side) from the pair of upper and lower sheet rolls 21, 22, there are upper and lower portions between the nipping portions 28 (see FIGS. 6 and 12) of the nipping rollers 31, 32. A pair of sheet guide portions 29a and 29b are arranged. Then, the sheets S1 and S2 drawn from the upper and lower sheet rolls 21 and 22 in the housing 23 of each sheet cassette 20 are drawn from the outer periphery away from the roll center positions 21a and 22a of the respective sheet rolls in the vertical direction. The upper and lower pair of sheet guide portions 29a and 29b are bent at the tip portions (sliding contact portions) and come into contact with the sandwiching outer peripheral surfaces of the sandwiching rollers 31 and 32. In such a case, the sheet guide portions 29a and 29b are located at positions that are separated from each other by a vertical line extending from a straight line (hereinafter referred to as sheet lead-out lines 50a and 50b) connecting the leading end portions (sliding contact portions) of the sheet guide portions 29a and 29b and the outer periphery of the holding roller. The roll center positions 21a and 22a of the sheet rolls 21 and 22 are arranged.
[0027]
With this configuration, even when the winding diameter is large, such as immediately after the start of use of each of the sheet rolls 21 and 22, by using the sheet, the outer circumferences of the reels 21b and 22b of the sheet rolls 21 and 22 are close to each other. Even when the winding diameter is reduced, the outer surfaces of the sheets S1 and S2 drawn from the outer periphery of each of the sheet rolls 21 and 22 are the tip portions (sliding contact portions) of the pair of upper and lower sheet guide portions 29a and 29b. The sheet is always slid and bent and is guided to the clamping portion 28 of the clamping rollers 31 and 32 along the sheet drawing lines 50a and 50b having a certain clamping angle θ1 and θ2.
[0028]
Therefore, regardless of the initial (first) winding diameter of the sheet rolls 21 and 22, and the change in the winding diameter due to the use of the sheet, the sandwiching angles θ1 and θ2 are constant, and the laminating action is constant. It is retained. As shown in FIG. 12, the roll center positions 21a and 22a of the sheet rolls 21 and 22 stored in the small A4 size casing 23b and the A6 size casing 23c are stored in the large A3 size casing 23a. The sheet rolls 21 and 22 are displaced from the roll center positions 21a and 22a toward the conveying downstream side so as to be closer to the sandwiching portion 28 and thus the upper and lower sheet guide portions 29a and 29b. In other words, the roll center positions 21a and 22a of the sheet rolls 21 and 22 stored in the large A3 size casing 23a are replaced with the sheet rolls stored in the small A4 size casing 23b and the A6 size casing 23c. They are arranged away from the upper and lower sheet guide portions 29a and 29b with respect to the roll center positions 21a and 22a of 21 and 22 and deviated to the upstream side of conveyance.
[0029]
For this purpose, an A4 size housing 23b or an A6 size housing 23c is placed on an attachment 60 as will be described later.
[0030]
With this configuration, the sheet cassette containing the sheet roll having the initial winding diameter and the sheet cassette containing the sheet roll having the initial winding diameter are arranged so as to generate the same laminating action. Can do.
[0031]
As shown in FIGS. 4, 7, 10, and 11, the attachment 60 has the same planar shape as the A3 size housing 23 a that completely fits into the cassette housing portion 4 that is open on the upper surface, and is smaller than this A4 size. The housing 23b and the A6 size housing 23c can be placed and set at predetermined positions. This will be described in more detail. The side cross-section of the bottom plate 60a on which the casing 23 is placed and the wall plate 60b standing from one side of the bottom plate 60a (in the embodiment, the upstream side of the conveyance of the paper P) is substantially reduced. It is formed in an L-shape, and a block portion 60c for positioning is formed to protrude upward at one end in the longitudinal direction of the bottom plate 60a and the wall plate 60b (in the embodiment, the right end of the paper P). The synthetic resin material is integrally formed by injection molding. The wall plate 60b and the block portion 60c are provided with support portions 60d and 60d for preventing the set casing 23 from falling to the upstream side of the conveyance of the paper P, and the bottom plate 60a has a guide recess. The locations 62 and the positioning projections 63 are formed in a recessed manner at a plurality of predetermined locations.
[0032]
The guide protrusions 61 projecting from the left and right end portions of the bottom surface of the housing 23 are fitted into guide recesses 62 that are formed in the bottoms of the cassette housing part 4 and the attachment 60 or are recessed. It's getting round. Further, a positioning projection 63 such as a truncated pyramid that protrudes from the bottom surface of the housing 23 is formed in the bottom of the cassette housing portion 4 and the attachment 60 or is fitted in a positioning recess 64 formed as a recess. (See FIGS. 4 to 10, FIGS. 8 and 9 are perspective views so that the housing 23b and the housing 23c can be seen).
[0033]
Incidentally, there is a demand for laminating sheets of sizes A3, A4, and A6, and in response to this, the width dimensions of the pair of upper and lower sheets S1 and S2 stored in the housing 23 of the sheet cassette 20 are different. Of course, assuming that the number of times that lamination is possible is almost the same regardless of the size, in order to laminate a large size sheet, the winding length of each sheet S1, S2 is long, and the winding diameter is long. growing. Therefore, the dimension of the casing 23 of the sheet cassette 20 along the stack conveyance direction (hereinafter referred to as the depth dimension) is generally large when the size is large, and is small when the size is small. It is.
[0034]
In this case, since the sheet cassette 20 must be detachably disposed between the pair of paper feed rollers and the pair of sandwiching rollers, the pair of paper feed rollers 8a and 8b and the pair of sandwiching rollers 31 and 32 as in the prior art. In the configuration in which is fixedly positioned, it is necessary to set the distance (inter-roller distance) from the pair of paper feed rollers 8a and 8b to the pair of sandwiching rollers 31 and 32 to be long. If it does so, there existed a problem that it became impossible to laminate with respect to a small sized paper.
[0035]
On the other hand, if the distance between the rollers is set short so that a small size can be laminated, it is necessary to reduce the winding diameter of the sheet rolls 21 and 22 to be stored in the sheet cassette 20, There is a problem in that the number of times that large-size paper P can be laminated is extremely reduced, and the frequency of replacement of the sheet cassette 20 or replacement of the sheet rolls 21 and 22 in the sheet cassette is increased.
[0036]
Therefore, in the case 23 for laminating the A3 size paper P, the size (depth size) in the transport direction of the paper P is increased, while the paper is inserted in the front case 27a as shown in FIGS. A recess 27e is formed by recessing the position of the opening 27c in the direction of the sheet delivery outlet 27d. When the sheet cassette 20 is set, the pair of paper feed rollers 8a and 8b is moved via the swing mechanism 3 as described later. When the small size (A4, A6) sheet cassette 20 enters the recess 27e, the distance between the rollers is shortened by approaching the sheet insertion opening 27c, while the sheet cassette 20 has a different size. However, it can be detachably attached to the same laminating apparatus.
[0037]
Therefore, when the A4 size housing 23b and the A6 size housing 23c are set so that the one end surface of the housing of the block portion 60c in the attachment 60 is in contact with each other (see FIGS. 10 and 11), The sheets S1 and S2 are sent out so that the right edge of the sheet P to be used becomes the reference side of the laminating operation.
[0038]
In the set state, a limit switch or the like in which detected portions 65 and 65 projecting from both end portions of one longitudinal side surface of each size of the casings 23a, 23b, and 23c are provided at predetermined positions of the laminating apparatus 1. The size of the paper P that can be laminated can be displayed on a display unit (not shown) such as a liquid crystal panel provided in the laminating apparatus 1 by detecting with a sensor (not shown). ing.
[0039]
The sheet rolls 21 and 22 are the same as the prior art in that long sheets are wound in a roll shape, but the materials themselves of the sheets S1 and S2 are greatly different from those of the prior art. That is, in FIG. 6, the sheet S1 wound around the sheet roll 21 disposed at the top of the figure has a transparent resin film layer as a base material, and an adhesive layer is laminated on one surface thereof. For example, a PET (polyethylene terephthalate) film is used as the film layer as the base material of the sheet S1.
[0040]
As shown in FIG. 6, the sheet S <b> 2 wound around the sheet roll 22 disposed below is a release sheet, and more specifically, a release paper. That is, the sheet S2 is made of paper and is impregnated or laminated with a releasable substance such as paraffin, and has such a property that it adheres to such an extent that the adhesive layer of the sheet S1 can be easily peeled off. Of course, the sheet S2 is not limited to a release sheet using paper as a base material, and may be a sheet using a resin having a release property as a base material.
[0041]
Each of the sheet rolls 21 and 22 described above is rotatably supported in the housing 23.
[0042]
Then, the sheets S1 and S2 are fed out from the paper outlet 27d of the housing 23 so that the adhesive surface and the release surface face each other.
[0043]
The sheet cassette 20 can be detachably mounted on the cassette storage section 4 in the laminating apparatus 1 or the attachment 60 that is detachably mounted on the cassette storage section 4. A large A3 size housing 23 a The A4 size housing 23b and the A6 size housing 23c are respectively placed on the bottom plate 60a of the attachment 60 with the bottom surface being placed on the bottom plate 4a of the cassette storage unit 4, respectively. 11 so that the paper P supplied from the paper 11 is smoothly fed into the sheet cassette 20, each paper insertion opening 27 c is on an extension line of the transport path (supply path) of the paper P, that is, the paper of the paper feed rollers 8 a and 8 b. It comes to be located on the straight line which connects P clamping part and the clamping part by the clamping rollers 31 and 32 (refer FIG. 4).
[0044]
The shutter 24 covers the sheet delivery outlet 27d when the sheet cassette 20 is not mounted in the cassette storage section 4, and the shutter 24 retracts from the sheet delivery outlet 27d when mounted on the cassette storage section 4. The paper P is configured to be sent to the laminating unit C.
[0045]
As shown in FIGS. 2, 3, 4, and 6, the laminating unit C is provided with a sandwiching roller unit 30 including a pair of upper and lower rollers 31 and 32. The nipping roller means 30 is supported at a position where the nipping position is opposed to the sheet delivery outlet 27 d of the sheet cassette 20 mounted in the cassette storage unit 4.
[0046]
The lower roller 32 rotatably supported by the left and right chassis 1a 'is a driving roller that is rotated by driving means such as a motor (not shown). On the other hand, the upper roller 31 is a driven roller attached so as to be able to idle, and rotates in contact with the driven lower roller 32. In the laminating apparatus 1 of the present invention, the upper driven roller 31 is in contact with the lower roller 32 in conjunction with the movement of the swing mechanism 3 of the paper feed rollers 8a and 8b, as shown in FIG. It is configured to be separated.
[0047]
Next, the configuration of the swing mechanism 3 will be described with reference to FIGS. 2 and 3.
[0048]
The pair of left and right main swing arms 34, 34 rotatably supported by lower pivot pins 33 attached to the lower portions of the left and right chassis 1 a ′, 1 a ′ are positioned at the upper and lower halfway positions. Paper rollers 8a and 8b are rotatably supported, and a paper sensor 35 for detecting the leading edge of the paper P to be conveyed is attached to a position of the connecting plate 34a that connects both the main swing arms 34 and 34. It has been. In addition, laterally in the middle of a pair of left and right cassette pressing support arms 37 and 37 pivotally attached to upper pivot pins 36 attached to the upper parts of the left and right chassis 1a 'and 1a'. The projecting guide pins 38, 38 are slidably fitted into upper and lower elongated holes 39 formed on the upper side of the pair of left and right main swing arms 34, 34, and a pair of left and right cassette pressing support arms 37, On the front end side of 37, a pressing roller 40 for pressing from above the sheet discharge side upper portion of the casing 23 of the sheet cassette 20 fitted in the cassette storage portion 4 is rotatably mounted.
[0049]
Furthermore, both ends of the upper roller 31 are rotatably supported by a pair of roller arms 41 and 41 rotatably supported by pins 44 on the distal end side of the pair of left and right cassette pressing support arms 37 and 37. One end of each torsion spring 44 supported by the cut and raised piece 43 in the middle of the pair of left and right cassette pressing support arms 37 and 37 is locked to the cassette pressing support arm 37, and the torsion spring 44 Are engaged so as to bias the roller arm 41 downward.
[0050]
Then, the A3 size casing 23a is set directly in the cassette storage section 4, or the attachment 60 in which the A4 size casing 23b or the A6 size casing 23c is set is set in the cassette storage section 4 in advance. Alternatively, after the attachment 60 is set in the cassette housing portion 4 and the housing 23b and the housing 23c are inserted, the operator holds the tip end side of the cassette pressing support arm 37 with his hand, Then, the casing 23 is pressed by the pressing roller 40 so that the casing 23 does not float up, and the postures of the pair of left and right cassette pressing support arms 37, 37 are engaged with the engaging portion (not shown) of the chassis 1a 'or the outer casing 1a. Engage to hold. At the same time, the upper roller 31 mounted on the roller arms 41 and 41 is pressed against the lower roller 32 by the urging force of the torsion spring 44 (see the solid line state in FIG. 3).
[0051]
Further, when the casing 23 is set in the pressed state, the pair of left and right main swing arms 34 and 34 are formed from the sliding connection relationship between the guide pins 38 of the cassette pressing support arms 37 and 37 and the upper and lower elongated holes 39. In FIG. 3, the pair of upper and lower paper feed rollers 8 a and 8 b serving as paper feed means mounted on the main swinging arms 34 and 34 are rotated to the right and the sheet on the stack introduction side of the sheet cassette 20. It moves so that it may approach the insertion port 27c. This state is detected by, for example, touching a sensor 46 such as a limit switch provided on the laminating apparatus 1 with the tip 45a of the detection arm 45 extending from the lower paper feed roller 8b to the upstream side of the sheet conveyance, and the sheet cassette 20 It is possible to notify the operator of the set state via the display unit.
[0052]
Conversely, when the pair of left and right cassette pressing support arms 37 and 37 are rotated in the upper left direction in FIG. 3 to release the casing pressing state, the upper roller 31 mounted on the roller arms 41 and 41 on the front end side thereof is While moving away from the lower roller 32, the main swinging arms 34, 34 are also rotated to the left, and the upper and lower pairs of paper feed rollers 8a, 8b as paper feed means are on the stacked article introduction side of the sheet cassette 20. It moves away from the paper insertion slot 27a (see the two-dot chain line state in FIG. 3).
[0053]
The function of the sandwiching roller means 30 described above is to sandwich the sheet P fed between the sheet S1 and the sheet S2 supplied from the sheet cassette 20 mounted in the sheet supply unit B together with the sheets S1 and S2. It sends out while joining the person. The sheet P sandwiched between the sheets S1 and S2 supplied from the sheet cassette 20 is sent out while being sandwiched by the sandwiching roller means 30, so that the sheet P is adhered by the sheets S1 and S2 and laminated. R is obtained.
[0054]
Although not described in detail in the cutting part D, a transverse cutting mechanism (not shown) for cutting the laminate R sent out from the laminate processing part C in the X direction (perpendicular to the feeding direction of the laminate R); A vertical cutter blade 66 (see FIG. 6) of a vertical cutting mechanism for cutting the laminated body R in the Y direction which is the feeding direction is provided as a cutter means.
[0055]
The disc-shaped cutter blade in the horizontal cutting mechanism is provided with a spiral groove in the center. Further, the chassis 1a ′ is provided with a spiral shaft (not shown) extending in the lateral direction, and the spiral shaft is fitted in the spiral groove of the cutter blade. The above-described spiral shaft is rotatably supported by the chassis 1a ', and is further connected to a motor (not shown). When the motor is driven to rotate, the spiral shaft rotates, the cutter blade fitted to the spiral shaft moves in the X direction, and cuts the laminate R in the lateral direction.
[0056]
The cutter blade 66 of the vertical cutting mechanism cuts out the side edge (ear) portion of the laminate R when the width of the sheets S1 and S2 is excessively large with respect to the paper P.
[0057]
The laminating operation with the above configuration will be described. In advance, the A3 size sheet cassette 20 is set directly in the cassette storage unit 4 or the small size A4 and A6 size sheet cassettes 20 are set in the attachment 60 and the cassette storage unit. Put in 4.
[0058]
Subsequently, when the sheet cassette 20 is mounted, the tips of the sheets S1 and S2 of the sheet cassette 20 are bonded to each other in advance. In this state, the cassette pressing support arm 37 is rotated upward, the pressing roller 40 holds the casing 23, and the holding rollers 31 and 32 hold the leading ends of the pair of sheets S 1 and S 2. I ’m going At the same time, the main oscillating arms 34 and 34 are rotated toward the front side of the housing 23, and the upper and lower paper feed rollers 8a and 8b, which are paper feed roller means, approach the front surface of the housing 23 and The distance between the rollers can be shortened.
