Description

  The present invention relates to a sheet feeding roller driving mechanism and a sheet feeding apparatus.

  There is known an apparatus for sending paper sheets one by one from a stacking unit of stacked paper sheets. For example, in Patent Document 1, a sheet feeding roller is brought into contact with the lowermost sheet of the sheet stacking unit from below, and the sheets are fed one by one from the lower side of the sheet stacking unit by rotation of the feeding roller. A sending device is described. In such a paper sheet feeding apparatus, a method of rotating a feeding roller through a belt or a plurality of gears using an electric motor as a driving force is generally employed.

  Patent Document 2 describes a mechanism for opening and closing a pair of blades by swinging a swinging rod, although it is not related to the delivery of paper sheets. It connects a crank fixed to the rotating shaft of the blade and a swing rod, opens and closes the blade by swinging the swing rod, and provides biasing means for rotating the blade beyond the dead center of the crank. It is a thing.

  In the paper sheet feeding device, use of a power source such as an electric motor is suitable for continuously feeding paper sheets, but is not suitable for optional or intermittent feeding of paper sheets, and a belt. Equipment and gears are required, which increases the cost of the apparatus and makes maintenance cumbersome.

  The present invention solves this problem by adopting a swing slider crank mechanism for rotational driving of the feed roller.

  However, in this mechanism, the feed roller cannot be rotated beyond the dead center of the crank only by swinging the swinging rod. On the other hand, Patent Document 2 discloses provision of an urging means that enables rotation beyond the dead center of the crank. However, simply providing the urging means rotates the delivery roller. I can't let you.

  Therefore, the present invention provides a feeding roller driving mechanism and a sheet feeding device that rotate a sheet feeding roller without using a power source such as an electric motor.

  In order to solve the above problems, the present invention combines a cam mechanism with a swing slider crank mechanism.

That is, the drive mechanism of the paper sheet feeding roller that feeds the paper sheet presented here is:
A crank member coupled to the rotating shaft of the feed roller and a swing rod that is swung up and down by a pedal are connected by a sliding pair, and the crank member is rotated by the swing of the swing rod to rotate the crank member. A swing slider crank mechanism for rotating the delivery roller;
A cam coupled to the rotation shaft of the feed roller, and a cam pushing member elastically pressed against the cam by an urging means, exceeding the upper and lower dead centers of the swing slider crank mechanism; And a cam mechanism for applying a rotational force to the delivery roller via the cam pushing member and the cam by the urging means so that the delivery roller rotates in the paper sheet delivery direction. To do.

  In this drive mechanism, when the feeding roller is rotated to the upper and lower dead points of the swinging slider crank mechanism by swinging the swinging rod, the feeding roller is moved from the cam pushing member to the cam by the biasing means. A rotation force is applied to the feed roller, and the delivery roller rotates beyond the dead point. That is, the delivery roller rotates once by the cooperation of the swing slider crank mechanism and the cam mechanism. Accordingly, the paper sheet can be fed out by rotating the feeding roller as required by merely swinging the swinging rod.

Further, the paper sheet sending device presented here is a device for sending the stacked paper sheets in order from the lower side,
A paper sheet delivery roller that contacts the bottom of the stacked paper sheets from below;
A crank member coupled to the rotating shaft of the feed roller and a swing rod that is swung up and down by a pedal are connected by a sliding pair, and the crank member is rotated by the swing of the swing rod to rotate the crank member. A swing slider crank mechanism for rotating the delivery roller;
A cam fixed to the rotating shaft of the feed roller, and a cam pressing member elastically pressed against the cam by an urging means. And a cam mechanism for applying a rotational force to the delivery roller so that the delivery roller rotates in the paper sheet delivery direction.

  This paper sheet feeding device uses the drive mechanism of the paper sheet feeding roller, and the feeding roller is rotated by the swinging of the swinging rod, and comes into contact with the feeding roller of the stacked paper sheets. The lowermost sheet is fed out by friction with the feeding roller. When the feed roller rotates to the upper and lower dead centers of the swing slider crank mechanism, a force is applied by the urging means to rotate the feed roller in the paper feed direction from the cam pushing member to the cam. Rotates beyond the dead center. That is, the delivery roller rotates once by the cooperation of the swing slider crank mechanism and the cam mechanism. Therefore, it is possible to feed the paper sheets in order from the lower side of the stacked paper sheets by arbitrarily rotating the feeding roller only by swinging the swinging rod.

  In a preferred embodiment, a stopper that prevents the upper paper sheet from advancing when the upper paper sheet is dragged to the lowermost paper sheet to be fed forward of the feeding roller in the paper sheet feeding direction. Is provided. The stopper has a stopper surface facing the stacked paper sheets and an inclined surface extending downward from the lower end of the stopper surface to the front, and the stopper surface and the inclined surface form an obtuse angle. Yes.

  On the other hand, the delivery roller is provided so that the front part of the stacked paper sheets is supported by the roller peripheral surface, and is formed so that the delivery of one paper sheet is completed in one rotation. Further, as the lowermost paper sheet approaches the stopper, the feeding roller has a higher sheet supporting surface on the roller peripheral surface, and the stacked paper sheets are inclined upward so that the lowermost sheet is in the lowermost position. Of the paper sheet hits the inclined surface of the stopper, while the upper paper sheet dragged by the lowermost paper sheet hits the stopper surface, and the lowermost paper sheet of the stopper The distance from the rotation center of the feed roller to the roller circumferential surface changes so that the paper sheet support surface becomes lower as it passes under.

  According to this aspect, when the upper paper sheet is dragged to the lowermost paper sheet with the rotation of the feeding roller, the upper paper sheet and the lowermost paper sheet are stopped by the stopper of the stopper. It progresses diagonally upward toward the obtuse angle part formed by the surface and the inclined surface. For this reason, when the upper paper sheet and the lowermost paper sheet hit the obtuse angle part, they are easily separated into upper and lower parts, which is advantageous for preventing the upper paper sheet from moving forward.

In a preferred embodiment, two release papers arranged in front and rear in the paper sheet feeding direction are provided on the lower surface of the paper sheet. The delivery roller is rotated once to finish delivering one sheet of paper,
A paper sheet receiver disposed at intervals before and after receiving the front part and the rear part of the paper sheet delivered by the delivery roller;
A paper sheet that descends between the front and rear paper sheet receivers and bends the paper sheets so that the front edge of the rear release paper is peeled off from the paper sheets received by the front and rear paper sheet receivers. A bending tool,
A release paper peeling tool for preventing the rear release paper from moving forward so that the rear release paper is peeled off the paper when the bent paper sheets are pulled forward together with the front release paper; ,
The swinging bowl and the paper sheet bending tool are moved so that the paper sheet bending tool is raised by the forward movement of the swinging hook and the paper sheet bending tool is lowered by the backward movement of the swinging hook. And a link mechanism for coupling.

  Therefore, the paper sheet can be sent out by the feed roller and the front end portion of the rear release paper can be peeled off by the paper sheet bending tool by swinging the swinging rod. When the bent paper sheets are pulled forward together with the front release paper, the release paper peeling tool prevents the rear release paper from moving forward, and as a result, the rear release paper is peeled off from the paper sheets.

  In a preferred embodiment, the release paper is wider than the paper sheet, and both sides of the release paper are projected to the outside of the paper sheet, and the paper sheet bending tool is received by the front and rear paper sheet receivers. A release paper peeling tool is provided which is composed of an elevating roller that comes into contact with the formed paper sheet from above and bends the paper sheet.

  The release paper peeling tools on both sides of the lift roller are provided so as to protrude downward from the lift roller and come into contact with both side portions of the release paper projecting on both outer sides of the paper sheets. Further, when the lifting roller reaches the lowering end, the distance between the lifting roller and the front paper sheet receptacle is wider than the thickness of the paper sheet.

  Accordingly, when the elevating roller and the release paper peeling tool are lowered, the elevating roller bends the paper sheet, and the front end portion of the rear release paper is peeled from the paper sheet. From this state, when the paper sheet is wound around the lifting roller together with the release paper on the front side and pulled up obliquely upward, the release paper on the rear side is prevented from moving forward by the release paper peeling tool protruding downward from the lifting roller. As a result, it is peeled off from the paper and falls. In the state where the paper sheet is wound around the lifting roller, the paper sheet does not come into contact with the front paper sheet receiver, so that the paper sheet from which the rear release paper has been peeled is prevented from adhering to the front paper sheet receiver. It is done.

According to the present invention, the swing slider crank mechanism that rotates the paper sheet feed roller by swinging of the swing rod, and the feed roller rotates beyond the upper and lower dead points of the swing slider crank mechanism. Since the cam mechanism for applying a rotational force to the delivery roller is provided, the delivery roller can be arbitrarily rotated to feed out the paper sheet by merely swinging the swinging rod with the pedal .

  Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. The following description of the preferred embodiments is merely exemplary in nature and is not intended to limit the invention, its application, or its use.

  In the paper sheet feeding apparatus shown in FIG. 1, 1 is a storage case for stacking and storing paper sheets, 2 is a swinging slider crank mechanism for rotating a feeding roller (friction roller) 3 for feeding paper sheets, A pedal 5 for driving the swing slider crank mechanism 2 is a link mechanism for driving a peeling device 6 for peeling the release paper from the paper sheet. The storage case 1 is supported by the machine base 7.

  As shown in FIG. 2, release papers 9a and 9b are provided on the back surface of the paper sheet 8 so as to be lined up before and after the paper sheet feeding direction. The release papers 9 a and 9 b are wider than the paper sheet 8, and both side portions of the release papers 9 a protrude from both sides of the paper sheet 8.

  As shown in FIG. 3, a paper sheet mounting table 11 is provided in the housing case, and the feeding roller 3 is disposed in front of the paper sheet mounting table 11 in the paper sheet feeding direction. The paper sheets 8 with release paper are stacked and placed so as to straddle the sending roller 3 and the paper sheet placing table 11 and at intervals in the longitudinal direction of the sending roller 3. Although illustration is omitted, a partition wall that divides the paper sheet loading section into two places is erected in the center of the paper sheet loading table 11.

  Since the feeding roller 3 contacts the lowermost paper sheet 8 of the stacked paper sheets 8 from below, when the feeding roller 3 is rotated, the stacked paper sheets 8 are sequentially sent out from the lower side. It will be. One sheet 8 with release paper is delivered by one rotation of the delivery roller 3.

  A crank member 13 constituting the swing slider crank mechanism 2 is coupled to one end of the rotating shaft 12 of the feed roller 3. A cam 15 constituting a cam mechanism 14 is coupled to the other end of the rotating shaft 12. The forward movement of the upper paper sheet 8 when the upper paper sheet 8 is dragged to the lowermost paper sheet 8 to be sent is prevented in front of the feeding roller 3 in the paper sheet feeding direction. A stopper 16 is provided.

  In front of the stopper 16, receiving rollers 17 and 18 are provided that are spaced apart from each other to receive the paper sheet 8 that has passed under the stopper 16. The receiving rollers 17 and 18 are provided in parallel with the feeding roller 3. In the present embodiment, two sets of receiving rollers 17 and 18 are provided corresponding to the above-described two paper sheet placement portions.

(Oscillating slider crank mechanism and cam mechanism)
The crank member 13 is provided with a pin 21 at a position away from the axis of the disk. The swing slider crank mechanism 2 is configured by providing the pin 21 of the crank member 13 in a long hole 23 formed in the swing rod 22 so as to be freely movable (slidably coupled with each other). As shown in FIG. 1, one end of the swing rod 22 is pivotally supported by the housing case 1, and the other end is connected to the pedal 4 by a link member 24. The swing rod 22 is biased by a biasing means (tensile spring) 25 in a direction in which the swing returns to one side (the direction in which the pedal 4 returns).

  The cam mechanism 14 applies a rotational force to the feed roller 3 so that the feed roller 3 rotates in the sheet feeding direction beyond the upper and lower dead centers of the swing slider crank mechanism 2. More specifically, as shown in FIG. 4, the cam mechanism 14 includes a cam 15, a cam pressing member 27, and an urging means (tensile spring) 28 that elastically presses the cam pressing member 27 against the cam 15. It is constituted by. The cam pushing member 27 has an L shape, and a central corner portion thereof is pivotally supported by the housing case 1, and is attached between the other end and the housing case 1 so that one end thereof is pressed against the cam 15. A biasing means 28 is provided.

  The cam 15 includes a cam surface 15a on the top dead center side to which the cam pushing member 27 comes into contact when the swing bar 22 moves up to reach the top dead center, and the bottom dead center when the swing bar 22 moves down. And a cam surface 15b on the bottom dead center side with which the cam pushing member 27 comes into contact.

  When the cam pushing member 27 comes into contact with the cam surface 15a on the top dead center side, the biasing means 28 applies a rotational force to the cam 15 via the cam pushing member 27, so that the feed roller 3 exceeds the top dead center and passes the paper. It rotates by a predetermined angle in the leaf delivery direction. Thereby, when the swinging rod 22 is moved downward, the feeding roller 3 is further rotated in the paper sheet feeding direction. Similarly, when the cam pushing member 27 contacts the cam surface 15b on the bottom dead center side, the biasing means 28 applies a rotational force to the cam 15 via the cam pushing member 27, so that the delivery roller 3 exceeds the bottom dead center. And rotate a predetermined angle in the paper sheet feeding direction. As a result, when the swinging rod 22 is moved upward, the feeding roller 3 is further rotated in the paper sheet feeding direction.

  Further, on the rear side of each of the cam surfaces 15a and 15b in the rotational direction of the cam 15, a cam pushing member is provided so as to prevent the reverse rotation of the cam 15 after the feed roller 3 has rotated a predetermined angle beyond the upper and lower dead points. The top dead center side engaging portion 15c and the bottom dead center side engaging portion 15d with which 27 is engaged are formed in a recessed shape.

  FIG. 4 shows the swing slider crank mechanism 2 and the cam mechanism 14 when the pedal 4 is not depressed. The swing rod 22 is pulled up by the urging means 25, and the cam pushing member 27 is engaged with the engaging portion 15c on the top dead center side of the cam 15 by the urging means 28. Therefore, when the pedal 4 is stepped on, the feeding roller 3 rotates in the sheet feeding direction by the swinging lever 22 moving downward (rotation by the swinging slider crank mechanism 2).

  When the swing rod 22 reaches the bottom dead center, the cam pushing member 27 comes into contact with the cam surface 15b on the bottom dead center side of the cam 15, as shown in FIG. Thereby, a rotational force is applied to the cam 15 by the biasing means 28 via the cam pushing member 27, and the feeding roller 3 rotates by a predetermined angle in the paper sheet feeding direction (rotation by the cam mechanism 14).

  As a result, as shown in FIG. 6, the cam pushing member 27 is engaged with the engaging portion 15 d on the bottom dead center side of the cam 15. Therefore, when the depression of the pedal 4 is released and the swinging bar 22 is moved upward by the biasing force of the biasing means 25, the feeding roller 3 rotates in the sheet feeding direction (rotation by the swinging slider crank mechanism 2).

  As a result, as shown in FIG. 7, the cam pushing member 27 comes into contact with the cam surface 15 a on the top dead center side of the cam 15. Thereby, a rotational force is applied to the cam 15 by the biasing means 28 via the cam pushing member 27, and the feeding roller 3 rotates by a predetermined angle in the paper sheet feeding direction (rotation by the cam mechanism 14).

  As a result, as shown in FIG. 4, the cam pushing member 27 is engaged with the engaging portion 15 c on the top dead center side of the cam 15.

  As described above, by combining the swing slider crank mechanism 2 and the cam mechanism 14, the feed roller 3 can be rotated once in the paper feed direction by merely swinging the swing rod 22. Class 8 can be sent out reliably.

(About stopper)
As shown in FIG. 8, the stopper 16 has a stopper surface 16a facing the stacked paper sheets, and an inclined surface 16b extending downward from the lower end of the stopper surface 16a to the front. The surface 16a and the inclined surface 16b form an obtuse angle.

  On the other hand, the feed roller 3 is an eccentric roller whose rotation shaft 12 is deviated from the geometric center of the perfect circle roller. The delivery roller 3 supports the front portion of the paper sheet 8 at a portion closest to the rotation shaft 12 on the circumferential surface of the roller in a standby state where the paper sheet 8 is not delivered. This portion is at the same height as the upper surface of the paper sheet mounting table 11. Therefore, the entire stacked paper sheets 8 are placed on the feed roller 3 and the paper sheet placing table 11 in a horizontal state. In FIG. 8, reference numeral 29 is a weight for pressing the stacked paper sheets 8.

  When the feeding roller 3 starts to rotate, the rotation shaft 12 is decentered, so that the support height of the paper sheet 8 by the roller peripheral surface gradually increases as the lowermost paper sheet approaches the stopper 16. As a result, the stacked paper sheets are in a state where the front side is elevated and inclined upward. As shown in FIG. 9, the lowermost paper sheet 8 hits the inclined surface 16b of the stopper 16, and the upper paper sheet 8 dragged by the lowermost paper sheet 8 hits the stopper surface 16a.

  As the feed roller 3 rotates, the lowermost paper sheet 8 passes under the stopper 16, but the upper paper sheet 8 is kept in a state in which advancement is prevented by the stopper surface 16a. As the lowermost paper sheet 8 is delivered, the support height of the paper sheet 8 by the roller peripheral surface becomes lower.

  As described above, when the upper paper sheet 8 is dragged to the lowermost paper sheet 8 as the feed roller 3 rotates, the upper paper sheet 8 and the lowermost paper sheet 8 Advances obliquely upward toward an obtuse angle portion formed by the stopper surface 16a and the inclined surface 16b of the stopper 16. For this reason, when the upper paper sheet 8 and the lowermost paper sheet 8 hit the obtuse angle portion, the upper paper sheet 8 is easily separated into upper and lower parts, which is advantageous for preventing the upper paper sheet 8 from moving forward.

(Release paper peeling device 6)
As shown in FIG. 1, the release paper peeling device 6 is provided at the lower ends of two elevating rods 31 extending in the vertical direction and spaced apart in the width direction of the delivery roller 3.

  As shown in FIG. 10, the release paper peeling device 6 includes a lifting roller 33 as a paper sheet bending tool supported by a bearing 32 at the lower end of the lifting rod 31, and a pair that moves up and down together with the lifting roller 33. The release paper peeling tool 34 is provided.

  The raising / lowering roller 33 is provided in parallel with the sending roller 3 and descends between the receiving rollers 17 and 18 so that the paper sheet 8 received by the receiving rollers 17 and 18 is curved so as to protrude downward. Let The release paper peeling tool 34 is provided on both outer sides of the lifting roller 33 in the axial direction, and protrudes below the lifting roller 33. The release paper peeling tool 34 is provided on both sides of the release papers 9a and 9b protruding from both outer sides of the paper sheet 8 (at the boundary between the front release paper 9a and the rear release paper 9b as shown in FIG. 11). It is provided to hit. As shown in FIGS. 12 and 13, the distance between the elevating roller 33 and the front receiving roller 17 when the elevating roller 33 reaches the lower end is wider than the thickness of the paper sheet 8.

  Therefore, as shown in FIGS. 11 and 12, when the lifting roller 33 and the release paper peeling tool 34 are lowered, the lifting roller 33 bends the paper 8 and the release paper peeling tool 34 is the front end of the rear release paper 9b. The part is peeled off from the paper sheet. In this state, as shown in FIG. 13, when the paper sheet 8 is pulled up forward and obliquely upward while being wound around the lifting roller 33 together with the front release paper 9 a, the rear release paper 9 b is lifted from the lifting roller 33. Also, as a result of the forward movement being prevented by the release paper peeling tool 34 protruding downward, it is peeled off from the paper sheet 8 and dropped. In a state where the paper sheet 8 is wound around the elevating roller 33, the paper sheet 8 does not contact the front receiving roller 17, and therefore the paper sheet 8 from which the rear release paper 9 b has been peeled is applied to the front receiving roller 17. Adhesion is avoided.

(Link mechanism for lifting and lowering the peeling device)
As shown in FIG. 1, an arm 41 extending forward and a swing link 42 extending in the front-rear direction are coaxially supported on both side surfaces of the upper portion of the housing case 1 to raise and lower the release paper peeling device 6. . A support shaft 43 is passed between the front end of the arm 41 and the front end of the swing link 42, and the upper end portion of the elevating rod 31 is supported on the support shaft 43. A guide 44 for guiding the vertical movement of the lifting rod 31 is fixed to the housing case 1.

  The middle part of the swing link 42 is pivotally supported by the upper part of the side surface of the housing case 1 and swings up and down. The peeling device 6 moves up and down together with the lifting rod 31 by swinging of the swing link 42. In order to swing the swing link 42 by the swing rod 22, the rear end of the swing link 42 and the swing rod 22 are connected by a connecting link 45 extending in the vertical direction. The swing mechanism 42 and the connecting link 45 constitute the link mechanism 5.

  Thus, a delay that delays the lowering of the peeling device 6 with respect to the delivery of the paper sheet 8 so that the peeling device 6 reaches the lower end after the release paper with release paper 8 is sent to the receiving rollers 17 and 18. The mechanism is incorporated in the link mechanism 5. The delay mechanism includes a holding unit that holds the peeling device 6 in the raised standby position, and a release unit that releases the holding delay. This will be specifically described below.

  As shown in FIG. 14, the holding means includes an engaging plate 48 that is provided integrally with the swing link 42, and a rotating plate 49 that is rotatably supported on the side surface of the housing case 1 by a horizontal support shaft. It becomes. By engaging the stopper portion 49a of the rotating plate 49 with the engaging portion 48a of the engaging plate 48, the swing link 42 is prevented from swinging in the direction in which the peeling device 6 is lowered. That is, the peeling device 6 is held at the standby position by the stopper portion 49a. The rotating plate 49 is urged by an urging means (tensile spring) 51 so as to rotate in a direction in which the stopper portion 49 a engages with the engaging plate 48.

  Further, the connecting link 45 abuts against the contact portion 49b of the rotation plate 49 when the link link 45 is moved upward by a predetermined distance from the lower end thereof, and the rotation plate 49 is rotated against the urging force of the urging means 51. A protrusion 45a is provided. The protrusion 45a of the connecting link 45 and the contact portion 49b of the rotating plate 49 constitute means for delaying the holding of the peeling device 6 by the stopper portion 49a.

  Further, the swing link 42 and the connection link 45 are connected by a sliding pair formed by movably providing a pin member 46 fixed to the swing link 42 in a long hole 47 formed in the upper end portion of the connection link 45. Yes. Thus, no force is transmitted from the connecting link 45 to the swing link 42 until the connecting link 45 moves up the predetermined distance from the descending end.

  Here, as shown by a solid line in FIG. 14, when the swing rod 22 is on the top dead center side, the peeling device 6 is located at the lower end. The rotating plate 49 has a contact portion 49 b received by the protrusion 45 a of the connecting link 45, and the stopper portion 49 a is rotated to a position disengaged from the engaging plate 48.

  When the pedal 4 is stepped on and the swing rod 22 is moved downward, the feeding roller 3 rotates in the sheet feeding direction as described above, and the feeding of the sheet 8 is started. At this time, since the connecting link 45 moves downward as the swinging rod 22 moves downward, the swinging link 42 rotates and the peeling device 6 rises to the standby position. Then, with the downward movement of the connecting link 45, the engagement between the protrusion 45a and the contact portion 49b of the rotating plate 49 is released. As a result, the rotation plate 49 is rotated by the urging force of the urging means 51, the stopper portion 49a is engaged with the engagement portion 48a of the engagement plate 48, and the peeling device 6 is held at the standby position.

  When the depression of the pedal 4 is released, the swing rod 22 moves upward, so that the feeding roller 3 further rotates in the sheet feeding direction as described above, and the feeding of the sheet 8 proceeds. The connecting link 45 also moves upward with the upward movement of the swinging rod 22, but the swinging link 42 and the connecting link 45 are connected by the pin member 46 and the long hole 47, so the swinging link 42 does not move. .

  When the connecting link 45 moves upward by a predetermined distance, the protrusion 45 a hits the contact portion 49 b of the rotating plate 49. Then, the rotating plate 49 rotates against the urging force of the urging means 51 by further upward movement of the connecting link 45. As a result, the engagement between the stopper portion 49a of the rotating plate 49 and the engaging portion 48a of the engaging plate 48 is released. Thereby, the swing of the swing link 42 becomes free.

  As a result, when the pin member 46 of the swing link 42 moves upward through the long hole 47 of the connecting link 45, the peeling device 6 is lowered by its own weight together with the lifting rod 31 and is already received by the receiving rollers 17 and 18. The peeling device 6 comes into contact with the sheet 8 with release paper. Therefore, the paper sheet 8 can be reliably bent by the peeling device, and the rear release paper 9b can be peeled off.

  Although the above embodiment is a case where the release paper 8 with release paper and the release paper are peeled off, the present invention can be used for delivery of paper regardless of the presence or absence of release paper. In the case where the paper sheets are only sent out one by one, the peeling device 6 and its driving mechanism are not necessary.
