  The drum 42 can rotate in both the clockwise direction and the counterclockwise direction in FIGS. 2 to 4 about the shaft 42a. Specifically, when the paper sheets sent from the transport unit 20 to the temporary storage unit 40 are stored in the drum 42, the drum 42 rotates in the counterclockwise direction in FIGS. Paper sheets sent to the vicinity of 42 are wound around the drum 42 together with the tapes 90, 92 and 94. On the other hand, when the paper sheets stored in the drum 42 are fed out to the transport unit 20, the drum 42 rotates in the clockwise direction in FIGS. 2 to 4, and the tapes 90, 92, and 94 are rotated from the drum 42. By rewinding, the paper sheets are released from each of the tapes 90, 92, 94 and sent to the transport unit 20. In the present embodiment, the paper sheets are transported along the short direction of the paper sheets in the temporary storage unit 40 and wound around the drum 42.

  Also, as shown in FIGS. 2 to 4, the temporary storage unit 40 is provided with a drive motor 64 that rotates the drum 42. More specifically, as shown in FIG. 8, a pulley 64a is connected to the drive motor 64 via a rotating shaft, and a drive belt 69 is stretched over the pulley 64a. The pulley 42b is also connected to the shaft 42a of the drum 42, and the drive belt 69 is stretched over the pulley 42b. Thus, when the drive motor 64 drives the pulley 64a to rotate, the rotational driving force by the drive motor 64 is transmitted to the shaft 42a via the drive belt 69, so that the drum 42 is driven to rotate.

  As shown in FIGS. 2 to 4, the temporary storage unit 40 is provided with guide rollers 52 and 54 for guiding the tapes 90, 92, and 94, and the guide rollers 52 and 54 serve as drums. Each tape 90, 92, 94 is guided between the tape 42 and the tape reel 58. In addition to the guide rollers 52 and 54, the temporary storage unit 40 is provided with guide rollers 50 and 56 for guiding the tapes 90 and 94 on both sides of the three tapes 90, 92 and 94, respectively.

Further, as shown in FIGS. 2 to 4, 8, and 9, a substantially triangular support plate 57 that supports the shafts of the guide roller 50 and the guide roller 56 is provided.

  More specifically, as shown in FIG. 9A, the central tape 92 among the three tapes 90, 92, 94 is conveyed between the drum 42 and the tape reel 58 by the guide rollers 52, 54. When the drum 42 rotates counterclockwise in FIGS. 2 to 4, the tape 92 unwound from the tape reel 58 is wound around the drum 42 through the guide roller 54 and the guide roller 52 in this order. It becomes like this. Further, when the tape reel 58 rotates in the clockwise direction in FIGS. 2 to 4, the tape 92 unwound from the drum 42 is wound around the tape reel 58 through the guide roller 52 and the guide roller 54 in order. Also, as shown in FIG. 9B, the two tapes 90, 94 of the three tapes 90, 92, 94 are conveyed between the drum 42 and the tape reel 58 by the guide rollers 52, 54, respectively. At the same time, it is conveyed around the drum 42 by the guide rollers 50 and 56. Here, when the drum 42 is rotated in the counterclockwise direction in FIGS. 2 to 4, the tapes 90 and 94 unwound from the tape reel 58 pass through the guide roller 54 and the guide roller 52 in order, and are about half a circumference of the drum 42. The tapes 90 and 94 are wound around the drum 42 through the guide roller 56 and the guide roller 50 in this order. Thus, when the paper sheet sent from the transport unit 20 to the temporary storage unit 40 passes between the guide rollers 50 and 52, the paper sheet is interposed between the pair of tapes 90 and between the pair of tapes 94. The sheets are sandwiched between the tapes 90 and 94, and the paper sheets are wound around the drum 42 together with the tapes 90 and 94. Further, when the tape reel 58 rotates in the clockwise direction in FIGS. 2 to 4, the tapes 90 and 94 unwound from the drum 42 pass through the guide roller 50 and the guide roller 56 in order, and correspond to about a half circumference of the drum 42. After being wound around the drum 42, the tapes 90 and 94 are wound around the tape reel 58 through the guide roller 54 and the guide roller 52 in order.

  As shown in FIGS. 2 to 4, a detection plate 60 that rotates in synchronization with the tape reel 58 is attached to the tape reel 58. As shown in FIG. 8, a plurality (specifically, for example, three) of detection plates 60 are provided corresponding to the respective tapes 90, 92, and 94. A photo interrupter 62 is provided in the vicinity of the detection plate 60 as a detection plate rotation amount detector for detecting the rotation amount of the detection plate 60. More specifically, the detection plate 60 is provided with a plurality of through holes 60a, and the photo interrupter 62 has a light emitting element and a light receiving element arranged with the outer peripheral edge of the detection plate 60 interposed therebetween. When the detection plate 60 rotates, the optical axis between the light emitting element and the light receiving element in the photo interrupter 62 is intermittently transmitted by the through holes 60a provided in the detection plate 60. Yes. As described above, when the detection plate 60 rotates, the photo interrupter 62 repeats the light transmission state and the light shielding state. The amount of rotation of the plate 60 is detected.

  Further, as shown in FIG. 8, torque limiters 58 b are provided on the side surfaces of the respective detection plates 60 corresponding to the respective detection plates 60. In FIG. 8, only one torque limiter 58b is shown, but actually three torque limiters 58b are provided to correspond to each of the three detection plates 60. Further, the inner portion of the torque limiter 58b is fixed to the shaft 58a by a pin or the like (not shown), and the inner portion of the torque limiter 58b rotates integrally with the shaft 58a. On the other hand, the outer portion of the torque limiter 58b is fixed to the side surface of the detection plate 60, and the outer portion of the torque limiter 58b rotates integrally with the detection plate 60 and the tape reel 58. Further, the detection plate 60 and the tape reel 58 are rotatable with respect to the shaft 58a. In the torque limiter 58b, when the external force (rotational driving force) applied to the inner and outer portions of the torque limiter 58b is smaller than the rotational resistance between these inner and outer portions, the inner portion of the torque limiter 58b. When the external force is larger than the rotational resistance between the inner part and the outer part of the torque limiter 58b, the inner part and the outer part are rotated with a constant load with respect to each other. Rotate while slipping. The shaft 58a is connected to a pulley 58c around which the drive belt 69 is stretched, and the pulley 58c incorporates a one-way clutch (not shown).

  When the drive motor 64 rotationally drives the pulley 64a to circulate and move the drive belt 69 in the direction in which the drum 42 winds the tapes 90, 92, 94, the drive belt 69 is driven by a one-way clutch built in the pulley 58c. Is not transmitted to the shaft 58a, and the shaft 58a does not rotate. In this case, the drum 42 rotates in the counterclockwise direction in FIGS. 2 to 4, so that the tapes 90, 92, 94 are wound around the drum 42. The tape reel 58 is also rotated in the counterclockwise direction in FIGS. 2 to 4 by the take-off operation. At this time, an external force (rotational driving force) applied to the outer portion of the torque limiter 58b is applied to the torque limiter 58b. By becoming larger than the rotational resistance between the inner part and the outer part, the outer part of the torque limiter 58b rotates while slipping with respect to the inner part with a rotational resistance of a constant load. On the other hand, when the drive motor 64 rotationally drives the pulley 64a to circulate and move the drive belt 69 in the direction in which the tape reel 58 winds the tapes 90, 92, 94, the driving force by the drive belt 69 is applied to the shaft 58a. And the rotational driving force is transmitted to the tape reel 58 via the torque limiter 58b, whereby the tape reel 58 is rotationally driven. In this case, each tape 90, 92, 94 is unwound from the drum 42 by rotating the tape reel 58 in the clockwise direction in FIGS. The drum 42 also rotates in the clockwise direction in FIGS. 2 to 4 by the unwinding operation, but the winding speed of the tapes 90, 92, 94 by the tape reel 58 depends on the tape 90, 92 from the drum 42. The tension of the tapes 90, 92, 94 is maintained by setting the gear ratios of the pulleys 42b, 58c so as to be always higher than the unwinding speed of 94, 94. At this time, the external force (rotational driving force) applied to the inner portion of the torque limiter 58b becomes larger than the rotational resistance between the inner portion and the outer portion of the torque limiter 58b, so that the inner portion of the torque limiter 58b becomes The outer part rotates while slipping with a rotational resistance of a constant load.

  As shown in FIGS. 2 to 4, the temporary storage unit 40 guides the paper sheets sent from the transport unit 20 to the temporary storage unit 40 to the drum 42 or the paper sheets fed out from the drum 42. Guide rollers 65, 66, 67, and 68 for guiding the product to the transport unit 20 are provided. More specifically, the pair of guide rollers 65 and 66 are arranged to face each other so that their outer peripheral surfaces come into contact with each other, and the pair of guide rollers 67 and 68 face each other so that their outer circumferential surfaces come into contact with each other. Are arranged. The paper sheets sent from the transport unit 20 to the temporary storage unit 40 first pass between the pair of guide rollers 65 and 66, and then pass between the pair of guide rollers 67 and 68, and then each tape. The drum is wound on the drum 42 by 90, 92 and 94. 2 to 4, when the drum 42 rotates in the clockwise direction, the tapes 90, 92, 94 are rewound from the drum 42, whereby paper sheets are discharged from the tapes 90, 92, 94. The discharged paper sheets first pass between the pair of guide rollers 67 and 68, then pass between the pair of guide rollers 65 and 66, and then sent to the transport unit 20.

  Further, as shown in FIGS. 2 to 4, a movable guide 82 is provided at the peripheral portion of the drum 42 so as to surround each tape 90, 92, 94 wound around the drum 42 in the temporary storage unit 40. . The movable guide 82 rotates about a shaft 83 provided coaxially with the shaft of the guide roller 52. Further, biasing means such as a spring 89 (see FIG. 7) for biasing the movable guide 82 about the shaft 83 in the counterclockwise direction in FIGS. 2 to 4 is provided. The movable guide 82 is provided with a bearing 84 that presses the paper sheet wound around the drum 42 toward the shaft 42 a side of the drum 42. The movable guide 82 is urged in the counterclockwise direction in FIGS. 2 to 4 by the urging means such as the spring 89, so that the bearing 84 is pressed upward in FIGS. 2 to 4. Thus, the paper sheets wound around the drum 42 are pressed toward the shaft 42a side of the drum 42 by the bearing 84. Further, since the movable guide 82 is urged in the counterclockwise direction in FIGS. 2 to 4 by the urging means such as the spring 89, the paper wound around the drum 42. Even if the outer diameter of each tape 90, 92, 94 is reduced by rewinding the leaves from the drum 42, the bearing 84 always contacts the paper sheets and presses the paper sheets.

  In the present embodiment, even when the paper sheet is folded when the drum 42 rotates in the clockwise direction in FIGS. 2 to 4 and the paper sheet is fed out from the drum 42, the folded paper sheet is folded. Guide portions 80 and 85 are provided to prevent the tape from sandwiching the tapes 90, 92, and 94 from both sides. Here, as described above, in the present embodiment, a plurality of tapes 90, 92, 94 are provided so as to be aligned along the axial direction of the drum 42, and the guide portions 80, 85 are respectively connected to the tapes 90, 92, 94. It is provided corresponding to. In FIGS. 2 to 4, such guide portions 80 and 85 are indicated by hatching.

  The guide unit 80 prevents the folded paper sheets from pinching the central tape 92 from both sides even when the paper sheets are folded when the paper sheets are fed from the drum 42. ing. Such a guide portion 80 is installed above the drum 42 and is rotatable about a shaft 81 extending in parallel with the shaft 42 a of the drum 42. The leading end portion of the guide portion 80 comes into contact with the tape 92 wound around the drum 42 by its own weight. In addition, instead of the guide part 80 contacting the tape 92 wound around the drum 42 by its own weight, the tip part of the guide part 80 is applied toward the drum 42 side by a biasing means such as a spring (not shown). You may be encouraged. Further, as shown in FIGS. 5 and 6, the guide unit 80 has a position in the axial direction of the drum 42 (that is, a position in the left-right direction in FIG. 6) facing the tape 92.

  In addition, the guide unit 80 is configured such that when the paper sheets are fed out from the drum 42 by rewinding the tapes 90, 92, 94 from the drum 42, the folded portion of the paper sheets is in the axial direction of the drum 42. The shape moves in a direction away from the tape 92. Specifically, as shown in FIG. 6, the guide unit 80 is configured so that when the temporary storage unit 40 is viewed from above, the sheet is fed out from the drum 42 (that is, in the downward direction in FIG. 6). ) The drum 42 has a triangular shape in which the width in the axial direction (that is, the width in the left-right direction in FIG. 6) gradually increases. That is, the guide portion 80 has a shape that gradually spreads outward in the width direction of the tape 92 as it advances in the direction in which the paper sheets are fed out from the drum 42. Since the guide portion 80 having such a configuration is provided so as to face the surface of the tape 92 so as to face the tape 92, the tapes 90, 92, 94 are rewound from the drum 42, whereby the paper is removed from the drum 42. Even if the folded portion of the paper sheet tries to get on the surface of the tape 92 when the leaf is fed out, the folded portion of the folded paper sheet comes into contact with the side surface of the guide portion 80. On the surface of the tape 92, and this prevents the folded paper sheets from pinching the tape 92 from both sides.

  In other words, if such a guide unit 80 is not provided in the temporary storage unit 40, the tapes 90, 92, and 94 are rewound from the drum 42, and the sheets are fed out from the drum 42. As shown in FIG. 18 (a), there is a cut portion at the front edge of the paper sheet in the feeding direction of the paper sheet (indicated by an arrow in FIG. 18 (a)). When a part of the paper is folded, the folded part (indicated by reference numeral S ′ in FIG. 18A) comes into contact with the opposite surface of the tape 92, thereby folding the folded paper. The leaves may pinch the tape 92 from both sides. In addition, when a part of the paper sheet is folded due to the cut portion formed at the front edge of the paper sheet, the folded part does not come into contact with the opposite surface of the tape 92. In some cases, the paper sheets that are sandwiched sandwich the tape 92 from both sides. As described above, when the folded paper sheets sandwich the tape 92 from both sides, the paper sheets are discharged from the tapes 90, 92, 94 in the vicinity of the guide rollers 50, 52. The portion of the paper sheet that is folded on the opposite surface of the tape 92 is sandwiched between the tape 92 and the guide roller 52, so that the paper sheet is torn from the cut portion or has a large orientation. There is a risk of change.

  As shown in FIG. 5 and the like, the movable guide 82 is provided with a pair of guide portions 85 facing the tapes 90 and 92. Further, in the movable guide 82, the paper sheets are disposed on both sides of each guide portion 85 when the paper sheets are stored in the drum 42 by winding the tapes 90, 92, 94 around the drum 42. An additional guide part 86 is provided for performing the following guidance. FIGS. 10 and 11 are perspective views of the movable guide 82 provided with the respective guide portions 85 and the additional guide portion 86 as described above. Each guide portion 85 prevents the folded paper sheets from pinching the tapes 90 and 94 from both sides even when the paper sheets are folded when the paper sheets are fed from the drum 42. It is like that. Here, as shown in FIGS. 5 and 6, each guide portion 85 has a position in the axial direction of the drum 42 (that is, a position in the left-right direction in FIG. 6) that faces the tapes 90 and 94. Yes.

  Further, as shown in FIGS. 5 and 6, each guide portion 85 has a width in the axial direction of the drum 42 (that is, in the downward direction in FIG. 6) in the direction in which the sheets are fed out from the drum 42 (that is, in the downward direction in FIG. 6). Both end edges extend along the circumferential direction of the drum 42 so that the size of the width in the left-right direction in FIG. 6 is constant. As shown in FIGS. 10 and 11, each guide portion 85 is disposed so as to protrude toward the drum 42 from the guide surface 86 a that guides the paper sheets in the additional guide portion 86. The guide surface 85a of the section 85 faces the tapes 90 and 94 with a slight gap from the surface of the tapes 90 and 94 wound around the drum 42. In particular, the movable guide 82 to which the guide portion 85 is attached is swingable about the shaft 83 in accordance with the amount of paper stored in the drum 42, and a bearing provided on the movable guide 82. The movable guide 82 is pressed about the shaft 83 in the counterclockwise direction in FIGS. 2 to 4 by an urging means such as a spring 89 so that 84 contacts the paper sheet wound around the drum 42. Regardless of whether the amount of paper sheets stored in the drum 42 is large or small, a slight gap is formed between the guide surface 85a of each guide portion 85 and the surface of each tape 90, 94 wound around the drum 42. Will come to be. Each guide portion 85 having such a configuration is provided so as to face the tapes 90 and 94 so as to form a slight gap between the tapes 90 and 94, so that the tapes 90 and 92 are respectively formed from the drum 42. , 94 when the paper sheet is unwound from the drum 42 when the paper sheet is unwound, even if the folded part of the paper sheet tries to get on the surface of each tape 90, 94, the folded part of the paper sheet is By contacting the side surface 85b and the side edge portion 85c (see FIGS. 10 and 11) of the guide portion 85, the folded portion is prevented from riding on the surfaces of the tapes 90 and 94. The paper sheets are prevented from sandwiching the tapes 90 and 94 from both sides.

  In other words, if each of the guide portions 85 is not provided in the temporary storage portion 40, the tapes 90, 92, and 94 are rewound from the drum 42 so that the paper sheets are removed from the drum 42. When the paper is fed, as shown in FIG. 18B, there is a cut portion at the front edge of the paper sheet in the feeding direction of the paper sheet (indicated by an arrow in FIG. 18B). When a part of the leaf is broken, the folded portion (indicated by reference symbol S ′ in FIG. 18B) is the tape 90, 94 (in the example shown in FIG. 18B, the tape). 94), the folded paper sheets may pinch the tape 90 from both sides. In such a case, when the paper sheets are discharged from the tapes 90, 92, 94 in the vicinity of the guide rollers 50, 52, the portion of the paper sheets that is folded on the opposite surface of the tape 94. Is sandwiched between the tape 94 and the guide roller 50 or the guide roller 52, there is a possibility that the paper sheet is torn from the cut portion or the direction is greatly changed.

  Moreover, in the temporary storage part 40 of this Embodiment, the scraper member 96 is provided in the vicinity of the guide roller 50 as shown in FIG. 2 thru | or FIG. More specifically, two scraper members 96 are provided corresponding to the tapes 90 and 94, and the tapes 90 and 94 between the drum 42 and the guide roller 50 are respectively attached to the scraper members 96. It comes to contact. The structure of such a scraper member 96 is demonstrated using FIG. 12 and FIG. FIG. 12 is a perspective view showing the configuration of the scraper member 96, and FIG. 13 is a front view showing the configuration when the scraper member 96 shown in FIG. 12 is viewed from the front.

  As shown in FIGS. 12 and 13, the tapes 90 and 94 between the drum 42 and the guide roller 50 come into contact with the tip portions 96 b and 96 c of the scraper member 96. Here, the tip portion of the scraper member 96 is not a simple linear shape, but is composed of a plurality of tip portions 96b, 96c that are different in direction from each other. When these tip portions 96b, 96c are combined, a so-called concave shape is formed. Since the tip portions are formed, the cross-sectional shapes of the tapes 90 and 94 are linear when the tapes 90 and 94 between the drum 42 and the guide roller 50 come into contact with the tip portions 96b and 96c of the scraper member 96. To bend into a curved shape (see FIG. 13). In FIG. 13, in order to make the shapes of the tapes 90 and 94 easier to see, the tapes 90 and 94 are separated from the tip portions 96b and 96c. The tip portions 96b and 96c are in contact with each other. Thus, the tip portions 96c on both sides of the tip portions 96b, 96c of the scraper member 96 are shaped to cover both side edges of the tapes 90, 94 that are in contact with the scraper member 96.

  The scraper member 96 is rotatable around a shaft 96a provided coaxially with the shaft of the guide roller 50. The shaft 96a of the scraper member 96 is provided with an urging means such as a torsion spring, and the urging means causes the scraper member 96 to rotate in the clockwise direction in FIGS. A rotating force is energized. As a result, as shown in FIGS. 2 to 4, the tip portions 96b and 96c of the scraper member 96 can be used with the drum 42 and the guide roller 50 regardless of whether the amount of paper sheets stored in the drum 42 is large or small. Are always in contact with the tapes 90 and 94 between them.

  Further, as shown in FIG. 13, when the tapes 90 and 94 between the drum 42 and the guide roller 50 come into contact with the tip portions 96b and 96c of the scraper member 96, the cross-sectional shapes of the tapes 90 and 94 are linear. The shape is deformed to a curved shape. For this reason, when the tapes 90, 92, 94 are rewound from the drum 42, the paper sheets discharged from the tapes 90, 92, 94, and the outermost tape that is one inner side than the paper sheets. There is a cut portion at the front edge of the paper sheet in the feeding direction of the paper sheet passing in the vicinity of the scraper member 96 in the state of being wound around 90, 92, 94, and this cut portion causes one of the above-mentioned paper sheets. Even when the section is detached from the tapes 90, 92, 94 wound on the drum 42 (the removed part of the paper is indicated by the reference symbol P of a two-dot chain line in FIG. 3), the paper It is possible to prevent an unrelated part from entering between the guide roller 50 and the tapes 90 and 94. More specifically, it is possible to prevent a part of the paper sheets that have come off from the tapes 90, 92, 94 wound around the drum 42 from entering between the scraper member 96 and the tapes 90, 94. At the same time, even if a part where the paper sheet is removed enters between the scraper member 96 and each of the tapes 90 and 94, a part of the paper sheet is interposed between the guide roller 50 and each of the tapes 90 and 94. It can suppress sending in.

  As a comparative example, FIG. 19 shows a configuration of a conventional scraper member. FIG. 19 is a front view showing a configuration of a scraper member 97 of the prior art. The scraper member 97 of the prior art is rotatable about a shaft 97a provided coaxially with the shaft of the guide roller 50. Further, the shaft 97a of the scraper member 97 is provided with an urging means such as a torsion spring, and the urging means causes the scraper member 97 to rotate around the shaft 97a toward the respective tapes 90 and 94. Power is to be energized. Further, as shown in FIG. 19, the tapes 90, 94 between the drum 42 and the guide roller 50 are brought into contact with the tip end portion 97 b of the scraper member 97. Here, since the front end portion 97b of the scraper member 97 of the prior art has a simple linear shape, each tape 90, 94 between the drum 42 and the guide roller 50 comes into contact with the front end portion 97b of the scraper member 97. Sometimes the cross-sectional shape of each tape 90, 94 remains linear. In such a case, when the tapes 90, 92, 94 are rewound from the drum 42, the paper sheets discharged from the tapes 90, 92, 94, and one sheet inside the paper sheets are present. There is a cut portion at the front edge of the paper sheet in the feeding direction of the paper sheet passing through the vicinity of the scraper member 96 in a state of being wound around the outermost tape 90, 92, 94, and the cut portion causes the above paper When a part of the leaves is detached from the tapes 90, 92, 94 wound around the drum 42, the removed part of the paper sheets is the leading end portion 97 b of the scraper member 97 and each tape 90, 94. At this time, a part of the paper sheet that has passed between the tip end portion 97 b of the scraper member 97 and each of the tapes 90 and 94 enters between the guide roller 50 and each of the tapes 90 and 94, and is wound from the drum 42. There is a possibility that the paper sheet to be taken out is torn from the portion that enters between the guide roller 50 and the tapes 90 and 94.

  Note that the scraper member 96 according to the present embodiment is not limited to the configuration shown in FIGS. 12 and 13. In the scraper member 96 shown in FIGS. 12 and 13, the tip portions 96 c on both sides are shaped so as to cover both side edges of the respective tapes 90, 94 contacting the scraper member 96. As shown in FIGS. 12 and 13, only one tip portion is the same as the tip portion 96c in FIGS. 12 and 13, and only one side edge of each of the tapes 90 and 94 contacting the scraper member is used. You may come to be covered with the front-end | tip part of a scraper member. In this case, when the tapes 90 and 94 between the drum 42 and the guide roller 50 come into contact with the scraper member, the cross sections of the tapes 90 and 94 are inclined from the horizontal state. It is possible to prevent a part of the paper sheets that have been detached from the tapes 90, 92, 94 wound around the sheet from entering between the scraper member 96 and the tapes 90, 94.

  Moreover, the scraper member of another structure by this Embodiment is shown in FIG.14 and FIG.15. The scraper member 98 shown in FIGS. 14 and 15 is rotatable about a shaft 98 a provided coaxially with the shaft of the guide roller 50. The shaft 98a of the scraper member 98 is provided with a biasing means such as a torsion spring. The biasing means causes the scraper member 98 to rotate around the shaft 98a toward the tapes 90 and 94. Power is to be energized. Further, the scraper member 98 is configured such that the tapes 90 and 94 between the drum 42 and the guide roller 50 come into contact with the front end portions 98b and 98c. Here, the tip portion of the scraper member 98 is not a simple linear shape, but is composed of a plurality of tip portions 98b, 98c having different directions, and the brush members 99 extending downward are provided on the tip portions 98c on both sides. Is attached. As shown in FIG. 15, when the tapes 90 and 94 between the drum 42 and the guide roller 50 come into contact with the tip portions 98b and 98c of the scraper member 98, the tapes 90 and 94 are brushes on both sides. It will be located between the members 99. By providing such a brush member 99, when the paper sheets are fed out from the drum 42 by rewinding the tapes 90, 92, 94 from the drum 42, in the paper feeding direction. Even when there is a cut portion at the front edge of the paper sheet, even if a part of the paper sheet is detached from the tapes 90, 92, 94 wound around the drum 42 due to the cut portion, the paper sheet It is possible to prevent a part of the removed portion from entering between the scraper member 98 and each of the tapes 90 and 94.

  Next, the configuration of the control system of the paper sheet processor 10 having the configuration as shown in FIG. 1 will be described with reference to FIG. The paper sheet processing machine 10 according to the present embodiment is provided with a control unit 35. The control unit 35 includes a first feeding mechanism 16 and a second feeding mechanism 18 provided in the deposit / withdrawal unit 14, and conveyance. Section 20, identification section 22, width direction alignment section 24, temporary storage section 40, feeding mechanism 31 provided in each paper sheet storage and feeding section 30, and feeding mechanism 33 provided in each paper sheet storage and feeding section 32, respectively. It is connected so that it can communicate. Here, the identification result of the paper sheets by the identification unit 22 is sent to the control unit 35. Further, the control unit 35 sends command signals to the first feeding mechanism 16, the second feeding mechanism 18, the transport unit 20, the width direction alignment unit 24, the temporary holding unit 40, each feeding mechanism 31, each feeding mechanism 33, and the like. As a result, these components are controlled.

  As shown in FIG. 16, an operation display unit 36, a storage unit 37, and a communication interface unit 38 are connected to the control unit 35 so as to be able to communicate with each other. The operation display unit 36 includes, for example, a touch panel disposed on the front surface or the upper surface of the housing 12, and the operator can input various commands to the control unit 35 through the operation display unit 36 and display the operation display. The section 36 displays the processing contents of the paper sheets in the paper sheet processing machine 10 and the amount of paper sheets (specifically, banknotes and checks) stored in the body of the paper sheet processing machine 10. It has come to be. The storage unit 37 also stores a history of processing contents of the paper sheets in the paper sheet processing machine 10 and paper sheets (specifically, banknotes and checks) stored in the body of the paper sheet processing machine 10. It is designed to store information such as the amount of money. The control unit 35 of the paper sheet processing machine 10 is connected to an external device such as a host terminal via a communication interface unit 38 so as to be able to communicate with the external device. Is to be done.

  Next, details of the configuration of the transport unit 20 provided in the paper sheet processor 10 will be described below with reference to FIG. As shown in FIG. 32, the transport unit 20 has a circulation belt 20a and a plurality of pinch rollers 20d provided to face the circulation belt 20a, and the circulation belt 20a circulates and moves. A sheet is conveyed one by one between 20a and each pinch roller 20d. Specifically, the circulation belt 20a is stretched by a plurality of pulleys 20b (two pulleys 20b in the example shown in FIG. 32), and one pulley 20b among the plurality of pulleys 20b is connected to a motor 20c (for example, DC The brushless motor is driven in both forward and reverse directions. In the example shown in FIG. 32, when the motor 20c rotates the pulley 20b in a counterclockwise direction, for example, the circulation belt 20a circulates in the direction of the arrow in FIG. 32, and this circulation belt 20a and each pinch roller 20d The paper sheets are conveyed in the right direction.

  In the present embodiment, the control unit 35 controls the motor 20c of the transport unit 20 by the following method. A method for controlling the motor 20c of the transport unit 20 by the control unit 35 will be described with reference to a graph shown in FIG. In the graph shown in FIG. 33, the horizontal axis represents time, and the vertical axis represents the rotational speed of the motor 20c (specifically, the command value of the rotational speed given to the motor 20c of the transport unit 20 by the control unit 35). Show.

When the transport unit 20 is activated, the control unit 35 first rotates the motor 20c at a first rotation speed a (for example, about 1600 rpm). Specifically, the rotation speed command value given to the motor 20c of the transport unit 20 by the control unit 35 is set as the first rotation speed a. The first rotation speed a is a speed at which paper sheets are conveyed at a normal conveyance speed by the circulation belt 20a of the conveyance unit 20 during normal operation. However, since the circulation belt 20a is cured at a low temperature, when the circulation belt 20a is driven at such a low temperature, the command value of the rotation speed given to the motor 20c of the transport unit 20 by the control unit 35 is the first value. Even when the rotation speed is a, the actual rotation speed of the motor 20c may not reach the first rotation speed a. For this reason, after the command value of the rotational speed given to the motor 20c of the transport unit 20 by the control unit 35 is set to the first rotational speed a, the actual value of the motor 20c is passed even if a predetermined time (for example, 2 seconds) elapses. when the rotational speed is in the case of not reaching the first rotation speed a which (see time t ₁ in FIG. 33), each component unit in the housing 12 of the sheet processing machine 10 is set correctly, the control part 35 temporarily stops the motor 20c (see time _{t 2} in FIG. 33). After the motor 20c is stopped, the predetermined time period (e.g., 1 second) has elapsed (see time t ₃ in FIG. 33), the control unit 35 rotates the motor 20c at a first rotational speed a again (i.e. The command value of the rotational speed given to the motor 20c of the transport unit 20 by the control unit 35 is again set as the first rotational speed a). On the other hand, when the actual rotational speed of the motor 20c does not reach the first rotational speed a and the respective constituent units are not correctly set in the housing 12 of the paper sheet processor 10, the control unit 35 The operation of each component of the sheet processing machine 10 is stopped as an operation failure error, and information indicating that the operation error has occurred is displayed on the operation display unit 36.

After the command value of the rotational speed given to the motor 20c of the transport unit 20 by the control unit 35 is set to the first rotational speed a again, the actual state of the motor 20c even if a predetermined time (for example, 0.8 seconds) elapses. when the rotational speed of the does not reach the first rotation speed a is (see time t ₄ in FIG. 33), rotating the command value of the rotational speed imparted to the motor 20c first conveyer unit 20 by the control unit 35 Decrease from speed a to a second rotational speed b (eg, about 1300 rpm). Then, after the command value of the rotational speed given to the motor 20c of the transport unit 20 by the control unit 35 is reduced to the second rotational speed b, the motor is not changed even if a predetermined time (for example, 1.6 seconds) elapses. If the actual rotational speed of 20c does not become a second rotational speed b (see time t ₅ in FIG. 33), the control unit 35 the operation of the components of the sheet processing machine 10 as malfunction error Is stopped, and information indicating that a malfunction error has occurred is displayed on the operation display unit 36. More specifically, since the second rotational speed b is set to a rotational speed that can be achieved even when the circulating belt 20a is cured to the maximum, the second rotational speed b does not reach the second rotational speed b because the belt is cured. Instead of the cause, it is assumed that a foreign object is caught and an overload is applied, and the operation of the sheet processing machine 10 is stopped as an operation error. On the other hand, after the controller 35 has reduced the rotational speed command value given to the motor 20c of the transport unit 20 to the second rotational speed b, the motor is operated when a predetermined time (for example, 1.6 seconds) elapses. If the actual rotational speed of 20c becomes the second rotational speed b (see time t ₅ in FIG. 33), the control unit 35 further predetermined time motor 20c at a second rotational speed b (e.g., after rotation by 1.4 seconds) (see time t ₆ in FIG. 33), the command value of the rotational speed imparted to the motor 20c of the conveying unit 20 by the control unit 35 from the second rotational speed b first Increase to rotational speed a.

Then, after setting the rotational speed command value given to the motor 20c of the transport unit 20 by the control unit 35 to the first rotational speed a again, a predetermined time (for example, 0.8 seconds) has passed (see FIG. see time t ₇₎ in 33, the actual rotational speed of the motor 20c is when it reaches the first rotational speed a, the control unit 35 causes the normal operation of the motor 20c at a first rotational speed a. On the other hand, after setting the rotational speed command value given to the motor 20c of the transport unit 20 by the control unit 35 to the first rotational speed a again, the motor 20c even if a predetermined time (for example, 0.8 seconds) elapses. If the actual rotational speed of the does not reach the first rotation speed a is (see time t ₇ in FIG. 33), the control unit 35 a command value of the rotational speed imparted to the motor 20c first conveying section 20 by The rotation speed a is decreased again to the second rotation speed b (for example, 1300 rpm). Such a retry operation for reducing the rotational speed command value given to the motor 20c of the transport unit 20 from the first rotational speed a to the second rotational speed b is at most a predetermined value set in advance. It is performed as many times (for example, 10 times). If the actual rotation speed of the motor 20c does not reach the first rotation speed a even after the above-described retry operation is performed a predetermined number of times, the control unit 35 determines that a paper malfunction error has occurred. The operation of each component of the leaf processor 10 is stopped, and information indicating that a malfunction error has occurred is displayed on the operation display unit 36.

  As described above, in the present embodiment, by performing a retry operation that reduces the command value of the rotational speed given to the motor 20c of the transport unit 20 from the first rotational speed a to the second rotational speed b. Since the circulation belt 20a can be circulated and moved at a low speed, even when the circulation belt 20a is cured at a low temperature, the circulation belt 20a is softened without overloading the motor 20c, so that the conveying unit 20 It becomes possible to perform the steady operation. That is, in the conventional method for controlling the motor 20c of the transport unit 20, even when the command value of the rotational speed given to the motor 20c of the transport unit 20 by the control unit 35 when the transport unit 20 is started is used as the first rotational speed a. If the actual rotation speed of 20c does not reach the first rotation speed a, the command value of the rotation speed given to the motor 20c of the transport unit 20 is not decreased from the first rotation speed a, but instead, a malfunction error occurs. As a result, the operation of each component of the paper sheet processing machine 10 is stopped. Thus, in the prior art, since the operation of softening the circulation belt 20a by circulating the circulation belt 20a at a low speed has not been performed, the motor 20c is prepared in case the circulation belt 20a is cured at a low temperature. However, there is a problem that the cost of the transport unit 20 increases and the installation space of the motor 20c has to be increased. On the other hand, in this embodiment, since the motor 20c can be downsized as compared with the prior art, the cost of the transport unit 20 can be reduced and the installation space of the motor 20c can be reduced. Become. In addition, since the number of retry operations depends on the degree of curing of the circulation belt 20a, the time until the circulation belt 20a becomes a normal operation can be minimized.

  In the present embodiment, as shown in FIG. 16, the identification unit 22 is transported by the first detection unit 22 a and the transport unit 20 that detect a cut portion of the paper sheet transported by the transport unit 20. When the paper sheet conveyed by the second detection unit 22b and the conveyance unit 20 for detecting the position of a predetermined location in the width direction of the paper sheet (for example, the position of the central portion in the width direction of the paper sheet) is a banknote. The 3rd detection part 22c which detects the front and back of the said banknote is provided. Specifically, the identification unit 22 is provided with an image sensor, and an image of the surface of the paper sheet is acquired by the image sensor. The first detection unit 22a detects this when a cut portion is generated in the paper sheet in the image of the surface of the paper sheet acquired by the image sensor. Specifically, the first detection unit 22a detects which of the front edge and the rear edge of the paper sheet is cut in the conveyance direction of the paper sheet by the conveyance unit 20 and conveys the paper sheet. The position of the cut portion in the width direction of the paper sheet conveyed by the unit 20 is detected. The second detector 22b detects the position of a predetermined location in the width direction of the paper sheet based on the image of the surface of the paper sheet acquired by the image sensor. Moreover, the 3rd detection part 22c compares the image of the surface of the banknote acquired by the image sensor, and the image of the front surface of a banknote previously stored in the memory | storage part 37, and the image of a back surface, The front and back of the banknote identified by the identification part 22 is detected. Note that an ultrasonic sensor or a magnetic sensor may be provided instead of providing the image sensor in the identification unit 22. Even when an ultrasonic sensor is provided in the identification unit 22, the presence or position of the cut portion can be detected when a cut portion is generated in the paper sheet. Moreover, when the identification part 22 is provided with the magnetic sensor, the front and back of the banknote can be detected by detecting the position of the thread of the banknote by the magnetic sensor.

  Next, the operation of the paper sheet processing machine 10 of the present embodiment having such a configuration will be described. The operation of the paper sheet processing machine 10 as described below is performed by the control unit 35 controlling each component of the paper sheet processing machine 10.

  When an operator puts one or more sheets into the deposit / withdrawal unit 14 in a stacked state and inputs an instruction to start depositing processing to the control unit 35 through the operation display unit 36, the sheets fed into the deposit / withdrawal unit 14 The sheets are fed one by one to the transport unit 20 by the first feeding mechanism 16, and the sheets are transported one by one by the transport unit 20. Paper sheets conveyed by the conveyance unit 20 are identified by the identification unit 22. Specifically, an image of the surface of the paper sheet is acquired by an image sensor provided in the identification unit 22. The first detection unit 22a detects this when a cut portion is generated in the paper sheet in the image of the surface of the paper sheet acquired by the image sensor. More specifically, the first detection unit 22a detects which of the front edge and the rear edge of the paper sheet is cut in the conveyance direction of the paper sheet by the conveyance unit 20 and conveys the paper sheet. The position of the cut portion in the width direction of the paper sheet conveyed by the unit 20 is detected.

  The first detection unit 22a indicates that the paper sheet identified by the identification unit 22 is normal and that there is no cut portion at the trailing edge of the paper sheet in the transport direction of the paper sheet by the transport unit 20. Is detected, the paper sheet is transported to the temporary storage unit 40 by the transport unit 20. This will be described with reference to a paper sheet S1 shown in FIG. In FIG. 17, the conveyance direction of the paper sheets by the conveyance unit 20 is the right direction. In the paper sheet S1 shown in FIG. 17A, a cut portion T1 is formed at the front edge in the conveyance direction of the conveyance unit 20, but a cut portion is formed at the rear edge in the conveyance direction of the conveyance unit 20. Not.

  Even if such a sheet with no cut portion formed at the trailing edge in the conveyance direction of the conveyance unit 20 is wound around the drum 42 together with the tapes 90, 92, 94 in the temporary storage unit 40, the drum When the paper sheet is fed out from 42, there is no cut portion at the front edge in the paper feeding direction, so that the front edge of the paper sheet as shown in FIGS. 18 (a) and 18 (b). Paper sheets folded by the formed cut portions do not sandwich the tapes 90, 92, 94 from both sides. For this reason, when paper sheets are discharged from the tapes 90, 92, 94 in the vicinity of the guide rollers 50, 52, the paper is near the portion where the paper sheets are discharged from the tapes 90, 92, 94. Leaves won't break or change direction.

  Even when the first detection unit 22a detects that there is a cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, the cut portion in the width direction of the paper sheet Is overlapped with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40, the paper sheet is transported to the temporary storage unit 40 by the transport unit 20. This will be described with reference to a paper sheet S2 shown in FIG. In the paper sheet S2 shown in FIG. 17B, a cut portion T2 is formed at the trailing edge in the transport direction of the transport unit 20, but the position of the cut portion T2 in the width direction of the paper sheet S2 is temporarily held. It overlaps with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the section 40 (specifically, the position of the tape 92).

  Such a sheet in which the position of the cut portion in the width direction overlaps the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40 is the tape 90, 92, 94 in the temporary storage unit 40. At the same time, when the sheet is taken up from the drum 42, when the sheet is fed out from the drum 42, there is a cut portion at the front edge in the sheet feeding direction. Is overlapped with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40, so that when the paper sheet is fed out of the drum 42, the cut portion of the paper sheet is the tape 90, It becomes suppressed by 92,94, and it is suppressed that a paper sheet is folded from this cut part. As a result, when the paper sheets are fed out from the drum 42, the paper sheets folded by the cut portion are prevented from sandwiching the tapes 90, 92, 94 from both sides. , 52, when the paper sheets are discharged from the tapes 90, 92, 94, the paper sheets are torn near the portion where the paper sheets are discharged from the tapes 90, 92, 94. The orientation will not change significantly.

  On the other hand, there is a cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, and the position of the cut portion in the width direction of the paper sheet is the axis of the drum 42 of the temporary storage unit 40. When the first detection unit 22 a detects that the position of each tape 90, 92, 94 in the direction does not overlap, the paper sheet is transported by the transport unit 20 to a place other than the temporary storage unit 40. Specifically, such paper sheets are conveyed to the deposit / withdrawal unit 14 by the conveyance unit 20. This will be described with reference to a paper sheet S3 shown in FIG. The sheet S3 shown in FIG. 17C has a cut portion T3 formed at the trailing edge in the conveyance direction of the conveyance unit 20, and the position of the cut portion T3 in the width direction of the sheet S3 is temporarily held. It does not overlap with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the section 40.

  Such a cut portion is formed at the rear edge in the conveyance direction of the conveyance unit 20, and the position of the cut portion in the width direction is the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. When paper sheets that do not overlap the position are wound around the drum 42 together with the tapes 90, 92, 94 in the temporary storage unit 40, when the paper sheets are fed out from the drum 42, the leading edge in the paper feeding direction As shown in FIGS. 18 (a) and 18 (b), the paper sheets folded by the cut portion formed at the front edge of the paper sheets are tapes 90 and 92, respectively. , 94 may be sandwiched from both sides. In this case, when the paper sheets are discharged from the respective tapes 90, 92, 94 in the vicinity of the respective guide rollers 50, 52, the vicinity of the portion where the paper sheets are discharged from the respective tapes 90, 92, 94. There is a risk that the paper sheets will be torn or the orientation will change greatly. For this reason, it is possible to prevent the occurrence of the above trouble by transporting such paper sheets by the transport unit 20 to a place other than the temporary storage unit 40 (specifically, the deposit / withdrawal unit 14). Will be able to.

  The deposit / withdrawal unit 14 functions as a direction conversion unit for converting the direction of the paper sheet detected by the first detection unit 22a. Specifically, the paper sheet sent from the transport unit 20 to the deposit / withdrawal unit 14 is returned to the transport unit 20 by the second feeding mechanism 18 so that the direction of the paper sheet is changed. A cut portion is formed at the rear edge in the conveyance direction of the conveyance unit 20, and the position of the cut portion in the width direction does not overlap with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. After the paper sheet is sent to the deposit / withdrawal unit 14, when the sheet is returned from the deposit / withdrawal unit 14 to the transport unit 20 by the second feeding mechanism 18, the direction of the paper sheet returned to the transport unit 20 ( Specifically, the orientation of the paper sheet in the transport direction by the transport unit 20 is converted. Specifically, the front edge and the rear edge of the paper sheet are interchanged in the direction in which the paper sheet is transported by the transport unit 20. Then, the paper sheet returned from the deposit / withdrawal unit 14 to the transport unit 20 is sent again to the identification unit 22, and is identified by the identification unit 22. At this time, when there is no cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20 (see the paper sheet S1 in FIG. 17A), or the paper sheet by the conveyance unit 20 Although there is a cut portion at the trailing edge of the paper sheet in the paper transport direction, the position of the cut portion in the paper width direction is the tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. (See the paper sheet S2 in FIG. 17B), these paper sheets are conveyed to the temporary storage unit 40. Note that when the paper sheets returned from the deposit / withdrawal unit 14 to the transport unit 20 are sent again to the identification unit 22 and identified by the identification unit 22, the transport of the paper sheets by the transport unit 20 is still performed. And the position of the cut portion in the width direction of the paper sheet corresponds to the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. If they do not overlap, the paper sheet is sent again to the depositing / dispensing section 14 as reject paper sheet and taken out by the operator.

  Note that a cut portion is formed at the rear edge in the transport direction of the transport unit 20, and the position of the cut portion in the width direction is the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. When non-overlapping paper sheets are sent to the deposit / withdrawal unit 14, such sheets are returned from the deposit / withdrawal unit 14 by the operator instead of being returned to the transport unit 20 by the second feeding mechanism 18. Is taken out, and after the direction of the taken-out paper sheet is changed, it is again inserted into the depositing / dispensing unit 14 by the operator and fed out to the conveying unit 20 by the first feeding mechanism 16 of the depositing / dispensing unit 14. It may be. At this time, a guidance message for re-inserting paper sheets may be displayed on the operation display unit 36. Specifically, the lower end of the paper sheet returned to the deposit / withdrawal unit 14 becomes the lower end even when the paper is re-inserted so that the cut portion of the paper sheet re-input is positioned at the front edge in the transport direction. A guidance message for re-inserting paper sheets may be displayed on the operation display unit 36. As described above, when the paper sheets are re-input into the deposit / withdrawal unit 14 and are fed out to the transport unit 20 by the first feeding mechanism 16 of the deposit / withdrawal unit 14, the paper sheets are again sent to the identification unit 22, Identification is performed by the identification unit 22.

  After all the sheets put into the deposit / withdrawal unit 14 by the operator are fed out from the deposit / withdrawal unit 14 to the transport unit 20 and temporarily held in the temporary storage unit 40, the operator uses the operation display unit 36. When an approval command is given to the control unit 35, the paper sheets are rewound from the drum 42 together with the tapes 90, 92, 94, whereby the paper sheets are fed from the temporary storage unit 40 to the transport unit 20 one by one. The paper sheet fed to the section 20 is transported by the transport section 20 to each paper sheet storage / feeding section 30 or each paper sheet storage / feeding section 32. When all the paper sheets temporarily held in the temporary storage unit 40 are stored in each paper sheet storage / feeding unit 30 or each paper sheet storage / feeding unit 32, the paper sheets in the paper sheet processing machine 10 are stored. The storing operation is completed.

  In the present embodiment, the control unit 35 sets the transport destination of the paper sheet between the temporary storage unit 40 and other locations based on the position of the cut portion of the paper sheet detected by the first detection unit 22a. In controlling the transport unit 20 so as to switch between them, a control method other than the above control method may be performed. As another aspect of the control method by the control unit 35, for example, the paper sheet identified by the identification unit 22 is normal, and the rear end of the paper sheet in the transport direction of the paper sheet by the transport unit 20. When the first detection unit 22a detects that there is a cut portion at the edge, regardless of the position of the cut portion in the width direction of the paper sheet (that is, in the width direction of the paper sheet) Even when the position of the cut portion overlaps the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40, the sheet is transported by the transport unit 20 at a location other than the temporary storage unit 40 (specifically, May be transported to the deposit / withdrawal unit 14).

  According to the paper sheet storage and feeding device (specifically, the temporary storage unit 40) of the present embodiment configured as described above, the tapes 90, 92, and 94 are rewound from the drum 42, thereby Guide sections 80 and 85 are provided for guiding the paper sheets so as to prevent the paper sheets from pinching the tapes 90, 92 and 94 from both sides when the paper sheets are fed out from the drum 42. By providing such guide portions 80 and 85, even when the paper sheets are folded when the paper sheets are fed out from the drum 42, the folded paper sheets are respectively transferred to the tapes 90 and 92. , 94 is prevented from being sandwiched from both sides by the guide portions 80, 85, so that the vicinity of the portion where the paper sheets are discharged from the tapes 90, 92, 94 (specifically, the guide rollers 50, 52), it is possible to prevent the paper sheets from being torn or the direction from being greatly changed.

  Further, in the paper sheet storage and feeding device according to the present embodiment, as described above, the guide portions 80 and 85 are positioned so that the positions of the drums 42 in the axial direction face the tapes 90, 92, and 94. ing. Here, the guide portion 80 facing the central tape 92 is folded when the paper sheets are fed out from the drum 42 by rewinding the tapes 90, 92, 94 from the drum 42. This portion is shaped so as to move away from the tape 92 in the axial direction of the drum 42. More specifically, the guide portion 80 has a shape in which the width in the axial direction of the drum 42 gradually increases in the direction in which the paper sheets are fed from the drum 42. Further, the guide portions 85 facing the tapes 90 and 94 on both sides have opposite end edges of the drum 42 so that the width in the axial direction of the drum 42 is constant in the direction in which the sheets are fed out from the drum 42. It has a shape extending along the circumferential direction.

  In the paper sheet storage and feeding device of the present embodiment, as described above, a plurality of tapes 90, 92, 94 are provided so as to be aligned along the axial direction of the drum 42. A plurality of guide portions (specifically, the guide portion 80 and each guide portion 85) are provided corresponding to 94.

  In the paper sheet storage and feeding device of the present embodiment, as described above, when the tapes 90, 92, and 94 are wound around the drum 42, the paper sheets are stored in the drum 42. An additional guide part 86 for guiding the paper sheet is provided, and the additional guide part 86 is swingable about the shaft 83 in accordance with the amount of the paper sheet stored in the drum 42. ing. Specifically, the movable guide 82 provided with the additional guide portion 86 is swingable about the shaft 83 according to the amount of paper sheets stored in the drum 42. The guide portion 85 is attached to such an additional guide portion 86. In this case, whether the amount of paper sheets stored in the drum 42 is large or small, the space between the guide surface 85a of each guide portion 85 and the surface of each tape 90, 94 wound around the drum 42 is not limited. The gap can be reduced. In this case, the guide portion 85 is disposed so as to protrude toward the drum 42 from the guide surface 86a for guiding the paper sheets in the additional guide portion 86.

  Further, in the paper sheet storage and feeding device according to the present embodiment, as described above, the guide unit 80 facing the central tape 92 has the shaft 81 according to the amount of paper sheets stored in the drum 42. The guide part 80 can be brought into contact with a tape 92 wound around the drum 42.

  Further, in the paper sheet storage and feeding device according to the present embodiment, as described above, the drum 42, the guide roller 50, and the guide roller 50 are provided in the vicinity of the guide roller 50 that guides the tapes 90 and 94 rewound from the drum 42. A scraper member 96 that is in contact with each of the tapes 90 and 94 is provided as a take-up member guide portion. The scraper member 96 is configured such that paper sheets rewound from the drum 42 are guided by the guide roller 50 and each tape. The shape is such that it is prevented from entering between 90 and 94. More specifically, the scraper member 96 has such a shape as to prevent paper sheets rewound from the drum 42 from entering between the scraper member 96 and the tapes 90 and 94. By providing such a scraper member 96, when the tapes 90, 92, 94 are rewound from the drum 42 and the paper sheets are fed out from the drum 42, in the paper feeding direction. Even when there is a cut portion at the front edge of the paper sheet, even if a part of the paper sheet is detached from the tapes 90, 92, 94 wound around the drum 42 due to the cut portion, the paper sheet Can be prevented from entering between the scraper member 96 and each of the tapes 90 and 94, and if the paper sheet is removed, the scraper member 96 and the tapes 90 and 94 Even if it enters between the gaps, it is possible to prevent the removed portion from being fed between the guide roller 50 and the tapes 90 and 94.

  Here, the scraper member 96 is shaped to cover at least one side edge of each of the tapes 90 and 94 that are in contact with the scraper member 96. More preferably, the scraper member 96 is shaped to cover both side edges of the tapes 90 and 94 that are in contact with the scraper member 96. In addition, the scraper member 96 has such a shape that the cross-sectional shape of each of the tapes 90 and 94 in contact with the scraper member 96 is deformed from a linear shape.

  Further, according to the paper sheet processor 10 according to the present embodiment configured as described above, the control unit 35 is based on the position of the cut portion of the paper sheet detected by the first detection unit 22a. The transport unit 20 is configured to switch the transport destination of the paper sheet detected by the first detection unit 22a between the paper sheet storage and feeding device (specifically, the temporary storage unit 40) and other locations. Control is to be performed. As described above, by detecting the position of the cut portion of the paper sheet by the first detection unit 22a before the paper sheet is conveyed to the paper sheet storage and feeding device, the paper has a cut portion at a predetermined position. For paper sheets that may be torn at the exit or change direction greatly when fed out from the sheet storage and feeding device, this paper is prevented from being conveyed to the paper sheet storage and feeding device. It is possible to prevent the paper sheets from staying at the exit portion of the leaf storage and feeding device.

  In particular, the paper sheet storing and feeding device has a tape type in which one end of each of the strip-shaped tapes 90, 92, 94 for winding a plurality of paper sheets one by one is connected to the outer peripheral surface thereof. In the case of the paper sheet storing and feeding device, among the paper sheets detected by the first detection unit 22a, the tapes 90, 92 and 94 are sandwiched from both sides when the paper sheets are fed from the drum 42. Thus, it is possible to prevent the paper sheet on which the cut portion causing the crease is formed from being sent to the tape-type paper sheet storage and feeding device.

  In the paper sheet processing machine 10 according to the present embodiment, when the control unit 35 performs the above control, the paper sheet storage and feeding device as a paper sheet transport destination includes a plurality of paper sheets. It is not limited to a tape-type paper sheet storing and feeding device in which one end of each of the strip-shaped tapes 90, 92, and 94 for winding up one by one has a drum 42 connected to the outer peripheral surface thereof. In the paper sheet processing machine 10 according to another aspect, the control unit 35 is detected by the first detection unit 22a based on the position of the cut portion of the paper sheet detected by the first detection unit 22a. A paper sheet storage / delivery device having a configuration other than a tape-type paper sheet storage / delivery device (for example, a paper sheet storage / delivery unit 30, 32) is stacked in a stacked state. The conveyance unit 20 may be controlled so as to switch between a stacker-type paper sheet storage and feeding device) and other portions.

  Further, in the paper sheet processing machine 10 of the present embodiment, as described above, the control unit 35 has a cut portion at the trailing edge of the paper sheet in the transport direction of the paper sheet by the transport unit 20. If not, the transport unit 20 may be controlled to transport the paper sheet detected by the first detection unit 22a to the paper sheet storage and feeding device. On the other hand, when there is a cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, the control unit 35 detects the paper sheet detected by the first detection unit 22a. The transport unit 20 may be controlled to transport the paper to a place other than the paper sheet storage and feeding device. In this case, when there is a cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, the control unit 35 detects the paper sheet detected by the first detection unit 22a. The transport unit 20 is controlled so as to transport the paper to the direction changing unit (specifically, the deposit / withdrawal unit 14) for changing the direction of the paper sheet. Here, the depositing / dispensing unit 14 as the direction changing unit is provided with a second feeding mechanism 18 that feeds the sheets sent to the depositing / dispensing unit 14 to the transporting unit 20. The paper sheets sent to the section 14 are returned to the transport section 20 by the second feeding mechanism 18 so that the direction of the paper sheets is changed.

  Further, as described above, the control unit 35 conveys the paper sheet fed from the deposit / withdrawal unit 14 as the direction changing unit to the conveyance unit 20 by the second feeding mechanism 18 to the first detection unit 22a, and When the first detection unit 22a detects the cut portion of the paper sheet again, and there is no cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, the first detection unit 22a The transport unit 20 is controlled so as to transport the paper sheet detected by the above to the paper sheet storage and feeding device.

  In addition, when there is a cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, the control unit 35 detects the paper sheet detected by the first detection unit 22a. Is transferred to the depositing / withdrawing unit 14 by controlling the conveying unit 20 so that the sheet is conveyed to the depositing / dispensing unit 14 provided with a dispensing port for throwing out the sheet out of the body of the sheet processing machine 10. The direction of the paper sheets may be manually changed by the operator.

  Further, in the paper sheet processing machine 10 of the present embodiment, as described above, the control unit 35 has a cut portion at the trailing edge of the paper sheet in the transport direction of the paper sheet by the transport unit 20. Even in this case, the position of the cut portion in the width direction of the paper sheet is the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the paper sheet storage and feeding device (specifically, the temporary storage unit 40). In the case where it overlaps, the transport unit 20 may be controlled to transport the paper sheet detected by the first detection unit 22a to the paper sheet storage and feeding device. On the other hand, when there is a cut portion at the trailing edge of the paper sheet in the conveyance direction of the paper sheet by the conveyance unit 20, the control unit 35 determines the position of the cut portion in the width direction of the paper sheet. When the sheet is not overlapped with the position of each of the tapes 90, 92, 94 in the axial direction of the drum 42 of the sheet storing and feeding device, the sheet detected by the first detection unit 22a is placed at a location other than the sheet storing and feeding device. The conveyance unit 20 may be controlled so as to be conveyed.

  Note that the paper sheet processing machine 10 according to the present embodiment and the paper sheet storage and feeding device (specifically, the temporary storage unit 40) provided in such a paper sheet processing machine 10 are as described above. It is not limited to an aspect, A various change can be added.

  For example, the identification unit 22 is not provided with the first detection unit 22a that detects a cut portion of the paper sheet conveyed by the conveyance unit 20, but instead the conveyance unit 20 is detected by the second detection unit 22b. The position of a predetermined location in the width direction of the paper sheet being conveyed by (for example, the position of the central portion in the width direction of the paper sheet) may be detected. In such a case, the control unit 35 detects the sheet detected by the second detection unit 22b based on the position of the predetermined position in the width direction of the sheet detected by the second detection unit 22b. The transport unit 20 is controlled so that the transport destination is switched between the paper sheet storage and feeding device (specifically, the temporary storage unit 40) and other locations. More specifically, the control unit 35 determines that the position of a predetermined location in the width direction of the paper sheet (for example, the position of the central portion in the width direction of the paper sheet) is the temporary storage unit 40 as the paper sheet storage and feeding device. When the position of each tape 90, 92, 94 in the axial direction of the drum 42 overlaps, the transport unit 20 is controlled to transport the paper sheet detected by the second detection unit 22b to the temporary storage unit 40. To do. On the other hand, the controller 35 determines that the position of a predetermined location in the width direction of the paper sheet (for example, the position of the central portion in the width direction of the paper sheet) is the tape 90 in the axial direction of the drum 42 of the temporary storage unit 40, If it does not overlap the positions 92 and 94, the transport unit 20 is configured to transport the paper sheets detected by the second detection unit 22b to a place other than the temporary storage unit 40 (for example, the deposit / withdrawal unit 14). Control.

  Here, in the paper sheet processing machine 10 according to the present embodiment, regarding the paper sheets that are put into the deposit / withdrawal unit 14 by the operator, when the period in which the paper is on the market is long, the paper sheets have their width many times. By being folded at the position of the central portion in the direction, there is a possibility that a cut portion is generated at this position. On the other hand, even when the identification unit 22 cannot detect the cut portion itself formed on the paper sheet with respect to the paper sheet put into the casing 12 of the paper sheet processing machine 10, the identification unit 22 By detecting the position of the central portion in the width direction of the paper sheet by using the second detection unit 22b provided in the paper sheet, the position of the cut portion formed on the paper sheet can be estimated. That is, by detecting the position of the central portion in the width direction of the paper sheet conveyed by the conveyance unit 20 by the second detection unit 22b, it is considered that a cut portion is formed at this position. This makes it possible to sort the transport destination of a kind to a place other than the temporary holding unit 40 and the temporary holding unit 40. In other words, even when the identification unit 22 cannot detect the cut portion itself formed on the paper sheet, by assuming that the cut portion is formed at the position of the central portion in the width direction of the paper sheet, Among the paper sheets in which the cut portion is formed at the position of the central portion in the width direction, the cut portion does not overlap with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. Such paper sheets can be prevented from being sent to the temporary storage unit 40. As a result, when paper sheets are discharged from the tapes 90, 92, 94 in the vicinity of the guide rollers 50, 52, in the vicinity of locations where the paper sheets are discharged from the tapes 90, 92, 94. It becomes possible to prevent the occurrence of the problem that the paper sheets are torn or the direction is greatly changed.

  Further, when the paper sheet detected by the second detection unit 22b is conveyed to the deposit / withdrawal unit 14 instead of the temporary storage unit 40, the second delivery mechanism 18 transfers the paper sheet from the deposit / withdrawal unit 14 to the conveyance unit 20. You may make it return paper sheets. Here, when the paper sheets are fed from the deposit / withdrawal section 14 to the transport section 20 by the second feeding mechanism 18, the position of the paper sheets in the width direction may change, so the paper returned to the transport section 20 When the leaf is detected again by the second detection unit 22b, the position of the central portion in the width direction of the paper sheet overlaps with the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. Sometimes it becomes. In such a case, the paper sheet detected by the second detection unit 22b is conveyed to the temporary storage unit 40. In addition, when the paper sheet detected by the second detection unit 22b is conveyed to the deposit / withdrawal unit 14, the operator takes out the paper sheet from the deposit / withdrawal unit 14, and the width direction of the paper sheet The paper sheets may be fed out to the transport unit 20 by the first feeding mechanism 16 by inserting the paper sheets into the depositing / dispensing unit 14 again while shifting the position. Even when such an operation is performed, the position of the paper sheet fed to the transport unit 20 by the first feeding mechanism 16 in the width direction changes, so that the paper sheet returned to the transport unit 20 2 When the detection is performed again by the detection unit 22b, the position of the central portion in the width direction of the paper sheet may overlap the position of each tape 90, 92, 94 in the axial direction of the drum 42 of the temporary storage unit 40. is there.

  Moreover, when the deposit processing of a banknote is performed in the paper sheet processing machine 10 by this Embodiment, the banknote identified by the identification part 22 is not sent to the temporary storage part 40, but to each paper sheet storage and feeding part 30 It may be stored directly. In this case, when a banknote fed out from the deposit / withdrawal unit 14 to the transport unit 20 by the first feeding mechanism 16 is identified by the identification unit 22, the front and back of the banknote is detected by the third detection unit 22 c provided in the identification unit 22. Is detected, and based on the front and back information of the banknote detected by the third detection unit 22c, the control unit 35 sets the transport destination of the banknote detected by the third detection unit 22c to each paper sheet storage and feeding unit 30. And the other part (for example, depositing / withdrawing part 14), you may control the conveyance part 20 so that it may switch. More specifically, when the bill processed by the paper sheet processor 10 includes a 100 dollar bill issued in the United States or a 50,000 won bill issued in the Republic of Korea, the third detector 22c is set. The above-described processing is performed. A strip-shaped 3D security ribbon is formed on the surface of a 100 dollar bill to prevent forgery, and a three-dimensional partially exposed silver wire is formed on the surface of a 50,000 won bill to prevent forgery. (For example, refer to FIG. 6A of Japanese Patent No. 5508990). When such a bill having a 3D structure forgery prevention member formed on its surface is stacked in a stacked state on each paper sheet storage and feeding unit 30, it is already stacked on each paper sheet storage and feeding unit 30 If the surface on which the anti-counterfeit member is formed is facing upward in the uppermost banknote, the banknote is already stacked when the next banknote is stacked on the paper sheet storage and feeding unit 30. There is a possibility that the counterfeit prevention member of the uppermost banknote is caught and the banknote cannot be accumulated in the paper sheet storage and feeding unit 30 and troubles such as clogging may occur. For this reason, when the banknote which should be sent to each paper sheet storage and feeding part 30 from the conveyance part 20 is identified by the identification part 22, it is the 3rd detection that the forgery prevention member formed in the said banknote is facing upward. When detected by the unit 22c, the banknote is not accumulated in each paper sheet storage and feeding unit 30, but is sent to the depositing / dispensing unit 14, for example. Moreover, in this case, since the surface provided with the forgery prevention member in the banknote sent to the deposit / withdrawal unit 14 is in the same direction, the deposit / withdrawal unit 14 does not cause a stacking failure of banknotes.

  Moreover, after the banknote detected by the 3rd detection part 22c is sent to the deposit or withdrawal part 14, if a banknote is returned to the conveyance part 20 by the 2nd feeding mechanism 18 from the said deposit or withdrawal part 14, the front and back of this banknote will be It will be reversed. As described above, the transport unit 20 and the deposit / withdrawal unit 14 constitute a front / back conversion unit that converts the front / back side of the banknote detected by the third detection unit 22c. When the front / back direction of the banknote detected by the third detection unit 22c is not a predetermined direction, the control unit 35 converts the front / back side of the banknote detected by the third detection unit 22c into a front / back conversion unit (specifically). Specifically, the transport unit 20 and the deposit / withdrawal unit 14 are controlled so as to be converted by the transport unit 20 and the deposit / withdrawal unit 14). And the control part 35 conveys the banknote by which the front and back conversion part was converted to the 3rd detection part 22c, makes the 3rd detection part 22c detect the front and back of a banknote again, and is detected by the 3rd detection part 22c. When the direction of the front and back of the banknotes becomes a predetermined direction, the transport unit 20 is controlled so that the banknotes detected by the third detection unit 22c are transported to each paper sheet storage and feeding unit 30. Thus, when the direction of the front and back of the banknote detected by the 3rd detection part 22c is not a predetermined direction (specifically, when a forgery prevention member is accumulated in each paper sheet storage and feeding part 30, When the paper is turned upside down), the front and back conversion unit converts the front and back of the bill so that the forgery prevention member of the bill when stacked in each paper sheet storage and feeding unit 30 can be faced down. Thus, troubles such as banknote jams can be prevented from occurring in each paper sheet storage and feeding section 30.

  Further, the paper sheet storage and feeding device (specifically, the temporary storage unit) provided in the paper sheet processing machine 10 according to the present embodiment is limited to the one having the configuration as shown in FIGS. Never happen. FIG. 20 and FIG. 21 show a tape-type paper sheet storage and feeding device that stores paper sheets such as banknotes one by one in a rotating body such as a drum and feeds paper sheets one by one from the rotating body. You may use the temporary storage part 40a of a structure as shown. 20 and FIG. 21 is different from the guide unit 80 of the temporary storage unit 40 shown in FIGS. 2 to 15 only in the configuration of the guide unit 80p, and other components are shown in FIGS. 15 has substantially the same configuration as the temporary holding unit 40 shown in FIG. Therefore, in describing the temporary storage unit 40a shown in FIGS. 20 and 21, the same components as those of the temporary storage unit 40 shown in FIGS. 2 to 15 are denoted by the same reference numerals and description thereof is omitted. .

  In the temporary holding portion 40a shown in FIGS. 20 and 21, a guide portion 80p is provided above the drum 42 such that the tip portion covers all of the three tapes 90, 92, 94. In FIG. 20, the drum 42 is not shown in order to make it easy to see the positional relationship between the guide portion 80p and the tapes 90, 92, and 94. Here, the guide portion 80p is rotatable about a shaft 81p extending in parallel with the shaft 42a of the drum 42. The leading end portion of the guide portion 80p comes into contact with the tapes 90, 92, and 94 wound around the drum 42 by the weight of the guide portion 80p. Note that the guide portion 80p has its tip end portion in contact with the tapes 90, 92, and 94 wound around the drum 42 by its own weight, but the tip portion of the guide portion 80p is pressed by the biasing means such as a spring (not shown). It may be biased toward the side. Since the guide portion 80p having such a configuration is provided so as to be opposed to the tapes 90, 92, and 94 and to come into contact with the surfaces of the tapes 90, 92, and 94, the respective tapes 90, 92, and 94 are started from the drum. When the paper sheet is unwound from the drum 42 by being rewound, even if the folded part of the paper sheet tries to get on the surface of each tape 90, 92, 94, the folded part of the paper sheet is By contacting the guide portion 80p, the portion is prevented from getting on the surface of each of the tapes 90, 92, and 94. As a result, the folded paper sheets sandwich the tapes 90, 92, and 94 from both sides. Is prevented.

  Further, as shown in FIG. 20, the leading end portion of the guide portion 80p is disposed below each tape 90, 94 that moves between the drum 42 and the guide roller 56, and the leading end portion of the guide portion 80p is The tapes 90 and 94 moving between the drum 42 and the guide roller 56 are opposed to each other with a slight gap. As described above, in the temporary storage unit 40a shown in FIGS. 20 and 21, the drum 42 rotates from the guide roller 56 to the drum 42 when the sheet rotates from the drum 42 in the clockwise direction in FIG. The guide portions 80p and the guide portions 85 are disposed on both sides of the tapes 90 and 94 sent to the tape. In this case, even if the paper sheets are folded when the paper sheets are fed out from the drum 42, the folded paper sheets may pinch the tapes 90 and 94 from both sides. Since it is more reliably prevented by 80p and 85, the paper sheet may be torn near the portion where the paper sheet is discharged from the tapes 90 and 94 (specifically, the guide rollers 50 and 52). It can suppress more reliably that direction changes greatly.

  Further, as another configuration of the tape-type paper sheet storing and feeding device that stores paper sheets such as banknotes one by one in a rotating body such as a drum and feeds paper sheets one by one from the rotating body. Alternatively, a temporary holding unit 40b configured as shown in FIG. 22 may be used. The temporary holding section 40b shown in FIG. 22 is provided with a plurality of (specifically, three) guide sections 80q corresponding to the respective tapes 90, 92, 94. It is only different from the guide part 80 of the holding | maintenance part 40, and it has the structure substantially the same as the temporary storage part 40 shown in FIG. 2 thru | or FIG. For this reason, in describing the temporary storage unit 40b shown in FIG. 22, the same components as those of the temporary storage unit 40 shown in FIGS.

  In the temporary holding portion 40b shown in FIG. 22, three guide portions 80q are provided above the drum 42 corresponding to the three tapes 90, 92, 94. In FIG. 22, the drum 42 is not shown in order to make it easy to see the positional relationship between the guide portions 80 q and the tapes 90, 92, and 94. Here, each guide portion 80q is rotatable about a shaft 81q extending in parallel with the shaft 42a of the drum 42. The leading end portions of the guide portions 80q come into contact with the tapes 90, 92, and 94 wound around the drum 42 by their own weights. Each guide portion 80q has its leading end portion contacted with each of the tapes 90, 92, 94 wound around the drum 42 by its own weight, instead of the leading end portion of each guiding portion 80q by a biasing means such as a spring (not shown). May be biased toward the drum 42 side. Since each guide portion 80q having such a configuration is provided so as to be opposed to each tape 90, 92, 94 and to contact the surface of these tapes 90, 92, 94, each tape 90, 92, 94, When the sheet is unwound from the drum 42 by unwinding 94, even if the folded portion of the paper sheet tries to get on the surface of each tape 90, 92, 94, the folded portion of the paper sheet Contact with each guide portion 80q prevents the portion from getting on the surface of each tape 90, 92, 94, which allows folded paper sheets to attach each tape 90, 92, 94 from both sides. It is prevented from being caught.

  Further, as shown in FIG. 22, the tip portions of the guide portions 80q corresponding to the tapes 90 and 94 are disposed below the tapes 90 and 94 that move between the drum 42 and the guide roller 56, respectively. The leading end portions of the guide portions 80q are opposed to the tapes 90 and 94 moving between the drum 42 and the guide roller 56 with a slight gap therebetween. As described above, in the temporary storage unit 40b shown in FIG. 22, when the paper sheets are fed out from the drum 42, the paper is fed from the guide roller 56 to the drum 42, similarly to the temporary storage unit 40a shown in FIGS. About each tape 90 and 94, the guide part 80q and the guide part 85 come to be arrange | positioned at the both sides, respectively. In this case, even if the paper sheets are folded when the paper sheets are fed out from the drum 42, the folded paper sheets may pinch the tapes 90 and 94 from both sides. Since it is more reliably prevented by 80q and 85, the paper sheet is torn near the portion where the paper sheet is discharged from the tapes 90 and 94 (specifically, the guide rollers 50 and 52). It can suppress more reliably that direction changes greatly.

  Further, as another configuration of the tape-type paper sheet storing and feeding device that stores paper sheets such as banknotes one by one in a rotating body such as a drum and feeds paper sheets one by one from the rotating body. Alternatively, a temporary holding unit 40c configured as shown in FIG. 23 may be used. The temporary holding unit 40c shown in FIG. 23 is different from the temporary holding unit 40 shown in FIGS. 2 to 15 only in that a plurality of guide units 80r are additionally provided corresponding to the tapes 90 and 94, respectively. The other components are substantially the same as the temporary holding unit 40 shown in FIGS. Therefore, in describing the temporary storage unit 40c shown in FIG. 23, the same reference numerals are given to the same components as those of the temporary storage unit 40 shown in FIGS. 2 to 15, and the description thereof is omitted.

  In the temporary holding unit 40c shown in FIG. 23, as in the temporary holding unit 40 shown in FIGS. 2 to 15, a guide unit 80 is installed above the drum 42 corresponding to the central tape 92. 80 is rotatable about a shaft 81 extending in parallel with the shaft 42 a of the drum 42. The leading end portion of the guide portion 80 comes into contact with the tape 92 wound around the drum 42 by its own weight. Further, the guide portion 80 has a position in the axial direction of the drum 42 (that is, a position in a direction orthogonal to the paper surface of FIG. 23) facing the tape 92. Further, in the temporary holding portion 40c shown in FIG. 23, two guide portions 80r are provided above the drum 42 corresponding to the tapes 90 and 94 on both sides (in FIG. 23, only one guide portion 80r is provided). However, in practice, two guide portions 80r are provided so as to be aligned along a direction orthogonal to the paper surface of FIG. 23). These guide portions 80r are rotatable about a shaft 81r provided on the left side in FIG. The leading end portions of the guide portions 80r come into contact with the tapes 90 and 94 wound around the drum 42 by the weight of each guide portion 80r. Each guide portion 80r has its tip portion contacted with each of the tapes 90 and 94 wound around the drum 42 by its own weight. It may be biased toward the drum 42 side. Since each guide portion 80r having such a configuration is provided so as to face the tapes 90 and 94 and come into contact with the surfaces of the tapes 90 and 94, the tapes 90 and 94 are rewound from the drum 42. When the paper sheet is fed out from the drum 42 by this, even if the folded part of the paper sheet tries to get on the surface of each tape 90, 94, the folded part of the paper sheet contacts each guide portion 80r. As a result, it is possible to prevent the folded portion from getting on the surfaces of the tapes 90 and 94, thereby preventing the folded paper sheets from sandwiching the tapes 90 and 94 from both sides. become.

  Further, as another configuration of the tape-type paper sheet storing and feeding device that stores paper sheets such as banknotes one by one in a rotating body such as a drum and feeds paper sheets one by one from the rotating body. A configuration as shown in FIG. 24 may be used. 24 is a side view showing the configuration of the paper sheet storage and feeding device 140 according to the present invention, and FIG. 25 is a side view showing the configuration of the conventional paper sheet storage and feeding device 140a as a comparative example. FIG.

  As shown in FIG. 24, the paper sheet storage and feeding device 140 according to the present invention is configured such that the pair of tapes 150 and 152 is drum 142 in a state where the paper sheets are sandwiched between the pair of strip-shaped tapes 150 and 152. A plurality of paper sheets are housed in the drum 142 one by one by winding up, and a pair of tapes 150 and 152 are rewound from the drum 142 to unwind the paper sheets one by one from the drum 142. Consists of formulas. Specifically, the paper sheet storage and feeding device 140 includes a drum 142 that is rotatable, a pair of belt-like tapes 150 and 152 each having one end connected to the outer peripheral surface of the drum 142, and a rotatable drum 142. The first tape reel 144 having the other end of one tape 150 connected to the outer peripheral surface of the pair of strip-shaped tapes 150 and 152 and the pair of strip-shaped tapes 150 and 152 are rotatable. The other end of the other tape 152 has a second tape reel 146 connected to the outer peripheral surface thereof.

  The drum 142 can rotate in both the clockwise direction and the counterclockwise direction in FIG. 24 about the shaft 142a. Specifically, when the paper sheets sent from the outside of the paper sheet storage and feeding device 140 to the inside of the paper sheet storage and feeding device 140 through the entrance / exit 158 are stored in the drum 142, the drum 142 24 rotates in the counterclockwise direction in FIG. 24, and the pair of tapes 150 in a state where a sheet fed between the pair of strip-shaped tapes 150 and 152 from the entrance / exit 158 is sandwiched between the tapes 150 and 152. , 152 and the paper sheets are wound around the drum 142. On the other hand, when the paper sheets stored in the drum 142 are fed out of the paper sheet storage and feeding device 140 through the entrance / exit 158, the drum 142 rotates in the clockwise direction in FIG. By rewinding the pair of tapes 150 and 152, the paper sheets sandwiched between the pair of tapes 150 and 152 are released and sent to the entrance / exit 158.

  Further, as shown in FIG. 24, a drive motor 148 for rotating the drum 142 is provided. More specifically, a pulley (not shown) is connected to the drive motor 148 via a rotating shaft, and a drive belt (not shown) is stretched over the pulley. A pulley (not shown) is also connected to the shaft 142a of the drum 142, and the drive belt is stretched around the pulley. As a result, when the drive motor 148 rotates the drive belt, the rotational driving force by the drive motor 148 is transmitted to the shaft 142a via the drive belt, and the drum 142 is driven to rotate.

  The other end of one of the pair of strip-shaped tapes 150 and 152 is connected to the outer peripheral surface of the first tape reel 144 so that the tape 150 is wound around the first tape reel 144. It has become. Further, the first tape reel 144 can rotate in both the clockwise direction and the counterclockwise direction in FIG. 24 about the shaft 144a. Here, when the first tape reel 144 rotates in the counterclockwise direction in FIG. 24, the tape 150 is wound around the first tape reel 144, while the first tape reel 144 is wound. 24 is rotated in the clockwise direction in FIG. 24, whereby the tape 150 wound around the first tape reel 144 is rewound.

  The other end of the other tape 152 is connected to the outer peripheral surface of the second tape reel 146 so that the tape 152 is wound around the second tape reel 146. It has become. Further, the second tape reel 146 can be rotated around the shaft 146a in both the clockwise direction and the counterclockwise direction in FIG. Here, by rotating the second tape reel 146 in the clockwise direction in FIG. 24, the tape 152 is wound around the second tape reel 146, while the second tape reel 146 is rotated. By rotating in the counterclockwise direction in FIG. 24, the tape 152 wound around the second tape reel 146 is rewound.

  Further, in the vicinity of the entrance / exit 158 of the paper sheet storage and feeding device 140, a guide roller 154 for guiding the tape 150 and a guide roller 156 for guiding the tape 152 are arranged to face each other with a slight gap. The paper sheets sent from the outside of the paper sheet storage and feeding device 140 to the inside of the paper sheet storage and feeding device 140 through the entrance / exit 158 pass between the guide rollers 154 and 156, The drum 150 is wound around the drum 142 between the tapes 150 and 152.

  As shown in FIG. 24, a movable guide 170 is provided below the drum 142. The movable guide 170 rotates about a shaft 171 provided coaxially with the shaft of the guide roller 156, and the movable guide 170 is rotated counterclockwise in FIG. A biasing means such as a spring for biasing is provided. With such an urging means, the movable guide 170 is urged counterclockwise in FIG. 24 about the shaft 171. By providing such a movable guide 170, the paper sheet sent from the outside of the paper sheet storage and feeding device 140 to the inside of the paper sheet storage and feeding device 140 through the entrance / exit 158 is guided by the guide roller 154. After passing between 156, it is guided by the movable guide 170 so as to be appropriately wound around the drum 142 together with the pair of tapes 150 and 152.

  Further, as shown in FIG. 24, the movable guide 170 is provided with a guide portion 180 facing the pair of tapes 150 and 152. Such a guide unit 180 prevents the folded paper sheets from sandwiching the tapes 150 and 152 from both sides even when the paper sheets are folded when the paper sheets are fed out from the drum 142. It is supposed to be. Here, the guide portion 180 has a position in the axial direction of the drum 142 (that is, a position orthogonal to the paper surface of FIG. 24) facing the pair of tapes 150 and 152 (more precisely, the tape 152). Yes. In FIG. 24, such a guide part 180 is indicated by oblique lines.

  The guide portion 180 has a shape in which both end edges extend along the circumferential direction of the drum 142 so that the width of the drum 142 in the axial direction is constant in the direction in which the paper sheet is fed from the drum 142. . In addition, as another aspect of the shape of the guide part 180, it may have a shape that spreads outward in the width direction of the tapes 150 and 152 as it advances in the direction in which the paper sheet is fed out from the drum 142. The guide unit 180 is disposed so as to protrude toward the drum 142 from the guide surface that guides the paper sheets in the movable guide 170, and the guide unit 180 has a pair of guide surfaces wound around the drum 142. The tapes 150 and 152 face each other so as to come into contact with the surface of the tape 152. In particular, the movable guide 170 to which the guide portion 180 is attached is swingable about the shaft 171 in accordance with the amount of paper stored in the drum 142, and is movable by an urging means such as a spring. Since 170 is pressed in the counterclockwise direction in FIG. 24 about the shaft 171, the guide unit 180 is wound around the drum 142 regardless of whether the amount of paper sheets stored in the drum 142 is large or small. Of the pair of tapes 150 and 152, the surface of the tape 152 comes into contact. Since the guide portion 180 having such a configuration is provided so as to face the pair of tapes 150 and 152, when the pair of tapes 150 and 152 are rewound from the drum 142, the sheet is fed out from the drum 142. Even if the folded portion of the paper sheet tries to get on the surface of each of the tapes 150 and 152, the folded portion of the paper sheet comes into contact with the side surface of the guide portion 180, so that the corresponding portion becomes the tape 150 and 152. This prevents the folded sheets from sandwiching the tapes 150 and 152 from both sides.

  On the other hand, as shown in FIG. 25, such a guide portion 180 is not provided in a conventional paper sheet storage and feeding device 140a as a comparative example. As described above, in the conventional paper sheet storage and feeding device 140 a in which the guide unit 180 is not provided, the pair of tapes 150 and 152 are rewound from the drum 142, whereby the paper sheets are fed from the drum 142. When there is a cut part at the front edge of the paper sheet in the feeding direction of the paper sheet, and the part of the paper sheet is folded by the cut part, the folded part is taped. By contacting the back surface of the tape 150 or the tape 152, folded paper sheets may pinch the tape 150 or the tape 152 from both sides. In such a case, when the paper sheets are discharged from the pair of tapes 150 and 152 in the vicinity of the guide rollers 154 and 156, the portions of the paper sheets that are folded into the tape 150 and the tape 152 are these parts. By being sandwiched between the tapes 150 and 152 and the guide roller 154 or the guide roller 156, there is a possibility that the paper sheets may be torn from the cut portion or the direction may be greatly changed.

  In this way, according to the paper sheet storage and feeding device 140 as shown in FIG. 24, the pair of tapes 150 and 152 are rewound from the drum 142 in the same manner as the temporary storage unit 40 shown in FIGS. Thus, a guide unit 180 is provided for guiding the paper sheet so that the paper sheet is prevented from pinching the tape 150 or the tape 152 from both sides when the paper sheet is fed from the drum 142. By providing such a guide unit 180, even when the paper sheet is folded when the paper sheet is fed out from the drum 142, the folded paper sheet can be attached to both sides of the tape 150 and the tape 152. Since the guide unit 180 prevents the paper sheets from being pinched, the paper sheets are torn near the portion where the paper sheets are discharged from the pair of tapes 150 and 152 (specifically, the guide rollers 154 and 156). It is possible to prevent the direction or the direction from changing greatly.

  Further, as another configuration of the tape-type paper sheet storing and feeding device that stores paper sheets such as banknotes one by one in a rotating body such as a drum and feeds paper sheets one by one from the rotating body. 26 to 28 may be used. Here, FIG. 26 and FIG. 27 are side views showing the configuration of a paper sheet storage and feeding device 240 according to still another modification, and FIG. 28 shows the paper sheet storage and feeding device shown in FIG. 26 and FIG. It is a perspective view which shows the structure of 240. FIG. 26 shows a state when the tape 250 is not wound around the drum 242. FIG. 27 shows a state when all the tape 250 unwound from the tape reel 244 is wound around the drum 242. The state is shown. 29 and 30 are side views showing the configuration of a conventional paper sheet storage and feeding device 240a as a comparative example, and FIG. 31 shows the paper sheet storage and feeding device 240a shown in FIGS. It is a perspective view which shows the structure. 29 shows a state when the tape 250 is not wound around the drum 242. FIG. 30 shows a state when all the tape 250 unwound from the tape reel 244 is wound around the drum 242. The state is shown.

  As shown in FIGS. 26 to 28, the paper sheet storage and feeding device 240 includes a drum 242 that is rotatable, and two strip-shaped tapes 250 each having one end connected to the outer peripheral surface of the drum 242. The other end of each tape 250 has a tape reel 244 connected to the outer peripheral surface thereof. Here, as shown in FIG. 28, the two tapes 250 are arranged along the direction in which the shaft 242a of the drum 242 extends.

  The drum 242 can be rotated about both the clockwise direction and the counterclockwise direction in FIGS. 26 and 27 about the shaft 242a. Specifically, when the paper sheets sent from the outside of the paper sheet storage and feeding device 240 to the inside of the paper sheet storage and feeding device 240 through the entrance / exit 258 are stored in the drum 242, the drum 242 26 and 27 rotate counterclockwise in FIG. 26 and FIG. 27, so that the sheets fed to the vicinity of the drum 242 are wound around the drum 242 together with the tapes 250. On the other hand, when the paper sheets stored in the drum 242 are fed out of the paper sheet storage and feeding device 240, the drum 242 rotates in the clockwise direction in FIG. 26 and FIG. By rewinding the sheet, the paper sheets are released from each of the tapes 250 and sent from the entrance / exit 258 to the outside of the paper sheet storage and feeding device 240.

  As shown in FIGS. 26 and 27, the paper sheet storage and feeding device 240 is provided with guide rollers 252, 254, 256 for guiding each tape 250, and these guide rollers 252, 254, 256 are provided. Thus, each tape 250 is guided between the drum 242 and the tape reel 244. Here, the guide roller 254 and the guide roller 256 are arranged to face each other, and each tape 250 passes between the guide roller 254 and the guide roller 256. In addition, the paper sheet storage / feeding device 240 has a circulation belt 260 for transporting paper sheets fed from the outside to the vicinity of the drum 242 through the entrance / exit 258. The circulation belt 260 is stretched over the pulleys 262, 264, and 266.

  Further, as shown in FIGS. 26 and 27, in the paper sheet storage and feeding device 240, the drum 242 has a first peripheral portion (specifically, on the left side of the drum 242 in FIGS. 26 and 27). A movable guide 270 is provided. The first movable guide 270 rotates about a shaft 271 provided coaxially with the shaft of the pulley 266 around which the circulation belt 260 is stretched, and the first movable guide 270 is centered on the shaft 271. Biasing means such as a spring for biasing 270 in the counterclockwise direction in FIGS. 26 and 27 is provided. Further, the first movable guide 270 is provided with a plurality of bearings 274 that press the paper sheets wound around the drum 242 toward the shaft 242a side of the drum 242 (see FIGS. 26 to 28). The first movable guide 270 is biased about the shaft 271 in the counterclockwise direction in FIGS. 26 and 27 by the biasing means such as a spring, whereby each bearing 274 is moved in the right direction in FIGS. 26 and 27. Thus, the paper sheets wound around the drum 242 are pressed toward the shaft 242a side of the drum 242 by the bearings 274. Further, since the first movable guide 270 is urged in the counterclockwise direction in FIGS. 26 and 27 by the urging means such as a spring around the shaft 271, the first movable guide 270 is wound around the drum 242. Even if the outer diameter of each tape 250 is reduced by rewinding the paper sheets from the drum 242, the bearings 274 always come into contact with the paper sheets and press the paper sheets.

  As shown in FIGS. 26 and 27, in the paper sheet storage and feeding device 240, the second movable guide 272 is disposed above the drum 242 so as to face the first movable guide 270 with a slight gap therebetween. A guide roller 254 is provided at the tip of the second movable guide 272. The second movable guide 272 is fixed to the first movable guide 270, and rotates around the shaft 271 in synchronization with the first movable guide 270. Here, the paper sheet sent from the outside of the paper sheet storage and feeding device 240 to the inside of the paper sheet storage and feeding device 240 via the entrance / exit 258 is placed between the circulation belt 260 and the second movable guide 272. Guided through the gap, and then guided through the gap between the first movable guide 270 and the second movable guide 272. Then, after the paper sheets are guided through the gap between the first movable guide 270 and the second movable guide 272, the paper sheets are wound around the drum 242 by each tape 250. Further, the guide roller 256 provided on the first movable guide 270 and the guide roller 254 provided on the second movable guide 272 are pressed against each other toward the other guide roller. The paper sheets to be sent to the drum 242 through the gap between the second movable guide 272 and the paper sheets rewound from the drum 242 are nip portions formed between the guide rollers 254 and 256. Is supposed to pass through.

  In the paper sheet storage and feeding device 240 shown in FIGS. 26 to 28, the paper sheet is folded when the drum 242 rotates in the clockwise direction in FIGS. 26 and 27 and the paper sheet is fed from the drum 242. Even when the paper sheet is folded, a guide portion 280 is provided to prevent the folded paper sheets from sandwiching the tape 250 from both sides. Here, as shown in FIG. 28, two tapes 250 are provided so as to be aligned along the axial direction of the drum 242, and two guide portions 280 are provided corresponding to each tape 250. More specifically, as shown in FIG. 28, each guide portion 280 has a position in the axial direction of the drum 242 (that is, a position in the left-right direction in FIG. 28) facing each tape 250. In FIG. 26 and FIG. 27, such a guide portion 280 is indicated by hatching.

  As shown in FIG. 28, each guide portion 280 has a constant width in the axial direction of the drum 242 (that is, a width in the left-right direction in FIG. 28) in the direction in which the sheets are fed out from the drum 242. Both end edges thereof have a shape extending along the circumferential direction of the drum 242. Each guide portion 280 is disposed so as to protrude from the guide surface 270a for guiding the paper sheets in the first movable guide 270 toward the drum 242 side, and the guide surface 280a of each guide portion 280 These tapes 250 are opposed to each other with a slight gap from the surface of each tape 250 wound around 242. In particular, the first movable guide 270 to which each guide portion 280 is attached is swingable about the shaft 271 according to the amount of paper sheets stored in the drum 242, and this first movable guide 270. The first movable guide 270 is rotated counterclockwise in FIGS. 26 and 27 by the biasing means such as a spring so that the bearings 274 provided on the drum 242 come into contact with the paper sheets wound around the drum 242. Since the sheet is pressed in the direction, the amount of paper sheets stored in the drum 242 is large or small, so that the space between the guide surface 280a of each guide portion 280 and the surface of each tape 250 wound around the drum 242 can be reduced. A slight gap is formed. Since each guide portion 280 having such a structure is provided so as to face each tape 250 and form a slight gap between these tapes 250, each tape 250 is rewound from the drum 242. When the paper sheet is fed out of the drum 242 by the above, even if the folded part of the paper sheet tries to get on the surface of each tape 250, the folded part of the paper sheet contacts the side surface of the guide portion 280. This suppresses the portion from getting on the surface of each tape 250, which prevents the folded paper sheets from sandwiching the tape 250 from both sides.

  On the other hand, as shown in FIGS. 29 to 31, such a guide 280 is not provided in the conventional paper sheet storage and feeding device 240a as a comparative example. As described above, in the conventional paper sheet storage and feeding device 240a in which the guide unit 280 is not provided, when the tapes 250 are rewound from the drum 242, the paper sheets are fed from the drum 242. When there is a cut portion at the front edge of the paper sheet in the feeding direction of the paper sheet and a part of the paper sheet is folded by the cut portion, the folded portion is By contacting the back surface, folded paper sheets may pinch each tape 250 from both sides. In such a case, when the paper sheet is discharged from each tape 250 in the vicinity of the guide roller 252, the portion of the paper sheet that is folded into the tape 250 is between the tape 250 and the guide roller 252. By being pinched, there is a possibility that the paper sheets may be torn from the cut portion or the direction may be greatly changed.

  As described above, according to the paper sheet storage and feeding device 240 as shown in FIGS. 26 to 28, each tape 250 is rewound from the drum 242 in the same manner as the temporary storage unit 40 shown in FIGS. Thus, a guide 280 for guiding the paper sheets is provided so as to prevent the paper sheets from pinching the tapes 250 from both sides when the paper sheets are fed from the drum 242. By providing such a guide portion 280, even when a paper sheet is folded when the paper sheet is fed out from the drum 242, the folded paper sheet sandwiches each tape 250 from both sides. Since the guide unit 280 prevents the paper sheet from being released, the paper sheet is torn near the location where the paper sheet is discharged from each tape 250 (specifically, the guide roller 252) or the direction is greatly changed. Can be suppressed.
