  First, before specifically describing the embodiment of the present invention, the basic configuration of the banknote handling unit according to the embodiment of the present invention will be described with reference to FIGS. 3A and 3B. FIG. 3A is a schematic side view showing the basic configuration of the banknote handling unit according to the embodiment of the present invention. FIG. 3B is a schematic front view illustrating the basic configuration of the banknote handling unit illustrated in FIG. 3A.

  The banknote processing unit 10 illustrated in FIGS. 3A and 3B is a paper sheet handling apparatus that takes out banknotes 12 stored in the banknote storage 11. The banknote processing unit 10 includes a banknote storage 11 that is a storage for storing banknotes 12 in a stacked manner, and is provided on one side of the banknote storage 11 to carry out the banknotes 12. Is formed.

  The banknote processing unit 10 further includes a stage 13 that moves the banknotes 12 stacked in the banknote storage 11 in the stacking direction of the banknotes 12 (arrow A (vertical direction)), and a banknote pressed against the roller surface by the stage 13. Pick roller 14 that is a transport roller for transporting 12 to carry-out port 16, feed roller 15 that feeds banknotes 12 transported to carry-out port 16 by pick roller 14 from carry-out port 16, and banknotes 12 to carry-out port 16. Guide member 17 for assisting the conveyance of the banknote 12 and detection means 20 for detecting the folding or bending of the banknote 12 that prevents the banknote 12 from being carried out of the banknote storage 11.

  The banknote processing unit 10 is a banknote processing unit according to the related art exemplified in FIGS. 2A and 2B in that the point including the detection unit 20 and the operation of the pick roller 14 is limited by the detection result of the detection unit 20. It is different from 100.

  The detection means 20 is a means for detecting the folding or bending of the banknote 12 that prevents the banknote 12 from being carried out of the banknote storage 11, but more specifically, the conveyance direction of the banknote 12 by the pick roller 14 (arrow B). , The state in which at least a part of the banknote 12 stacked on the side of the pick roller 14 in the banknote storage 11 is higher than the carry-out port 16, that is, the rotation of the pick roller 14 from the carry-out port 16. It is configured to detect a state (hereinafter referred to as a defective state) located on the shaft 14a side.

  Detection of a defective state is performed by the detection means 20, for example, a lever member 18 that moves by contact with the banknote 12 that is stacked most on the side of the pick roller 14 in the banknote storage 11, and a predetermined amount of the lever member 18 by the contact. This is realized by including the sensor 19 that detects the above movement.

  Basically, in the pick roller 14, as in the pick roller 104 illustrated in FIGS. 2A and 2B, the bill 12 is pressed against the roller surface by the movement of the stage 13, and a certain load is applied to the pick roller 14. Sometimes rotate. However, the pick roller 14 is configured to stop the conveyance of the banknote 12 even if a constant load is applied to the pick roller 14 when the detecting means 20 detects a defective state. This is different from the pick roller 104.

  Note that the pick roller 14 is designed so that the height of the lower surface of the pick roller 14 is within the height range in which the carry-out port 16 is formed during rotation, as illustrated in FIGS. 2A and 2B. The same as the pick roller 104 of the bill processing unit 100 to be performed.

  According to the banknote processing unit 10, the banknote 12 conveyed by the pick roller 14 is caught at the entrance of the carry-out port 16 by detecting a defective state and stopping the conveyance of the banknote 12 by the pick roller 14. It is possible to prevent a situation in which the conveyance posture of the banknote 12 changes due to contact (friction) with the entrance of the carry-out port 16 or the guide member 17. Thereby, since generation | occurrence | production of a paper jam (jam) can be suppressed and it becomes possible to operate the banknote processing unit 10 normally, stability of feeding of the banknote 12 can be improved.

  3A and 3B show an example in which the guide member 17 is provided at a position higher than the carry-out port 16, that is, on the rotation shaft 14a side of the pick roller 14 from the carry-out port 16. The positional relationship between the member 17 and the carry-out port 16 is not limited to this. The guide member 17 may be provided within the height range of the carry-out port 16 as long as the guide member 17 is provided closer to the rotary shaft 14a than the lower surface of the pick roller 14 during rotation.

  However, in consideration of the case where the guide member 17 is provided within the height range of the carry-out port 16, the detection unit 20 includes at least one of the paper sheets stacked on the pick roller 14 side in the banknote storage 11. As seen from the conveyance direction of the bill 12 by the pick roller 14, the part is located closer to the rotary shaft 14 a side of the pick roller 14 than one of the carry-out port 16 or the guide member 17 near the stage 13. It is desirable to be configured.

  Examples of the present invention will be specifically described below.

  FIG. 4A is a top view of the banknote handling unit according to the present embodiment. 4B and 4C are side views of the banknote processing unit illustrated in FIG. 4A, and are views when viewed from the directions of arrows C and D shown in FIG. 4A, respectively. FIG. 5 is a diagram for explaining a relationship between a lever member and a photo interrupter included in the banknote processing unit illustrated in FIG. 4A.

  As illustrated in FIG. 4C, the banknote handling unit 30 according to the present embodiment includes a banknote storage 31 that is a storage for stacking and storing banknotes 32, and the banknotes 32 are carried out to one side surface thereof. A provided outlet 36 is formed. The carry-out port 36 has an opening width through which a plurality of bills 32 (for example, about 10) can pass, but to the carry-out port 36 for bills other than bills that are in contact with the pick roller 34 by the separator 41. Is prevented from entering.

  Although not shown, the banknote processing unit 30 includes a stage on which the banknotes 32 stacked in the banknote storage 31 are placed and moved in the stacking direction of the banknotes 32. The stage is driven by a motor or the like (not shown).

  As illustrated in FIG. 4A, the banknote handling unit 30 includes four pick rollers 34 that transport the banknote 32 pressed against the roller surface by the movement of the stage to the carry-out port 36, and the banknote 32 transported by the pick roller 34. Are provided with three feed rollers 35 for feeding the toner from the carry-out port 36 to the outside, and four metal rollers 42 sharing the rotation shaft 35a with the feed roller 35.

  The pick roller 34 and the feed roller 35 are drive rollers that are driven by the rotation of the rotation shaft 34a and the rotation shaft 35a, respectively, whereas the metal roller 42 is rotatably attached to the rotation shaft 35a. It is a driven roller. The pick roller 34 rotates when a constant load is applied, but is configured to stop regardless of the applied load when a detection means 40 described later detects a defective state.

  Moreover, as illustrated in FIG. 4A, the pick roller 34 and the feed roller 35 are disposed in an area in the banknote storage 31 that is relatively close to the center in the rotation axis direction. On the other hand, like the pick roller 34 and the feed roller 35, two of the four metal rollers 42 are disposed in a region relatively close to the center in the rotation axis direction, while the remaining two are on the outer side. Is located in the area. Thus, by arranging a plurality of metal rollers 42 that are driven rollers over a relatively wide range, the stability of the conveying posture of the banknote 32 can be improved.

Furthermore, as illustrated in FIG. 4C, the pick roller 34 is designed such that the height of the lower surface of the pick roller 34 is within the height range of the carry-out port 36 during rotation.
As illustrated in FIGS. 4A and 4C, the banknote processing unit 30 is stacked on the side closest to the pick roller 34 in the banknote storage 31 and the guide member 37 that assists the conveyance of the banknote 32 to the carry-out port 36. There are provided four lever members 38 that rotate around the rotation axis 38 a by contact with the banknote 32, and three photo interrupters 39 that are optical sensors that detect changes in the amount of incident light due to the movement of the lever member 38. The lever member 38 and the photo interrupter 39 function as detection means 40 that detects a defective state.

  As illustrated in FIG. 4C, the guide member 37 is provided at a position higher than the carry-out port 36, that is, closer to the rotation shaft 34 a of the pick roller 34 than the carry-out port 36 when viewed from the conveyance direction by the pick roller 34. Yes. The lever member 38 is supported by the rotating shaft 38 a in a state of protruding from the gap of the guide member 37 toward the stage (not shown) from the guide member 37. Although not shown, the photo interrupter 39 has a light emitting element and a light receiving element facing each other. In place of the photo interrupter 39, another optical sensor such as a photo reflector may be used.

Hereinafter, with reference to FIG. 5, how the relationship between the lever member and the photo interrupter changes according to the change in the position of the banknote 32 will be specifically described.
First, when the banknote 32 on the most pick roller side is, for example, at the position indicated by the dotted line in FIG. 5 and the banknote 32 is not in contact with the lever member 38, the lever member protrudes to the stage side from the guide member 37. The portion 38 (hereinafter referred to as a protruding portion) is at a relatively low position. In this state, the end of the lever member 38 on the opposite side of the protruding portion with respect to the rotation shaft 38 a (hereinafter referred to as a blocking portion) straddles the optical axis 39 a of the photo interrupter 39. For this reason, the light emitted from the light emitting portion of the photo interrupter 39 is blocked by the blocking portion of the lever member 38 and is not detected by the light receiving portion of the photo interrupter 39.

  When the bill 32 comes into contact with the lever member 38 and the protruding portion of the lever member 38 is pushed up, the lever member 38 rotates clockwise around the rotation shaft 38a, and the blocking portion of the lever member 38 is lowered. Moving. When the bill 32 moves to the position indicated by the solid line in FIG. 5 and the protruding portion of the lever member 38 is pushed up by a predetermined amount or more, the blocking portion of the lever member 38 comes off from the optical axis 39a of the photo interrupter 39. Move to the desired position. In this state, the light emitted from the light emitting unit of the photo interrupter 39 reaches the light receiving unit and is detected by the light receiving unit.

  Thus, the photo interrupter 39 can detect whether or not the lever member 38 has moved a predetermined amount or more by detecting whether or not light is detected, that is, by detecting a change in the amount of incident light.

  That is, when the photo interrupter 39 detects light, the bill state is determined to be defective and the pick roller 34 stops rotating. When the photo interrupter 39 does not detect light, the bill state is determined to be good and the pip roller 34 rotates. Will be driven.

  In the banknote handling unit 30, the predetermined amount and the movement amount by which the lever member 38 moves from when the banknote 32 contacts the lever member 38 to when the banknote 32 exceeds the height range of the carry-out port 36 are made to coincide with each other. In addition, the positional relationship between the lever member 38 and the photo interrupter 39 is adjusted in advance.

  Thereby, the detection means 40 is a defect state, ie, at least one part of the banknote 32 laminated | stacked most on the pick roller side in the banknote storage 31 is seen from the conveyance direction of the banknote 32 by a pick roller from the carry-out port 36. Also, the state of the pick roller 34 positioned on the rotating shaft 34a side can be detected.

  According to the banknote processing unit 30 configured as described above, the banknote 32 conveyed by the pick roller 34 is moved to the entrance of the carry-out port 36 by detecting a defective state and stopping the conveyance of the banknote 32 by the pick roller 34. It is possible to prevent the situation where the banknote 32 is conveyed and the situation where the banknote 32 is conveyed due to contact (friction) with the entrance of the carry-out port 36 and the guide member 37 (friction) can be prevented. Thereby, since generation | occurrence | production of a paper jam (jam) can be suppressed and it becomes possible to operate the banknote processing unit 30 normally, stability of feeding of the banknote 32 can be improved.

  In the present embodiment, the configuration in which the four lever members 38 are provided is illustrated, but the number of the lever members 38 is not limited to four, and at least one may be sufficient. However, by providing more, it becomes possible to more reliably detect the folding or bending of the banknote that prevents stable feeding of the banknote. In the banknote handling unit 30 according to the present embodiment, both end portions and the central portion that are considered to be positioned higher than the carry-out port 36 when the banknotes are folded in a commonly seen folding manner (for example, four-fold or three-fold). Two lever members 38 are arranged in each of the two. Thereby, it is possible to detect a defective state more reliably with a small number of lever members 38.

  Moreover, in the banknote processing unit 30 according to the present embodiment, the two lever members 38 that are close to the center of the four lever members 38 are connected to each other, and are configured such that the other rotates in response to one rotation. ing. Such a configuration is desirable in that the number of photointerrupters 39 per lever member 38 can be reduced as illustrated in FIG. 4A, which contributes to a reduction in the number of parts and a reduction in the size of the apparatus.
