In the upper right of FIG. 3, XYZ coordinates representing the direction of illustration with respect to FIG. 1 and the like are shown. Moreover, ST coordinate is a coordinate on the basis of the moving direction of a banknote, S direction is a direction parallel to a banknote moving direction, and T direction is a direction orthogonal to S direction. 7 to 12 are shown by ST coordinates. In addition, since FIGS. 4-6 is the same illustration direction as FIG. 3, the display of a coordinate is abbreviate | omitted below.

  First, with reference to FIG. 3, the structure of the banknote depositing / withdrawing apparatus 10 is demonstrated. The banknote deposit / withdrawal apparatus 10 includes a storage unit 50, a feeding unit 70, a return unit 80, and a foreign matter discharge unit 90.

  The storage unit 50 is provided inside the banknote deposit / withdrawal port 154 and collectively stores the banknotes 400 inserted in the Q1 direction from customers. The storage unit 50 is provided with a stage 52 and a roof 54 as a pair of moving members that move the banknote 400 between the front and rear. A stage 52 is provided on the front side of the storage unit 50, and a roof 54 is provided on the rear side of the storage unit 50. The stage 52 and the roof 54 sandwich the banknote 400, and move the banknote 400 from the storage unit 50 to the feeding unit 70 in the sandwiched state. The stage 52 and the roof 54 are members that are long in the width direction and are erected in an obliquely upward direction. The stage 52 and the roof 54 are moved between the storage unit 50 and the feeding unit 70 by driving means (not shown). The roof 54 sandwiches the paper sheet from the side closer to the feeding part 70 of the pair of moving members, and the stage 52 sandwiches the paper sheet from the side farther from the feeding part 70 of the pair of moving members. The roof 54 is also called a first moving member, and the stage 52 is also called a second moving member.

  A bottom plate 56 that supports the inserted bill 400 is provided below the storage unit 50. An elongated bar for supporting the banknote 400 is provided on the bottom plate 56 in the front-rear direction. The bars are provided at regular intervals along the width direction. There is a large gap between the bars so that the foreign matter thrown in the bill 400 is dropped down.

  A bridge 58 is provided on substantially the same plane as the bottom plate 56. The bridge 58 is also called a pedestal. Similarly to the bottom plate 56, the bridge 58 is provided with an elongated arm for supporting the banknote in the front-rear direction. The arms are provided at regular intervals along the width direction. A large gap is formed between the arms so that the foreign matter thrown in the bill 400 is dropped down.

  The bridge 58 is movable along the movement direction (S direction) of the banknote 400, and moves between a position covering the foreign matter discharge unit 90 and a position covering the return unit 80. In FIG. 3, the bridge 58 is in a position covering the foreign matter discharge portion 90. In addition, when the arm of the bridge 58 is set so as to be slightly above the bar of the bottom plate 56 and the bridge 58 is in a position covering the foreign matter discharge portion 90, that is, the position where the bridge 58 overlaps the bottom plate 56. The arm of the bridge 58 contacts the bottom surface of the bill 400.

  The feeding unit 70 conveys the banknote 400 moved from the storage unit 50 to the transport path 32 connected to the banknote depositing / dispensing apparatus 10. The feeding unit 70 includes a feeding roller 72 and an impeller 74. The feeding roller 72 is a roller for pulling out banknotes 400 bundled by the feeding unit 70 one by one. The impeller 74 is for feeding the banknotes 400 one by one drawn by the feeding roller 72 to the transport path 32. A plurality of gaps for allowing the feeding roller 72 to pass therethrough are formed on the surface of the roof 54 sandwiching the banknote 400 so that the feeding roller 72 contacts the banknote 400.

  A fork 60 is provided below the roof 54. The fork 60 is disposed in a direction substantially parallel to the roof 54. The fork 60 is for closing (filling) a gap for passing the feeding roller 72 formed in the roof 54. The fork 60 is also called a shielding member. The fork 60 is a member for narrowing the gap between the storage unit 50 and the feeding unit 70 to such an extent that foreign matter does not enter the feeding unit 70. The fork 60 is movable up and down (T direction). FIG. 3 shows a state in which the fork 60 is raised. In the state where the bill 400 is inserted into the storage unit 50, the fork 60 is raised to narrow the gap between the roofs 54.

  The return unit 80 holds the deposited banknote, returns the banknote 400 from the upper opening to the storage unit 50 by the push-up stand 82 provided at the lower part, and returns it to the customer. The impeller 84 moves the banknote 400 to the push-up stand 82 one by one.

  The foreign matter discharge unit 90 is provided at the lower portion of the storage unit 50 and returns the foreign matter 500 mixed in the banknote 400 to a return port (not shown) provided in the automatic transaction apparatus 1. The foreign object 500a thrown into the storage unit 50 passes through the gap formed in the bottom plate 56 and the bridge 58, and falls to the foreign object discharge part 90 as the foreign object 500b. The foreign material 500b that has entered the foreign material discharge section 90 is returned to the return port through a passage (not shown).

  If the foreign object 500a thrown into the storage unit 50 advances in the direction of hitting the rear roof 54, there is a possibility that the foreign object 500a may enter the feeding unit 70 through the gap of the roof 54 if there is no fork 60 as in the prior art. was there. However, in the present embodiment, since the fork 60 that eliminates or narrows the gap of the roof 54 is provided, the foreign object 500a is bounced back by the roof 54 or the fork 60 and falls as the foreign object 500b in the foreign object discharge portion 90. To do. Thus, by providing the fork 60, it is possible to reliably prevent the foreign matter 500a from entering the feeding portion 70 through the gap of the roof 54.

  FIG. 4 is a diagram illustrating the fall of the foreign object 500 due to the vibration of the bridge 58. In addition to the configuration of FIG. 3 or by itself, the fall of the foreign material 500 can be promoted by vibrating the bridge 58 in the movement direction of the banknote 400.

  The banknote 400 is inserted into the storage unit 50, and the bridge 58 is vibrated for a predetermined time (or a predetermined number of times) along the Q2 direction (the banknote movement direction) before the inserted banknote 400 is sandwiched between the stage 52 and the roof 54. Thereby, for example, even in the case of the foreign matter 500c that has entered the space between the banknotes 400 stored obliquely and has become difficult to be discharged, the foreign matter 500c can be easily removed from the banknotes 400 by vibrating the entire banknote 400.

  The foreign object 500c that has fallen out of the banknote 400 falls into the foreign object discharge unit 90 as a foreign object 500d. Note that the vibration of the bridge 58 may be started at the same time as the stage 52 and the roof 54 are sandwiched or after the sandwiching, and may be before the banknote 400 moves to the feeding unit 70.

  FIG. 5 is a diagram illustrating a state where the inserted banknote 400 is moved from the storage unit 50 to the feeding unit 70. First, the stage 52 moves to the rear side, the inserted banknote 400 is applied to the roof 54, and the banknote 400 is pinched. Thereafter, the stage 52 and the roof 54 sandwiching the banknote 400 move to the feeding unit 70.

  When the banknote 400 is moved from the storage unit 50 to the feeding unit 70, the fork 60 descends in the Q3 direction and retracts from the movement path of the banknote 400. Further, the bridge 58 moves from the position covering the foreign matter discharge section 90 to the position where it proceeds to the rear side (Q4 direction) and covers the upper opening of the return section 80. The reason why the bridge 58 is moved onto the return unit 80 is to support the banknote passing over the return unit 80. The timing of lowering the fork 60 and moving the bridge 58 may be any time when the stage 52 starts to move backward, or when the stage 52 sandwiching the banknote 400 starts moving to the feeding portion 70 of the roof 54. .

  FIG. 6 is a diagram illustrating a state where the inserted banknote 400 has been moved to the feeding unit 70. The banknote 400 sandwiched between the stage 52 and the roof 54 passes over the bridge 58 moved onto the return unit 80 and moves to the feeding unit 70. The feeding roller 72 protrudes from the gap formed in the roof 54 and comes into contact with the banknote 400. Thereafter, the feeding roller 72 and the impeller 74 are driven, and the banknotes 400 are conveyed out of the banknote depositing / dispensing apparatus 10 one by one.

  FIG. 7 is a three-side view of the banknote depositing / dispensing device 10 and is a diagram in which parts related to the roof 54 and the fork 60 are extracted. 7A is a view in the same direction as FIG. 3, FIG. 7B is a view seen from the T direction in FIG. 3 (hereinafter also referred to as a top view), and FIG. 7C is a view in FIG.

In the vicinity of the drive motor 100, a transmission gear A102 composed of a plurality of gears is provided in order to reduce and transmit the driving force.

  The rotating shaft 104 is coupled to the output portion of the transmission gear A102. The rotating shaft 104 is provided with a length that extends from the right end to the left end so as to penetrate under the bottom plate 56. A manual knob 110 for manually driving is provided at the left end of the rotating shaft 104.

  In addition, transmission gears B106 are provided on the left and right of the rotating shaft 104, respectively. The transmission gear B106 is a combination of a plurality of gears, and transmits the rotation of the rotating shaft 104 to the bridge 58. The left and right transmission gears B106 mesh with the left and right racks 58c of the bridge 58 (see FIG. 7A). Further, the two bridge rollers 58d provided at the left and right ends of the bridge 58 are fitted into guide grooves (not shown) provided at the left and right correspondingly. Thereby, the bridge 58 is guided to move in the front-rear direction. With such a configuration, the bridge 58 moves in the front-rear direction according to the rotation of the drive motor 100.

  In addition, cam rollers 108 are provided inside the left and right transmission gears B106 of the rotating shaft 104, respectively. The cam roller 108 is a cam for moving the fork 60 up and down. The vertical movement of the fork 60 will be described with reference to FIGS.

  FIG. 7C is a view for explaining the shapes of the roof 54 and the fork 60. The stage 52 is omitted. FIG. 9 is an exploded view in which the main members of FIG. FIG. 9A is the same as FIG. 7C. FIG. 9B is a front view of the roof 54. FIG. 9C is a front view of the fork 60. FIG. 9D is a front view of the bridge 58.

  As shown in FIG. 9B, the roof 54 has a base 54 a at a portion in contact with the banknote 400. The base 54a is provided with a plurality of gaps e for allowing the feeding roller 72 to enter from the back surface, and the base 54a is formed in a comb shape when viewed from the front surface.

  As shown in FIG. 9C, the fork 60 has a base 60a that is long in the width direction. A plurality of segments 60b extending upward are provided on the upper portion of the base 60a. The section 60b is for closing (filling) the gap e of the roof 54, and the shape of the section 60b is a shape corresponding to the gap e. That is, the upper portion of the fork 60 is also formed in a comb-tooth shape that fills the gap e of the roof 54.

  At the left and right ends of the fork 60, a pair of cam pins 60c for moving the fork 60 up and down is provided. Two fork rollers 60d for guiding the vertical movement of the fork 60 are provided at the left and right ends of the fork 60, respectively (see FIGS. 7A and 10). The base 60 a is engaged with a hook (not shown) of the spring 62 at the center, and the fork 60 is constantly urged downward by the spring 62. Regarding the drive mechanism of the fork 60, the fork 60 moves up and down by a drive mechanism described later in FIGS. 10 to 12. However, in the retracted state shown in FIG. 5, the fork 60 moves the entire section 60 b of the banknote 400. Go down to a position below the path.

  As shown in FIG. 9D, the bridge 58 is a flat member. As described above, the racks 58c are provided at the bottoms of the left and right ends of the bridge 58, and the bridge rollers 58d are provided on the side surfaces of the left and right ends of the bridge 58 (see FIGS. 7A and 10).

  FIG. 10 is a diagram for explaining a drive mechanism for the bridge 58 and the fork 60. FIG. 10A is an enlarged view of a portion of the drive mechanism of FIG. FIG. 10B is an enlarged view of the left side of FIG. As described above, FIG. 10 is a diagram illustrating a state in which the bill 400 is inserted, and the bridge 58 is in a position covering the foreign matter discharging unit 90 and the fork 60 is in a raised position.

  Racks 58 c provided at the left and right ends of the bridge 58 mesh with a transmission gear B 106 provided on the rotating shaft 104. As described above, the bridge 58 is guided in the front-rear direction by the bridge roller 58d being incorporated in a guide groove (not shown). When the rotation shaft 104 is rotated CCW (counterclockwise) by the drive motor 100 from the state of FIG. 10, the bridge 58 moves backward, that is, to a position covering the return unit 80.

  Further, two upper and lower fork rollers 60d are fitted in a guide groove (not shown), and the fork 60 is guided to move in the vertical direction by the guide groove. Then, a pair of cam pins 60 c provided at the left and right ends of the fork 60 abut on the outer periphery of the cylindrical surface of the corresponding cam roller 108. This is because the fork 60 is biased downward by the spring 62.

  FIG. 11 is a view for explaining the cam shape of the cam roller 108. It is the figure which looked at the cam roller 108 from the reverse direction to FIG. With the cam roller 108, a fan-shaped range with a constant angle (in this example, about 120 °) is cut out with a width of about half of the whole, and the cut-out portion forms a cam portion 108a. The boundary of the cam portion 108a is indicated by r so that the angular position of the cam roller 108 can be easily understood.

  FIG. 12 is a diagram for explaining how the cam pin 60c moves up and down in accordance with the rotation angle of the cam roller. FIG. 12 is a view as seen from the same direction as FIG. FIG. 12A shows the same state as FIG.

  Corresponding to the CCW (counterclockwise) rotation of the rotating shaft 104, the cam roller 108 also rotates counterclockwise. FIG. 12B shows a state in which the boundary r of the cam roller 108 is positioned immediately before the cam pin 60c. The position of the cam pin 60c does not change between FIG. 12 (A) and FIG. 12 (B). 4 is performed within this range, the height position of the fork 60 is not changed.

  FIG. 12C shows a state where the cam roller 108 is further rotated counterclockwise. Since the fork 60 is biased downward, the cam pin 60c enters the cam portion 108a and is lowered, and the fork 60 is lowered to a position where the cam pin 60c contacts the cam portion 108a.

  FIG. 12D shows a state in which the cam roller 108 further rotates counterclockwise and the cam pin 60c is lowered to the lower limit. The state of FIG. 12D is a state where the drive motor 100 is stopped and the fork 60 is completely retracted from the movement path of the banknote 400. A stopper (not shown) for defining a lower limit position of the fork 60 is provided, and the fork 60 stops descending at a position defined by a stopper (not shown). In addition, in the state of FIG. 12D, the bridge 58 is completely moved to a position that covers the return unit 80.

  Then, the banknote 400 is moved to the feeding part 70, and a banknote is conveyed inside. After the conveyance of the banknote 400 is completed, the drive motor 100 is rotated in the clockwise direction. By rotation of the cam roller 108, the cam pin 60c is pushed up by the cam portion 108a, and the fork 60 moves up to the position shown in FIG. The bridge 58 also moves from a position covering the return unit 80 to a position covering the foreign matter discharge unit 90 shown in FIG. A series of control processes including movement by the stage 52 and the roof 54 and detection of various sensors are executed by the central processing unit.

  According to the embodiment described above, since the fork 60 is provided as a shielding member that closes the gap between the roofs, it is possible to reliably prevent foreign matter from entering from the gap of the roof 54 toward the feeding portion. Further, since the fork 60 moves away from the banknote movement path, there is no possibility of hindering movement of the banknote. In addition, since the inserted banknote is shaken before moving to the feeding unit 70, the foreign object falls between the banknotes even when the foreign object or the banknote inserted between the banknotes is inserted obliquely. Can be made.

  Further, as an example of the fork 60, a comb-like member corresponding to the uneven shape of the roof 54 has been described. However, the present invention is not limited to this, and for example, a thin plate without a gap is used to form the roof 54 from the back surface of the roof 54. The entire gap may be closed. In addition, the reciprocating movement of the bridge 58 and the installation of the fork 60 may be performed independently, and in any case, a foreign matter removing effect can be achieved.

  Note that the present invention is not limited to the above-described embodiments as they are, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. Moreover, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, all the constituent elements shown in the embodiments may be appropriately combined. Furthermore, constituent elements over different embodiments may be appropriately combined. It goes without saying that various modifications and applications are possible without departing from the spirit of the invention.
