A pinch roller 33 and a roller 35 are disposed opposite to each other in the conveyance path 15g of the medium recovery device 5. A sensor 27 that detects the passage of the medium is provided in the transport path 15d. The sensor 27 is, for example, a photo sensor. A pinch roller 31 and a roller 29 are arranged opposite to each other at the boundary between the conveyance path 15d and the conveyance path 15e. In addition, a gate 37 is provided on the pinch roller 31 and the roller 29 further on the collection unit 43 side.

  The roller 21 and the pinch roller 23 convey the medium conveyed through the conveyance path 15a or the conveyance path 15c in a state where the medium is sandwiched between them, thereby conveying the medium to the medium recovery device 5 side or the inside of the front stage 3. . For example, the roller 21 is fixed to the medium recovery device 5 via the shaft 21a, and rotates by being applied with a driving force in accordance with the direction in which the medium is conveyed. The pinch roller 23 is configured to be pressed against the roller 21 and to be appropriately moved as the medium passes. The rotation direction of the roller 21 and the pinch roller 23 is variable according to the direction in which the medium is conveyed.

  The gate 25 rotates around the shaft 25a as shown by an arrow 25b by turning on and off the magnet A (not shown), and switches the conveyance path connected to the conveyance path 15c between the conveyance path 15d and the conveyance path 15g. When the transport path 15c and the transport path 15g are connected, the transported medium is turned upside down and returned to the transport path 15c. By connecting the conveyance path 15c and the conveyance path 15d, the medium conveyed from the conveyance path 15c is conveyed to the conveyance path 15d side, and the medium conveyed from the conveyance path 15d side is conveyed to the conveyance path 15c side. You can do it. The sensor 27 is a photo sensor, for example, and detects whether or not the medium has passed.

  The pinch roller 33 and the roller 35 convey the medium conveyed through the conveyance path 15g to the top and bottom turn part 17 side or the front stage part 3 inner side by rotating in a state of being sandwiched between them. For example, the roller 35 is fixed to the medium recovery device 5 via the shaft 35a, and is rotated by applying a driving force in accordance with the direction in which the medium is conveyed. The pinch roller 33 is configured to be pressed against the roller 35 and to be appropriately moved as the medium passes.

  The roller 29 and the pinch roller 31 rotate in a state where the medium conveyed through the conveyance path 15d is sandwiched between them, so that the side of the conveyance path 15e or the inside of the collection unit 43 depends on the rotation state of the gate 37. To the side. For example, the roller 29 is fixed to the medium recovery device 5 via the shaft 29a, and is rotated by applying a driving force in accordance with the direction in which the medium is conveyed. The pinch roller 31 is configured to be pressed against the roller 29 and to be appropriately moved as the medium passes. The rotation directions of the roller 29 and the pinch roller 31 are variable according to the direction in which the medium is conveyed. Details of the configuration of the pinch roller 31 will be described later.

  The gate 37 includes a pressing portion 38 and a shielding portion 39, and rotates as shown by an arrow 37b about the shaft 37a by turning on and off a magnet B (not shown). The gate 37 switches the connection between the conveyance path 15 d and the conveyance path 15 e or the collection unit 43 and presses the medium against the pinch roller 31 when the medium passes between the pinch roller 31 and the roller 29. When the medium is completely stored in the collection unit 43, the conveyance path 15d and the conveyance path 15e are connected by the gate 37. At this time, the shielding unit 39 enters the sensor 41 and blocks light. The sensor 41 is, for example, a photo sensor. The control unit 8 detects that the medium is completely stored in the recovery unit 43 by detecting that the gate 37 is completely rotated to the side connecting the conveyance path 15d to the conveyance path 15e by the sensor 41. To do. Details of the configuration of the gate 37 will be described later.

  3A and 3B are diagrams showing the configuration of the pinch roller 31, wherein FIG. 3A is a schematic view of a contact surface, and FIG. 3B is a side view. As shown in FIG. 3, when the contact surface with the medium is viewed, the pinch roller 31 is formed with a convex portion 31a sandwiching a notch portion 31b on the right side of the drawing in the example of FIG. As shown in FIG. 3B, when viewed from the side, the pinch roller 31 has an outer periphery that is slightly larger (diameter r1) where the convex portion 31a is formed, and the notch portion 31b is replaced with another flat portion 31c. The shape is uneven with the same diameter r2. For example, four notches 31b are formed.

  FIG. 4 is a diagram illustrating a detailed configuration of the gate 37 and a positional relationship with the pinch roller 31. FIG. 4 is a view of the gate 37 and the pinch roller 31 as viewed from above the sheet of FIG. As shown in FIG. 4, the gate 37 is fixed to the main body of the medium recovery device 5 by a shaft 37a and rotates as indicated by an arrow 37b. On the pinch roller 31 side of the gate 37, a pressing portion 38 having short teeth 38a, long teeth 38c, and notches 38b is formed.

  The short teeth 38 a are formed in a portion facing the flat portion 31 c of the pinch roller 31. The notches 38b are formed on both sides of the short teeth 38a. In particular, the side of the pinch roller 31 on which the convex portion 31a is located is formed so as to avoid the portion facing the convex portion 31a, and the pressing portion 38 does not contact the convex portion 31a. The long teeth 38c are formed in portions of the pressing portion 38 other than the short teeth 38a and the notches 38b.

  For example, at least the surfaces of the roller 21, the pinch roller 23, the roller 35, the pinch roller 33, and the roller 29 that are in contact with the medium are preferably formed of rubber, resin, or the like. In order to prevent the pinch roller 31 from being caught by the medium, the contact surface with the medium is preferably formed of a resin.

  Hereinafter, the switching state of the gate 25 and the gate 37 in the medium recovery apparatus 5 according to the present embodiment will be described with reference to FIGS. 5 to 7 are diagrams for explaining the switching of the conveyance path 15 in the medium recovery device 5. FIG. The gate 25 and the gate 37 can be switched by a magnet A and a magnet B (not shown), respectively, and the transport route can be changed as follows. Depending on the state of the two magnets, the usable conveyance path 15 is switched to the following three types.

1) Magnet A: Off, Magnet B: Off ... Conveyance path 15g (state of FIG. 5)
2) Magnet A: On, Magnet B: Off ... Conveyance path 15c → Conveyance path 15d → Conveyance path 15e (state of FIG. 6)
3) Magnet A: ON, Magnet B: ON: Conveyance path 15c → Conveyance path 15d → Recovery unit 43 (state in FIG. 7)
Hereinafter, the state 1) of the gate 25 and the gate 37 is referred to as a first state, the state 2) is referred to as a second state, and the state 3) is referred to as a third state.

  FIG. 5 shows a case where the medium is transported into the transport path 15g. As shown in FIG. 5, the gate 25 is in a state in which the conveyance path 15 d is closed, and the gate 37 is in a state in which the entrance to the collection unit 43 is closed. At this time, the medium 50 is sent out to the roller 21 and the pinch roller 23, and further conveyed while being sandwiched between the pinch roller 33 and the roller 35.

  FIG. 6 shows a case where the medium is transported into the transport path 15d and the transport path 15e. As shown in FIG. 6, the gate 25 is in a state where the transport path 15 d and the transport path 15 c are connected, and the gate 37 is in a state where the entrance to the collection unit 43 is closed. At this time, the medium 50 is sent out to the roller 21 and the pinch roller 23, and is temporarily retracted in a state where the medium 50 is sandwiched between the pinch roller 31 and the roller 29 and partly conveyed to the conveyance path 15e.

  FIG. 7 shows a case where the medium is collected by the collection unit 43. As shown in FIG. 7, the gate 25 is in a state of connecting the transport path 15d and the transport path 15c, and the gate 37 is in a state of closing the transport path 15e. At this time, the medium 50 is sent out to the roller 21 and the pinch roller 23, and is further sandwiched between the pinch roller 31 and the roller 29 and collected by the collecting unit 43.

  Hereinafter, the medium recovery operation of the medium recovery apparatus 5 according to the present embodiment will be described with reference to FIGS. 8 to 13. 8 to 13 are diagrams for explaining the medium recovery operation of the medium recovery device 5 when the medium recovered by the recovery unit 43 is sufficiently small. 8 to 13, the shielding part 39 of the gate 37 is not shown.

  As shown in FIG. 8, the medium 50 that has been transported through the transport path 15 a of the front stage unit 3 is sandwiched between the roller 21 and the pinch roller 23 and transported to the transport path 15 c of the medium recovery device 5. At this time, the two magnets A and B are both off, and the gate 25 and the gate 37 are in the first state.

  When collecting the medium 50 in the collecting unit 43, as shown in FIG. 9, first, the two magnets A and B are turned on, and the gate 25 and the gate 37 are in the third state. When the leading end of the medium 50 reaches the position of the sensor 27, the control unit 8 determines that the medium 50 has been conveyed by detecting that the sensor 27 is shielded.

  As shown in FIG. 10, the medium 50 is conveyed in the direction of the arrow 56 through the conveyance path 15 d and is sandwiched between the pinch roller 31 and the roller 29. As shown in FIG. 11, the medium 50 is conveyed in the direction of the arrow 60 by the rotation of the roller 29 and the pinch roller 31 and further conveyed into the collection unit 43, and is completely collected by the collection unit 43 as shown in FIG. Is done.

  As illustrated in FIG. 13, when the control unit 8 detects that the rear end of the medium 50 is conveyed into the collection unit 43 by the sensor 27, for example, when the rotation of the pinch roller 31 exceeds a certain number of steps. Next, the magnet B is turned off. That is, when it is considered that the medium 50 has passed the pinch roller 31, the magnet B is turned off. Thereby, the control unit 8 switches the gate 37 to the second state, and stops the rotation of the pinch roller 31 by stopping the application of the driving force to the roller 29, for example. Further, by turning off the magnet A, the gate 25 is rotated to be in the first state.

  Next, the medium recovery method according to the present embodiment will be described with reference to FIGS. 14 to 20, taking as an example the case where the recovery unit 43 has already recovered an amount close to the allowable amount. 14 to 20 are diagrams for explaining the operation of the medium recovery apparatus 5 according to this embodiment in detail. As shown in FIG. 14, it is assumed that the gate 25 and the gate 37 are in the third state. In the medium recovery device 5, when the medium is already recovered in the recovery unit 43, for example, a contact load may be generated at a place as indicated by a range 51, and the medium 50 may not be completely recovered by the recovery unit 43. .

  As shown in FIG. 15, after the passage of the medium 50 is detected by the sensor 27, the control unit 8 turns off the magnet B when, for example, the rotation of the pinch roller 31 exceeds a certain number of steps. However, since the medium 50 is still sandwiched between the pinch roller 31 and the roller 29, the shielding unit 39 does not enter the inside of the sensor 41, and the control unit 8 detects that the state has shifted to the second state. Can not. Therefore, the roller 29 and the pinch roller 31 continue to rotate. Further, the pressing portion 38 of the gate 37 presses the medium 50 against the pinch roller 31 in the direction of the arrow 62.

  As shown in FIG. 16, when the pinch roller 31 further rotates in a state where the medium 50 is pressed, the rear end of the medium 50 in the transport direction is disposed in the notch 31 b of the pinch roller 31 and fits. become. Then, as the pinch roller 31 further rotates, as shown in FIG. 17, the rear end of the medium 50 is applied with a driving force exceeding the contact load generated in the range 51 of FIG. As shown in FIG.

  Further, as shown in FIGS. 18 and 19, the medium 50 is conveyed in the direction of the arrow 64 as the pinch roller 31 rotates. During this time, as shown in FIG. 19, the long teeth 38 c press the medium 50 in the direction of the arrow 62.

  As shown in FIG. 20, when the medium 50 is completely collected by the collection unit 43, the pressing unit 38 of the gate 37 is not prevented from rotating by the medium 50, and further rotates in a direction to close the entrance of the collection unit 43. To do. Since the portion of the pressing portion 38 that faces the pinch roller 31 is the short tooth 38a and the notch 38b as described with reference to FIG. 4, the gate 37 is conveyed without being prevented from rotating by the pinch roller 31. The path 15d is rotated to a position where it is connected to the transport path 15e. At this time, the shielding part 39 provided in the gate 37 enters the inside of the sensor 41. The control unit 8 detects that the gate 37 is completely rotated by the shielding of the sensor 41 and has shifted to the second state. The control unit 8 determines that the medium 50 has been completely collected in the collection unit 43 by detecting that the gate 37 has completely rotated. Further, the control unit 8 turns off the magnet A and switches the gate 25 to the first state.

  After the control unit 8 detects the medium 50 by the sensor 27, for example, when the rotation of the gate 37 is not detected by the sensor 41 when the rotation of the pinch roller 31 exceeds a certain number of steps. The medium 50 is preferably turned on and off so that the medium 50 can be easily caught by the notch 31b of the pinch roller 31.

  The above operation will be further described with reference to FIG. FIG. 21 is a flowchart showing the operation of the medium recovery device 5. As shown in FIG. 21, first, the control unit 8 turns on the magnets A and B. For example, as shown in FIG. 9, the gate 25 and the gate 37 and the third state for collecting the medium 50 into the collection unit 43 (S101). For example, as shown in FIG. 9, the medium 50 is sandwiched between the pinch roller 23 and the roller 21 and starts moving (S102).

  For example, as shown in FIG. 9, when the medium 50 is conveyed to the position of the sensor 27 for medium detection, the control unit 8 detects that the sensor 27 is shielded (S103). For example, as shown in FIG. 11, when the rear end of the medium 50 passes the sensor 27, the control unit 8 detects the passage of the medium 50 because the sensor 27 is not shielded (S104).

  The control unit 8 conveys the medium 50 from the passage of the medium 50 until, for example, a predetermined number of steps of a motor (not shown) that rotates the roller 29 is counted (S105). Then, the control unit 8 gives an instruction to turn off the magnet B and shift the gate 37 to the second state in which the collection unit 43 is closed (S106). Further, the control unit 8 further conveys the medium 50 until the fixed number of steps of a motor (not shown) that rotates the roller 29 is counted (S107). During this time, as shown in FIGS. 15 to 19, the convex portion 31 a of the pinch roller 31 pushes the rear end of the medium 50, thereby conveying the medium 50 toward the inside of the collecting unit 43.

  The control unit 8 determines whether or not the sensor 41 is shielded by the shielding unit 39 (S108). If the control unit 8 determines that the sensor 41 is shielded, the control unit 8 stops the rotation of the roller 29 and the pinch roller 31 and turns off the magnet A. The state is set to 1 and the process ends (S109). In S108, while it is not detected that the sensor 41 is shielded, the magnet B is turned on (S110) and then turned off (S106).

  In the embodiment described above, the pinch roller 31 is an example of the roller of the present invention, the roller 29 is an example of a counter roller, the sensor 27 is an example of a medium detection unit, and the sensor 41 is an example of a recovery detection unit. It is. The conveyance path 15e is an example of a temporary retreat path. The gate 37 is an example of a path switching unit of the present invention.

  As described in detail above, in the medium collection device 5 of the automatic transaction apparatus 1 according to the present embodiment, the pinch roller 31 at the entrance of the collection unit 43 is provided with the convex portion 31a and the notch portion 31b. The convex part 31a and the notch part 31b are provided on one side of the pinch roller 31 in a direction orthogonal to the medium transport direction. Two pinch rollers 31 were provided at intervals in a direction orthogonal to the transport direction.

  The transport destination from the transport path 15d is not only the collection unit 43 but also a transport path 15e that can be used for temporary retreat. A pressing portion 38 and a shielding portion 39 are provided in the gate 37 that switches the conveyance destination from the conveyance path 15d between the collection unit 43 and the conveyance path 15e. Further, a sensor 27 that detects the passage of the medium 50 is provided in the transport path 15d, and a sensor 41 that detects the movement of the gate 37 by the shielding unit 39 is provided.

  With such a configuration, when the medium 50 is collected into the collection unit 43, the rear end of the medium 50 can be pushed by the convex portion 31a. Therefore, even when a medium close to the allowable amount has already been collected in the collection unit 43, it is possible to apply a transport force that exceeds the contact load with the medium already stored, and to reliably collect the medium. Can do.

  The convex part 31a and the notch part 31b are provided on one side of the pinch roller 31 in a direction orthogonal to the medium transport direction. Therefore, the pinch roller 31 can be easily manufactured, and even when a plurality of pinch rollers 31 are provided, it is only necessary to create the same shape. Two pinch rollers 31 are provided in a direction orthogonal to the medium conveyance direction. Thereby, the medium to be conveyed can be conveyed in a wave shape, and the conveyance force can be improved.

  The pressing portion 38 of the gate 37 is formed in a comb-teeth shape, and in particular, a portion facing the pinch roller 31 is a short tooth 38a and a notch 38b. Therefore, the short teeth 38 a continue to push the flat portion 31 c of the pinch roller 31 until the medium 50 leaves the pinch roller 31 and is reliably collected by the collecting unit 43. As a result, the gate 37 cannot rotate to a position that reliably closes the entrance to the collection unit 43 until the medium 50 leaves the pinch roller 31. Therefore, by detecting that the shielding unit 39 shields the sensor 41, it is possible to detect that the medium 50 has been reliably collected by the collecting unit 43.

  As described above, it is possible to prevent a medium that has not been completely collected by the collection unit 43 from being taken out, for example, when the temporarily retracted medium is discharged. At this time, since the transport path 15e for temporary evacuation is provided, there is an effect of further preventing take-out during discharge.

  As described above, even when a number of media close to the allowable amount is already stored in the collection unit 43, the collection unit 43 can be reliably collected, so that the performance of the passbook printer can be improved. It is also possible to make the number of recoverables reduced by the reduction of the space equal to or more than the conventional one.

  In addition, since the transport path 15e for temporary evacuation and the switching gate 37 are newly added, even if the space of the recovery unit 43 is smaller than the conventional one, recovery failure can be reduced. Can be equivalent or better.

  The present invention is not limited to the embodiments described above, and various configurations or embodiments can be adopted without departing from the gist of the present invention. For example, both the roller 21 and the pinch roller 23 may be rotated. For example, the pinch roller 23 is rotated by applying a driving force in accordance with the conveyance direction of the medium. The driving force may not be applied. For example, four notches 31b are formed, but other numbers may be used. In the example of FIG. 4, the long teeth 38 b are also formed in a comb-like shape, but, for example, the two pinch rollers 31 may be continuous.
