When the stack cam 47 rotates halfway in this way, the stack plate 33 moves forward by the stroke 2a and is pushed forward of the side surface base 24 (conveyance path 8) as shown in FIGS. The bills P whose both ends in the width direction are held by the pair of left and right side bases 24 are pushed forward by the stack plate 33. Then, the banknote P is detached from the side surface base 24 and pressed and accumulated on the cover base plate 29 of the banknote storage unit 30, and is substantially central in the longitudinal direction along the lateral V shape of the cover base plate 29 as viewed from the side. Are stored in the banknote storage unit 30 in a curved state.

  When the stack cam 47 rotates 90 ° in the direction of the arrow from the state shown in FIG. 11C, the cam roller 49 is positioned at the upper limit of the cam groove 36a as shown in FIG. 11D, and the stack plate 33 is shown in FIG. When the stack cam 47 retreats by 90 ° from the position shown in (c) and the stack cam 47 further rotates 90 ° in the direction of the arrow, the cam roller 49 moves to the center (vertex) of the cam groove 36a as shown in FIG. 11 (a). Further, the stack plate 33 is further retracted by the stroke a and returned to the initial position shown in FIGS.

  As described above, when the stack cam 47 makes one rotation, the stack plate 33 moves forward from the initial position by the stroke 2a, pushes out the banknote P and accumulates it in the banknote storage unit 30, and then moves back by the stroke 2a to the initial position. Return to. The stack plate 33 reciprocates linearly in a state where the stack plate 33 is kept horizontal by the pantograph function of the links 34 and 35.

  Thus, by repeating the operations described above, the banknote P is sequentially stored in the banknote storage section 30 as shown in FIGS. 5 and 7 with its substantially central portion in the longitudinal direction curved. In the embodiment, as described above, the ribs 24a project from the curved apexes of the pair of left and right side bases 24 that form the transport path 8 toward the banknote storage section 30 as described above. Even in a state where a large number of banknotes P are stored in the section 30, the interval between the banknotes P transported in the transport path 8 and the large number of banknotes P already stored in the banknote storage section 30 is defined by the ribs 24a. Can be spread. For this reason, contact with the banknote P currently conveyed by the conveyance path 8 and the banknote P already accommodated in the banknote accommodating part 30 is prevented, and the banknote P is conveyed along the conveyance path 8 smoothly.

  As mentioned above, in the banknote identification device 1 according to the present invention, the banknote P is stored in the banknote storage section 30 in a curved state, and therefore the size of the banknote storage section 30 is kept below the longitudinal dimension of the banknote P. The bill identifying apparatus 1 can be reduced in size and size, and the bill identifying apparatus 1 can be installed in a place where the bill identifying apparatus 1 cannot be installed conventionally. can get.

  In particular, in the present embodiment, the banknote P is stored in the banknote storage unit 30 with its substantially central portion in the longitudinal direction curved, so that the banknote P is not significantly affected by wrinkles such as folds. The effect that P can be stably accommodated in the banknote accommodating part 30 is acquired. Further, since the bending saddle due to the curved storage of the banknote P is at the substantially central portion in the longitudinal direction, it is not necessary to align the direction of the banknote P on the side of the bending saddle. Furthermore, the bending wrinkle of the banknote P can be easily corrected by pressing the substantially central portion in the longitudinal direction of the banknote P that is curved.
