Then, the pin 14s12 is swinging pieces 14s ₁ to abut the upper end of the circumferential slit 13b1 is rotated clockwise by the urging force of the torsion coil spring (not shown). Thus, the pin 14s ₁₂ releases the pressing raised against the rear end portion of the elevation frame 12. Accordingly, the lifting table 12 is raised by the urging force of the urging unit 12p, and presses the uppermost surface of the stacked banknote M against the lower surface of the pair of claw portions 13a of the elevating plate 12 (see FIG. 15A).

  When the banknote storage / discharge device 10 enters this storage state, as shown in FIG. 15B, the banknote M3 sent from the outside is moved into the banknote storage chamber 11a by the pair of transport rollers 105a and 105b rotating in the arrow direction. The bill M3 is conveyed, and is stored in a state of being placed on the pair of claw portions 13a, as shown in FIGS.

  According to this bill storage / discharge device 10, the lifting mechanism 14 raises and lowers the lifting plate 13 above the discharge rollers 15 so that the banknotes on the lift 12 are pressed against the discharge rollers 15 (see FIG. 8 ( A) and (B)), the lifting plate 13 and the lifting table 12 are lowered to enter a lower intermediate state (see FIG. 11) in which the press-contact of the bills by the discharge roller 15 and the lifting table 12 is released. It is configured to be in a housed state in which the elevating plate 13 and the elevating table 12 are lowered so as to press the bills on (see FIGS. 15A and 15B).

[Transition from storage state to discharge state]
FIG. 17A is a first operation explanatory view showing a raised state of the shelf-like structure in the banknote storage / discharge device of FIG. 3, and FIG. 17B is a second operation explanatory view following FIG. FIG. 18A is a first operation explanatory diagram showing a rising state of the shelf-like structure viewed from the back side, and FIG. 18B is a second operation explanatory diagram following FIG. (C) is a third operation explanatory diagram subsequent to (B).

When the bill housing and discharging device 10 is shifted to the discharge state from the stored state, the roller 14b ₁ along with gear G of the power transmission portion 14b is 180 ° rotated counterclockwise (see FIG. 13 and 6). At this time, the roller 14b ₁ is a long hole 14a in _one of the slide plate 14a from the center to the other end side rises while moving further toward the other end side to the center, a shelf-like structure including a slide plate 14a The entire 13x rises to the uppermost position.

During this time, the roller 14s ₁₃ of pressing mechanism 14s swinging pieces 14s ₁ of abuts on the lower end outer periphery linear contact piece 14s _2. Then, the contact piece 14s ₂ against the urging force of the torsion coil spring 14s ₂₁ (see FIG. 7) is rotated by being pushed by the roller 14s ₁₃ clockwise. On the other hand, the swing piece 14s ₁ is restricted to clockwise rotation. Thus, the swing piece 14s ₁ is elevated without changing the attitude of the stored state, the roller 14s ₁₃ climbs over the abutting piece 14s _2. Thereafter, the contact piece 14s ₂ by the biasing force of the torsion coil spring 14s ₂₁ returns to the original position shown in FIG.

  Therefore, while the banknote storage / discharge device 10 shifts from the storage state to the discharge state, the stacked banknotes M rise while being sandwiched between the elevating platform 12 and the pair of claw portions 13a, and the banknotes M3 during storage are stored in the pair of claw portions. It rises while resting on the part 13a. Then, as shown in FIG. 17A and FIG. 18A, the stored bill M3 comes into contact with the discharge roller 15 and the pickup roller 104.

  Thereafter, as the shelf-like structure 13x rises, the pair of claw portions 13a rises outside the pair of bill sorting plates 16 as shown in FIG. At this time, since the upper surface of the bill M3 is in contact with the discharge roller 15, the pickup roller 104, and the pair of bill separating plates 16, both ends in the width direction of the bill M3 are pushed up by the pair of claws 13a and curved.

  When the pair of claw portions 13a further rises, both ends in the width direction of the banknote M3 pass through between the pair of claw portions 13a, as shown in FIGS. 17B and 18C. As a result, the entire banknote M3 is placed on the uppermost position of the stacked banknote M, and the transition to the discharge state is completed.
