At this time, the front end of the pin 51 of the urging mechanism portion 50 presses the inner surface 30a ₂ of the cover body 30a by the urging force of the elastic member 53 and is in contact with the arcuate surface portion 31a ₁ of the contact member 31a.

  In the closed state of the coin collective slot cover 30, when the transparent cover 33 is raised and coins are inserted one by one into the coin insertion slit 101, the coin transport unit 106, the drum unit 107, the coin identification unit 102, and the coin transport unit 103. And then sent to the first chamber or the second chamber of the coin storage and withdrawal device 1 corresponding to the denomination (see FIGS. 1 and 2).

  When the coins stored in any one of the coin storage / dispensing devices 1 in the automatic change depositing / dispensing machine 100 are reduced, the administrator unlocks the lock unit 40 and opens the coin batch slot cover 30, It is necessary to replenish a plurality of coins in a lump slot 131. At this time, as shown in FIG. 4, the administrator raises the transparent cover 33 and inserts the square concave key K into the square convex key fitting portion 41 a to resist the biasing force of the operation shaft biasing member 44. Then, the operation shaft 41 is rotated about 90 ° in one direction (for example, clockwise) (see FIG. 4).

As a result, as shown in FIG. 8B, the flat surface of the recess 41d ₂ of the operation shaft 41 changes from the horizontal state to the vertical state. At this time, one corner 41d ₃ between the recess 41d ₂ and the arc 41d ₁ rises while drawing an arc orbit, so that the slidable contact 42a of the locking member 42 comes into sliding contact with the corner 41d ₃ . It is pushed up while. Thus, the locking portion 42b of the locking member 42 moves upward against the urging force of the locking member urging member 43, and is released from the pair of left and right locking recesses 133 to be unlocked.

Therefore, the radius r ₁ of the sliding contact surface portion 41 d of the operation shaft 41 becomes the moving distance Q of the locking member 42. The moving distance Q may be any distance that allows the locking portion 42b to get over the locking recess 133. For example, the moving distance Q is set to be greater than or equal to the depth D of the locking recess 133. It is set long. Even if the moving distance Q is set to be slightly shorter than the depth D, if the outer surface of the locking portion 42b and the upper end of the locking recess 133 are rounded, the coin collective slot cover 30 will be described later. Thus, when the pop-up is performed, it is possible to get over the sliding portion 42b while sliding on the upper end of the locking recess 133.

Then, when the key K is rotated and pulled out from the key fitting portion 41a, the coin collective slot cover 30 that has been pushed forward by the pin 51 pops up as shown in FIG. At this time, the attachment shaft 31 and the abutting member 31a are rotated about 180 ° integrally with the coin collective slot cover 30. During this time, since the center of curvature of the arc surface portion 31a ₁ coincides with the axis P of the mounting shaft 31, the pin 51 protrudes forward while being slidably contacted with the arc surface portion 31a ₁ without being pushed up by the contact member 31a. To do. Accordingly, both the pop-up of the coin collective slot cover 30 and the removal of the mounting shaft 31 from the concave receiving portion 132 are prevented by the pin 51.

Further, when the key K is pulled out from the key fitting portion 41a, the operation shaft 41 is rotated in the opposite direction by the urging force of the operation shaft urging member 44. That is, the operation shaft 41 changes from the state of FIG. 8B to the state of FIG. At this time, the locking member 42 urged toward the operation shaft 41 by the urging force of the urging member 43 for the locking member moves as the corner portion 41d ₃ of the operation shaft 41 moves while drawing an arc orbit. The sliding contact portion 42a moves while being in sliding contact with the corner portion 41d ₃ and is fitted into the concave portion 41d ₂ of the operation shaft 41.

  After coin replenishment, the coin collective slot cover 30 is lifted and closed, whereby the left and right engaging portions 42b of the engaging member 42 of the lock portion 40 slide on the left and right ribs 130 of the housing 100a. The locking recess 133 is depressed and locked. Thereby, the coin collective slot cover 30 is locked again by the lock unit 40.

(Embodiment 2)
FIG. 11A is an explanatory diagram illustrating the locked state of the lock portion in the second embodiment, and FIG. 11B is an explanatory diagram illustrating the unlocked state of the lock portion in the second embodiment. In FIGS. 11A and 11B, elements similar to those in FIGS. 8A and 8B are denoted by the same reference numerals.
In the case of the second embodiment, the configuration is the same as that of the first embodiment except that the shape of the sliding contact surface portion 141d of the operation shaft 141 of the lock portion 140 is different.

In operation shaft 141 of the second embodiment, the sliding surface portion 141d has an arc portion 141d ₁ around the axis G _2, the convex portion 141d ₂ projecting radially outward than the arc section 141d ₁ Thus, the cross-sectional shape is formed into a cam shape. Specifically, if the rotation range of the operating shaft 141 is 90 °, the top of the convex portion 141d ₂ is the locking member when the operating shaft 141 is rotated 90 ° as shown in FIG. It is formed in a cam shape that contacts the sliding contact portion 42a. The distance obtained by subtracting the radius r ₂ of the sliding contact surface 141d from the distance T from the axis G ₂ to the top of the convex portion 141d ₂ becomes the moving distance Q of the locking portion 42b.
Although not shown, also in the second embodiment, when the key is pulled out from the key fitting portion after unlocking, the operation shaft 141 is rotated in the opposite direction by the urging force of the operation shaft urging member. That is, the operation shaft 141 is changed from the state of FIG. 11B to the state of FIG.
