A handle 55 (see FIG. 9) fixed to the back surface of the case 1 engages with a groove 55 formed around the outer peripheral surface of the handle 9 to prevent the handle 9 from falling off.

The operation of the locking device for the coin locker configured as above will be described. Normally, when a user uses a coin locker, the vertical axis 45b of the handle lock pin 45 is engaged with the locking hole 10 of the handle 9 and the handle 9 cannot rotate (see FIG. 2). ), The locking groove 17 of the rotor 11b of the customer lock 11 engages with the small diameter hole 35 of the stopper plate 31 so that the customer lock 11 cannot be pulled out, and the locking rod 25 protruding from the case 1 is provided on the door. The locker door is locked (see Fig. 1).

In this state, in order to unlock the rocker door with the customer lock 11, the customer key K inserted in the customer lock 11 is rotated in the unlocking direction. When the customer key K is rotated in the unlocking direction, the cam 21 is rotated in the same direction, and the locking rod 25 that engages with the drive pin 27 of the cam 21 is retracted into the vertically elongated hole 28 of the case 1 to lock the locking rod. The engagement between 25 and the door is released, and the door can be opened.

On the other hand, in the case of emergency unlocking with the management lock 51, the management key inserted into the key hole of the management lock 51 uses the management key rotor 51a, the rotation restricting cam 52, and the lock stopper cam. When 53 is rotated clockwise in FIG. 3, the side surface of the cam piece 53a pushes the horizontal shaft 47 of the handle lock pin 45 downward, the handle lock pin 45 descends, and the locking hole of the handle 9 moves. Since the handle 9 is separated from the handle 10, the handle 9 can be rotated (see FIG. 3).

When the handle 9 is rotated with the fingertip in the unlocking direction of the customer lock 11, the entire customer lock 11 is rotated with the handle 9 in the unlocking direction, and the rotor 11b of the customer lock 11 is rotated. As a result, the cam 21 rotates in the same direction, and the locking rod 25 that engages with the drive pin 27 of the cam 21 is retracted into the case 1 so that the door can be opened (see FIG. 4). However, since the locking groove 17 at the rear end of the rotor 11b of the customer lock 11 is engaged with the small diameter hole 35 of the stopper plate 31, there is no possibility that the customer lock 11 will fall out.

When the handle 9 is rotated in the unlocking direction, the lock hole 10 is moved to the right, so the handle lock pin 45 cannot be engaged with the lock hole 10 (see FIG. 5). ). That is, even if the management lock 51 is returned to the old position, the customer lock 11 is held in the unlocked state. Then, when the customer lock 11 is returned to the locked position together with the handle 9, the vertical axis 45b of the handle lock pin 45 is engaged with the locking hole 10.

Further, when the customer lock 11 is replaced, the rotor 51a of the management lock 51, the rotation restricting cam 52 and the lock stopper cam 53 are locked by the management key inserted into the key hole of the management lock 51. 6, when it rotates counterclockwise in FIG. 6, the inner peripheral surface of the cam piece 53a pushes the interlocking pin 54 to the left, and the stopper plate 31 moves to the left, causing the small diameter hole 35 to engage the rotor 11b. The lock 11 can be removed from the stop groove 17 and the customer lock 11 can be taken out from the handle 9.
