The set cam fixed to the rotating member may be provided with a pushing projection for pushing the stopper in the immersion direction when the set cam is rotated.

[0008]

In the lock mechanism of the coin storage box configured as described above, before being mounted on the vending machine, the shutter stopper engages with the one-way clutch of the closed shutter,
The shutter is locked in a closed state. When this coin storage box is inserted into the storage box mounting member, the projection of the shutter lever comes into contact with the guide lever of the storage box mounting member. Since the shutter is locked in the closed state, the shutter lever engaged with the shutter cannot rotate, and the projection of the shutter lever pushes the guide lever, and the guide lever moves away from the front wall against the urging force. Rotate in the direction.

When the coin storage box is completely inserted, the stopper urged in the direction protruding from the coin storage box projects and engages with the storage box mounting member, making the coin storage box unremovable. On the other hand, the key of the storage box mounting member is inserted into the mounting check lock, and the rotating member becomes rotatable. At this time,
The shutter is still closed, and when the distributor operates the rotating member in the shutter opening direction, the rotating member rotates in a direction without play with respect to the start cam and directly drives the start cam to start the start cam. The cam pushes the shutter stopper, the engagement between the shutter stopper and the one-way clutch of the shutter is released, and the shutter becomes movable.

When the shutter becomes movable, the shutter lever engaged with the shutter becomes rotatable, so that the guide lever which has been pushed in the direction opposite to the urging force pushes back the shutter lever, and the shutter which engages with the shutter lever. Moves in the opening direction and opens the coin receiving slot. Thus, when a coin is inserted into the vending machine, the coin falls through the coin receiving slot into the coin storage box.

[0011] The coin storage box full of coins is removed by a collection and delivery person who patrols each vending machine, and a new empty coin storage box is attached. To remove the coin storage box, first, when the rotating member is rotated in the shutter closing direction, the set cam is rotated integrally with the rotating member, and the stopper pushed by the set cam moves to the coin storage box. And the engagement with the storage box mounting member is released, and the coin storage box can be removed.

On the other hand, since the rotating member rotates in a direction with play with respect to the start cam, the start cam does not rotate. Therefore, the shutter stopper remains engaged with the one-way clutch of the shutter, and the shutter is immovably restrained in the opening direction and can move only in the closing direction. As the coin storage box is removed, the shutter is closed, and when the removal is completed, the shutter is locked in the fully closed state.

After the coin storage box containing the coins is extracted, a newly empty coin storage box is mounted on the storage box mounting member. The coin storage box containing the coins is delivered to the manager, the manager unlocks the manager's lock, opens the coin storage box, collects coins, and locks the management lock, It can be attached to vending machines again.
