| (54) | Coin box storage structure |
| (57) A coin box storage structure includes a coin box, a safe chamber, a shutter plate,
a lock lever, a tumbler mechanism, and a dampening member. The shutter plate is swingably
disposed in a lid, has a projection, and opens a coin storage port against a biasing
force when the coin box is stored in the safe chamber. The lock lever has a ratchet
portion engaged with the projection of the shutter plate to keep closing the coin
storage port when the coin box is removed from the safe chamber. The lock lever is
pressed and pivoted by the shutter plate when the coin box is stored in the safe chamber.
When the lock lever is pivoted by a predetermined angle or less during opening of
the lid, the tumbler mechanism reverses the lock lever to disengage the ratchet portion
from the projection of the shutter plate to set the shutter plate in a preset state.
When the lock lever is pivoted by the predetermined angle or more during storage of
the coin box into the safe chamber, this mechanism reverses the lock lever to set
the ratchet portion and the projection of the shutter plate in an engagement standby
state. The dampening member inhibits to apply a pivot force to the lock lever in an
initial period of pivotal movement of the lid and pivots the lock lever in pivotal
movement of the lid by an angle exceeding the predetermined angle. |
