Claim:
A bill processing apparatus comprising: a bill receiver that receives a bill inserted and delivered through a bill insertion slot; a bill collection slot that collects the bill received in the bill receiver; an openable shield plate that shuts the bill collection slot; a movement device that moves the bill receiver toward the bill collection slot; and a lock device that locks a shut state of the shield plate to be released, wherein the lock device is mechanically operated in connection with the movement of the bill receiver that is moved by the movement device, wherein the lock device contacts the bill receiver that is moved toward the bill collection slot by the movement device, thereby releasing a lock of the shield plate shut, wherein the lock device comprises a pivot member that is pivoted between a lock position at which the lock device is opposite to the shield plate to obstruct the shield plate from being opened, and a lock release position at which the lock device retreats from the shield plate to allow the shield plate to be opened, and wherein the pivot member has a first interlocking operation part that is protruded into a movement path of the bill receiver and is pivoted from the lock position to the lock release position as the bill receiver to be moved toward the bill collection slot by the movement device is contacted to the first interlocking operation part.
