Drop safe

A drop safe for receiving and temporarily storing currency or other valuables from a cash register or point-of-sale terminal. The drop safe uses bill acceptors to transfer cash into sealed cassettes within the safe. An envelope drop assembly allows transferring into the safe currency or non-cash items not accepted by the acceptor. The drop safe door has a door control assembly including a gas spring to counterbalance the weight of the door for controlled movement during opening. The door is locked by a pair of door bolts linked to a lock cam, which is secured by a dead bolt against movement. An electronic control unlocks the dead bolt in response to entry of correct numbers, allowing a rotary dial of the outside of the safe to move the lock cam and release the door bolts. The drop safe includes a processor programmed to control the unlocking operation and to maintain and produce various reports of deposits into the safe, enabling easy correlation of those deposits with business-day operation of the drop safe.
