Device for locking front cover of bank note container box for use in automatic money depositing and disbursing machine

摘要

A device for locking a front cover attached to a bank note container box to cover the opening of the box. The device securely locks the front cover in the closed condition when the box is removed from the automatic money depositing and disbursing machine, and releases the front cover automatically when the box is held in position within the machine. The device comprises, in combination, an opening and closing cam and an unlock cam mounted to the machine body, and a lock member and a first unlock lever mounted to the side plate of the box. When the box initially inserted in the machine body is moved to be pulled out, the unlock lever is raised by the unlock cam so that the lock member releases the front cover from the locked condition in which it is locked in the open position. Thereafter the front cover is slowly closed by the action of the opening and closing cam. Then the lock member is moved by the action of a biasing spring to the position for locking the front cover. In a further preferred embodiment, double lock means are provided for safe carriage of the box by hand. The double lock means comprises a further lock lever and an unlock member operatively associated with said first unlock lever.
