Document Type and Number:
Japanese Patent JP2688429
Kind Code:
B2
Abstract:
A safe of the present invention is easily locked or unlocked by the rotational force of a drive motor in accordance with a signal input from the outside of the safe. A locking mechanism is provided within the door. A lock bar is provided with a lock bolt on one end thereof which protrudes from the door and effects locking engagement between the door and the safe body. At ordinary time, the lock bolt is urged to the locking engagement. The drive motor is controlled by a control circuit which receives a safe open/close command signal from the outside. A driving means is revolved by the drive motor and when it engages a drive arm provided on the lock bar, the driving means moves the lock bar against the urging force, thereby releasing the locking engagement of the lock bar. Since secure locking/unlocking operation of the safe is performed by driving the drive motor only to move the lock bar in the direction in which the lock bar is against the urging force, it is possible to simplify the structure of the safe having a motor-driven locking mechanism.
