ABSTRACT:
A code lock device comprising an actuator responding to a release operation and a locking operation, and an actuation which performs reciprocating motion and normal and reverse rotation. A plurality of dials for setting a release code series and a plurality of drive plates each of which responds to each dial and integrally rotates with each actuation shaft are provided on the actuation shaft, and a dial enforced reset mechanism is equipped between each drive plate and each corresponding dial. This dial enforced reset mechanism makes each drive plate and each corresponding dial engage each other by an engaging means in response to reciprocating motion and normal and reverse rotation of the actuation shaft in the case of the release operation or the locking operation, and makes each dial forcibly rotate to break the release code series in response to rotation of the actuation shaft.
