Document Type and Number:
Japanese Patent JP3966568
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To easily shut drawers even when a lock is operated for closure with a part of the drawers kept open, and unlock all the drawers even upon the occurrence of a failure in an electrically locked state.
SOLUTION: A spring 34 having an energizing force weaker than the axial holding force of an electromagnetic solenoid 29 is provided between the electromagnetic solenoid 29 and an operation lever 26 so as to energize a shaft 29a in a moving direction at the time of locking. As a result, a drawer opened at the time of locking can easily shut, and all drawers are automatically locked after the drawer is shut. Also, the operation lever 26 is provided with balancing means with an elevation lever 6. According to this construction, even when an electromagnetic solenoid having a small axial shrinkage force is used, the operation lever 26 is properly moved for causing the vertical travel of the elevation lever 26.
