PROBLEM TO BE SOLVED: To provide a mechanism which reliably locks a drawer with a simple structure, is unlocked with light force by pushing the front surface of the drawer, so as to simultaneously perform an auxiliary operation to open the drawer, and may be set to automatically open the drawer depending on the setting of a push spring. SOLUTION: When the drawer is pushed in a lock state, a pin of a mobile stopper B 6 comes off a mobile stopper A 5 and goes down along a fixing stopper 4 to perform unlock. When pushing force is released, the drawer is pushed forward by the push spring and automatically opened. In this case, the pin of the stopper B 6 is moved backward, while lifting up the lower part of the stopper A 5. Then the stopper A 5 is lowered. When the drawer is pushed in again, the pin of the stopper B 6 is moved upward along the upper side of the stopper A 5. When the drawer is pushed to the innermost part, the pin of the stopper B 6 is stopped in the upper part of the fixing stopper 4. Afterward, the pushing force is released so as to allow the drawer to be pushed out forward by the push spring and also to be stopped the stopper A by 5 since the pin of the stopper B 6 comes off the upper part of 4 and goes downward. Thus, the initial lock state is restored. COPYRIGHT: (C)2005,JPO&NCIPI
