ABSTRACT:
A plunger-latch mechanism for an optical disk drive has a plunger type solenoid, a plurality of resilient members, a connecting member, a latch, a wedge and a rotary member. While the tray is pushed into the casing, a mutual movement between the rotary member and the latch cause the latch rotate to be locked by the wedge. Since the plunger type solenoid opens the latch without resistance to the resilient force of the resilient members, the electric power required to open the latch is greatly reduced. Moreover, the locking force between the latch and the wedge is significantly increased. Therefore, the performance of the plunger-latch mechanism for optical disk drive is improved.
