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.

Abstract: An electrical device with a revolvable display panel. The electrical device comprises a housing, a guidance means, a sliding means, and a revolving means. The housing has a plurality of housing walls. One of the housing walls contains an opening. The guidance means is set inside the housing close to the opening. The sliding means is guided by the guidance means to slide into an inside position and an outside position of the housing. The revolving means has a display panel and is pivotally connected to the sliding means. When the sliding means is in the inside position, the sliding means with the display panel of the revolving means is situated inside the housing. When the sliding means slides into the outside position, the sliding means with the display panel is situated outside of the housing, thus the display panel can revolve to change an angle of the display panel.
