ABSTRACT:
A lid is pivoted to the base of a record player for movement between a closed position and an open position. A leaf spring is secured to the base at one end thereof. A detent is mounted to the remote end of the leaf spring for movement between (1) a protruding condition subject to engagement with the lid when closed, and (2) a retracted condition releasing the lid if closed. A plunger is reciprocably mounted for cooperation with a lid release button. A slide is movably mounted in the base adjacent the leaf spring for movement between (a) a position interposed, and (b) a position not interposed, between the plunger one end and the leaf spring. The plunger responsive to operation of the release button moves the detent to the retracted condition, via the slide and the leaf spring, if the slide is in the interposed position. If the slide is not interposed, the release button is ineffective to actuate the detent. A linkage is provided between the cam and the signal pickup carriage of the player for moving the slide to the interposed position and not-interposed position when the carriage is, respectively, in a standby mode and a playback mode thereby preventing opening of the lid during playback.
