Lid interlock apparatus for a disc record player

In a playback system for recovering prerecorded signals by a signal pickup from a disc record rotatably mounted on a turntable, the playback system including a lid pivoted on a base for movement between a closed position and a released position, and a signal pickup housing reciprocably mounted on the base for travel between a standby mode and a playback mode, a lid interlock apparatus comprising:

• a lid release lever movably mounted on the base;
• a lid latch member for selectively releasing the lid in response to manipulation of the release lever, the latch member comprising:
• a plate pivotally mounted on the base for movement between (1) a protruding position, and (2) a retracted position;
• a first tab secured to the plate for (a) engagement with the lip provided in the lid when the plate is in the protruding position, and (b) releasing the lip when the plate is in the retracted position, if the lid were closed;
• a second tab secured to the plate for engagement with one end of a slide member reciprocably mounted on the base, and means for biasing the plate in the protruding position;
• a cam mounted on the slide member for movement between (a) a first condition intercoupling, and (b) a second condition decoupling, the release lever and the slide;
• and wherein when the cam is in the second condition the latch member structure does not obstruct movement of the release lever;
• and
• means interconnecting the cam and the signal pickup housing, wherein the interconnecting means is effective for moving the cam (one) into the first condition when the housing is in the standby mode whereat the latch member plate responsive to the movement of the slide member caused by manipulation of the lever releases the lid, and (two) into the second condition when the housing is in the playback mode whereat manipulation of the release lever is ineffective to release the lid, if the lid were closed.
