ABSTRACT:
A phonograph cover is coupled to a tone arm assembly such that movement of the cover to its open position automatically retracts the needle of the tone arm assembly from the record in any selected position of the tone arm assembly on the record playing portion of the record. Movement of the cover to its closed position automatically causes the needle to engage the record in any selected position of the tone arm assembly on the record playing portion of the record.
The tone arm assembly is further coupled to the phonograph turntable drive means such that the drive means is actuated upon movement of the tone arm assembly onto the record playing portion of the record. The drive means is deactuated upon movement of the tone arm assembly to a rest position located outside of the playing portion of the record.
