Abstract

Abstract A relatively simple toy phonograph for playing interchangeable disc records including a control lever with an eject knob for ejecting a record and a replay knob for replaying it, both on the same surface as the slot through which the record moves. When the replay knob is depressed, a first camming portion thereon pivots a lever that lifts the tone arm and a second portion thereon moves the tone arm to the outer edge of the record to replay it. When the eject knob is depressed, it pivots an eject lever which has camming surfaces that raise a spindle to release the record, pivot the lever that lifts the tone arm, push against the rim of the record to eject it, push the tone arm to the periphery of the turntable, and open the motor energizing circuit. When a new record is inserted, it pushes the eject cam to automatically start the mechanism to play the new record. An electrically conductive spring member is provided that has one arm at the battery case for contacting a battery terminal, another arm in contact with an electric motor terminal, and a pair of additional arms that function as mechanical springs.
