ABSTRACT:
The present invention relates to a novel record player adapted for toys. The record player has a casing with a lid pivotally mounted to the upper surface. A turntable with a phonograph record attached thereto is rotatably secured to the underface of the lid. A pickup is mounted within the casing to allow a stylus to be reciprocatively movable along the grooves in the downward facing record. A mechanism for harmonizing the stylus pressure is provided on the upper portion of the casing consisting of a lever pivoted opposite the lid pivot and a spring to urge one end of the lever into engagement with the lid. Consequently, a part of the weight of the upper lid, turntable and record is applied to the stylus so that appropriate stylus pressure is obtained. At the end of one cycle of playback operation, the end of the lever is depressed to lift the lid disengage the stylus from the grooves and allow a spring to return the pickup to the original position.
