Abstract
A head plate operating mechanism for a cassette tape player has a head plate carrying a magnetic head and movably mounted on a frame for movement between non-play and play positions. A power-assisting notched gear having a crank pin on a rotation surface thereof rotates when a tape cassette is loaded into the player. A slide member movably connected to the head plate is actuated to move by slidably contacting with the crank pin of the rotating notched gear and restrains the head plate in its non-play position when the slide member is in its non-actuated state but releases the head plate so as to allow the movement of the head plate between the non-play and play positions when the slide member has been actuated by the crank pin. A locking mechanism releasably locks the slide member in its actuated state, and a control member connected to the head plate is actuated by slidably contacting with the crank pin of the rotating notched gear so as to effect displacement of the head plate from the non-play position to the play position with a time lag after the slide member has been actuated by the crank pin and locked in its actuated state by the locking mechanism.
