ABSTRACT:
A small-sized, multifunctioned micro cassette tape player has one motor and one solenoid and a drive plate connected to the solenoid for moving a head base and a pinch roller between engaged and retracted positions. The tape player has a cam mechanism which includes a cam plate having a stopper portion for engaging a control pin on the drive plate to hold the drive plate at an intermediate retracted position from the engaged position, when the solenoid is deenergized for the first time after being energized, for high speed cue, review, and erasure operations. The cam plate also has a displaceable guide portion for allowing the control pin to pass and the drive plate to return to the fully retracted position when the solenoid is again energized and deenergized.
