Abstract
In a drive mechanism for a cassette tape recording/reproducing apparatus comprising a head base movable among the stop, pause and playback positions, a pair of capstans, and a pair of pinch rollers, a pair of assist gears adapted to be driven by the capstans and a pair of plungers are provided. When the first plunger is actuated to allow the first assist gear to rotate through its engagement with the forward capstan, selector means mounted on the head base is moved to the position engageable with the forward pinch roller and the head base is advanced to the pause position with the aid of the first assist gear. When the second plunger is further actuated, the head base is advanced to the playback position and the forward pinch roller is brought in contact with the forward pinch roller. The reverse operation can be done by actuating first the second plunger and then the first plunger.
