ABSTRACT:
The tape drive unit of the present invention is constructed such that the reverse rotation of a motor (16) causes a mode cam (32) to drive for setting any mode of normal play, reverse play, fast forward and rewinding, and thereafter the forward rotation of the motor (16) causes a reel shaft (3) or a reel shaft (4) to rotationally drive according to said mode and a head base (51) is slid upon FWD/REV to set up a magnetic head and pinch rollers. With such construction, each operation of normal play, reverse play, fast forward and rewinding can be performed without using a plunger or microcomputer, thereby eliminating the fear of troubles due to the plunger malfunction or a microcomputer bug.
