Abstract
An automatic reverse cassette tape recorder, whose central part acts as a rotation center, and both ends of which are each provided with a magnetic head, and wherein the head-supporting board is rotated by a plunger actuated at the detection of a tape end and as often as required. Both magnetic heads are alternately pushed by the rotation of the head-supporting board. The operation mode of a motor polarity changeover switch is shifted in accordance with the rotation of the head-supporting board. A forward-reverse rotation concurrent motor has its rotation reversed to effect an automatic reverse tape run when the operation mode of the motor polarity changeover switch is shifted.
Claims11
An automatic reverse cassette tape recorder which comprises:
- a rotatable head-supporting board whose central part acts as a rotation center for the board and both ends of which are each provided with a magnetic head;
- a plunger mechanism including a plunger operable selectively manually and upon detection of a tape end;
- coupling means disposed between the plunger and the head-supporting board to connect the plunger and board together, and operable to push both magnetic heads alternately by rotating the head-supporting board in accordance with the reciprocation of the plunger;
- and
- motor polarity changeover switching means electrically connected to a forward-reverse concurrent motor, and whose operation is shifted from one mode to another upon rotation of the head-supporting board, thereby reversing the rotation of the motor.
