Abstract
A tape recorder comprises a control motor disposed separately of a tape driving motor and controlled by a control switch; a cam shaft to which the driving force of the control motor is transmitted; a head support plate for supporting a magnetic head, and a pinch roller or the like and which is movable between a first position in which the magnetic head is in contact with the magnetic tape and the tape is clamped between the pinch roller and the capstan shaft and a second position in which the magnetic head is not in contact with the tape and the tape is not clamped between the pinch roller and the capstan shaft; a biasing member for biasing the head support plate toward the first position; and a press cam secured to the cam shaft and to which a support plate is biased by the biasing force of the biasing member. The press cam, by its unitary rotation with the cam shaft, controls the position of the head support plate against the biasing force of the biasing member. The tape recorder further comprises a control cam secured to the cam shaft and coupled to the control switch to change over the control switch by unitary rotary rotation with the cam shaft and the press cam.
