ABSTRACT:
A lever device is provided between the magnetic tape head shift device for shifting the magnetic tape head and the capstan flywheel in a multitrack tape player. The lever device moves a specified first distance by energization of an operating device individually engaging, at both its ends, the magnetic tape head shift device and the capstan flywheel. The flywheel successively shifts the lever device a specified second distance and permits the head shift device to move until it selectively engages the flywheel by transferring the operation of a first process to the head shift device. The flywheel successively directly engages the head shift device, transferring operation of a second process. Thus, by the operation of the first and second processes, the head shift device shifts the magnetic tape head from a specific position to the next position.
