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 .
