Abstract
A tray unit is moved into a housing or partially pulled out from the housing by a horizontal motor provided in the housing. Since the tray unit can load a plurality of cassettes, the weight of the unit is largely changed in accordance with the number of loaded cassettes. The horizontal motor must be controlled by accurately detecting the moving position of the tray unit. The rotation of the horizontal motor is transmitted to a rotary member. The rotation of the rotary member is associated with a pulse detecting element provided on a printed circuit board for tray position detection. The moving position of the tray unit is detected by counting pulses obtained from the pulse detecting element in accordance with the rotation of the rotary member.
