PURPOSE:To enlarge the minute movement of a holder by means of a detection lever so as to quickly and surely confirm the operation of automatic loading and automatic unloading, by causing one end of the detection lever which is engaged with a projecting pin installed to the holder to come into contact with a detection switch. CONSTITUTION:When a disk 2 is inserted from an inserting port 3, the disk 3 is brought into contacted with a prescribed position of a holder 1 and projecting pins 5 and 6 installed to the holder 1 are also moved in the direction A. Then a detection lever 22 brought into contact with the projecting pin 5 is turned by the forcing force of a tension spring 24. When the detection lever 22 turns, the lever 22 pushes a detection switch 25. As a result, the detection switch 25 is turned on and a drive motor 21 is actuated. Accordingly, drive levers 16a and 16b are turned and the automatic loading of a disk 2 is started. When the automatic loading is started, movable plates 19a and 19b are moved forward (direction A) and the disk 2 is mounted on a prescribed location.
