PROBLEM TO BE SOLVED: To provide an optical disk door device of high reliability with no change in the lapse of time which automatically closes dustproof doors after an optical disk is inserted and is discharged. SOLUTION: The dustproof doors 2, which are capable of opening/closing the optical disk insertion port 1a, are elastically energized in the close-moving direction and are simultaneously made to be open-movable against elasticity by being abutted on the outer peripheral part 11a of the inserted optical disk 11. Then, a lever 4, which transmits the optical disk discharging action of an optical disk reproduction mechanism 6 to the dustproof doors 2 for open- movement, is provided. The optical disk 11, when inserted or discharged, passes while being held between the dustpoof doors 2 due to an elastically energizing force, but scratches are not generated because the outer peripheral part 11a of the optical disk 11 is abutted on the dustproof doors 2 and are not in contact with flat surface parts. The dustproof doors 2 can be closed without causing scratched to the optical disk 11 after the optical disk 11 is inserted and is discharged, thus the dustproof doors 2 of high reliability with no change in the lapse of time are obtained.
