SOLUTION: A roller 11 disposed at the front end of an arm 10 for housing the optical disk 100 comprises a stationary reference roller 11a and a movable roller 11b which is freely movable in the thickness direction of the optical disk 100. The movable roller 11b is energized by a leaf spring 20 toward the reference roller 11a. When the optical disk 100 is inserted, the movable roller 11b moves in the thickness direction according to the thickness of the optical disk 100 and the optical disk is grasped from above and below by the reference roller 11a and the movable roller 11b.
