PURPOSE:To improve the vibration resistance by moving a disc positioned to a prescribed position on a disc holder to the playing position while it is clipped by the positioning member. CONSTITUTION:The disc is loaded from a slot and also engages with pin members 54f, 55f provided to positioning members 61, 62 and is progressed while pushing aside both the positioning members 61, 62 to the left and right. When the turning center of the disc 5 exceeds a line tying the axial center of the left and right pin members 54f, 55f, since both the pin members 54f, 55f are energized in the direction that they approach the disc outer circumference, the disc 5 is retracted into the housing 2 while it is detached from the hand. A guide member 91 guides effectively the disc and the disc is positioned to a prescribed position on the container 22. Since the disc is positioned while it is clipped with the four pin members 54f, 55f, 57h, 58h, the disc is not affected by external vibration such as shock of cabin.
