PURPOSE:To prevent exposing a disc to outdoor air to prevent dust sticking and damage of the disc, by storing the disc in a device body again if a specific instruction is not given within a preliminarily determined time after the time, when a disc takeing-out instruction is given, and the disc is not taken out. CONSTITUTION:When the taking-out instruction is given to a centralized control circuit 13 to make taking-out of a disc 2 possible, the centralized control circuit 13 allows a timer circuit 12 to start the time counting, and this counted value and the state of a leaf switch 10 are discriminated, and it is discriminated whether a specific instruction such as a repeat instruction or an insert instruction of the disc 2 is given or not; and if this specific instruction is not given till the counted value of the timer circuit 12 becomes a preliminarily determined valueafter the start of exposure of the disc 2 to outside air and the disc 2 is not taken out from a disc holder 3 and the leaf switch 10 is not opened, the control circuit 13 gives a control signal to a motor driving circuit 11. A loading motor 4 is rotated counterclockwise and is moved, and the disc holder 3 is set to a device body 1, and the disc 2 is stored. |
