Claims

[Scope of utility model registration request]

A plurality of disc storage cases containing discs are stored in a case constituting the disc storage section in a manner that can be freely taken out, and a disc storage case containing a predetermined disc is searched for and taken out from among these disc storage cases. In the disc ejecting device, the disc ejecting unit is provided with a disc ejecting unit, in which the detecting unit is formed in the housing by arranging a plurality of detection pieces in a comb-like shape corresponding to storage positions of the disc storage case, and the disc ejecting unit is configured to eject the disc. A pair of sensors that move along the detection section and output a detection signal corresponding to each detection piece are installed at a distance from each other in the direction of movement, and the detection signal of one of these sensors is used to detect the detection piece. The disc ejecting device counts and searches for a detection piece corresponding to a predetermined disc storage case, and controls the positioning of the disc ejecting part to a position facing the predetermined disc storage case based on detection signals from both sensors.
