A disc identifying device has sliders moving relatively in a direction such that a gap therebetween widens, one sensing switch switching-operated when a large diameter disc or a small diameter disc is inserted, the other sensing switch switching-operated only when the large diameter disc is inserted, and an actuating plate permitting the slider to move from an the initial position via a first position corresponding to the sensing switch to a second position corresponding to the sensing switch only when the large diameter disc is inserted. One end portion of the actuating plate has a stopper portion for preventing the slider from moving to the second position. The other end portion thereof is engaged with the slider. |
