Abstract:
1. A disc identifying device comprising: a first slider and a second slider moving relatively in a direction such that a gap between the first and second sliders widens when a disc having a diameter equal to or larger than a first diameter is inserted to the identifying device; a protruding portion pressed by an end of an inserted disc and provided on each sliders; a first sensing switch operated when the disc is inserted into the identifying device; a second sensing switch operated only when a disc having an diameter equal to or larger than a second diameter that is larger than the first diameter is inserted into the identifying device; an actuating plate permitting the first slider to move from an initial position via a first position at which the first sensing switch is performed to a second position at which the second sensing switch is performed with the protruding portion of the first slider pressed by a disc only when the disc having a diameter equal to or larger than the second diameter is inserted into the insert slot, wherein: one end portion of the actuating plate has a stopper portion for preventing the first slider from moving to the second position and the other end portion thereof is engaged with the second slider; and when the second slider moves to a predetermined position due to the pressing to the protruding portion by the disc, the actuating plate moving cooperatively with the second slider is moved from a movement path of the first slider to a release position at which the first slider is permitted to move to the second position of the first slider because the stopper portion is removed.
