Disc apparatus

A disc apparatus in which a disc inserted by automatic loading by a plurality of arms supporting outer peripheral edges of two kinds of discs with different diameters so that said disc can be loaded into said disc apparatus is loaded into the inside of said disc apparatus or a disc accommodated within said disc apparatus is unloaded from said disc apparatus to the outside, comprising:

• an elevation frame for swinging a turntable on which said disc is fixed and rotated in the upper and lower direction, in which a rotary base plate of a disc supporting arm is slightly distorted in the initial state in which said elevation frame is lowered, whereby a tip end of a holder provided at a tip end of said disc supporting arm approaches or contacts the surface of said elevation frame to prevent a rear end side of a large-diameter disc or a small-diameter disc from entering the lower surface of said holder.
