Abstract

A CD disc blocker and guide device is integrated into the escutcheon-lens assembly to prevent insertion of a CD disc between the CD player unit and the top cover to which it is attached. If such insertion is attempted, a guide surface on the device will deflect the disc into an appropriate path for successful CD disc loading. Also, this device prevents the accidental insertion of a CD disc into the player unit when another disc has been loaded therein. This invention accordingly prevents jamming and lodging of the discs in the CD unit or CD-AM/FM radio unit detracting from or preventing unit operation and further eliminates disc damage resulting from improper disc insertion.
