The present invention proposes a double disc insertion preventing apparatus for a disc player with a simple construction while improving thinning. With a double disc insertion preventing apparatus for a disc player of the present invention, a roller supporter having a rotation axis is provided at a position in the vicinity of a disc insertion port of the supporter, a roller is supported with the ability to rotate freely at the rotating end located further back than the rotation axis of the supporter, the disc insert detection switch is attached on the circuit substrate placed furthermore back than the roller, an actuator is rotated by interlocking with the rotating operation of the roller supporter when the roller allows disc insertion causing a double disc insertion preventing signal to be sent by controlling the switch by the actuator, and wherein the rotation axis of the actuator conforms to the rotation axis of the roller supporter, and the actuator controls the switch at a position furthermore back over the roller.
