Claims

[Claims for Utility Model Registration] A disc insertion slot into which an optical disc is inserted in a direction along the disc surface; a chucking device provided on the inner side of the disc insertion slot for holding the optical disc; a disk transfer device that is provided between the disk insertion port and the chucking device and that transfers the optical disk inserted from the disk insertion port to the chucking device; a sensor device for detecting the presence or absence of the optical disk at at least one position corresponding to the outer circumference of the optical disk held by the chucking device; and a control device for driving and controlling the transfer device, and the control device controls the optical disk when the sensor device detects the presence of the optical disk when the chucking device is not holding the optical disk. Drive-controlling the disk transfer device so as to transfer the disk in a direction toward the chucking device, and when the presence of the optical disk is not detected by the sensor device and a signal instructing ejection of the optical disk is supplied; . A disk player comprising driving and controlling the disk transfer device in a direction to eject the optical disk from the disk insertion port.
