Abstract:
A disk player comprising:a disk conveying section having a loading roller driven by a driver; and a detecting section to detect control information of leading-in and ejection of one of a larger disk and a smaller disk by the disk conveying section, wherein said detecting section includes a first sensor which is positioned on or in a vicinity of a center line (X) of a disk conveying path so that an edge portion of the center hole of the disk or a boundary portion of a transparent portion and a reflection portion of an inner periphery of the disk is detected when the disk is conveyed by the disk conveying section, and is positioned between the loading roller and a disk insertion inlet so as to detect the larger disk only when the disk is loaded and positioned at a reproducing position, and wherein said first sensor detects a start timing of leading-in the disk when the disk is inserted, a disk size after the leading-in is completed, and a start timing of the re-leading-in the disk when the disk is pushed after ejection.
