Disk loading/unloading apparatus for compact disks of different diameters

A disk loading/unloading apparatus for a disk player, comprising

• a loader holder;
• a loader supported for movement between an unloading position and a loading position in said loader holder and having a loading/ejecting opening and a disk insertion plane extending therein from the opening such that a disk is allowed to be inserted into said loader along the disk insertion plane from the opening,
• said loader including detecting means for detecting an outside diameter of a disk as the disk is inserted into said loader in the unloading position through the opening, said detecting means having a moving member adapted to be pressed by an outer peripheral edge of the inserted disk and be moved in a direction intersecting the direction of insertion of the disk within the disk insertion plane as the disk is inserted into said loader;
• and
• trigger means for pushing said loader in the unloading position toward the loading position along with the inserted disk when the insertion portion of the inserted disk exceeds a trigger distance determined in accordance with the outer diameter of the inserted disk, the inserted disk having the remainder portion kept projecting from the loading/ejecting opening of said loader when said loader is pushed,
• said trigger means including a conversion member arranged on said loader, the conversion member converting the disk insertion operation into a loader pushing operation in cooperation with said loader holder and changing means for changing a beginning time for the loader pushing operation of the conversion member in accordance with a distance of movement of the moving member.
