Optical Disk Transport Device for Optical Disk Player

Abstract

An optical disk transport device for optical disk player comprises a carrying roller, an optical disk guiding part located above the carrying roller, an elastic part for pressing the carrying roller towards the optical disk guiding part, and a motor for driving the carrying roller to rotate. The roll body of the carrying roller is of a bipyramidal structure with the diameter gradually decreasing from the two ends to the middle. The positions on the optical disk guiding part opposite to each pyramid of the carrying roller are provided with at least one rotatable driven roller. The rotating axes of each driven roller are located in the plane which is the rotating axis of the carrying roller located in and is vertical to the roof of the optical disk playing device, or are parallel to the plane. The ends adjacent to the middle of the carrying roller of each driven roller slant upwards, so as to make the driven rollers only contact the outer margin of the optical disk when the optical disk is inserted. The optical disk transport device can protect the front and back surfaces from being scratched during the process of transporting the optical disk. It is especially suitable for the optical disk playing device using the optical disks with the both surfaces being recording surfaces, and can implement the miniaturization of the optical disk playing device.
