Patent ID: 7890965

Claim:
A disk carrying device for use with a small diameter disk or a large diameter disk, the disk carrying device comprising: a pair of detection arms; and a switching arm linked with either of the pair of detection arms and provided with a first cam hole on one end, a second cam hole on an other end, and a protruded part; wherein the first cam hole is provided with a space for allowing movement of a shaft of one of the pair of detection arms when the small diameter disk is inserted so that the switching arm is not moved due to movement of the shaft of the detection arm, and the first cam hole is formed so that, when the large diameter disk is inserted, the switching arm is moved by movement of the shaft through the first cam hole; wherein the second cam hole is structured to move a rotary axis of a disk end detection lever for detecting a state of a large diameter disk which is inserted and carried to a predetermined position so that the rotary axis of the disk end detection lever is capable of being moved from a first engagement part in a frame to a second engagement part and, when the large diameter disk is inserted again without taking out after the large diameter disk has been ejected, the rotary axis is guided along a slant face so that the rotary axis is engaged with the second engagement part; wherein the protruded part of the switching arm moves a guide lever at a time of insertion of the large diameter disk so that a stopper part for positioning the small diameter disk is retreated from a disk playing space and, when the large diameter disk is inserted again without taking out after the large diameter disk has been ejected, the stopper part for positioning the small diameter disk is maintained in a retreated state from the disk playing space.
