Abstract
In a disk carrying device including a first idle gear rotatably supported by a lower chassis and a second idle gear for contacting and separating from the first idle gear to perform a rotation operation, the second idle gear and a roller gear meshing therewith are rotatably supported by a feed plate to cause the second idle gear to contact and separate, from below, from the first idle gear rotatably supported by the lower chassis. Because of this configuration, in disk insertion, a downward force F1 acts on the second idle gear and a pushing pressure of the feed roller to a disk D decreases. In disk ejection, an upward force F2 acts on the second idle gear and the pushing pressure of the feed roller to the disk D increases.
