Abstract
An auto-ejector incorporated in a disk recording and/or reproducing apparatus is driven by a disk driving motor and a head driving motor which are requisite for the apparatus. That is, the ejector is triggered under the power of the head driving motor, and a disk cartridge in which a disk is accommodated is ejected under the power of the disk driving motor. Thus, any device, such as an electromagnetic device, a motor or the like used only for the ejector is not needed.
