Abstract
A disc apparatus which can easily perform emergency-ejection operation by using two motors in a cartridge retraction device and a disc loading device. The disc apparatus includes two clutches provided in the middle of gear trains of the two motors which actuate the cartridge retraction device and the disc loading device, respectively, an emergency ejection-operating lever for switching both of the clutches from an engaged to a disengaged state, and an ejecting spring for ejecting a cartridge when both of the clutches are switched from the engaged to the disengaged state.
Claims6
