A disc device can easily install an eject/lock mechanism of self-hold solenoid type into a narrow space inside it, and by omitting some mechanisms of the structures, the cost can be lowered, and the malfunction frequency is therefore reduced. The disc device operates the eject/lock mechanism and opens a disc-loading unit by adding a pulse current to the self-hold solenoid. The eject/lock mechanism has a releasing spring, and when closing the disc-loading unit, a resilient force is generated by the releasing spring, and when opening the disc-loading unit, the resilient force is released. An activating end of the releasing spring is connected to a moveable plate of the self-hold solenoid.
