Abstract

A disc player performs disc loading and ejecting while closing and opening the player lid. The disc player includes a housing having a first guide groove longitudinally formed on an inner side thereof, a deck including a turntable, a moving plate mounted over deck to horizontally move in frontward and rearward directions, a disc tray engaged with the moving plate and for loading and ejecting a disc onto and out of the turntable while vertically moving down and up in response to rearward and frontward movements of the moving plate, a lid engaged with the housing to pivotally close and open, and movement mechanism for controlling the frontward and rearward movements of the moving plate when the lid closes and opens. A simple structure and miniaturization of a disc player can be accomplished since disc loading and ejecting is performed without using a motor and gears.
