Patent attributes
An optical disc drive apparatus includes a frame having a sidewall, and a disc tray supported by the frame. The frame has a supporting portion including a guide rib formed protruding from an inner wall surface of the sidewall and a plurality of guide protrusions formed protruding upward from the guide rib. The disc tray has a supported portion implemented by a guide groove slidably engaging to the plurality of guide protrusions. A guide protrusion positioned at the forefront among the plurality of guide protrusions is structured so as to come in surface-contact with a wall surface implementing the guide groove. With such a structure, an optical disc drive apparatus unlikely to be broken even if a force in a transversal direction is applied to the disc tray while the disc tray is at a disc-removable position can be obtained.
