Abstract

An optical disc device is disclosed. In the optical disc device, a cam portion configured to include a holder that is supported on the outside of a cam member to turn and move vertically is provided in a position that is in vicinity of a tray being supported by elevator cam gears. In disc loading/ejecting operations, the cam portion is turned and a projecting portion pushes down a tray projecting portion of the tray, so that a space S if formed between the tray and the disc. Since the tray is shaped into a closed circular tray, a rigidity of the tray can be ensured and also the space used to avoid a contact between a projecting portion on a lower face of the disc and a surface of the tray can be provided by bending the tray.
