Abstract:
1. A tray guide mechanism for an optical disc drive that guides a backward and forward movement of a tray installed to slide into and out of a housing made of a lower case and an upper case, the tray guide mechanism comprising: guide rails, to slide into/out of both sides of the upper case, including outer sides to which rail covers, which slide into/out of the lower case while contacting the lower case, are fixed; a guide rail supporting unit installed at both sides of the lower case, to prevent the guide rails from deviating from a moving path; rail combiners formed at both sides of the tray in the moving path of the tray, and combined with the guide rails to slide into the guide rails; a forward moving distance limiting unit to limit a moving distance of the tray and the guide rails in a direction to which the tray and the guide rails project to prevent the tray from detaching from the housing; and vertical and horizontal restrainers protruding from the rail covers of the guide rails to prevent a vertical and horizontal movement of the tray inserted into the housing, wherein the guide rails are shaped such that the rail combiners are inserted thereinto, and include rails which slide into and out of the rail combiners while remaining in contact with the rail combiners.
