Abstract: An optical disk apparatus includes a tray mounting an optical disk and a casing which stores the tray so that the tray may be inserted into and ejected from the casing. The tray has a guide rail on at least one of parallel sides relative to the direction of tray insertion or ejection and for guiding the movement of tray in the direction of tray insertion or ejection. The casing has rail guides formed on a side section of the casing in opposition with the guide rails when the tray is inserted and for guiding the guide rail, and a spring member formed on a frontend of the rail guides in the direction of tray insertion or ejection to provide elastic deformation when a force toward the tray insertion direction is applied to the spring member.

Abstract: A tray of an optical disk device and an optical disk device including the tray are provided. In a tray rear portion located at a higher level than a tray bottom portion, a first tapered surface as a draft taper and a second tapered surface sloping more gently than the first tapered surface are formed. An upper end of the second tapered surface is located farther from a center of rotation of an optical disk than a lower end, and thus air in a peripheral portion of the optical disk generated during rotation of the disk is introduced along the tapered surface to a rear.

Abstract: An optical disc device includes rails holding a tray so as to be put in and out with respect to a case and rail guides attached to a bottom chassis of the case to movably hold the rails, in which the rail guides have cross sections orthogonal to the running direction of the rails in a generally U shape and at least either one of the rail guides is formed with a projection in a part of the bottom surface abutting upon the rail. The projection is formed in an end range on the front face side of the case in the rail guide, and the rail rides on the projection of the rail guide when the tray is drawn out from the case.
