Abstract: An ejectable disc case is made up of three pieces—a bottom piece, a top piece, and a movable tray, all of which can formed by injection molding and then assembled together by snap fit. The bottom has a hole through which a disc can be ejected and two bottom grooves engaged by groove mechanisms of the tray. The tray has a disc perimeter support for supporting a perimeter of the disc in the tray in the retracted position, a disc locking mechanism for holding the perimeter of the disc in the tray in the retracted position, a center disc rest connected to the disc perimeter support by a center disc rest slant ramp, and a hook with a hook prong that extends upwardly from the center disc rest. The hook prong moves upwardly through the disc hole and engages the disc center to secure the disc center when the tray moves from the extended position to the retracted position but disengages the disc and moves downwardly through the disc hole when the tray moves from the retracted position to the extended position.

Abstract: Disclosed herein is an insertion type compact disc case which is designed to simultaneously push forward opposite sides of a rear periphery of a disc, received in a case body, thereby securing safe and accurate discharge of the disc. The disc case comprises a case body internally defining a square receiving space, into and from which a circular compact disc is inserted and discharged through an opening formed at a front surface thereof, a pair of elongated slits laterally formed at a rear surface of the case body, and a pair of discharge operating cam plates symmetrically arranged at both lateral positions in a rear region of the receiving space in correspondence to both the elongated slits so that they are laterally movable along guide units. Rear portions of the discharge operating cam plates protrude outward beyond the elongated slits so as to be exposed to the outside, respectively.
