Abstract: Disclosed is a housing device for compact disks. The housing device includes stackable and bookbindable CD trays, each of which has clip pegs with a hole defined at a center portion of each CD tray. A compact disc can be released by pushing a non-data portion thereof through a release opening defined adjoining the hole in each CD tray. An adhesive tape can be affixed to one side ends of the CD trays and a lock band can be attached to the other side ends of the CD trays, to bookbind the CD trays together.

Abstract: Disclosed is a CD case. The CD case has a CD holder plate for carrying a compact disc, and a sleeve jacket. The CD holder plate has a body and a title bar which is integrally formed with a proximal end of the body. A distal end of the body of the CD holder plate possesses an upward curved edge portion so that the CD holder plate can be easily slid into the sleeve jacket. The CD holder plate is formed with a circular liner ridge. A bole is defined at a center of the CD holder plate inward of the circular liner ridge. Three spring brakes arc formed on an inner edge of the CD holder plate which inner edge defines the hole, in a manner such that they are spaced apart one from another in a circumferential direction. Clip pegs are respectively formed on free ends of the spring brakes to grasp the compact disc. Three guide pieces are formed on the inner edge of the CD holder plate which inner edge defines the hole, in a manner such that they are respectively opposed to the three spring brakes.
