Abstract
An optical disk case assembly comprises A-side and B-side case parts (10,11). Each case part has a central opening (28) and a radially extending window (29). Metal shutters (12) and (17) are mounted for sliding movement on the case parts (10,11). A slide member (13) made from a plastics material is slidably mounted on the case part (10) and held in position by shutter (12). A slide member made from a plastics material is also mounted on the case part (11) and held in position by shutter (17). The slide member on the case part (11) engages the slide member (13) so that the two slide members together with shutters (12 and 17) move together. The slide member (13) has an operating tab (72) which engages a projection in a cartridge compartment so that the shutters (12 and 17) are caused to open during insertion of the case assembly into such a compartment). The case part (10) is also provided with a locking lever (15). The components associated respectively with the case parts (10,11) may be secured in position prior to inserting an optical disk. Consequently, in order to insert an optical disk, it is only necessary to place the optical disk in position and secure the two case parts (10,11) together with self-tapping screws (39).
