ABSTRACT:
This invention relates to a single touch drawer type opening and closing device for a compact disc storage case in which a disc storage drawer is automatically locked during closing and automatically opened when released by the single touch. Also, an opened drawer plate will not be removable from the case. A lock contains a key guiding device which operates in one direction. A drawer plate has a key, a stepped sill, and disc storage space. The drawer plate is inserted into a storage case. A hooking protrusion is located on the storage case. A triangular plate is mounted within the lock to form a key guiding way. A hooking device, formed with a protuberance, is pivotably fixed by a pivot pin. A slide, movably fixed with second hooking devices, is urged by a compression spring. A five sided flat plate key, formed with locking protuberances, is mounted on the drawer. In another embodiment, a rail groove is formed with several steps as a one way direction path. A leaf spring is fixed on the case. A bracket type key is pivotably fixed on the drawer by a pivot pin 18 to thereby be urged by the leaf spring.
