Case for disc-shaped recording medium with function of preventing dropout of holder

摘要

A case for accommodating a disc-shaped recording medium (a) such as CD or DVD is disclosed. The case includes a front lid (20) opened and closed and a body (1) formed with a central button (10) and a holder (5) including an annular piece (13) formed with an engagement groove (15) for engaging a fixing hole (b) of the disc-shapedrecordingmedium (a) with legs (7). Theannularpiece (13) is disposed around the button (10) and the holder (5) further includes a spring portion (9). A force acting so that an upper side of the disc-shaped recording medium (a) is pressed such that the recording medium (a) is sunk is rendered competitive against a force acting so that the button (10) is pushed upward via a second hinge (8) by the spring portion (9). As a result, the button (10) is prevented from being pushed over its toggle dead point and so that the disc-shaped recording medium (a) is re-fixed to the annular piece (13) by reduction and extinction of the external force. <IMAGE>
