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

摘要

A case for accommodating a disc-shaped recording medium such as CD or DVD is disclosed. The case included a front lid opened and closed and a body formed with a central button and a holder including an annular piece formed with an engagement groove for engaging a fixing hole of the disc-shaped recording medium with legs. The annular piece is disposed around the button and the holder further includes a spring portion. A force acting so that an upper side of the disc-shaped recording medium is pressed such that the recording medium is depressed and rendered against a force acting so that the button is pushed upward via a second hinge by the spring portion. As a result, the button is prevented from being pushed over its toggle dead point and the disc-shaped recording medium is re-fixed to the annular piece by reduction and/or elimination of the external force.
