Claim:
A case for accommodating a disc shaped recording medium comprising: a front lid provided to be opened and closed so that the disc shaped recording medium is put in and taken out through a front side of the case, a holder provided for detachably attaching the disc shaped recording medium to a bottom of the body, the holder including a central button, and three pairs of legs each disposed at opposite sides of one of three imaginary lines radially extending at equal angles about an imaginary center of the button, each leg having one of two ends connected to a seat formed integrally with the bottom of the body by a first hinge disposed on a line perpendicular to the corresponding imaginary line, each leg having the other end formed with a thin second hinge for connecting each leg to a sidewall of the button, three annular pieces each formed integrally with a pair of legs and with an engagement groove for engaging a fixing hole of the disc shaped recording medium with the legs, each annular piece being disposed around the button, a spring portion formed integrally with each pair of legs so as to correspond to the underside of the disc shaped recording medium, wherein the fixing hole of the disc shaped recording medium is inserted onto the annular pieces causing the disc shaped recording medium to be fixed thereto, the disc shaped recording medium is released when the button to which the disc shaped recording medium is fixed is pressed, the disc shaped recording medium initially moves downwardly with the button, further downward movement of the button causes the springs to engage the underside of the disc shaped recording medium, thus restraining the disc shaped recording medium from further downward movement, the annular pieces pass downwardly through the fixing hole of the restrained disc shaped recording medium and the disc shaped recording medium is released.
