Abstract: To make it possible to keep a disk-like recording medium accommodated in a case under a stable state without shaking and to easily take it out, a receiving table on which a center portion of a disk is put is so formed at a base center of a main body as to protrude from a base surface. An outer peripheral edge for supporting thereon a disk outer periphery protrudes from the receiving table as a center. A removal member for supporting the outer periphery of the disk and engaging with the outer periphery is disposed by cutting off a part of the outer peripheral edge. The removable member includes a lift portion for supporting thereon the disk outer periphery, formed inside a rocking lever and a button formed outside the lever. Hooks for engaging with the disk outer periphery are provided to the lever.

Abstract: To change a case with easy operation from a sale case state engaging with a recording medium to a rental case state accommodating the recording medium in an inner case protruded from a case ceiling side as to be capable of being nipped out, recording medium accommodation means is so constituted as to fix and hold the recording medium to a recording medium engagement member, and the inner case accommodation means accommodating the recording medium is constituted in such a manner as to open and release the recording medium engagement member from a base body, to engage the recording medium engagement means with a ceiling member loosely fitted to a cover of the case, to move the ceiling member loosely fitted to the ceiling side of the cover along a groove of the cover and to fit it loosely near to the bottom surface of the cover and to accommodate the inner case accommodating the recording medium from the ceiling portion so released into the case.

Abstract: To make it possible to keep a recording medium for rental or sale use accommodated in a cover case under a stable state without shaking and to take it out without applying excessive force, a receiving table having a support surface on which a center portion of the disk-like recording medium is put is so formed at a base center of a main body as to protrude from a base. Two slit grooves are formed at the center of the support surface of the receiving table with a predetermined gap between them. Engagement protuberances protrude from distal ends of arms formed between both slit grooves in such a fashion as to protrude from the arms and to form a pair. An outer peripheral edge extends from the base surface with the receiving table as the center and the engagement protuberances fit into a center hole of the disk. The outer periphery of the disk is put on and supported by the outer peripheral edge.
