性片である。Figures 1 to 3 show an embodiment in which the present invention is applied to a micro floppy disk cassette. Figure 1 is an exploded perspective view of the cassette with the upper half and upper liner sheet removed. Figure 2 is an enlarged sectional view of the main part to explain the state in which the liner is pressed against the magnetic disk by the sheet-like elastic piece of the elastic sheet, and Figure 3 is an enlarged sectional view of the main part of the liner and the sheet-like elastic piece. FIG. 2 is a cross-sectional view taken along the line III-III in FIG. 2 for explaining the contact state. Figures 4 to 6 show conventional bowls for micro floppy disk cassettes. Figure 4 is an exploded perspective view of the entire cassette, and Figure 5 is a sheet-like elastic piece. FIG. 6 is an enlarged sectional view of the main part to explain the state in which the liner sheet is pressed against the magnetic disk, and FIG. It is a sectional view taken along the line shown in FIG.

Claims

[Scope of utility model registration request]

a sheet-like recording medium housed in a cassette case; a liner sheet interposed between at least one surface of the sheet-like recording medium and an inner surface of the cassette case opposite to the one surface; In the sheet-like recording medium force set, each of which includes a sheet-like elastic piece that elastically presses the liner sheet against the sheet-like recording medium, an interposition is provided between the liner sheet and the inner surface of the cassette case. The sheet-shaped elastic piece is provided with a sufficiently large elastic sheet and a cut-and-raised portion partially formed in the elastic sheet, and the sheet-shaped elastic piece is provided with a cut-and-raised portion that is partially formed in the elastic sheet. A sheet-like recording medium force set characterized by comprising an elastic piece.
