FIG. 3 is a plan view of the upper case in FIG. 2, seen from the disk side, showing the shutter closed state. FIG. 4 is a plan view from FIG. 3 with the shutter in an open state. FIG. 5 is a plan view of the lower case in FIG. 2, seen from the disk side, showing the shutter closed state. FIG. 6 is a plan view from FIG. 5 with the shutter in an open state. FIG. 7 is an exploded perspective view of the lower case shown in FIG. 5 with each component separated. FIG. 8 is a side view of FIG. 1 seen from the F side.
FIG. 9 is a sectional view taken along line AA in FIG. 1. FIG. 10 is a BB sectional view in FIG. 1. FIG. 11 is a CC sectional view in FIG. 5. FIG. 12 is a side view showing the main assembly method after the subassembly of the upper case, disk, and lower case is completed. FIGS. 13a and 13b are diagrams for explaining the reason why the pair of shutters in the present invention are arranged separately in the upper and lower cases, and are plan views showing an example in which the pair of shutters are arranged in either of the upper and lower cases. FIGS. 14 and 15 are external perspective views of a conventional disk cassette. 1... Upper case, 2... Lower case, 3... Cassette housing, 5... Opening, 7... Shutter, 1

Claims

[Scope of utility model registration request]

A disc-shaped recording medium, a cassette housing divided into upper and lower halves for storing the disc-shaped recording medium, an opening formed in the cassette housing, and a pair of cassettes that divide the opening into approximately two parts and can be rotated to open and close on both sides. Shutter,
In the disc cassette, the shutter holder includes a shutter holder that holds the shutter between the shutter and the cassette housing, and a shutter spring that biases the shutter so that the shutter closes the opening. What is claimed is: 1. A disk cassette, which is guided and held in a gap between the inner surface of the case and a shutter holder, and has a shutter rotation center and a shutter spring disposed within the gap.
