点がある。 That is, in order to keep the shutter member 4, which moves in parallel along the rail 9 formed in the case 12, in a closed state when the magnetic disk 2 is not in use, one end is connected to the case 12 and the other end is connected to the shutter member 4. A tension coil spring 5 is used which draws the shutter member 4 against the stopper 7 and keeps the shutter member 4 in the closed position. Here, the tension coil spring 5 expands and contracts by the stroke of the shutter member 4, and since a sufficient length is required, it is bent at a right angle via a roller 6. Therefore, the structure is complicated and has a wide area, and when the shutter member 4 is opened, the tension coil spring 5, which is stretched as shown in FIG. 2, approaches the disk 2 with the disk hub 3 near the window 8. There is a drawback that it does.

い。 An embodiment of the present invention will be described below with reference to FIG. FIG. 3a is a plan cross-sectional view of this embodiment, and FIG. 3b is a cross-sectional view taken along the line AA. The opening/closing mechanism of the dustproof shutter of the present invention includes a shutter member 4, a rail 9 and a stopper 7 for regulating the movement of the shutter member 4, one end of which is attached to a side 4a of the shutter member 4, and the other end of which is attached to a corner 11 of a case 12. It consists of a torsion spring 10 which is connected to the shutter member 4 and pushes the shutter member 4 in the closing direction. In this embodiment, the rail 9 is arranged linearly along the edge of the case 12, and the shutter member 4 moves along this rail 9 parallel to the edge of the case 12.
The case 12 has windows 8 on the top and bottom surfaces, respectively.
is formed. The shutter member 4 is composed of shutter portions 4b that respectively close the windows 8 formed on both sides, and coupling portions 4c that connect the shutter portions 4b on both sides. When the shutter member 4 is in the closed state, the shutter member 4 is pressed against the stopper 7 by the torsion spring 10. When the shutter member 4 shifts to the open state, the shutter member 4 moves in parallel along the rail 9, and the coil portion 10a of the torsion spring 10 moves in the corner area of the case 2 accordingly. Furthermore, the shutter member 4 is
It moves toward the corner area where the torsion spring 10 is arranged and covers the corner area. Therefore, the corner area of the case 12 is effectively utilized. Furthermore, even when the window 8 is open, the torsion spring 10 is housed inside the corner area of the case 12. During this operation, the torsion spring 10 deforms as shown in FIG. 4 and is no closer to the disk 2 than the position of the torsion spring 10 shown in FIG. 3a when the shutter member 4 is closed.

有効に利用できる。 As described above, according to the present invention, the roller is not required, the structure of the spring part is simplified, the area occupied can be reduced, and the spring material is also prevented from coming close to the disk when the window is opened. In addition, since the torsion spring is placed in the corner area that is in the direction covered by the shutter member when the window is opened, the corner area that is not covered by the movement of the shutter member (Fig. 1a)
(the corner area where the roller 6 is attached) can be effectively utilized.
