Abstract

PURPOSE:To prevent a trouble from occurring due to the deformation of a shutter by providing a groove to guide a projection on the end face of a shell, and abutting the projection on the terminating plane of the groove. CONSTITUTION:The shutter 2 is formed in U-shape consisting of a front plate 21, a rear plate 22, and an end face plate 23 which connects them, and the projection 24 facing inside provided on the front plate 21 is fitted in the groove 13 of the shell 1, and also, the projection 4 facing inside provided on the end face plate 23 is fitted in the groove 5 of the end face of the shell 1. Also, a spring 3 which presses the shutter is mounted by connecting one terminal of it to the projection 4, and the other terminal to the shell 1. Then, by constituting the device so that the projection 4 can abutted on the terminal plane 51 of the groove 5 when the shutter 2 is set at a closed position, the shutter 2 can be surely prevented from coming off a recessed part 12. Thereby, it is not feared that the shutter 2 rides across the recessed part, and no trouble occurs due to the deformation of the shutter 2.

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a disk power set in which a storage disk such as a floppy disk is externally driven to rotate and record/reproduce data while the storage disk is housed therein. This invention relates to improvements in a shutter section that opens and closes an opening of a cassette.

(Prior art and its problems) As shown in the front view in FIG. 4, a disk cassette stores a disk 10 in a shell 1 having an opening 11 for inserting a recording/reproducing head, and a ,
A shutter 2 that opens and closes the head insertion opening 11 is attached.

However, since the plastic shutter is more easily deformed than the metal shutter, the shutter 2 biased by the spring 3 sometimes comes off from the recess 12 and rides on the thick part 14 of the shell 1.

(Measures Pi for Solving the Problems) The present invention improves the above-mentioned drawbacks, and ensures that the shutter 2 does not come off the recess 12 of the shell 1 and stops at a predetermined closed position. .

以下本発明を図面を参照して詳しく説明する。The present invention will be explained in detail below with reference to the drawings.

The shutter 2 has a U-shaped cross section consisting of a front plate 21, a rear plate 22, and an end plate 23 connecting the two, and an inward protrusion 24 provided on the front plate 21 fits into a groove 13 of the shell 1. Also, the inward protrusion 4 provided on the end plate 23 fits into the edge 5 of the end face of the shell l. Then, a spring 3 for biasing the shutter is attached by locking one end to the protrusion 4 and locking the other end into the shell 1.
