DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage disk device, and prevents a case body containing a storage disk medium from being erroneously inserted into a storage position when the case body is erroneously inserted into a storage position in front and back and in a front-rear direction. More specifically, the present invention relates to a storage disk device which enables braking by sliding to the bottom surface of a case body when performing the operation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a case 2 in which a floppy disk, which is a storage disk medium, is rotatably housed.
FIG. 9 is a plan view showing a state where the card is correctly inserted when the card is inserted into the storage position via the “0”. FIG. 2 is a plan view showing a state in which the case body is inserted into the opening 20 with the front and back wrong. Here, in the embodiments described below, a case of a floppy disk will be described. However, the present invention is not limited to this, and it is needless to say that the present invention can be applied to a case body containing a magnetic tape or a magneto-optical disk.

In FIGS. 1 and 2, for example, a case body 2 prepared as a resin molded product is formed continuously from an insertion side wall 2a serving as a leading surface when the case body 2 is inserted in the direction of arrow D shown in the figure. The case body 2 is formed with a chamfered portion 2b, a discharge side wall 2c serving as a leading surface when discharged, and a bottom surface serving as a sliding contact surface for performing a later-described braking when further discharged.

When the case body 2 is stored, a recording / reproducing means (not shown) performs a predetermined recording / reproducing on a recording medium.

The opening 20 is provided in the base 1, while an erroneous entry prevention mechanism is provided in the lower right corner of the opening 20, so that erroneous insertion of the case body 2 is performed in the state shown in FIG. When discharging to the outside, braking is performed by sliding against the bottom surface of the case body 2 with a predetermined pressure, so that excessive discharging can be prevented.

For this purpose, the erroneous insertion prevention mechanism comprises a shaft 5 shown in broken lines, which is implanted from the base 1 near the opening 20 toward the back side of the paper surface of FIG. The operating member 3 is supported so as to be rotatable and can be tilted with respect to the center axis of the shaft body 5 as described later.
Is provided. The operating member 3 is moved to the operating position shown in FIG. 1 by the tensile force of a tension coil spring 6 (shown by a broken line) stretched between the hook portion 1a of the base 1 and the operating member 3 and then moved to the operating position shown in FIG. It is configured to return to the illustrated standby position.

An engaging portion 4 is fixed to an end of the operating member 3 so as to project toward the front of the drawing, and the case body 2 is correctly inserted from the opening 20 as shown in FIG. In some cases, the engaging member 4 comes into contact with the chamfered portion 2b of the case body, so that the operating member 3 resists the tensile force of the tension coil spring 6.
Is configured to generate a component force to rotate the shaft around the shaft body 3 in the direction of arrow D1. On the other hand, this locking part 4 is
When the case body 2 is inserted upside down as shown in FIG. 2, the case body 2 comes into direct contact with the insertion side wall 2a to prevent further entry of the case body, thereby preventing erroneous insertion.

As described above, the case 2 can be inserted from only one direction.

FIG. 3 is a sectional view taken along line XX of FIG. 2, and FIG. 4 is an external perspective view seen from the direction of XX of FIG. This shows a state when the paper is discharged outside.

3 and 4, the locking portion 4 fixed to the operating member 3 has a slope 4a facing obliquely downward to the right so as to face the discharge side wall 2c of the case body 2, and a bottom surface of the case body 2. A sliding portion 4b that slides with respect to 2d is formed as shown in the drawing, and is prepared as a resin or metal part different from the iron member as the operating member 3, and is fixed by caulking or the like. .

The operating member 3 has a slightly larger hole 3a to be inserted into the shaft 5 implanted in the base 1, and has a bamboo-shaped or coil-shaped shape after being inserted into the shaft 5. After the compression spring 7 is inserted from above and the flat washer 8 is inserted, the compression spring 7 is provided in a compressed state by setting the E-ring 9 in the groove portion of the shaft body 5, so that the operating member 3 is configured as shown in FIG. Is constantly urged to move to the position shown by the solid line. When the case body 2 is discharged from the biased state by the discharge mechanism 10 in the direction of the arrow, the discharge side wall 2
c rides on the inclined surface 4a of the locking portion 4 so that the locking portion 4
Is generated to move the operating member 3 to the position shown by the broken line. At this time, since the operating member 3 attempts to return to the position shown by the solid line, when the case body 2 is ejected, the sliding portion 4b of the locking portion 4 slides against the bottom surface 2d, so that the case body is not braked. Will be possible.

After the case body 2 is discharged in this way, the operating member 3 waits in the recess 1d of the base 1 as shown in FIG.

FIG. 5 is an external perspective view illustrating another embodiment of the operating member and the spring. In this drawing, the same reference numerals are given to the components already described, and the description is omitted. The locking portion 4 is formed integrally with the operating member 3 by bending. Further, the torsion spring 20 is configured such that the compression spring portion is integrally formed as shown in the drawing, so that the function of the above-described tension spring and the function of the compression spring are combined. With the configuration shown in FIG. 5, further cost reduction can be realized.

As described above, according to the present invention,
It is possible to provide a disk device capable of realizing cost reduction by a mechanism having both erroneous insertion prevention and braking upon ejection.
