JPH10338286A - Housing case for minidisk - Google Patents

Abstract

PROBLEM TO BE SOLVED: To use a housing case as an operation tool preventing piece of miselimination and improve the operability of the piece, by providing an operational projection enabling sliding operation of the preventive piece of miselimination for detection of recording possibility, in the case body of the housing case containing a minidisk so as to freely put the disk therein or take it out. SOLUTION: A small operational projection 13 is formed at the opening upper edge 11a of a case body 10 or at a position near one end of the right and left directions of the opening lower edge. The dimensions of the operational projection 13 are determined in the relation of the dimensional position of a cartridge case 2 and a preventive piece of miselimination. The protruded length of the operational projection 13 is larger than the level difference between the external face of one side face 5 of the cartridge case 2 and the detection face 6a of the preventive piece 6 of miselimination and the tip 13a thereof is made to have a wedge-shaped form. And hence, the opening of the case body 10 is arranged to face one side face 5 of the minidisk so as to cross with the right and left longitudinal direction thereof and the tip 13a of the operational projection 13 is inserted between the knob 6b of the preventive piece 6 of miselimination and the inside wall of the recess 7 adjacent to the knob and slid to one lateral direction.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage box for storing mini disks such as magneto-optical disks.

[0002]

2. Description of the Related Art In a mini-disc, similarly to a tape cassette such as an 8 mm cassette or a DAT cassette, an erroneous erasure prevention piece for detecting whether or not recording is possible can be slid on a part of an outer surface of a cartridge case by an external operation. It is provided in.

[0003]

However, the mini-disc has a built-in disc having a diameter of 64 mm, and the entire disc is reduced in size and thickness. Therefore, the size of the erroneous erasure prevention piece itself is limited. . For example, as shown in FIG.
A concave portion 7 is provided on one side surface 5, and an erroneous erasure preventing piece 6 is slidably provided in the concave portion 7. The size of the erroneous erasure prevention piece 6 is very small with a width w of about 3 mm, and the knob 6b provided on the erroneous erasure prevention piece 6 enters inside so as not to protrude from the outer surface of one side surface 5 of the cartridge case 2. It is very difficult to operate.

Normally, this erroneous erasure prevention piece 6 is operated with a fingertip. However, since the fingertip does not catch on the erroneous erasure prevention piece 6 poorly, the nail is inserted into a narrow gap between the knob 6b of the erroneous erasure prevention piece 6 and the inner wall of the concave portion 7 and slides. Problems such as cracking and turning over may occur.
In order to avoid such operational problems, a thin-pointed ball-point pen or a mechanical pen may be used as an auxiliary tool. However, this requires time and effort to search for such an auxiliary tool each time the erroneous erasure prevention piece 6 is operated. There is such a disadvantage.

An object of the present invention is to pay attention to the fact that a mini disk is stored in a storage box when not in use, so that the storage box can be used as a jig for operating an erasure preventing piece,
This is to improve the operability of the erroneous erasure prevention piece.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS (First Embodiment) A first embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a mini-disc incorporating a magneto-optical disc having a diameter of 64 mm as described above. The mini-disc 1 has a shutter 4 on one of the left and right sides 3 of a cartridge case 2 and a left and right of one side 5 on the rear side. Near the one end in the direction, there is provided a concave portion 7 provided with an erroneous erasure preventing piece 6 for detecting whether or not recording is possible, slidably in the left-right direction. As shown in FIG. 2, the erroneous erasure preventing piece 6 provided in the concave portion 7 of the cartridge case 2 is provided so as to protrude vertically on a detection surface wall 6a having a width size w of about 3 mm and an outer surface of one end of the detection surface wall 6a. And a knob 6b having a semicircular cross section. The knob 6b is housed inside the cartridge case 2 so as not to protrude from the outer surface of the one side surface 5 of the cartridge case 2. Incidentally, the protrusion height of the knob 6b from the outer surface of the detection surface wall 6a is about 0.9 mm.

As shown in FIG. 3, the storage box for storing the mini-disc 1 in a removable manner is formed by plastically molding a box body 10 into a book case shape having a slot 11 on one side. Opening upper and lower edges 11a
At the center in the left-right direction of 11b, notches 12 are formed for picking out the mini-disc 1 so that a part of the mini-disc 1 is exposed when the mini-disc 1 is stored, so that the mini-disc 1 can be easily taken in and out. .

A small operation projection 13 for slidably operating the erroneous erasure prevention piece 6 is provided near one end in the left-right direction of the upper opening edge 11a or the lower opening edge 11b of the box body 10. The size of the operation protrusion 13 is set based on the dimensional positional relationship between the cartridge case 2 and the erroneous erasure prevention piece 6. For example, the width a of the operation protrusion 13 is 2.5 mm with respect to the width of the erroneous erasure prevention piece 6 of 3 mm.
Set to 2.8 mm. In this case, if the width a of the operation protrusion 13 is smaller than the above-mentioned dimension, the strength of the operation protrusion 13 itself is reduced, which is not desirable.

The amount of protrusion b of the operation projection 13 from the upper opening edge 11a or the lower opening edge 11b is determined by the outer surface of one side surface 5 of the cartridge case 2 and the detection surface wall 6 of the erroneous erasure prevention piece 6.
It is preferable that the step size d is set to be larger than the step size d (see FIG. 2) in order to slide the erroneous erasure preventing piece 6 stably and surely. For example, when the step size d is 1.2 mm, the protrusion amount b of the operation projection 13 is set to about 1.5 mm. Further, from the viewpoint of safety, it is preferable that the corner of the tip 13a of the operation projection 13 has a small radius. Further, when the operation projection 13 is formed in a wedge shape that gradually becomes thinner toward the tip 13a, the tip 13a can be more easily inserted into the gap between the knob 6b of the erroneous erasure prevention piece 6 and the inner wall of the recess 7 adjacent thereto.

In order to slide the erroneous erasure prevention piece 6 of the mini disk 1 by using the operation projection 13 attached to the storage box, as shown in FIG. The inlet / outlet 11 is oriented to one side surface 5 of the mini-disc 1 so as to be perpendicular to the left-right longitudinal direction, and the tip 13a of the operation protrusion 13 is a gap between the knob 6b of the erroneous erasure prevention piece 6 and the inner wall of the concave portion 7 adjacent thereto. And slide in one direction. Thus, the small erroneous erasure prevention piece 6 can be easily and reliably slid.

In the above embodiment, it is advantageous to form the operation projection 13 integrally with the box body 10 to facilitate processing, but the operation projection 13 is formed separately from the box body 10. Can be attached to a desired portion of the box body 10. Further, the operation protrusion 13 is not limited to the upper edge 11a or the lower edge 11b of the opening of the box main body 10, but may be provided at other places.

(Second Embodiment) FIGS. 5 to 7 show a second embodiment of the present invention. In this embodiment, the box body 1 of the storage box is used.
The upper and lower cutouts 14 and 15 are provided near one end in the left and right direction of the upper and lower edges 11a and 11b of the opening 11 of the opening 11 so that the operation protrusion 13 is formed on the inner inner wall 14a of the upper cutout 14. They are integrally formed so as not to protrude outward from the cutouts 14. The notch width e of each of the upper and lower cutouts 14 and 15 is set to a size slightly larger than the thickness of the mini disc 1. For example, when the thickness of the mini disc 1 is 5 mm, the notch width e is set to about 5.5 mm. The width a of the operation projection 13 and the projection amount b from the inner rear wall 14a,
The shape and the like of the tip 13a of the operation projection 13 are the same as in the first embodiment. Notch width e of upper notch 14
By making the width a of the operation projection 13 smaller than that, the gaps slightly larger than the wall thicknesses of the upper and lower walls of the opening 7 of the concave portion 7 of the mini-disc 1 are provided on both sides in the width a direction of the operation projection 13 in the cutout portion 14. 141 and 141 are formed. Of course, the operation protrusion 13 can be provided on the inner back wall 15a of the lower cutout 15 instead of the upper cutout 14.

The operation projection 13 of the storage box configured as described above.
In order to slide the erroneous erasure prevention piece 6 of the mini-disc 1 by using the box body 10, as shown in FIGS. To the right and left longitudinal directions. Thus, the gaps 141 and 141 formed on both sides of the operation protrusion 13 in the cutout portion 14 are inserted into the upper and lower walls of the opening of the concave portion 7, and the front end 13 a of the operation protrusion 13 is adjacent to the knob 6 b of the erroneous erasure prevention piece 6. The upper and lower cutouts 14 and 15 are slid in the left and right directions along the one side surface 5 of the cartridge case 2 and the upper and lower surfaces, while being inserted into the gap with the inner wall of the concave portion 7. Then, the box body 10 is divided into upper and lower cutouts 14.
15 can be slid straight and stably in the left-right direction along one side surface 5 of the cartridge case 2, so that the erroneous erasure prevention piece 6 can be operated more reliably.

If the operation projection 13 is stored in the cutout portion 14 or 15, the resin film may be broken when the mini disk 1 is inserted into the box body 10 of the storage box and shrink-wrapped with the resin film when packing the product. There is no danger of damaging the projections 13 and the like, and the packaging property is excellent. In addition, the operation projection 13 is safe because the hand is not injured when the mini-disc 1 is taken in and out of the box body 10, and the operation projection 13 can be prevented from touching other objects when not in use. Thus, it is possible to prevent the operation protrusion 13 from being damaged or being damaged by other objects.
