Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a storage box for storing and storing minidisks such as magneto-optical disks.
[0002]
[Prior art]
Also in the 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 recording is possible is provided on a part of the outer surface of the cartridge case so as to be slidable by an external operation. .
[0003]
[Problems to be solved by the invention]
However, since the mini-disc contains a disc having a diameter of 64 mm, and the entire disc is reduced in size and thickness, the erroneous erasure prevention piece itself has a size restriction. For example, as shown in FIG. 1, a miniature magneto-optical disk is provided with a recess 7 on one side surface 5 of the cartridge case 2, and an erroneous erasure preventing piece 6 is slidably provided in the recess 7. The size of the erroneous erasure prevention piece 6 is very small with a width size 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. Therefore, it is very difficult to operate.
[0004]
Normally, the erroneous erasure prevention piece 6 is operated with a fingertip. However, since the fingertips on the erroneous erasure prevention piece 6 are poorly hooked, the nail is inserted into the narrow gap between the knob 6b of the erroneous erasure prevention piece 6 and the inner wall of the recess 7 and is slid. There is a risk of problems such as cracking and turning.
In order to avoid such operational problems, a thin-pointed ballpoint pen or a mechanical pencil may be used as an auxiliary tool, but this requires time and effort to search for such an auxiliary tool each time the erroneous erasure prevention piece 6 is operated. There is a disadvantage of this.
[0005]
An object of the present invention is to make it possible to use the storage box as a jig for operation of an erroneous erasure prevention piece by paying attention to the fact that the mini disk is stored and stored in the storage box when not in use. The point is to improve the operability.
[0006]
[Means for Solving the Problems]
The invention according to claim 1 of the present invention is a storage box in which a mini-disc 1 provided with an erasure prevention piece 6 for detecting whether recording is possible or not is slidable by an external operation. An operation projection 13 is provided to enable the erroneous erasure prevention piece 6 to be slid.
[0007]
In the invention according to claim 2 of the present invention, the mini-disc 1 provided with a mis-erase prevention piece 6 for detecting whether recording is possible or not is slidable by an external operation on a part of one side surface 5 of the cartridge case 2 can be taken in and out. In the storage box to be stored, the box body 10 is formed in a bookcase shape having a slot 11 for the mini-disc 1. Then, upper and lower notches 14 and 15 having notch widths e slightly larger than the thickness of the mini-disc 1 are provided on the upper and lower edges 11a and 11b of the opening / closing port 11 of the box body 10 so as to face each other. An operation protrusion 13 that allows the erroneous erasure prevention piece 6 to be slidable protrudes outwardly from the notch 14 (or 15) on the inner back wall 14a (or 15a) of one notch 14 (or 15). It is provided so that it may not occur.
[0008]
[Action]
According to the first aspect of the present invention, the small erroneous erasure preventing piece 6 of the mini disk 1 can be easily and reliably slid by the tip of the operation projection 13 while holding the box body 10 in the hand.
[0009]
When the operation protrusion 13 is stored so as not to protrude outward from the notch portion 14 as in the invention described in claim 2, the operation protrusion 13 is used when the mini-disc 1 is taken in and out of the box body 10. It is safe without injuring your hands. Further, it is possible to prevent the operation protrusion 13 from touching other objects when not in use, and to prevent the operation protrusion 13 from being damaged. Further, when the mini-disc 1 is housed in the box body 10 as in the prior art and is packed by shrink wrapping using a resin film, the packing can be easily performed and the operation projections 13 are not damaged.
[0010]
When the erroneous erasure preventing piece 6 is operated by the operation projection 13, the upper and lower cutout portions 14 and 15 having the notch width e slightly larger than the thickness of the mini-disc 1 are arranged on the upper and lower sides around the erroneous erasure preventing piece 6 of the cartridge case 2. Since it can be slid straight along the wall surface, it becomes easier to operate the erroneous erasure prevention piece 6.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
(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 is provided with a shutter 4 on one side surface 3 of the left and right sides of the cartridge case 2 and left and right sides of the rear side surface 5. Near one end of the direction, there is provided a concave portion 7 provided with a erasure preventing piece 6 for detecting whether recording is possible or not so as to be slidable 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 in the vertical direction on the detection surface wall 6a having a width size w of about 3 mm and the outer surface side of one end of the detection surface wall 6a. The knob 6b has a semicircular cross section, and the knob 6b is housed in a state where the knob 6b enters inside so as not to protrude from the outer surface of the one side surface 5 of the cartridge case 2. Incidentally, the protruding height of the knob 6b from the outer surface of the detection surface wall 6a is about 0.9 mm.
[0012]
As shown in FIG. 3, the storage box for storing the mini-disc 1 in a removable manner is formed by plastic molding a box body 10 into a bookcase shape having a loading / unloading port 11 on one side. In the left and right central portions of 11a and 11b, notch portions 12 and 12 for picking out the knob are formed so that a part of the mini disc 1 is exposed when the mini disc 1 is accommodated so that the mini disc 1 can be easily inserted and removed. Yes.
[0013]
A small operating projection 13 that allows the erroneous erasure preventing piece 6 to be slidable is provided near one end in the left-right direction of the upper edge 11a or the lower edge 11b of the box body 10. The size of the operation protrusion 13 is set based on the dimensional position relationship between the cartridge case 2 and the erroneous erasure prevention piece 6. For example, the width a of the operation protrusion 13 is set to 2.5 mm to 2 mm with respect to the width 3 mm of the erroneous erasure prevention piece 6. Set to .8mm. In this case, if the width a of the operation protrusion 13 is narrower than the above dimension, the strength of the operation protrusion 13 itself is lowered, which is not desirable.
[0014]
Further, the protrusion amount b of the operation protrusion 13 from the upper edge 11a or the lower edge 11b of the opening is a step dimension d between the outer surface of one side surface 5 of the cartridge case 2 and the detection surface wall 6a of the erroneous erasure prevention piece 6 (FIG. 2). It is preferable to set a larger value in order to slide the erroneous erasure preventing piece 6 stably and reliably. For example, when the step size d is 1.2 mm, the protrusion amount b of the operation protrusion 13 is about 1.5 mm. Furthermore, it is preferable that the corner | angular part of the front-end | tip 13a of the operation protrusion 13 is made into a small round shape from a safety consideration. Further, when the operation protrusion 13 is formed in a wedge shape that gradually becomes thinner as it reaches the tip 13a, the tip 13a is 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.
[0015]
In order to perform the sliding operation of the erroneous erasure preventing piece 6 of the mini disk 1 using the operation projection 13 attached to the storage box in this manner, as shown in FIG. And the tip 13a of the operation projection 13 is 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. Slide in one direction. Thereby, the small erroneous erasure preventing piece 6 can be easily and reliably slid.
[0017]
(Second embodiment)

In this embodiment, upper and lower cutout portions 14 and 15 are provided in a vertically opposed manner near one end in the left-right direction of the opening upper and lower edges 11a and 11b of the loading / unloading port 11 of the box body 10 of the storage box. The operation projection 13 is integrally projected on the inner back wall 14a so as not to protrude outward from the cutout portion 14. The notch width e of each of the upper and lower notches 14 and 15 is set to a dimension slightly larger than the thickness of the mini disk 1. For example, when the thickness of the mini disk 1 is 5 mm, the notch width e is set to about 5.5 mm. The width a of the operation protrusion 13, the protrusion amount b from the inner back wall 14 a, the shape of the tip 13 a of the operation protrusion 13, etc. are the same as in the first embodiment. By making the width a of the operation projection 13 smaller than the notch width e of the upper cutout portion 14, the opening upper and lower wall portions of the recess 7 of the minidisk 1 are formed on both sides in the width a direction of the operation projection 13 within the cutout portion 14. Clearances 141 and 141 slightly larger than the wall thicknesses are formed. Of course, the operation protrusion 13 can be provided on the inner back wall 15 a of the lower notch 15 instead of the upper notch 14.
[0018]
In order to slide the erroneous erasure preventing piece 6 of the mini disk 1 using the operation projection 13 of the storage box configured as described above, the box body 10 is held in the hand as shown in FIGS. The loading / unloading port 11 faces the one side surface 5 of the mini disk 1 so as to be orthogonal to the left and right longitudinal direction. Thus, the gaps 141 and 141 formed on both sides of the operation projection 13 in the notch 14 are inserted into the upper and lower walls of the opening of the recess 7, and the tip 13 a of the operation projection 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 one direction along the side surface 5 and the upper and lower surfaces of the cartridge case 2 while being inserted into the gap between the inner wall of the recess 7. Then, the box body 10 can slide the upper and lower cutouts 14 and 15 along the one side surface 5 of the cartridge case 2 straight and stably in the left-right direction, so that the erroneous erasure preventing piece 6 can be operated more reliably. be able to.
[0019]
