Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bookcase type protective case for storing a tape cartridge.

[0002]

2. Description of the Related Art In this type of protection case, the fairness is 3-394.
There is 33 publication. There, a protective case is formed from a transparent or translucent plastic sheet, and with the tape cartridge loaded in the protective case, a title label attached to the outer surface of the tape cartridge,
You can visually check the remaining tape amount. Protective cases made of paper or opaque plastic sheets, which require less sheet material costs than transparent plastic sheets, are often used.

[0003]

As described above, the protective case formed of the transparent plastic sheet is more difficult than the case of using an opaque plastic sheet or paper as the forming material.
High material cost. As a transparent plastic material,
Polypropylene, which is tougher than other materials, is often used, but polypropylene has low transparency, and it becomes difficult to confirm the remaining amount of tape in a tape cartridge, for example, in a dark place.

The present inventor has previously proposed a protective case improved in the above points (Japanese Patent Application No. 6-152817).
issue). There, a protective case is formed from an opaque polypropylene sheet, which reduces the material cost. Further, an opening is provided in the main wall of the protective case, and a window for checking the remaining amount of the tape in the tape cartridge and a content display label adjacent to the window can be directly viewed through the opening from the outer surface of the protective case. The remaining time of the tape is displayed by printing around the window opening. However, since polypropylene is a crystalline plastic material, it is difficult to print because it does not dissolve in a solvent. In order to perform printing with sufficient durability, surface treatment such as flame treatment must be performed, and such printing treatment requires cost, and it is difficult to reduce the manufacturing cost of the protective case as a whole.

If an opening having the same size as the content display label is provided on the main wall of the protective case, the recorded contents can be known without removing the tape cartridge from the protective case. However, in this case, the case strength of the protective case is reduced, and there is a room for dust to enter through the opening, so that the disadvantage that the protective function is impaired cannot be avoided. In the conventional tape cartridge, the details of the recorded content of the tape are written on the content display label attached adjacent to the window for confirming the remaining amount of the tape. When recording, for example, one type of video software on one tape cartridge, the content can be sufficiently displayed only by the label. However, when recording various types of TV programs and images taken by a camera in one tape cartridge, it is difficult to write and display all the recorded contents with only one content display label.
Particularly, in the VHS type tape cartridge, since the content display label is attached to the inner surface of the case between the left and right windows, the writable label area is small.

Therefore, the object of the present invention is to reduce the manufacturing cost, the remaining amount of the tape can be easily viewed from the outer surface of the case even when the tape cartridge is stored, and the contents recorded on the tape can be displayed in detail. To provide a protective case that can. Another object of the present invention is to provide a label sticking area on the main wall of the protective case,
The contents recorded in the tape cartridge can be displayed in relation to the remaining amount of the tape, and it is particularly suitable for use in a VHS type tape cartridge.

[0007]

According to the present invention, as shown in FIG. 1, a window 12 for confirming the remaining amount of tape is provided on the outer surface of a main body case 11.
The protective case for accommodating the tape cartridge 10 provided with is targeted. The protective case 1 is made of an opaque sheet material, and includes a main wall 2 facing each other, and an upper wall 3, a lower wall 4, and a back wall 5 that connect the three peripheral edges of both main walls 2 to each other. It is formed in a bookcase type having a doorway 6. When the tape cartridge 10 is loaded in the protective case 1, the opening 20 through which the remaining amount of the tape can be viewed through the window 12 is formed in the surface wall of the main wall 2 facing the window 12.
To form. On the surface wall of the main wall 2, a sticking area 22 for the label 21 is provided in a portion adjacent to the opening 20, and at least the peripheral portion of the sticking area 22 is recessed from the outer surface of the main wall 2.

Specifically, the outer surface of the sticking area 22 is roughened. In order to distinguish the pasting area 22 from other surfaces,
The peripheral line 23 is formed by denting the surface wall of the main wall 2 by hot engraving. Alternatively, the entire outer surface of the sticking area 22 is recessed from the outer surface of the main wall 2. The opening 20 is formed in a long groove shape, and the pasting area 22 is formed from the vicinity of one short side portion of the main wall 2 to the vicinity of the other short side portion.

[0009]

The function of forming the protective case from the opaque sheet material is to reduce the material cost. Since the opening 20 is formed in the main wall 2 of the protective case, the opening 20
The remaining amount of the tape in the tape cartridge 10 stored in the case can be surely checked via the. When the label 21 for content display is attached to the attachment area 22 adjacent to the opening 20, the content recorded on the tape can be known in detail without removing the tape cartridge 10 from the protective case. Since the tape remaining time display 25 is printed on the label 21, it is not necessary to provide a print display portion on the protective case. Forming the peripheral edge of the sticking area 22 so as to be recessed from the surface wall of the main wall 2 makes it easier to determine the sticking position of the label 21, and accurately displays the remaining time display 25 of the tape printed on the label surface with respect to the opening 20. This is for the purpose of enabling the positioning of the sticking area 22 and also for permanently exerting the positioning effect of the pasting area 22. For example, when the pasting area 22 is displayed by printing, the printed line is easily rubbed and worn away every time the protective case is taken in and out.

The reason why the outer surface of the sticking area 22 is roughened is to facilitate the replacement of the label 21. The peripheral line 23 of the pasting area 22 can be formed at the same time in the process of hot-engraving the polygonal line of the boundary between the surface walls 2 to 5. When the entire outer surface of the sticking area 22 is formed to be recessed, it is possible to prevent the label 21 from coming into contact with another object and fading the displayed content or peeling it off. When the opening 20 is formed in a long groove shape, the reduction in case strength of the protective case can be minimized, and dust can be prevented from entering through the opening 20 as much as possible.

[0011]

According to the protective case of the present invention, as compared with the conventional protective case formed of a transparent plastic sheet,
The material cost and the cost for printing the tape remaining time display 25 can be reduced respectively to reduce the manufacturing cost and protect the tape cartridge 10 from the protective case 1.
The remaining amount of the tape can be confirmed through the opening 20 even when the tape is stored in. Moreover, the tape cartridge 10
It is possible to know the recorded contents of the tape cartridge 10 in detail, and only by reading the contents described on the label 21, the tape cartridge 10
It is possible to accurately judge whether or not the remaining tape amount matches the purpose of use to be recorded, and whether or not to save the recorded content.
