[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION This invention relates to a thin file having a narrow back width.

[0002]

2. Description of the Related Art When a document is spelled into a file for each small target item, a very thin file may be required. With conventional files, binding and removal are inconvenient, and the binding holes are likely to be broken, and there is a problem that the spread is not good, especially when binding thick paper such as a chart.

[0003]

This invention has a back width of 10
It is a thin file within mm, has a good spread, is easy to spell and take out documents, does not cause holes, and is a thin file that can be used especially for thick paper such as medical records. On the back cover, attach a fastener that integrally molded the board and the binding cord, and on the front cover, attach a fixture that consists of a base plate with a slit through which the binding cord can pass. It has a pawl that engages the rim.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an opened file of the present invention. A file 10 comprises a spine cover 1, a back cover 2 and a front cover 3, and the spine width of the spine cover 1 is 10 mm or less. Is.

The back cover 2 has a substrate 21 and a binding cord 2
A fastener 20 formed by integrally molding 2, 22 is a substrate 21.
Are attached to the back cover 2 by fixing them.

On the front cover 3, a fixture made of a base plate 31 having a slit 32 through which the above-mentioned binding cord 22 can pass is fixed.

The material of the file, fastener, fixture, etc. may be a desired material such as synthetic resin.

2 is a view showing the fastener 20 taken out, FIG. 3 is a view showing the fixture 30, and FIG. 4 is an enlarged view of the claw 23 surrounded by a dotted line A in FIG. And the binding straps 22 and 22 are integrally formed, and the claw 23 is formed near the tip of the binding strap 22. In the example of FIG. 4, the cut and raised shape is provided.

As shown in FIG. 3, the fixture 30 has a base plate 31 fixed to the front cover 3 and slits 32, 32 through which the binding cord 22 can pass. The slit 32 has a front edge 33.

FIG. 5 shows a state in which a document is bound. The binding string 22 is passed through the binding hole 41 of the document 40, and the binding string 22 is passed through the slit 32 of the base plate 31.
Therefore, even if the front cover 2 is opened and closed, the spelling cord 22
Since the paper slides in the slit 32, no force is applied to the document 40 and the binding hole 41 is not damaged.
Further, even if the front cover 2 is opened, the fastener 20 does not come off from the slit 32, so that the document does not come off from the fastener and the spread is improved.

FIG. 6 shows a state in which the document 40 is to be reviewed, in which the claw 23 of the binding cord 22 is engaged with the front edge 33 of the slit 32 of the base plate 31. FIG. 7 is an enlarged view showing the engaged state. In this case, since the binding cord 22 has a chevron shape, even if the document 40 is thick paper such as a medical chart, the spread is improved.

FIG. 8 is a diagram when a file is bound, and FIG. 9 is an explanatory diagram of the relationship between each cover of the file, the document 40, the fastener 20, and the fixture 30, and the binding string 22 of the fastener 20 is Through the binding hole 41 of the document 40, the base plate 3
Since it has passed through the slit 32 of No. 1, when the front cover 3 is opened and closed, the states shown in FIGS. 5 and 9 are obtained. That is, when the front cover is opened, the binding cord 22 slides in the slit 32 to be in the state of FIG. 5, and when the front cover is closed,
The state in which the documents are bound is shown in FIG.

[0013]

[Effect] The thin file of the invention of this application has the above-mentioned structure, and even if it is thin, it is easy to stitch and take out documents, and the file does not damage the binding holes of documents and has a good spread. I was able to.
