DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a film sheet storage board according to the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a film sheet storage board, and FIGS. 2 to 4 are enlarged sectional views of respective parts in FIG. In these figures, a film sheet storage board 10 includes a base sheet 11 having a square planar shape, and a transparent cover film 12 superposed on both sides of the base sheet 11.

The base sheet 11 is made of paper or a resin sheet. In this embodiment, an opaque white sheet is used. FIG. 1 of this base sheet 11
A binding hole 13 is formed at a plurality of upper and lower locations on the middle left side, and can be bound to a binder or the like (not shown) through the binding hole 13. Two arc-shaped cuts 14, 14 are formed in the upper part of the binding hole 13 at a position slightly to the right, and the inner area of the cut 14 is formed as a tongue piece 15 cut and raised in the opposite direction. (FIG. 3
reference). Notches 17 and 18 are formed in the upper right edge and the right edge portion of the base sheet 11, respectively, and punched portions 19 are formed in three upper and lower portions inside the notch 18.

The cover film 12 is provided in such a size that it covers an area extending from the middle portion in the left-right direction to the right end of the base sheet 11 in FIG. This cover film 1
Reference numeral 2 is configured by bending one sheet piece into two sheets, and the lower edge of the base sheet 11 is positioned inside the bent portion. Then, welding portions 21 are provided at the positions of the cutout portions 17 and 18 and the punching portion 19 formed in the base sheet 11, respectively.
A pocket 23 is formed with the left end edge of the cover film 12 as the entrance 22, and a film sheet 25 can be stored in the pocket 23. Here, the access opening 22 of the pocket 23 extends in the inclined direction in which the lower end in FIG. 1 is located on the left side of the upper end, and is set such that the storage depth on the lower side is relatively deep.

In the cover film 12, two drop-prevention portions 26 are formed at three locations on the bottom side of the pocket 23 opposite to the access port 22, ie, on the right side in FIG. As shown in FIG. 2 in an enlarged manner, the falling-off preventing portion 26 is formed by pressing or the like on the base sheet 11.
, The gap C between the base sheet 11 and the cover film 12 is reduced, and a holding pressure is applied to the film sheet 25 stored in the pocket 23. It is supposed to.

The cover film 12 has two press lines 27 formed along the opening 22. The press wire 27 is formed at a depth that does not break the cover film 12, and is provided so as to widen the gap C on the side of the entrance 22 by utilizing plastic deformation at the time of pressing.

In the film sheet storage board 10 thus configured, the film sheets 25 are stored one by one in the pocket 23. When this storage is performed, the gap C between the access port 22 is slightly widened, so that the film sheet 25 can be inserted without difficulty.

When the film sheet 25 is stored,
Appropriate holding pressure is applied to the surface of the film sheet 25 by the drop prevention unit 26, and therefore, careless dropping of the film sheet 25 is prevented. In this state, as shown in FIG. 3, the upper left end of the film sheet 25 not covered with the cover film 12 is supported by the cut and raised tongue piece 15. The film sheet 25 can be partially levitated.

Therefore, according to such a configuration, a large number of the film sheet storage sheets 10 can be bound together and bound to a binder, and the film sheet storage sheet 10 has a film 23 in each of the front and back pockets 23. Sheet 25
Can be stored respectively. Therefore, when the present film sheet storage board 10 is used as a film sheet used for an overhead projector, it is extremely easy to arrange the film sheets 25 in order according to the presentation in a lecture or the like. In addition, when a specific film sheet is searched for from among various types, it can be performed simply by turning over the film sheet storage board 10, and there is no possibility that various types of film sheets will be separated at this search.

The cover film 12 is provided in the pocket 2
Since the inlet / outlet 22 of the third sheet 3 is located at substantially the middle of the base sheet 11, the film sheet 25 can be slid on the surface of the base sheet 11 not covered with the cover film 12. In other words, the base sheet 11 can be used as a guide surface for the film sheet 25, and combined with the configuration in which the gap C between the access ports 22 is slightly widened, simple and quick insertion can be performed. .

Further, since the falling-off preventing portion 26 gives an appropriate holding force to the stored film sheet 25, the possibility that the film sheet 25 is shifted in the reverse insertion direction can be effectively avoided, and the film sheet storing board 10 is attached to the binder. When the sheets are bound at the binding position, the risk of folding the film sheet 25 at the binding side position can also be prevented.

Since the tongue piece 15 is formed at two places,
By setting the cut-and-raised directions to be the relative directions, the front and back film sheets 25 in the single film storage board 10 can be respectively floated, and it is extremely easy to pick out this kind of thin film sheet 25. I do.

In the above embodiment, the case where the film sheet 25 used for the overhead projector is stored is described. However, the film storing board according to the present invention can be used for storing other general films including negative films. Can be used.

The size of the cover film 12 is such that an area which does not cover the binding side of the base film 11 within the size of the film sheet 25 can be ensured, and the depth of the pocket 23 suitable for storing the film sheet 25 can be ensured. Can be set arbitrarily as long as is obtained.

Further, since the base sheet 11 only needs to function as a base material that allows the contents of the film sheet 25 to be stored to be clearly seen, the color of the base sheet 11 itself may be other than white, and any color may be used. Having a sheet can be adopted.
