BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plastic file sheet for storing a mounted film slide in a see-through manner.

[0002]

2. Description of the Related Art A mounted film slide storage file sheet in which a plurality of slide storage recesses defined by bars extending in the vertical and horizontal directions is formed in a relatively rigid plastic sheet is disclosed in, for example, Japanese Utility Model Publication No. 48-36836. It is publicly known as described in the gazette. In this file sheet, a mounted film slide storage concave section defined by a plurality of vertical rails and a plurality of horizontal rails is formed in the sheet body. Further, a pair of ear plates are formed so as to project into the recess so as to form a pair from the side walls of the crosspieces facing each other. The earplate engages a mounting edge of a film slide housed in the recess and acts to hold the film slide in the recess. As another type of file sheet for accommodating a mounted film slide, a structure described in JP-A-60-198296 is known. This file sheet has a structure in which a back plate and a front plate formed of a soft plastic sheet are overlapped and bonded. By appropriately determining the joining pattern between the back plate and the front plate, a plurality of mounted film slide storage pockets are formed between the two plates. Japanese Patent Application Laid-Open No. 60-198296 describes that the back plate is formed of a transparent or translucent sheet.

[0003] These conventionally known file sheets can be displayed on a screen of a large number of stored slides by placing the mounted film slides on a diffusion plate of a light box in a stored state. However, when trying to see the file sheet alone through the light without using the light box, it is not possible to observe the whole with uniform brightness due to the influence of the direction of the light. Also, in the case where a plurality of file sheets are bound in a book shape and viewed one by one, the light from behind is not sufficiently uniform, and it is difficult to observe the slide screen. Japanese Patent Application Laid-Open No. Sho 60-198296 describes that the back plate is made translucent. Thus, by making the back plate translucent, light can be diffused, and uniform illumination from the back surface may be achieved. However, this publication does not disclose how to obtain a translucent state. The most common way to achieve a translucent state in plastic materials is to incorporate pigments into the plastic material. However, when a translucent state is obtained by the incorporation of pigments, the effect of light diffusion may be achieved to some extent by the pigment, but the amount of transmitted light is reduced, the screen becomes darker as a whole, and the fluoroscopy is reduced. It becomes difficult.

[0004]

[Problem to be Solved by the Invention] The present invention solves the above-mentioned problem in the conventional file sheet for storing a film slide with a mount, and sufficiently diffuses light from the back surface to make the stored slide as a whole. It is an object of the present invention to provide a file sheet for mounting a film slide with a mount, which allows a fluoroscopic observation at various brightness.

[0005]

According to one aspect of the present invention, a file sheet includes a sheet body formed of a relatively rigid plastic in a rectangular shape. The sheet main body is formed with a mount-mounted film slide storage recess partitioned by a plurality of vertical rails and a plurality of horizontal rails. A pair of ear plates project from the side walls of the vertical bar or the horizontal bar facing each other into the recess so as to form a pair. The earplate engages a mounting edge of a film slide housed in the recess to hold the film slide in the recess. As a feature of the present invention, at least a region corresponding to the bottom of the concave portion of the sheet main body is formed as a diffusion surface by a double-sided mat finish. In another aspect of the present invention, the file sheet is formed by overlapping and bonding a back plate and a front plate formed of a soft plastic sheet. By appropriately determining the adhesive pattern between the back plate and the front plate, a plurality of mounted film slide storage pockets arranged in a row in one direction or in a matrix in a vertical and horizontal direction are formed. As a feature of the present invention, the front plate is made of transparent plastic, and the back plate is made of a transparent plastic sheet with a double-sided matte finish as a diffusion surface.

[0006]

[Function] In the present invention, when a film slide is stored in a file sheet and observed through light, the light is uniformly diffused by the diffusion surface of the matte finish, so that the entire film sheet has substantially uniform brightness. You can observe it. In addition, since the diffusion surface has a matte finish on both sides, the loss of light amount is relatively small, and the screen can be made brighter than the one made translucent by a pigment.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. Referring to FIG. 1, there is shown a rectangular mounted film slide storage file sheet 1 formed by molding a relatively rigid plastic sheet. The file sheet 1 has a plurality of horizontal rails formed in parallel between the edges 1a, 1b, 1c, 1d formed to protrude around the circumference and the vertical edges 1c, 1d. 2, and a seat body having a vertical bar 3 formed parallel between the lateral edges 1a and 1b. As is clear from the figure, each vertical bar 3 is formed intermittently. Each horizontal rail 2, vertical rail 3, and edges 1a, 1b, 1c, 1d form a plurality of mounted film slide storage recesses 4 arranged in rows and columns. A pair of ear plates 5 and 6 projecting toward the concave portion 4 are formed at the upper edge portion 1a and the horizontal rail 2 below the upper edge portion 1a. These ear plates 5, 6 are formed by punching from the sheet body. A pair of ear plates 5, 6 protruding toward the recess 4 are similarly formed on the lower edge 1 b and the horizontal rail 2 above the same, at positions facing each other. Similarly, paired ear plates 6 are formed on two opposing horizontal rails 2. On one vertical edge 1c, a binding hole 7 for binding the file sheet 1 to a binder or the like is formed.

The mount film slide 8 is inserted into the recess by sliding the mount film slide 8 into the recess 4 from the edge thereof. In this state, the ear plates 5 and 6 hold the slide 8 in the recess 4 while holding down the edge of the mount. As a feature of the present invention, the file sheet 1 has a diffusion surface by a double-sided mat finish in a region corresponding to the bottom of the concave portion 4. FIG. 2 shows a state in which the film slide 8 is stored in the file sheet 1 shown in FIG. Since the bottom area of the storage recess 4 of the file sheet 1 is a diffusion surface formed by a double-sided mat finish, the light from the fluorescent lamp 9 is diffused, and the slide stored in the file sheet 1 is substantially uniform as a whole. You can see through with brightness. FIG. 3 shows a state in which a plurality of file sheets 1 are bound to a binder 10 in a book shape, and the film slide 8 is seen through while being turned one by one. Also in this case, the entire film slide can be seen through the interior illumination lamp 11 with uniform brightness. FIG. 4 shows another embodiment of the present invention. The file sheet 20 shown in FIG. 4 includes a back plate 21 and a front plate 22. As shown in FIG. 4B, the back plate 21 has a flat shape, and a diffusion surface is formed by a double-sided mat finish. The front plate 22 is formed of a transparent plastic, and is joined to the back plate 21 in a pattern shown by a shaded line in FIG. Further, the surface plate 22 is cut by a plurality of horizontal cut lines 23 spaced apart in the vertical direction, and a plurality of pockets 24 having insertion openings 22a are formed at the positions of the cut lines 23. The film slide 8 is inserted into the pocket 24 from an insertion opening formed by the cut line 23. Also in this file sheet 20, a hole 25 for binding the file sheet 20 to a binder or the like is formed along one of the vertical edges.

Also in this embodiment, since the back surface plate 21 is formed as a diffusion surface by a double-sided mat finish, light from the back side is diffused and transmitted through the file sheet 20. Therefore, it is possible to see through the film slide 8 stored in the file sheet 20 with uniform brightness.

[0010]

According to the present invention, since the double-sided mat finish is applied to the bottom area of the file slide storage portion of the file sheet or the back surface plate to form a diffusion surface, the film slide 8 stored in the file sheet can be evenly distributed. It is possible to see through with great brightness.
