点を有し、両者は相反する性質を有していた。<Problems to be solved by the invention> Conventional optical fiber sheets use circular monofibers as original fibers, so there is a limit to their information transmission ability.For example, when transmitting images or signals, optical information transmission is difficult. The smaller the diameter of the original fiber, the higher the resolution and the better the accuracy of image and signal transmission.On the other hand, the smaller the diameter of the fiber used, the easier it is to handle and assemble. On the other hand, if handling and processability are important, it is better to increase the diameter of the fiber. , the two had contradictory properties.

にある。<Means for Solving the Problems> In view of these points, the present inventors conducted studies with the aim of obtaining a high-quality optical fiber sheet that satisfies both ease of handling, ease of assembly, and information transmission performance. As a result, the present invention was completed, and its gist is that a multi-optical fiber with a substantially rectangular cross-section consisting of a large number of islands with optical transmission properties and a sea area surrounding the islands is connected to a plurality of multi-optical fibers. A source fiber sheet characterized in that the fibers are arranged in a planar manner so that adjacent fibers at at least one end of the arrangement are in contact with or in close proximity to each other and are bonded to each other;
It is in.

。Is Figure 1 an example of the original fiber sheet according to the present invention? The causes of strabismus shown in the appearance are as follows: (a) is a single-sided adhesive type that uses adhesive on one side, and (b) is a nine-sided adhesive type that uses adhesive on both sides. This is a fused type that is made by fusing together multi-fibers to form a sheet. In the figure, (1) is a multi-optical fiber, (2) is an adhesive, and (3) is an original fiber sheet. FIG. 2 is a cross-sectional view of an example of a multi-optical fiber used in the present invention. In FIG. 2, (1) is a multi-optical fiber, which is preferably made of glass for ease of handling. (21) is an island that becomes a pixel responsible for optical transmission;
(22) is Kaifu. As shown in the figure, it is preferable for the cross-sectional shape of the island portion (21) of the multi-optical fiber (1) to be circular in shape from the viewpoint of transmission. Also, in Figure 2, the island (
21) are arranged in a stacked bale structure in the sea part (22), and in order to improve transmission accuracy, this arrangement is preferred because it allows for the highest density arrangement. However, depending on the application, there may be some difference in performance, but a different arrangement may be used, for example, a square stacked arrangement in which the island portions (21) are arranged squarely on the left and right, and on the top and bottom.

その効力が大きい。The island part (21) forms a core-sheath structure consisting of a core that performs optical transmission and a sheath to improve it, and the size of the island part (21) and one multi-optical fiber (1 )
As for the number present in the diameter, it is suitable that the diameter is 5 to 200μ and the number is about 100 to 10,000. Such glass-based multi-optical fibers are disclosed in, for example, Japanese Patent Application No. 60-1.
It can be made by a composite spinning method as shown in No. 42985. The characteristic of the plastic multi-optical fiber (1) used in the present invention is that the 11c(-(7)) cross-sectional shape is approximately rectangular.Since the cross-sectional shape is approximately rectangular, the original When forming the fiber sheet (3), since the adjacent multi-optical fibers (1) are lined up without any gaps, the drop in the amount of light emitted from the fibers at the adjacent part of the fibers, etc., which tends to occur when circular fibers are used, and the double white Does not happen. Therefore, the original fiber sheet (3)
The effect is that uniform transmission performance can be obtained over the entire width of the image, and this effect is particularly great when surface transmission is required, such as image transmission.

る。The second feature is that the island portion (21), which is the minimum transmission unit, is small, which is extremely small compared to ordinary monofibers. Therefore, it is possible to completely solve the problem of the conventional method, which is the relationship between transmission characteristics, accuracy, and ease of handling.

影響などを考慮して選定すれば良い。@ In Figure 1, the multi-optical fiber sheet (3) shown in (a) and (b) is made by aligning the required number of multi-optical fibers (1) in Figure 2 so that adjacent fibers are in contact or close to each other. The adhesive is applied to one or both sides while maintaining that condition, and then dried or cured. Here, the adhesive (2) may be water-soluble, solvent-based, ultraviolet curing type, electron beam curing type, etc. These adhesives may be selected in consideration of various conditions such as productivity, adhesive strength, and the influence of curing conditions on the fibers.
接着剤(2)の塗布厚さは片面・両面の違い、用途、接
着剤の性状などにより選定決定すればよい。The coating thickness of the adhesive (2) may be selected and determined depending on whether the adhesive is on one side or both sides, the application, the properties of the adhesive, etc.

きくクローズアップされることになる。The fusion type shown in Figure 1 (01) does not use any adhesive at all, and the predetermined number of multi-optical fibers (+) are aligned and heated with an appropriate means such as hot air, far infrared rays, near infrared rays, etc. When the fibers (1) are brought together and brought into contact with each other, the adjacent portions of the fibers (1) are fused together, and the original fiber sheet (3) can be made without using an adhesive.In this case, (a) Although the adhesive strength between the multi-optical fibers (1) is slightly lower than that of the adhesive type lb), the advantages are that no extra component called adhesive is required and that the adhesive thickness can be reduced to zero. In particular, when the original fiber sheets (3) are laminated and used for image transmission, the adhesive (2) part does not contribute to optical transmission, so the effect of being 100% fiber will be greatly highlighted. .

It is also extremely useful industrially.
