Abstract

PURPOSE:To improve the quality of a transmitting picture and shorten a transmission time, and to reduce the size, weight, and cost of an applied equipment by irradiating a planar picture almost uniformly by a light emitting body layer. CONSTITUTION:The filmy light emitting body layer 22 is adhered to an optical transmission plate 21 while covered with an adhesive 7 except at lenses 2a on a plate surface facing to screen 17 of lenses 3a. Further, a light shielding layer 22a of carbon black is vapor-deposited at the part of the lens 3a where the light emitting body layer 22 is adhered so that no light is projected from the light emitting body layer 22 to the side of a picture plane 18. This constitution irradiates the screen 17 almost uniformly by the light emitting body layer 22, so an image on the screen 17 is transmitted onto an image plane 18 at a time by the optical transmission plate 21 which has a two-dimensional spread as a light image 15, which is formed. Thus, the quality of the transmit picture is improved and the transmission time is shortened; and the size, weight, and cost of the applied equipment are reduced.

The refractive index of (2d) is highest at the center of the sphere and has a distribution L7 that gradually decreases in the radial direction.

In addition to the above-mentioned crow, the flat plate (4) may also be a bright plastic snack or the like.

Rubber-like silicone bait fat OJ containing a black pigment is arranged in large numbers in an R-dense state and is placed in the gaps between and around these lenses (12).
Fill with light and fix the lenses (12) to each other 7
It is something that

The RLI gradient index lens U is made of a transparent material such as glass or plastic, and its refractive index is maximum at the axial center position and is approximately proportional to the square of the distance in the radial direction.
Since the light emitting end face is flat, it has a negative effect, and the light travels in a meandering manner with the '111 no.1 noke' center.

In the optical transmission plate (1) aυ as described above, a pair of lens parts (2a) to (2d) or 1 The lens (+21) receives the light flux from the image of characters, figures, etc. located at the position opposite to the 10,000 plate surfaces (1a) (11a) of the optical transmission plate (1), and the other side An erect, equal-sized optical image (+, bl) is formed at a position opposite to the plate surface (1b) (11b). Since the parts (2a) to (2d) or the lenses (l'lJv) are two-dimensionally arranged, the light flux from the image located on the same plane L as the image f (I4) is all reflected in the optical image (inner The image is formed into the same 1,000-sided image J2.

Therefore, the optical transmission board (]) I0 is the optical transmission board (1)
It is possible to transmit images on the screen that are approximately on the same plane as α1) to the image plane all at once.

By the way, in copying machines, facsimiles, etc. (('C), the screen rarely emits light by itself, and is usually illuminated by a light source. As shown in Figure 7, these optical transmission plates (11011
Place it near the end face of irt.
There are 8 comparisons to be irradiated by screen 07) by 16). However, since the inner surface (171 upper e) image that should be transmitted at once by the optical transmission board +IHI+ has a one-two-dimensional spread eb, the light source (16 ) is difficult to uniformly illuminate this screen (I7), and it is impossible to obtain a high quality light image on the image plane (1 group).

What is the intensity of the light incident on the optical transmission plate (1) αI)? d1
6. In order to make it uniform, use the 11 optical transmission plate (11) as shown in Figure 8.

Alternatively, in order to completely move the screen Qη and the image plane 0 barrel, a mechanical device for that purpose is required, and the optical transmission plate (1) 0υ?
There are problems in that the equipment to which it is applied is large, heavy, and expensive. There is also a point where it takes a relatively long time to transmit the entire image on the screen (17).

In view of the above-mentioned problems, the present invention solves the problem of flat images. Emergency button can be transmitted in a short time, and the applicable equipment is small.
The object of the present invention is to provide an optical transmission board that is lightweight and inexpensive.
