This invention relates to nanolithic optical/optical switches and thousand-board devices.

2, 3" Yu Liri] Mouth L Fiber optic keyboards and switches are a one-to-one replacement for early light-to-optical keyboards. Reduces the number of light emitting diodes (LEDs) and detectors required It is interesting because it

One LED can illuminate a bundle of fibers, each fiber can be placed on the keyboard. Continue to separate keys. At each key, yet another fiber receives the transmitted light. and transmits it to a photodetector. If the key is pressed down, the light will illuminate the key the detector detects the absence of light as an operating signal. By multiplexing LEDs and detectors, keyboard matrices can be Only one LED is required for each row in the box, and only one LED is required for each column. Only one detector is required.

The problem with fiber optic keyboards is that all the fibers are connected to the keyboard matrix. However, it is difficult to mold and/or assemble it into a box. Automation It would be difficult to convert into a The cost of reducing the number of output devices would be overwhelming.

The main purpose of this invention is to create a new, novel and heretofore cheerful If you haven't, the best thing to do is to solve these and pond problems.

The purpose of this park is to meet the needs and demands of fiber elements or elements. The goal is to overcome assembly problems by avoiding

Another object of the invention is to provide a motor within the body in the form of a child board matrix. The first step is to create an integrated optical assembly.

comparison of inventions An integrated and molded batch of optical assemblies are arranged in columns and columns. lol! A low refractive index carousel flat planar plastic with a matrix of PJ grooves. a base member, and the groove is molded into one surface of the large play member. forming said rows, and said grooves having molded grooves 4t in opposite parallel planes of the member; forming the rows. The grooves in this row and column are made of plastic material Filled with fiber (later circular type resulting from using fiber bundles) Rather, it effectively creates a flat square 12 signs. The horizontal item is the top of the 4-crow member. and the vertical row is formed at the bottom of the base member.・Cross-illuminated dimensions of 6 rows and columns A curved tap is placed nearby, and each person has a curved tap (12 parts 1 and 1) has a through opening. The row tap is in the column tap direction [the middle direction of the intersection ), whereby the light from the horizontal parallel waveguide is directed into the vertical column waveguide (i.e. from the top of the trix to the bottom). Speed of light like opaque 211 material': f! The elements or key blades are mutually movable in the aperture row and have a 1'-2 optical Alternately block the light and keep it out of place.

To increase the optical coupling between the upper and lower waveguides, the keyblade is It may be formed from two plastic materials, one black and one transparent. Tooru The bright part transmits light when it enters the intersection area. The transparent part has two leads. 'a Reduce the effective optical float of the gap at the portal of the tube.

This has the effect of making the proboscis below the surface appear closer to the surface than it actually is. is similar to

In addition, yet another increase in optical coupling between the upper and lower waveguides can be created by molding lenses into a keyblade.

Preferred fruit 91 Another current use The features of this invention provide a single integrated molded optical assembly; The assembly is shown as a soil-board matritus in the preferred embodiment.

As shown in FIG. 1, the top and bottom surfaces 12 and 1A each have , a single hard piece of transparent plastic, generally rectangular or square in circumference, 1G It is molded to give a plurality of horizontal rows 16 with slight undercuts; These rows 16 extend from one outer circumferential end of the hole 1G to the opposite circumferential edge of the member 10. forming a recess or ridge in the top surface 18 of surface 12 extending a short distance; . A plurality of rows 20 having similarly undercut recesses or indentations 22 are It is molded on the opposite surface 14vj.

In the intersection area between groove 1B and groove 22 (work section and bottom), the upper and lower curves are taps 2A and 26 are respectively installed on the first blade as shown in FIG. 1A. and is shown more clearly in Section 2. Understand in the enlarged view of Figure 3 As shown, the preliminary tap 24 can be moved in two directions, namely from its origin and back. , and an opposed upper M-bent tap 26 direction extending from the facing surface 14 to the upper blade. down and bent.

At approximately the exact midpoint where the two cods 724 and 26 intersect, the window or 1028 is formed within member 10 and extends around the member 10, as shown clearly in FIG. ・＼ and this extend by j.

Low refractive index Dv! 1. Form the base plate member 10 of N2 and insert it into the grooves 18 and 20. By molding '4J*N+ with a high refractive index, the light from the light generator 32 is Light 30 is transmitted into and through the row grooves 18, via taps 24, and through the apertures. 2B, enter into the groove 22 of the row through the tap 26 on the lower side, and connect the light receiver 3 of the row. Received by 4. , the sharply curved taps 24 and 26 are substantially Note that we direct the light 30 across the gap without attenuation.

1st. Keyway Road 36 (located in a light passage position) shown circularly in Hess and Man 3 figures. is a transparent light passing portion 40 (or an aperture 41 as seen in FIG. 1A) and a light velocity It includes a blade 38 having one section 42. The key 36 is shown in the depressed position. The light passing portion 40 is the upper blade and lower guide. The two facing sides of tubes 18 and 22 adjacent the ends 44 and 46, respectively, so that the light 3○2 and 1026 The signal is passed through the negative 5 to form a signal at the optical receiver 34.

When the key 36 is released by a Jl spring (not shown), the light blocking portion 42 is opened. The light 307 . 1 light receiver 34 to 1 be placed. The keyblade includes an open portion 40 and an opaque or dotted portion 42 .

By combining the parameters and materials of 1026 and group v1138 twice, Therefore, the lens 48 in Fig. 1A has one wing on the key 1 and 36, and it By connecting the light between the upper blade and the lower blade) and the anel Togataki desk E”IG, l.
