った。(B) Prior Art In the prior art, as shown in FIG. 1, a lens 10. It is roughly composed of a light receiving element 12, a switch mechanism 14, and a lens l.
The light is focused by O and received by the light receiving element 12. At this time, when the pen is pressed against the CRT tube surface, it slides and the switch mechanism 14 is turned on. The contact method is often used. Such a switch mechanism requires precision and has to be designed compactly, so it is not easy to manufacture, and it is also fragile, has chattering problems, and has low reliability.
才だ、スイッチ機構をとくに設けず、受光時の動作確認
は、人間の指で軽く触れるだけで行なわれるものが存在
するが、ソフトウェア上及びインタフェースとしての論
理回路にも相当の負荷かかかつている。There are some devices that do not have a special switch mechanism and check the operation when light is received by simply touching it with a human finger, but this places a considerable load on the software and the logic circuit as an interface. .

回路か付加されていた。In any case, in the conventional example, the light receiving system is inserted at the tip of the light pen, so the light contains information other than the desired information as well as ambient light (for example, when the light is directed towards the lighting equipment). The output was unreliable. In fact, a complicated circuit was added to detect disturbance light.

It is preferably a photoconductive vinyl with a high optical refractive index and molded from transparent acrylic resin. The light-conducting bottle 26Lri is fitted into the stopper 27, or is wound around the spring 28. This is a 30Iri bottle bearing. In this way, the photoconducting pin 26 has a voltage of V! ! +i2
6a protrudes from the cylinder tip portion 24 by a certain distance so as to be retractable; however, the other end portion 26b,
It is beveled at 45 degrees. This is a support part in which the stopper 27 moves vertically according to the slide of the screw 3LH1 photoconductive pin 26. Further, a 32-pin photodetector, 34

However, when the CRT tube surface is on the dashed line shown in the drawing, that is, when the tube tip 24 is pressed against the tube surface 44, the light-conducting bottle 26 is moved by the spring 28 to its one end 2.
6 a is retracted, the other end 26 b is displaced to the dotted line region shown in the figure and reaches above the light receiving element 32 . Therefore, the transmitted light travels inside the photoconductive bottle 26 while being refracted and reaches the other end, and is also refracted at the oblique end to reach the light receiving element 3.
2. When the refractive index is high, light is not scattered to the outside and is transmitted in the axial direction.
