Abstract
PURPOSE:To reduce not only the cost but the fault factor, by forming a light pen with the main body of the light pen, the main light guide part, the secondary light guide part, the optical shutter part, a spring and an optical fiber. CONSTITUTION:When the tip of the light pen 1 is pressed to the CRT screen, the window part 11 of the optical shutter part 12 is positioned between the main and secondary reflection surfaces 3 and 7. The light sent from a spot of an image on the screen enters the main light guide part 2 via the input light surface 2a, enters the secondary light guide part 6 via the window part 11 after a full reflection on the main reflection surface 3, travels within the part 6 after reflected on the secondary reflection surface 7 and enters the photoelectric transducer 18 through the inside the optical fiber 10 to be converted into the electric signal through the photoelectric transducdr 19. The light pen of such constitution contains no electric parts, and as a result both the fault factor and the cost can be reduced greatly.
