管１はビデオ・メモリ２０に従つた画１面を与える。According to the present invention, the light pen 10 is provided with a light receiving element 3 including a photo diode, etc., and a display content adjustment section IL display section 12. For example, the display content adjustment unit 11 adjusts the dot size and line thickness using a linear potentiometer installed inside the shaft of the light pen, and adjusts the hue using a linear potentiometer installed at the tip of the shaft so that drawing operations can be performed smoothly. and an annular potentiometer installed in the section. Display content adjustment section 11 is normally provided by keyboard 8 in the circuit of FIG. The signals from this are applied to the graphic display circuit 7 and also to the display section 12 in the light pen. This display 12 may be an LED array installed at the end of the shaft of the light pen. Alternatively, it may be a color liquid crystal, or furthermore, light synthesized outside the light pen may be received through an optical fiber and displayed. Third
The figure is a more detailed view of FIG. 2, and the light pen 10 includes a light receiving element 3 that detects the luminance information on the cathode ray tube 1, an amplifier 13 that amplifies this output, and a format of the output figure on the cathode ray tube. It includes a display content adjustment section and an LED matrix display device 12. The display device 12 receives the output from the display content adjustment section and displays the format of the output graphic either graphically or numerically. The display content adjustment section is CRT display content storage circuit 1 in the figure.
4. Potentiometer 15 for specifying CRT display point size.
It includes a CRT display point brightness designating potentiometer 16 and a memory content fixing switch 18. A storage device 14 stores data for an image to be displayed in relation to a reference point or point designated by the light pen, the output of which is provided to the display device 12 via a display drive circuit 19. The cathode ray tube 1 provides a screen according to the video memory 20.
