PURPOSE:To simplify the software and to improve the operability, by providing an operation section selectively setting color information for a light pen main body, setting the color information at the light pen side, and simultaneously inputting position and color information with one operation. CONSTITUTION:A conical section 12 of a light pen main body 1 is formed with a transparent member and three kinds of light sources are incorporated. The shaft is provided with a color information set operation section 14 and an electrical constitution as shown in Figure. Rings 14a-14e are connected to a changeover switch 15a, and resistors 15b-15e. The switch 15a designates the standard color. The resistors 15b, c, d are provided corresponding to the three primary colors and the density of the colors is varied and outputted to a CRT2. The three primary colors are given in a specified ratio through the operation of the rings 14b, c, d, and the desired color information is provided through the mixing of colors. The light sources 16a, b, c are illuminated in response to the said ratio corresponding to the color components. The light is monitored at the circumference of the conical section 12. |
