The light source 2 and the visual light cut filter 3 constitute the light source section 4 transmitting only infrared rays, the infrared rays 4 from the light source section 4 is emitted at the the rear side of the input plate, but only the character figure on the front side can be observed to human eyes. When the character is selected and the light pen 5 approches the character, the infrared rays transmitted with the pattern turning over the pattern code is detected with the light pen. It is inputted to the character code generator 6 to output the character code.
