Claims

[Scope of utility model registration request]

A light pen having a point light source, a liquid crystal display having dot-like display images arranged vertically and horizontally, and a plurality of optical sensors held integrally with the liquid crystal display and corresponding to the dot-like display pixels, respectively. scanning the outputs of the plurality of optical sensors; scanning the outputs of the plurality of optical sensors;
A single mark position detection circuit that detects the coordinate position of the light pen applied to either the display surface of the liquid crystal display or the light receiving surface of the photodetector, and the light pen coordinates detected by the coordinate position detection circuit. Logic " to the address corresponding to the position
1, and a display control circuit that sequentially reads out the stored information in the memory and displays it on each display pixel of the liquid crystal display, the display surface of the liquid crystal display and the photodetector. An information input/output device configured to mainly input desired information into the trajectory of a light pen applied to any of the light receiving surfaces of the device, and to display the input information on the display surface of a liquid crystal display.
