Abstract

PURPOSE: To make constant the delay time up to the signal generation of a light pen by displaying the whole display part in specific color when reading a light signal displayed on the display part of a display unit.
CONSTITUTION: To change in color a checkered pattern displayed on display part 7a of display 7, color selection switches 17, and 17aW17f, etc., on operation panel 16 are operated and then light pen 15 is brought into contact with a checker to be changed in color, so that switch 15a of pen 15 turns on. After displaying one screen, central controller 8 makes sure of that and switches change-over circuit 13. In consequence, display controller 10 is supplied with an output signal from specific-color signal generating circuit 12 and display part 7a displays the specific color. A signal when the electron beam of display 7 scans part 15 enters address memory circuit 14 to correct the address as much as delay time and the checker assigned by pen 15 is changed in color, displaying a new mosaic pattern.
