Abstract
A color information input system in which handwritten information, such as letters or figures, etc., is input on an entry area by being converted into electrical signals. In order to display the handwritten information in color, different colored pens are stocked in pen stockers, each pen stocker having a detector which outputs a detection signal when the pen is removed from the corresponding pen stocker. The pen being used on the entry area is detected when it is removed from its pen stocker and color information is generated from the detection signal and passed on to a display unit.
