Abstract

PURPOSE: To enable the operation of the liquid crystal type electronic desk computer even at night or in the dark place by provinding the illumination function and using the fluorescent paints to the key dispaly characters or patterns.
CONSTITUTION: The electronic desk computer is enclosed into apperance case 1 made of the plastic resin, metal and other materials, and the characters and patterns of external input key 2 are displayed via the fluorescent paints. Liquid crystal display device 3 contains the liquid crystal enclosed between the lower panel glasses, and electronic circuit part 4 including the IC supplies and calculates the signals sent from key 2 via conducting rubber 5 to display it on liquid crystal display device 3. Cell 6 uses the button-type miniature cell. And lamp 7 is located just beside to reflecting plate 8. Owing to the illumination of lamp 7, the characters and patterns displayed to key 2 can be recognized clearly even in the dark, thus ensuring the operation of the electronic desk computer even at night.
