Claims

[Scope of utility model registration request]

Keyboard devices for devices that input or display graphical information, such as graphic displays, have a keyboard with a coordinate shift key, and key operations on this keyboard can be used to switch between normal mode, coordinate input mode, and coordinate setting mode. a coordinate conversion table that stores character codes and coordinate data in correspondence; and when the mode switching circuit is in the coordinate setting mode, the character code and numerical value input from the keyboard. Each key coordinate setting circuit stores data as a character code and coordinate data in the coordinate conversion table, and when the mode switching circuit is in the coordinate input mode, looks up the coordinate conversion table and converts the character code input from the keyboard. A keyboard device comprising: a coordinate conversion circuit that converts into coordinate data and outputs the converted data.
