PURPOSE:To perform the dynamic comparison between each function key and a key name showing the function allotted to each key without using a work mat, etc., by providing a dynamic display function applying a controllable flat plate type display device. CONSTITUTION:A keyboard 310 contains function keys 311-318 having hynamic display functions applying a controllable flat plate type display device in addition to normal keys. A CPU40 converts the parameter designated by a program 412 into a style that can be decoded by a keyboard controller 320 is response to an IOCS411 when it executes an application program 412. This converted parameter is transferred to the controller 320. The controller 320 displays a designated character train of a designated one of keys 311-318 based on the transferred data via a display control line 350. In such a way, the function key itself is formed with a display. This eliminates the use of a work mat, etc. and ensures a dynamic display.
