Abstract

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a programmable keyboard device for formatting and arranging keys so as to have a form, key location, and function suitable for an application program used in a computer system. Since the characteristics and functions of the standardization are standardized, when operating a general program using only the standardized functions of the keys, users can simply learn how to use the general program and use it, but the application has special functions other than the standardized functions of the keys. When operating a program, the user has to learn a key to command a special function, which has caused a lot of difficulties in the operation of the application program. Each application has a frequently used key and a key that is not used at all. On the board device Since many keys with prescribed functions are located at the standardized size, many keys are not used according to the program, which makes it difficult to operate the keyboard device, and frequently used keys are compared to the frequency of use. Its size was small and easily damaged.

The present invention relates to a central processing unit for controlling the overall operation of a keyboard device, a keypad provided with input / output elements and teaching elements, a driving circuit portion for applying driving sinhol to the input / output elements of the keypad, and a keypad according to an input keyboard program. A display control unit for controlling a display element to display a key, and a scan code generator for outputting a scan code signal for a key signal output from an input / output device according to an input scan code program by pressing a key displayed on a display element of a keypad In addition, it displays the function of the displayed keys together with the general and special function keys used according to the keyboard program for the program used in the computer system, and displays the key size differently according to the frequency of use of each key. Scan code program for key code output from I / O device By printing in accordance it may also simply be cooked without a command key of the special function to be used if a program with a special function, and simplifies operation of the keyboard apparatus, so that the frequency learning p damage to the keys used.
