Claims (1)

일반모드의 키에이타를 저장하는 제1데이타영역 및 확장 모드에서 일반모드의 키와 동일한 기능을 수행하는 키데이타를 저장하는 제2데이타 영역을 갖는 제1메모리와, 확장모드에서 일반모드의 키데이타의 다른 기능을 수행하는 키 데이타를 저장하는 제2메모리와, 확장키를 구비한 키보드로 구성된 금전 등록 시스템에 있어서, 임의 키입력시 확장모드에서 키입력인가 검사하며, 확장모드에서의 키입력일시 해당키 표시 및 확장플래그를 세트하고, 해당키 값을 디코딩하는 제1과정과, 상기 제1과정 수행후 확장기능인가 검사하며, 확장기능일시 제2메모리의 해당키 내용으로 변경하여 기능을 수행하는 제2과정과, 상기 제2과정 수행후 확장플래그 세트상태인가 검사하며, 아닐시 종료하는 제3과정과, 상기 제3과정에서 확장플래그 세트상태일시 플래그를 리세트시키고 제1메모리로 점프하며, 종료하는 제4과정과,제1메모리로 점프하며, 종료하는 제4과정과, 상기 제2과정에서 확장기능이 아닐시 제1메모리의 제2데이타 영역으로 점프하여 해당키의 변경기능을 수행한 후 확장플래그를 리세트시키고 상기 제3과정으로 진행하는 제5과정과, 상기 제1과정에서 일반모드일시 제1메모리의 제1데이타 영역에 따른 해당 키기능을 수행하고 상기 제3과정으로 진행하는 제6과정으로 이루어짐을 특징으로 하는 키 확장방법.A first memory having a first data area for storing key data in the normal mode and a second data area for storing key data performing the same function as a key in the normal mode in the extended mode, and key data in the normal mode in the extended mode A cash register system comprising a second memory for storing key data for performing other functions, and a keyboard having an extended key, wherein the random key input is checked for key input in the extended mode, and the date and time for the key input in the extended mode. Sets the corresponding key display and expansion flag, and checks whether the first process decodes the corresponding key value and whether the extended function is performed after performing the first process, and changes the extended function to the corresponding key contents of the second memory to perform the function. And a third step of checking whether or not the extended flag set state is executed after performing the second step, and ending the non-expanded flag in the third step; A fourth process of resetting and jumping to the first memory and terminating; a fourth process of jumping to the first memory and terminating; and a second data area of the first memory when the second process is not an extended function. After the jump function is performed to change the corresponding key, the fifth step of resetting the extension flag and proceeding to the third step and the corresponding key function according to the first data area of the first memory in the general mode during the first step are performed. And a sixth step of proceeding to the third step. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
