Description

전자식 타자기의 계산방법Calculation method of electronic typewriter

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음As this is a public information case, the full text was not included.

제1도는 본 발명이 적용되는 시스템 블럭도.1 is a system block diagram to which the present invention is applied.

Claims (1)

전자식 타자기에 있어서, 시스템 초기화 과정과, 키스캔 및 분석하여 코드키와 C키 동시 입력이면 계산기능 플래그를 세트시키고 코드키와 D키 동시 입력이면 계산 기능 플래그를 클리어시킨후 루핑하는 과정과, 코드키와 C키 및 코드키와 D키의 동시 입력이 아닐시 계산 기능 플래그 세트 여부를 확인하는 과정과, 계산 기능 플래그 세트시 계산 기능에 적합한 키인지 여부에 따라 계산 기능을 수행하거나 에러 메세지를 발생하며 계산 기능 플래그 세트 상태가 아닐시 해당키 기능을 수행하는 과정과, 해당키 기능 혹은 계산기 기능 수행후 디스플레이 및 인자 수행 여부를 확인하여 처리하는 과정으로 이루어짐을 특징으로 하는 계산방법.In an electronic typewriter, a system initialization process, a key scan, and an analysis are performed to set a calculation function flag if the code key and the C key are simultaneously input, and to loop after clearing the calculation function flag if the code key and the D key are simultaneously input, When the key, C key, code key, and D key are not input simultaneously, the process of checking whether or not the calculation function flag is set and performing the calculation function or generating an error message depending on whether the key is suitable for the calculation function when the calculation function flag is set And a process of performing a corresponding key function when the calculation function flag is not in a set state, and a process of confirming and processing whether a display and a factor are performed after performing a corresponding key function or a calculator function. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
