Description

타자기를 이용한 계산기능 수행방법How to perform calculation function using typewriter

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명을 적용한 전자식 타자기의 개략적인 블록 구성도,1 is a schematic block diagram of an electronic typewriter to which the present invention is applied;

제2도는 본 발명의 타자기를 이용한 계산기능 수행방법을 설명하기 위한 플로우 챠트.2 is a flowchart illustrating a method of performing a calculation function using a typewriter of the present invention.

Claims (5)

타자기의 키보드(2)로부터 중앙처리장치(1)에 숫자데이타가 입력되면 그 숫자데이타를 버퍼(A)에 저장시키고 타이핑한 후 숫자데이타에 연이어서 연산(+,-,*,/)데이타가 입력되면 해당 연산표시 플래그를 세트시키고 버퍼(A)의 숫자데이타를 10진수로 변환하여 버퍼(A′)에 저장시킨 후 버퍼(A)를 클리어시켜 피연산수를 구성하는 과정과, 피연산수 구성에 이어서 숫자데이타 입력되면 그 숫자데이타를 버퍼(A)에 저장시키고 타이핑한후 숫자데이타를 연이어서 "="데이타가 입력되면 버퍼(A)의 숫자데이타를 10진수로 변환하여 버퍼(B′)에 저장시킨 후 버퍼(A)를 클리어시켜 연산수를 구성하는 과정과, 연산수 구성에 이어서 버퍼(A′,B′)의 내용을 연산표시 플래그에 따라 계산하고 그 결과를 타이핑함과 동시에 메모리(9)에 저장시킨 후 종료하는 연산 및 출력 과정으로 이루어진 타자기를 이용한 계간기능 수행방법.When numeric data is input from the keyboard 2 of the typewriter to the central processing unit 1, the numeric data is stored in the buffer (A), typed, followed by the numeric data, and the operation (+,-, *, /) data is displayed. If input, set the operation display flag, convert the numeric data of the buffer A into decimal number, store it in the buffer A ', and clear the buffer A to configure the operand, and After the configuration, if numeric data is inputted, the numeric data is stored in the buffer (A) and typed, followed by the numeric data. If "=" data is inputted, the numeric data of the buffer (A) is converted to decimal number and the buffer (B ' ), The buffer A is cleared to form the number of operations, and after the composition of the number of calculations, the contents of the buffers A 'and B' are calculated according to the operation display flag and the results are typed. Operation and output which are saved after saving to memory 9 Method of performing quarterly functions using a typewriter consisting of a process. 제1항에 있어서, 피연산수를 구성하는 과정에서연산표시 플래그가 세트되지 않은 경우 또는 버퍼(A′)플래그가 세트된 경우에는 해당 데이터를 타이핑함을 특징으로 하는 타자기를 이용한 계산기능 수행방법.The method of claim 1, wherein when the operation display flag is not set or when the buffer A 'flag is set, the corresponding data is typed. . 제1항에 있어서, 피연산수를 구성하는 과정에서 버퍼(A)에 데이터가 존재하지 않는 경우에는 에러 발생으로 판별하여 버퍼 및 플래그를 클리어시킨 후 종료함을 특징으로 하는 타자기를 이용한 계산기능 수행방법.The calculation function according to claim 1, wherein when data is not present in the buffer A in the process of configuring the operand, an error is determined and the buffer and flag are cleared and then terminated. Way. 제1항에 있어서, 연산수를 구성하는 과정에서 "="데이타가 입력되지 않거나 또는 버퍼(A)에 데이터가 존재하지 않거나 또는 버퍼(A′)플래그가 세트되지 않은 경우에는 공히 에러 발생으로 판별하여 버퍼 및 플래그를 클리어시킨 후 종료함을 특징으로 하는 타자기를 이용한 계산기능 수행방법.The method of claim 1, wherein in the process of constructing the number of operations, if "=" no data is input, no data exists in the buffer A, or no buffer A 'flag is set, it is determined as an error occurrence. Performing a calculation function using a typewriter, wherein the buffer and flag are cleared and then terminated. 제1항에 있어서, 피연산수를 구성하는 과정의 수행전에 키보드(2)상에 약정된 키이에 따른 모드 온,오프 판별을 수행함을 특징으로 하는 타자기를 이용한 계산기능 수행방법.2. A method according to claim 1, characterized in that mode on and off discrimination is performed according to the key promised on the keyboard (2) before performing the process of constructing the operand. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
