본 고안은 휴대용 또는 탁상용 전자계산기에 관한 것으로 더욱 상세히 설명하면 7세그멘트로 숫자가 표시되는 위 또는 아래에 또 다른 7세그멘트로 숫자를 이중으로 표시되도록 하여 전표숫자를 표시하기 위한 전자계산기에 관한 것이다.The present invention relates to a portable or desktop electronic calculator, and more particularly, to an electronic calculator for displaying a journal number by displaying a double number in another seven segments above or below a number displayed in seven segments.

종래의 탁상용 또는 휴대용 전자계산기에 있어서는 가감 승산되는 숫자만을 표시하도록 되어 있어서. 예를들어 전표등에 표시된 숫자를 더해가는 경우 몇장의 전표를 가산했는가를 확인할 수가 없는 불편이 있는바, 본 고안은 이와 같은 종래의 불편을 제거하기 위하여 숫자의 가산키이(+)를 누를때마다 보조표시부에 전표의 카운트 숫자가 표시되도록 하여 몇장째의 전표를 계산했는가를 확인할 수 있도록 한 것이다.In conventional desktop or portable electronic calculators, only numbers to be added or subtracted are displayed. For example, if you add the number displayed on the document, etc., it is inconvenient to check how many documents have been added. The present invention assists each time the number key (+) is pressed in order to eliminate the conventional inconvenience. The count number of the document is displayed on the display so that it is possible to check how many sheets were counted.

이하 본 고안을 첨부된 도면에 따라 상술한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

첨부된 제1도는 본 고안을 설명키 위한 사시도로 10은 휴대용 또는 탁상용 전자계산기로 키매트릭스(11)가 표시부(12)로 됨은 공지와 같은 것이며 다만 표시부(12)로 됨은 공지와 같은 것이며 다만 표시부(12)에 7세그멘트로 되는 가감승산 숫자표시부(12')이외에 +키이를 누를때마다 카운트하여 그 합산숫자를 표시하는 역시 7세그멘트로 되는 보조숫자 표시부(12")가 상측 또는 하측에 배설되었음을 보여주고 있다.1 is a perspective view for explaining the present invention, 10 is a portable or desktop electronic calculator, and the key matrix 11 is the same as that of the display unit 12. However, the display unit 12 is the same as that of the known unit. In addition to the 7-segment multiplication multiplication display unit 12 ', the sub-digit display unit 12 "which counts every time the + key is pressed and displays the total number is also arranged on the upper side or the lower side. Is showing.

이와같은 전기적 회로가 제2도에 표시되어 있다.Such an electrical circuit is shown in FIG.

제2도는 본 고안의 실시예를 나타내는 회로도로서, 키메트릭스(11)의 키이(l.2....0. +,-등)로 구성된입력회로부(lp)는 분주회로등으로 구성된 연산제어부(FC)에 연결됨과 아울러, +키의 동작신호를 카운트하기위한 카운트 출력회로부(OP')에 다이오드(D)를 통해 연결된다.2 is a circuit diagram showing an embodiment of the present invention, in which the input circuit part lp composed of the keys (1.2 .... 0. +,-, etc.) of the key metrics 11 is an arithmetic control part composed of a divider circuit or the like. In addition to the (FC), it is connected to the count output circuit unit OP 'for counting the operation signal of the + key through the diode (D).

상기 연산제어부(FC)는 계산기의 가산. 간산. 승산. 재산등을 행하는 연산부(OP)를 통하여 표시부(12')에 연결된다.The calculation control unit FC adds a calculator. Ganshan. multiplication. It is connected to the display part 12 'via the calculating part OP which performs property.

한편. 상기 카운트 출력회로부(OP')는 전표의 입력숫자를 카운트하여 표시하기 위한 제2의 표시부(12")에 연결되고. 상기 연산제어부(FC)와 연산부(OP)및 카운트 출력회로부(OP")에는 각각 전원부(POWER)가 연결된다.Meanwhile. The count output circuit section OP 'is connected to a second display section 12 "for counting and displaying the input number of the document. The calculation control section FC, the calculation section OP, and the count output circuit section OP". Each power supply unit is connected.

여기에서, 키이판(11)의 스위치 키이(1,2....0, +,-등)와 연결되는 입력회로부(Ip)의 출력은 분주 회로등을 갖춘 연산제어부(FC)와 7세그멘트등의 출력회로부(OP')를 통해 표시부(12)의 숫자표시부(12')에 디스플레이 될은 공지와 같은 것이며 본 고안에서 숫자를 더하기 위하여 +키이에 일방향성의 다이오드(D)를 통해 또 하나의 카운트 출력회로(OP,)에 입력시켜 카운트 되도록 되어 있어서 표시부(12)의 보조표시부(12')에 +키이를 누른 숫자만큼 표시되도록 하여서된 것이다.Here, the output of the input circuit part Ip connected to the switch keys (1, 2... 0, +,-, etc.) of the key plate 11 is an operation control unit FC with a frequency divider circuit and 7 segments. The display to be displayed on the numeric display portion 12 'of the display portion 12 through the output circuit portion OP' such as is the same as that known in the present invention and another one through the unidirectional diode D to the + key to add a number in the present invention. The count is inputted to the count output circuit OP, so as to be displayed by the number of the + keys pressed on the auxiliary display portion 12 'of the display portion 12.

상기와 같은 구성으로 된 것이므로 숫자를 가감 승산함은 공지와 같은 것이므로 이에 대한 설명은 생략하나 도시하지 않은 전표등에 기록된 숫자를 합산하는 경우 전표를 한장 한장 넘기면서 가산할때마다 +키이를 누르게 되는 것이므로 이때마다 +키이 신호는 일방향성 다이오드(D)를 통해 카운트 출력회로부(OP')에 입력되고, 이 입력신호는 1계단씩 업(LP)카운트되어 제2의 표시부(12")에 인가되므로 상기 제2의 표시부(12")에는 +키이를 누른 수 만큼의 합산숫자가 표시된다.Since it is configured as above, multiplying or multiplying the numbers is the same as the public notice, so the description thereof is omitted, but when adding the numbers recorded in a slip, etc. not shown, the key is pressed every time the count is added one by one. At this time, the + key signal is input to the count output circuit unit OP 'through the one-way diode D, and the input signal is counted up one LP and applied to the second display unit 12 ". The second display unit 12 "displays the total number of the number of pressing the + key.

따라서 전표를 다 계산한 숫자는 제2의 표시부(12")에 디스플레이 되어 나타나므로 전표의 숫자를 계산함으로서 총체적인 계산의 정확성을 기할 수 있을뿐 아니라 검산이 용이한다.Therefore, since the number of all the documents is displayed and displayed on the second display unit 12 ", the number of the documents can be calculated and the check can be easily performed.

즉, 전표의 매수와 보조표시부(12")에 나타난 숫자가 동일할때 총체적인 합산의 정확성을 확인할 수 있어서 수차례 반복하여 정확성을 확인하는 시간과 노력을 절감할 수 있는 실용적인 고안인 것이다.In other words, when the number of documents and the number shown on the auxiliary display unit 12 "are the same, it is possible to confirm the accuracy of the total sum, which is a practical design that can reduce the time and effort to check the accuracy by repeating several times.
