건전지 교체시 계수표시장치의 기능선택회로Function selection circuit of counting device when battery is replaced

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

제3도는 본 발명에 따른 기능선택회로의 개략도.3 is a schematic diagram of a function selection circuit according to the present invention.

제4도는 본 발명에 따른 계수표시장치의 기능선택회로에 있어 기능선택 및 숫자 변경방법의 처리 순서를 나타낸 흐름도.4 is a flowchart showing a processing procedure of a function selection and number changing method in the function selection circuit of the counting display device according to the present invention;

* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

10 : 스위치 입력부 20 : 기능선택 펄스발생부10: switch input part 20: function selection pulse generator

30 : 자동기능 선택 펄스발생부30: automatic function selection pulse generator

Claims (1)

스위치 입력부(10)와 접속되어 있는 기능선택 펄스발생부(20)에 건전지 교체시 발생되는 POR신호가 인가되어 시스템의 기능선택단자에 클리어 신호를 제공하는 계수표시장치에 있어서, 상기의 POR신호를 입력할때 하이레벨신호를 기능선택 펄스발생부(20)에 제공하는 자동기능선택 펄스발생부(30)를 연결하여서, 상기 기능선택 펄스발행부(20)에서 기능선택펄스를 발생하여 기능선택단자에 제공함을 특징으로 하는 건전지 교체시 계수표시장치의 기능선택회로.In the counting display device which provides a clear signal to a function selection terminal of the system by applying a POR signal generated when a battery is replaced to the function selection pulse generator 20 connected to the switch input unit 10, the POR signal is supplied. By connecting the automatic function selection pulse generator 30 which provides a high level signal to the function selection pulse generator 20 at the time of input, the function selection pulse is generated by the function selection pulse issuing unit 20 to generate a function selection pulse. Function selection circuit of the counting display device when replacing the battery, characterized in that provided to. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
