Abstract
본 발명은 모터로 구동하는 카드 리더기에서 카드의 정지위치를 정밀제어하기 위한 장치에 관한 것으로 특지 직류 모터의 속도를 제어하기 위한 카드 정지위치 정밀제어장치를 설치하여 모터의 회전속도를 조절할 수 있도록 구성하여 카드의 정지위치를 정밀하게 제어할 수 있도록 한 모터구동형 카드 리더기에서의 카드 정지위치 정밀제어장치에 관한 것으로서 모터구동형 카드 리더기에 있어서, 마이크로 프로세서로부터 출력된 제어신호를 입력하기 위한 제어신호 입력단자와 상기 제어신호 입력단자로부터 입력된 제어신호와 전원공급단(A2)을 통해 공급된 기준전압을 분압하여 내부기준레벨을 설정하는 마이크로 콘트롤러 및 상기 마이크로 콘트롤러로부터 출력된 내부기준레벨을 근거로 후술되어질 직류 모터를 구동하기 위한 모터의 구동전압을 공급하는 모터 구동부를 포함하여 구성된 것을 특징으로 한다.The present invention relates to a device for precisely controlling the stop position of a card in a card reader driven by a motor, and is configured to adjust the rotational speed of the motor by installing a card stop position precision control device for controlling the speed of a special DC motor. The present invention relates to a precise control device for a card stop position in a motor-driven card reader capable of precisely controlling the stop position of a card. The motor-driven card reader includes a control signal for inputting a control signal output from a microprocessor. On the basis of the microcontroller for setting an internal reference level by dividing the control signal input from the input terminal and the control signal input terminal and the reference voltage supplied through the power supply terminal A 2 and the internal reference level output from the microcontroller. Before driving the motor for driving the DC motor to be described later By a motor driving unit for supplying characterized in that configured.
