Abstract

1. 청구범위에 기재된 발명이 속한 기술분야1. TECHNICAL FIELD OF THE INVENTION

프린터의 동작상태를 외부에서 테스트하는 장치에 관한 것이다.The present invention relates to an apparatus for externally testing the operating state of a printer.

2. 발명이 해결하고자 하는 기술적 과제2. Technical problem to be solved by the invention

PC를 사용치 않고서도 프린터의 동작을 외부에서 테스트하여 테스트에 따른 비용과 공간 및 동작 테스트시간을 감소시키며 테스트를 의해 별도의 외부 전원을 필요로 하지 않는 프린터의 동작 테스트장치를 제공한다.By testing the operation of the printer externally without using a PC, it reduces the cost, space and operation test time according to the test, and provides a test operation device for the printer that does not require a separate external power supply by the test.

3. 발명의 해결방법의 요지3. Summary of Solution to Invention

프린터의 동작을 테스트하기 위한 테스트 프로그램을 저장하고 있는 메모리와, 프린터에 대한 테스트를 지시하기 위한 키들을 구비하는 조작판넬과, 조작판넬로부터의 키입력을 버퍼링하는 버퍼와, 프린터와 규정된 제어 신호들과 데이타를 송수신하기 위한 전송 경로를 제공하는 연결수단과, 버퍼를 통한 키입력에 응답하여 메모리의 테스트 프로그램에 따라 연결수단을 통해 데이타를 프린터로 전송하여 프린터의 동작을 테스트하는 제어수단과, 연결수단과 제어수단 사이에 접속되어 프린터와 제어신호들을 송수신하며 프린터로 전송되는 데이타에 대한 인터페이스를 제공하는 인터페이스회로를 구비한다.A memory storing a test program for testing the operation of the printer, an operation panel having keys for instructing a test of the printer, a buffer for buffering key input from the operation panel, a printer and prescribed control signals Connection means for providing a transmission path for transmitting and receiving data to and from the data; An interface circuit is connected between the connecting means and the control means to transmit and receive a printer and control signals and to provide an interface for data transmitted to the printer.

4. 발명의 중요한 용도4. Important uses of the invention

프린터의 동작을 PC를 사용치 않고 외부에서 테스트하는데 이용한다.The printer's operation is used for external testing without using a PC.
