프린터의 보드접속 구조체Board Connection Structure of Printer

본 발명은 프린터의 보드 접속구조체에 관한 것으로서, 상세하게는 업그레이드를 위한 회로기판의 교체 및 그 추가설치가 용이한 접속구조를 갖는 프린터의 보드 접속구조체에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board connection structure of a printer, and more particularly, to a board connection structure of a printer having a connection structure that is easy to replace and additionally install a circuit board for upgrading.

프린터는 인쇄장치의 하나로서, 전자사진방식인 경우에는 노광에 의해 정전 잠상이 형성되어 있는 감광매체에 고체상태의 현상물질인 토너 또는 액체상태의 잉크를 분사시켜 화상을 형성시킨 후, 그 감광 매체와 접촉되어 회전하는 롤러 상이로 용지 카세트에 적재된 용지를 급지하여 통과시킴으로써 원하는 화상을 인쇄할 수 있도록 되어있다.The printer is one of printing apparatuses. In the electrophotographic method, an image is formed by spraying a toner or a liquid ink in a solid developing material onto a photosensitive medium on which an electrostatic latent image is formed by exposure to form an image. The desired image can be printed by feeding and passing the paper loaded in the paper cassette with the rollers rotating in contact with each other.

도 1에는 이러한 종래의 프린터와 그 일부를 부분확대해 보인 사시도가 도시되어 있다.Figure 1 shows a perspective view of a partial enlarged view of such a conventional printer.

도면을 참조하면, 외부장치 예컨데 사용자 컴퓨터와의 직접 또는 넥트웍망과의 접속용 콘넥터들(13)이 그 일측에 설치되어 있는 메인회로기판(12)이 프린터(10) 본체(11)의 후측에 설치되어 있다.Referring to the drawings, an external device such as a main circuit board 12 having connectors 13 for direct connection with a user computer or a network for a network is installed on one side thereof, and the rear side of the main body 11 of the printer 10. Installed in

메인회로기판(12)상에는 시스템전반을 제어하는 프린터 콘트롤부(14)를 이루는 부품요소들이 대부분의 영역을 차지하면서 실장되어 있고, 메모리확장용등 기능추가를 위한 다수의 확장슬롯(15)에 보조회로기판(16)이 설치되어 있다. 이와 같은 종래의 보드구조에 의하면 메모리확장 또는 LAN카드 등 프린터(10)의 사용기능을 확장시키고 할 때는 그에 대응하는 보조회로기판(16)을 메인회로기판(12)상에 설치된 확장슬롯(15)에 장착시켜 사용할 수 있지만, 인쇄처리속도에 영향을 미치는 중앙처리장치(CPU)의 데이터 처리속도향상을 포함한 전반적인 프린터 콘트롤러부(14) 자체를 업그레이하고자 할 때는 메인회로기판(12) 전체를 교체해야만 한다. 이러한 메인회로기판(12) 전체교체작업은 본체를 분해하는 작업이 동반되어야 하기 때문에 교체작업이 번거롭고, 확장슬롯(15)등 프린터 콘트롤러부(14)와 관계없는 부분을 제외한 필요요소만의 교체작업이 불가능하여 불필요한 자원손실에 대한 문제점도 안고 있다.On the main circuit board 12, component elements constituting the printer control unit 14 for controlling the entire system are mounted while occupying most of the area, and are supported by a plurality of expansion slots 15 for adding functions such as memory expansion. The circuit board 16 is provided. According to the conventional board structure as described above, when expanding the use function of the printer 10 such as memory expansion or LAN card, the auxiliary circuit board 16 corresponding to the expansion slot 15 is installed on the main circuit board 12. Can be used for the purpose of upgrading the overall printer controller 14 itself, including the improvement of the data processing speed of the CPU, which affects the print processing speed, the entire main circuit board 12 must be replaced. do. Since the replacement of the main circuit board 12 must be accompanied by the work of disassembling the main body, the replacement work is cumbersome, and only the necessary elements except for parts not related to the printer controller 14 such as the expansion slot 15 are replaced. This is not possible, and there is a problem of unnecessary resource loss.

특히, 인쇄품질향상과 인쇄처리속도 증진을 위한 꾸준한 기술개발 및 멀티미디어시대에 발맞춰 단순 인쇄기능외에 사용자 편리를 도모하는 부가 서비스 기능등의 추가기능설치 요구등에 따른 업그레이드 요구시기가 갈수록 짧아지는 추세여서 프린터 콘트롤러부(14)를 포함한 임의의 회로기판에 대한 업그레이드 작업이 용이한 보드접속구조체에 대한 필요성이 강조되고 있다.In particular, due to the steady development of technology to improve print quality and speed of print processing, and the demand for the installation of additional functions such as additional service functions that facilitate user convenience in addition to the simple printing function, the time for upgrading is getting shorter. There is a need for a board connection structure that is easy to upgrade to any circuit board including the printer controller unit 14.

본 발명은 상기와 같은 문제점을 개선하기 위하여 창안된 것으로서, 업그레이드와 관련된 프린터의 제반 회로기판요소들의 추가장착 및 그 교체를 위한 탈착이 기능블록단위로 용이하게 이루어 질 수 있는 프린터의 보드접속 구조체를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made to improve the above problems, and provides a board connection structure of a printer that can be easily attached and detached for the additional circuit board elements of the printer related to the upgrade and the replacement thereof in functional block units. The purpose is to provide.
