Description

스케너가 부착된 잉크젯 프린터의 퀵 스켄 장치Quick Scan Unit of Inkjet Printer with Scanner

본 발명은 스케너가 부착된 잉크젯 프린터에 관한 것으로, 특히 용지 이송경로를 절환하기 위한 서브 가이드를 부가하여 용지 이송 경로를 분리함으로서 고 품질의 이미지 데이터를 스케닝하기 위한 잉크젯 프린터의 퀵 스켄(Quick Scan) 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inkjet printer with a scanner, and in particular, a quick scan of an inkjet printer for scanning high quality image data by separating a paper conveying path by adding a sub guide for switching the paper conveying path. Relates to a device.

일반적으로, 1 페이지 데이터 중 일부만 선택하여 스케닝을 하기 위한 퀵 스켄 기능(Quick Scan)은 2회로 나누어서 스켄 동작을 하게 되며 1회 스켄 동작시에는 고속으로 드레프트(Draft)한 스케닝을 하고, 사용자가 원하는 위치를 지정하면 2회 동작시에는 필요한 부분만 고품질의 스켄 동작을 하게 되며, 매회 스켄 동작시에는 용지의 이송 동작을 수반한다.In general, the quick scan function for scanning by selecting only a part of one page data is divided into two times, and the scan operation is performed at high speed during one scan operation. If a desired position is specified, only a necessary portion is scanned in high quality in two operations, and every time a scanning operation involves conveying paper.

이러한 동작을 구현하기 위하여 종래에는 1회 스켄 동작 완료시 이송된 용지를 배지시켜서 사용자가 2회 스켄 동작을 위하여 용지를 프린터 또는 스케너에 재공급 시키는 리셋(Reset) 방식과 1 회 스켄 동작 완료시 용지를 역이송 동작을 시켜서 스켄 동작 이전의 위치로 보낸 후 2회 스켄 동작을 실행하는 리 스타트(Re-Start) 방식이 있으며, 상기 리 스타트(Re-Start) 방식의 경우 1회 스켄 동작시 용지의 후단이 픽업 로울러로부터 이탈됨으로서 역이송 동작시 용지 걸림 현상을 방지하기 위하여 용지의 후단을 연장시키기 위한 용지 캐리어를 별도로 구비하여야 한다.In order to realize such an operation, a reset method for discharging the conveyed paper at the completion of one scan operation and reloading the paper to a printer or a scanner for two scan operations and a paper at the completion of one scan operation are conventionally performed. There is a re-start method that performs the reverse scan operation and sends it to the position before the scan operation, and then executes two scan operations. In the case of the re-start method, Since the rear end is separated from the pickup roller, a paper carrier for extending the rear end of the paper must be separately provided to prevent the paper jam phenomenon during the reverse feed operation.

이와 같이 종래의 선행 기술에 의하면, 리셋(Reset) 방식과 용지 캐리어를 사용하느 리 스타트(Re-Start) 방식 2가지 모두 불편하지만, 특히 리셋 방식(Reset)은 1 회 스켄 동작 완료 후 배출된 용지를 사용자가 수동으로 재 급지하여야 하므로 그 급지 동작에 따른 스켄 위치 오차가 발생할 수 있고, 리스타트(Re-Start) 방식은 사용자가 용지 캐리어를 별도로 구비하여 보관하여야 하므로 보관상의 분실 우려 및 비용이 증대되는 문제점이 있다.As described above, according to the conventional prior art, both the reset method and the re-start method using the paper carrier are inconvenient, but the reset method is particularly used for ejecting paper after one scan operation is completed. The user may need to refeed the paper manually, so scan position error may occur due to the feeding operation.In case of the Re-Start method, the user needs to keep the paper carrier separately and increase the risk of storage loss and increase the cost. There is a problem.

본 발명은 위치 오차를 감소시키고, 용지 케리어를 사용하지 않는 리 스타트 방식을 사용하여, 용지의 정이송과 역이송의 이송 통로를 분리시켜 용지 캐리어 구입 및 보관에 따른 불편함을 해소하고자 하는데 그 목적이 있다.The present invention is to reduce the position error, by using a restart method that does not use a paper carrier, to eliminate the inconvenience of the paper carrier purchase and storage by separating the transfer path of the forward and reverse feed of the paper There is this.

이와 같은 목적을 구현하기 위하여, 페이퍼 트라이 본체와, 스케닝 또는 프린팅할 용지를 보관하는 장치인 페이퍼 플레이트와, 상기 페이퍼 플레이트에 보관된 용지를 피드 로울러와 핀치 로울러의 접점 위치까지 이송시키는 픽업 로울러와, 솔레노이드의 동작에 따라 용지 이송 경로를 절환하는 서브 가이드와, 사용자에 절환 명령에 의해 이송 경로를 절환하는 서브 가이드의 동력원인 솔레노이드와, 상기 페이퍼 트라이로부터 이송되어 온 용지를 피드 로울러 위치로 가이드하기 위한 용지 가이드와, 용지 이송 동작의 주 동력원인 피드 로울러와, 용지를 피드 로울러 방향으로 가압하여 피드 로울러와 용지 사이의 마찰력을 유발시키기 위한 아이들 로울러인 핀치 로울러와, 용지상의 이미지 데이터를 읽어 들이기 위한 스케너 헤드로 구성된 특징이 있다.In order to achieve the above object, a paper tri main body, a paper plate which is a device for storing paper to be scanned or printed, a pickup roller for transferring the paper stored in the paper plate to a contact point of a feed roller and a pinch roller, A sub guide for switching the paper feed path according to the operation of the solenoid, a solenoid that is a power source of the sub guide for switching the feed path by a switching command to the user, and a guide for guiding the paper conveyed from the paper try to the feed roller position.

도 1 및 도 2는 본 발명의 일 실시에 따른 예를 나타낸 것으로, 페이퍼 트라이 본체(10)와, 스케닝 또는 프린팅할 용지를 보관하는 장치인 페이퍼 플레이트(11)와, 상기 페이퍼 플레이트(11)에 보관된 용지를 피드 로울러와 핀치 로울러의 접점 위치까지 이송시키는 픽업 로울러(12)와, 솔레노이드의 동작에 따라 용지 이송 경로를 절환시키는 서브 가이드(13)와, 사용자에 절환 명령에 의해 용지 이송 경로를 절환하는 서브 가이드(13)의 원동력인 솔레노이드(14)와, 상기 페이퍼 트라이(10)로부터 이송되어 온 용지를 피드 로울러 위치로 가이드하기 위한 용지 가이드(15)와, 용지 이송 동작의 주 동력원인 피드 로울러(16)와, 용지를 피드 로울러 방향으로 가압하여 피드 로울러와 용지 사이의 마찰력을 유발시키기 위한 아이들 로울러인 핀치 로울러(18)와, 용지상의 이미지 데이터를 읽어들이기 위한 스케너 헤드(18)로 구성되어 있다.1 and 2 illustrate an example according to an embodiment of the present invention, which includes a paper tri main body 10, a paper plate 11, which is a device for storing paper to be scanned or printed, and a paper plate 11. A pickup roller 12 for transferring the stored paper to the contact point between the feed roller and the pinch roller, a sub guide 13 for switching the paper feed path according to the operation of the solenoid, and a paper feed path by a switching command to the user. The solenoid 14 which is the driving force of the sub-guide 13 to switch, the paper guide 15 for guiding the paper conveyed from the paper try 10 to a feed roller position, and the feed which is a main power source of a paper conveying operation | movement The roller 16 and the pinch roller 18, which is an idle roller for pressing the paper in the feed roller direction to induce friction between the feed roller and the paper, It consists of the scanner head 18 for reading image data.

이와 같은 구성에 따른 동작을 첨부된 도면 도 1 내지 도 2를 참조하여 설명하면 다음과 같다.An operation according to such a configuration will be described with reference to FIGS. 1 to 2 as follows.

한 페이지의 이미지 데이터중 일부분만 선택하여 스케닝을 하기 위하여 첫 번째 스켄 동작시 우선 픽업 로울러(12)가 페이퍼 플래이트(11) 상에 있는 용지의 선단을 이송 경로 A를 따라 피드 로울러(16) 위치까지 이송시키면 피드 로울러(16)가 용지를 일정량 만큼씩 스케너 헤드(18) 방향으로 이송시키면서 스케너 헤드(18)에 의해 용지상의 이미지 데이터를 읽어 들인다.In order to select and scan only a portion of the image data of one page, the pickup roller 12 first moves the leading edge of the paper on the paper plate 11 to the position of the feed roller 16 along the feed path A in order to scan. When the feed is carried out, the feed roller 16 reads the image data on the paper by the scanner head 18 while feeding the paper in the direction of the scanner head 18 by a predetermined amount.

이러한 스켄 동작은 용지의 후단이 피드 로울러(16)의 위치에 도달할 때까지계속되고, 첫 번째 스켄 동작이므로 용지는 고속으로 이송시키고 스케닝 양도 일정량 만큼 스킵(Skip)하면서 진행하게 된다.This scan operation continues until the rear end of the paper reaches the position of the feed roller 16. Since the first scan operation, the paper is conveyed at high speed and the scanning amount is skipped by a predetermined amount.

이때, 용지의 이송 경로를 절환하기 위하여 솔레노이드 작동하여 도 1에서와 같이 용지 이송 결로 절환 장치인 서브 가이드(13)가 용지 이송 경로 밑으로 내려와 있다.At this time, the solenoid is operated to switch the paper conveying path, and as shown in FIG. 1, the sub guide 13, which is a paper conveying condensation switching device, descends under the paper conveying path.

이상과 같이 첫 번째 스켄 동작이 완료되면, 드레프트(Draft)하게 스케닝된 이미지 데이터는 컴퓨터(미 도시됨)로 보내지고 사용자는 이미지 상에서 필요한 부분을 지정하여 스켄 명령을 주면 솔레노이드(Solenoide)(14)가 작동되어 도 2에서와 같이 서브 가이드(13)의 위치가 변경된다.As described above, when the first scan operation is completed, draft-scanned image data is sent to a computer (not shown), and the user specifies a required portion of the image and gives a scan command to the solenoide (14). ) Is operated to change the position of the sub guide 13 as shown in FIG.

따라서, 피드 로울러(16)를 역회전시키면 용지는 이송 경로 B를 따라서 역이송하게 된다.Therefore, when the feed roller 16 is rotated in reverse, the paper is conveyed back along the transfer path B. FIG.

상기와 같이 피드 로울러(16)가 역회전되어 용지의 선단이 피드 로울러(16)의 위치에 도달하면 역이송 동작을 정지하고, 피드 로울러(16)를 정회전시킴으로서 용지는 이송 경로 C를 따라서 정이송되고 두번째 스켄 동작, 즉 필요한 부분만 스켄 동작을 진행하게 된다.As described above, when the feed roller 16 is reversely rotated and the leading edge of the paper reaches the position of the feed roller 16, the reverse feed operation is stopped, and the paper is rotated forward along the feed path C by rotating the feed roller 16 forward. It is transferred and the second scan operation, that is, only the necessary parts are scanned.

이와 같이 두번째 스켄 동작은 사용자가 지정하지 않은 위치에서는 스케닝을 하지 않고 용지를 고속으로 이송시키며, 지정한 위치에서는 정상적으로 스케닝 동작을 진행한다.As described above, the second scan operation transfers the paper at high speed without scanning at a position not specified by the user, and performs the scanning operation normally at the designated position.

이상에서 설명한 바와 같이, 용지를 필요한 위치까지 자동으로 정 또는 역 방향으로 이송시킴으로서, 별도의 용지 캐리어 구입에 따른 비용이 감소되고 아울러 보관상의 불편함이 해소되는 효과가 있다As described above, by automatically transporting the paper to the required position in the forward or reverse direction, the cost of purchasing a separate paper carrier is reduced and the inconvenience of storage is eliminated.
