The paper feeding unit 11 is hinged to one end of the printing machine frame 60 and elastically biased in one rotational direction. The paper feeding unit 11 is a manual paper feeding place where a separate paper cartridge is not mounted. The paper feed sensor 13 detects the presence or absence of paper in the paper feeder 11 by the contact with the loaded paper. The pick-up means 30 includes a pick-up roller 35 and a pick-up clutch 35 for selectively transferring power of the driving source 20 transmitted through the relay gears 33 to the pick-up roller 31.

상기 레지스트레이션수단(50)은 상기 가이드플레이트(41)를 통해 가이드된 용지 선단의 위치를 감지하는 레지스트레이션센서(51)와, 상기 레지스트레이션센서(51)를 통과한 인쇄용지의 선단스큐 조절 및 전사유니트(80)를 통해 전사된 화상과 용지를 매칭하기 위한 선단정렬롤러(53)와, 상기 구동원(20)에서 제공되는 동력을 선택적으로 상기 선단정렬롤러(53)에 전달하는 레지스트레이션클러치(55)를 포함한다.The registration means 50 is a registration sensor 51 for detecting the position of the leading edge of the paper guided through the guide plate 41, and the end skew adjustment and transfer unit of the printing paper passed through the registration sensor 51 ( A front end alignment roller 53 for matching the image and the paper transferred through 80, and a registration clutch 55 for selectively transferring the power provided from the driving source 20 to the front end alignment roller 53. do.

상기한 바와 같이 구성된 장치에 있어서, 동작을 살펴보면 다음과 같다.In the device configured as described above, the operation is as follows.

급지부(11)에 인쇄용지(P)가 급지된 상태에서 수동급지모드에서 인쇄가 시작되면 구동원(20)이 구동하게 된다. 이 구동원(20)에서 제공되는 동력은 가이드롤러(45), 픽업클러치(35) 및, 레지스트레이션클러치(55)에 전달된다. 여기서, 상기 가이드롤러(45)는 상기 구동원(20)에 직접 연결되어 구동원(20)의 구동시 항상 구동되며, 상기 픽업클러치(35) 및 레지스트레이션클러치(55)는 구동원(20)의 구동시 그 자체의 온(ON)/오프(OFF)에 따라 선택적으로 구동된다.When printing is started in the manual feed mode while the printing paper P is fed to the paper feeding unit 11, the driving source 20 is driven. Power supplied from this drive source 20 is transmitted to the guide roller 45, the pickup clutch 35, and the registration clutch 55. Here, the guide roller 45 is directly connected to the drive source 20 is always driven when the drive source 20 is driven, the pickup clutch 35 and the registration clutch 55 is driven when the drive source 20 is driven. It is selectively driven according to its ON / OFF.

따라서, 인쇄기의 현상유니트에서 전달된 신호에 의해 상기 픽업클러치(35)가 온(ON)되고, 이에 따라 픽업롤러(31)가 동작하여 상기 급지부(11)에 장착된 용지가 급지된다. 한편, 상기 레지스트레이션클러치(55)는 상기 픽업클러치(35)의 온 상태 이후, 소정 시간 예컨대 3.33초 후에 온 되어 선단정렬롤러(53)를 구동하여 용지를 전사유니트(80) 쪽으로 전달한다. 이와 같이 시간차를 두고 레지스트레이션클러치(55)를 구동하는 이유는 급지된 용지의 선단이 소정 곡면으로 굽어진 형상의 컬(curl)이 형성되도록 하여 선단정렬을 위함이다. 상기 잼감지센서(47) 및 레지스트레이션센서(51)는 급지된 용지의 잼 여부를 감지한다.Therefore, the pickup clutch 35 is turned on by the signal transmitted from the developing unit of the printer, and accordingly, the pickup roller 31 is operated to feed the paper mounted on the paper feed unit 11. On the other hand, the registration clutch 55 is turned on after a predetermined time, for example, after 3.33 seconds after the pickup clutch 35 is turned on, and drives the front end alignment roller 53 to transfer the paper toward the transfer unit 80. The reason why the registration clutch 55 is driven with a time difference is to align the front end by forming curls having a shape in which the leading end of the sheet of paper is bent to a predetermined curved surface. The jam sensor 47 and the registration sensor 51 detect whether or not the paper is jammed.

상기한 바와 같이 급지장치를 동작하는 경우에는 인쇄용지의 컬량이 일정하도록 유지하기 위한 방법이 개시되어 있지 않았다.As described above, when the paper feeding apparatus is operated, a method for maintaining the curl amount of the printing paper to be kept constant is not disclosed.

이에 따라 용지선단이 급지부(11)의 정렬위치에 대해 앞선 경우는 상기 선단정렬롤러(53)에서 컬이 과도하게 발생하여 용지의 잼이나 접힘이 발생할 우려가 있다. 또한, 픽업롤러(31)에 대한 용지의 미끌림등에 의해 용지선단이 밀린 경우, 선단정렬롤러(53)에서의 컬이 적게 발생하거나 발생되지 않음으로 용지선단의 스큐에러가 발생할 수 있다.Accordingly, when the leading edge of the paper advances to the alignment position of the paper feeder 11, excessive curl occurs in the leading alignment roller 53, which may cause jamming or folding of the paper. In addition, when the leading edge of the sheet is pushed due to the sliding of the paper with respect to the pickup roller 31, the curling of the leading edge roller 53 may occur less or less, thereby causing a skew error at the leading edge of the paper.

따라서, 본 발명은 상기한 바와 같은 점을 감안하여 안출된 것으로서, 인쇄용지 컬량을 조절하여 인쇄용지의 선단 스큐 및 접힘을 방지할 수 있도록 된 인쇄기용 급지장치의 인쇄용지 컬량 조절방법을 제공하는데 그 목적이 있다.Accordingly, the present invention has been made in view of the above-described point, and provides a method for adjusting the amount of printing paper curl of the paper feeder for printing machine which can prevent the tip skew and folding of the printing paper by adjusting the amount of printing paper curl. There is a purpose.

이후, 상기 픽업클러치(35) 온 이후 소정시간 T2 이내에 상기 레지스트레이션센서(51)가 온 되는지 여부를 판단한다(S50). 온 된 경우는 정상적으로 다음 단계를 진행하고, 그렇지 않은 경우는 잼처리한다.Thereafter, it is determined whether the registration sensor 51 is turned on within a predetermined time T2 after the pickup clutch 35 is turned on (S50). If it is on, proceed to the next step normally, otherwise, jam.

이어서, 상기 레지스트레이션센서(51)의 온(ON) 이후 소정시간 T3 동안 픽업된 용지를 진행시킨후(S60) 상기 구동원(20)을 정지시킨다(S70). 상기 구동원(20)의 정지에 의해 용지를 전달하는 가이드롤러(45)가 정지되어 용지의 진행을 멈추게 된다. 한편, T3 시간동안 용지의 진행시, 용지의 선단이 상기 선단정렬롤러(53)에 막힌 상태로 소정 시간 경과되므로 용지 선단에 컬이 발생되며, 레지스트레이션센서(51)와 선단정렬롤러(53) 사이의 간격 및 용지 이송속도가 일정하므로 시간 제어를 통해 용지선단의 컬량이 일정하게 유지될 수 있다. 이어서, 감광매체(70)에 현상된 화상에 용지가 매칭되었는지 여부를 시간을 통해 판단한 후(S80), 화상과 용지가 매칭된 경우 용지를 전사유니트(80)에 급지한다. 용지의 급지는 상기 구동원(20)을 재 구동하고(S90), 상기 레지스트레이션클러치(55)를 온(ON) 시킴으로써(S100) 선단정렬롤러(53)를 구동하여 용지를 전사유니트(80)에 급지한다. 마지막으로 급지완료후 상기 레지스트레이션클러치(55)를 오프시키고(S130) 및 상기 구동원(20)을 정지시킨다. 여기서, 급지완료는 용지의 통과에 의한 레지스트레이션센서(51)의 오프 여부를 판별한 후(S110), 오프된 후 소정시간 T4 경과후의 시간으로 판별한다(S120).Subsequently, after driving the paper picked up for a predetermined time T3 after the registration sensor 51 is turned on (S60), the driving source 20 is stopped (S70). By the stop of the drive source 20, the guide roller 45 for transferring the paper is stopped to stop the progress of the paper. On the other hand, when the paper advances for a period of time T3, curl is generated at the leading edge of the paper because a predetermined time has elapsed while the leading edge of the paper is blocked by the leading alignment roller 53, and between the registration sensor 51 and the leading alignment roller 53. Since the interval of the paper and the paper feed speed is constant, the amount of curl at the leading edge can be kept constant through time control. Subsequently, after determining whether paper is matched with the image developed on the photosensitive medium 70 through time (S80), when the image and paper are matched, the paper is fed to the transfer unit 80. The paper feed is driven by the drive source 20 again (S90), and the registration clutch 55 is turned on (S100) to drive the front end alignment roller 53 to feed the paper into the transfer unit 80. do. Finally, after the paper feeding is completed, the registration clutch 55 is turned off (S130) and the driving source 20 is stopped. Here, the paper feeding completion is determined whether the registration sensor 51 is turned off by the passage of the paper (S110), and after the off time is determined as the time after a predetermined time T4 elapses (S120).

상기한 바와 같은 방법에 의해 용지선단의 컬량을 조절함으로써, 용지선단이 급지부의 정렬위치에 대해 앞선 경우 또는 픽업롤러에 대한 용지의 미끌림등에 의해 용지선단이 밀린 경우에도 선단정렬롤러의 전단에서 형성되는 용지선단의 컬량이 일정하게 유지할 수 있다. 이에 따라 용지의 컬량 과다에 따른 용지 잼 및 접힘과, 컬량 부족에 따른 용지선단의 스큐 에러 발생을 근본적으로 배제할 수 있다.By adjusting the curl amount of the leading edge by the method as described above, it is formed at the front end of the leading edge alignment roller even when the leading edge advances to the alignment position of the paper feeder or when the leading edge is pushed due to the sliding of the paper with respect to the pickup roller. The curl amount at the leading edge can be kept constant. Accordingly, it is possible to fundamentally exclude the occurrence of paper jams and folding due to excessive curl amount of the paper and the occurrence of skew error at the leading edge due to insufficient curling amount.
