Description

인쇄기기의 급배지장치Paper feeder of printing machine

본 발명은 인쇄기기의 급배지장치에 관한 것으로, 특히 급지구나 배지구를 통해 유해물질이 배출되지 않도록 된 인쇄기기의 급배지장치에 관한 것이다.The present invention relates to a paper feeding and dispensing apparatus of a printing machine, and more particularly to a paper feeding and dispensing apparatus of the printer to prevent harmful substances are discharged through the paper feeder or discharge port.

예컨대 칼라 레이저 프린터와 같은 인쇄기기에는, 도 1에 도시된 바와 같이, 프린터 본체(10)에 착탈가능하게 결합되며 복수매의 용지(1)가 수납되는 카세트(11)와, 상기 카세트(11)로부터 용지를 인출하여 인쇄유니트(13)로 이송시키는 복수의 이송롤러(12)들을 포함한 급지유니트와, 상기 인쇄유니트(13)에서 인쇄가 완료된 용지를 본체(10) 외부로 배출하는 배지롤러(14)를 포함한 배지유니트가 구비되어 있다. 따라서, 인쇄작업을 수행할 때에는, 상기 카세트(11)로부터 상기 인쇄유니트(13)로 용지를 이송시키며, 그 인쇄유니트(13)에 의해 인쇄가 완료된 용지를 배지구(15)를 통해 다시 본체(10) 외부로 배출시키게 된다. 도면의 참조부호 16은 배출된 용지가 적재되는 배지트레이를 나타낸다.In a printing apparatus such as, for example, a color laser printer, as shown in FIG. 1, a cassette 11 detachably coupled to the printer main body 10 and a plurality of sheets of paper 1 are accommodated, and the cassette 11. A paper feed unit including a plurality of feed rollers 12 for extracting paper from the paper and transporting the paper to the printing unit 13, and a discharge roller 14 for discharging the paper on which the printing is completed in the printing unit 13 to the outside of the main body 10. A medium unit including) is provided. Therefore, when performing a print job, the paper is transferred from the cassette 11 to the print unit 13, and the paper on which printing is completed by the print unit 13 is again carried out through the discharge port 15. 10) It will be discharged to the outside. Reference numeral 16 in the drawing represents a discharge tray on which discharged paper is loaded.

그런데 상기 구성에 있어서는, 상기 배지구(15)를 통해 상기 본체(10) 내부에서 발생된 이물질이 외부로 빠져나갈 수 있는 문제점이 있다. 이는 칼라 레이저 프린터와 같이, 상기 인쇄유니트(13)에서 액상의 노파(norpar)를 토너(toner)의 캐리어 즉, 잉크 용제로 사용하는 인쇄기기의 경우에 특히 문제가 될 수 있는데, 만일 상기 노파가 완전히 회수되지 않고 일부 기화된 상태로 본체(10) 내부에서 부유하고 있게 되면, 그것이 상기한 틈새를 타고 배지구(15)를 통해 외부로 유출될 가능성이 있다. 이 노파는 외부로 유출될 경우 주변환경을 오염시킬 위험이 있는 물질이므로, 상기 노파와 같은 이물질의 유출 가능성을 최대한 억제할 필요가 있는 것이다.By the way, in the above configuration, there is a problem that foreign matter generated inside the main body 10 can escape to the outside through the discharge port 15. This can be particularly problematic in the case of a printing machine using a liquid norpar in the printing unit 13 as a carrier of a toner, that is, an ink solvent, such as a color laser printer. If it floats inside the main body 10 in a partially evaporated state without being fully recovered, there is a possibility that it flows out through the discharge port 15 in the above-mentioned gap. Since the old woman is a substance that is likely to pollute the surrounding environment when it is leaked to the outside, it is necessary to minimize the possibility of leakage of foreign substances such as the old woman.

한편, 도면에는 도시하지 않았으나, 본체(10) 일측벽에 급지구를 마련하여 그 급지구를 통해 용지를 본체(10) 내부로 공급하는 인쇄기기의 경우에는, 이 급지구 측에서도 상기한 배지구(15)측과 동일한 노파 유출 가능성이 문제가 될 수 있다.On the other hand, although not shown in the drawing, in the case of a printing apparatus that provides a paper feed port on one side of the main body 10 and feeds the paper into the main body 10 through the paper feed port, the above-described discharge port ( The same possibility of leaking an old woman like that of side 15 may be a problem.

본 발명은 상기의 점을 감안하여 창출된 것으로서, 급지구나 배지구를 통해 본체 내부에서 발생된 잉크 용제 기체등의 이물질이 배출되지 않도록 구조 개선된 인쇄기기의 급배지장치를 제공하는데 그 목적이 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object thereof is to provide a paper feeding and discharging device of a printing machine whose structure is improved so that foreign substances such as ink solvent gas generated inside the main body are not discharged through the paper feeding or discharge port. .

이하 첨부된 도면을 참조하면서, 본 발명에 따른 바람직한 실시예를 상세히 설명하기로 한다. 먼저 본 실시예는 급지유니트가 본체(100)에 결합된 카세트로부터 용지를 공급하는 구성으로 된 인쇄기기의 경우를 감안하여, 배지유니트 측에 초점을 맞춘 것이다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, the present embodiment focuses on the discharge unit side in consideration of the case of the printing apparatus in which the paper feed unit is configured to supply paper from the cassette coupled to the main body 100.

도 2 및 도 3은 본 발명에 따른 인쇄기기의 급배지장치를 나타낸다.2 and 3 show a paper feeding and discharging device of the printing machine according to the present invention.

먼저 도 2를 참조하면, 용지를 배출하기 위한 배지유니트로서, 본체(100)의 일측벽(110)에 형성된 배지구(150)의 인접 위치에 상부배지롤러(141)와 하부배지롤러(142)로 구성된 배지롤러(140)가 설치되어 있다. 이 상,하부배지롤러(141)(142)는 상호 밀착되어 회전하면서 인쇄유니트(130)에서 인쇄가 완료된 용지를 상기 배지구(150)를 통해 밀어내게 된다. 그리고 인쇄유니트(130)에서 발생되는 노파와 같은 이물질이 상기 배지구(150)로 빠져나가지 못하게 하기 위한 것으로, 상기 배지롤러(140) 측에서 상기 인쇄유니트(130) 측으로 에어를 분사하는 에어분사수단이 마련되어 있다.First, referring to FIG. 2, an upper discharge roller 141 and a lower discharge roller 142 are disposed at an adjacent position of the discharge port 150 formed on one side wall 110 of the main body 100 as a discharge unit for discharging paper. The discharge roller 140 consisting of is installed. The upper and lower media rollers 141 and 142 are in close contact with each other while being rotated to push the printed paper out of the printing unit 130 through the discharge port 150. And air injection means for injecting air from the printing unit 130 to the foreign matter, such as old hapa to the discharge port 150, the jet roller 140 side to the printing unit 130 side This is provided.

이 에어분사수단은, 도 2 및 도 3에 도시된 바와 같이, 에어 공급원인 송풍팬 유닛(170)과, 상기 상부배지롤러(141)의 상측반원부와 상기 하부배지롤러(142)의 하측반원부에 각각 씌워지는 노즐케이스(121)(122)를 포함하여 구성된다. 상기 노즐케이스(121)(122)에는 각각 상기 송풍팬 유닛(170)과 연결된 노즐부(121a)(122a)가 마련되어 있어서, 상기 송풍팬 유닛(170)에서 공급된 에어를 그 노즐부(121a)(122a)를 통해 분사할 수 있도록 되어 있다. 그리고 이 노즐부(121a)(122a)의 에어 분사방향은, 상기 배지롤러(121)(122)에서 상기 인쇄유니트(130) 측으로 향하도록 구성되어 있어서, 그 인쇄유니트(130)에서 발생된 이물질을 배지구(150) 측으로 나오지 못하게 하고 있다. 도 2의 참조부호 160은 배출된 용지가 적재되는 배지트레이를 나타낸다.As shown in Figs. 2 and 3, the air injection means is a blower fan unit 170 that is an air supply source, an upper semicircular portion of the upper medium roller 141, and a lower half circle of the lower medium roller 142. It is comprised including the nozzle cases 121 and 122 which respectively cover a part. The nozzle cases 121 and 122 are respectively provided with nozzle portions 121a and 122a connected to the blowing fan unit 170, and the air supplied from the blowing fan unit 170 receives the nozzle portion 121a. It is made to be able to inject through 122a. In addition, the air jet direction of the nozzles 121a and 122a is configured to be directed from the discharge rollers 121 and 122 toward the printing unit 130, so that foreign matters generated by the printing unit 130 are removed. It does not come out to the discharge outlet 150 side. Reference numeral 160 in FIG. 2 denotes an output tray on which discharged paper is loaded.

이와 같은 구성에 있어서 인쇄작업이 진행되면, 상기 인쇄유니트(130)에서 인쇄 완료된 용지가 상기 상,하부배지롤러(141)(142) 사이에 물려서 배지구(150)를 통해 외부로 배출된다. 이때 상기 노즐부(121a)(122a)로는, 상기 송풍팬 유닛(170)에서 공급되는 에어가 상기 인쇄유니트(130) 측을 향해서 분사되고 있다. 따라서 상기 본체(100) 내부에 존재할 수 있는 이물질은 상기 노즐부(121a)(122a)를 통해 분사되는 에어에 의해 차단되어 배지구(150) 측으로 유출될 수 없게 된다.In such a configuration, when a print job is performed, the printed paper in the printing unit 130 is seized between the upper and lower media rollers 141 and 142 to be discharged to the outside through the discharge port 150. At this time, the air supplied from the blowing fan unit 170 is injected toward the printing unit 130 to the nozzle parts 121a and 122a. Therefore, the foreign matter that may exist inside the main body 100 is blocked by the air injected through the nozzles 121a and 122a and thus cannot be discharged to the discharge port 150.

이와 같이 본 발명의 급배지장치에 의하면, 인쇄작업시에 상기 인쇄유니트(130) 측으로 에어를 분사함으로써, 노파와 같은 이물질이 본체 내부에서 빠져나오지 못하도록 갇워둘 수 있게 된다.As described above, according to the feeding and dispensing apparatus of the present invention, by spraying air toward the printing unit 130 during a printing operation, it is possible to trap foreign substances such as old women so as not to escape from inside the main body.

한편, 전술한 바와 같이 본 실시예에서는 용지가 본체(100)에 착탈되는 카세트(11; 도 1 참조)로부터 공급되는 인쇄기기의 경우를 감안하여 배지유니트에 에어분사수단을 설치하였으나, 만일 도 4에 도시된 바와 같이 급지유니트가 본체(100)에 형성된 급지구(190)를 통해 인쇄유니트로 용지를 급지하도록 구성된 인쇄기기의 경우 즉, 급지유니트 측에도 본체(100) 외부와 통하는 개구부가 있을 경우에는, 용지를 본체(100) 안으로 급지하는 급지롤러(180)에도 동일한 노즐케이스(121')(122')를 설치하여, 노즐부(121a')(122a')를 통해 인쇄유니트(130) 측으로 에어를 분사하게 구성할 수 있다.On the other hand, as described above, in the present embodiment, in consideration of the case of the printing apparatus supplied from the cassette 11 (see Fig. 1) in which the paper is detached from the main body 100, the air injection means is installed in the discharge unit.
