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 배지롤러(14)의 주변부 즉, 상,하,측부에 틈새가 존재하기 때문에, 그 틈새를 통해 상기 본체(10) 내부에 존재하던 잉크용제 기체가 상기 배지구(15)로 빠져나갈 수 있게 된다. 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 있다. 즉, 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.However, in the above configuration, since a gap exists in the periphery of the discharge roller 14, that is, the top, the bottom, and the side, the ink solvent gas existing in the main body 10 through the gap is discharged from the discharge port 15 You can exit. This may be particularly problematic in the case of a printing apparatus using a liquid norpar as a carrier of a toner, that is, an ink solvent, in the printing unit 13, such as a color laser printer. In other words, if the old woman is not completely recovered and floats inside the main body 10 in a partially evaporated state, it is likely that it will leak out through the discharge port 15 in the above-mentioned gap.
