Figure 4 is an enlarged view of the hinge portion rotatably coupled to the scanner unit in the present invention.
이에 도시한 바와 같이, 본 발명 실시예는 프린터 유니트(10)가 구비되는 기기 본체의 상면에 스캐너 유니트(20)가 커버의 기능을 수행하도록 개폐가능하게 설치되어 있다. 이때, 적용되는 스캐너 유니트(20)는 CIS(Contact Image Sensor)타입의 스캐너보다는 CCD(Charge Coupler Device) 타입의 스캐너를 적용하는 것이 바람직하다.As shown in the drawing, the embodiment of the present invention is provided to be openable and openable so that the scanner unit 20 performs a function of a cover on the upper surface of the main body of the apparatus in which the printer unit 10 is provided. At this time, it is preferable that the scanner unit 20 to be applied applies a scanner of a charge coupler device (CCD) type rather than a scanner of a CIS (Contact Image Sensor) type.
이와 같이 스캐너 유니트(20)가 기기 본체(1)에서 프린터 유니트(10)의 커버 기능을 수행하기 위해서 프린터 유니트(10)의 상면 가장자리에는 스캐너유니트 안착부(16)가 형성되어 있고, 스캐너 유니트 안착부(16)의 양측에는 힌지봉(17)이 구비되어 있다.In this way, the scanner unit seating portion 16 is formed at the top edge of the printer unit 10 so that the scanner unit 20 performs the cover function of the printer unit 10 in the main body 1 of the machine. Hinge rods 17 are provided on both sides of the portion 16.
또한, 스캐너 유니트(20)의 하면에는 양측으로 스캐너 유니트 안착부의 힌지봉(17)에 회전가능하게 결합되는 후크(22)가 형성되어 있어 스캐너 유니트(20)의 후크(22)가 스캐너 유니트 안착부의 힌지봉(17)에 삽입되어 있다.In addition, the lower surface of the scanner unit 20 is provided with a hook 22 rotatably coupled to the hinge rod 17 of the scanner unit seating portion on both sides, so that the hook 22 of the scanner unit 20 is attached to the scanner unit seating portion. It is inserted into the hinge rod 17.
프린터 유니트(10)의 구성인 급지대(11)와, 픽업롤러(12), 피드롤러(13), 잉크카트리지(14a)를 구비한 캐리어(14) 및 배지롤러(15)는 종래 구성과 동일하며, 스캐너 유니트(20)는 통상적인 CCD타입의 스캐너이다.The feeder 11, the pickup roller 12, the feed roller 13, the ink cartridge 14a, and the carrier 14 and the discharge roller 15, which are the configurations of the printer unit 10, are the same as in the conventional configuration. The scanner unit 20 is a conventional CCD type scanner.
이와 같이 구성되는 본 발명에 의한 복합기의 작용을 설명한다.The operation of the multifunction device according to the present invention configured as described above will be described.
도 1과 같이 프린터를 사용하는 경우에는 급지대(11)에 적재된 용지가 픽업 롤러(12)에 의해 프린팅 영역으로 픽업 되면 잉크 카트리지(14a)가 수납되어 있는 카트리지(14)가 횡방향으로 이동되면서 용지상에 프린팅을 실시하게 되며, 프린팅이 완료된 용지는 배지롤러(15)에 의해 복합기의 외부로 배출된다.In the case of using the printer as shown in Fig. 1, when the paper loaded in the tray 11 is picked up by the pickup roller 12 to the printing area, the cartridge 14, in which the ink cartridge 14a is housed, is moved laterally. The printing is carried out on the paper while the paper on which the printing is completed is discharged to the outside of the multifunction apparatus by the discharge roller 15.
한편, 스캐너를 사용하는 경우에는 도 2에서와 같이, 스캐너 유니트의 커버(21)를 개방시킨 상태에서 스캐닝 원고를 위치시킨 후, 커버(21)를 닫으면 스캐너 유니트(20)의 내부에 구비된 CCD센서(23)가 전후방으로 이동되면서 원고의 데이터를 스캐닝하게 된다.On the other hand, in the case of using a scanner, as shown in Fig. 2, after positioning the scanning document with the cover 21 of the scanner unit open, and closing the cover 21, the CCD provided inside the scanner unit 20 The sensor 23 is moved back and forth to scan the data of the document.
이와 같이 복합기의 프린터와 스캐너를 사용하다가 프린터 유니트의 내부 소모품을 교체하고자 하면, 스캐너 유니트(20)가 프린터 유니트(10)의 커버 역할을 수행하기 때문에 도 3에 도시한 바와 같이, 스캐너 유니트(20)를 프린터 유니트의 상측에서 힌지봉(17)을 중심으로 회전시켜 개방하면, 프린터 유니트의 내부가 외부로 노출되므로 작업자가 용이하게 프린터의 소모품 및 부품을 교체할 수 있게 된다.As described above, when the consumables of the multifunction printer and the scanner are to be used and the consumables of the printer unit are to be replaced, the scanner unit 20 serves as a cover of the printer unit 10, as shown in FIG. 3. ) By rotating the hinge rod 17 around the printer unit at the upper side of the printer unit, the inside of the printer unit is exposed to the outside, so that the operator can easily replace the consumables and parts of the printer.
이러한 스캐너 유니트는 본체의 힌지봉(17)에 후크(22)로 착탈가능하게 결합되어 있기 때문에 필요시에는 기기 본체(1)에서 분리하여 스캐너 유니트(20)만을 별도로 사용할 수 있게 된다.Since the scanner unit is detachably coupled to the hinge rod 17 of the main body by the hook 22, the scanner unit 20 can be separated from the main body 1 of the apparatus so that only the scanner unit 20 can be used separately.
이상에서 설명한 바와 같이, 본 발명에 의한 복합기는 스캐너 유니트를 프린터 유니트의 상측에 회전가능하게 설치하여 프린터의 내부가 외부에 노출가능하도록 커버로 채용함으로써 기능적으로 프린터 유니트의 소모품 및 부품의 교체가 간편해지는 효과가 있다.As described above, the multifunction device according to the present invention is installed by rotating the scanner unit on the upper side of the printer unit and employing the cover to expose the inside of the printer to the outside, thereby making it easy to replace consumables and parts of the printer unit functionally. There is a repelling effect.
