본 고안은 팩시밀리의 원고급장치, 더욱 상세히는 원고급지의 기능을 효과적으로 수행하면서도 그 구성 부품수를 최소화하여 조립성과 생산성을 대폭 향상시키게된 팩시밀리의 원고급지장치에 관한 것이다.The present invention relates to a facsimile document feeder, and more particularly to a facsimile document feeder, which effectively improves assembly and productivity by minimizing the number of components while effectively performing the function of the document feeder.
종래 팩시밀리에서의 원고급지장치(1)는 제1도에서와 같이 본체(도시하지 않음)에 조립되며 그 상면에 원고 이송로울러(21)가 설치된 안내하판(2)과, 안내하판(2)과의 사이에 원고이송통로(3)를 형성하는 안내상판(4)의 사이에 구비되며; 미끄럼마찰수단(5)과 탄성압박수단(6)으로 구성된다.The document feeder 1 of the conventional facsimile machine is assembled to a main body (not shown) as shown in FIG. 1, and a guide lower plate 2 having a document feed roller 21 mounted on an upper surface thereof, a guide lower plate 2, It is provided between the guide upper plate 4 which forms the document feed passage (3) between the; It is composed of the sliding friction means 5 and the elastic pressing means (6).
미끄럼 마찰수단(5)은, 안내상판(4)의 소정부위에 구비되어 원고이송통로(3)로 연장설치되는 미끄럼판(51)과, 미끄럼판(51)의 하단에 구비되어 원고이송로울러(21)와 접촉하는 고무재의 밀착부재(52)와, 미끄럼판(51)의 상면에 형성되어 안내상판(4)의 상면으로 돌출되는 걸림부(53)로 구성된다.The sliding friction means (5) is provided at a predetermined portion of the guide upper plate (4) and is provided at the lower end of the sliding plate (51) and a sliding plate (51) extending to the document feed passage (3). 21 is formed of a close contact member 52 of rubber material in contact with 21 and a locking portion 53 formed on the upper surface of the sliding plate 51 and protruding to the upper surface of the guide upper plate 4.
탄성압박수단(6)은, 안내상판(4)의 상면소정부위에 돌출형성된 고정부(61)와, 고정부(61)에 체결부재(62)로 고정되는 판상의 탄성부재(63)와, 탄성부재(63)의 끝단에 구비되고 상기 걸림부(53)에 안착되어 하향된 탄성을 부여하는 압박부(64)로 구성된다.The elastic pressing means 6 includes a fixing portion 61 protruding on the upper surface small portion of the guide upper plate 4, a plate-shaped elastic member 63 fixed to the fixing portion 61 by a fastening member 62, The pressing member 64 is provided at the end of the elastic member 63 and seated on the locking portion 53 to impart downward elasticity.
도면중 미설명부호(7)은 급지용 원고이다.In the drawing, reference numeral 7 denotes a document for feeding.
이와같은 구성의 원고급지장치(1)는 원고이송통로(3)의 안내하판(2)의 다수의 원고(7)를 적층셋트시킨 상태에서 송신을 개시하면, 원고(7)는 원고이송로울러(21)와 밀착부재(52) 사이의 마찰압박력에 의해 한장씩 원고이송통로(3)를 따라 급지되며, 이때 밀착부재(52)가 위치고정된 원고이송통로(21)에 대해 작용하는 압박력은, 밀착부재(52)를 고정하는 미끄럼판(51) 상면의 걸림부(53)에 안착된 압박부(64)에서 부여하게 된다.When the document feeder 1 having such a configuration starts transmission in a state in which a plurality of documents 7 of the guide lower plate 2 of the document feed passage 3 are stacked, the document 7 is fed with a document feed roller ( 21) is fed along the document feed passage 3 by one by the frictional pressing force between the contact member 52, wherein the pressing force acting on the document feed passage 21 in which the contact member 52 is fixed is in close contact with each other. The pressing portion 64 mounted on the locking portion 53 on the upper surface of the sliding plate 51 to fix the member 52 is applied.
그런데, 이러한 구성에서의 문제점은 우선, 원고급지장치(1)를 구성하는 미끄럼 마찰수단(5)과 탄성압박수단(6)이 많은 부품으로 복잡하게 있으므로, 부품수 증가에 의한 제작성, 조립성이 극도로 저하되고, 소요자재 증가에 의한 원가상승과 높은 고장율을 나타내는 주요인을 제공하게 된다는 점이다.However, the problem in this configuration is that the sliding friction means 5 and the elastic pressing means 6 constituting the document feeder 1 are complicated by many parts. This is extremely low, and the main reason for the cost increase and the high failure rate due to the increase of necessary materials is provided.
또한, 원고(7)의 급지시에는, 탄성압박수단(6)을 구성하는 탄성부재(63) 끝단부위의 압박부(64)가 미끄럼 마찰수단(5)의 미끄럼판(51)을 1차로 가압하고, 미끄럼판(51)은 그 하단의 밀착부재(52)를 2차로 가압하는 구조적 문제점을 유발한다.In addition, at the time of feeding the document 7, the pressing portion 64 at the end of the elastic member 63 constituting the elastic pressing means 6 presses the sliding plate 51 of the sliding friction means 5 first. And, the sliding plate 51 causes a structural problem of pressing the contact member 52 of the lower end of the secondary.
이점은 특히 미끄럼판(51)의 설치상태에 따라 밀착부재(52)와 원고이송통로(21)간의 마찰압박력 변동을 초래하여, 원고(7)가 복수매 또는 접혀진 상태로 공급되거나 공급방향 변동의 원인을 제공함으로써 원고급지장치(1)로서의 기능을 상실하는 치명적 문제점을 지적된다.This may cause a frictional force fluctuation between the contact member 52 and the document feed passage 21, in particular, depending on the installation state of the sliding plate 51, so that a plurality of originals 7 are supplied or folded, By providing the cause, a fatal problem of losing the function as the document feeder 1 is pointed out.
본 고안은 상기한 문제점들을 감안하여 구성부품수를 최소화하고, 원고의 불량급지를 적극적으로 방지할 수 있는 팩시밀리의 원고급지장치를 제공함에 그 목적이 있는바, 이하에서 상기목적으로 달성하는 본 고안의 바람직한 실시예를 첨부도면에 의해 상세히 설명한다.The present invention aims to provide a document feeder of a facsimile capable of minimizing the number of components in consideration of the above-described problems and actively preventing defective feeding of a document. Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 고안 원고급지장치(1A)의 구성상 지배적 특징부는 종래 미끄럼마찰수단(5)과 탄성압박수단(6)이 수행하는 두기능을 독립된 하나의 탄성마찰 수단(8)으로 수행하게된 부분이다.The dominant feature in the construction of the document feeder 1A of the present invention is a part that performs the two functions performed by the conventional sliding friction means 5 and the elastic pressing means 6 as one independent elastic friction means 8.
탄성마찰수단(8)은 제2도에서와 같이, 원고이송로울러(21)가 설치된 안내하판(2)의 상부에 원고이송로울러(3)가 형성되도록 설치한 안내상판(4)에 설치됨은 종래와 동일하며; 안내상판(4)의 하면 요소에 구비된 고정돌기부(81)와, 고정돌기부(81)에 일측이 고정되며 타측이 원고이송로울러(21)와 접촉하는 고무재의 밀착부재(82)와, 안내상판(4)의 상면요소에 돌출형성된 고정부(83)와, 고정부(83)에 하향된 탄성을 갖도록 고정된 탄성부재(84)와, 탄성부재(84)의 하단에 절곡형성되어 밀착부재(82)에 하향된 탄성을 부여하는 압박부(85)로 구성된다.As shown in FIG. 2, the elastic friction means 8 is installed on the guide upper plate 4 provided so that the document feed roller 3 is formed on the upper part of the guide lower plate 2 on which the document feed roller 21 is installed. Same as; A fixing protrusion 81 provided on the lower surface element of the guide upper plate 4, a rubber-adhesive member 82 having one side fixed to the fixing protrusion 81 and the other side contacting the document feed roller 21, and a guide upper plate. The fixing portion 83 protruding from the upper surface element of (4), the elastic member 84 is fixed to have a downward elasticity to the fixing portion 83, and bent to the lower end of the elastic member 84 to form an adhesive member ( And a pressing part 85 for imparting downward elasticity to 82.
설명의 편의를 위해 종래와 동일한 부분, 부재에 대해서는 동일부재 번호를 사용하였다.For convenience of description, the same member numbers are used for the same parts and members as in the prior art.
이와같은 구성의 본 고안 급지장치(1A)는 원고(7)의 송신시에 원고이송로울러(21)가 구동하여 밀착부재(82)와의 사이로 원고(7)가 한장씩 이송되어 원고이송통로(3)를 통해 종래와 동일하다.The paper feeder 1A having the above-described structure is operated by the document feed roller 21 when the document 7 is transmitted, so that the document 7 is conveyed one by one between the contact member 82 and the document feed path 3. Through the same as in the prior art.
그러나 본 고안에서는 원고이송로울러(21)와의 사이에서 상대적인 마찰력차에 의해서 원고(7)를 한 장씩 공급하는 밀착부재(82)를 탄성부재(84)이 압박부(85)가 직접압박하도록 설치하여, 원고(7)의 분리를 위한 즉, 한 장씩 공급하기 위한 가압력은 밀착부재(82)에 전체적으로 균일하게 부여된다.However, in the present invention, the elastic member 84 is provided so that the pressing unit 85 directly presses the contact member 82 for supplying the document 7 one by one by the relative frictional force between the document feed roller 21. , The pressing force for separating the originals 7, that is, supplying one by one, is uniformly applied to the contact member 82 as a whole.
따라서, 말착부재(82)와 원고이송로울러(21)사이의 원고(7)은 양호한 상태로 한 장씩만 공급되므로 마찰압박력의 변도에 의한 불량공급의 우려는 적극적으로 배제된다.Therefore, since the originals 7 between the attachment member 82 and the document feed rollers 21 are supplied in good condition one by one, the possibility of poor supply due to the variation of the frictional pressure force is actively excluded.
이러한 작용상의 차이는 압박력으로 부여되는 탄성부재(84)의 탄성이 종래 미끄럼판(51)등의 중계없이 직접 밀착부재(82)에 가해지는 구조적 특성에 기인한다.This difference in action is due to the structural characteristics in which the elasticity of the elastic member 84 applied by the pressing force is applied directly to the close contact member 82 without relaying the conventional sliding plate 51 or the like.
또한 본 고안은, 탄성마찰수단(8)을 구성하는 부품수 및 형상이 최소화, 단수화 되어 제작이 용이하고 조립성이 향상되며, 이에따라 소요자재, 생산단가, 공수 및 고장발생율은 현저히 낮아진다.In addition, the present invention, the number and shape of the components constituting the elastic friction means (8) is minimized, reduced in number, easy to manufacture and improves the assembly, accordingly the required materials, production cost, man-hours and failure rate is significantly lowered.
이와같이 본고안 급지장치(1A)는 원고(7)의 불량급지를 근본적으로 해소할 수 있으면서도 그 구성이 단순하여 생산성 및 사용자의 작동신뢰성과 제품선호도를 대폭향상시킬 수 있는 등의 여러가지 잇점이 있다.As described above, the paper feeder 1A can solve the poor feeding of the original document 7 in its original form, but has a simple configuration, which can greatly improve productivity, user's operational reliability and product preference.
