본 고안은 통상의 팩시밀리에 있어서 전송하려는 여러장의 원고를 일정한 간격을 유지하면서 자동으로 분리공급하는 원고 자동 급지장치의 개량에 관한 것이며, 특히 동력 접속과 차단의 기능을 가진 클러치의 구조개량에 주안점을 둔 것이다.The present invention relates to the improvement of the automatic document feeder which automatically separates and feeds a plurality of originals to be sent in a regular facsimile at regular intervals, and in particular, focuses on the structural improvement of a clutch having a function of power connection and disconnection. I put it.

종래 팩시밀리에 있어서의 원고 자동 급지장치는 제1도에 나타난 바와 같이, 급지로울러(1)측의 동력을 한쌍으로 이뤄지는 이송로울러(2)(3)에 전달하도록 갖춘 동력전달계통에 있어서 급지로울러(1)의 축단에 마그네틱 클러치(4)을 설치하고, 이 마그네틱 클러치를 제어하기 위한 별도의 제어회로(도시 생략)를 내장하여 급지로울러를 비롯하여 이송로울러의 회전과 비회전에 의하여 용지를 급지 시키거나 또는 급지를 중단시키도록 구성되어 있다.The automatic document feeder of the conventional facsimile machine has a paper feed roller in a power transmission system provided to transfer the power of the feed roller 1 side to a pair of feed rollers 2 and 3 as shown in FIG. The magnetic clutch 4 is installed at the shaft end of 1), and a separate control circuit (not shown) for controlling the magnetic clutch is built in to feed the paper by rotation and non-rotation of the feed roller as well as the feed roller. Or stop feeding.

그런데, 이와같은 종래의 마그네틱 클러치 방식에 의한 동력의 단속구조는 마그네틱 클러치의 원가부담이 큰데다가 이것의 작동에 필요한 독자적인 회로장치가 추가 장치되므로서 그러한 부담이 더욱 가중될뿐만 아니라 구조적으로도 복잡한 형상을 띄기 때문에 조립과정에서의 작업성에도 문제가 생길뿐 아니라 고장도 잦고 수리나 보수하기도 곤란한 점등의 결점이 있었다.However, the power interruption structure of the conventional magnetic clutch system is not only a burden of the magnetic clutch, but also an additional circuit device necessary for its operation, which adds to the burden and further structurally complicated shape. As a result, the workability during assembly was not only a problem, but also a defect of lighting that was frequently troubled and difficult to repair or repair.

본 고안은 상기와 갈은 문제점을 고려하여, 급지로울러와 이송로울러의 동력 접속에 필요한 단속부재를 일방향 클러치로 대체하는 동시에 이에 필요한 동력전달체계를 갖춘 새로운 구조의 자동 원고 급지장치를 제공하므로서 이 부분에 관련된 제작단가의 경감과 아울러 조립생산성 향상에 기여하며 아울러 구조 단순화에 따른 고장발생율의 대폭적인 감축과 함께 보수성 진보에도 크게 도움이 되도록한 것으로서, 이하 제2도 이하의 첨부도면과 관련지어 본 고안의 실시예를 구체적으로 설명한다.In view of the above and other problems, the present invention replaces the intermittent member required for the power connection of the feed rollers and the transfer rollers with a one-way clutch, and at the same time provides a new document feeder having a new structure with a power transmission system. In addition to the reduction of manufacturing costs related to the above, it contributes to the improvement of assembly productivity, and greatly helps the improvement of conservatism with the drastic reduction of the failure rate due to the simplification of the structure. An embodiment of will be described in detail.

모터의 구동축에 설치되는 구동기어(11)와 제1이송로울러(13) 축상의 종동기어(15) 사이에는 회전방향의 전환과 감속을 위한 두개의 아이들기어(16)(17)가 설치되어 있고, 또한 상기 종동기어(15)의 내측 접속기어(18)는 급지로울러(12) 축상의 종동기어(19)와 맞물려 있다. 이상 설명한 기어군은 구동(모터)측 동력전달계통이다. 이러한 동력전달체계에 의해서 선택적이긴 하지만 구동로울러(12)와 제1이송로울러(13)의 회전과 정지가 가능하게 되는 것이다.Between the drive gear 11 and the driven gear 15 on the first feed roller 13 shaft installed in the drive shaft of the motor, two idler gears 16 and 17 are provided for switching and reducing the rotational direction. In addition, the inner connecting gear 18 of the driven gear 15 is engaged with the driven gear 19 on the feed roller 12 axis. The gear group described above is the drive (motor) side power transmission system. Although selective by this power transmission system, the driving roller 12 and the first feed roller 13 can be rotated and stopped.

한편, 제2이송로울러(14)의 동력전달계통은 상기의 동력전달 체계와는 대향위치에 존재한다. 이것을 급지로울러(12) 축상의 구동기어(19'), 아이들러(20), 제1이송로울러(13) 축상의 종동기어(21) 및 그 벨트차(22), 그리고 제2이송로울러(14) 축상의 벨트차(23)로 이뤄지고 여기서 두 벨트차(22)(23)간에 두른 무한궤도형 타이밍 벨트(24)로 구성되어 있다.On the other hand, the power transmission system of the second feed roller 14 is in a position opposite to the power transmission system. The drive gear 19 'on the feed roller 12 shaft, the idler 20, the driven gear 21 on the shaft of the first feed roller 13, its belt car 22, and the second feed roller 14 It consists of an axial belt car 23 and consists of an endless track timing belt 24 between two belt cars 22 and 23.

본 고안의 주된 요체는 바로 이러한 동력전달체계를 갖춘 가운데 급지로울러(12)의 양측 종동기어(19)(19')와 제1이송로울러(13)의 종동기어(15)가 다같이 한방향으로 회전할때에만 동력이 걸리는 이른바 일방향 클러치(25)(25')(26)을 개재하여 각각의 축상에 결합되고 있으며 상기 일방향 클러치의 동력전달 방향은 일방향클러치(25,25')와 일방향 클러치(26)은 서로 반대 방향성을 갖는다.The main element of the present invention is that the driven gears (19) (19 ') of the feed roller (12) and the driven gear (15) of the first feed roller (13) rotate together in one direction with this power transmission system. It is coupled to each shaft via so-called one-way clutches 25, 25 'and 26, which are powered only when the power is applied, and the power transmission directions of the one-way clutches are one-way clutches 25 and 25' and one-way clutches 26. ) Have opposite directions from each other.

원고투입부에 전송을 목적으로 하는 원고를 투입하면 이 상태를 원고감지센서가 감지하여 모터측에 전기적신호를 보내고, 이 신호에 따라 모터가 가동한다. 이때 모터기어(11)는 반시계 방향으로 회전하며, 그 회전력은 아이들러기어(16)(17)를 거쳐 제1이송로울러(13)의 종동기어(15)와 다시 급지로울러(12)의 종동기어(19)로 전달되는데, 이때 제1이송로울러(13)는 그 종동기어(15)에 딸린 일방향 클러치(26)에 의해 동력이 접속되지않은 상태이므로 공회전하고 급지로울러(12)는 그 반대의 상태로 되어 구동하게 된다. 그러나, 상기 급지로울러(12)는 회전력은 반대쪽 종동기어(19')를 통해 아이들러(20)를 거쳐 제1이송로울러(13)의 또다른 종동기어(21)에 전달되므로서 그리고 또한 타이밍 벨트(24)에 의해서 제2이송로울러(14)까지 모두 회전되고, 따라서 원고의 이송이 이뤄진다.When a document for the purpose of transmission is inserted into the document input section, the document detection sensor detects this condition and sends an electric signal to the motor side, and the motor operates according to this signal. At this time, the motor gear 11 rotates in the counterclockwise direction, and the rotational force is driven by the driven gear 15 of the first feed roller 13 and the driven gear 12 again through the idler gears 16 and 17. In this case, the first feed roller 13 is idle because the power is not connected by the one-way clutch 26 attached to the driven gear 15, and the feed roller 12 is in the opposite state. Will be driven. However, the feed roller 12 has a rotational force transmitted through the opposite driven gear 19 'via the idler 20 to another driven gear 21 of the first feed roller 13 and also with a timing belt ( 24) are all rotated up to the 2nd feed roller 14, and conveyance of an original is made.

이때, 원고의 선단이 도시하지 아니한 스캐닝부위에 당도하면 이 상태가 스캐닝감지센서에 감지되고 이 신호는 즉시 모터측에 전달, 반시계 방향으로의 가동이 중지된다.At this time, when the leading edge of the document reaches the scanning part (not shown), this state is detected by the scanning sensor and the signal is immediately transmitted to the motor side, and the operation in the counterclockwise direction is stopped.

그후 복사지시 버튼이나 송신버튼을 누르면 이번에는 모터가 시계방향으로 회전하고 이에 따라 상기 각 구성요소들의 이제까지의 움직임과는 정반대의 현상이 일어난다. 즉, 공전되던 제1이송로울러(13)측의 종동기어(15)는 동력이 걸려서 회전하고 급지로울러(12)의 종동기어(19)(19')에는 일방향 클러치(25)(25')에 동력이 걸리지 않아 공회전된다. 그리하여 이번에는 제1 및 제2이송로울러(13)(14)에 의한 급지된 원고의 이송 및 송출이 이뤄지는 것이다.Then, when the copy instruction button or the transmit button is pressed, this time the motor rotates clockwise, and thus the opposite phenomenon of the movement of each of the above components occurs. That is, the driven gear 15 on the side of the first feed roller 13 that is idle rotates with power, and the one-way clutch 25, 25 'is attached to the driven gears 19, 19' of the paper feed roller 12. No idling, idling. Thus, this time, the conveyed and sent out documents fed by the first and second transfer rollers 13 and 14 are made.

이상 설명한 바와같이 본 고안의 자동 원고 이송장치에 의하면 원고의 급지와 이송에 있어서 급지로울러와 이송로울러들에 동력을 접속하거나 차단해 주는 부재가 일방향 클러치로 이뤄지고 또한 이 접속기구의 단속에 전기적 회로장치가 전혀 불필요 하므로 자동 원고 급지장치의 구조가 대폭 단순화되므로서 원가 절감효과와 조립용이성, 보수성 향상효과를 가져온다.As described above, according to the automatic document feeder of the present invention, a member that connects or cuts power to the feed rollers and feed rollers in the feeding and conveying of the originals is composed of a one-way clutch and an electrical circuit device for interrupting the connecting mechanism. Since the structure of the automatic document feeder is greatly simplified, the cost saving effect, the ease of assembly, and the water retention are improved.
