제2도는 본 발명의 일예를 도시한 측면도.2 is a side view showing an example of the present invention.

제3도는 본 발명의 구동계의 사시도.3 is a perspective view of a drive system of the present invention.

제4도는 본 발명의 구동 제어회로도.4 is a drive control circuit diagram of the present invention.

본 발명은 급지(給紙)장치에 관한 것으로, 특히 급지 로울어와 분리로울러등에 의해, 복사용지, 복사원고 인쇄용지등의 종이를 1매씩 송출하기 위한 급지 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper feeder, and more particularly, to a paper feeder for feeding one sheet of paper such as copy paper, copy document printing paper, etc. by a feed roller and a separation roller.

종래로부터 급지로울러와 분리로울러를 사용한 급지로울러가 사용되어 왔으며, 이러한 급지장치는, 제1도에 계략적으로 도시한 바와같이, 급지로울러(a)와 분리로울러(b)를 접촉시켜 설치하고, 급지로울러(a)를 화살표 A방향으로, 또 분리로울러(b)를 슬립 클러치(c)를 통하여 화살표 B방향으로 구동케하고 있다. 그리하여, 상기 급지로울러(a)와 분리로울러(b)의 마찰력은, 슬립클러치(c)의 클러치판의 마찰력보다 크게되어 있고, 또 분리로울러(b)와 종이(d)와의 마찰력은 급지로울러(a)와 종이(d)와의 마찰력 및 슬립클러치(c)의 클러치 판의 마찰력보다 작게 설정되어 있다. 따라서, 급지로울러(a)가 정지하고 있는 상태에서는 분리로울러(b)도 정지하고, 슬립클러치(c)가 미끄러지고 있다. 그리하여 급지로울러(a)를 구동하면, 급지로울러(a)와 분리로울러(b)의 마찰력은, 슬립클러치(c)의 클러치판의 마찰력보다 크므로, 급지로울러(a)와 분리로울러(b)가 똑바로 회전하고, 양로울러(a, b)간에 종이(d)가 삽입되어, 분리로울러(b)는 종이(d)에 접속하도록되고, 분리로울러(b)와 종이(d)와의 마찰력은 슬립 클러치(c)의 클러치 판의 마찰력보다 작으므로 해서, 슬립클러치(c)가 미끄러지지 않게되므로, 분리로울러(b)가 화살표방(c)향으로 회전하여 분리 작용을 하고, 급지로울러(a)에 의해 최하위의 종이 1매만이 화살표 D방향으로 송출된다.Conventionally, a paper feed roller using a paper feed roller and a separation roller has been used. Such a paper feed device is installed by contacting the paper feed roller (a) and the separation roller (b), as shown schematically in FIG. The paper feed roller a is driven in the direction of arrow A, and the separation roller b is driven in the direction of arrow B through the slip clutch c. Thus, the frictional force of the feed roller a and the separation roller b is larger than the friction force of the clutch plate of the slip clutch c, and the frictional force of the separation roller b and the paper d is the feed roller ( It is set smaller than the frictional force between a) and the paper d and the frictional force of the clutch plate of the slip clutch c. Therefore, in the state where the paper feed roller a is stopped, the separation roller b is also stopped, and the slip clutch c slips. Thus, when the feed roller (a) is driven, the friction force of the feed roller (a) and the separation roller (b) is greater than the friction force of the clutch plate of the slip clutch (c), and therefore the feed roller (a) and the separation roller (b). Rotates straight, the paper d is inserted between the rollers a and b so that the separating roller b is connected to the paper d, and the friction force between the separating roller b and the paper d slips. Since the slip clutch c is not slipped because it is smaller than the frictional force of the clutch plate of the clutch c, the separation roller b rotates in the direction of the arrow direction c to act as a separation, and the feed roller a As a result, only the lowest sheet of paper is sent out in the direction of the arrow D. FIG.

그런데 이러한 종래의 급지장치는 2매이상의 종이가 동시서 송출되는 소위중송(重送)이 일어나기 쉽고, 이 중송은 급지가 고속으로 됨에 따라 증대하고, 급지장치의 고속화에 장해를 일으킨다.By the way, such a conventional paper feeder is easy to carry out what is called a heavy feeding in which two or more sheets of paper are simultaneously sent out, and this heavy feeding increases as the paper feed speed becomes high, and causes a problem in speeding up the paper feeder.

본 발명은 상기 문제점을 해결하기 위한것으로, 급지장치의 고속화를 손상시키지 않고, 중송이 방지되는 급지장치를 제공하는 것을 본 발명의 목적으로 한다.SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a paper feeding device in which feeding is prevented without damaging the speed of the paper feeding device.

하기에서 본 발명을 제2도 내지 제4도에 따라서 설명한다.The present invention will be described below with reference to FIGS. 2 to 4.

제2, 3도에서 본 발명을 복사기의 원고 자동 이송장치에 적용한 예를 도시하였고, 제4도에서 그 제어회로를 도시하였다.2 and 3 show an example in which the present invention is applied to an automatic document feeder of a copying machine, and FIG. 4 shows a control circuit thereof.

원고(1)는 트래이(2)내에 쌓아놓고, 최하위의 원고(1)는 급지로울러(3), 분리로울러(4)로부터 송출되고, 핀치로울러(5)를 통해 원고 반송용 벨트(6)에 의해 원고재치대(7)상에 셋트되어 복사시킨다. 복사를 완료한 원고(1)은 반송용벨트(6)에 의해 배출시킨다.The originals 1 are stacked in the tray 2, and the lowermost originals 1 are fed from the feed rollers 3 and the separation rollers 4, and are fed to the original conveyance belt 6 through the pinch rollers 5. Are set on the document table 7 and copied. The finished document 1 is discharged by the conveyance belt 6.

상기 급지로울러(3), 반송용 벨트(6) 및 핀치로울러(5)의 구동계통은 제3도와 같이 구성되어 있다. 즉, 모터(M)의 회전력은, 고속용 클러치(8) 및 에피 사이클 기어(9)로 구성되고, 상기 고속용클러치(8) 가 차단되면 저속회전, 상기 고속용 클러치(8)가 접속되면 고속회전을 전동하는 2단변속 기능을 구비한 전동기구를 거쳐 원동축(10)에 전달되고, 상기 원동축(10)에 설계된 푸리에 감겨진 구동용벨트(11) 및 구동용체인(12)에 의해, 급지로울러(3), 분리로울러(4) 및 반송용 벨트(6), 핀치로울러(5)가 구동되도록 되어있다. 또, (13)은 급지용 클러치, (14)는 슬립 클러치이다.The drive system of the paper feed roller 3, the conveyance belt 6 and the pinch roller 5 is configured as shown in FIG. That is, the rotational force of the motor M is composed of the high speed clutch 8 and the epicycle gear 9, and when the high speed clutch 8 is interrupted, the low speed rotation and the high speed clutch 8 are connected. It is transmitted to the drive shaft (10) via a transmission mechanism having a two-speed transmission function for transmitting high-speed rotation, and to the drive belt (11) and drive chain (12) wound around the Fourier designed on the drive shaft (10) Thereby, the paper feed roller 3, the separation roller 4, the conveyance belt 6, and the pinch roller 5 are driven. 13 is a paper feed clutch, and 14 is a slip clutch.

상술과 같이 구성된 원고 자동 이송장치의 작동을 제4도의 제어회로에 의해 설명한다.The operation of the automatic document feeder constructed as described above will be explained by the control circuit of FIG.

급지 트레이(2)상에 원고(1)을 세트하면, 마이크로스윗치(MS1)에 의해 릴레이(RL1)가 작동하고, 접점(S1)이 닫히고, 급지 개시 신호를 보내므로, 릴레이(RL6)가 자기 보지되고, 접점(S6-2)의 닫힘에 의해 모터(M)가 회전한다. 동시에 접점(S6-3)이 닫히므로 릴레이(RL4)의 접점(S4-1)의 노밀측에 의해 급지용클러치(13)의 코일(L1)이 여자(勵磁)되고, 급지용클러치(13)가 접속한다. 여기에서, 릴레이(RL3)는 작동상태에 있고, 접점(S3-2)는 열려있으므로, 코일(L2)은 소자(消磁)되어 있고, 고속용 클러치(8)는 차단되어 있다. 따라서 에피사이클 기어(9)의 축 전달에 의해 저속 〔실시예에서는 속도 비 1:1/41(3RPM)〕으로 급지로울러(3)가 회동하고, 트레이(2)상에 최하위의 원고(1)를 저속(실시예에서는 8㎜/sec)으로 송출한다.When the document 1 is placed on the paper feed tray 2, the relay RL 1 is activated by the micro switch MS 1 , the contact S 1 is closed, and a paper feed start signal is sent. 6 ) is self-holding, and the motor M rotates by closing the contact S 6-2 . At the same time, since the contact S 6-3 is closed, the coil L 1 of the paper feeding clutch 13 is excited by the dense side of the contact S 4-1 of the relay RL 4 . The paper clutch 13 is connected. Here, the relay RL 3 is in the operating state, and the contact S 3-2 is open, so that the coil L 2 is demagnetized, and the high speed clutch 8 is cut off. Therefore, the feed roller 3 rotates at a low speed (speed ratio 1: 1/41 (3 RPM in the embodiment) by the shaft transmission of the epicycle gear 9, and the lowest original 1 on the tray 2 is rotated. Is sent at a low speed (8 mm / sec in this embodiment).

또 상기 릴레이(RL6)의 자기 보지에 의해 접점(S6-1)이 닫히므로 타이머(T1)가 스타트하고, 1초후 타이머(T1)의 타임업에 의해 접점(S4-1)이 열리므로 릴레이(RL3)가 작동되지 않게되고, 접점(S3-2)의 접속에 의해 코일(L2)이 여자되고, 고속클러치(8)가 접속한다. 따라서, 에피 사이클 기어(9)의 외각 전달에 의해 고속(실시예에서는 340㎜/sec)으로 송출시킨다. 송출된 원고(1)는, 우선 마이크로 스윗치(MS2), 다음에 마이크로 스윗치(MS3)를 작동하고, 릴레이(RL4)가 자기 보지되어, 접점(S4)의 노멀측이 열려짐으로 코일(L1)이 소자(消磁)되고, 급지로울러(3)의 구동은 정지된다.In addition, since the contact S 6-1 is closed by the magnetic holding of the relay RL 6 , the timer T 1 starts, and after one second , the contact S 4-1 is stopped by the time-up of the timer T 1 . Since it opens, the relay RL 3 is not operated, the coil L 2 is excited by the connection of the contact S 3-2 , and the high speed clutch 8 is connected. Therefore, it transmits at high speed (340 mm / sec in an Example) by external transmission of the epicycle gear 9. The sent document 1 first operates the micro switch MS 2 and then the micro switch MS 3 , the relay RL 4 is self-holding, and the normal side of the contact S 4 is opened. The coil L 1 is demagnetized, and the driving of the paper feed roller 3 is stopped.

단 코일(L2)은 마이크로 스윗치(MS2)에 의해 여자를 지속한다. 따라서 그후의 원고(1)은 고속용 클러치(8)를 통하여 구동되고 있는 핀치 로울러(5) 및 반송용 벨트(6)에 의해 이송된다.However, the coil L 2 sustains the excitation by the micro switch MS 2 . The subsequent document 1 is thus conveyed by the pinch roller 5 and the conveyance belt 6 being driven through the high speed clutch 8.

원고(1)의 후단이 마이크로 스윗치(MS2)를 통과하면, 마이크로 스윗치(MS2)가 차단되고, 코일(L2)이 소자(消磁)되고, 고속용 클러치(8)가 차단되어 반송용 벨트(5)은 에피 사이클 기어(9)의 축 전달로 저속 구동된다. 또 계속하여 원고(1)의 후단통과에 의해, (MS3)도 차단되고, (S4-2)가 닫혀져 있으므로, 릴레이(RL5)가 작동하고, 이에 의해 접점(S5-1)이 접속하여 타이머(T2)(설정시간 2초)가 스타트된다. 이 타이머(T2)의 작동중원고(1)는 반송용 벨트(6)에 의해 저속으로 원고재치대(7)상에 정합된다. 또 동시에 접점(S5-2)의 접속에 의해 코일(L1)이 여자하고, 급지용 클러치(13)의 접속에 의해 급지 로울러(3)가 저속으로 회전하고, 다음의 원고를 저속으로 송출한다.When the trailing edge of the document 1 passes through the micro-switch (MS 2), the micro switch (MS 2) is cut off and the coil (L 2) is blocked, the device (消磁) and the high speed clutch (8) for the conveying The belt 5 is driven at low speed by the axial transmission of the epicycle gear 9. In addition, (MS 3 ) is also blocked by the trailing end of the document 1, and since (S 4-2 ) is closed, the relay RL 5 is activated, whereby the contact S 5-1 is closed. The timer T 2 (set time 2 seconds) is started by connecting. The document 1 during operation of the timer T 2 is matched on the document table 7 at a low speed by the conveyance belt 6. At the same time, the coil L 1 is excited by the connection of the contact S 5-2 , and the feeding roller 3 rotates at low speed by the connection of the feeding clutch 13, and the next original is sent at low speed. do.

그리하여 타이머(T2)의 타임업에 의한 릴레이(RL6)의 자기 보지가 해제되고, 모터(M)가 정지된다. 이것에 의해 원고재치대(7)상의 원고(1)는 복사위치에서 정지하고, 또 다음의 원고(1)은 급지로울러(3)에서 약간 송출된 그대로 정지된다.Thus, the self holding of the relay RL 6 due to the time-up of the timer T 2 is released, and the motor M is stopped. As a result, the original 1 on the document holder 7 is stopped at the copying position, and the next original 1 is stopped as it is slightly sent out from the paper feed roller 3.

또, 타이머(T2)의 타임업에 의해 복사중의 신호를 보내고, 복사중에는 릴레이(RL2)가 작동하여 릴레이(RL3)는 작동하지 않는 상태를 계속한다.Moreover, the copying signal is sent by the time-up of the timer T 2 , and during the copying, the relay RL 2 is operated and the relay RL 3 continues to be in an inactive state.

다음에 또 급지 개시신호를 보내면, 릴레이(RL6)가 자기 보지하고, 모터(M)가 회동한다. 이때에, 릴레이(RL3)가 작동하지 않은 상태에 있기 때문에, 접점(S3-2)의 접속과 접점(S4)의 노멀측에 의해 코일(L1)이 여자되어 있고, 고속용 클러치(8)가 접속되어 있는 상태에서 코일(L1)도 여자되고, 급지용 클러치(13)가 접속한다. 이에 의해, 급지 로울러(3)의 저속 이송으로 약간 송출된 다음의 원고(1)는 고속으로 송출된다. 또 동시에 복사를 완료한 최초의 원고(1)은 반송용 벨트(6)에 의해 원고재치대(7)로 부터 배출된다. 다음의 원고(1)는 원고재치대(7)로부터 배출된 원고(1)와 같은 형의 마이크로 스윗치(MS2), (MS3)를 작동시키면서 이송되고, 이후 급지트래이(2)상의 원고(1)도 같은 방법으로 송출된다. 상기한 설명에 의해서 명백한 바와 같이, 급지장치에 있어서, 상기한 원동축(10)과 구동모우터(M)와를 2단 변속기능을 갖는 전동기구를 통해서 연결하고, 상기한 2단 변속 기능을 가진 전동기구를, 상기한 급지 개시신호에 의한 단시간 저속측으로 보지한 후, 고속측으로 변환되는 제어수단에 연결했기 때문에, 종이의 퇴적위치로부터 종이가 한장씩 분리되고, 급지로울러(8)와 분리로울러(4)사이에 물려 들어갈 때까지는 저속으로서, 이후엔 고속으로서 급지가 실시되고, 따라서, 분리로울러(4)에 의한 분리작용은 송출되는 종이의저속 이동중에 실시되게 되있어, 확실함은 물론 중송이 방지되고, 또 그 이후엔 고속 송출되므로 급지장치의 고속화에 장해가 되는 일은 없다.When the paper feed start signal is sent again, the relay RL 6 self-holds and the motor M rotates. At this time, since the relay RL 3 is in an inoperative state, the coil L 1 is excited by the connection of the contact S 3-2 and the normal side of the contact S 4 , and the high-speed clutch The coil L 1 is also excited in the state where the 8 is connected, and the paper feeding clutch 13 is connected. Thereby, the next document 1 which is slightly sent out by the low-speed conveyance of the paper feed roller 3 is sent out at high speed. At the same time, the first original 1 which has completed copying is discharged from the document holder 7 by the conveyance belt 6. The next original 1 is transported while operating the micro switches MS 2 and MS 3 of the same type as the original 1 ejected from the document holder 7, and then the original on the feed tray 2 ( 1) is also sent out in the same way. As apparent from the above description, in the paper feeder, the drive shaft 10 and the driving motor M are connected to each other via an electric mechanism having a two speed shift function, and the two speed shift function is provided. Since the electric mechanism was held on the low speed side for a short time by the above-described paper feed start signal, and then connected to the control means for converting to the high speed side, the paper was separated one by one from the paper deposition position, and the paper feed roller 8 and the separation roller 4 The paper feed is carried out at low speed until it is seized and then at high speed. Therefore, the separating action by the separating roller 4 is carried out during the low-speed movement of the paper to be sent out, so that it is surely prevented from feeding. In addition, since it is dispatched at a high speed thereafter, there is no obstacle to speeding up the paper feeder.
