본 고안은 모사전송기(팩시밀리)에 내장된 커터를 구동함에 있어서 하나의 정역 모터축에 서로 방향이 반대인 일방향회전클러치를 축설하여 원고급지 및 기록지의 절단작업을 자유자재로 실시할 수 있도록 함과 동시에 커터구동기구를 간략화 하고, 커터의 절단토크를 안정화하며, 원가절감등의 효과를 갖는 모사전송기의 원고급지 및 기록지 절단용 구동장치에 관한 것이다.The present invention is to drive the cutter built in the facsimile transmitter (facsimile) in one stationary motor shaft to install a one-way rotary clutch in the opposite direction to allow cutting of the document feeder and recording paper freely and At the same time, the present invention relates to a drive for cutting document feeders and recording paper for simulating a cutter driving mechanism, stabilizing a cutting torque of a cutter, and reducing costs.

종래에는 커터의 구동을 위해 별도의 직류마이크로 모터와 기어트레인 아세이의 조합이나 솔레노이드와 링크 기구등이 사용되어 왔으나 이같은 방식은 기구의 동작소음이 많이 발생할 뿐만 아니라 넓은 공간을 차지 하게 되는 불편을 감수 할수밖에 없었다.Conventionally, a combination of a separate DC micro motor and a gear train assay or a solenoid and link mechanism has been used to drive the cutter. However, this method not only generates a lot of operating noise but also takes up the inconvenience of occupying a large space. There was only.

본 고안은 상기와 같은 종래의 구동장치가 갖는 제결함을 감안하여 하나의 정역모터에 의하여 원고급지구동장치 및 기록지 절단용 구동장치를 선택적으로 구동 할 수 있도록 안출한 것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is designed to selectively drive the document feeder and the recording paper cutting drive by one stationary motor in view of the deficiencies of the conventional drive device as described above in detail according to the accompanying drawings. Is as follows.

정역 회전스텝모터(1)의 축(2)을 길게 축설하여 그 위에 일방향 클러치베어링(5)(5')을 합입한 2개의 구동풀리(3)(4)를 제동방향이 서로 반대가 되도록 설치하고, 상기 각 구동풀리(3)(4)에 원고급지용감속아이들풀리(6)와 커터구동풀리(7)를 타이밍벨트(8)(9)로 각각 연결하여 일정방향회전(정전)시에는 원고 급지장치가 구동되도록 하고, 반대방향회전(역전)시에는 기록지 절단장치가 구동되도록 한 것으로, 하나의 정역회전스텝모터(1)에 의하여 원고급지 및 기록지절단 작업을 선택적으로 실시할 수 있도록 한 것이다.The shaft 2 of the forward and reverse rotational motor 1 is elongated, and two driving pulleys 3 and 4, in which the one-way clutch bearings 5 and 5 'are incorporated, are installed so that the braking directions are opposite to each other. In addition, each of the driving pulleys (3) and (4) is connected to the document feeder deceleration idler pulley (6) and the cutter drive pulley (7) by timing belts (8) and (9), respectively. The document feeder is driven, and the recording paper cutting device is driven in the opposite direction of rotation (reverse). The document feeder and the recording paper cutting operation can be selectively performed by one forward and reverse step motor (1). will be.

이와 같이 구성된 본 고안의 작용, 효과를 설명하면, 정방향회전 및 역방향회전이 가능한 스텝모터(1)에 정전펄스가 인가되면 스텝모터(1)는 정회전을 하게되고(도면상 시계반대방향)이에 따라 구동풀리(3)가 회전을 하여 원고급지용감속아이들풀리(6)를 회전시키게되고, 이와 연결된 원고급지롤러(10)에 인하여 원고가 급지된다. 즉 구동풀리(3)에는 시계반대방향으로 회전시 제동되는 일방향크러치베어링(5)이 합입되어 있기 때문에 구동풀리(3)가 회전하여 원고급장치를 구동시키게 되는 것이다. 그러나 이때에는 동축상에 축착된 기록지 절단장치 구동용 구동풀리(4)는 회전을 하지 않아 기록지 절단작업은 이루어지지 않는다. 즉, 구동풀리(4)내에는 시계반대방향으로 회전시 제동이 해제되는 일방향크러치베어링(5')이 합입되어 있기 때문에 모터축(2)의 정회전시에는 제동이 해제되어 모터축(2)과 구동풀리(4)와는 슬립이 일어나게되므로 회전력이 기록지절단장치로 전달되지 않는 것이다.Referring to the operation and effect of the present invention configured as described above, when the electrostatic pulse is applied to the step motor 1 capable of forward and reverse rotation, the step motor 1 is rotated forward (counterclockwise in the drawing). As a result, the driving pulley 3 rotates to rotate the document feed reduction children's pulley 6, and the document is fed by the document feed roller 10 connected thereto. That is, since the driving pulley 3 is incorporated with the one-way clutch bearing 5 which is braked when rotating in the counterclockwise direction, the driving pulley 3 rotates to drive the document apparatus. At this time, however, the drive pulley 4 for driving the recording paper cutting device, which is coaxially condensed, does not rotate, and thus the recording paper cutting operation is not performed. That is, in the driving pulley 4, the one-way clutch bearing 5 'that is braked when rotated in the counterclockwise direction is incorporated, so that braking is released when the motor shaft 2 rotates in the forward direction. Since the slip occurs with the driving pulley 4, the rotational force is not transmitted to the recording paper cutting device.

한편, 원고스캐닝이 끝난뒤나, 수신기록이 끝난 뒤에 기록지 절단을 하게되는데 이때에는 정역회전스텝모터(1)가 역전신호를 받아 역회전을 하게 되고 이에 따라 구동풀리(4)가 회전하여 커터구동풀리(7)를 회전시키게되므로 이와연결된 레버(11)에 의하여 커터(12)가 하강하면서 기록지를 절단하게 되는 것이다. 즉 모터축(2)이 역회전을 하게되면 구동풀리(3)내의 일방향크러치베어링(5)은 해제되고 구동풀리(4)내의 일방향크러치베어링(5')은 제동되어 구동풀리(3)로는 모터축(2)의 회전력이 단절되며 구동풀리(4)로는 모터축(2)의 역회전력이 그대로 전달되어 커터구동풀리(7)를 시계방향으로 회전시키게 되므로 커터구동풀리(7)에 설치되어 있는 레버(11)가 하강하면서 이와 연결된 커터(12)를 잡아당기게 되므로 기록지의 절단작업이 수행되는 것이다.On the other hand, after the original scanning is finished or after the reception recording is finished, the recording paper is cut. At this time, the forward and reverse step motor 1 receives the reverse signal and reverses the rotation. As a result, the drive pulley 4 rotates to rotate the cutter drive pulley. (7) is rotated so that the cutter 12 is lowered by the lever 11 connected thereto to cut the recording paper. That is, when the motor shaft 2 rotates in reverse, the one-way clutch bearing 5 in the driving pulley 3 is released and the one-way clutch bearing 5 'in the driving pulley 4 is braked to drive the motor to the driving pulley 3. The rotational force of the shaft (2) is cut off and the reverse rotational power of the motor shaft (2) is transmitted to the drive pulley (4) as it is to rotate the cutter drive pulley (7) clockwise, which is installed in the cutter drive pulley (7) Since the lever 11 is pulled down and the cutter 12 connected thereto is pulled out, cutting of the recording paper is performed.

도면중 미설명부호, 13은 커터(12)의 정상위치를 설정해주는 커터포션 스위치이고, 14는 원고급지롤러(10)와 접설된 압압롤러이며, 15는 원고분리롤러이고, 16은 고무포드이며, 17은 원고를 압압용 스프링이고 18은 타이밍벨트이다.In the drawings, reference numeral 13 denotes a cutter position switch for setting the normal position of the cutter 12, 14 is a pressure roller connected to the document feed roller 10, 15 is a document separation roller, and 16 is a rubber pod. 17 is the spring for pressing the document and 18 is the timing belt.

이와 같이 본 고안은 하나의 정역모터를 사용하여 원고급지 및 기록지의 절단작업을 선택적으로 수행토록 함으로서 커터를 작동시키기 위한 구동기구를 단순화함과 동시에 기구의 소음을 줄이고 최소공간으로 본 장치를 구현할 수 있는 그 실사용 가치가 일층고양된 신규의 고안인 것이다.As such, the present invention allows the cutting of the document feeder and the recording paper selectively using a single stationary motor, thereby simplifying the driving mechanism for operating the cutter, reducing the noise of the mechanism, and realizing the device with the minimum space. It is a new design with its practical value.
