Sensors (S-1, 2, 3, 4, 5) were installed in (4), respectively, and the separating display board (1) located at the lower part of the drum couples the hinge piece (15) to the rear end thereof, On the bottom, the cam 20 which is driven and controlled by a separate driving and operating device is contacted and installed, and as the cam 20 is rotated, the tip of the separation transfer plate 1 is lifted around the hinge pin 15. To descend.

그리고 상기 캠(20)을 회전시키기 위한 구동장치는 도면 제2,3,4도에서와 같이 분리전사판(1)의 하부에서 양측이 베어링(도시하지 않음)지지 결합된 캠샤프트(19)의 일측에 종동기어(21)가 결합설치되고, 그 하방의 후레임에 고정 부착시킨 브래킷트(26)에는 보조샤프트(25)를 설치하여 상기 종동기어(21)와 연결되는 구동기어(22)와 웜휠(22-a)을 일체로 결합설치 하였으며, 그 하부에는 상기 웜휠 구동용 워엄(24)을 구비한 구동모터(23)가 고정설치 되었다.In addition, the driving device for rotating the cam 20 includes a cam shaft 19 having both sides supported by bearings (not shown) at the lower portion of the separation transfer plate 1 as shown in FIGS. 2, 3, and 4. A driven gear 21 is coupled to one side, and an auxiliary shaft 25 is installed on a bracket 26 fixedly attached to a frame below the drive gear 22 and a worm wheel connected to the driven gear 21. (22-a) was integrally installed, and the lower portion of the drive motor 23 having the worm wheel 24 for driving the worm wheel was fixedly installed.

또한, 상기 구동장치를 제어하기 위한 작동장치를 보인 상기 브래킷트(26)의 일측면에 2개의 센서용 마이크로스위치(S-6)(S-7)가 내외측으로 나란하게 고정설치되고, 상기 캠샤프트(19)의 일측단부에는 외주면으로서 상기 스위치(S-6)(S-7)의 터치부(61)(71)와 접촉 온/오프 시키는 작동원판(27)이 설치되었으며, 상기 작동원판(27)의 외주면에는 90C위상차를 가지고 스위치 오프동작용 내, 외측 오목부(271)(272)를 형성 시켜서 된것이다.In addition, two sensor microswitches (S-6) (S-7) are fixedly installed side by side inward and outward on one side of the bracket 26 showing the operating device for controlling the drive device, and the cam One side end of the shaft 19 is provided with an operating disk 27 for turning on / off contact with the touch units 61 and 71 of the switches S-6 and S-7 as an outer circumferential surface. On the outer circumferential surface of 27), outer recesses 271 and 272 are formed in the switch-off action with a 90C phase difference.

이상과 같이 구성된 본 고안의 작동상태를 보면 다음과 같다.Looking at the operating state of the present invention configured as described above are as follows.

프린터에 전원을 온시키면 각부위에 센서(S-1...5)들이 각해당 부품 즉, S-1은 종이카트리지(3)의 준비상태, S-2는 배지부커버(8)가 닫힌상태, S-3는 드럼(10)의 준비상태, S-4는 크리닝부(6) 준비상태, S-5는 현상부(4)의 준비상태를 확인하게 된다(도면 제6(a)도 참조) 상기 각 센서가 O.K시에는 구동모터(23)를 동작시켜 그 동력이 웜(24)-웜휠(22-a)-구동기어(22)-종동기어(21)-캠새프트(19)를 통해 캠(20)에 전달 회전되므로서, 그에 밀려 상기 분리전사판(1)의 선단부가 후단의 힌지핀(15)를 중심으로 회전 상승 되는 것이다. (도면 제7(a)도 참조) 이때, 상기와 같은 동작으로 분리전사판(1)을 올리는 동안에는 도면 제5(b)도와 같이 캠샤프트(19) 일측에 설치된 작동원판(27)의 외주면이 마이크로스위치(S-6)(S-7)의 터치부(61)(71)와 동시접하여 누른 상태로 회전하면서, 도면 제6(b)도와 같은 체크프로그램으로 상기 각 센서(S-1....5)의 상태를 확인하여 완전히 들어올려 도면 제5(c)도와 같이 내측오목부(271)에 내측 마이크로 스위치의 터치부(61)가 삽입된 상태로 정지하게 된다.When the printer is turned on, the sensors (S-1 ... 5) on each part of each part, that is, S-1 is the ready state of the paper cartridge (3), S-2 is the discharge cover (8) is closed, S-3 checks the ready state of the drum 10, S-4 checks the ready state of the cleaning unit 6, and S-5 checks the ready state of the developing unit 4 (see also FIG. 6 (a)). When each sensor is OK, the drive motor 23 is operated so that its power is cam via the worm 24, the worm wheel 22-a, the drive gear 22, the driven gear 21, and the cam shaft 19. As it is transmitted to and rotated by 20, the front end portion of the separation transfer plate 1 is pushed up and rotates about the hinge pin 15 of the rear end. (See also FIG. 7 (a).) In this case, the outer peripheral surface of the operation disk 27 installed on one side of the camshaft 19 as shown in FIG. Each sensor (S-1 .. S. .. with a check program as shown in FIG. 6 (b) while rotating in a pressed state simultaneously with the touch parts 61 and 71 of the micro switches S-6 and S-7. .5) and checks the state completely, it is lifted up completely and stops with the touch part 61 of the inner micro switch inserted in the inner recess 271 as shown in FIG. 5 (c).

이런 상태에서 어느 센서 하나라도 변화가 있으면 이 신호가 구동모터(23)로 전달되어 캠샤프트(19)의 캠(20)을 회전시켜 주므로서 분리전사판(1)의 선단부를 하방으로 내린다(도면 제7(b)도 참조), 내리는 도중에는 체크프로그램을 검사하여 상황변화에 대처 하면서 완전히 내려 작동원판의 외측 오목보(272)내에 외측 마이크로스위치(S-7)의 터치부(71)가 삽입된 상태로 정지하게 된다.In this state, if any sensor changes, this signal is transmitted to the driving motor 23 to rotate the cam 20 of the camshaft 19, thereby lowering the tip of the separation transfer plate 1 downward (Fig. 7 (b)), during the lowering, the check program is inspected and the touch unit 71 of the outer microswitch S-7 is inserted into the outer concave beam 272 of the working disk while being completely lowered while responding to the change of the situation. It will stop in the state.

일예를 들어 Jam이 발생하면 내부에 낀 종이를 제거해야 하는데 드럼(10)과 분리전사판(1) 사이의 간격이 좁아서 종이를 그냥 잡아 빼면 드럼면의 손상을 가져온다.For example, when a jam occurs, the paper jammed inside should be removed, but the gap between the drum 10 and the separation transfer plate 1 is narrow, and if the paper is simply pulled out, damage to the drum surface may occur.

따라서 배지부커버(8) 열거나 종이카트리지(3)를 빼내게 되면 해당 센서의 작동에 의해 상기와 같은 동작으로 분리전사판(1)의 선단부가 하강하면서 그 사이의 간격이 넓어져 종이를 쉽게 빼낼수 있는 것이다.Therefore, when the discharge cover (8) is opened or the paper cartridge (3) is pulled out, the front end of the separation transfer plate (1) is lowered by the operation of the sensor as described above, and the gap therebetween becomes wider to remove the paper easily. It can be.

이상과 같이 구성되고 작동되는 본 고안은 일체형 레이져 빔 프린터에 있어서 정상가동시 외부의 조건 변화를 센서로서 감지하여 분리전사판을 자동적으로 승하강시켜줌에 따라, 드럼 표면의 손상방지는 물론이고, 드럼의 수명을 연장 할 수 있으며, 분리전사판이 자동으로 승하강동작 되므로서 사용자에게 종래의 수동조작 방식에 비해 사용 및 조작상의 편리성을 제공할 수 있으며, 종래장치의 문제점을 해결할 수 있는 특출한 효과가 있는 것이다.The present invention, which is constructed and operated as described above, detects a change in external conditions as a sensor in an integrated laser beam printer and automatically raises and lowers the separation transfer plate, thereby preventing damage to the surface of the drum. The service life can be extended, and the separate transfer plate is automatically lifted up and down to provide the user with convenience in use and operation compared to the conventional manual operation method. It is.
