본 발명은 레이저 비임프린터 사용시 입력데이터의 크기와 출력용지가 부합되지 않을 경우 이를 조정하여 사용자의 용지 크기에 맞춰 출력할 수 있도록 한 레이저 비임프린터의 광학부 이동장치에 관한 것이다.The present invention relates to an optical unit moving device of a laser beam printer to adjust the size of the input data and the output paper when using the laser beam printer, so that it can be output according to the user's paper size.

종래에는 데이터(DATA) 크기가 A3인 경우 A4크기의 레이저 비임프린터에서 출력할 수 없고 A5사이즈의 데이터를 A4크기의 용지로 출력하려면 일단 A5로 출력한 후 복사기등으로 확대하여 A4로 만들어야 하므로 중간과정 등으로 인해 번거로웠다.Conventionally, when the data size is A 3 , it cannot be output from the laser beam imprinter of A 4 size. If you want to output A 5 size data to A 4 size paper, output it to A 5 and then enlarge it with a copy machine. I had to make A 4 , so it was cumbersome because of the intermediate process.

따라서 본 발명은 상기한 바와 같은 제반결점을 해소코자 레이저 비임프린터의 광학부를 이동시킬 수 있도록 형성하여 감광드럼과의 거리를 조정할 수 있도록 하므로서 감광드럼에 비쳐지는 빛의 폭을 축소, 확대시켜 사용자의 용지 폭에 맞게 출력될 수 있도록 하는데 그 목적이 있는 것이다.Therefore, the present invention is formed to move the optical portion of the laser beam non-printer to solve the above-mentioned defects to adjust the distance to the photosensitive drum, thereby reducing the width of the light reflected on the photosensitive drum by expanding the user's Its purpose is to ensure that the paper is printed according to its width.

이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.

광학부(30) 전체를 하나의 이동받침대(2)위에 장설하되, 이동받침대(2)에는 롤러바퀴(3)(3')(3)(3')를 장착하고 롤러바퀴(3)(3') 또는 (3)(3') 사이에 있는 이동받침대(2) 저면측에 랙기어부(4)를 형성하고 그에 정역회전 모터(6)로 구동되어 기어(5)를 연결 연동되게 부설시킨 레이저 비임프린터의 광학부 이동장치이다. 미설명보호 20은 광학부(30)의 레이저 다이오드이고 21은 콜리메이터렌즈이고 22는 빔변조플리즘 23은 프리즘 24는 플리곤미러 25 F. θ렌즈이다.The whole optical part 30 is installed on one movable support 2, but the roller supports 3, 3 ', 3', 3 'are mounted on the movable support 2, and the roller wheels 3, 3 ') Or (3) (3') to form the rack gear portion (4) on the bottom side of the movable support (2) and is driven by the reverse rotation motor (6) to install the gear (5) connected interlocked It is an optical unit moving device of a laser beam printer. Unexplained protection 20 is a laser diode of the optical unit 30, 21 is a collimator lens, 22 is a beam modulation prism 23, a prism 24 is a polygon mirror 25 F. θ lens.

이와 같은 구성된 본 발명의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.

용지가 작을때는 기기본체 외부측에 장설시킨 작동노브 등으로 모터(6)를 구동시키면 기어(5)가 회동하여 이에 맞물린 이동받침대(2)의 랙기어부(4)를 전진이동시키게 되므로 이동받침대(2) 상측에 장설시킨 광학부(30)와 감광드럼(1) 사이의 거리가 단축되어 레이저 다이오드의 빛 발사폭의 작아져 작은 용지크기에 맞춰 복사되어 출력되는 것으로 이동거리는 프로그램에 맞게 설치한 리미트스위치의 작동으로 조정하게 되는 것이다. 용지가 클때는 모터(6)를 역방향으로 구동시켜 모터(6) 기어(5)가 이동 받침대(2)를 후진시켜 감광드럼(1)과의 거리가 확대되어 빛 발사폭이 커지게 되므로 큰 용지로 출력할 수 있게 되는 것이다.When the paper is small, when the motor 6 is driven by an operation knob installed on the outside of the main body of the machine, the gear 5 rotates to move the rack gear part 4 of the movable support 2 engaged therefor. (2) The distance between the optical unit 30 placed on the upper side and the photosensitive drum 1 is shortened, so that the light emitting width of the laser diode is reduced, which is copied and output according to the small paper size. It is controlled by the operation of the limit switch. When the paper is large, the motor 6 is driven in the reverse direction so that the gear 6 of the motor 6 retreats the moving pedestal 2 so that the distance from the photosensitive drum 1 is enlarged to increase the light emission width. Will be printed.

이상과 같은 본 발명은 용지조정을 위해 중간복사과정을 생략할 수 있고 간단한 구성으로 용지폭을 출력용지폭에 알맞게 조절할 수 있어 가격 경쟁력을 향상시키고, 기기의 품질을 높일 수 있는 유용한 발명인 것이다.As described above, the present invention can omit the intermediate copying process for adjusting the paper and can adjust the paper width to the output paper width with a simple configuration, thereby improving the price competitiveness and improving the quality of the device.
