The developing unit 3, the cleaning unit 4, and the optical system 5 are provided at both sides and the upper and lower sides of the drum 2 provided in the middle of the main body 1. ) And a separate transfer plate 6, and a fixing unit 8 is installed at one side of the cleaning unit 4, and a discharge unit 10 having a discharge roller 9 arranged on the outside thereof is hinged. It is installed so that rotation is possible.

제1도에서 7은 급지 카세트, 12는 레지스터롤러, 13은 대전코트나, 14는 전사코로나부를 보인 것이고, 15는 용지 가이드를 보인 것이다.In FIG. 1, 7 is a paper cassette, 12 is a register roller, 13 is a charging coat, 14 is a transfer corona portion, and 15 is a paper guide.

본 고안은 이러한 레이저 빔 프린터에서 드럼(2)을 구동시키기 위한 장치에 관한 것으로 이하, 제2도 및 제5도에 의하여 상세히 설명하면 다음과 같다.The present invention relates to an apparatus for driving the drum (2) in such a laser beam printer will be described in detail below with reference to FIG. 2 and FIG.

양측 프레임(16)(16')에 부시(17)(17')가 고정되어 그 부시(17)(17')에 구동축(18)의 양측부가 지지되고 구동축(18)의 중간부에는 지지마개(19)(20)가 양단부에 고정된 드럼(2)이 고정된 것에 있어서, 구동축(18)이 삽입되는 축공(21a)을 갖는 구동판(21)의 축공(21a) 일측에 나사공(21b)을 연통되게 형성하여 세트스크류(22)를 체결하고 축공(21a) 상측부에 형성한 삽입공(21c)에 구동핀(23)을 삽입하는 동시에, 축공(21a)과 대응되는 축공(24a)을 갖는 판스프링(24)의 하측부를 구동판(21)의 하측부에 양측으로 형성한 나사공(21d)에 체결용 스크류(25)로 고정하여 판스프링(24)이 구동핀(23)을 탄력 지지하게 하며, 지지마개(20)의 축지부(20a) 양측에는 상기 구동핀(23)이 걸리는 리브(20b)를 형성한 것으로 도면중 미설명부호 26은 구동모터, 27, 28은 구동축(18)과 구동모터축(26')에 각각 고정되어 맞물리는 기어를 보인 것이다.Bushes 17 and 17 'are fixed to both frames 16 and 16' so that both sides of the drive shaft 18 are supported by the bushes 17 and 17 ', and a support stopper at the middle of the drive shaft 18. (19) The screw (21b) is provided on one side of the shaft hole (21a) of the drive plate (21) having the shaft hole (21a) into which the drive shaft (18) is inserted, in which the drum (2) having both ends fixed. ) Is formed in communication with the set screw 22, and the driving pin 23 is inserted into the insertion hole 21c formed in the upper portion of the shaft hole 21a, and the shaft hole 24a corresponding to the shaft hole 21a is formed. The lower side of the leaf spring (24) having a fixed to the screw hole (21d) formed on both sides in the lower portion of the drive plate 21 by fastening screw 25 to the plate spring (24) to drive the drive pin (23) Resilient support, ribs (20b) to the driving pin 23 is formed on both sides of the support portion (20a) of the stopper 20, reference numeral 26 in the drawing is a drive motor, 27, 28 is a drive shaft ( 18) and drive motor shaft 26 ' It shows an interlocking fit control gear.

이와 같이 된 본 고안을 조립하는 경우에는 일측 프레임(16)의 부시(17)에 구동축(18)이 고정되고 서로 맞물리는 기어(27)(28)가 구동축(18)과 모터축(26')에 각각 고정되어 있는 상태에서 구동판(21)과 구동핀(23) 및 판스프링(24)을 결합하여 구동축(18)에 삽입하고 구동판(21)의 나사공(21b)에 끼워지는 세트스크류(22)를 조여 체결한다.When assembling the present invention as described above, the drive shaft 18 is fixed to the bush 17 of one frame 16 and the gears 27 and 28 meshing with each other are the drive shaft 18 and the motor shaft 26 '. The set screw fitted to the drive shaft 18 by coupling the drive plate 21, the drive pin 23 and the leaf spring 24 in the state fixed to each other and fitted into the screw hole 21b of the drive plate 21 Tighten (22) to tighten.

이와 같이 결합한 상태에서 지지마개(19)(20)가 양단부에 고정된 드럼(2)을 구동축(18)에 삽입하고 부시(17')가 고정된 타측프레임(16')을 외측에서 삽입하여 조립한다.Inserting the drum 2, the support stopper 19, 20 is fixed to both ends in the drive shaft 18 in the coupled state, and the other frame 16 'fixed with the bush 17' is inserted from the outside. do.

이아 같이 조립이 완료된 상태에서 구동핀(23)은 제5(a)도에 도시한 바와 같이 지지마개(20)의 리브(20b)외측의 공간부에 위치하게 되거나, 제5(b)도에 도시한 바와 같이 지지마개(20)의 리브(20b)에 걸려 판스프링(24)을 외측으로 밀어 휘어지게 하는 상태로 조립된다.Thus, in the state where the assembly is completed, the driving pin 23 is located in the space outside the rib 20b of the support plug 20 as shown in FIG. 5 (a), or in FIG. 5 (b). As shown in the figure, the ribs 20b of the support plug 20 are assembled in a state in which the leaf springs 24 are pushed outward.

제5(a)도의 상태로 조립된 경우에 구동모터(26)의 구동력을 기어(27)(28)로 전달받아 구동축(18)이 회전하면 구동축(18)에 세트스크류(22)로 체결되어 있는 구동판(21)이 회전하게 되므로 구동판(21)에 끼워져 있는 구동판(23)이 지지마개(20), 리브(20b)의 측면에 결려 지지마개(20)와 견고하게 접착되어 있는 드럼(2)이 회전된다.When assembled in the state of FIG. 5 (a), when the driving force of the driving motor 26 is transmitted to the gears 27 and 28 and the driving shaft 18 is rotated, the set screw 22 is fastened to the driving shaft 18. The driving plate 21 is rotated so that the driving plate 23 fitted to the driving plate 21 is firmly adhered to the supporting plug 20 and the side of the rib 20b to the supporting plug 20. (2) is rotated.

제5(b)도의 상태로 조립된 경우에는 판스프링(24)이 구동판(23)을 밀고 있으므로 구동판(21)이 구동축(18)의 회전에 따라 회전하면 구동핀(23)이 리브(20b)의 측면으로 밀려들어가 걸리게 되어 드럼(2)이 회전되어진다.When assembled in the state of FIG. 5 (b), since the leaf spring 24 pushes the driving plate 23, when the driving plate 21 rotates according to the rotation of the driving shaft 18, the driving pin 23 is ribbed ( The drum 2 is rotated by being pushed to the side of 20b).

한편, 필요에 따라 드럼(2)을 교환하고자 하는 경우에는 타측 프레임(16')을 먼저 분리시키고 드럼(2)을 간단 용이하게 분리할 수 있으며 새로운 드럼을 구동축(18)에 삽입 장착하고 타측 프레임(16')을 결합하는 간단한 작업에 의하여 조립이 완료된다.On the other hand, if the drum 2 is to be replaced as necessary, the other frame 16 'can be separated first, and the drum 2 can be easily detached, and a new drum is inserted into the drive shaft 18 and mounted on the other frame. Assembly is completed by a simple operation of engaging the 16 '.

상술한 바와 같이 된 본 고안은 드럼의 교환작업이 간단 용이할뿐 아니라, 구동판에 끼위져 있는 구동핀이 드럼에 고정된 지지마개의 리브에 걸려 드럼이 회전되므로 정확한 구동을 기할 수 있는 이점이 있다.The present invention as described above is not only easy to replace the drum, but also the drive pin pinned to the drive plate is caught on the rib of the support plug fixed to the drum is the advantage that can be accurately driven because the drum is rotated have.
