본 고안은 중속 전자복사기의 광학계 구동장치에 관한 것으로, 특히 복사기 본체의 상측 외곽부에 수개의 풀리를 축착하여 구동모우터의 구동력이 제1밀러지지체 및 제2, 제3밀러지지체의 양측에 동일하게 전달되게 설치함으로써 하나의 구동모우터로 안정한 중속복사를 할 수 있게한 구동장치에 관한 것이다.The present invention relates to an optical drive device of a medium speed electron copying machine. In particular, several pulleys are condensed on the upper outer portion of the copier main body so that the driving force of the driving motor is the same on both sides of the first mirror support and the second and third mirror support. The present invention relates to a drive device that enables stable medium speed copying with a single drive motor.
종래에 사용되는 전자복사기는 제1도에 도시한 바와 같이 복사기본체(1)의 양측벽(2)(2')사이에 설치한 안내봉(3)과 안내레일(4)을 타고 이송되는 제1밀러지지체(5)와 제2, 제3밀러지지체(6)를 구동모우터(7)의 풀리(8)에 일부분이 감긴 와이어로우프(9)에 연결하여 구동하도록 되어 있는 바, 풀리(8)에 감긴 와이어로우프(9)이 한쪽 가닥은 중간풀리(10)(10') 및 제2, 제3밀러지지체(6)의 풀리(11)를 거쳐 복사기 본체(1)의 일측벽(2)에 그 단부를 고정하고 풀리(10')(11)사이의 와이어로우프(9)에는 제1밀러지지체(5)의 고정편(12)를 고정하는 한편, 풀리(8)에 감긴 와이어로우프(9)의 다른쪽 가닥은 중간풀리(10)(10'')를 거치고 제2, 제3밀러지지체(6)의 풀리(11)를 거친 후 복사기본체(1)의 타측벽(2')에 그 단부를 고정하여 구동시키는 구조로 되어 있다.As shown in FIG. 1, a conventional electronic copying machine is transported on a guide rod 3 and a guide rail 4 installed between both side walls 2 and 2 'of the radiation main body 1. 1, the pulley 8 is driven by connecting the mirror support 5 and the second and third mirror support 6 to the wire rope 9 wound around the pulley 8 of the driving motor 7. One side of the wire rope (9) wound on the one side wall (2) of the copier main body (1) via the middle pulley (10) (10 ') and the pulley (11) of the second and third mirror support (6) The end portion of the first mirror support 5 is fixed to the wire rope 9 between the pulleys 10 'and 11, while the wire rope 9 wound around the pulley 8 is fixed. The other strand of) passes through the intermediate pulley (10) (10 '') and through the pulley (11) of the second and third mirror support (6) and then to the other side wall (2 ') of the radiation base (1) It has a structure in which the end is fixed and driven.
그러나, 이러한 장치는 저속복사(A4기준 20-25매/분정도)에만 적합하도록 한 것으로, 이 장치로서 중속복사하려면 제4도와 같이 진동이 심하여 해상력이 매우 떨어져 양호한 복사를 기하지 못하는 문제점이 있었다.However, such a device is only suitable for low speed copying (about 20-25 sheets / minute based on A4), and this device has a problem in that the medium speed copying is severely vibrated as shown in FIG. .
따라서, 이러한 문제점을 해소하여 중속 복사에 적합하도록 한 구동장치가 알려지고 있는 바, 이는 제2도에 도시한 바와같이 복사기본체(1)의 양측벽(2)(2')사이에 안내봉(3)(3')을 설치하여 제1밀러지지체(5)와 제2밀러지지체(6)가 안내봉(3)(3')을 타고 이송될 수 있게하고, 상기 제1도에 도시한 바와 같은 구동장치를 양측에 동일하게 설치하여 양쪽에서 동시에 구동력을 걸어줌으로써 진동문제를 해소하고 안정된 복사를 중속으로 할 수 있도록 한 구조로 되어 있으며, 이와같은 구동장치는 구동모우터(7)를 구동시켜 그 구동력이 와이어로우프(9)를 통해 전달되면 와이어 로우프(9)에 고정되거나 감겨있는 제1밀러지지체(5)와 제2, 제3밀러지지체(6)가 안내봉(3)(3')을 타고 이송하게 된다.Therefore, a driving device that solves this problem and is suitable for medium speed radiation is known. As shown in FIG. 2, a guide rod (between the side walls 2 and 2 'of the radiation base body 1) is provided. 3) (3 ') so that the first mirror support (5) and the second mirror support (6) can be transported on the guide rods (3) (3'), as shown in FIG. The same drive device is installed on both sides to apply driving force at both sides to solve the vibration problem and to make stable radiation at medium speed. Such a drive device drives the drive motor (7). When the driving force is transmitted through the wire rope 9, the first mirror support 5 and the second and third mirror support 6 fixed or wound on the wire rope 9 are guide rods 3, 3 ′. Will be transported by air.
그러나, 이러한 구동장치는 양측 구동장치의 조립공차, 제작공차 및 모우터의 특성등으로 인하여 정도관리가 어렵고 양측 구동모우터(7)가 약간의 특성차이가 있거나, 양측 와이어로우프(9)의 신율차이 혹은 각종 부품들의 제작공차로 인한 조립상의 오차등 여러가지 요인으로 인하여 양측 와이어로우프(9)의 속도차이가 있을때 제1밀러지지체(5)와 제2, 제3밀러지지체(6)의 수평이동에 스틱슬립(stick slip)등의 현상이 유발되는 문제점들을 해소하기 위하여 구동모우터(7) 각각에 속도검지장치를 설치하여 속도를 각기 검지하고 속도차에 따른 크로스로우프콘트롤(closed loop control)등의 제어를 행하여야 하는 복잡한 수단이 요구될 뿐아니라, 2개의 구동모우터와 그의 사용부품수가 증가하고, 제작원가가 상승되는 등의 결함이 있었다.However, these driving devices are difficult to control due to assembly tolerances, manufacturing tolerances, and characteristics of the motors of both driving devices, and the two driving motors 7 have slight characteristic differences, or the elongation of both wire ropes 9. Due to various factors such as assembly errors due to differences or manufacturing tolerances of various parts, there is a difference in the horizontal movement of the first mirror support 5 and the second and third mirror supports 6 when there is a speed difference between the two wire ropes 9. In order to solve the problems caused by stick slip, the speed detection device is installed in each of the driving motors 7 to detect the speeds individually and to close the loop control according to the speed difference. In addition to requiring complicated means for performing control, there are defects such as an increase in the number of two drive motors and their use parts, and an increase in manufacturing cost.
본 고안은 이러한 종래 구동장치의 결함을 해소하기 위하여 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve the defects of the conventional driving device, which will be described in detail with reference to the accompanying drawings.

Fixing pieces 26, 26 'and pulleys 27, 27' are installed at both ends of the first mirror support 24 and the second mirror support 25, which are transported by air. The main body 21 in which the wire rope 30 wound around the pulley 29 is fixed to the fixing piece 26 via the intermediate pulleys 31, 32, 32 ′ and wound around the pulley 27. Pulleys 33, 34, 35 and 36 of the upper corners of the pulleys 27 and 38 are fitted with shaft pins 37, 38, 39 and 40, respectively. One strand of the wire rope 30 wound around the wire rope 30 is fixed to the fixing piece 26 'of the first mirror support 24 via the pulleys 33 and 34, and the pulleys of the second and third mirror support 25 are fixed. And the end of the wire rope 30 wound around the pulley 27 and fixed to the one side wall 22 'after being wound on the side wall 22'. Hit will prevent fixed not to move in the second, third Miller other side wall 22, the rear end portion wound around the pulley (27 ') of the support (25).
이와같이 된 본 고안은 일측벽(22')에 일단부가 고정된 와이어로우프(30)가 풀리(27')에 감기고 고정편(26')에 고정되며 이어서 풀리(34)(33)(27)를 거쳐 고정편(26)에 고정되고 또 풀리(32')(31)를 거쳐 구동모우터(28)의 풀리(29)에 감긴 후, 다시 풀리(31)를 거쳐 풀리(32) 및 풀리(287)(35)(36)(27')에 감긴 후 타측벽(22)에 타단부가 고정되어 있고, 상기 제2, 제3밀러지지체(25)의 풀리(27)(27')는 그 지지체(25)를 따라 좌우 이동하지만 나머지 풀리들은 설치된 위치에서 회동하여 와이어로우프(30)의 운동을 안내하도록 되어 있으므로, 구동모우터(28)를 구동시켜 풀리(29)가 시계방향으로 회전하면 제3도에 도시한 화살표 방향으로 구동력이 전달되는 바, 복사기 외곽에 설치된 풀리(33)(34)(35)(36)에 의하여 모우터(28)의 구동력이 반대측에도 전달되고 제1밀러지지체(24)의 고정편(26)(26')과 제2, 제3밀러지지체(25)의 풀리(27)(27')를 통하여 각 지지체(24)(25)의 양측에 동시에 구동력이 작용되어 각 지지체(24)(25)가 안정되게 이송할 수 있게 된다. 한편, 구동모우터(28)의 역방향 회전에는 도시한 화살표의 반대로 구동된다.In the present invention, the wire rope 30 having one end fixed to one side wall 22 'is wound around the pulley 27' and fixed to the fixing piece 26 ', and then the pulleys 34, 33 and 27 are Fixed to the fixed piece 26 and wound around the pulley 29 of the drive motor 28 via the pulleys 32 'and 31, and then pulley 32 and pulley 287 via the pulley 31 again. The other end is fixed to the other side wall 22, and the pulleys 27 and 27 'of the second and third mirror supports 25 are supported by While the left and right move along the (25) to guide the movement of the wire rope 30 by rotating in the installed position, the drive motor 28 to drive the pulley 29 is rotated in the clockwise direction third As the driving force is transmitted in the direction of the arrow shown in the figure, the driving force of the motor 28 is also transmitted to the opposite side by the pulleys 33, 34, 35 and 36 installed on the outer side of the copier and the first mirror support 24 ) Fixed piece (26) 26 ') and the driving force is simultaneously applied to both sides of each of the supports 24 and 25 through the pulleys 27 and 27' of the second and third mirror supports 25, so that each support 24 and 25 is applied. It can be transported stably. On the other hand, the reverse rotation of the drive motor 28 is driven opposite to the arrow shown.
상기한 바와 같은 본 고안은 하나의 구동모우터의 구동력이 각 밀러지지체(24)(25)의 양측에 동일하게 전달 되어 각 밀러지지체(24)(25)가 안정되게 이송될 수 있으므로, 장치가 간소화되고 작동중 진동 및 스틱슬립등의 현상이 해소되는 이점이 있다. 따라서 본 고안은 제품의 원가를 절감하면서 신뢰성을 상승시키는 이점이 있다.According to the present invention as described above, the driving force of one driving motor is equally transmitted to both sides of each mirror support 24 and 25 so that each mirror support 24 and 25 can be stably transferred. Simplified and there is an advantage that the phenomenon such as vibration and stick slip during operation is eliminated. Therefore, the present invention has the advantage of increasing the reliability while reducing the cost of the product.
