본 고안은 전자 사진 응용 기기의 토너(Toner)보급 장치에 관한 것으로 특히 간단한 구성으로 토너의 보급을 원활히하고, 진동에 의한 소음을 방지하도록한 전자 사진 응용 기기의 코너 보급 장치에 관한 것이다.The present invention relates to a toner dispensing apparatus of an electrophotographic application apparatus, and more particularly, to a corner dispensing apparatus of an electrophotographic application apparatus which facilitates dispensing of toner with a simple configuration and prevents noise caused by vibration.
종래의 토너 보급 장치에 제1도에서 보는 바와 같이, 현상기몸체(Sleeve) (1)의 상측수납부 (1b)와 하측 현상부(1c)사이에 두개의 돌기(9a)가 형성된 호퍼(9)를 회전 가능하게 설치하고, 상단을 수납부(1b)의 경사면에 힌지 (10a)(10'a)로 고정시킨 진동판 (10)(10')의 내측에 압축스프링(13)(13')을 탄설하여 하단을 호퍼(9)에 접촉시키며, 현상부(1c)에는 두개의 믹싱 블래드(Mixing Blade) (3)(3')를 회전 가능하게 설치하고, 닥터 블래드(Doctor Blade)(8)가 설치된 일측의 배출구(1a)에는 자석(5)이 내장된 슬리브(6)을 회전 가능하게 설치하여 외부의 드럼(7)과 일정 간격을 유지시켰던 것으로 사용자가 수납부(1b)상단에 덮개판(2)을 열어 토너를 넣게 되면 이 토너는 진동판(10)(10')과 호퍼(9)에 걸려 아래로 내려가지 못한다.As shown in FIG. 1 of the conventional toner replenishing apparatus, a hopper 9 having two projections 9a formed between the upper storing portion 1b and the lower developing portion 1c of the developer body 1 is formed. And the compression springs 13 and 13 'inside the diaphragms 10 and 10' where the upper end of the diaphragm is fixed to the inclined surface of the housing portion 1b by the hinges 10a and 10'a. The bottom surface is brought into contact with the hopper 9, and two mixing blades 3 and 3 'are rotatably installed in the developing part 1c, and a doctor blade 8 At the outlet 1a on one side of which is installed a rotatable sleeve 6 having a magnet 5 installed therein to maintain a predetermined distance from the external drum 7, the user covers the upper portion of the housing 1b. When the plate 2 is opened to put the toner, the toner is caught by the diaphragms 10, 10 'and the hopper 9 and cannot be lowered down.
이후 사용자가 기기를 동작시키게 되면, 회전하는 호퍼(9)의 돌기(9a)가 진동판(10)(10')을 교대로 눌러주게 됨으로서 진동판(10)(10')이 압축 스프링(13) (13')의 탄성력에 의해 힌지(10a)(10'a)를 중심으로 상, 하 운동을 하게 되어 토너가 호퍼(9)와 진동판(10) (10')사이의 틈을 통해 현상부(1c)로 낙하된 다음 믹싱 블래드(3) (3')에 의해 골고루 섞인후 자력의 영향으로 슬리브(6)에 달라 붙어 드럼(7)표면에 현상 되었던 것이다.Afterwards, when the user operates the device, the projections 9a of the rotating hopper 9 alternately press the diaphragms 10 and 10 'so that the diaphragms 10 and 10' are compressed springs 13 ( 13 ') moves up and down about the hinges 10a and 10'a by the elastic force of the toner, and the toner is developed through the gap between the hopper 9 and the diaphragm 10 and 10'. ) And then mixed evenly by the mixing blades (3) (3 ') and stuck to the sleeve (6) under the influence of magnetic force and developed on the surface of the drum (7).
따라서 이와 같은 장치는 호퍼(9)와 진동판(10)(10')사이에서 토너가 고착화될 경우 토너가 낙하를 막게 되어 기기의 성능을 떨어뜨리고 진동판(10)(10')이 돌기(9a)와 접촉하면서 소음을 발생하였던 것이다.Therefore, such a device prevents the toner from dropping when the toner is fixed between the hopper 9 and the diaphragm 10, 10 ', thereby degrading the performance of the machine and causing the diaphragm 10, 10' to protrude 9a. It was making noise when contacting with.
본 고안은 이러한 문제점을 해결하기 위하여 안출한 것으로서 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention is devised to solve such a problem, and will be described in detail with reference to the accompanying drawings.
제2도에서 보는 바와 같이 현상기 몸체(1)상단에 토너를 주입시킬 수 있도록 덮개판(2)을 설치하고, 양측면의 지지축(1d)(1e)에 믹싱 블래드(3)를 설치하되 일측의 지지축(1e)을 외부로 돌출시켜 회전 가능하도록 믹싱 기어(11)를 착설하며 제3도와 같이 일측의 경사면에 자성체인 진동판(4)의 상단을 스크류(14)로 체결하고 외부의 드럼(7)과 일정 간격이 유지되도록 자석(5)이 내장된 슬리브(6)의 양측 고정축(6a) (6b)을 닥터 블래드(8)가 부착된 하단의 배출구(1a)측면에 고정 설치하여 슬리브(6)과 진동판(4)의 하단을 일정 간격 유지시키며, 외부로 돌출된 슬리브(6)의 일측고정축(6b)에 믹싱기어(11)와 맞물리도록 구동기어(12)를 착설한다.As shown in FIG. 2, the cover plate 2 is installed to inject the toner into the upper part of the developer body 1, and the mixing blade 3 is installed on the support shafts 1d and 1e on both sides. Mixing gear 11 is installed so as to be rotatable by protruding the support shaft (1e) of the outside, and fasten the upper end of the diaphragm (4) of the magnetic body to the inclined surface of one side with a screw 14 as shown in FIG. 7) the fixed shaft (6a) (6b) of both sides of the sleeve (6) with the magnet (5) is fixed to the side of the outlet (1a) of the lower end to which the doctor blade (8) is attached The lower end of the sleeve 6 and the diaphragm 4 is maintained at regular intervals, and the driving gear 12 is installed to engage with the mixing gear 11 on one side fixed shaft 6b of the sleeve 6 protruding outward.
미설명 부호 15, 15'는 부시다. 상기의 구성에 따른 동작을 설명하면 다음과 같다. 먼저, 사용자의 외부 조작으로 구동기어(12)와 믹싱기어(11)가 회전하면 제3도와 같이 슬리브(6)과 믹싱블래드(3)도 같이 회전하며 현상기 몸체(1)내의 토너가 자력의 영향으로 슬리브(6)에 달라 붙어 드럼(7)표면에 현상된다.Reference numerals 15 and 15 'are bushes. The operation according to the above configuration is as follows. First, when the driving gear 12 and the mixing gear 11 are rotated by the user's external manipulation, the sleeve 6 and the mixing blade 3 also rotate together as shown in FIG. 3, and the toner in the developer body 1 Under the influence, it sticks to the sleeve 6 and is developed on the surface of the drum 7.
상기와 같은 동작이 반복되어 토너가 어느 정도 소모되면 경사진 진동판(4)상단에 있는 토너가 흘러 내리지 못하고 그대로 남게되는데, 이때는 슬리브(6)내에 설치된 자석(5)의 영향으로 자성체인 진동판(4)이 스크류(14)로 체결된 상단을 중심으로 점선과 같이 회동한다.If the above operation is repeated and the toner is consumed to some extent, the toner on the inclined diaphragm 4 does not flow down and remains as it is. In this case, the magnetic diaphragm 4 is affected by the magnet 5 installed in the sleeve 6. ) Is rotated as a dotted line around the upper end fastened with the screw (14).
이때에는 슬리브(6)이 회전하면서 전극이 계속 바뀌게 되어 진동판(4)이 점선과 같은 동작을 계속 반복함으로서 토너가 아래로 흘러내리게 된다. 이와 같이 본 고안은 간단한 구성으로 토너 보급을 원활히 하여 품질향상에 기여 할수 있고, 진동판(4)이 슬리브(6)과 직접 접촉을 하지 않은 상태에서 자력에 의한 상, 하 운동을 함으로서 진동이나 소음 발생을 방지할 수 있는 것이다.At this time, as the sleeve 6 rotates, the electrode continuously changes, and the diaphragm 4 repeatedly repeats an operation such as a dotted line, causing the toner to flow down. As such, the present invention can contribute to the improvement of quality by smoothly supplying the toner with a simple configuration, and the vibration plate 4 generates vibration and noise by moving up and down by magnetic force without directly contacting the sleeve 6. This can be prevented.
