본 고안은 형상장치의 토너 공급에 관한 것으로, 특히 토너상자속의 토너를 토너 호퍼를 이용하여 공급하는 구조에 적당하면서 토너함의 토너 흐름을 원활히 하여 토너 상자 공간을 최대한 증가시킬 수 있도록한 공급장치에 관한 것이다.The present invention relates to supplying toner of a shape device, and more particularly, to a supply device for supplying toner in a toner box by using a toner hopper, and to supply the toner box with a smooth flow of toner in the toner box. will be.

종래의 현상장치는 토너를 공급하기 위한 토너실과 공급된 토너를 배출시키는 현상실로 구성되어 주입시기에 따라서 분말상태의 토너를 투입구에 공급하게 되었던 것으로, 이들 종래의 구성예를 보인 제1도를 설명하면, α°만큼 기울어진 면을 가진 토너실(8)이 있고, 그 하단에서 감광드럼과 일정한 간격(Gap)을 유지하면서 회전가능한 현상로울러(20가 현상실(2a)에 설치되면서 교반과 청소 및 제거기능을 위하여 교반날개(10), 손짙날개(3), 토너 제거판(4)이 설치된 구조로서 토너실(8)과 현상실(2a)을 연통시켜 주입된 분말상의 토너(9)가 토너실(8)의 호퍼(5)에 의해 현상실(2a)로 공급되고 현상실(2a)에서는 교반날개(10)에 의해 잘 섞어 현상로울러(2)를 통해 감광드럼(1)의 표면으로 공급하였던 것이다.The conventional developing apparatus is composed of a toner chamber for supplying toner and a developing chamber for discharging the supplied toner to supply powder toner to the inlet according to the injection timing. On the bottom, there is a toner chamber 8 having a surface inclined by α °, and at the bottom thereof, a rotatable developing roller 20 is installed in the developing chamber 2a while maintaining a constant gap with the photosensitive drum. And a powdered toner 9 injected by communicating the toner chamber 8 and the developing chamber 2a with a structure in which a stirring blade 10, a hand blade 3, and a toner removing plate 4 are installed for a removing function. It is supplied to the developing chamber 2a by the hopper 5 of the toner chamber 8 and mixed well by the stirring blade 10 in the developing chamber 2a through the developing roller 2 to the surface of the photosensitive drum 1. It was supplied.

그러나 현상장치 내에 토너가 부족하면 토너실(8)의 호퍼(6)를 회전시켜 현상실(2a)로 공급하였지만 토너실(8)의 α각도만큼 기울어진 면을 따라서 공급되는 토너(9)와 경사면 사이에는 마찰력이 발생하여서 "A"부처럼 일부 토너가 남아 있게 되는 결점이 있었다.However, when the toner is insufficient in the developing apparatus, the hopper 6 of the toner chamber 8 is rotated and supplied to the developing chamber 2a, but the toner 9 supplied along the inclined surface by the α angle of the toner chamber 8 and There was a defect that frictional force was generated between the inclined surfaces so that some toner remained like the "A" part.

이러한 원인을 살피면 토너실(8) 경사면의 기울기 α가 어느정도 이하로 되면 흘러내리지 못하는 것으로 토너(9)는 있으나 공급이 안되어 마치 토너가 없는 상태인 것 같은 상태로 파악되어 다시금 주입 해주었다.In view of these causes, when the inclination α of the inclined surface of the toner chamber 8 becomes below a certain level, the toner 9 cannot be flowed down.

이때 공급되지못한 A부분이 차지하고 있는 면적이 있어서 유효체적이 감소하는 결점이 있었다.At this time, there was a defect that the effective volume is reduced because of the area occupied by the unsupply part A.

상기의 결점을 제거하려면 α각을 증가시켜야 했으나 이때에는 토너함의 체적이 감소하는 문제점이 있었다.In order to eliminate the above defect, it was necessary to increase the α angle, but there was a problem in that the volume of the toner box was reduced.

따라서 상기의 문제점들을 모두 제거하려면 결국 현상기의 크기가 대형으로 되어야 하는 문제점이 있었던 것이다. 또한 호퍼 사이에 토너가 종종 끼어서 호퍼와 토너사이의 틈새가 토너에 의해 막혀 버려서 토너 공급이 불가능한 단점이 있었다.Therefore, in order to eliminate all the above problems, there was a problem that the size of the developing device had to be large. In addition, the toner is often sandwiched between the hopper and the gap between the hopper and the toner is clogged by the toner, which makes it impossible to supply the toner.

이러한 여러가지 문제점들을 해결하기 위한 본 고안은 토너실의 기울기(α°)를 줄여 유효체적을 증가시켜 토너가 내려가지 않는 문제점을 해결하고 투입구 상부에 진동판을 설치하여 하단에서 압축스프링으로 탄지하고, 진동판 사이에 설치하는 호퍼의 바깥둘레에 적어도 2개 이상의 돌기를 형성하여 호퍼와 토너 사이가 막히지 않도록 하며, 토너의 공급기능을 수월하게 하고, 특히 현상기의 크기를 변형시키지 않는 상태에서도 유효체적이 넓고 토너의 공급이 원활하게 한 것이다.The present invention to solve the various problems such as to reduce the inclination (α °) of the toner chamber to increase the effective volume to solve the problem that the toner does not fall, install the diaphragm in the upper part of the inlet to press the compression spring at the bottom, the diaphragm At least two projections are formed on the outer circumference of the hopper installed between them to prevent the hopper and the toner from clogging, to facilitate the supply of the toner, and in particular, the effective volume is wide even when the size of the developer is not changed. Supply would be smooth.

이를 첨부도면에 따라 상세하게 설명하면 다음과 같다.This will be described in detail according to the accompanying drawings.

제2도는 본 고안의 설치상태 단면도인 것으로, 감광로울러(1)와 어느정도 간격을 가지며 회전 가능하게 설치하는 현상로울러(2)를 현상함(6)의 현상실(2a)에 설치하고, 현상실(2a)과 연통되게 상으로 형성한 토너실(8)의 기울기(α°)는 작게하여 내용면적이 넓은 토너실(8)을 형성하며, 토너실(8)의 투입구(9) 하단에 돌기(5a)가 형성된 호퍼(5)를 설치하고 상단에는 진동판(11)(11')을 설치하는 구성으로 토너공급장치를 형성하고 토너공급장치의 기능을 원활히 발휘하기 위해 압축스프링(15)을 진동판(11)(11')의 하단에 삽지하며, 스토퍼(17)를 그 상측에 삽지한다.2 is a cross-sectional view of the installation state of the present invention, in which the developing roller 2 is installed in the developing chamber 2a of the developing chamber 6 so as to be rotatably installed at a certain distance from the photosensitive roller 1. The inclination α of the toner chamber 8 formed in communication with (2a) is small to form a toner chamber 8 having a large inner surface area, and a projection at the bottom of the inlet 9 of the toner chamber 8. To install the hopper (5a) formed and the diaphragm 11 (11 ') at the top to form a toner supply device and to facilitate the function of the toner supply device, the compression spring 15 to the diaphragm (11) (11 ') is inserted in the lower end, and the stopper 17 is inserted in the upper side.

제3도는 본 고안의 요부 발췌 사시도인 것으로, 진동판(11)(11')은 선단이 구부러진 평판 형태에 후단양측을 구부려서 힌지편(13)에 축(13a)을 형성하고 선단의 만국진 부분과 탄력있게 면 접촉하는 호퍼(5)의 양측에 각각 돌기(5a)를 형성하여서 된 것이다.Figure 3 is a perspective view of the main portion of the present invention, the diaphragm 11 (11 ') is bent the rear end side in the form of a flat bent end to form a shaft (13a) on the hinge piece 13, The protrusions 5a are formed on both sides of the hopper 5 which is elastically face-contacted.

이러한 구성으로 이루어진 본 고안의 작용효과를 제4도에 의해 설명하면, 본 고안의 토너실(8)은 기울기(α°)를 작게한 관계로 호퍼(5)와 토너(T) 사이의 간격이 넓어질 우려가 있으나 이는 상측의 축(13a)이 브라켓트(8a)에 설치되며 하단이 압축 스프링(15)에 의해 돌려지는 설치 구성에 의해 제4(a)도와 같이 진동판(11)(11')의 선단과 호퍼(5)의 면과 접촉되어 토너의 주입을 막는 닫힘 상태로 접촉하고 있다가 전기적인 신호에 의해 호퍼(5)가 반시계 방향으로 회동하면 제4(b)도와 같이 돌기(5a)가 진동판(11)(11')을 회전력으로 눌러 호퍼(5)와 진동판(11)(11') 사이에 틈새를 형성하는 열림상태가 된다.Referring to FIG. 4, the toner chamber 8 of the present invention has a small inclination α °, and thus the distance between the hopper 5 and the toner T is reduced. It may be widened, but this is due to the installation configuration in which the upper shaft 13a is installed on the bracket 8a and the lower end is rotated by the compression spring 15, as shown in FIG. 4 (a), and the diaphragm 11, 11 '. When the hopper 5 rotates in a counterclockwise direction by an electric signal after contact with the tip of the hopper 5 in a closed state to contact the surface of the hopper 5 and prevent the injection of toner, the projection 5a as shown in FIG. ) Presses the diaphragm 11 (11 ') with the rotational force, and becomes an open state which forms a gap between the hopper 5 and the diaphragm 11 (11').

이 상태에서 생기는 진동간격 즉, 틈새(E)로 토너(T)는 배출되며, 호퍼(5)의 계속 회전으로 상기의 열림상태는 닫히게 되어 다시 제4(a)도와 같은 상태로 된다. 따라서 상기의 구동이 반복될때 토너(T)는 엉켜짐이나 마찰력에 의한 뭉침 현상이 제거되고 또한 닫힐때 스프링에 의한 충격으로 토너(T)는 호퍼(5)나 진동판면에 묻지 않게되어 토너의 공급이 매우 원활하다.The toner T is discharged at the vibration interval generated in this state, that is, the gap E, and the open state is closed by the continuous rotation of the hopper 5, and the state is again as shown in the fourth (a) degree. Therefore, when the above driving is repeated, the toner T is eliminated from being entangled or agglomerated due to the frictional force, and when the toner T is closed, the toner T does not adhere to the hopper 5 or the diaphragm surface due to the impact of the spring. This is very smooth.

이러한 작용에 의해 얻어지는 효과는 기존의 토너실의 기울기를 적게하면서 진동판을 부착함에 따라 토너가 흘러내리지 않는 결점과 호퍼에 끼어 틈새가 막히는 결점이 상술한 바와 같은 기울기 줄임과 진동판의 충격으로 제거되어 기능의 원활함은 물론 토너의 수용능력이 동일조건 하에서 커지는 효과가 있는 것이다.The effect obtained by this action is eliminated by the reduction of the inclination and the impact of the diaphragm as described above, in which the defect of the toner does not flow as the diaphragm is attached while the inclination of the existing toner chamber is reduced and the gap is blocked by the hopper as described above. Of course, the toner's capacity is increased under the same conditions.
