し得るのでひろく用いられている。In a known electrostatic copying machine that transfers an image formed by toner on the surface of a moving photoreceptor to transfer paper, residual toner remaining on the photoreceptor after transfer is removed so that it does not interfere with the next copying operation. It is well known that cleaning equipment is not provided for this purpose because it is necessary to remove the dust sufficiently. There have been many proposals for cleaning devices, but one that uses a cleaning blade and scooping sheet, as shown in Figure 1, is simple and effective in removing residual toner. It is widely used because it provides

１を具備している。The above cleaning device, as schematically shown in FIG.
Cleaning blades 6 are arranged close to the photoreceptor traveling in the direction of the arrow and alternately layered on the photoreceptor, and a scooping sheet 4 is arranged upstream of the cleaning blade 6 in the direction of travel of the photoreceptor.

がある。また廃トナーを貯溜する容器は廃トナーが充満
すれば機外にとり出して容器でとあるいはトナーを廃棄
してクリーニング装置に装填する必要がある。The scooping sheet is made of a relatively soft material such as a thin film of synthetic street grease, and is placed in close contact with the photoreceptor in the area upstream of the cleaning blade where residual toner exists, so toner does not adhere to it. Because it solidifies, local deformation and wear occur due to long-term use, resulting in deterioration of mNQ, it is necessary to clean or replace it as necessary. Furthermore, when the container for storing waste toner is full of waste toner, it is necessary to take it out of the machine and either use the container or discard the toner and load it into the cleaning device.

かった。The waste toner container disposed inside the cleaning device has an opening for storing the toner scraped by the blade through a scooping sheet, so it can be used during cleaning, loading, etc. as described above. Toner leaks from this opening,
The inconvenience of scattering and staining the inside and outside of the copying machine could not be avoided.

ある。The present invention has been made in view of the drawbacks of the known cleaning devices as described above, and the present invention combines a waste toner container and a scooping member including a scooping sheet, and when the waste toner container is taken out from the cleaning device. The purpose of the present invention is to improve the conversion efficiency of the container by configuring the scooping member to close the opening of the waste toner container to prevent the above-mentioned defects as much as possible. It is something.
以下添付の図面によって本発明の好［相］な実施例につ
いて説明する。Preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

側の端縁にはすくい部材４が回動自在に配設しである。FIG. 1 is a side sectional view showing the structure of a cleaning device according to the present invention, in which a cleaning device designated by reference numeral 10 is disposed adjacent to a cylindrical photoreceptor 1 rotating in the direction of the arrow in the figure. The cleaning device 10 includes a casing 2, and a cleaning blade 6 is attached to the upper side of the casing 2. The free end of the cleaning blade is always pressed against the surface of the photoconductor to scrape off residual toner on the surface. shall be dismissed. Inside the casing 2 is a toner container 5.
is stored in a removable manner. An opening 51 is formed on the top surface of the container 50, and a scooping member 4 is rotatably disposed on the edge of the surface of the container 50 on the side closer to the photoreceptor 1.
すくい部材４は図から明らかなように廃トナー容缶端縁
に沿って該容器侵手方向（紙面に垂直な方向）にのびて
いて断面はぼくの字状に形成されており、その一方の辺
には前述のような薄膜状のすくいシート４１が固着され

してあり、この部分には立下り都４６がもうけてあり、
該立下り部４６と容器５の側壁にもうけたピン５４の間
にはコイルばね６が引張り状に懸架しである。As is clear from the figure, the scooping member 4 extends along the edge of the waste toner can in the direction of the container (perpendicular to the plane of the paper), and has a cross section shaped like a Japanese character. A thin film-like scooping sheet 41 as described above is fixed to one side, and the other side has falling portions 42 at both ends (only one of them is shown in the figure). Each lowering portion 42 is pivotally connected to a proper position on the side wall of the waste toner container 5 by means of a bottle P, and the scooping member 4 is rotatable about the pin P. A protrusion 44 is further formed on at least one end of the other side of the scooping member 4, and a falling capital 46 is provided in this portion.
A coil spring 6 is suspended in tension between the falling portion 46 and a pin 54 provided on the side wall of the container 5.
第１図から判るように、回動自在に容器５に取り付けら

沿って落下して開口５１を経て容器５内に貯溜されるこ
とになる。As can be seen from FIG. 1, the scooping member 4, which is rotatably attached to the container 5, has a tendency to rotate clockwise in the figure due to the action of the coil spring 6.
It is assumed that the free end of the scooping sheet 41 is maintained in this position by the stopper action of the upper right end portion 56 shown in the figure, and at this time, the free end of the scooping sheet 41 is in contact with the surface of the photoreceptor in a desired state. Therefore, in this state, the residual toner on the surface of the photoconductor is at the position of the scoop sheet 41 as the photoconductor travels, and then passes through this and is scraped off from the photoconductor at the position of the cleaning blade 6, and this toner is removed from the surface of the scoop sheet. It falls along the path, passes through the opening 51, and is stored in the container 5.

に々る。When the container 5 is filled with waste toner or when the scoop sheet 41 needs to be cleaned or replaced and these parts are taken out of the copying surface, the copying machine side lid and, if necessary, the side wall of the casing 2 are opened. After exposing the side of the container 5, the protrusion 4 formed on the scoop member 4
4, and remove the rake member 4 against the action of the coil spring.
is rotated counterclockwise around the bottle P, and brought to the position of the wholesale line in Figure 1. As is clear from the figure,
Since stoppers 52 are formed at both ends of the opening 51 of the container 5 (only one of them is shown in the figure), the one side of the scoop member 4 comes into contact with the stopper and the member stops. , is stably maintained in this position by a snap action by the coil spring at position 61.
このとき、第１図に示すように、すくいシート４１をふ
くめですくい部材４が容器５の開口５１を閉塞するよう
に構成しである。したがってこの状態で答益５を、すく
い部材４によって開口５１を閉滉したまま複写機外に引
き出すことが可能となる。At this time, as shown in FIG. 1, the scooping member 4 including the scooping sheet 41 is configured to close the opening 51 of the container 5. Therefore, in this state, it is possible to draw out the paper 5 out of the copying machine with the scoop member 4 keeping the opening 51 closed.
この発明はおおむね以上のように構成されているから、
廃トナーの充満した容器５を密閉状態でクリーニング装
置に対して着脱できるので、装脱時に多少手荒く取り扱
っても各器内のトナーが肩出、飛散するおそれかないた
めに作業が容易かつ能率的に遂行できる。Since this invention is generally configured as described above,
Since the container 5 filled with waste toner can be attached to and removed from the cleaning device in a sealed state, there is no risk of the toner in each container spilling out or scattering even if the container is handled somewhat roughly during loading and unloading, making the work easier and more efficient. Can be carried out.

トナーが動き出して周囲を汚損するおそれもない。Furthermore, since the container and the scooping member are integrated, and the scooping sheet surface that guides the waste toner in the operating position is located on the inner side 1 when the opening 51 is closed, the two are separate bodies. There is no fear that the waste toner remaining on the surface of the scoop sheet inside the cleaning device will move and stain the surrounding area due to vibrations, shocks, etc. when loading and unloading the container, unlike the conventional cleaning device.
また容器とすくいシートとを一体として交換できるから
交換の作業性も向上する。さらにまた図示の構成からも
明らかなように公知のこの棹のクリーニング装置にコイ
ルばねを付加し、若干の設計変更を加えるだけで実施す

いものである。Furthermore, since the container and the scooping sheet can be replaced as a unit, the work efficiency of replacement is improved. Furthermore, as is clear from the configuration shown, it can be implemented by adding a coil spring to this well-known neck cleaning device and making slight design changes, making it low cost and extremely practical. be.
