る。This paper feeding device, for example, stacks a large number of sheets in a paper feeding box, places a paper feeding roller in opposition to the top surface of the topmost sheet, and rotates this paper feeding roller.
It is well known that a paper feeding system in which the topmost sheet is fed is already in general use.

よって送り出す方式にとっては給紙ローラーの周表面の
平滑度や摩擦係数やあるいは塵埃の付着状態等の条件が
シートを確実に送り出す上で犬きく影響する。In the above-mentioned paper feeding method, the fed sheet is fed out by the friction between the paper feeding roller and the sheet that is in contact with it. Conditions such as the smoothness of the circumferential surface, the coefficient of friction, and the state of adhesion of dust greatly influence the reliable feeding of the sheet.
上記の平滑度や摩擦係数等の点は設計上あるいは工作上
から適宜に考慮されている。The above-mentioned points such as smoothness and friction coefficient are appropriately taken into consideration from the design or manufacturing standpoint.

ため、給紙ローラーの摩耗が早く々り給紙ローラーの寿
命が短くなる等の欠点があった。Conventionally, to remove dust and paper powder, there were cleaning devices equipped with a cleaning pel that was in contact with the circumferential surface of the paper feed roller or a belt with a brush-like surface, but these devices were large and complicated. Since the feed roller is in contact with the paper feed roller, the paper feed roller wears out quickly, which shortens the life of the paper feed roller.

部材のクリーニング装置を提供することにある。The present invention has been made in view of the circumstances described in -F, and its purpose is to provide a rotating paper feeding member that can maintain the surface of the rotating paper feeding member in a clean state at all times and smooth the paper feeding action. The purpose of this invention is to provide a cleaning device for cleaning.

ある。Hereinafter, the present invention will be explained with reference to all the drawings. FIG. 1 shows an electrostatic copying machine. In FIG. 1, 1 is a photosensitive drum, 2 is a charging device, 3 is a document table, 4 is a current device, 5 is a paper feed stand, 6 is a paper feed roller as the rotating paper feed member 20, and 7 is a paper feed device. , 8
1 is a fixing roller, 9 is a discharge path, and 10 is a paper discharge tray.
給紙ローラー６は軸１２に設けた支持腕１１に支持され

枚の用紙であるシート１８の轍上位のものの先側上面に
所定の圧力で載っており、図示しない駆動機構により適
時に矢印方向に回転し、シート１８を１枚毎に矢印方向
に送り出す。The paper feed roller 6 is supported by a support arm 11 provided on a shaft 12, and the paper feed roller 6 is mounted on the upper surface of the top surface of the top of the rut of a plurality of sheets 18 placed on the paper feed table 5. The sheet 18 is placed on the sheet 18 under a predetermined pressure, and is rotated in the direction of the arrow at appropriate times by a drive mechanism (not shown) to feed out the sheets 18 one by one in the direction of the arrow.
給紙ローラー６の上位にはクリーニング部材１３が給紙
ローラー６とは非接触で設けである。A cleaning member 13 is provided above the paper feed roller 6 without contacting the paper feed roller 6.
クリーニング部Ｉ３はゴム、布、金属等からなる板状の
ものであり、このクリーニング部材１３はクリーニング
取付部材取付カバー１４に貼りつけである。The cleaning part I3 is a plate-shaped member made of rubber, cloth, metal, etc., and the cleaning member 13 is attached to a cleaning mounting member mounting cover 14.
しかして、給紙ローラー６が回転し、給紙台５上のシー
ト１８が送り出されると、シート１８上の塵埃や紙粉等
は給紙ローラー６の周面につきはじめる。When the paper feed roller 6 rotates and the sheet 18 on the paper feed table 5 is sent out, dust, paper powder, etc. on the sheet 18 begin to adhere to the circumferential surface of the paper feed roller 6.
そして、この塵埃や紙粉等はクリーニング部材１３に静
電気的に移動する。このため給紙ローラー６の周面はき
れいに清掃され、給紙ローラー６の表面の摩擦係数を所
定の値に維持し、紙送りが問題なく確実にできる。Then, this dust, paper powder, etc. are electrostatically moved to the cleaning member 13. Therefore, the circumferential surface of the paper feed roller 6 is thoroughly cleaned, the friction coefficient of the surface of the paper feed roller 6 is maintained at a predetermined value, and the paper can be fed reliably without any problems.
第３図に示すものは回転給紙部材２０の他の実施態様の
ものにクリーニング部材（３を設けた給紙装置である。What is shown in FIG. 3 is a paper feeding device in which a cleaning member (3) is provided in addition to another embodiment of the rotary paper feeding member 20.
