【発明の詳細な説明】
複写機のドラムの周面に付着したトナーを掻き
落とすためブラシをその周面に接して配置する
が、このブラシは数本を組立体とし１つの筐体に
収納している。ブラシ面とドラム周面との間隙は
微細な調節を要するがブラシは頻繁に取り替える
ものであり、従つてクリーニングブラシ組立体は
着脱が容易なばかりでなくその取付時の位置を微
細な調節が容易に出来なければならない。[Detailed Description of the Invention] A brush is placed in contact with the peripheral surface of the drum of a copying machine in order to scrape off toner adhering to the peripheral surface of the drum, and several brushes are assembled and housed in one housing. ing. The gap between the brush surface and the drum circumferential surface requires fine adjustment, but brushes are replaced frequently, so the cleaning brush assembly is not only easy to attach and detach, but also easy to finely adjust its mounting position. must be able to
そこで本発明に於いてはブラシ７の組立体の筐
体の両側面夫々の上・下部に２本のピン１，２を
立設し先づ上方のピン１はフレームよりドラム付
近に向けて固定されている架台３に上から引掛け
る様にした。架台３は上方が自由空間とし、且つ
架台の１部にピン１がゆるく落ち込む半円形の凹
所をつけていく。この様にすることに依り上方の
ピンは先づ非常に容易にフレーム４に取付け得る
と同時にブラシ組立体５とドラム６との間隙は一
応粗調整ながら達成出来る。 Therefore, in the present invention, two pins 1 and 2 are provided upright at the upper and lower parts of both sides of the housing of the brush 7 assembly, and the upper pin 1 is fixed toward the drum nearer than the frame. I made it so that it could be hung from above on the pedestal 3. The pedestal 3 has a free space above, and a semicircular recess into which the pin 1 falls loosely is provided in a part of the pedestal. By doing so, the upper pin can be first attached to the frame 4 very easily, and at the same time, the gap between the brush assembly 5 and the drum 6 can be achieved with some rough adjustment.

対して移動出来る様にする。 Fine adjustment in the present invention is achieved by adjusting the lower pin 2 back and forth relative to the drum 6. For this purpose, a two-pronged member 9 is prepared instead of a pedestal for receiving the upper pin 1, and the shaft 8 is attached to the frame using the approximately central part of the two-pronged member 9.
to pivot. The front end of the bifurcated member 9 is bifurcated, the front end of this slot is open, and the width is such that the pin 2 can be loosely fitted into the slot 10.
Let it loosely fit. Now, a slot 11 is also formed at the rear end of the two-pronged member 9, which is formed into an annular shape, and an eccentric cam 12 pivotally connected to the frame 4 is inserted into the inner surface of the slot 11, and by rotating this, the front end of the two-pronged member can be moved up and down. to allow the pin 2 in the forked slot to move relative to the drum.
尚この調整で問題となるのは保守管理面が片側
にしかない事であり、複写機の奥側にあるブラシ
組立体側面にはアクセス出来ない事である。そこ

ヤフト１３を貫通しておき、これをレバ１４で回
動する事に依りこの目的を達成している。 The problem with this adjustment is that the maintenance surface is only on one side, and the side of the brush assembly located at the back of the copier cannot be accessed. Therefore, this purpose is achieved by passing the shaft 13 through the eccentric cam 12' fitted into the slot 11' of the two-pronged member on the back side of the slot 11, and rotating it with the lever 14. are doing.
尚微調整完了後はロツクねじ１５で固定する。 After completing the fine adjustment, fix it with the lock screw 15.
