Description of the Related Art Electronic copying machines are known whose main bodies can be divided into upper and lower halves in order to facilitate maintenance, inspection, cleaning, or repair work on the electronic copying machines. In this system, an upper frame including an exposure mechanism, a developing device, and a cleaning mechanism is rotatably connected to a lower frame including a photoreceptor and the like with one end serving as a fulcrum. When performing maintenance, inspection, or repair inside the main unit, first open the upper frame upward relative to the lower frame.
Although the photoreceptor is removed from the main body, a cleaning mechanism is provided close to the photoreceptor. Therefore, when attaching and detaching the photoreceptor, the photoreceptor comes into contact with the cleaning mechanism, which may damage the surface of the photoreceptor, and the cleaning mechanism gets in the way, making it difficult to attach and detach the photoreceptor.

ことはない。 Next, the operation of the above embodiment will be explained.
In normal use, as shown by the solid line in FIG. It is held in its normal position. In this state, when performing maintenance, inspection, cleaning, or repair inside the main body 1, first remove the photoreceptor 4.
In order to prevent interference between the cleaning mechanism 15 and the cleaning mechanism 15, it is necessary to retreat the cleaning mechanism 15 from the photoreceptor 4. Therefore, the operation pin 27 is pulled against the restoring force of the coil spring 29 and pulled out from the first engagement hole 30a.
Next, when the rotary lever 23 is rotated in the direction of the arrow, the cleaning mechanism 15 is pivoted about the pivot pin 19 as a fulcrum and is retracted from the photoreceptor 4 . After the operating pin 27 is opposed to the second engagement hole 30b, when the finger is released, the operating pin 27 is moved into the second engagement by the restoring force of the coil spring 29, as shown by the two-dot chain line in FIG. It engages with the matching hole 30b. In this state, when the upper frame 3 is rotated upward using one end thereof as a fulcrum, the main body 1 consisting of the lower frame 2 and the upper frame 3 is opened as shown in FIG. Therefore, in this state, the photoreceptor 4 can be removed from the lower frame 2, and at this time the cleaning mechanism 1
5 is retracted from the photoreceptor 4, so that interference with the photoreceptor 4 can be prevented and it does not get in the way.
なお、この場合、清掃機構１５は上向き状態の
まま上部フレーム３とともに上方へ退避するた
め、清掃機構１５からトナーが落下することはな
い。 In this case, since the cleaning mechanism 15 is retracted upward together with the upper frame 3 while facing upward, toner does not fall from the cleaning mechanism 15.
また、上述のように感光体４から清掃機構１５
を退避できることによつて感光体４と清掃機構１

By being able to evacuate the photoconductor 4 and the cleaning mechanism 1
If a paper jam occurs between the two, it can be easily removed. Furthermore, if a paper jam occurs around the photoreceptor 4 other than the cleaning mechanism 15, the cleaning mechanism 15
It can be easily removed by rotating the upper frame 3 upward without retracting it.

体４を取り外して傷を付けることはない。 FIG. 6 shows another embodiment of this invention,
A lock lever 31 is provided at the free end of the rotating lever 23. And this lock lever 31
By engaging with the attachment/detachment mechanism of the photoreceptor 4, for example, the engaging claw 33 of the attachment knob 32, the attachment knob 32 becomes unable to rotate in the direction of arrow a, that is, in the loosening direction of the attachment knob 32. Therefore, when removing the photoreceptor 4, it is necessary to retract the cleaning mechanism 15 from the photoreceptor 4 using the rotating lever 23 and release the lock lever 31 from the mounting knob 32, which may cause the photoreceptor 4 to be removed inadvertently. It will not cause any damage when removed.
この発明は以上説明したように、感光体の表面
に残留するトナーを除去する清掃機構を、退避機
構によつて必要に応じて感光体から退避できるよ
うにしたから、保守点検、修理等の際に感光体を
損傷させることが無く、その作業の容易化を図る
ことができる。 As explained above, in this invention, the cleaning mechanism for removing toner remaining on the surface of the photoreceptor can be evacuated from the photoreceptor as necessary by the evacuation mechanism, so that it can be removed during maintenance, inspection, repair, etc. The photoreceptor is not damaged during operation, and the work can be facilitated.
また、退避機構は、清掃機構の開口部が上方に
向くように感光体から退避させるため、多少振動
等を与えてもトナーが開口部から零れ落ちること
が無い。 Further, since the retraction mechanism retracts the cleaning mechanism from the photoreceptor so that its opening faces upward, toner does not fall out from the opening even if some vibration or the like is applied.
また、退避機構は、上記清掃機構を本体に対し
て一端を支点として回動自在な回動レバーによつ

単であるといつた効果を奏する。 Further, the evacuation mechanism supports the cleaning mechanism by a rotary lever that can freely rotate with one end as a fulcrum relative to the main body, and the rotary lever can be freely engaged and detached from the main body by an engagement member. Therefore, the cleaning mechanism can be easily rotated by the rotation lever, and the operation is easy. Further, it has the advantage of being structurally simple.
