□ □ 1” A charger, an exposure lamp, an exposure optical system, a developer, a photoreceptor rearner □, and a static eliminator i′ are arranged on the side, and the photoreceptor is rotated to pass near each of the peripheral parts mentioned above. The first steps are performed in sequence, such as stripping, exposure and development, and one copy "y crystal" is J static elimination. □ In electronic copying with a structure such as Ti, the photoreceptor and peripheral parts such as those mentioned above are Cleaning, replacement, tuning 11 m' 8
In this case, conventionally □ first pulled out the photosensitive body in the direction of the rotation axis, and then pulled out the peripheral part (or removed it). However, in conventional electronic copying machines, -C
Because each peripheral part and photoreceptor were individually attached to the main frame, each part had to be removed from the main frame one by one and taken out of the machine, making maintenance work extremely troublesome. Some copiers are available that allow maintenance work to be performed without removing peripheral parts from the machine, but in that case, the work must be done by entering the limited space after removing the photoreceptor. Therefore, it is extremely difficult to work at the back of the copier.In addition, each part is supported by its own subframe, which is expensive.
It is necessary to individually adjust the distance between each component and the photoreceptor, and furthermore, since the photoreceptor and peripheral parts are removed separately, the photoreceptor is likely to come into contact with peripheral parts and be damaged when the photoreceptor is removed.

The inserted original 20 is moved between the platen gas 13 and the platen 17 by the original feeding roller 18 and the like.
I was sent a question. At this time, the exposure lamp 12
The reflected image of the original 20 that has been subjected to P@04 is exposed to the exposure lens 14.
The C photoreceptor 7 is exposed to light and an electrostatic latent image of the original 20 is formed on the photoreceptor 71' which is charged by the charger 11.

When cleaning, replacing, or repairing peripheral parts such as the charger 11, the common frame 3 is pulled out horizontally as shown in FIG. (As shown in Figure 3, subframe 4
When rotated in the direction of arrow C, the subframe 4 moves out from above the photoconductor 7, the parts arranged above the photoconductor 7 move away from the side of the photoconductor 7, and the developing unit 9 moves away from the photoconductor 7. It is far away to the side of 7. Shii Kogak C developing device 9, static elimination lamp 1o
It becomes possible to carry out maintenance work such as cleaning on the charger 11, exposure lamp 12, etc. easily and without fear of damaging the photoreceptor 7. Furthermore, when performing maintenance on the photoreceptor 7, since the upper part of the photoreceptor 7 is open, the maintenance work can be easily performed by removing the photoreceptor 7 upward.

部品を個々に位＠調整する必要が無く便利である。Then, if the relative position of the frame 4 with respect to the photoreceptor 7 is adjusted correctly, the developing device 9, the static elimination lamp 10, and the static elimination lamp 10 supported by the subframe 4 will be removed. Since all parts such as the charger 11 take the correct position with respect to the photoreceptor 7, there is no need to adjust the position of each part individually, which is convenient.

きい。Although the above embodiment is applied to a copying machine that uses a SELFOC lens as the exposure lens 14, the present invention is of course applicable to a copying machine that uses a general convex lens as the exposure lens. In that case, instead of the SELFOC lens, the exposure lamp, and the platen glass, Surin 1~ will usually be installed. , and the maintenance work and position adjustment of the peripheral parts around the photoconductor are extremely easy, and since the photoconductor and peripheral parts are collectively supported in a common room, there is no need for separate subframes for each component. The cost reduction effect is also significant.
