Are located in the lateral grooves 26a, respectively. When the handle 25 is pushed down from this state, the photoconductor cartridge 9
Rotates about the projection 24 as a fulcrum against the spring 29, so that the drum shaft 10a moves to the vertical groove 2 as shown in FIG. 4 (b).
The lower end of 6b is moved to the connecting portion with the lateral groove 26a, and while keeping the state as it is, the photosensitive member cartridge 9 is pulled forward by the handle 29 and pulled out from the guide groove 26 of the upper housing 2. At this time, the urging force of the spring 29 that presses the exposure head 16 against the photoconductor cartridge 9 causes the drum shaft 10a to be pulled out from the lateral groove 26a with respect to the photoconductor cartridge 9 by the action of the cam portion 30 of the frame 22. Therefore, the work of removing the photoconductor cartridge 9 is facilitated.

の位置関係におかれている。When the drum shaft 10a eventually reaches the connecting portion of the horizontal groove 26a and the vertical groove 26b, as shown in FIG. 4B, the photosensitive member cartridge 9 rotates by its own weight with the protrusion 24 as a fulcrum. The drum shaft 10a is moved to the lower end of the vertical groove 26b by the movement. At this time, spring 2
The biasing force of 9 acts to push the drum shaft 10a toward the lower end of the vertical groove 26b with respect to the photoconductor cartridge 9 by the action of the cam portion 30, and finally holds the temporarily held state shown in FIG. 4C. Contribute to. In this temporary carrying state, the photoconductor cartridge 9 and the exposure head 16 are already in a predetermined positional relationship, that is, the photoconductor drum 10 and the LCD head portion 27 are in a predetermined positional relationship.
