Claims

[Scope of Claim for Utility Model Registration] In a mounting structure for a composite unit in which a photoconductor drum and a device that can be positioned in advance with the photoconductor drum are attached as individual units to a single housing, and this housing is mounted on a copying machine body, the above-mentioned photoconductor A support plate of a housing is provided at both ends in the axial direction of the drum to be supported with the end plate of the drum being inserted therethrough, and a positioning portion for each of the above devices is formed based on the insertion position of the end plate in this support plate. While each of the above devices is attached to the support plate via the positioning part, the drive shaft of the photoreceptor drum is positioned in advance and planted on the body side, and the end plate of the photoreceptor drum in the housing is attached to the A mounting structure for a composite unit in an electronic copying machine, characterized in that the mounting position of the photosensitive drum on the machine body side is set by inserting the photosensitive drum into a drive shaft.
