ー基準複写機の特定領域除電機構。 A large number of static eliminator lamps are installed at intervals in the drum axis direction so as to be able to emit light over the entire width of the image area of the photosensitive drum, and a partition plate is provided for each static eliminator to define the light emitting area of each static eliminator lamp. A specific area static elimination mechanism for a center reference copying machine, which eliminates electric potential in a specific area on the surface of a photosensitive drum by blinking control of the required total number of static elimination lamps provided between the lamps, An integer number of first and second static elimination lamp groups obtained by dividing the lamp into two and adding at least one static elimination lamp to this,
A center reference copying machine characterized in that the light emitting areas are provided at the center reference portion so as to be movable individually in the drum axis direction by at least one pitch of the arrangement pitch of the partition plates, with the light projection areas being able to partially overlap. Specific area static elimination mechanism.
