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 is provided between lamps and eliminates electric potential in a specific area on the surface of a photosensitive drum by blinking control of the static elimination lamp, which enables copying in the center reference copying machine. An integer number of static elimination lamps corresponding to the minimum size copy paper width is fixedly provided as the upper limit of the number of static elimination lamps, and the number of fixed static elimination lamps is subtracted from the required total number of static elimination lamps to divide it into two, and at least one of each is divided into two. The arrangement pitch of the partition plate is such that the first and second static elimination lamp groups including the static elimination lamps are placed on both sides of the fixed static elimination lamp in the direction of the axis of the drum, and the light emitting areas can partially overlap. A specific area neutralization mechanism for a center reference copying machine, characterized in that the specific area neutralization mechanism is provided so as to be movable in the drum axis direction by at least one pitch.
