ABSTRACT:
In a scanning type copying machine of the present invention, a scanner scans divided regions of a document prior to real copy operation when a dividing copy mode is selected by a book copy mode selection key. Density control data in the respective divided regions are stored in memory and an exposure lamp is controlled by a MPU so that a copy of an appropriate density can be formed according to the stored density control data. Thus, without being unfavorably influenced by a difference of the densities in the divided regions of the document, copies of appropriate densities can always be obtained.
