Abstract
In an image signal processing portion, the size of an original papersheet is detected, and image data is provided with respect to a memory unit. The size of a copy papersheet is detected using a detecting sensor, not shown. Data of an original image is read out by a CCD to be stored in an image memory. When printing is carried out based on the image data, the feeding directions and the sizes of the original papersheet and the copy papersheet are taken into consideration. When the feeding directions of the original and the copy papersheet are the same, only a variable-scale magnification processing portion is activated to carry out only a variable-scale magnification processing. When the feeding directions of the original papersheet and the copy papersheet are different, a rotation and a variable-scale magnification of an image signal are carried out by a rotation processing portion and the variable-scale magnification processing portion. As a result, irrespective of the direction and the size of the original, the image is automatically copied onto the copy papersheet.
