Image-forming apparatus with an area-selecting function which selects an area in a surface-up condition of an original and which forms an image on the basis of the selected area of the original placed in a surface-down condition

摘要

An image-forming apparatus for forming an image on an image- bearing member on the basis of an original image, including: a platen on which an original having an original image is placed, the platen having a reference portion; an input device for inputting coordinates representing a predetermined area of the original placed in a surface-up condition on the reference portion; and a control unit for performing coordinate transformation from the coordinates to transformed coordinates. The transformed coordinates represent the predetermined area of an original placed in a surface-down condition. The image-forming apparatus includes an image-scanning unit. The image-scanning unit has an electric component which scans an original placed in the surface-down condition on the reference portion. The image-forming apparatus further includes an image- forming unit. The image-forming unit has an electric component which forms an image on an image-bearing member on the basis of the original image which the image-scanning unit scanned, and which is limited to the predetermined area represented by the transformed coordinates.
