ABSTRACT:
An image scanning apparatus is provided by (1) a platen on which an original can be placed; (2) a scanning device for scanning the original, which includes a lens for projecting the image of the original on an imaging plane; (3) an image sensor for sensing the image projected on the imaging plane which consists of a plurality of elements arranged linearly along to the imaging plane; (4) a memory device for storing data sensed by the image sensor during a scan by the scanning device; and (5) an assembly for determining the real image area on the original based on the data stored in the memory device. To the above apparatus can be added an output control device for sending digital data of a real image area. A copier according to the present invention which can copy a manuscript, comprises: (1) the above-mentioned image scanning apparatus; (2) is also provided by the above by including an image forming device and (3) a control device for allowing the image forming device to form only the image in the image area. Also, a light controller for an image reader is provided by a standard pattern plate which has a standard pattern of a prescribed density; a light source driven by an electric power source of alternating current, illuminating the standard pattern plate and an original; and can compensate the ac ripples of the image signal.
