摘要
An image scanning apparatus according to the present invention is directed to a copying apparatus capable of continuously copying a plurality of sheets on a record medium, including a platen on which an original is placed, an illuminating device for illuminating the original, an image forming device receiving reflected light from the original for reproducing an image of the original on the record medium, a scanning device moving in a first direction to scan the original and moving in a second direction to return to a predetermined position, a magnification specifying device for specifying a copying magnification at which the original is reproduced on the record medium, a projecting device for variable-scale magnifying the image of the original being scanned at the specified magnification to introduce the magnified image into the image forming device, a driving device for driving the scanning device and driving the scanning device to move in the first direction at different speed corresponding to the specified magnification, a first control device for making the illuminating device light on while moving in the second direction and light off when the scanning of the original is terminated, and a second control device for determining based on the specified coyping magnification a timing for the first control device to make the illuminating device light on.
