Abstract
An image scanning device includes a CCD pair provided with two rows of photodiode arrays for scanning an image on a paper, a motor drive circuit for causing the CCD pair to sub-scan the image on the paper, and an adder for superimposedly combining two outputs of the CCD pair with a predetermined time lag therebetween. A control unit controls the adder to add the two outputs of the CCD pair without the time lag when received an instruction of a low resolution that corresponds to ½ of a high resolution by a resolution switch and thereby doubles a speed of the sub-scan by the motor drive circuit.
