<p>A delay circuit is provided to a connection line for connecting an A/D converter to an image data creating circuit, and consequently the output timings of the digital electric signals outputted from the A/D converters are different. As a result no digital electric signals are not outputted simultaneously from adjacent output terminals of the A/D converter. Therefore no digital electric signals outputted from the A/D converter go from low to high or from high to low level simultaneously, thereby reducing the amplification of the EMI. Therefore no noise is contained in the image data created by the image data creating circuit and the quality of image read by an image reader is improved.</p> |
