<p><P>PROBLEM TO BE SOLVED: To provide an image reading apparatus of high image quality by suppressing the maximum consumption current of the image reading apparatus. <P>SOLUTION: The image reading apparatus (100) includes a plurality of sensor IC chips (122a-122l) arranged in a columnar formation, and they are sectioned into two or more blocks. Common clock pulse signals (CLK) are inputted to the respective sensor IC chips (122a-122l) and analog output signals (A1-A6) are individually outputted for the respective blocks. Start pulse signals (SP1-SP6) are individually inputted for the respective blocks, and the start pulse signals (SP1-SP6) are inputted in common to the sensor IC chips within the same block. Contrary to the start pulse signal (SP1), the start pulse signal (SP2) is delayed and inputted. The delayed start pulse signals among the respective start pulse signals (SP2-SP6) are inputted under the similar condition thereafter. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
