Zusammenfassung:PROBLEM TO BE SOLVED: To make a reader small in size as a whole, low in cost and high in image reading speed by reading an image even in an acceleration/deceleration state. SOLUTION: The acceleration/deceleration of a motor 29 is controlled by a speed control pattern in a trapezoidal shape stored in a memory 27, and a CPU 26 allows a clock revision circuit 30 to revise a clock period in a main scanning in response to a drive speed of the motor even in a sate of acceleration/deceleration of the motor. Thus, a CCD or a CIS reads an image even in the state of acceleration/deceleration.
