Abstract:
1. An image reading apparatus comprising: an image reading unit having a photoelectric conversion component for reading light from an image and converting the read image to an image signal; a driving motor for moving said image reading unit and the image relative to each other; a motor control unit for controlling said driving motor; an interface connecting to an external information processing device; a conversion circuit for performing analog-to-digital conversion on the image signal into image data; a memory connected to said interface for storing the image data; and a control signal receiving unit for receiving a motor control signal via said interface, wherein, when said external information processing device uses a virtual memory to store said image data obtained through the interface and when access speed of the virtual memory is lower than a reference value, said control signal receiving unit receives the motor control signal which controls said driving motor speed to be lower than the motor speed when not using said virtual memory, and wherein said motor control unit controls said driving motor according to the received motor control signal.
