Abstract
An image reader for reading images on a surface of a medium, having a feeding device for feeding the medium, carriage movable in a direction perpendicular to the direction of feed of the medium, a driving device for moving the carriage, and a reading head mounted on the carriage for reading the images on the medium surface. The image reader comprises an area setter for setting a reading area on the medium surface within which the images are read by the reading head. The reading area is set while the reading head is moved relative to the medium by the feeding and driving devices. The image reader further comprises a controller for controlling the feeding and driving devices and the reading head, to cause the reading head to read the images within the set reading area while the reading area is scanned by the reading head.
