Abstract
An image reading apparatus includes two color line cameras and one monochrome line camera and captures a linear imaging area on printing paper. The imaging area is irradiated with illumination light by a line illumination part. When inspecting a printed image, a color image captured with the color line cameras and an original image are compared. An information element image such as a bar code is clipped from a monochrome image captured with the monochrome line camera, and target information indicated by an information element(s) is acquired. In the image reading apparatus, since the color image and the monochrome image are acquired from the same imaging area, it is possible to realize downsizing of the line illumination part and downsizing of the image reading apparatus.
