ABSTRACT:
An image reading apparatus including an image reader that outputs an image signal representing the read image to a signal line, and a controller which includes an indicating portion indicating a first reading resolution to the image reader, so that the image reader reads the image at the first reading resolution. The image reader includes a confirmation-signal producing portion which produces a resolution confirmation signal representing a second reading resolution which should be identical with the first reading resolution indicated by the controller. The controller includes a judging portion which receives the resolution confirmation signal from the image reader, and judges whether the second reading resolution represented by the received resolution confirmation signal is identical with the first reading resolution indicated to the image reader. The controller therefore judges whether the first reading resolution has normally been indicated to the image reader.
