Abstract
An image reading apparatus executes a calibration processing of calibrating a reading unit when a medium detection sensor detects that a medium is present. The image reading apparatus executes the calibration processing each time a first time-period elapses in a state where the medium detection sensor detects that the medium is present after the calibration processing. When a start instruction of reading the medium is received, the image reading apparatus starts transport of the medium and causes the reading unit to read the medium on a basis of calibration information of a last calibration processing.
