Abstract
An image reading apparatus, including: a first distance detector configured to measure a first distance of the original conveyed after a sensor is changed from a first state detecting the original to a second state not detecting the original; a second distance detector configured to measure a second distance of the original conveyed after the second state is changed to the first state; and a controller configured to control a conveyor so that the conveyor starts a conveyance of a succeeding original when the second distance reaches a conveyance permission distance before the first distance reaches a hole detection distance and the conveyor stops the succeeding original when the second state is changed to the first state before the first distance reaches the hole detection distance, and thereafter starts the conveyance of the succeeding original when the first distance reaches the hole detection distance.
