Image reading apparatus

An image reading apparatus, comprising:

• an image sensor configured to read an image on an original;
• an original tray on which the original is to be placed;
• a conveyor configured to convey the original placed on the original tray to a reading position in which the image sensor reads the original;
• a first original sensor provided between the original tray and the reading position and configured to assume a first state when the first original sensor detects the original that is being conveyed by the conveyor and assume a second state when the first original sensor does not detect the original;
• a second original sensor provided downstream of the first original sensor in a conveyance direction of the original between the original tray and the reading position and configured to assume a first state when the second original sensor detects the original that is being conveyed by the conveyor and assume a second state when the second original sensor does not detect the original;
• a first distance detector configured to measure a first conveyance distance of the original by which the original has been conveyed from a time when the first original sensor is changed from the first state to the second state;
• a second distance detector configured to measure a second conveyance distance of the original by which the original has been conveyed from a time when the second original sensor is changed from the second state to the first state before the first original sensor is changed from the first state to the second state;
• and
• a controller configured to control the conveyor so that:
• the conveyor starts a conveyance of a succeeding original in a case where the succeeding original is on the original tray when the second conveyance distance reaches a conveyance permission distance while the first original sensor remains in the second state after the first original sensor changes from the first state to the second state and before the first conveyance distance reaches a hole detection distance;
• and
• the conveyor stops the conveyance of the succeeding original in a case where the first original sensor changes from the second state to the first state after the conveyance of the succeeding original is started and before the first conveyance distance reaches the hole detection distance, and thereafter starts the conveyance of the succeeding original when the first conveyance distance reaches the hole detection distance.
