Abstract:
1. An image reading apparatus comprising: a first conveyance path configured to convey a sheet; a second conveyance path in which the sheet reversed after passage in the first conveyance path is conveyed; a reading device configured to be capable of reading the sheet at a first position in the first conveyance path and to be capable of reading the sheet at a second position in the second conveyance path; a first conveying device including a first movable unit disposed upstream of the first position in a sheet conveyance direction at the first position and a second movable unit disposed downstream of the first position in a sheet conveyance direction at the first position, the first and second movable unit pinch and move the sheet to cause the sheet to pass through the first position; and a second conveying device including a third movable unit disposed upstream of the second position in a sheet conveyance direction at the second position and a fourth movable unit disposed downstream of the second position in a sheet conveyance direction at the second position, the third and fourth movable unit pinch and move the sheet to cause the sheet to pass through the second position; wherein when the reading device reads the sheet at the first position, a moving velocity of the second movable unit is larger than a moving velocity of the first movable unit, and when the reading device reads the sheet at the second position, a moving velocity of the fourth movable unit is larger than a moving velocity of the third movable unit.
