Abstract
An image reading apparatus includes a driving source, a conveying mechanism, a reading control unit, an acceleration distance measuring unit, an interruption determination unit, a stop control unit, a deceleration distance measuring unit, a setback control unit, and a setback distance setting unit. The acceleration distance measuring unit measures an acceleration distance from a moving start position of a conveyed object to a position where the conveyed object has been shifted to the constant-velocity moving state. The deceleration distance measuring unit measures a deceleration distance from a position of the conveyed object when operation of the reading control unit has been stopped to a position where move of the conveyed object in a conveyance direction has been stopped. The setback distance setting unit sets a setback distance to move the conveyed object by the setback control unit based on the acceleration distance and the deceleration distance.
