Abstract
In an image reading apparatus, a retreat control device moves a conveyance target through a conveyance mechanism, when a stop operation is performed by a stop control device, in an opposite direction to an image reading direction to a position further from a restart reference position set by a position setting unit. A reading control device again moves the conveyance target, which has been moved by the retreat control device, at a constant speed in the image reading direction under a predetermined condition; inputs a line start signal to a reading unit when an offset time set by a time setting unit has elapsed from a time point when the conveyance target reaches the restart reference position; and periodically inputs a line start signal to thereby cause the reading unit to perform a reading operation from a point; where the reading unit is located when the offset time has elapsed.
