To reduce the effect to a stepping motor in the case of collision of tips of recording paper in the case where tips of recording paper collide with a 2nd carrier roller, an angular velocity speed of the stepping motor is affected to provide effect onto a read image.
A motor drive section 59 drives a stepping motor 56 by a signal of a predetermined 1st drive frequency and a 1st carrier 52 carries an original 50. After the original 50 is caught by the 2nd carrier rollers 54, a motor drive section 59 drives the stepping motor 56 with a signal of a predetermined 2nd drive frequency higher than the 1st drive frequency after the elapse of a prescribed time to reduce the fluctuation in the load of the 2nd carrier rollers 54 due to collision of tips of the original 50.
