ABSTRACT OF THE DISCLOSURE An image reading apparatus is provided with a device for emitting a light to an original, and a solid state image sensor such as a CCD sensor, for receiving a reflected light from the original and transferring out a light information signal corresponding to the received light integrated during a predetermined transferring cycle. The image reading apparatus is also provided with a device for controlling the emitting device so as to emit the light during a time interval which is more than twice of the predetermined transferring cycle, and further controlling the solid state image sensor so as to transfer out a first light information signal integrated during a first interval of the time interval and transfer out a second light information signal integrated during a second interval of the time interval after the first interval, in such a timing that a residual image signal of the first light information signal is superimposed on the second light information signal. 26
