Abstract
An image reading apparatus includes a plurality of image reading chips. Each of the plurality of image reading chips includes, a pixel that includes a light receiving element which receives light and performs photoelectric conversion; a voltage boosting circuit that generates a transmission control signal for transmitting electric charges which are generated on the basis of the photoelectric conversion; and a reading circuit which generates an image signal on the basis of the electric charges which are transmitted. The voltage boosting circuit operates during a period in which the light receiving element receives the light and during a period in which the electric charges that are generated on the basis of the photoelectric conversion which is performed by the light receiving element, and stops an operation during a period in which the reading circuits of the other image reading chips output the image signals.
