PROBLEM TO BE SOLVED: To provide an image reader capable of accelerating image reading processing and reducing the cost of a device used in image signal processing or the like. SOLUTION: This image reader has a plurality of sensor IC chips 2 provided with a built-in a plurality of photodetectors and configured so as to output an image signal corresponding to received light quantity with serial analog signals when the plurality of photodetectors receive light from an object to be read, wherein the plurality of sensor IC chips 2 are arranged in a line shape. The number of the plurality of sensor IC chips 2 is defined as natural number multiple as large as three, the plurality of sensor IC chips 2 are divided into blocks B1 to B3 of natural number multiple as large as three, and the image signal is outputted to each of the blocks B1 to B3.
