An image scanner capable of reducing the read time by narrowing the visual field for a small-size electronic component. This image scanner includes a photosensitive element array having a plurality of photosensitive elements arranged in a row which are exposed to light to accumulate charges therein, a shift register for receiving the charges stored in the photosensitive elements and supplying the charges to an output portion, a shift gate for controlling the charges stored in the photosensitive elements to be transferred to the shift register, and a transfer command signal output portion for generating a transfer command signal by which the charges stored in the photosensitive elements are allowed to be transferred to the shift register. In addition, the transfer command signal output portion is able to change the intervals of time at which the transfer command signal is generated.
