A data symbol reader for reading a one-dimensional data symbol and a two-dimensional data symbol includes first and second image pickup devices, both having a light receiving surface to receive light reflected from the one-dimensional and two-dimensional data symbols. An optical system respectively converges images of the one-dimensional and two-dimensional data symbols onto the light receiving surfaces of the first and second image pickup devices. A signal processing device is provided for decoding the one-dimensional and the two-dimensional data symbols from outputs of the first and second image pickup devices.
