A standard omnidirectional barcode scanner, including at least a casing and an electric circuit device, which is used to read one-dimensional bar codes and two-dimensional bar codes, and wherein an electric circuit device is formed with a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor made up of a plurality of linear CCDs or linear CMOSs arranged in an annular array at angular intervals. Each of the linear CCDs or linear CMOS is made up of a linear arrangement of a fixed number of optical sensors, thereby enabling the CCD image sensor or CMOS image sensor capture one-dimensional bar codes or two-dimensional bar codes at different angles, and substantially increasing reading time efficiency.
