A bar code reading apparatus includes a light source device including at least one laser diode light source and having a function of emitting a plurality of laser beams, a mirror device, allowing the laser beams to pass therethrough, and directing reflected light in a specific direction, a deflection device having a deflector for receiving the laser beams passing through the mirror device and forming scanning lines for scanning a bar code symbol on an object to be read, a photoelectric transducer device for receiving reflection light corresponding to the laser light reflected by the object to be read through the deflection device and the mirror device, and a decoding device for decoding a signal obtained by the photoelectric transducer device. The laser beams radiated from the light source devices are emitted at different timings. The decoding device decodes the signal obtained by the transducer device in accordance with the timings of the laser beams emitted from the light source device.
