Claims
- 1. An optical reading apparatus for reading a linear recording printed on an information recording surface, the optical reading apparatus comprising:
- a plurality of light emitting elements for emitting light beams in different directions toward the information recording surface;
- a light receiving element for receiving reflected light from the information recording surface and for generating a recording read signal;
- a signal processing section for converting the recording read signal from said light receiving element into a display signal; and
- a controlling driving section for driving said plurality of light emitting elements;
- wherein said plurality of light emitting elements are driven by said controlling driving section so as to emit intermittent light beams at timings different from each other; and
- wherein said signal processing section includes a plurality of conversion processing routes, each of the conversion processing routes including means for individually performing conversion processing of a plurality of recording read signals obtained from one said plurality of light emitting elements, said signal processing section selectively extracting and outputting, as a display signal, a selected one of the recording read signals obtained by the conversion processing by a selected one of said plurality of conversion processing routes which omits a regular reflection condition.
- 2. An optical reading apparatus according to claim 1, wherein the selected recording read signal extracted as a display signal by said signal processing section is one of the recording read signals which has been decoded regularly upon decoding of the plurality of recording read signals.
- 3. An optical reading apparatus according to claim 1, wherein said signal processing section detects occurrence of a regular reflection condition from the plurality of recording signals, and the selected recording read signal is one of those of the recording read signals from which occurrence of a regular reflection condition is not detected.
- 4. An optical reading apparatus according to claim 1, wherein the linear recording is a bar code, and said optical reading apparatus is a bar code reader.
