ABSTRACT:
An optical reading apparatus for optically reading information of a symbol on an article is comprised of a bar code reading circuit for emitting laser beams to a bar code printed on a commodity passing in front of the bar code reading circuit and for reading the information of the bar code from the laser beams reflected at the bar code. In the optical reading apparatus the bar code reading circuit includes a plurality of bar code readers which are put toward a path through which the commodity is moved so that read areas formed by the bar code readers contain the article moving path at different angles. A priority decision circuit is provided for applying a selective operation to the data read by the bar code readers.
