Abstract:
Provided is an optical information reading device that can reduce an installation load on a user, and can accurately read a code provided to each of various workpieces. A polarized illumination light source includes light emitters that irradiate the workpiece with illumination light through a polarization filter. A non-polarized illumination light source includes light emitters that irradiate the workpiece with illumination light without through a polarization filter. An imaging element is provided with a polarization filter having a polarization direction different from a polarization direction of the polarization filter of the light emitters. Either of the polarized illumination light source and the non-polarized illumination light source is used in accordance with the workpiece.

Claim (Index 26):
The code reading device according to  claim 19 , further comprising:\n a reading condition control section that controls a reading condition including an imaging condition of the imaging section and an image processing condition in the decoding section, wherein the reading condition control section executes coarse adjustment of a brightness parameter in the reading condition with respect to each of a polarization mode and a non-polarization mode to determine in which of the polarization mode and the non-polarization mode the decoding succeeds more, and further executes fine adjustment of the brightness parameter with respect to the mode in which the decoding succeeds more between the polarization mode and the non-polarization mode, the polarization mode being a mode in which the first light emitters is lighted and the second light emitters is not lighted, the non-polarization mode being a mode in which the first light emitters is not lighted and the second light emitters is lighted.
