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 28):
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, and in the coarse adjustment, the reading condition control section executes code search processing of searching for the code from the image data in one of the polarization mode and the non-polarization mode, when the code is found by the code search processing, the reading condition control section switches to the other mode of the polarization mode and the non-polarization mode to again execute the code search processing, and when the code is not found in the other mode, the reading condition control section stops the adjustment of the reading condition in the other mode to execute the adjustment of the reading condition on the one 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.
