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 19):
A code reading device for reading a code on a workpiece, comprising:\n a housing; a window portion provided on a front surface side of the housing and having translucency; a first light emitters provided in the housing and configured to output light; a first polarization filter provided in the first region of the window portion and light output from the first light emitters passing through the first region of the window portion; a second light emitters provided in the housing and configured to output light to an outside of the housing through a second region of the window portion which is a different region from the first region of the window portion and in the absence of any polarization filter, wherein the number of first light emitters is larger than the number of second light emitters; a second polarization filter provided in a third region of the window portion which is a different region from the first region and the second region of the window portion, and a polarization direction of the second polarization filter being different from a polarization direction of the first polarization filter; an imaging section configured to receive light output from the first light emitters or the second light emitters, reflected at the workpiece and through the second polarization filter, and configured to output image data of the code on the workpiece; and a decoding section that decodes the image data acquired by the imaging section.
