Optical code reader

The optical code reader includes a light-receiving region limiting optical member 122. The light-receiving region limiting optical member 122 is disposed between a transparent window 8 and an image sensor 102 and includes an imaging lens 100 for imaging reflected light received through the transparent window 8, on a light receiving surface 108 of the image sensor 102. The light-receiving region limiting optical member 122 forms an image Im(1) of an optical code Co in a first light receiving region 108(1) of the light receiving surface 108 and forms an image Im(2) of an optical code Co in a second light receiving region 108 (2) that is different from the first light receiving region 108(1). The image sensor 102 is disposed obliquely to a direction orthogonal to an optical axis Oax of the imaging lens 100.
