Optical information reader

An optical information reader comprising:

• a housing provided with an optical reading window, the optical reading window serving as a reading surface on or over which an imaging target being optically read is placed outside the housing;
• an illuminant arranged inside the housing;
• a reflective member fixedly arranged and having a predetermined reflective surface reflecting illumination light emitted from the illuminant toward the reading surface;
• an imager arranged inside the housing and configured to receive an image, through the reading surface, of the illumination light reflected by the imaging target on or over the reading surface outside the housing;
• and
• an image former configured to guide the illumination light reflected by the imaging target toward an imaging region of the imager through a stationary spatial imaging region provided among the illuminant, the reflective member, and the reading surface, wherein
• the spatial imaging region includes a first spatial imaging region and a second spatial imaging region, the first and second spatial imaging regions being stationary, the first spatial imaging region being provided between the image former and the reading surface and provided to enable the illumination light from the predetermined reflective surface of the reflective member to be reflected by the imaging target on or over the reading surface toward the image former, the second spatial imaging region being provided between the reading surface and the reflective member and provided to enable the illumination light from the illuminant to be transmitted from the predetermined reflective surface of the reflective member toward the reading surface, and the second spatial imaging region bending on the reading surface toward the imager and continuing to the first spatial imaging region;
• the reflective member is arranged spatially outside the first spatial imaging region in the spatial imaging region;
• the illuminant, the imager and the image former are arranged spatially outside the second spatial imaging region in the spatial imaging region;
• and
• the illuminant emits the illumination light toward the predetermined reflecting surface of the reflective member across the first and second spatial imaging regions.
