SCANNER APPARATUS

摘要

A scanner apparatus comprises a casing having an image capturing window on the front surface thereof, an image capturing section, arranged inside the casing, configured to capture image of an object in a reading area invisibly formed outside the image capturing window of the casing, a plurality of lighting sections, arranged inside the casing, configured to irradiate light to the reading area, part of the light from the lighting sections being reflected on the inner surface of the image capturing window to become a stray light, and a shielding section configured to shield the stray light entering the image capturing section. The plurality of lighting sections mutually compensate the reduction in luminous intensity of the light from the lighting sections in the reading area caused by the shielding section.
