る光学的文字読取用ハンドスキャナ。An optical character reader that includes a light source for projection, an image sensor consisting of a group of optical and electrical conversion elements, and an optical system that focuses reflected light from the paper surface on which characters, symbols, etc. are written, onto the image sensor. In a digital scanner, the inner wall at the tip of the scanner is an optical reflective surface, and the inner wall is sloped so that the light emitted from the light source is specularly reflected on the paper surface and is not focused on the image sensor.
