OPTICAL CODE PHOTOGRAPHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an information code photographing device by which a distinct video with little noise is obtained even when it is an information code described on a mirror surface body and coated with a transparent thin film.

SOLUTION: The information code photographing device has a camera with built-in image sensor and a photographic auxiliary tool attached to the edge of the camera. The photographic auxiliary tool includes a hood to intercept external light, an illuminator to obliquely illuminate a subject positioned at a specified distance ahead of the optical axis of the camera from a direction different from the optical axis of the camera and a regularly reflected light guiding optical system to guide regularly reflected light obliquely reflected on the surface of the subject to the camera while making a detour.
