<P>PROBLEM TO BE SOLVED: To solve uncomfortableness caused by illumination light entering a view field of a person around a two-dimensional code reader when the illumination light lighting the two-dimensional code is turned on or flashed always in a fixed type two-dimensional code reader having an upward reading port. <P>SOLUTION: An imaging element acquires optical information as image information of light from the optical information and stores the acquired image in an image storage part. When the image acquired by the imaging element is changed, lighting control is carried out for projecting light to the optical information. In this way, uncomfortableness caused by the illumination light can be prevented. <P>COPYRIGHT: (C)2004,JPO |
