PROBLEM TO BE SOLVED: To provide an optical information reading device in which influence of illumination light caused by irradiation error can be prevented.SOLUTION: By reading processing executed by a control circuit 40, on the basis of an acceleration signal outputted from a three-axis motion sensor 50, whether an optical information reading device 10 is in a still state of being still or a non-still state of not being still is determined, and irradiation of illumination light Lf of an illumination light source 21 is stopped at the time of determining the non-still state so as to be lower than illuminance of the illumination light Lf of the illumination light source 21 at the time of determining the still state. |
