PROBLEM TO BE SOLVED: To provide an optical information reading device capable of optically reading an information code moved at a high speed, without requiring an external trigger.SOLUTION: A marker M moved together with an information code C is displayed so as to obtain a predetermined positional relation with respect to the information code C. When it is determined that the marker M is imaged by determination processing, the imaging timing of imaging the information code C according to the marker M is set by imaging timing setting processing and an image signal is fetched from a light-receiving sensor 28 at the imaging timing, so that the imaged information code C is decoded by decoding processing.SELECTED DRAWING: Figure 4 |
