PROBLEM TO BE SOLVED: To provide an optical information verifier capable of shortening the verification time of information code displayed on a display surface of a display medium.SOLUTION: Feeding speed V at which a print label 12 to be verified is continuously fed is decelerated from verification time feeding speed Vo (or in a stopped state). Based on the picked-up image by the image pickup processing, the specified information of the information code (bar code B) displayed on a display surface 13 of the print label 12 is specified, and stored in a storage unit 24. Each display state of the information code included in the picked-up image in which the image of each display surface 13 is picked up for the print label 12 to each print label 12 to be continuously fed at the verification time feeding speed Vo is verified based on the specified information stored in the storage unit 24. |
