PURPOSE:To obtain a tire discriminating device that outputs a correct result of discrimination when automatically discriminating the type of a tire and is relatively simple in construction. CONSTITUTION:Graphics, such as recessed and projected characters Ch, are picked up by emitting a light to a tread side face TS of a tire T. The image data thereof is received by a control means (e). The data is collated with a graphic data group, such as registered characters. In accordance with the result of recognition, the type of the tire is judged. In addition, for the ease of recognition of characters (graphics), a shade S of an appropriate size is formed at the edge of the recessed and projected characters Ch by adjusting an angle of projecting a light on the tread side face TS. |
