ABSTRACT:
In case of detecting tire information marks engraved in a side wall portion of tire in the form of protrusion or recess, width and inner diameter of tire are detected to provide a tire size signal, after a first camera head is driven into a given position in accordance with the tire side signal, an identification mark engraved in the size wall portion of tire is optically detected by the first camera head to derive a position signal, and after a second camera head is driven into a given position in accordance with the position signal, the tire information marks are optically detected by the second camera head to derive a tire information signal. In this manner, the tire information marks can be detected in a rapid and accurate manner.
