Abstract

PURPOSE: To obtain a high-reliability mark detection method by compressing two rollers to the side wall face of a tire to make the side wall face between rollers plane and holding the gap between the sensor and the side wall face constant.
CONSTITUTION: Two rollers 760 and 760' arranged in parallel approximately along the diameter direction of a tire are compressed to the side wall 1c face of the tire while rotating the tire. Mark detector frame body 761 is provided on rollers, and detection unit 762 equipped with reflection-type photoelectric sensor 763 consisting of a light source and a photo detection element is held between frame body 761 and rollers 760 and 760'. Rollers 760 and 760' and guide roller 764 press side wall face 1c of the tire and beat face 1a of the tire respectively to make a part of face 1c into a plane, and gap d between sensor 763 and the side wall face is always held constant, and the distance from face 1a to sensor 763 is held constant. Thus, cheap and high-reliability mark automatic detection can be performed.
