PURPOSE:To input rapidly and correctly the correcting surface dimensions by calculating the dimensions of the correcting surface and outputting to a wheel balancer, based upon the length and the rotating angle of the measuring rod to abut the tip to the correcting surface. CONSTITUTION:In the vicinity of the tire rotating shaft of the wheel balancer to measure the unbalance of the tire, a rotatable supporting stand 11 is provided, and at the supporting stand 11, a measuring rod 12 is provided that is rotated as one body with this, formed to the length variable and abutted on the correcting surface of the tire whose tip is fitted with the rotating shaft. Furthermore, the supporting stand 11, a fan-shaped angle plate 14 is provided, and on a substrate 15, a pulse generating device 16 to generate the pulse by the score of the angle plate is provided, and the angle measuring instrument is obtained. Further, at the anti-tire side of the rod 12, a length measuring plate 17 is provided, a pulse generating device 24 to generate the pulse by the score of the length measuring plate is provided and the length measuring machine is obtained. Based upon the position relation of the bearing of the tire rotating shaft and the rotating center of the supporting stand 11, and the measuring value of the length and the rotating angle of the rod 12 to abut the tip on the correcting surface, the dimensions of the correcting surface is calculated by the arithmetic unit and outputted to the wheel balancer. |
