Abstract
PURPOSE: To enable precise measurement of thickness by automatically correcting the running error, by detecting and storing the running error of transmitter and receiver, and correcting the results of measurement of the measuring object on the basis of stored running error.
CONSTITUTION: A transmitter and a receiver placed opposedly on the face and back of the measuring object are moved in synchronism at right angle to the running direction of the measuring object to measure the thickness of the measuring object. At this time, in the first process, in the absence of the measuring object, the transmitter 31 and receiver 32 are synchronized and moved by a driving unit 2, and the data of running error when the thickness information from a position oscillation device 7 is 0 is stored in a memory unit 10. In the second process, the thickness of the measuring object is measured. In the third process, the result of measurement obtained in the second process is operated and corrected according to the data stored in the first process, then the signal after correcting the running error is delivered.
