<p>PURPOSE:To perform the position detection of a heating body highly accurately regardless of the dispersion of the detection timing of an HMD generated by the temperature change of the heating body. CONSTITUTION:With a target-distance setting part 9, the correcting value outputted from a correcting-distance operating part 8 and a predetermined physical distance are added, and a target distance is set. Whether the conveying amount of a heating body, which is detected with a conveying-distance detector 3, has reached the preset target distance or not is monitored with a comparator 10.</p> |
