Title:
PROPELLING DEVICE
Document Type and Number:
Japanese Patent JP3397641
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a propelling device which can grasp the propelling situation accurately irrespective of the initial setting condition of a magnetic field sensing means.
SOLUTION: A propelling device includes an initially sensed value correcting means 25 which corrects at the time of starting of propulsive motion of a propulsive element 3, the magnetic field sensing values given by a pair of sensing means 23 and outputs them to a display part 7 so that the displayed position of the propulsive element 3 is put identical to the scheduled propelling line on the display part 7. A corrective amount modifying means 26 decreases the rate of correction of the sensing value of magnetic field in association with approaching to the target position for propelling P2 of the element 3 on the basis of the sensing result of a propelling distance sensing means 29.
