<P>PROBLEM TO BE SOLVED: To provide a magnetic guide device capable of performing the traveling guide of a moving body in a non-contact control by constantly performing consistent magnetic control even when a sensor signal is disturbed by the shape or the like of a guide rail. <P>SOLUTION: A signal correction computing element 32 is provided on a control device for controlling the magnetic force of a magnetic guide device. The signal correction computing element 32 performs the differentiation of each of detection signals Ga, Gb of two gap sensors, and integrates the differentiated signal of the smallest absolute value and outputs the integrated value. By using the output signal Gc for the magnetic control, the consistent magnetic control is constantly performed even when the sensor signal is disturbed by the shape or the like of a guide rail, resulting in the traveling guide of a moving body in a non-contact manner. <P>COPYRIGHT: (C)2009,JPO&INPIT |
