Title: Magnetic position detector
Inventor: WAKIYAMA KOJI
IPC: G01B7/00
Filed: 2002-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic position detector which can detect the reference position highly accurately.  <P>SOLUTION: In a magnetic position detector which detects the position of a moving body 2 with respect to a stationary body 1 based on the change in density of magnetic flux sensed by a Hall element 4 when the moving body 2 provided with a magnet 6 and the stationary body 1 provided with the Hall element 4 relatively move, the south and north poles of the magnet 6 are aligned with each other along a direction in which the magnet 6 and the Hall element 4 relatively move. When the Hall element 4 passes through the boundary position between the south and north poles of the magnet 6, the magnetic flux density sensed by the Hall element 4 becomes zero, and the polarity of the magnetic field is completely reversed. Thus, the variation of the position where the magnetic flux density sensed by the Hall element 4 becomes zero is completely eliminated. The comparison is made between a detection signal according to the magnetic flux density sensed by the Hall element 4 and the reference signal only for a certain period during which the magnet 6 and the Hall element 4 are close to each other to detect the position where the levels of the two signals are equal to each other, thereby detecting the reference position highly accurately.  <P>COPYRIGHT: (C)2004,JPO
