Title:
INDUCED CURRENT POSITION DETECTION APPARATUS WITH CORRECTED PITCH
Document Type and Number:
Japanese Patent JP3420948
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an induced current position detection apparatus that is accurately measured, manufactured at low cost, resistant to pollution, and outputs a substantially balanced signal without inconvenienced being adversely affected by the pitch-shift.
SOLUTION: A transmitter winding 610 generates variable magnetic flux. To prevent each part 626, 633, and 637 of a first and a second receiver windings 620, 630 from forming a loop, the parts 626, 633, and 637 include two wires mutually overlapped and form no loops. To switch the receiver windings 620, 630 to both sides of a printed circuit board 650, multiple through holes 652 are installed in the printed circuit board 650. This arrangement provides an insulated intersection in overlapping parts between loops 622, 624, 636, and 638 of the first and the second receiver windings 620, 630.
