Abstract

PURPOSE: To enhance accuracy, viewability, and reliability for direction indicator, earth magnetism detection and its indication are electronically treated.
CONSTITUTION: Magnetic sensor 1 has two nearly perpendicularly crossed detection axes and produces electric outputs ex, ey of external magnetic components which correspond to the detection axes. The magnetic sensor 1 is connected to amplifiers 21, 22, coefficient calculators 71 to 74, comparators 81 to 88, photoemitting elements 31 to 38. Thus, outputs ex, ey from the magnetic sensor 1 are amplified, multiplied by coefficient α(=tan67.5°≃2.414), 1/α, -1/α, -α by the coefficient calculators 71 to 74, and compared each other by the comparators 81 to 88. This finds the zone to which the measurement belongs, from 8 zones determined by 4 straight center-passing lines. The result is indicated by lighting one of photoemitting elements 31 to 38 so that lighting corresponds to measured zone.
