Abstract

PURPOSE: To make it possible to display bearings of the direction of a substrate on a basis of outputs of the first and the second earth magnetism detectors, by providing these detectors on the substrate rotated in an approximately horizontal face.
CONSTITUTION: Magnetism detectors 3X and 3Y are arranged on common substrate 1 so that the angle between directions of Hall effect elements 2X and 2Y may be approximately 90. When substrate 1 is rotated, voltages of magnetism detectors 3X and 3Y, consequently, Hall elements 2X and 2Y are changed by the influence of the earth magnetism. When these voltages are inputted to oscilloscope 13, bearings of the direction of substrate 1 are displayed on display face 15.
