Abstract: A magnetic detection apparatus detects movement of an object having a nonuniform system of teeth by means of magneto-electric conversion devices, wherein technical problems such as too large an amplified output signal, a nonuniform pulse period and a complicated circuit configuration can be solved. A plurality of uniform triangular teeth are formed on the circumference of a gear at equal angular intervals, and in a predetermined region a trapezoidal tooth is formed, where the height of the trapezoidal tooth is smaller than the height of the uniform teeth but greater than half their height. The magnetized surface of a bias magnet facing the gear generates a bias magnetic field directed toward the gear. Magneto-resistive devices are provided in the bias magnetic field. Variations in state of the bias magnetic field generated by the bias magnetic magnet when the gear is rotated are converted into an output electrical signal by the magneto-resistive devices.

Abstract: In a magnetism detecting apparatus, a magnetoresistance element is positioned adjacent to a gear with teeth to be responsive to magnetic field applied thereto. The gear is shaped such that each of the teeth satisfies SA/(SA+SB)<0.125, where SA denotes a cross-sectional area of a tip portion of each of the teeth, which tip portion is measured through 10% of a height of each of the teeth taken from a tip of each of the teeth, and SB denotes a cross-sectional area of a notch portion of each notch between the teeth, which notch portion has a height corresponding to the height of the teeth. As a result of this configuration, distortion contained in an output signal based upon high and low threshhold values from the magnetoresistance element can be eliminated. In addition, variations in intervals of a pulse signal obtained by performing a waveform shaping operation can be reduced, even when a distance between the gear teeth and the magnetoresistance element is varied.
