Abstract:
A position detection device includes a first magnetic field generation unit for generating a first magnetic field, a second magnetic field generation unit for generating a second magnetic field, and a magnetic sensor. The relative position of the second magnetic field generation unit with respect to the first magnetic field generation unit is variable. The magnetic sensor detects a composite magnetic field of the first and second magnetic fields, and generates a detection signal corresponding to the direction of the detected magnetic field. Varying the relative position of the second magnetic field generation unit with respect to the first magnetic field generation unit varies the strength of the second magnetic field at the detection position. At the detection position, a relative angle formed by the direction of the second magnetic field with the direction of the first magnetic field is greater than 90° and smaller than 180°.

Claim (Index 1):
A position detection device comprising:\n a first magnetic field generation unit for generating a first magnetic field; a second magnetic field generation unit for generating a second magnetic field, the second magnetic field generation unit being provided such that its relative position with respect to the first magnetic field generation unit is variable; and a magnetic sensor for detecting a magnetic field to be detected at a predetermined detection position and generating a detection signal corresponding to a direction of the magnetic field detected, wherein varying the relative position of the second magnetic field generation unit with respect to the first magnetic field generation unit does not vary a strength or direction of the first magnetic field at the detection position or a direction of the second magnetic field at the detection position, but varies a strength of the second magnetic field at the detection position, the magnetic field to be detected is a composite magnetic field of the first and second magnetic fields at the detection position, and at the detection position, a relative angle formed by the direction of the second magnetic field with the direction of the first magnetic field is greater than 90\u00b0 and smaller than 180\u00b0.
