Document Type and Number:
Japanese Patent JP2020162388
Kind Code:
A
Abstract:
To provide a positioning device or the like capable of easily adjusting a mutual positional relationship between a sensor magnet and detection means for detecting a magnetic field generated by the sensor magnet.SOLUTION: A positioning device 500 includes: a regulated power supply 510 for allowing a current to flow through a coil mounted on a housing; and a third LED 533 for detecting a position of a magnetic pole of a sensor magnet rotatably fitted to a rotor having a main magnet arranged to face the coil in a state where the regulated power supply 510 causes a constant current to flow through the coil, and for operating in response to an output signal from a second sensor 512 mounted on the housing.SELECTED DRAWING: Figure 7
