| 主权项 | 1. An electronic device, comprising: a main body; a movable unit connected to the main body and rotatable around a first axis as a rotation center with respect to the main body; a magnetic field generating member provided in the main body; and a magnetic field detection sensor arranged in a position on a straight line parallel with the first axis and extending on the first axis, wherein in a case that the movable unit is rotated around the first axis as the rotation center with respect to the main body, a direction of a magnetic field that can be detected by the magnetic field detection sensor changes and an output signal of the magnetic field detection sensor changes. | ||
