Abstract:
1. A power generation input device comprising: a magnetic path forming member comprising a magnetic material; a first opposing end surface and a second opposing end surface that are a portion of the magnetic path forming member and opposed to each other with a space interposed in between; a power generation coil wound on the magnetic path forming member between the first opposing end and the second opposing end; a rotating body positioned in the space to rotate about a shaft which is orthogonal to the opposing direction of the first opposing end and the second opposing end as a support point; and an operating member providing a rotation force to the rotating body, wherein the rotating body has a magnet having a first magnetization surface and a second magnetization surface which become reverse magnetic poles to each other, a first magnetization member that is fixed at the first magnetization surface and comprised of a magnetic material, and a second magnetization member that is fixed at the second magnetization surface and comprised of the magnetic material, and the rotating body is reciprocally rotated by the operating member between a first posture and a second posture, wherein in the first posture, an end of the first magnetization member is opposed to the first opposing end via a gap and an end of the second magnetization member is opposed to the second opposing end via a gap, and in the second posture, the end of the first magnetization member is opposed to the second opposing end via the gap and the end of the second magnetization member is opposed to the first opposing end via the gap.
