PROBLEM TO BE SOLVED: To provide a power generation input device capable of generating electromotive force of large output, without requiring excessive operating force, and to provide an electronic apparatus using the power generation input device.SOLUTION: A first facing end 4a and a second facing end 4b are formed in a magnetic path formation member 3 around which a power generation coil is wound. A rotating body 10 has a permanent magnet 21, a first magnetization member 22 and a second magnetization member 23. When the operating force is not acting on an operation member 15, the end face 22a of the first magnetization member 22 faces the first facing end 4a via a gap, and the end face 23a of the second magnetization member 23 faces the second facing end 4b via a gap. When the operation member 15 is pushed, the rotating body 10 is rotated, and when the force to the operation member 15 is released, the operation member 15 and the rotating body 10 are reset. Since the rotating body 10 does not come into contact with the magnetic path formation member 3, the force required for operation of the operation member 15 is relatively weak, and since the rotating body 10 rotates instantaneously by magnetic attraction, large electromotive force can be obtained.SELECTED DRAWING: Figure 3 |
