Abstract: An input apparatus includes a first operation section configured to receive a push operation, a second operation section configured to receive a push operation, a first pivot member configured to pivot, a second pivot member configured to pivot, a first switch, a second switch, and a power generation device. The power generation device is configured to generate electric power when the first pivot member pivots. When the first operation section is pushed, the first switch is turned ON and the first pivot member directly receives force from the first operation section to pivot. When the second operation section is pushed, the second switch is turned ON and the first pivot member indirectly receives force from the second operation section via the second pivot member to pivot.

Abstract: A power generation device includes a power generator that has a cantilever structure of which one end is a fixed end to be fixed and other end is a free end, and generates a power due to free vibration of the free end, a resin holder section on which the power generator is mounted, and a metallic rigid plate that is located such that the holder section is between the rigid plate and the power generator. The fixed end and the holder section are fixed to each other, and the holder section and the rigid plate are fixed to each other.

Abstract: A power generation device of the present disclosure has a start-up unit that has an attraction body and moves from a start point toward an end point, and a power generation unit that generates electricity by being vibrated and has a cantilever shape. Then, the attraction body attracts the power generation unit when the start-up unit moves from the start point toward the end point, the power generation unit deflects and inclines due to movement of the attraction body of the start-up unit and the power generation unit toward the end point while the power generation unit is attracted to the attraction body, the power generation unit starts to vibrate by separation of the attraction body from the power generation unit, and the attraction body inclines in a direction along an inclination of the power generation unit.

Abstract: A power generation device includes a power generator and an activator. The power generator includes a piezoelectric element and a first attraction part provided on the piezoelectric element. The piezoelectric element generates power by vibration. The activator warps the piezoelectric element by moving a second attraction part attractingly contacting the first attraction part from a first position to a second position. The piezoelectric element warped by the activator vibrates when attractingly contacting between the first attraction part and the second attraction part is released. The second attraction part of the activator moves to the second position separated from the first attraction part when attractingly contacting of the first attraction part is released. The activator moved to the second position returns to the first position by magnetic attraction force while the first attraction part and the second attraction part are separated away from each other.
