1. A remote controller comprising:

  • a mechanical operation unit that generates mechanical energy by being pressed by a user;

    a power generating element that is provided corresponding to the mechanical operation unit and generates electric power by converting the mechanical energy generated by the mechanical operation unit into electric energy;

    an electric circuit that operates by using electric power generated by the power generating element and is able to output a signal of a kind corresponding to a content of each operation on the mechanical operation unit;

    a memory that operates by using electric power generated by the power generating element and nonvolatilely stores a content of an output signal of the electric circuit;

    a wireless transmitter that operates by using electric power generated by the power generating element and transmits a wireless signal including information corresponding to a content of the output signal stored in the memory;

    a switch that is provided on a power supply line from the power generating element to the wireless transmitter; and

    a processor that operates by using electric power generated by the power generating element and is programmed to cause the wireless transmitter to transmit the wireless signal when the operation on the mechanical operation unit satisfies a predetermined condition, andthe processor turns on the switch when the operation on the mechanical operation unit satisfies the predetermined condition to supply the electric power generated by the power generating element to the wireless transmitter and turns off the switch in response to completion of transmission of the wireless signal by the wireless transmitter to stop the power supply to the wireless transmitter.
