发明名称 Electronic musical instrument
摘要 Fuel battery generates electric power using a predetermined fuel, and activation and deactivation of the electric power generation can be controlled in accordance with whether or not the fuel should be supplied to the fuel battery. The electric power is supplied to individual circuits/devices of a tone generation section, so that a tone is generated by any of the circuits/devices operating in response to operation of a performance operator unit. The circuits/devices are allowed to electrically operate for a long time with the electric power supplied by the fuel battery. In this way, an electronic musical instrument using the fuel battery can operate for a long time as compared to the conventional electronic musical instruments using a dry battery or storage battery (secondary battery).
