Apparatus using fuel gas

An apparatus using fuel gas supplied from an external fuel gas supply device, comprising:

• a battery for supplying power to a device/devices of the apparatus;
• a fuel gas reservoir unit for reserving fuel gas supplied from the fuel gas supply device;
• a fuel lid for covering a supply inlet to which fuel gas is supplied from the fuel gas supply device;
• means for detecting an open/close state of the fuel lid;
• means for detecting fuel gas condition that is a pressure and/or a temperature of fuel gas reserved in the fuel gas reservoir unit;
• means for performing communication with the fuel gas supply device;
• and
• means for, upon reception of a signal notifying that the fuel lid is in an open state from the means for detecting an open/close state, controlling dispensing communication, using power supplied from the battery, in order to notify the condition of the fuel gas having been input from the means for detecting fuel gas condition to the fuel gas supply device via the means for performing communication,
• wherein the means for controlling stops the dispensing communication when the means for controlling has determined, according to a signal received from the means for detecting an open/close state, that a predetermined time period has elapsed with the fuel lid remaining in the open state after starting the dispensing communication, and
• the means for controlling starts the dispensing communication when an ignition switch is turned off after the ignition switch is turned on.
