Claim:
1. A radio communication apparatus that performs radio communication with another radio communication apparatus while receiving radio electric supply from the other radio communication apparatus, the radio communication apparatus comprising: a radio communication section that performs the radio communication with the other radio communication apparatus in line of sight; a radio electric reception section that receives the electric supply from the other radio communication apparatus, using radio; a radio communication control section that controls the radio communication section; and a secondary battery that charges electric power received by the radio electric reception section, wherein when the radio communication section is in a stop state in which the radio communication is not taking place with the other radio communication apparatus, the radio communication control section controls the radio communication section to start the radio communication with the other radio communication apparatus or to maintain the radio communication section in the stop state based on an electric reception level of the electric supply from the other radio communication apparatus, when the electric reception level is equal to or greater than a first threshold, the radio communication control section controls the radio communication section so that the radio communication with the other radio communication apparatus starts, when the electric reception level is less than a second threshold smaller than the first threshold, the radio communication control section determines whether a residual quantity of the secondary battery is less than a third threshold, and when the residual quantity of the secondary battery is less than the third threshold, the radio communication control section controls the radio communication section so that the radio communication with the other radio communication apparatus stops, and when the residual quantity of the secondary battery is not less than the third threshold, the radio communication control section controls the radio communication section so that the radio communication with the other radio communication apparatus continues.
