<P>PROBLEM TO BE SOLVED: To provide a communication control apparatus capable of reducing current consumption. <P>SOLUTION: A receiving circuit 12 controlled in a receiving/non-receiving state by a control part 14 inputs an electric signal converted from a radio wave signal (a) from an antenna 41 in a rise period of its own power ON in which the circuit 12 is turned to the receiving state, accepts the electric signal when the signal level of the electric signal is a reference voltage Vs level of a reference voltage part 17 arranged on the external and more, and after performing prescribed processing, outputs the processed signal. A signal judgment part 43 judges whether the output signal is a regular signal or not and the control part 14 receiving a judgment result indicating the regular signal continues the receiving state of the receiving circuit 12 for a period required for receiving the whole radio wave signal (a) to constitute the communication control apparatus 10. <P>COPYRIGHT: (C)2008,JPO&INPIT |
