<P>PROBLEM TO BE SOLVED: To provide an electronic apparatus, in which a sensor is mounted for detecting whether an opposed apparatus is in a communicable range of near-field communication of TJ (TransferJet(R)) or the like, for performing power saving control on a near-field communication section by controlling activation of the near-field communication section based on output of the sensor. <P>SOLUTION: A proximity sensor 6 is mounted on the same surface as a TJ coupler 5 and measures a distance to the opposed apparatus. If the distance is within 3 cm, a control section 9 turns on power supply to a TJ circuit 2. If a state where the distance is longer than 3 cm continues for 10sec, a notification is issued to a user to approach. If the distance is within 3 cm and there is no response from the opposed apparatus, a TX3 and an RX4 are periodically turned on, thereby performing power saving of the TJ circuit 2. Furthermore, during the power saving, the user is notified about that the opposed apparatus is not adaptable to TJ. <P>COPYRIGHT: (C)2011,JPO&INPIT |
