- an IC chip (not shown) for proximity non-contact communication connected to the second antennas 14A and 14C in the lid 5A is
- the second antennas 14A-14C are connected in series and serve as an interface. Can be reduced to two.
- the reliability can be improved, and the thickness of the battery unit (battery pack 5) is 1 mm smaller than that of a portable communication device having no proximity non-contact communication function. It can be suppressed to the following up.
- the electromagnetic interference suppression sheets 15A to 15C allow sufficient proximity non-contact communication on a plurality of surfaces without flowing a reverse current in each of the antennas 14A to 14C. In addition to this, it is also possible to prevent high-frequency components radiated as mobile phone signals from jumping into the second antennas 14A-14C.
- the proximity non-contact communication antenna 21 of the external proximity non-contact communication device 2 is Even if the second antennas 14A-14C are not in a parallel relative positional relationship, the proximity non-contact communication can be performed by the second non-contact communication antennas 14A-14C in the cover 5A of the battery pack 5. In addition, proximity non-contact communication can be performed on four sides.
- the second antenna for close contactless communication and the electromagnetic interference suppression sheet are arranged on the lid 5A of the battery pack 5, as in the second embodiment.
- the proximity non-contact communication IC connected to the second antennas 14A to 14C is disposed inside the casing 10 (not shown). Therefore, sufficient security can be ensured without any complicated software measures.
- the proximity non-contact communication function can be used again by using a substitute for the battery pack 5.
- the second antennas 14A-14C for proximity non-contact communication and the electromagnetic interference suppression sheet 15A are provided on a plurality of surfaces of the lid 5A integrated with (the main body of) the battery pack 5.
- the force may be provided on the side of (the body of) the battery pack 5 which is not connected to the lid 5A.
- an external proximity non-contact communication device 2 has been described as an example of a communication partner of the second antennas 14A to 14C for proximity non-contact communication. Limited to this It is possible for the system to be configured so as to perform proximity non-contact communication with an external proximity non-contact communication card.
- the portable communication device of the present invention can form a small proximity non-contact communication antenna for portable communication devices, perform proximity non-contact communication on a plurality of surfaces, and radiate as a radio signal for a mobile phone.
- Mobile communication devices that have the effect of preventing high-frequency components from entering into the proximity non-contact communication antenna, and have a proximity non-contact communication function as well as mobile communication devices dedicated to proximity non-contact communication, such as mobile phones. Useful for telephones, PHS, PDAs, etc.
