<P>PROBLEM TO BE SOLVED: To achieve an excellent configuration for potability while maintaining good receiving characteristics when an antenna for broadcast signal reception is not prepared in a portable terminal apparatus. <P>SOLUTION: In a portable radio apparatus which is composed preparing a cradle 2 and the portable terminal apparatus 1, the cradle 2 incorporates the antenna 22 for broadcast signal reception, and prepares a contact 21 for transmitting the received broadcast signal, and a terminal mounting portion 23 for mounting the portable terminal apparatus 1. The portable terminal apparatus 1 prepares a contact 11 which receives the broadcast signal through the contact 21 of the cradle 2, and a broadcast receiving circuit portion 14 which demodulates the received broadcast signal. Moreover, the portable terminal apparatus prepares a band switch circuit portion 12 which carries out band switching of the received broadcast signal, and outputs it to the broadcast receiving circuit portion 14, and carries out switching to a frequency tuned to a band of the receiving broadcast signal. <P>COPYRIGHT: (C)2010,JPO&INPIT |
