When a push button of a key operation part 15 is pushed down, a portable terminal 1 becomes a master side. The portable terminal 1 displays pointer information of a marker, which is outputted by a pointing device part 18, on a display part 16. The portable terminal 1 transmits the pointer information from a radio part 14 to a PoC server. The PoC server sends the pointer information from the portable terminal 1 to other users' portable terminals in a group. If the pointer is moved, then the portable terminal 1 as a master side repeats the aforementioned processes.
