When the authentication is performed, the control part 34 controls a main communication part 31 to transmit the main data stored in a storage part 30 to the display device 2 being the writing destination by radio communication. The display device 2 includes a control part 25 which controls an authentication communication part 21 to receive the data for authentication from the writing device 3. The control part 25 controls the main communication part 20 to receive the main data from the writing device 3 by radio communication after the authentication. <P>COPYRIGHT: (C)2010,JPO&INPIT |
