Light emission data are read in accordance with the reproduction start of the music data. After the start of reading the light emission data by a control circuit 22 in accordance with the reproduction start of the music data, it is determined whether the light emission instruction timing has come or not. When it is determined that the light emission instruction timing has come, the light emission instruction signal of the light emitting part 33 is output for the light emitting tag T by using the device antenna 3. <P>COPYRIGHT: (C)2011,JPO&INPIT |
