PROBLEM TO BE SOLVED: To clarify the operation display of a portable communication terminal. SOLUTION: An antenna 20 that resonates a calling from the portable communication terminal B, an electronic circuit 30 and a light emitting element LED is incorporated in a case 23. The antenna 20 performs electromagnetic coupling with an antenna 10 and induces large output voltage by attaching the antenna 20 to the antenna 10 of the terminal B through the case 23, and the circuit 30 can make lighting quantity of light sufficiently large by rectifying it and amplifying it. |
