<p>PURPOSE: To simplify the structure of a remote controller, by providing at least one light-emitting element and one sound-generating element in a response information means of a portable device for wireless communication and combining the emitting motion of the light-emitting element and the generating motion of the sound-generating element for information. CONSTITUTION: In a key unit 19, a personal identification signal is through radio to a main control unit 20 with a transmission circuit 28 in correspondence with switch 22, 23 operation. In the control unit 20, the ID code of the personal identification signal which has received in the receiving circuit 34 is compared with the ID code in the memory by the control circuit 33. When both ID codes coinside with each other, a specified motion like unlocking of the door lock is executed by the actuator 43. And various conditions including results of motions are detected by a detection switch 43 and these response signals are transmitted through the transmission circuit 35 by radio. When the receiving circuit 29 catches the response signals, various conditions are informed by the combination of motions of LED 24, 25 and a buzzer 26. In this way, various conditions can be informed by a small number of elements.</p> |
