<p><P>PROBLEM TO BE SOLVED: To transmit an infrared signal from a control module to an infrared receiving element in every movement module with no ununiformity for receiving the light. <P>SOLUTION: The vehicle indicator is provided with a processing means DP for processing measurement data indicating the vehicle condition to convert it to vehicle condition indication data by an electric signal S1, light-emitting an infrared light emission element LED based on this electric signal S1 and transmitting the vehicle condition indication data by an infrared signal Sinf; a plurality of indication means DIS for receiving the transmitted infrared signal Sinf and converting it to the vehicle condition indication data to indicate it. The processing means DP controls a period per unit time of the electric signal for driving the infrared light emission element and shortens a light emission time per unit time of the infrared light emission element LED. <P>COPYRIGHT: (C)2004,JPO</p> |
