<P>PROBLEM TO BE SOLVED: To reduce the cost of electric component control equipment by simplifying a constitution of the electric component control equipment which makes the plurality of electric components operated by a single operation unit. <P>SOLUTION: A plurality of switches SW1-SW12, which are provided in the operation unit 22 provided in an operator's seat, are connected to shift registers 31 and 32, respectively. Any one of a plurality of power window motors 12-15 is provided with a main control circuit 71. When a load signal is input from the main control circuit 71, operation signals of the respective switches SW1-SW12 are held by the shift resisters 31 and 32. When a shift signal is input from the main control circuit 71, the operation signals of the shift resisters 31 and 32 are output in a predetermined order; and the main control circuit 71 reading the operation signals discriminates among the power window motors 12-15 corresponding to the respective operation signals, on the basis of order of reading, and outputs desired control signals into the power window motors 12-15 subjected to discrimination. <P>COPYRIGHT: (C)2008,JPO&INPIT |
