<p>PURPOSE: To discriminate receiving regions more than the number of receiving means. CONSTITUTION: Actuators 12-16 driving each door lock 7-11 of each door 2-6 and a receiving sensor 19 receiving infrared data from a mechanical key 18 are connected to a unit 20 with a CPU. A first light-receiving region C in the first light-receiving element of the receiving sensor 19 is set so as to cover the front left door 2 and rear left door 4 sides, a second light-receiving region D in a second light-receiving element the front right door and rear right door 5 sides and a third light-receiving region E in a third light-receiving element from the rear left door 4 side to the rear right door side. A fourth light- receiving region F, in which the first light-receiving region C and the third light-receiving region E are overlapped, is formed on the rear left door 4 side and a fifth light-receiving region G, in which the second light-receiving region D and the third light-receiving region E are overlapped, on the rear right door 5 side.</p> |
