<P>PROBLEM TO BE SOLVED: To provide a tilt sensor that can decrease the number of components and achieve downsizing. <P>SOLUTION: The tilt sensor includes a disk-like moving body 1 including a conductive material, a guide body 2 fixed to an object and provided with a V-shaped guide path 20 in which the moving body 1 is displaceable, and a detection part 5 having coils provided respectively at positions opposed to both ends that the moving body 1 reaches when the object is tilted at a predetermined angle or greater in the guide path 20, and detecting a fall-down state in which the object is tilted at the predetermined angle or greater based upon impedance variation of one of the coils due to the displacement of the moving body 1 to the position opposed to the coil. The coils comprise coil patterns 52 formed on a printed wiring board 50 arranged in the guide body 2 and mounted with a circuit component 51 of the detection part 5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
