<p>PROBLEM TO BE SOLVED: To make it possible for a single detection switch to severally detect an opening/closing action of an opening/closing member which severally performs an opening/closing action about at least two hinge shafts, and achieve reduction in the number of components, simplified structure, and cost reduction.SOLUTION: An opening/closing detector comprises: an opening/closing member 2 which severally performs opening/closing action to a body 1 about at least two hinge shafts 4a, 5a; and an opening/closing detection switch 6 which detects each opening/closing action of the opening/closing member 2 about the hinge shafts 4a, 5a by a single movable sensor 6a at contact positions of the body 1 with respect to the opening/closing member 2. For example, the opening/closing detection switch 6 is arranged at approximately central position between at least the two hinge shafts 4a, 5a. Then, the movable sensor 6a performs rotary movement about an axis line orthogonal to at least one hinge shaft out of at least the two hinge shafts 4a, 5a.</p> |
