<P>PROBLEM TO BE SOLVED: To perform correct detecting operation as a whole even if a part of a weight detecting sensor is failed, by providing the weight detecting sensor with redundancy. <P>SOLUTION: A weight detecting sensor 2 includes a first tape switch group 6 and a second tape switch group 8 that are vertically arranged. Both the tape switch groups are connected in series as an electric circuit, and a voltage of a voltage line 20 for detection where a voltage is applied to a detection relay 14 is applied between the first and second tape switches connected in series. <P>COPYRIGHT: (C)2013,JPO&INPIT |
