<p><P>PROBLEM TO BE SOLVED: To provide a disconnection detecting device capable of accurately detecting disconnection, even if the length of a power supply path and a conductor resistance value thereof vary. <P>SOLUTION: A disconnection detecting device 1 includes: a power supply portion 100 for supplying power; a power receiving portion 300 to which power is supplied from the power supply portion 100; a cable 200 connecting the power supply portion 100 and the power receiving portion 300; an A/D converter 302 for detecting the voltage of the power receiving portion 300; a memory which is not shown, and stores the voltage detected by the A/D converter 302 when the power supply portion 100 is powered on; and a CPU 103 comparing the voltage stored in the memory with the voltage detected by the A/D converter 302 to detect an abnormal condition between the power supply portion 100 and the power receiving portion 300. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
