Document Type and Number:
Japanese Patent JP6816446
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a disconnection detector which has a simple structure.SOLUTION: A disconnection detector 20 includes a detection circuit 13 which turns on or turns off a second ground switch 26 while fixing a first detection switch 21 in an on-state and fixing a second detection switch 22 and a first ground switch 25 in an off-state and determines whether there is a disconnection in a first detection line 15 according to whether the capacitance change amount detected by the turning-on or turning-off corresponds to a preset value.SELECTED DRAWING: Figure 3
