CONDUCTOR POSITION INSPECTING DEVICE AND CONDUCTOR POSITION INSPECTING METHOD

摘要

A conductor position inspecting device capable of accurately detecting where an object of inspection is positioned in non-contact when the object of inspection is a conductor. An ac inspection signal is supplied from a feed unit (510) to a conductor to be inspected (520) to which an ac signal is applied, two sensor sheets (570, 580) are disposed almost in parallel in the vicinity of the conductor (520), detection signals from respective sensor sheets are subtracted from each other by a subtracter (550), a detection value from one sensor sheet is divided by the subtracted result by a divider (560) to normalize the detection value from one sensor sheet, and a relative detection signal value ratio from the both sensor sheets is detected to obtain a detection result corresponding to the distance between a sensor sheet and the conductor (520) as X.
