Abstract
A detecting device ( ) is provided to detect signals from a sensing mat ( ) including a plurality of sensing cells (R) electrically interconnected to each other in a matrix. Each sensing cell (R) is changeable in resistance with a change in a load to be applied. The detecting device ( ) comprises a detecting circuit (Rp) and voltage applying means ( ). The detecting circuit (Rp) detects a signal through a conversion of changes in the resistance to changes in voltage. When detecting a sensing cell (R ) connected to a specified line path ( ), the voltage applying means ( ) applies a particular voltage to the remaining line paths ( ). The particular voltage is for example voltage of which potential is the same as a voltage detected from the selected sensing cell (R ). Applying the particular voltage prevents current from bypassing the other line paths irrelevant to the detection.
