Device for detecting signals of sensing cells interconnected in a matrix |
摘要 |
<p>A detecting device (1) is provided to detect signals from a sensing mat (2) 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 (1) comprises a detecting circuit (Rp) and voltage applying means (5). The detecting circuit (Rp) detects a signal through a conversion of changes in the resistance to changes in voltage. When detecting a sensing cell (R11) connected to a specified line path (2a), the voltage applying means (5) applies a particular voltage to the remaining line paths (2a). The particular voltage is for example voltage of which potential is the same as a voltage detected from the selected sensing cell (R11). Applying the particular voltage prevents current from bypassing the other line paths irrelevant to the detection. <IMAGE></p> |
