<p>PURPOSE:To prevent erroneous inputting operation securely by inhibiting coordinates of a pushed time from being inputted to an item input equipment, using pressure-sensitive conductive rubber, when an output signal from some circumferential item is detected. CONSTITUTION:When pressure-sensitive conductive rubber 2 of an item display surface is pushed, an X-axis line Xm is selected by a scanning circuit S. Then, a detecting circuit D detects the existence of outputs of Y-axis lines Yn-1 Yn and Yn+1. Similarly, the scanning circuit S detects X-axis lines Xm-1 and Xm+1, and the detecting circuit D detect outputs of the Y-axis lines Yn-1, Yn and Yn+1. As a result, when there is a detection signal only at the Y-axis line Ym with the X-asis line Xm, it is judged that the rubber is pushed with a push element, thereby outputting the coordinates. Therefore, even if the rubber is pushed in error with the palm of the hand, an error signal is outputted to prevent erroneous inputting.</p> |
