<p>PURPOSE:To discriminate a coordinate data obtained by the pressing operations which are discontinuous in terms of time and to deliver a coordinate data in faithfully response to the shift of the pressure point, by extracting successively the discontinuity of a coordinate data train due to the change of the pressing intensity of the resistance film and then comparing a deviation between the data and the prescribed value. CONSTITUTION:The potential levels detected with the continuous shift of the pressure points of the resistance films 1 and 2 are successively extracted by an A/D converter ADC. A coordinate data is applied to an arithmetic processor CPU of a processor unit PU to obtain a deviation between the coordinate data. The discontinuity of a coordinate data train due to the discontinuous pressing time of the films 1 and 2 is monitored by a transistor TRQ5, an FF2, etc. Then the coordinate data obtaned by the discontinuous pressing operation of the films 1 and 2 is discriminated by the unit PU. Thus the discontinuity of the coordinate data due to a change of the pressing intensity is avoided to deliver a locus coordinate data in faithfully response to the shift of the pressure point.</p> |
