Abstract

PURPOSE:To prevent an erroneous output of a data, by sending out only one coordinate position data, even in case when an instructing operation of once to an operation panel extends over plural retrieval scanings. CONSTITUTION:Detecting electrodes Y1-Y4 and X1-X4 are selected successively by one piece each by an analog multiplexer 12 and are connected to a parallel resonance circuit. The selecting operation of this detecting electrode is repeated successively and automatically by a three bit binary counter 18. In case when one detecting electrode selected by the multiplexer 12 is in a touch state, an output pulse is sent out through a detecting circuit, a comparator 14, a smoothing circuit 15 and a differentiating circuit 16. By an output C of the binary counter 18, a latching pulse is selected by AND circuits 19Y, 19X, and address data, namely, outputs A, B of the counter 18 are inputted to latching circuits 20Y, 20X. A data sending-out circuit 21 puts in order in terms of the time an address of the X detecting electrode retrieved in one scan of retrieval, and a coordinate position data of the Y detecting electrode, and sends them out simultaneously.

When one detection electrode selected by the analog multiplexer 12 and connected to the detection circuit is in the touch state, the amplitude of the sine wave output waveform (■) from the detection circuit decreases, and the amplitude of the sine wave output waveform (■) from the detection circuit decreases. The level of the output waveform @ becomes the ``L'' level. Therefore, since the waveform ■ is input to the smoothing circuit 15 through the comparator 14, the output waveform oFi detection circuit of the smoothing circuit 15 is connected to the detection electrode in the touch state. Changes from 7'H Lebel to ゞL Lebel. When the output waveform O from the smoothing circuit 15 is inverted and inputted to the differentiating circuit 16, an output/curse O is sent out from the differentiating circuit 16. In this way, the differentiation circuit 16
The state of the pinarikakunta 18 at that time is determined by the output pulse O obtained through the latch circuits 20Y and 20X.
