<p>PURPOSE:To easily decide the timing for input of the coordinates and at the same time to reduce the processing load to the input of the coordinates by providing a means to check whether or not the coordinate information obtained continuously from a coordinate input means are kept within a fixed time and a fixed distance. CONSTITUTION:The identification information showing whether the next coordinate information is kept or not within a fixed time and a fixed distance to the first coordinate information is added to the coordinate information 11 together with the identification information 14 or 15 showing a fact that the same coordinates are continuously pointed. In other words, the information 11 shows the presence of the continuous coordinates where the input time interval is fixed for each coordinate as long as an output signal 21 is kept to '1'. Meanwhile a distance computing circuit 6 receives two continuous pieces of information 11 and calculates the distance between these two points of information 11 to decide whether this distance is kept within a fixed value or not. Thus it is possible to decide the timing for input of the coordinates and also to reduce the processing load to the input of the coordinates.</p> |
