    摘要： In the coordinate detection of resistive film system, detection of the coordinates of simultaneously designated two points is made possible. On a touch panel composed of two conductive films, whether input is made in a point or simultaneously at two points is judged by a current monitor. Simultaneous inputs at two points decrease the apparent resistance of the conductive film, and can be detected by an increase in the current. If the input of a point is identified, the coordinate data of the input point are retained as latest coordinate data in a RAM. If simultaneous inputs at two points are identified, coordinate data are obtained from the coordinate data retained in the RAM and from the potentials in the x and y directions, obtained from two conductive films constituting a touch panel, through amplifiers, and are outputted, together with the coordinate data retained in the RAM, as the coordinate data of the two points.

    摘要： Continuity of coordinates between areas of a coordinate input surface which is divided into a plurality of areas is maintained. In inputting "A, B, C" on a coordinate input plate, when an input operation is started from an initial point (a), area 1 is determined as an input area, and vibration delay times are measured by using sensors (6a, 6b, 6d), thereby calculating a coordinate value. When the input operation is continued up to a terminal point (a'), the input point shifts to area 3. However, vibrations are detected by using the same sensors (6a, 6b, 6d) to calculate a coordinate value as long as the input operation is continuously performed. With this operation, since sensors are not changed for the respective areas, discontinuity of lines at the boundaries between the areas can be prevented.
