<P>PROBLEM TO BE SOLVED: To provide a method for detecting distance information between two points on a resistive film touch panel. <P>SOLUTION: At step S9, in a state that both ends of a first resistive film in an X-axis direction are short-circuited and a predetermined constant current is supplied to both ends of a second resistive film in a Y-axis direction, a potential V(X) is measured at the both ends of the first resistive film in the X-axis direction. At step S10, in a state that both ends of the second resistive film in the Y-axis direction are short-circuited and a predetermined constant current is supplied to the both ends of the first resistive film in the X-axis direction, a potential V(Y) is measured at the both ends of the second resistive film in the Y-axis direction. When the first resistive film comes into contact with the second resistive film at the two points, a potential V(X) has a value corresponding to the distance between the two points in the X-axis direction, and a potential V(Y) has a value corresponding to the distance in the Y-axis direction. At steps S11 through S19, a piece of distance alteration information between the two points when the first resistive film comes into contact with the second resistive film is obtained based on the potential V(X) and the potential V(Y). <P>COPYRIGHT: (C)2012,JPO&INPIT |
