A control unit stores the X-coordinate of a finger when X-coordinates of a character string CS2 and a character string CS1 accord. When the finger is moved, the control unit calculates a difference between the stored X-coordinate and an X-coordinate of the finger after movement, and a movement amount of the character string CS2 is made small with respect to a movement amount of the finger until the calculated difference becomes a predetermined difference. When the calculated difference becomes the predetermined difference or more, the control unit sets a display position of the character string CS2 to a position of the finger.
