Touching (T) an arbitrary position 4 on a screen 1 displayed on a touch panel sets a plurality of screen areas A, B, C, and D into which the screen is divided using lines L 1 and L 2 which contain the position 4 and which traverse the touch panel screen 1, and a first quadrant, a second quadrant, a third quadrant, and a fourth quadrant which correspond to the screen areas are set. Touching (T) an arbitrary position 5 belonging to one C of the screen areas allows a character assigned to the corresponding quadrant (third quadrant) to be recognized. Releasing the character at the position 5 allows the character assigned to that quadrant to be confirmed.
