PROBLEM TO BE SOLVED: To move continuously a display part of a digital map at an optional speed by answering a moving amount of a pointer placed on the display part to the moving speed of the display part of the digital map with in a display screen. SOLUTION: A mouse 6 is made move from a state of a solid line to the state of a dotted line in the direction of e.g. desired D while depressing the left button 6b of the mouse 6 with a user's finger. That is, drag operation is performed with the mouse 6. Thus, the ball 6d of the mouse 6 arrives at an end point EP from a starting point STP. A distance LX related to the desired direction D from the starting point STP to the end point EP is equivalent to a length of an arrow part of a pointer. When the length LX related to the desired direction D is longer, the moving speed of the display part of the digital map in the direction of the arrow part is increased, and inversely, when the length LX is shorter, the speed of the display part of the digital map related to the direction of the arrow part of the pointer is decreased.
