PURPOSE: To ensure the higher facilitation in a visual way for an address production system than the use of a user interface by shifting the address icons via a mouse to produce an address list.

CONSTITUTION: An icon 19 showing an address to be registered into an address list is selected out of a window 17 for the address list via a mouse 9 and then the mouse 9 is moved. Thus an icon shift device 6 detects the moving direction and the moving distance of the mouse 9 and shifts the icon 19. Then the icon 19 showing the selected address is moved into a window 18 of the address list. In such a way, the icon 19 is selected out of the window 17 and moved into the window 18 by the mouse 9. Thus an address list is easily produced.
