PURPOSE: To prevent artificial connection error by automatically generating an inter-sheet connector so as to connection relation even after movement when the moving destination of a graphic, which is separated and selected for the movement according to an input from an operating terminal, is the other sheet.

CONSTITUTION: On an operating terminal 5, a moving object selecting means 1 selects a graphic or a graphic group as the moving object in an interactive form and a moving destination designating means 2 designates the moving destination in the interactive form while drugging the graphic or the graphic group selected by the moving object selecting means 1. An inter-sheet connector generating means 3 automatically generates the inter-sheet connector in each sheet so as to keep the original connection relation when the moving destination designated by the moving destination designating means 2 is different from the sheet where the moving object exists, and a moving object arranging means 4 arranges the graphic or the graphic group selected by the moving object selecting means 1 to the moving destination designated by the moving destination designating means 2 and connects it to the inter-sheet connector generated by the inter-sheet connector generating means 3. Thus, connection error can be eliminated.
