Abstract

PURPOSE: To continuously scroll an image which is currently displayed in a selected direction without restrictions on the scrolling direction by providing a scrolling direction specifying means and a scrolling means. CONSTITUTION: This device is equipped with a command program 31 for scrolling direction specification which specifies a direction indicated by an operator as a scrolling direction when the operator indicates the scrolling direction and a command program 32 for scrolling which scrolls a CAD diagram displayed on a display device 18 at a specific speed in the scrolling direction specified by the program 31. Then the command program 32 is executed to scrolls the currently displayed CAD diagram at the constant speed in the selected scrolling direction. Thus, there is no restrictions on the scrolling direction and the drawing is scrolled in free directions, so flexibility is given to the selection of the scrolling direction.
