<p>PURPOSE:To set a position exactly, by displaying a linear distance between a position before movement and a position after movement of a reference point. CONSTITUTION:When a start key 12 of a cursor moving operation device 4A is set, a data for indicating a position A (X1, Y1) is read in a CPU. Subsequently, a cursor K is moved to a position B (X2, Y2) by operating a cursor moving key 6, and when a stop key 13 is set, a data of a position of the cursor K is read in the CPU. Subsequently, a moving extent of a position extending from A to B of the cursor K is calculated in accordance with x=X2-X1 and y=Y2-Y1, and also a linear distance Z=(x<2>+y<2>)<1/2> is calculated. Accordingly, a linear distance between a position before movement and a position after movement of the cursor K is displayed, and the cursor is set exactly.</p> |
