<p>PURPOSE:To draw the graphics on a screen in the sense to handle a head and a writing tool of a free parallel ruler device by shift and rotate a rectangular scale line via one of two cursor devices and pointing a coordinate position via the other cursor device. CONSTITUTION:A cursor device 54 is moved in the XY direction on a table plane with no push of a mouse key of the device 54. Thus the output change values of x and y of the device 54 are directly converted into the parallel shifts of a rectangular scale line 64 and displayed. When the device 54 is moved in the XY direction on the table plane with push of the mouse key, those output change values are converted into the angles. On the other hand, when a point is pointed on a digitizer 4 with the tip of a cursor device 6, the coordinate signal of this pointed point is inputted. Thus the lines 64 are equivalent to the rectangular scales, i.e., a pair of right rulers provided to the head of a free parallel ruler device. While the device 6 is equivalent to a writing tool.</p> |
