<p>PURPOSE:To form a means which detects the coordinate moving amount with use of a moving amount input means by calculating the absolute coordinates of a graphic after moving with the output of a moving amount input means, the output of a rotational angle arithmetic means, and the absolute coordinates of a pattern which is held by an absolute coordinate holding means. CONSTITUTION:When a moving amount input means 1 is turned on a plane, a rotational angle theta=arctan (DELTAY/DELTAX) is obtained by a rotational angle computing means 2 from the differences DELTAX and DELTAY of the X and Y directional moving amounts which are detected by two moving amount detecting means. A coordinate computing means 3 computes and outputs the absolute coordinates of a graphic after movement with the moving amount detected by two moving length detecting means, the rotational angle, and the absolute coordinates of a graphc before movement which is held by an absolute coordinate holding means 4. The absolute coordinates of the graphic after movement are shown by a display means 5 to update the contents held by the means 4. Thus it is possible to form a means which detects the coordinate moving amount with the use of the means 1.</p> |
