<p>PURPOSE:To permanently match the original point of an overlay provided to a cover case or a housing by setting a reference point or an original point to a tablet, etc. and then shifting and storing these points with calculation. CONSTITUTION:A stylus or a cursor is abutted on the original point of an overlay, and detects the coordinate signal of the tablet, etc. set at the position corresponding to the original point of the overlay. Then the derived signal denoted as A is applied to an arithmetic circuit 3 and the inputs X-Data and Y-Data are outputted in the form of X'Data and Y'Data respectively via an output buffer 4. Then the low-order 7 bits of each output are applied to a memory 5 and data are written. Then a switch 1 is opened and changed over to the memory 5. Thus the information on the coordinate corrected by arithmetic can always be supplied.</p> |
