<p>PURPOSE:To obtain a hard copy of pictures with a simple operation by storing the coordinate data written on a plane panel into a picture memory after A/D conversion and then delivering the data to a printer interface. CONSTITUTION:The analog value corresponding to the coordinate data of X and Y is delivered to the position of a pen written on a front sheet 1 by a position sensor 2 consisting of a conductive sheet. The output signal of the analog value is stored in a picture memory 7 after an A/D conversion 4. Then an indication for start of hard copy is supplied to a microcomputer 6 through a switch part 8, and the contents of the memory 7 are delivered to a printer interface 9 from the computer 6. In such a way, a hard copy of pictures drawn on a panel is obtained by an external printer (not shown in the diagram).</p> |
