<p>PURPOSE:To attain a free input of various sizes of lines as if these lines were drawn by a pen with the pen holding pressure, by adding a pressure sensor to the tip of an input pen which is used for manual drawing of patterns. CONSTITUTION:An input pen 8 which is operated manually contains a pressure sensor 12 set at the inside of a pen top 11. The top 11 presses the sensor 12 with the pressing force of the pen 8, and the value of this force is delivered through a lead wire 13 in the form of the output of the sensor 12. This output is supplied to a microcomputer via an A/D converter 14 in the form of the digital value. When this input value is 0, no input is decided. When a fixed level of value is supplied, the points are turned on for input processing within a circle which defines the input value as its radius and the coordinate position given from a coordinate position detecting part 9 as its center respectively. In such a way, various sizes of lines can be fed freely as if these lines were drawn by a pen with the pen holding pressure.</p> |
