<p>PURPOSE:To attain the direct use of a received coordinate value without converting it into the desired scaling each time by inputting the coordinate value in an optional magnification ratio which is designated from outside. CONSTITUTION:The position information supplied from a detection panel 1 is outputted through a coordinate value detecting part 2 in the form of the digital value proper to both X and Y coordinates. A converting part 3 multiplies the X and Y coordinates by a prescribed magnification ratio and outputs this value of multiplication to outside through an interface part 5. In this case, the input proper coordinate value is converted into the analog value by a D/A converting part 10 at the part 3, then amplified properly at an amplifying part 20. This amplified coordinate value is attenuated at an attenuating part 30 in accordance with the contents of a memory part 4 then converted again into the digital value through an A/D converting part 40. Here the gain of the part 20 is set to 20dB, and otherwise the part 30 can designate the degree of attenuation every 1dB. Furthermore, the value 0-40 can be set at the part 4. The output of a coordinate value input device can be varied in 41 kinds of magnification ratios including 1/10-10 times as much as the proper detected coordinate value.</p> |
