To provide an information processor having a pressure sensitive information conversion function which speedily converts designated data and outputs it through the use of the pressure sensitive means of a pressure sensitive sensor.

The information processor has a pressure sensitive coordinate input device 11 which has a pressure sensitive sensor that can detect the pressure degree of not less than two stages, and instructs a coordinate on a display device 15 and a data conversion part 14 converting designated data on the display device 15 in accordance with the pressure degree detected by the pressure sensitive sensor. Conversion data is displayed on a coordinate position on the display device 15, which is instructed by the pressure sensitive coordinate input device 11.
