A numerical value input device is provided that makes it possible to suitably input numerical values using a GUI. The device is equipped with: an image data storage unit (11) that stores coordinate plane image data having first and second axes; an image-generating unit (12) that generates point drawing image data of point drawings indicating position on the coordinate plane and drawing image data to a larger scale of larger-scale drawings obtained by magnifying a region including the position of a point drawing; an image display unit (13) that displays coordinate plane image data, point drawing image data and larger-scale drawing image data; an instruction receiving unit (14) that receives instructions specifying the position of a point drawing that is displayed; a numerical value acquisition unit (15) that acquires first and second numerical values of first and second axes corresponding to the position of a point drawing on the coordinate plane; and an output unit (16) that outputs first and second numerical values. This image generating unit (12) generates point drawing image data corresponding to a position specified by the instruction that is received. |
