<p>PURPOSE:To improve a working efficiency by moving a leg placing body to arrange the detecting means of the rotating quantity of the sphere of a cursor into the internal part with the legs of an operator and rolling the sphere. CONSTITUTION:A sphere 13, a pair of driven rollers 14 and a rotating quantity detecting means 15 are stored into a slipper-shaped leg placing body 16, a coordinate input device 10 is constituted, a pair of rollers 14 is arranged so that it can contact with the sphere 13 partially protruded from the bottom of the leg placing body 16 and a shaft direction can be orthogonal and at one edge of both rollers 14, a rotating quantity detecting means 15 composed of an encoder, etc., is fitted. A switch 17 to specialize the position of the cursor is provided at an inserting recessed part 16a of the tip part of the leg placing body 16 and the switch 17 is operated with the toes of the leg of the operator.</p> |
