<p>PURPOSE:To provide an X-Y coordinate input device capable of omitting the use of an expensive bearing or rotational spindle energizing spring member and promoting cost reduction by adding a bearing function and a spring function to a synthetic resin-made sphere supporting member for mounting a sphere to be rotated. CONSTITUTION:Bearing wall parts 30, 31 having the 1st spindle inserting holes 30a, 31a and bearing arm parts 32, 33 extended from the wall parts 30, 31 respectively like cantilevers and having the 2nd spindle inserting holes 32a, 33a on their leading parts are unitedly molded on the sphere supporting member 25 for mounting the sphere 34 to be rotated so that the 1st rotational spindle 35 is pivoted by the wall part 30 and the arm part 32 and the 2nd rotational spindle 36 is pivoted by the wall part 31 and the arm part 33.</p> |
