摘要： A coordinate input device including a housing having an opening, a ball received in the housing so as to be rotatable in any direction, the ball partially projecting through the opening, a pair of rotating shafts arranged so as to define a predetermined angle therebetween in the housing and adapted to be rotated in association with rotation of the ball, a spring for biasing the rotating shafts against the ball, a rotation detector for detecting a quantity of rotation of each of the rotating shafts, and a printed board mounted on the housing, the rotation detector being mounted on the printed board, whereby a cursor position or the like on a screen is controlled according to the rotation of the ball in any direction. The housing is provided with at least three supporting members for supporting the ball, at least three retaining portions for respectively receiving the supporting members from a side of the housing where the printed board is to be mounted and for respectively retaining the supporting members in contact with the ball, a shaft supporting portion for supporting each of the rotating shafts mounted into the housing from the printed board mounting side of the housing in such a manner that the rotating shafts are displaceable toward and away from the ball, and a spring retainer portion for retaining the spring mounted into the housing from the printed board mounting side of the housing.
