X-Y direction input device having changeable orientation of input axes and switch activation

摘要

An X-Y direction input device includes a ball, a switchboard carrying push switches, first and second follower rollers rotated by the ball having axes perpendicular to each other, and rotation detecting means which all are enveloped by an outer shell. The push switches are activated by switch activating members exposed on the outer surface of the outer shell. The axes of the first and second follower rollers may be rotated by a desired angle with respect to an orientation of the outer shell.
