INPUT DEVICE

PROBLEM TO BE SOLVED: To provide an input device structured to be fit to enlargement for simplifying the structure and for reducing costs. SOLUTION: An input device 10 includes a substrate 20 having a plane 22 at the upper side of a vertical direction Z; and a rolling part 30 equipped with a cross-sectional circular arc section 31a formed so as to be rollable to the substrate 20, and configured so that a center of gravity 30b is present at the lower side of the vertical direction Z of a center 31c of the circular arc section 31a, and the positive position of the input device 10 is set in such a state that the center 31c and the center of gravity 30b of the circular arc section 31a are present on the same vertical line; and a magnetic sensor 23 for detecting the scale of an inclination from the positive position of the rolling part 30, and for outputting a detection signal to a game machine 1.
