<p>PROBLEM TO BE SOLVED: To provide a coordinate information input device in which the rollers of X and Y axis detecting parts can be surely abutted on a ball in a simple configuration. SOLUTION: The respective detecting parts are composed of cylindrical rollers 15a and 15a abutted on the ball in X or Y direction, rotary shafts 14b and 15b for supporting these rollers, and detecting means 14c and 15c for detecting the rotations of these rotary shafts 14b and 15b. Concerning such a coordinate information input device, one end proximate mutually concerning the rotary shaft of each detecting part is supported so as to be moved horizontally, the other end is inserted into a bearing hole, and a spring 20 is provided so that one end 20b presses one end of the rotary shaft of one detecting part toward the side of the ball, and the other end 20c presses one end of the rotary shaft of the other detecting part toward the side of the ball.</p> |
