Abstract

PURPOSE:To obtain a 3-dimensional coordinate input device by assembling a mercury switch and a pushbutton switch to a coordinate input device such as a Mouse and changing a coordinate to be inputted depending on the state and career of the switch. CONSTITUTION:The mercury switch 10 is turned on when the coordinate input device main body 7 is tilted from a horizontal plane by >=35 deg. and turned off when the main body is not tilted. An axial direction mobile detector 11 detects a movement of the main body 7 in parallel with a reference plane and consists of wheels rolling on the reference plane and a shaft encoder connected to the wheels. One axial direction movement detector 11 detects the movement of the main body to a specific axial direction. The movement of the main body 7 in parallel with the reference plane is detected by arranging the axial direction movement detector 11 at a right angle. A signal from the pushbutton switch 12, the mercury switch 10 and the axial direction movement detector 11 is transmitted to an eletronic computer through a cable 13.
