<p>PROBLEM TO BE SOLVED: To provide a data input device by which two operation bodies are used so as to enable executing the bi-directional inputs of mobile data and rotary data within two-dimensional data. SOLUTION: When one of rollers Xa and Xb rotating with an X-axis as a center is rotated, a picture is moved in the X-direction on a screen. When Xa and Xb are simultaneously rotated in a same direction, the picture is rotated around and X-axis. When the rollers Xa and Xb are rotated in a reverse direction, the picture is rotated around a Z-axis. Movement in the X-direction, rotation around the Y-axis and rotary data around the Z-axis data are inputted in the rollers Ya and Yb. The picture is moved in the Z-direction when the roller Za is rotated and, thus, three-dimensional movement and rotation data are inputted.</p> |
