<p>PROBLEM TO BE SOLVED: To facilitate an input at a narrow place and to enable a simple and quick input. SOLUTION: The rotation of 2nd track ball 5 embedded at the position of left button is detected by a 2nd move detection part 6, and pressing is detected by a track ball pressing detection part 7. A signal excluding the signal of fine rotation component from a signal detected by the 2nd move detection part 6 through a filter part 9 and the rotation signal of 1st track ball 1 detected by a 1st move detection part 2 are synthesized by a move signal synthesizing part 10. The ratio of synthesization is set by a ratio setting switch 11. A click signal processing part 8 processes click signals detected by a mouse button pressing detection part 4 and the track ball pressing detection part 7.</p> |
