<p>PURPOSE:To input a revolving angle when a mouse device is rotated according to the distance between two shift amount detecting mechanisms as well as the shift amounts obtained from both detecting mechanisms. CONSTITUTION:Both X and Y axial shift amounts detected by a biaxial shift amount detector 11 and the X axial shift amount detected by a uniaxial shift amount detector 21 only for X axial direction are sent to a mouse connecting device 100 through output lines 12, 13 and 22 respectively. The data on these output lines have each bit number of image resolution of the detector 21. The revolving angle of a mouse device is calculated by the device 100 from those data received through the lines 12-22 and the distance (d) between both detectors 21 and 22. This calculation formula is shown at the right column when the data received through the lines 12-22 are assumed as Xi, Y1 and X2, respectively.</p> |
