Abstract

PURPOSE:To input a turning angle when a mouse device is turned by calculating the turning angle of the mouse device main body from a moving amount detected by the two devices and the distance between the two devices. CONSTITUTION:A moving quantity detector 11 for two orthogonal axial directions and a moving quantity detector 21 for any direction are arranged on a straight line perpendicular to the one direction at a proper interval. Since a device 31 calculating a turning angle from the interval between the two devices and from the moving quantity detected by the two devices 11, 21 is provided, the turning angle in turning the mouse device 10 is inputted.

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a mouse device, and more particularly to a mouse device that allows input of a rotation angle in addition to the amount of movement in any direction on a plane.

Conventional techniques Mouse devices include mechanical mice, which rotate a ball attached to the bottom, and optical mice, which reflect light on a special board (mouse pad). There is an optical type.

Figure 3 (al, b) shows a conventional mouse device (mechanical mouse). Here, the same figure (al is the top surface of the mouse, tb) shows the bottom surface, and the bottom surface has ball bearings. 5 is attached, and two orthogonal rotating shafts receive the rotation of the ball bearing as the device moves, detect the amount of movement within a certain period of time from the amount of rotation, and output the result periodically. The output data includes the fourth

are placed at intervals of When the mouse device of FIG. 2 is rotated, the amounts of movement in the X-axis direction and Y-axis direction detected at 11 in FIG. 1 are sent to the device 100 through output lines 12 and 13, respectively. The rotation calculation mechanism 31 is 1
The amount of movement in the X-axis direction and Y-axis direction detected in 1, and 2I
The rotation angle is calculated from the amount of movement in the X-axis direction detected in , and is sent to the device C100 through the output line 32. The calculation formula is arccos ((xl-x2)/d), where xl yl x2 is the data sent through the output lines 12, 13, and 22, respectively. 12
．． The data above 13.22 indicates the number of bits of resolution of the detection mechanism, which in this embodiment is 8 bits. The data on 32 is also 8 bits here. The numbers in parentheses in the figure indicate the number of bits.

As described above, according to this embodiment, two orthogonal axes (X
