Creation instructions (8)) and the fourth positioning element 2 4 6 can install the circuit board 2 & in the housing 33 and make the trackball 211 It can be exposed to the outside of the housing 33 by the track ball groove 31. In this way, when using the input device 30, the user can also easily rotate the track ball 2 11 to control the track ball 2 11 Cursor of the display. i ~ In this embodiment, please refer to FIG. 4 again. The input device 30 may be provided with a control circuit. The control circuit and the host may be connected to each other, and the identification element 242 (such as the third (Shown in the figure), the calculated displacement data can be transmitted to the control circuit, and the displacement data can be transmitted to the host through the control circuit. In this way, the optical trackball structure can share the transmission line with the input device. (Or wireless transmission) for the transmission of data. The above description is only for the original creation. The structural features of the work are not limited to the field of creation, and the scope of the patents in this case can be easily considered. As one of the best specific embodiments, however, any person skilled in the art who is changing or modifying can also cover
