    • A computer input device is comprised of an upper shell a center body and a lower shell, wherein the upper shell is operated so to slide along x axle and y axle, thus the object of controlling the movement and positioning of a cursor on a computer screen is achieved. A structure for detecting the displacements on the direction of x axle and on the direction of y axle is arranged inside the computer input device, and an x axle photoelectric set and a y axle photoelectric set for detecting the action of optic grid piece is also arranged inside the computer input device, and the structure for detecting the displacements on the direction of x axle and on the direction of the y axle is arranged on the same plane by a design of bracing wires, thus the width of the whole structure is became thinner, and volume of the computer input device is reduced so that the computer input device of the present invention may be proper installed on the notebook type personal computer.
    • 计算机输入装置包括上壳体,中心体和下壳体,其中上壳体沿x轴和y轴运动,从而控制光标在计算机屏幕上的运动和定位的目的 已完成。 用于检测x轴方向和y轴方向上的位移的结构被布置在计算机输入装置的内部,并且还布置有用于检测光栅板的作用的x轴光电装置和轴轴光电组件 计算机输入装置和用于检测x轴方向和y轴方向上的位移的结构通过支撑线的设计布置在同一平面上,因此整个结构的宽度变薄, 并且计算机输入装置的体积减小,使得本发明的计算机输入装置可以适当地安装在笔记本型个人计算机上。

    • A cursor control device for controlling the movement and positioning of a cursor on a computer includes a finger controllable member formed on the cursor positioning device. The cursor on the display is controllable either in X-axis or Y-axis direction by means of sliding the finger controllable member on the device. The cursor positioning device includes a displacement detecting structure for detecting the movement of the finger controllable member, and photo encoder detectors for detecting the operating situation of the X-axis and Y-axis photo encoders which are arranged in 90 degrees phase deference in space. In such an arrangement, the displacement of the finger controllable member in X-axis and Y-axis direction may be detected as coordinate date. The detected coordinate data is transmitted to a control circuit for further processes and then sent to a computer device.
    • 用于控制光标在计算机上的移动和定位的光标控制装置包括形成在光标定位装置上的手指可控部件。 显示器上的光标可以通过在设备上滑动手指可控元件在X轴或Y轴方向上控制。 光标定位装置包括用于检测手指可控构件的移动的位移检测结构,以及用于检测在空间上以90度相位排列的X轴和Y轴光编码器的操作状态的光电编码器检测器。 在这种布置中,手指可控构件在X轴和Y轴方向上的位移可以被检测为坐标日。 检测到的坐标数据被发送到控制电路以进一步处理,然后发送到计算机设备。
