摘要： A pointing device, such as a mouse, track ball or joystick, having a roller. The roller itself has either a plurality of slits or reflective strips for optical detection. A photoemitter and photodetector are positioned to detect rotation of the roller. Thus, the present invention eliminates the need for coupling to a separate optical encoder. The roller can be depressed to cause the actuation of a microswitch. In a preferred embodiment, the photoemitter and photodetector are aligned along a vertical axis, such that the position information is not affected by the vertical depressing of the roller.

摘要翻译：指示装置，例如鼠标，轨迹球或操纵杆，具有滚子。辊本身具有多个狭缝或用于光学检测的反射条。定位光电探测器和光电探测器以检测滚筒的旋转。因此，本发明消除了对单独的光学编码器的耦合的需要。可以压下滚筒以致微动开关的致动。在优选实施例中，光电检测器和光电检测器沿着垂直轴线排列，使得位置信息不受辊的垂直压下的影响。

摘要： A roller wheel structure having a simplified design. A support guide is connected to a lower housing for constraining and allowing movement of a roller wheel and roller support. In a preferred embodiment, the support guide is integrally formed with the lower housing, reducing the part count and enabling a more compact design. On one side of the wheel, the support guides connected to the lower housing support a spring around an axle connected to a support for the roller wheel. When the roller wheel is depressed by a user, the spring allows the roller support to depress until a micro-switch is activated. On a second side of the roller wheel, the roller support consists of a mechanism which slides up and down within the support guides connected to the lower housing when the user depresses the roller wheel. This side includes a spring biased against an open inside of the roller wheel. The spring is biased against an undulating surface on the inside perimeter of the wheel, providing a ratcheting effect when a user rotates the wheel.
摘要翻译：具有简化设计的滚轮结构。支撑引导件连接到下壳体，用于约束并允许滚轮和滚柱支撑件的移动。在优选实施例中，支撑引导件与下壳体整体形成，减少了零件数量并实现了更紧凑的设计。在轮的一侧，连接到下壳体的支撑引导件围绕连接到用于滚轮的支撑件的轴支撑弹簧。当滚轮被用户压下时，弹簧允许滚筒支撑件压下直到微动开关被激活。在滚轮的第二侧，滚子支架由当使用者按压滚轮时与连接到下壳体的支撑导向件之间上下滑动的机构构成。该侧面包括一个抵靠滚轮的打开内侧的弹簧。弹簧偏置在轮的内周上的起伏的表面上，当使用者旋转车轮时，弹簧提供棘轮效果。
