产品描述-
2D机械滾轮鼠标，com口连接台式计算机，适用于精密数控机床设备及医学设备。
工作原理
当你拖动鼠标时，带动滚球转动，滚球又带动辊柱转动，装在辊柱端部的光栅信号传感器产生的光电脉冲信号反映出鼠标器在垂直和水平方向的位移变化，再通过电脑程序的处理和转换来控制屏幕上光标箭头的移动。它的底部没有相互垂直的片状圆轮，而是改用一个可四向滚动的胶质小球。这个小球在滚动时会带动一对转轴转动（分别为X转轴、Y转轴），在转轴的末端都有一个圆形的译码轮，译码轮上附有金属导电片与电刷直接接触。当转轴转动时，这些金属导电片与电刷就会依次接触，出现“接通”或“断开”两种形态，前者对应二进制数“1”、后者对应二进制数“0”。接下来，这些二进制信号被送交鼠标内部的专用芯片作解析处理并产生对应的坐标变化信号。只要鼠标在平面上移动，小球就会带动转轴转动，进而使译码轮的通断情况发生变化，产生一组组不同的坐标偏移量，反应到屏幕上，就是光标可随着鼠标的移动而移动。
Computer Mice
Every computer user can hopefully identify their mouse and the importance it plays in the daily operation of their computer. Mice are nothing new and for the most part are nothing overly complex, but the average user may not be familiar with all of the options and technologies that may go into these little devices. This Tech Tip will take a look at some of the features of mice that people may take for granted, or may otherwise be unaware of.
Tracking Technologies
Mechanical mice- Mechanical mice were the first ones used on computers, and can still be found for sale, despite the advances of tracking technologies. These mice feature a hard ball on the underside that rolls as the mouse is moved, and rollers inside the mouse allow the physical motion to be translated to the pointer on the screen. Some “ball mice” are a bit more advanced and replace the internal rollers with optical sensors, but the same principle applies.
Mechanical mice require occasional maintenance to keep the ball and rollers free of lint and other debris, and with numerous moving parts there is always a potential for problems. The use of a mouse pad is recommended for these mice as they not only provide a clean surface to work on, but also provide the needed resistance for the ball to roll smoothly.
The precision of mechanical mice is not particularly good, and although they may be fine for typical desktop work, they were never quite up to the task of detailed graphics work or serious game playing.
