The small hole of the optical inducer of the traditional second-generation optical mouse used for receiving the images faces downwards, and corresponding light sources (including photoelectric diode and laser diode), optic lens and photosensitive holes are arranged at the lower part of the mouse; therefore, moving the whole mouse is a relatively convenient method for generating displacement of the mouse pointer; oppositely, the small hole of the optical inducer used for receiving the images faces upwards and corresponding light sources, optical lens and photosensitive holes (7) are arranged at the upper part of the mouse; matters on the upper surface of the photosensitive hole (7) can be moved so as to lead the mouse pointer to generate the displacement, while the moving signal transmitted by a photoelectric conversion device must be reset so as to comply with the integrated mouse of the invention.

传统的第二代光电鼠标的光学感应器接收图象的小孔是向下的，对应的光源(包括光电二极管，激光二极管)、光学透镜和感光孔都是在鼠标下部分，这样要想鼠标指针产生位移较方便的方法就是移动整个鼠标；相反，光学感应器接受图象的小孔向上，对应的光源、光学透镜和感光孔(7)在鼠标上部分，要使鼠标指针产生位移就只需移动附在感光孔(7)上面的物质，但必须重新设置光电转换装置传出的移动信号，以符合本发明。
