<p>The present invention discloses a mouse pen. The mouse pen includes a pen body set with several keystokes, a pen head pivot connected to pen body, a light unit, a lens, a reception sensor connected to the lens and a circuit board connected to the reception sensor. The end of the pen head sets a angular cut which parallel to the slide plane as used, the lens is located in the inner side of the angular cut the light emitted by the light unit irradiates the slide plane through the angular cut, whose image provided to the lens. The emitting position of this mouse pen and the position of the lens take a fixed mode and need not to adjust an angle of reflection, thus the producing time are reduced; the pen body can pivot connect to the pen head at ease, different users can use it in different modes according to their habit. Furthermore, the end of the pen head is designed to be bevel, which ensure the precision of the displacement position of the mouse pen.</p> |
