Embodiment
By describing technology contents of the present utility model, structural attitude in detail, being realized purpose and effect, describe in detail below in conjunction with embodiment and conjunction with figs..
See also Fig. 1, pen type optical mouse 100 of the present utility model places on the reference surface 200, comprises a tubular body 10, the body 10 inner circuit boards 20 of laying.Circuit board 20 1 sides assembling light-emitting component 30, opposite side assembling sensor chip 40, spectroscopic imaging element 50 is laid in the below.
Still see also Fig. 1, the utility model pen type optical mouse 100 also comprises an aperture 60, and sensor chip 40 is assembled in circuit board 20 homonymies and between sensor chip 40 and imaging len 52.
The use of the utility model pen type optical mouse 100 is as follows:
At first, light-emitting component 30 outside scattered beams, a part of light of ejaculation light guide section 511 guiding of leaded light prism 51 passes the light hole 13 of body 10.Then, reference surface 200 these light of reflection return light hole 13, and the light guide section 512 of injecting of leaded light prism 51 guides the light that returns from light hole 13 and makes this light enter imaging len 52.Then, imaging len 52 forms the image light signal with this convergence of rays, and transfers to sensor chip 40 through aperture 60.At last, the image sensor 41 sensing image light signals of sensor chip 40 and this image light signal is treated to the image electric signal, the image process unit of sensor chip 40 and then this image electric signal is treated to the cursor of mouse signal.
In above-mentioned use, the guiding of 51 pairs of light of leaded light prism of the utility model pen type optical mouse 100 is to adopt the mode of inner total reflection to carry out.When angle does not allow, can adopt leaded light prism 51 with one deck plated film, this layer plated film can be used to guide light.
