Embodiment
Embodiment of the present utility model is illustrated by particular specific embodiment below, those skilled in the art can be by this
Content disclosed by specification understands other advantages and effect of the present utility model easily.
It should be clear that structure depicted in this specification accompanying drawing, ratio, size etc., only coordinating disclosed in specification
Content, for those skilled in the art understand and read, be not limited to the enforceable qualifications of the utility model,
Therefore do not have technical essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size, do not influenceing this reality
With under new the effect of can be generated and the purpose that can reach, all should still falling in the technology contents institute disclosed in the utility model
In the range of covering.It is meanwhile cited such as " on ", " under ", "left", "right", " centre " and " one " etc. in this specification
Term, understanding for narration is merely convenient to, and is not used to limit the enforceable scope of the utility model, the change of its relativeness
Or adjustment, in the case where changing technology contents without essence, when being also considered as the enforceable category of the utility model.
Referring first to Fig. 8, there is shown with the light guide 3 of two kinds of structures in the prior art.The main body of two kinds of light guides 3 is shaft-like
Printing opacity main body, the optocoupler for being optically coupled into face 33 and 34, positive exiting surface 35 and the back side that the printing opacity main body includes positioned at both ends go out
Face.A kind of optocoupler is appeared 4 to be prism array face, and another optocoupler is appeared the 5 diffusing reflection faces formed for rough surface.Using
When, the light of light source (not shown) enters light guide 3 from the face that is optically coupled into 33 and/or 34, and light is propagated in light guide 3, gone out through optocoupler
Projected after the reflection of face from exiting surface 35.But both structures, which all have light, directly to escape from light guide 3 from the back side of light guide 3
Problem, causing the utilization ratio of light reduces.And in the case where optocoupler appears 4 as prism array face, following ask also be present
