Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
Consult Fig. 3, it has shown according to the present invention a kind of luminous touch control pen for optical touch control apparatus (not shown) of preferred embodiment, comprises a penholder 2, nib element 3 and a luminescence unit 4.
With further reference to Fig. 4 and Fig. 5, nib element 3 comprises a solid transparent bar 31 that extends and be mounted to separably penholder 2 on a direction of principal axis of penholder 2, and a light focusing unit 32.
In the present embodiment, transparent bar 31 is made by transparent light guide material, for example acrylic acid.Transparent bar 31 has a first bar portion 311, the second bar portion 312 and a 3rd bar portion 313.The first bar portion 311 is for being arranged in penholder 2 and the openend 21 of close penholder 2; The second bar portion 312 connects the first bar portion 311, extends to outside penholder 2, and have a nib 314 for the touch-control surface 200 (seeing Fig. 3) of touch-control optical touch control apparatus via this openend 21; The 3rd bar portion 313 in contrast to the second bar portion 312, is connected to the first bar portion 311 on this direction of principal axis, and is thin compared with the first bar portion 311 and the second bar portion 312.The 3rd bar portion 313 is closely inserted into a mounting pipe 22 in penholder 2 (seeing Fig. 3).
Fig. 6 illustrates that first of nib element 3 ' changes, the second concentration structure 322 ' of light focusing unit 32 ' that what they were different from the nib element 3 of Fig. 5 is is a sheet metal, this sheet metal is coaxially embedded in the second bar portion 312 of transparent bar 31, and has one towards the outstanding convex reflective outer surface of the first bar portion 311 of transparent bar 31.In this preferred embodiment, the shape of this convex reflective outer surface of the second concentration structure 322 ' is conical, but not as limit.
Fig. 7 and Fig. 8 describe nib element 3 " second change; what they were different with the nib element 3 of Fig. 4 and Fig. 5 is light focusing unit 32 " the first concentration structure 321 " be the form with a ring-type albefaction reflection or refractive surface, this ring-type albefaction reflection or refractive surface be coaxial, and to be arranged at the first bar portion 311 of transparent bar 31 interior and form by the annular section in the first bar portion 311 of this transparent bar 31 of laser engraving.
In sum, because the second concentration structure 322,322 ' adjacent to nib 314, the light that luminescence unit 4 sends is collected by light focusing unit 32, then by the second concentration structure 322 or 322 ' reflection or refraction, to radiate away from the second bar portion 312, and then form a brightened dot that approaches very much nib 314, it can be covered by user's finger during use hardly.Therefore, when use, even if luminous touch control pen touches the touch-control surface 200 of optical touch control apparatus obliquely with nib 314, the sensed position that is relevant to nib 314 touch points in touch-control surface 200 can approach the position of nib 314 touch points in touch-control surface 200 very much, and wherein the sensed position in this touch-control surface 200 is that the light being radiated according to the second concentration structure 322 by optical touch control apparatus is determined.In this case, optical touch control apparatus can be oriented the touch point of nib body 13 in touch-control surface 200 more accurately.So in the time of luminous touch control pen of the present invention and optical touch control apparatus collocation use, optical touch control apparatus can be guaranteed in the accuracy of orienting a touch point.
Below only add and give explanation with regard to concrete constructed embodiment of the present invention, under without separated structure of the present invention and spirit, allly be skillful in those skilled in the art scholar, still can do all variations and modification, all this changes and is still considered as being encompassed in the following claim of this case with modifying.
