Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated:

Consult Fig. 3, a kind of luminous touch control pen that is used for the optical touch control apparatus (not shown) that it has shown according to the utility model preferred embodiment comprises a penholder 2, a nib element 3 and a luminescence unit 4.

Penholder 2 is made by transparent materials, and has an openend 21.

Further with reference to figure 4 and Fig. 5, nib element 3 comprises that one is extended and be mounted to separably the solid transparent bar 31 of penholder 2 and a light focusing unit 32 at a direction of principal axis of penholder 2.

In the present embodiment, transparent bar 31 is made by the transparent light guide material, for example acrylic acid.Transparent bar 31 has first a bar portion 311, second a bar portion 312 and the 3rd a bar portion 313.The first bar portion 311 is used for being arranged in the penholder 2 and the openend 21 of close penholder 2; The second bar portion 312 connects the first bar portion 311, extends to outside the penholder 2 via this openend 21, and has a nib 314 that is used for touch-control surface 200 (see figure 3)s of touch-control optical touch control apparatus; 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 than the first bar portion 311 and the second bar portion 312.The 3rd bar portion 313 closely is inserted into mounting pipe 22 in penholder 2 (see figure 3)s.

Light focusing unit 32 comprises first concentration structure 321, second concentration structure 322 and a reflection horizon 323.First concentration structure 321 coaxially is formed in the first bar portion 311 of transparent bar 31.In the present embodiment, this first concentration structure 321 is with the form of convex surface albefaction reflection or refractive surface roughly, this convex surface albefaction reflection or refractive surface coaxially are formed in the first bar portion 311, this convex surface albefaction reflection or refractive surface are outstanding towards the second bar portion 312 of this transparent bar 31, and form by the zone of the convex surface in the laser engraving first bar portion 311.In this preferred embodiment, the convex surface albefaction reflection of first concentration structure 321 or the shape of refractive surface are semispheres, but are not limited to this.Second concentration structure 322 coaxially is formed in the second bar portion 312 of this transparent bar 31, and is outstanding towards the first bar portion 311, and with the nib 314 adjacent settings of the second bar portion 312.In this preferred embodiment, second concentration structure 322 is with the form of convex surface albefaction reflection or refractive surface roughly, this convex surface albefaction reflection or refractive surface are outstanding towards this first bar portion 311, and form by the zone of the convex in the laser engraving second bar portion 312.In this preferred embodiment, the shape of this convex surface albefaction reflection or refractive surface is conical, but is not limited to this.Reflection horizon 323 parts are applied on the outside surface of the first bar portion 311 of transparent bar 31, so that the annular surface part 315 of the outside surface of the first bar portion 311 is exposed out, to such an extent as to first concentration structure 321 is visible via the annular surface part 315 of the outside surface of the first bar portion 311.Annular surface part 315 that it should be noted that the outside surface of the first bar portion 311 is polished in order to receive light from nib element 3 outsides effectively.

Luminescence unit 4, for example light emitting diode (LED) is fixed in the penholder 2, and can be luminous.The luminescence unit 4 radially adjoinings first bar portion 311, and the position is corresponding to the annular surface part 315 of the exposure of the outside surface of the first bar portion 311, and the light that is sent with electroluminescent unit 4 advances to the first bar portion 311 via the annular surface part 315 of the exposure of the outside surface of the first bar portion 311.Therefore, the light that luminescence unit 4 sends, wherein a part of light can be reflected towards second concentration structure 322 or reflection horizon 323 by first concentration structure 321 or reflect, and wherein the light of luminescence unit 4 emissions can advance to the first bar portion 311 via the annular surface part 315 of the brighten of the outside surface of the first bar portion 311.Then, from the light of first concentration structure 321 towards the reflection of second concentration structure 322 or refraction, and 323 reflection of layer that are reflected towards the light of second concentration structure 322 by 322 reflections of second concentration structure or refraction, in order to radiate away from the second bar portion 312.

Fig. 6 illustrates that first of nib element 3 ' changes, they are different with the nib element 3 of Fig. 5 is that second concentration structure 322 ' of light focusing unit 32 ' is a sheet metal, this sheet metal is coaxially embedded in the second bar portion 312 of transparent bar 31, and has a convex reflective outer surface of giving prominence to towards the first bar portion 311 of transparent bar 31.In this preferred embodiment, the shape of this convex reflective outer surface of 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 " 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 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 second concentration structure 322 or 322 ' reflection or refraction, in order to radiate away from the second bar portion 312, and then form one very near the brightened dot of nib 314, it can be covered by user's finger during use hardly.Therefore, during use, even the 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 on the touch-control surface 200 can be very near the position of nib 314 touch points on the touch-control surface 200, and wherein the sensed position on this touch-control surface 200 is determined by the light of optical touch control apparatus according to 322 radiation of second concentration structure.In this case, optical touch control apparatus can be oriented the touch point of nib body 13 on the touch-control surface 200 more accurately.So when the utility model luminous touch control pen 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 with regard to concrete constructed embodiment of the present utility model and give explanation, do not having under the structure of the present utility model of disobeying and the spirit, allly be skillful in those skilled in the art scholar, still can do all variations and modification, all this changes with modifying and still is considered as being encompassed in the following claim of this case.
