Abstract
The utility model discloses an infrared electronic whiteboard marker, which comprises a marker stem (4) and an infrared emitting diode (3) forming a marker head. The infrared electronic whiteboard marker is characterized in that a transparent plastic cap (2) is sleeved outside the infrared emitting diode (3), and a metal ball (1) on the head of the transparent plastic cap (2) is disposed inside the transparent plastic cap (2). The infrared electronic whiteboard marker is high in precision and not limited by a reflection surface anymore.
Description
Technical field
The utility model relates to a kind of infrared exoelectron blank pen.
Background technology
Existing interactive electric whiteboard mainly contains infrared type, pressure-sensitive and electromagnetic type interactive electronic white board and resistive touch screen by technical classification, and wherein infrared receiving type electronic whiteboard enjoys educational circles' favor because of it is cheap.Its principle of work is: infrared filter camera is aimed at blank and is monitored, because the cause of filter sheet, it can only monitor the infrared ray luminous point of respective wavelength, when infrared (blank) pen is clicked on blank, the infrarede emitting diode of nib can send infrared ray, and infrared ray is received by infrared filter camera after the reflection of blank plate face, and data are passed to computer, after process analysis, convert the coordinate figure of cursor to, finish positioning action.Based on this principle, infrared (blank) pen can not be aimed at infrared camera in real time (because of operating on blank, nib can only be back to camera, and nib is exactly an infrarede emitting diode), locate so can only put by infrared light reflection, reflection spot where, and computer cursor and pointer will point to the there.But because of each operator's the pen of holding is accustomed to different, the contact angle of pen and blank is also just different, make and have in various degree error distance between ultrared reflection spot and the nib, at this moment the operator will feel that the position of nib and cursor pointer is inconsistent, out of true makes that operation is not smooth, not handy.In addition, continuous downward modulation along with large scale liquid crystal TV price, projector is replaced with big liquid crystal in increasing classroom, like this infrared exoelectron blank based on above principle just can not use, because the infrared ray of infrared (blank) pen can penetrate LCD screen, and can not reflect, even if the light that reflects is also very faint, be not enough to drive camera, infrared absorption filter ytterbium camera has just become blind person like this, can't play positioning action.Therefore, designing a kind of infrared exoelectron blank pen that can overcome above drawback, is the present technical issues that need to address.New infrared exoelectron blank pen is greatly improved on precision, and simultaneously, infrared pen no longer is subjected to the constraint of reflecting surface, can operate on any material (on the glass surface can).
Summary of the invention
Technical problem to be solved in the utility model provides a kind of precision height, no longer is subjected to the infrared exoelectron blank pen of the constraint of reflecting surface.
The technical scheme in the invention for solving the technical problem is:
A kind of infrared exoelectron blank pen comprises penholder and constitutes the infrarede emitting diode of nib, in the outer cover of infrarede emitting diode the transparent plastic cap is housed, and is provided with Metal Ball in the transparent plastic cap, and Metal Ball is at the head of transparent plastic cap.Described Metal Ball is aluminium ball, aluminium alloy ball, aldary ball or stainless steel ball.
Principle of work is: the pen head part of existing infrared blank pen is made up of an infrarede emitting diode, we put a transparent pipe box for original infrarede emitting diode now, be bumped into an aluminium ball (or other Metal Ball) in the pipe box, the diameter of aluminium ball (or other Metal Ball) and the external diameter of infrarede emitting diode are similar, like this, when infrared the infrarede emitting diode that is pressed is luminous, on the infrared ray meeting direct irradiation aluminium ball (or other Metal Ball) in front, and the ultrared reflectivity of metal pair is best, reflection by it is received by infrared receiving device again, the light that not only receives is strong, and not having large-area hot spot, the location is also just corresponding accurate.
Compared with prior art, the utlity model has following advantage:
1, with low cost, stability is strong; 2, improve the application surface of infrared exoelectron blank,,, go in liquid crystal or the line holographic projections so no longer need the cooperation of operation panel face because nib has carried the reflection material; 3, the location is more accurate, and aluminium ball (or other Metal Ball) reflects infrared light by pen head part makes Infrared more concentrated brighter, and it is higher to receive sensitivity, and it is more accurate to locate; 4, be convenient to promote,, do not change the circuit and the mechanical hook-up of original blank pen, so convenient the popularization carried out because this remodeling method is simply effective.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in the figure, a kind of infrared exoelectron blank pen comprises penholder 4 and constitutes the infrarede emitting diode 3 of nib, in the outer cover of light emitting diode 3 transparent plastic cap 2 is housed, and is provided with Metal Ball 1 in transparent plastic cap 2, and Metal Ball 1 is at the head of transparent plastic cap 2.
Described Metal Ball 1 is aluminium ball, aluminium alloy ball, aldary ball or stainless steel ball.
Claims (2)
1. infrared exoelectron blank pen, comprise penholder (4) and constitute written infrarede emitting diode (3), it is characterized in that: the outer cover at infrarede emitting diode (3) is equipped with transparent plastic cap (2), be provided with Metal Ball (1) in transparent plastic cap (2), Metal Ball (1) is at the head of transparent plastic cap (2).
2. a kind of infrared exoelectron blank pen according to claim 1 is characterized in that: described Metal Ball (1) is aluminium ball, aluminium alloy ball, aldary ball or stainless steel ball.
