Abstract
Provided is a photoelectric pressure induction pen, including an illuminator, a pervious cover and a neb located on the pervious cover, characterized by further including a pressure sensing element for sensing the neb pressure, and a signal processing module connecting with the pressure sensing element, which may adopt a pressure frequency conversion incuctor or a pressure sensing resistor. The photoelectric pressure induction pen of the utility model uses the pressure sensing element for processing the presssure signals when writing, to make the writing script changing with the writing pressure, which makes the final displaying effect is like the handwriting authentic work to provide favorable handwriting input effect.
Description
[technical field]
The utility model is about a kind of photoelectric pen, refers to a kind of photoelectricity pressure induction pen that can realize display effect as the hand-written authentic work especially.
[background technology]
Existing photoelectric pen generally includes light-emitting device and is installed on the diffuser that the light-emitting device front is used to protect light-emitting device, and the light that light-emitting device sends shines the track that generation is write on screen by diffuser.Owing to write the influence of angle and Flame Image Process precision, existing photoelectric pen only can be judged the position of writing a little by corresponding software and the accurate size of perception point, thereby the effect of writing is that the same single stroke of thousand people is linear.
Therefore, prior art is improved, a kind of improvement input effect is provided, can realize that on display screen the photoelectricity pressure induction pen of display effect is real in necessary as the hand-written authentic work.
[summary of the invention]
The purpose of this utility model is to provide a kind of improvement input effect, can realize the photoelectricity pressure induction pen of display effect as the hand-written authentic work on display screen.
To achieve these goals, the utility model adopts following technical scheme:
A kind of photoelectricity pressure induction pen is provided, and it comprises illuminator, diffuser and is positioned at nib on the diffuser, it is characterized in that it further comprises the pressure responsive element that can respond to this pen point pressure, and the signal processing module that is connected with pressure responsive element.This pressure responsive element adopts pressure variable frequency induction device.
This pressure variable frequency induction device adopts quartzy frequency conversion material, is used for responding to the variation of pen point pressure when writing, and the pressure variation is converted into frequency change.This signal processing module comprises signal reception/converting unit, signal encoding unit, wireless signal transmitting element and controller.This signal processing module receives aforementioned frequency change and the mode of its coding back with wireless signal is sent.
This nib is made by the less or wear-resisting flexible material of friction factor, can prevent to scratch screen and write good hand touch.Nib and illuminator are concentricity, and axle is provided with.The light of optical element with reflection or the emission of refraction illuminator is set around the illuminator, makes light walk around the place ahead that nib shines nib.
The utility model also can adopt following another kind of technical scheme:
A kind of photoelectricity pressure induction pen is provided, and it comprises nib, is positioned at the illuminator of nib one side, it is characterized in that, it further comprises the pressure responsive element that can respond to this pen point pressure, and the signal processing module that is connected with pressure responsive element.This pressure responsive element adopts the quick resistance of pressure.
This signal processing module comprises signal reception/converting unit, signal encoding unit, wireless signal transmitting element and controller.The quick resistance of pressure links to each other with nib, pen point pressure is changed being converted into resistance change.Signal processing module receives and handles resistance change and the mode of its coding back with wireless signal sent.This nib is made by the less or wear-resisting flexible material of friction factor, can prevent to scratch screen and write good hand touch.
This signal processing module also is connected with battery.
Compared with prior art, the utility model has following beneficial effect:
Because having used the pressure signal of pressure responsive element when writing handles, can make written handwriting no longer is the same linear demonstrations of single stroke of thousand people, but follow the variation of writing pressure and change, make final display effect as hand-written authentic work, true reappearance individual writing style provides good handwriting input effect.

Fig. 3 is the ingredient synoptic diagram of the utility model signal processing module;
Fig. 4 is the corresponding relation figure between the utility model pen point pressure and the oscillation frequency.
[embodiment]
Please refer to Fig. 1, be a kind of embodiment of the utility model photoelectricity pressure induction pen, the illuminator 5 that it comprises shell 1, pressure frequency conversion sensor 2, is installed on the diffuser 3 of shell 1 front end, is installed on the nib 4 on the diffuser 3 and is installed on enclosure.Nib 4 is made by the wear-resisting material of flexibility, and its not writing on screen can scratch screen.
By the diffuser 3 of ingenious design photoelectric pen front end, make diffuser surface 7 have the effect that dispersed light beam converges again, can walk around nib 4 through the continuous refraction on diffuser surface 7 and shine the place ahead of nib 4 by the light of the emission forward of illuminator 5 emission.
Pressure frequency conversion sensor 2 is converted into frequency change with the pen point pressure of sensing, and is converted to wireless signal after handling by signal processing module 6 and sends, and total system is by battery 8 power supplies.
The ingredient of signal processing module 6 as shown in Figure 3, the pen point pressure signal is converted to quartz crystal oscillation frequency variable signal after signal reception/converting unit, this signal sends through transferring to the wireless signal transmitting element after the signal encoding cell processing again, and all these work all are to finish under the control of controller.
Corresponding relation between pen point pressure and the oscillation frequency as shown in Figure 4.
X-axis is a pen point pressure axle 12, and the y axle is a quartz crystal oscillation frequency axle 13, through measuring, shown in the corresponding relation curve 14 between the two.The nib pressure is big more, the quartz crystal oscillation frequency is big more, the person's handwriting that the utility model photoelectricity pressure induction pen is write out is heavy more and stroke is thick, but show the weight size variation of written handwriting according to the corresponding relation relative set between pen point pressure and the oscillation frequency, reach as writing effect as the hand-written authentic work.
Fig. 2 is the another kind of embodiment of the utility model photoelectricity pressure induction pen, and it comprises shell 1, the quick resistance 22 of pressure, nib 4, illuminator 5, signal processing module 6 and battery 8.Nib 4 is made by the wear-resisting material of flexibility, and its not writing on screen can scratch screen.
The pressure that produces when writing passes to the quick resistance 22 of pressure through nib 4, after conversion the pressure variation is converted to resistance change, and this resistance change signal is handled by signal processing module again.Signal processing module is formed referring to Fig. 3, and signal processing is identical with above-mentioned first embodiment.Under the control of controller, the pen point pressure signal is converted to quartz crystal oscillation frequency variable signal after signal reception/converting unit, and this signal sends through transferring to the wireless signal transmitting element after the signal encoding cell processing again.
