The user can be positioned over 212 at this positive pole 211 and this negative pole with two batteries 300 in regular turn from the opening 203 of this second housing 202, with the power source as present embodiment.At this moment, this transformer 213 can will become the required voltage of present embodiment from the voltage transitions of described battery 300.This starting switch 214 has a teat 214 ' that extends to this trigger element 26 from the surface, this teat 214 ' is pressed into this starting switch 214 can starts this starting switch 214.In addition, when the angle theta of this substrate 210 and level is in an angular range (for example 30 °～70 °), this angle switch 215 can start, and desires to hold pen in order to the detecting user and prepares the state write.

And the user depresses this laser button 23 can start these laser contact switches 216, and use when making this laser module 22 send a laser beam (figure does not show) for speech or explanation.In addition, can open described left and right sides contact-making switch 217 after depressing described left and right press key 24, because described left and right sides contact-making switch 217 is right and left key designs of simulation slide-mouse, therefore depress the towing that can carry out figure behind the described left and right press key 24, or function such as open function menu.And can open the described contact-making switch 218 that skips after depressing the described button 25 that skips, with the last nextpage handoff functionality of execution bulletin, or the elevating function of electronic screen.

This display lamp 219 can be shinny when this transmitting element 27 sends signals, allows the clearly transmission state of judgment data of user by this.This display lamp 219 is a light emitting diode (LED, light emitted diode) in the present embodiment.And described left and right press key 24 is to use the material of light-permeable, and the light that this display lamp 219 is sent can see through described left and right press key 24 so that the user observes.

This trigger element 26 comprises that a triggering support member 261, that is arranged at these second substrate, 210 front ends movably is arranged at the control lever 262 of these triggering support member 261 front ends, and a nib 263 that is arranged at these control lever 262 front ends.This triggering support member 261 has a hook part 264 that extends forward from the surface.This control lever 262 has slots 265 that engage mutually with this hook part 264.

When the user should nib 263 and for example be that objects such as blank or Projection Display curtain (figure does not show) are when contacting, shown in Fig. 1,3, this nib 263 can promote this control lever 262 because be under pressure simultaneously and move to this second substrate 210 with this triggering support member 261, and this teat 214 ' is pressed into this starting switch 214, and then start this starting switch 214.

It should be noted that, when the user picks up this electronic pen 2, the angle that these angle switch 215 meetings are write because of the user starts writing is opened earlier, make the energy supply control module in second substrate 210 begin to start the formation readiness, person to be used is with object such as electronic pen 2 aforesaid blanks of contact or Projection Display curtain and after triggering this starting switch 214, this transmitting element 27 just can begin to carry out the transmission of data signals.

As shown in Figure 1, 2, this transmitting element 27 comprises that one extends and around the transmission support member 271 of this axis along an axis, and one is arranged at the transmission part 272 that this transmissions support member 271 is surperficial and be electrically connected with this second substrate 210.This transmission support member 271 has a cylindrical preceding support portion 273, reaches one from the back support portion 274 of these preceding support portion 273 ends to these second substrate, 210 extensions.This transmission part 272 has one in order to receiving the acceptance division 275 from an input signal of this second substrate 210, and one exports the output signal sending part 276 of (figure does not show) by the mode of radiation.This sending part 276 is arranged at this 273 surfaces, preceding support portion, and this acceptance division 275 is arranged at this 274 surfaces, support portion, back.

In addition, as shown in Figure 4, be the side view of this transmitting element 27, this transmission part 272 is arranged at this transmission support member 271 surfaces.

It should be noted that this transmission part 272 is to be made by polyvinylidene fluoride (PVDF, polyvinylidene difluoride) in the present embodiment.PVDF is a kind of very practical material for piezoelectric transducer, because it is easy to be cut or plastotype, and is not easy to break.In addition, PVDF is easy to produce binding with other materials or itself.

Shown in Fig. 1,5, under the situation that this starting switch 214 and this angle switch 215 all start, this second substrate 210 can transmit this input signal to this acceptance division 275, and sending these output signals for described inductor 13,13 ' induction by this sending part 276,1 of this receiver is by waiting inductor 13, the 13 ' signal of being received to calculate the position of this electronic pen 2 in the three-point fix mode.

Wherein, the principle of three-point fix is, this electronic pen 2 is except sending these output signals by this sending part 276, and (RF, RadioFrequency) transmission mode transmits a signal for this second transferring wafer 219 ' and less radio-frequency that simultaneously can be by 2.4GHz.Because the transfer rate of less radio-frequency transmission is fast than the ultrasonic signal that this sending part 276 is sent, therefore the radiofrequency signal that is sent out by this second transferring wafer 219 ' can be detected by this first transferring wafer 14 earlier, described then inductor 13,13 ' just can receive the ultrasonic signal that is sent by this sending part 276 respectively, therefore this inductor 13 and 13 ' receives that the time point of signal and the time point of first transferring wafer 14 radiofrequency signal of receiving can produce respectively the different mistimings, then can further calculate the distance of this inductor 13 and electronic pen 2 by the mistiming, and the distance of another inductor 13 ' and electronic pen 2, again because this inductor 13,13 ' is to be arranged in the same receiver 1 and both fixed distance and be known conditions, so, this inductor 13,13 ' and the phase mutual edge distance of 2 three of electronic pens can learn, and then form three-point fix and calculate the definite coordinate position at these electronic pen 2 present places.

In addition with reference to Fig. 5, described inductor 13,13 ' induction range approximately is 16 square centimeters, during actual the use, must determine the scope of writing earlier, as the scope of writing is as shown in the figure by anchor point 41,42,43,44 frames are limit out when regional, utilize the mode of aforementioned three-point fix, the user can click two anchor points 41 at diagonal angle earlier with electronic pen 2,43 (or anchor points 42,44) can determine a square or rectangular zone of writing automatically, if four anchor points 41,42,43,44 all click, then can determine by described anchor point 41,42,43,44 the linear rectangle that links to each other write the zone, thereafter, by this electronic pen 2 this one write write in the zone mobile, the anchor point 45 of electronic pen 2 will continue to go on record, and receiver 1 can be fixed in arbitrary position of writing the scope outside, only need make described inductor 13,13 ' gets final product towards the scope of writing.

In addition, the described left and right sides contact-making switch 217 of electronic pen 2, when the described contact-making switch 218 of skipping starts, this second substrate 210 also can produce another input signal and be responded to by this receiver 1, to carry out the default feature of above-mentioned described left and right sides contact-making switch 217, the described contact-making switch 218 that skips.

In sum, in the process that this electronic pen 2 moves in the scope of writing, as long as under the state that this starting switch 214 and this angle switch 215 all start, application by ultrasonic signal and less radio-frequency transmission signals, can calculate this electronic pen 2 formed track in whole mobile process in the three-point fix mode easily, and the data of corresponding this track are sent to storage coal body (figure a does not show) storage, or being sent to a display media (figure does not show) immediately shows, so can reach effect of the present utility model.
