[0026] 使用时,当该数字笔10用于书写前,先将该数字笔接收装置30固定在书写介质20边缘,当书写时,该压力感测开关160用于感测该笔尖140书写的压力。 [0026] In use, when the front 10 of the digital pen used for writing, the digital pen to the receiving device 30 is fixed to the edge of the writing medium 20, when writing, the pressure sensing switch 160 for sensing that the writing tip 140 pressure. 当压力超过预定压力时,该控制电路单兀162启动该信号发射模块164同时发射激光、第一及第二超声波信号,即该激光发射模块170发射激光,该第一超声波发射模块171与该第二超声波发射模块172分别发射第一超声波与第二超声波,并且该第一超声波发射模块171与该第二超声波发射模块172所发射的超声波频率不同。 When the pressure exceeds a predetermined pressure, the control circuit unit 162 to start the Wu signal emitting module 164 emits the laser at the same time, the first and second ultrasonic signal, i.e., the laser emitter emitting laser module 170, the first ultrasonic transmission module 171 of the two ultrasonic wave transmitting module 172 emit a first ultrasonic wave and the second ultrasonic wave, and the first ultrasonic transmitter module 171 and the second ultrasonic transmitter an ultrasonic frequency emitted module 172 differ. 这样便于后续第一超声波接收模块311与第二超声波接收模块312分别接收预先设定波段的超声波。 This facilitates subsequent first ultrasonic wave receiving module 311 and the second ultrasonic wave receiving module 312 receives a preset ultrasonic band. 该激光接收模块313用来接收该激光发射模块170发射的激光信号。 The laser receiver module 313 for receiving the laser transmitter module 170 emits a laser signal.

[0027] 以该激光接收模块313接收到激光信号的时刻为计时起点,因为光速快于声速,从而激光先于超声波到达数字笔接收装置30,所以将接收到激光信号的时刻作为计时起点(假设时刻为T0)。 [0027] receives the laser receiver module 313 to the laser signal is time for time zero, because the speed of light is faster than the speed of sound, so that the laser prior to the ultrasonic wave reaches the digital pen receiving device 30, the received laser signal point being the starting time (assuming time for T0). 由于该数字笔10能同时发射激光与超声波,所以此处的该激光发射模块170只需要发射较低功率的激光即可,从而可以尽可能降低激光对使用者眼睛的伤害。 Since the digital pen 10 can simultaneously emit laser light and ultrasound, so here the laser emission to the laser module 170 needs to transmit a low power laser can be reduced as much as possible damage to the user's eyes.

[0028] 请参阅图4,该第一超声波接收模块311接收到第一超声波的时刻为Tl,该第二超声波接收模块312接收到第二超声波的时刻为T2。 [0028] Referring to FIG 4, the first ultrasonic wave receiving module 311 receives the first time for an ultrasonic wave Tl, the second ultrasonic wave receiving module 312 receives a second time for an ultrasonic wave T2. 该信号处理单元32分别计算该第一超声波接收模块311距离该第一超声波发射模块171的第一距离以及第二超声波接收模块312距离该第二超声波发射模块172的第二距离。 The first ultrasonic wave receiving module 311 from a first distance from the first ultrasonic transmitter module 171 and a second ultrasonic wave receiving module 312 from the second ultrasonic transmitter module 172 from the second signal processing unit 32 calculates. 具体地,该第一距离为超声波的速度乘以第一超声波的运行时间111,即Hl=Tl-TO,该第二距离为超声波的速度乘以第二超声波的运行时间H2,即H2=T2-T0,再以该第一超声波接收模块311为圆心、第一距离为半径的第一圆与以该第二超声波接收模块312为圆心、第二距离为半径的第二圆在该书写介质20的表面相交,相交的交点即是此时刻T0,笔尖140在该书写介质20表面的第一位置。 In particular, the first distance is multiplied by the first ultrasonic wave velocity of ultrasonic wave running time 111, i.e., Hl = Tl-TO, ultrasonic velocity multiplied by the second ultrasound runtime and the second distance H2, i.e., H2 = T2 -T0, then to the first ultrasonic receiving module 311 as the center, a first distance to a first radius and the second ultrasonic wave receiving module 312 as the center, the second radius of the second distance is in the writing medium 20 intersecting surfaces, that is the intersection point of this time T0, the location of the pen tip 140 of the first surface 20 of the writing medium. 由于书写一笔划时笔尖140会被持续按压,激光、第一及第二超声波也会持续发射。 Since the tip 140 is continuously pressed during writing a stroke, a laser, a first and a second ultrasonic transmitter will continue. 该数字笔接收装置30可在预定的时间间隔后再次接收激光、第一及第二超声波以使该信号处理单元32确定笔尖140在该书写介质20表面书写该笔划的第二位置。 The digital pen 30 may receive the laser beam receiving device again after a predetermined time interval, so that the first and second ultrasonic signal processing unit 32 determines the tip 140 of the writing medium in the writing surface 20 of the second stroke position. 如此类推,该信号处理单元32便可以确定笔尖140在该书写介质20表面书写时的多个位置以识别笔尖140书写的笔划(书写轨迹),例如书写一笔划需要I秒,可以将预订的时间间隔设定为0.1秒,即每隔0.1秒得到一个位置或者轨迹点,从而在I秒内得到多个位置以识别笔尖140书写的笔划(书写轨迹)。 And so on, the signal processing unit 32 can determine a plurality of locations at 140 nib 20 in the writing surface of the writing medium to identify the writing tip 140 strokes (writing track), for example, writing a second stroke require I can be booked time interval is set to 0.1 seconds, to obtain a position or track point every 0.1 seconds, to thereby obtain a plurality of positions in I second to identify the writing pen strokes 140 (writing track). 可以理解,该预定的时间间隔决定了识别的笔划(书写轨迹)的精度。 It will be appreciated that the predetermined time interval determines the accuracy of stroke identification (the writing track) is. 该数据储存单元33用来存储该笔划(书写轨迹)。 The data storage unit 33 for storing the stroke (the writing track).

[0029] 综上所述,本发明提供的数字笔、数字笔接收装置及数字笔书写装置利用了激光与超声波都能准确侦测位置的特点制作而成,该数字笔尺寸大小可以与一般使用的原子笔大小相当、携带方便,而且书写时不需要额外的手写板,即不需在一特定之表面才能使用,使手写更加方便。 [0029] In summary, the present invention provides a digital pen, the digital pen receiving apparatus and a digital pen using a laser apparatus can accurately detect the characteristics of the ultrasound produced by the position, size of the digital pen can be used with the general pens in size, easy to carry, and does not require additional writing tablet, i.e. no need to use a specific surface of the hand easier.
