Embodiment:
Also the present invention is described in further detail in conjunction with the accompanying drawings below by specific embodiment.
Be handwriting input emitter circuit block diagram of the present invention as shown in Figure 1, it only shows circuit part, does not draw as for mechanical parts such as a pen core and shells.This part circuit comprises pen core pressure-detecting device 11, mechanical wave generation device 12 and optical synchronous signal generation device 13, described pen core pressure-detecting device 11 and pen core mechanical connection, be used to detect writing pressure and producing trigger pip of producing on the pen core, its trigger pip output terminal links to each other with optical synchronous signal generation device 13 with mechanical wave generation device 12, is used to trigger mechanical wave generation device 12 and optical synchronous signal generation device 13 and produces respectively simultaneously and transmit mechanical waves and optical synchronous signal.
Wherein, but pen core pressure-detecting device 11 adopts pressure sensors or push switch or piezoelectric film, as long as can detect pen core whether write just passable.
Described mechanical wave generation device 12 is ultrasonic generator or audio-frequency generator.Because this class velocity of wave propagation much smaller than the light velocity, will produce a mistiming from being transmitted into reception institute's elapsed time and light signal like this.
Described optical synchronous signal generation device 13 is infrared transmitter or optical transmitting set or wireless transmitter.The velocity of propagation of this class signal is 300,000 kilometers of per seconds, much larger than mechanical velocity of wave propagation.
Of the present invention one big advantage can adopt common refill for ball-point pen to write (on common paper) exactly, does not only change writing style, and the also warmer nature of feel when writing.
The more accurate reflection pen tip position in the position of calculating in order to make, described mechanical wave generation device 12 and optical synchronous signal generation device 13 preferably are arranged at the position of nib top near nib.
Shown in Figure 2 is the circuit block diagram of handwriting input receiving trap, it comprises mechanical wave pick-up unit 22, optical synchronous signal pick-up unit 21, range finding calculation element 23 and computer interface 24, described mechanical wave pick-up unit 22 links to each other with range finding calculation element 23 with optical synchronous signal pick-up unit 21, be respectively applied for and receive mechanical wave signal and the optical synchronous signal that the handwriting input emitter sends and be sent to range finding calculation element 23, range finding calculation element 23 is used for calculating according to the mistiming of mechanical wave signal and light signal arrival the location coordinate of hand input device nib, its output terminal links to each other with computer interface 24, be used for calculate location coordinate be input to computing machine.Need to prove, also can not establish range finding calculation element 23 in this receiving trap, directly in the signal that the receives input computing machine, by the computing machine calculating of finding range.
Corresponding with the mechanical wave generation device 12 in the emitter, described mechanical wave pick-up unit 22 corresponding employing ultrasonic detector or audio receivers.
