Introduce two kinds of mode of operations of this talking pen respectively below in conjunction with above-mentioned point-of-reading device:
The learning pen pattern---during use, open the special textbook that is printed with specific two-dimensional invisible code or will be printed with smooth being layed on the common teaching material page of transparent film of specific two-dimensional invisible code, when talking pen is clicked the teaching material relevant position, imageing sensor 32 is taken in the two-dimensional invisible code image of this position and is sent it to coding chip unit 310, coding chip unit 310 is to send processing unit 100 to behind the number address code and with it with this two-dimensional invisible code image transitions, processing unit 100 is sought this number address code corresponding audio/video data in the address stored storehouse in storage unit 410, and this audio/video data is played back by voice unit 420/ display unit 430.The corresponding coordinates regional of each two-dimensional invisible code image, the printing method of two-dimensional invisible code is existing open at Chinese patent ZL02122633.4, and the content in this patent is attached to herein by reference.
The emission pen mode---during use, common teaching material is tiled on the reading main frame 800, when talking pen is clicked the teaching material relevant position, wire-wound telefault 31 produces a wave of oscillation signal under the driving of capacitance three-point type low-frequency oscillation driving circuit 210, send this wireless signal by nib 11, and pass to the scan control plate after conduction web plate 810 receptions by the reading main frame, by the scan control plate determine its click position coordinates and send this coordinate the microprocessor of main control system 820 to, thereby make main control system 820 microprocessor carry out read operation at described position signalling.
Below introduce the use flow process of the utility model talking pen: when the user presses the nib 11 of talking pen in switching controls between above-mentioned two kinds of patterns, under the pressure that the user bestows, imageing sensor 32 can give second circuit board 3 one power of pointing to a shell 1 inboard, this power moves against the force of the spring to first circuit board 2, touch-switch 4 is pressed; The processing unit 100 of talking pen is received after touch-switch 4 presses, then start imageing sensor 32 and coding chip unit 310 and carry out image scanning and decoding respectively, if this pattern does not detect correct decoded signal, then switch to (being point reader emission pen mode) under another pattern.In the present embodiment, start imageing sensor 32 earlier, promptly give tacit consent to talking pen as learning pen.If imageing sensor 32 has the invisible two-dimensional codes of absorption image, then send coding chip unit 310 to, coding chip unit 310 is a number address code and when sending it to processing unit 100 with the invisible two-dimensional codes image transitions, processing unit 100 is sought this number address code corresponding audio/video data in the address stored storehouse in storage unit 410, and this audio/video data is played back by voice unit 420/ display unit 430.If imageing sensor 32 does not detect the signal of stealthy sign indicating number, and the closing image sensor function is opened LC wave of oscillation emission function, makees the emission pen of point reader this moment and uses.The conduction web plate 810 of reading main frame 800 has received then start-up control main frame 820 work of signal.Know that by above-mentioned after touch-switch 4 was pressed, talking pen switched, and up to detecting respective signal, then begins the work under this pattern between learning pen and two patterns of emission pen; If two patterns continue not detect signal, then can the people after being defined in the switching several times, enter battery saving mode.After the pressure of written 11 ends was removed, under the effect of spring 33, touch-switch 4 disconnected the talking pen power cut-off.
Seeing also Fig. 5 is the synoptic diagram that talking pen uses as learning pen in the utility model preferred embodiment.As shown in Figure 5, talking pen 900 is pressed nib 11 and conducting touch-switch 4 on books 700, then can utilize the stealthy sign indicating number image (not shown) on its imageing sensor 32 identification books 200, and the literal that prints on stealthy sign indicating number image-region and the books 700 is corresponding.The described stealthy sign indicating number of coding chip unit 310 decodings, be the image transitions of stealthy sign indicating number number address code and send it processing unit 100 of talking pen 900 to, processing unit 100 is sought this number address code corresponding audio/video data in the address stored storehouse in storage unit 410, and this audio/video data is played back by voice unit 420/ display unit 430.
See also Fig. 6 a to Fig. 6 b, be the structural representation of point-of-reading device among the utility model first embodiment.As shown in the figure, point-of-reading device comprises talking pen 900 and reading main frame 800.In first embodiment that the utility model provides, this reading main frame 800 adopts split type reading main machine structure, comprises conduction web plate 810 and separable main control system 820.Conduction web plate 810 is wired to scan control plate (not shown) and is connected on the main control system 820, and the scan control plate is used to receive the position signalling that conversion conduction web plate 810 receives, and signal is passed to main control system 820.Main control system 820 comprises processor, power supply, storage unit, display unit, keyboard, voice unit, selects suitable audio/video to play in order to the signal that receives according to scanning conduction web plate.Because what use in the present embodiment is split type point reader, its main control system 820 parts can separately be carried and use with respect to the conduction web plate, and are more convenient in actual use.
See also the structural representation of Fig. 7 for point-of-reading device among the utility model second embodiment.Show that as Fig. 7 point-of-reading device comprises talking pen 900 and reading main frame 800 equally.In second embodiment that the utility model provides, reading main frame 800 adopts traditional integral type reading main machine structure.The main control system 820 of this reading main frame 800 is set directly at conduction web plate 810 sides.This shows that the talking pen that the utility model provides can combine with any reading main frame well known to those skilled in the art, so that a kind of point-of-reading device that has the learning pen function simultaneously concurrently to be provided.
In sum, the utility model is realized the function of learning pen by scan module and read module are set in having the talking pen of emission function, thereby the function of talking pen and learning pen is united two into one, it can be cooperated it to discern common papery teaching material with the reading main frame as the emission pen, it can be broken away from the reading main frame as learning pen again and discern the special teaching material that is printed with particular code (stealthy sign indicating number).In addition, point-of-reading device of the present utility model also has the function of point-of-reading device and learning pen simultaneously, and dual-use improves cost performance greatly, has made things convenient for carrying and using of user.
