Abstract
The utility model discloses a computer handwriting board capable of displaying handwritings, which comprises a writing pen, a display device and a touch panel. The pen point of the writing pen is made of steel or iron; a coil is arranged at the top end of the pen point; the display device adopts a magnetic handwriting white board; and the touch panel adopts an electromagnetic induction panel and is arranged below the magnetic handwriting white board. The handwriting board provided by the utility model adopts the magnetic handwriting white board as the display device, so that not only can writing traces be displayed, but also either an expensive LCD screen or a display processing circuit is required, which greatly lowers the cost of the handwriting board. Furthermore, the utility model has wide application prospect.
Description
Technical field
The utility model relates to board, relates in particular to a kind of computing machine handwriting pad that shows person's handwriting.
Background technology
Along with the development of computer man-machine interacting technology, handwriting pad has obtained significant progress as a kind of input equipment of computing machine, and is particularly very useful for the people who dislikes using keyboard or uncomfortable use Chinese character coding input method.In addition, handwriting pad can also be used for accurate drawing, for example, can be used for circuit design, CAD design, graphic designs, drawing etc.
Handwriting pad generally is to use a special pen, perhaps points writing words or drawing in specific zone.The track record that handwriting pad is passed by pen or finger by the whole bag of tricks gets off, and advances to discern and handles by calculating then.
Existing handwriting pad is set the handwriting area of a specific size usually on device, the contact panel material is used in this zone, the user contacts with this contact panel by finger or pen, and the track that the contact panel material will be write is passed to computing machine and is converted into coordinate information and shows on screen.This handwriting pad can not be simultaneously displayed on the person's handwriting of writing on the contact panel of handwriting pad as writing on paper truly, and the person's handwriting that the writer must observe when writing on the computer screen shows, therefore, can not accomplish the trick unification.When eye gaze handwriting pad, do not know the person's handwriting effect write, when eye gaze screen, can only control finger by feel or pen is write on touch pad, be difficult to the drop point site of control style of writing.Therefore, write on handwriting pad with traditional bigger gap of ways of writing existence, the user must have individual learning process, especially not too is fit to beginner's uses such as children.
A kind of handwriting pad that shows with person's handwriting is also arranged on the market, and this handwriting pad is placed a LCD display below transparent contact panel, when point or nib when contact panel streaks, its person's handwriting can be presented on the lcd screen in real time.This structure has improved the cost of handwriting pad undoubtedly greatly because increased a lcd screen, not too suits large area to popularize.
Therefore, how solving common handwriting pad can not show written handwriting on contact panel problem, replace expensive LCD display simultaneously, is to develop the technical matters that handwriting pad needs to be resolved hurrily in the industry.
Summary of the invention
For solving above-mentioned problems of the prior art, the utility model proposes a kind of computing machine handwriting pad that shows person's handwriting, this handwriting pad comprises: lettering pen, display device and contact panel, it is characterized in that: the nib of described writing pencil adopts steel or irony nib, the nib upper end has coil, shown display device adopts the hand-written blank of magnetic, and described contact panel adopts the electromagnetic induction panel, and is positioned at the below of the hand-written blank of magnetic.
The hand-written blank of described magnetic below is provided with a slide bar mechanical hook-up in order to magnetic is removed from the blank top layer, the two ends of the cls slide bar guide groove of this device respectively are provided with a microswitch, this microswitch links to each other with the circuit of handwriting pad, is used for the cls signal of hand-written blank is passed to Computer Processing.
The handwriting pad that the utility model proposes can be installed in the protection housing, and is connected with computing machine by USB mouth or serial ports.The handwriting pad that the utility model proposes also can integratedly be fixedly mounted on the computer input keyboard.
Compared with prior art, the handwriting pad that the utility model proposes adopts the cheap hand-written blank of magnetic as display device, not only can show handwriting trace, also needs not be with expensive lcd screen and display process circuit, greatly reduce the cost of handwriting pad, have a extensive future.
Description of drawings
In order to be well understood to the technical solution of the utility model and advantage more, below in conjunction with accompanying drawing and preferred embodiment the utility model is described in detail, wherein, Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises: lettering pen 1, display device 2 and contact panel 3.Display device 2 adopts the hand-written blank of magnetic, its principle of work be streak on whiteboard surface by a lettering pen that has steel or an irony nib in, nib is adsorbed onto the blank top layer with the magnetic under the translucent blank, thereby demonstrates the track that nib streaks.Therefore, the nib 11 of the writing pencil of handwriting pad adopts the nib of steel or irony in the utility model, and the nib upper end is provided with coil 12.The hand-written blank of magnetic is identical with the magnetic white board structure that existing children study is write, its as display device of the present utility model be positioned at contact panel 3 above.Contact panel 3 adopts the electromagnetic induction panel, its principle of work is by after the energising of the wired circuit below the hand-written blank 2 of magnetic, in the certain space scope, form electromagnetic field, when the nib that has coil streaks from field region, nib also can produce a corresponding magnetic field, because electromagnetic conduction is untouchable, causing when using nib not touch handwriting pad also can be by the position that interacts nib in magnetic field, the surface that touches handwriting pad when nib will be carried out software identification automatically, thereby reaches the effect of handwriting input.This technology is widely used at present, mainly is to be determined by its good performance.The user can carry out smooth writing with it, and feel is also fine, draws of great use.
The hand-written blank of magnetic below is provided with a slide bar mechanical hook-up in order to magnetic is disposed from the blank top layer, so that write again.The utility model is respectively placed a microswitch 23 at the two ends of slide bar guide groove 21, this microswitch links to each other with the circuit board of handwriting pad, when cls slide bar 22 touches microswitch, just the blank person's handwriting is removed when finishing, microswitch 23 sends the signal of a switch closure to circuit board, this signal sends to computing machine in order to the dump screen after handling by the handwriting pad circuit board.
The handwriting pad that the utility model proposes can be installed in the protection housing, and is connected with computing machine by USB mouth or serial ports; Also can integratedly be fixedly mounted on the keyboard.The handwriting pad that the utility model proposes can show handwriting trace simultaneously on board and screen, convenient and practical.
