CN2518149Y - Copper sensitive writing board for computer hand writing input - Google Patents

Abstract

The utility model relates to a copper cash induction handwritten board which is used for the handwritten input of the computer, and belongs to computer peripheral equipment, the copper cash induction handwritten board is matched with a special-purpose handwritten pen and used for the handwritten input of the computer. The utility model belongs to the electromagnetic written board, and adopts the electromagnetic induction principle to produce a xy coordinate value, thereby positioning a cursor, and describe the locus. Compared to the original similar electromagnetic handwritten board, the handwritten board has the remarkable characteristic that the electromagnetism receiving function is accomplished through adopting a pound shape copper net which is vertically and horizontally distributed with copper cash. Compared with other similar products, the handwritten board adopting the line distribution has the advantages that the performance is invariable, but the cost is greatly reduced, and thus the handwritten board which has the low cost and the high performance is the handwritten input equipment of the computer.

Description

The copper cash induction handwriting pad that is used for the hand-written typing of computing machine

Technical field

The utility model belongs to computer peripheral, is used for the hand-written typing of computing machine.

Background technology

The handwriting pad hardware vendor has the WACOM of Japan now, the AIPTEK in Taiwan, several families of Chinese princes and dukes department of WINTIME and China.Through years of development, it is ripe that the technology of handwriting pad has become, kind has also increased a lot, if any wireless handwriting pad is that lettering pen is connected without line with palm, also has pressure sensitivity, the handwriting pad of USB, com interface is all sold fast on market, and these handwriting pads divide from principle and also can be electromagnetic type, touch, ultrasonic locating formula, photo-electric etc.At present most widely used is electromagnetic type, and it has the location accurately, the characteristics not fragile, that anti-interference is good.And use the handwriting pad of electromagnetic type principle at present, it is to be made of the net-shape antenna that intersects that insulate anyhow that its electromagnetism is accepted part, be that the interior integrated circuit board (pcb board) of plate is a complete plank, the front of printed-wiring board (PWB) can the cloth horizontal line, the back side cloth vertical line of wiring board is formed net-shape antenna with this.And wiring board cost height, the weight of this pattern are also high, because the processing charges of a wiring board calculates with its useful area, and the wiring board use is a complete plank, in addition the size of antenna area determining on the computer display cursor can reach size, therefore, the electromagnetic type handwriting pad need enlarge the antenna area of oneself as far as possible, also will enlarge the area of pcb board as far as possible, thereby has strengthened manufacturing cost and weight.

Summary of the invention

Owing to the area of the shared printed-wiring board (PWB) of the antenna of electromagnetic type handwriting pad (pcb board) has increased the cost of handwriting pad too greatly, thereby will formerly be used as pcb board that antenna part connects up and partly change the copper mesh that constitutes by copper cash and substitute.Promptly open a square window in wiring board central authorities as shown in Figure 1, the pilot hole that some is respectively arranged on four limits of this window, the pilot hole on wherein parallel both sides is corresponding mutually, per about in the of two, about corresponding hole couple together one by one with the copper wire that insulate, so just constitute several rows of horizontal line that is parallel to each other and the several rows of vertical line that is parallel to each other, form a groined type copper mesh and constitute antenna and come receiving electromagnetic signals.The connection of copper wire as XT1 hole and XB1 hole are coupled together with the also stretching copper cash (not allowing any bending in the line) of an eradication edge, is connected the XT2 hole with the identical copper cash of another root also as shown in Figure 1 again with the XB2 hole ... until being connected of XTm and XBm hole; Equally, YT1 hole and YB1 hole are coupled together with a copper cash, with another root copper cash YT2 and YB2 hole are coupled together again ... after YTm and YBm couple together, so all holes are coupled together one by one.The horizontal line of definable is the Y coordinate, and vertical line is the X coordinate.The copper cash that XT1 is connected with XB1 is connected with the X1 pin of X coordinate module again, and the copper cash that XT2 is connected with XB2 is connected with the X2 pin ... be connected with the Xm pin of X coordinate module with the line of XBm until XTm.The copper cash that YT1 is connected with YB1 is connected with the Y1 pin of Y coordinate module, and the copper cash that YT2 is connected with YB2 is connected with the Y2 pin ... be connected with Ym with the line of YBm until YTm, constitute Anneta module with this.Anneta module is connected with data processing module in the circuit again, and the data that are about to Anneta module are sent into data processing module, after handling with the data processing method of original electromagnetic type handwriting pad, just end product can be sent into computing machine.

It is duplicate that the utility model is compared on performance with original handwriting pad, but reduces greatly on cost, also has necessarily on the weight to alleviate, and greater flexibility is also arranged in appearance design.

Description of drawings:

Fig. 1 is the concrete Anneta module layout of implementing to be used for " the copper cash induction handwriting pad of the hand-written typing of computing machine "

Embodiment

The middle position of the printed-wiring board (PWB) in original Chinese king handwriting pad is emptied, and opens a rectangular window, and 16 apertures are bored on every limit around this rectangular window frame, and the line of the aperture of parallel two opposite sides is horizontal or vertical one by one.Then with enameled wire with upper and lower, left and right aperture one to one couples together and forms the groined type net, enameled wire will be tightened stretching; Every line can not have any bending, and every single line is independently to link to each other mutual insulating between the copper cash with the line on other hole.When writing pencil was write on this handwriting pad, this Anneta module just can be sent end product into computing machine after receiving the person's handwriting signal and reach data processing module and handling, and after handling through Computer Analysis, can demonstrate the writing of being write on display screen again.This handwriting pad is identical with original Chinese king handwriting pad outward appearance, and hand-written area can reach 5*4inch, and resolution can reach 1200dpi, and the cost of manufacture of printed circuit board (PCB) is 50% of a raw sheet, and weight also can alleviate 1/30.

Claims (2)

1. one kind by printed-wiring board (PWB), copper wire, module, the copper cash induction handwriting pad that is used for the hand-written typing of computing machine that shell constituted, it is characterized in that drawing out a tetragonal window, the hole of some is respectively arranged on four limits of this window in the central authorities of printed-wiring board (PWB); About, about put on copper wire one by one in the corresponding hole, form the groined type copper mesh, mutually insulated between copper wire and the copper wire, this silk screen and formation Anneta module after corresponding X coordinate module and Y coordinate module connect.

2. the copper cash induction handwriting pad that is used for the hand-written typing of computing machine according to claim 1 is characterized in that copper wire can select enameled wire for use.
