Description of the Invention: [Technical Field] The present invention relates to electronic whiteboards and optical recognition technologies, and also relates to the field of handwriting input pads and touch pads in an operation of the present invention. [Prior Art] An electronic whiteboard is a product that can convert a writing material written on the electronic whiteboard into an electronic file. Among them, how to collect the written materials, ^ important research topics of the product, followed by examples to illustrate several related technologies. In the new patent case No. 395643, the large-scale flat-mounted scanning device on the JR board or whiteboard is disclosed. 4, the optical scanning method is used to collect the book g on the board. In the new patent case No. 458334, the touch screen with conductive surface is exposed, and the pen is in contact with the surface of the touch screen. The J surface will be passed to the computer via the - control circuit. #重接触位 of the surface contact Magnetization _ No. in the new patent case, the disclosure - radio reception. When writing in the field, the oscillating signal will be transmitted by the large-scale circuit sensing board. In the patent case, when the writing-writing part of the magnetic layer is written, the sensing layer will receive the electricity emitted by the electromagnetic pen. In the invention patent No. 392,232, an optical identification is disclosed on a housing of an integrated circuit chip, and the optical identification code can be read by an optical reader. The case also refers to the US 5, 389, 770 case to talk about ~ special optical identification code and reading code and decoding method and device. SUMMARY OF THE INVENTION The present invention provides a new optical input device for use in computer privacy control panels and electronic whiteboards and the like. The optical input device includes two optical wheeling plates and an optical reader. An example of the optical input board includes an encoding layer and a transparent layer. The top surface of the encoding layer is printed with a plurality of = identification patterns, each of which represents its own location and has a property. The transparent layer is bonded to the code layer _ face for the light to slide thereon. Another example of the optical input board is further included - the bottom layer. The bottom layer is superimposed on the bottom surface of the coding layer, and the coding layer itself knows that the color of the difficult case is too shallow to interfere with the writing data written on the transparent surface, and the bottom layer 4 is combined with the coding layer. The mask has a color H. In any case, the knowledge that the optical reader slides on the transparent layer (4) is read by the light. The optical reading reads an identification pattern every time. Equivalent to reading - a position point. This means that each position point on the sliding track of the optical reader will be processed into relative electronic money. These electronic signals pass through the computer system and corresponding The processing of the recording body, the electric (10) system can know the current position of the optical reader by using some electronic signals, and even can store it: the optical device is displayed on the display device. The sliding trajectory is in the electronic trough case. [Embodiment] Pure:: Read the first figure 'expressing the optical wheeling device of the present invention - a filial piety = example _: wherein the optical input board (1) includes - The code layer brush has a translucent layer (1 1 top surface of the code layer (1 0 ): = noon a screening pattern (12), each of the identification patterns (12) is at a position 'and unique. The bottom of the transparent layer (11) is combined with the top surface of the woven rhyme (1Q), the top of the transparent The surface is hard flat, Jin & , ) ( 1 1 w ― the escort slides on it. For example, make a square i glass plate, _ plate or dust plate, snoring optical reading ^ (2) in it In the bean, 3n::2) includes a reading portion (20) and a processing circuit 1) connected to the reading portion (2 〇). The reading portion (2 pattern shooting (= 7 two camera) '俾 By optically reading the read results of the recognition; ^ (4) (2 〇) ϋ top surface, so as long as the top surface of the transparent layer (1 !) slips 1 / light and pattern U2) It is unique and represents: its body: again: ° (2) The mother reads a recognition pattern (12), which is equivalent to 1322091. It takes a position in Jing, or a coordinate. This means that the optics Each position point on the slip track of the reader (2) is collected and processed into corresponding electronic signals, which are then processed by a computer system and corresponding application software. The brain system can know the current position of the optical reader (2) based on the electronic signals, and even can trace the trajectory of the optical reader (2) on its display and store it as an electronic device. For example, the optical reader (2) writes a character on the top surface of the transparent layer (1 1 ), then, on the display, a corresponding A word is displayed. Case (丄2) The higher the density, the higher the resolution of the slippery traces obtained in the future. Based on empirical knowledge, the density of these recognition patterns (i 2 ) can be as high as 2400 dpi. In other words, the example shown in the figure-picture is quite suitable for use in handwriting input board products' and is also suitable for use in computer cursor position control boards to replace the t〇uch pad currently used in notebook computers. Referring to the second figure, there is shown another preferred embodiment of the optical input device of the present invention, wherein the disclosed optical input panel (la) includes a coding layer (10a), a transparent layer (work la), and A bottom layer (work 3). The coding layer (i 〇a) is also printed with a plurality of identification patterns (i 2 ) which are similar to the above-mentioned coding layer (丄〇), and the transparent layer (丄W is also associated with the above transparent layer ( 1 1 ) is the same, it is not described. In particular, the bottom layer (1 3) is superposed on the bottom surface of the coding layer (work a), and the coding layer (10 a ) itself is transparent, and the identification patterns are The color of (Work 2) is so shallow that it does not interfere with the writing of the top surface of the transparent layer (1 1 a ), and the surface of the bottom layer (13) overlaps the coding layer (1 Q a ). a color, such as white or black. Also shown in the second figure is a pen-shaped optical reader (2a) comprising a reading portion (20a) and a processing circuit (2xa), this portion The same as the optical reader (2) described above, which will not be described. The difference is that the optical reader (2 a ) further includes a (2 2) system and the reading portion.
