Description

1227437 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a keyboard structure, in particular, a font that can change the font on the keys of a keyboard as the input needs, so as to make the keyboard font full A keyboard structure with a switchable key font that meets different needs and facilitates keyboard font settings in different regions. [Previous technology] Press. At present, computers are mainly input by keyboard operation, so the keys on the keyboard are printed with various letters or fonts, and the arrangement of the letters on the keyboard varies with the language of each country. For the need of rotation, different sets of keyboards must be printed for use. This will increase the number of keyboards that need to be made, which is quite inconvenient, and also increase the number of original products, making the control of raw materials more difficult. The different types of keys with different appearances have higher complexity and are not conducive to the development of the product business. There is also a keyboard provided on a leather computer or an information communication device (CojjjMjjicator) because the size of the printable font is also small because of its small size. Generally, ^ round input is often used with different input methods to input by keyboard, and Because different input methods ^ print different font radicals on the keyboard, if palm computers or information communication equipment need to print fonts other than English letters, it is often difficult to print all the required characters due to insufficient printing space. . Because of the commonly used keyboards on the market, the common input method radicals are printed on the keyboard, that is, the font of the key = becomes quite small and the disk surface appears complicated, which increases the operator's load. The ideal keyboard font setting, so how to solve the problem of key style: the use of different needs and production layout, is the industry's important direction to be further breakthroughs and improvements.

1227437 V. Description of the invention In view of the design solution and the key word change concept, the invention has the present invention, which can streamline the keyboard. The hair structure, which is greatly promoted. The structure of the present invention is difficult, and the structure of the present invention is as follows. The keyboard of the present invention is used by the user to display the keyboard and display the keyboard. (2) The aforementioned keyboard is not ideal. The keyboard of the present invention is desired. The layout of the keyboard according to the font can make the keyboard's manufacturing easier and eliminate the key. The key can be better — it can improve the display on the key, and it can be switched to achieve the surface. A more structured service is generated. It is to provide fonts on one key and to meet the purpose of improving the economic benefits of the characters on the keys. The purpose is to print different fonts on the tray. The purpose is to remotely select the fonts set for the above purposes. 'And the fact that the key font is printed and produced in a complicated way, the inventor of the present case can change the production industry and the type of society. It can be changed according to the needs. Shapes and symbols Glyphs, symbols, and functions, as well as the disadvantages of the combination and display of the discs, and their deployment have begun to develop and test the profitability and practicability of the public. The keyboard knots of the key fonts have been used for a long time. In order to meet the needs of font operation and application, the keyboard for changing the key font is simplified and convenient, and it is a design function that makes it difficult to change the keyboard of the key font and control the raw materials in the development of the product business. The compatibility of the keyboard for changing key fonts can be compared, and the technical means used to facilitate the operation of the keyboard are based on the keyboard's own font and content.
