'It is often necessary to print a number of characters or patterns on the same keycap. For example, the key cap may have English letters at the same time." At the same time, there is also the indication of the π of the input method, and the indication of the 颉 input method may also be used to represent the different keycap meanings. Therefore, in the limited surface of the upper surface of the stomach, it is necessary to simultaneously Characters such as "Α", "门" and "曰" are printed, or even some special symbols are added. For example, the numeric keypad on the right side of the keyboard of the general desktop computer can be switched to control the movement of the cursor. The keys are as above and below the 'four left and right direction keys'. Therefore, in addition to the printed numbers, there are also arrow patterns or special control mark characters such as Home, End, PgUp, PgDn, etc. In the above, when there are so many keys When arranged on a standard keyboard at the same time, the entire keyboard surface is very complicated 'this situation is easy to cause visual confusion of the user', so that the user can not easily see the key words there, especially for computer beginners. M364876 It’s harder to say, so if the key cap can be used to switch between different input methods, it only shows

Please refer to FIG. 2 for a schematic diagram of the structure application of the conventional light guide plate with the pattern layer. In the application of the light guide plate, the light 13 emitted by the light guide plate 1G is then directed to a pattern layer 2'. The pattern layer 20 has a pre-designed light transmission. The area 21 and the opaque area 22, the opaque area 22 will block the light 13 emitted by the light guide plate 1G from being penetrated, and the light-transmitting area 2 will penetrate the core 13 to allow the latter to be externally _ Insufficient time is still identifiable _ The role of the known light guide plate on the 2G layer is only to provide backlight, as for the display pattern is determined by the pattern layer covering the light guide plate, such as the number on the phone keyboard and other Symbol, when the pattern layer on the keyboard is removed, usually only the surface light source formed by the action of the light guide plate is seen. The Republic of China Patent No. m3779 "Light Guide Plate and Pattern Display Device Using the Light Guide Plate" provides a skirt that directly uses a reflection point to arrange a pattern on a light guide plate, which is provided with a fractal small square on the bottom surface of the light guide plate. Grid, each small square can be 4 M364876 as a - pixel unit, the square square ^ ρ in the pattern to be displayed Jr [provided a groove with a right-angled triangle, and the slope of the 氕Faced into the light surface, the rest of the squares are not treated, that is, the 捭 丨 丨 丨 丨 丨 , , , , , , , , , 丨 丨 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽 凹槽When the cut is fine, the pattern becomes clearer. - The above-mentioned Patent No. 1283779 mainly provides a display of the Lecco (4) layer to be directly combined with the light guide plate as a pattern. However, the device can only provide a relative reduction in the utilization of the light guide plate by providing a single pattern φ. In addition, the keys of the traditional keyboard are mostly switch-switching type, that is, the switch contact control is used, and when the button is pressed, the input signal is transmitted to the computer due to the contact contact, and the contact is released after the button is released, so that the signal is interrupted. It is confirmed by the purpose of the button, and because the key cap has a certain height and the contact/disengagement of the button contact has a certain stroke, the thickness of the keyboard cannot always be greatly reduced. In view of this, the present invention provides a touch keyboard input device with pattern switching, which can switch between different light guides of several light guide plates, and can respectively display patterns on different light guide plates, and utilize a touch panel or a triangle positioning device. Detects the keys entered by the user. The position display is really necessary. [New content] The main purpose of this creation is to provide a touch keyboard input device with pattern switching's use of a plurality of light guide plates to be stacked, and different light source switching between the light guide plates can be used to make different light guide plates The pattern is displayed and the position of the button input by the user is detected by using a touch pad or a triangle positioning device. 5 M364876 Supplement This author is convinced that the novel features are detailed in the scope of the appended claims. However, the novel structure, purpose and advantages can be more easily understood by reference to the following description and accompanying drawings. [Embodiment] This creation uses a multi-layer light guide plate to display the key cap characters or function patterns on the keyboard instead of the conventional way of printing characters or symbols directly on the key cap. Each button position of each layer of the light guide plate can be displayed only. a character or pattern, for example, at the position of the English letter ,, the first layer of light guide plate displays "A", the second layer of light guide plate displays "gate, the second layer of light guide plate displays "曰", and the light guide plate displays characters Or the method of patterning is to make the light guide plate have the character or pattern by printing a reflection point or molding a dot structure on each layer of the light guide plate, and installing a light source on the side of the light guide plate, and the total light is reflected when the light enters the light guide plate by the light source. While advancing, when the reflection point or the dot microstructure is hit, the total reflection is destroyed, so that the light is emitted from the front surface of the light guide plate, thereby displaying characters or patterns, so when only the light source of the first layer light guide plate is lit, the button position Shown is the dot pattern on the first layer of light guide plate, such as the aforementioned "A". When the light source of the second layer of light guide plate is lit, the button position shows the second layer. The dot pattern on the light plate is, for example, the aforementioned "n". When only the light source of the (four) three-layer guide is lit, the button position displays the dot pattern of the third layer of light guide plate as the "day" as described above, by using Control whether the light source of each layer is lit or not to switch the text or pattern displayed on the keyboard, and the switching mode can be switched on the keyboard or controlled by software. At the same time, the touch keyboard of the present invention uses a touch pad or a triangle positioning device. To replace the input method of the contact control. The touchpad can be capacitive or resistive.
