Description of the Invention: [Technical Field] The present invention relates to a keyboard structure which is difficult to emit light. [Prior Art] Whether it is a desktop computer, a laptop computer, a notebook computer, or a keyboard used in Internet TV, in order to provide a type of key that can be used to clear the keyboard in low brightness or darkness. The ability to have a variety of hairpins, such as the United States 628 side, (10) friends 6199996, 6554442, 6Π9432, Taiwan bulletin number 5〇9955, 465777, 5〇9955, 535385, 438035, 570235, 468833, No. 516671, there is a technique of using a built-in illuminator to shoot the light source outwards, and allowing the person to tilt the disc in a dark environment. However, in each of the above patent documents, there is only an elastic body between the disk key caps of the light-emitting elements in the keyboard, and the suspension mechanism is blocked, and most of the special funds use the keycap, the elastic body and the suspension mechanism as the light-transmitting material. Fcheng (some patents are made of _designed as a neo-optical machine, but the symbol on the keycap is made of translucent material), so that the light-emitting component is emitted in a whole piece of light, and the keyboard is rendered in a backlit type. This (4) light is used to create new _ _, when turning over the operation of the illuminating ^ disk environment is mostly low light, darker, such as aircraft, car and other low-light environment, the keyboard (four) hook light, will cause more Brightness (4) affects other people, and in this low-brightness environment, the user's visual ability on the keyboard is much lower. If the whole piece is bright, use ^ fundamentally difficult (10) to know the character ship on each keycap For those who are unfamiliar with the keycap word symbol, they will often generate a wrong signal and input an incorrect command signal. Based on the above, the applicant has proposed a non-uniform illumination keyboard (Taiwan Patent Publication No. 1230957), which is provided with a shielding member through a light-emitting element for providing a light source in a keyboard and a key cap for receiving the light source. 'The mask is defined at the position of the individual keycaps ^ a light-transmissive area, and the position of the adjacent key caps below the individual keycaps is an opaque area, so that the light-emitting elements

X [ SUMMARY OF THE INVENTION] - The object of the present invention - to provide a - reddish backlight construction, the phase produces a bright (10) 'bright (four) character or symbol at the edge of the keycap, thereby creating a sense of contrast - dark contrast 5 1312956 The visual effect and atmosphere, in addition to improving the ease of the disc in the dark, also enhance the visual and texture of the keyboard. The preferred embodiment disclosed in the present invention includes: an opaque keycap on the key face and a day minus _ character or symbol, and a light emission directly under the keycap The light directly under the key towel can not directly penetrate the keycap, but can only be created by the periphery of the keycap to create a bright outline at the edge of the keycap, and the light is bright and bright. Character or symbol for the above purposes. According to a preferred embodiment of the present invention, a reflective material (4) can be applied to one side of the light source facing the light source to reflect the light from the system, thereby improving the light transmittance and improving the contrast of the backlight. According to the present invention, the towel is provided in the key word or the symbol can be field light or self-powered light to provide a brightly recognizable character symbol. ^Detailed description and technical details of the present invention, the current ship-integration mode [embodiment] The second reading of the second and second figures" is the keyboard of the backlight structure disclosed by the present invention. The disk has a bottom plate IG, and the bottom plate 10 is provided with an elastic body 12'' between the key plate 11 and the bottom plate 10, and the key cap 11 is made of an elastic body. 12 and the support of the suspension mechanism 13 (see "The first coffee ❹ 秘 秘 = = = = = = = = = = = = = = = = = = There is also a backlight unit between the keycap „ and the bottom plate 10, the cladding plate, the shielding member 15 and the component 16: the preferred embodiment of the road region 18 is provided by two layers respectively on the upper and lower electrode surfaces The upper 12 having the pair and the normal state and not in contact with each other is also closed, and the lower core 'when the keycap 11 is depressed' is disposed on the elastic body 181 below the keycap 11, and the bottom of the elastic body 12 is pressed. The terminal 121 is pressed to contact the electrode electrode 182, which can be combined with the circuit design of the keyboard - the electrical signal. 6 1312956 and the light-emitting element 16 In principle, the illuminating light source can pass through the light-transmissive region 18 and the bottom of the keycap 如 can be an electroluminescent panel, a light-emitting diode, and a light guiding device. The main function of the occlusion device is to limit the interference of the light from the key u to the keycap n. The component l _ is completely illuminated by the entire ship domain. (4) The user is visually supposed to be transparent. The component 15 is in the phase passing through the light transmitting region ls === hole] 50 for the light emitting element 16 The emitted light can only be projected directly below the keycap U by the shielding element η G. Due to the circuit board line, most of the light emitted by the light-emitting element 16 from below is not matched.

A preferred embodiment of the line, 'the keycap 11 is a completely opaque element' which can be judged by 1 歹 1 . The key cap 11 is made of a material that is completely opaque or is in the key cap 11 The material of the T-H dye is printed on the surface of the keycap 11 (toward the user's surface) by a self-illuminating material (such as a fluorescent material) 20 (see "3"). Another preferred embodiment (see "Fig. 4") is a coating-reflecting layer 1G on the back side of the keycap 21 (ie, facing the source side) (for example, a metal reflective material). Silver paint), the light that causes the light-emitting element 16 to strike the back surface of the keycap U can be reflected by the gap between the adjacent keycaps 11 by the reflection of the reflective layer 11〇, thereby creating at the edge of the keycap u A bright porch and a brighter effect of the contours ^ Another preferred embodiment 'the character or symbol m of the keycap U surface is a permeable design (see "Figure 5"), A possible embodiment is that the keycap η can be made of a light-transmissive material, and a reflective layer 110 is coated on the back surface of the keycap 11 (ie, the side facing the light source), but is not coated at the character or symbol 12〇. The cloth reflection layer 〗 〖 〇 'except for part of the light can be emitted by the transparent character or symbol ί2 ,, the rest of the light is reflected by the reflective layer 110 and is reflected by the gap between the adjacent keycaps u Further, a bright rim is formed on the edge of the keycap u. The backlight structure according to the foregoing preferred embodiment of the present invention can also be applied to a keyboard structure as shown in FIG. 6, which differs from the keyboard of the aforementioned "second figure" in that the suspension mechanism 13 is a type The bridge 20 is carried, and the bridge 20 is disposed between the keycap U and the circuit board 14 and the bridge 20 is preferably made of a light transmissive material so as not to block the light source 7 1312956. The light of π, and the bottom plate 10 therein is only the remaining components of 15 'and the light-emitting elements'. ^3Construction 丨4, the shielding component is readable. 'Because the clock of the present invention has _ from the word (four), it is a shell-like shape, so it does not make the back I of the entire keyboard appear. The light from the bottom of the keycap η will be in the keycap u = into a bright outline, with a bright character or symbol 12G in the bright key, into the (four) ^ - kind of light and dark contrast visual effect and atmosphere, In addition to improving the texture in the dark, it also enhances the visual and texture of the keyboard. ·-'
