New description: [New technical field] The present invention relates to a keyboard device, and more particularly to a keyboard device with a luminous effect. [Prior Art] At present, the keys of the keyboard or mobile phone of the notebook computer adopt a thin key structure, and the thin key structure has the advantages of ultra-thin volume, light weight and precise operation, and is convenient for the user even in a dimly lit environment. The keyboard or button can still be operated, so the relevant industry has developed a design that provides auxiliary lighting, such as: China Announcement No. 516671 "Input Keyboard with Uniform Backlight", Announcement No. 587_ "Keyboard with Backlight Module", Certificate No. M306689 "Light guide plate and backlight module of the keyboard", and the new patent case of the card number 513 "keyboard lighting structure". The design of the keyboard is generally designed to have a light source or a light source under the button. There is a light guide plate, so that the light projection of the light source can only be reflected by the light-transmitting area of the button after being reflected on the nine-plate. However, because the distance between each button and the light source is different, the light transmittance of each button is different, and the light guide plate is a flat plate body having a large reflection angle, so that the light cannot be efficiently concentrated. More lack of shelling. [New content] Therefore, the object of the present invention is to provide a keyboard device with a luminous effect for providing a spoon tomb. The 仏 勾 勾 先 先 先 先 先 先 先 先 先 先 先 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘 键盘a thin film circuit board having a film bottom layer, a film intermediate layer on the film bottom layer, and a film top layer on the film intermediate layer, defining the film bottom layer in contact with the film intermediate layer The surface is a reflective surface, and the reflective surface is convexly provided with a plurality of reflective light guiding points, and one or more light emitting elements are disposed on the bottom surface of the top layer of the thin film circuit board, and penetrate the intermediate layer of the thin film and The bottom layer of the film. The effect achieved by the novel is that the light emitted by the light-emitting element can be uniformly radiated upward under the reflection of the reflected light guiding point, thereby providing a uniform light guiding effect. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 1 and 2, a preferred embodiment of the keyboard device 2 of the present invention has a button unit 3 and more than one light-emitting element 4. The button unit 3 includes a frame plate 31, a plurality of buttons 32 that attack the frame plate 31, a plurality of elastic members 33, and a film circuit board 34 electrically connected to the buttons 32. The frame plate 31 is a metal plate body, and a plurality of receiving grooves 311 and a plurality of through holes 312 are formed on the frame plate 31 at predetermined positions corresponding to the respective buttons 32. Each button 32 has a plurality of bridges 321 disposed on the frame plate 31, and a plurality of key caps 322 disposed on the wooden bridges 321 . Since the connection between the bridge 321 and the keycaps 322 and the frame plate 31 is a conventional structure, M352722 will not be described herein. As for the bottom surface of the elastic member 33, a protrusion (not shown) is protruded from the bottom surface. Still referring to FIGS. 1 and 2, the thin film circuit board 34 has a membrance bottom layer 341, a membrance middle layer 342 on the film bottom layer 341, and a film intermediate layer 342. A membrance top layer 343. The surface of the film bottom layer 341 that is in contact with the film intermediate layer 342 is a reflecting surface 344. The reflecting surface 344 is convexly provided with a plurality of reflecting light guiding points 345, and the reflecting light guiding points 345 are formed by a light guiding paint. The isolating light guiding spot 345 is disposed at the bridge 321 adjacent to each of the keys 32. The film bottom layer 341 and the film intermediate layer 342, and the frame plate 31 are respectively provided with openings 346, 347, 312 corresponding to the preset portions of the light-emitting elements 4. In addition, a guiding contact 348 is disposed on the film bottom layer 341 of the film circuit board 34 corresponding to each of the protrusions of the elastic member 33. Further, it is specifically noted that the film underlayer 341, the film intermediate layer 342, and the film top layer 343 are all made of a material having good light guiding properties such as polycarbonate (PC) or acrylic (pMMA). Each of the keycaps 2 can be made of a light-transmitting material to increase the light transmission effect. Referring to Figures 1 and 2, the illuminating keyboard unit 2 of the present invention further includes an elastic patch 35 disposed on the film top layer 343 of the film circuit board 34. The elastic member 33 is disposed between the bridge 321 and the elastic patch 35. The end of the elastic member 33 passes through the bridge 321 and is mounted on the bottom surface of the keycap 322, and the other end is in contact with the elastic patch 35, and The stud is inserted out of the elastic patch 35. The light-emitting elements 4 are all light-emitting diodes disposed on the bottom surface of the film top layer 343 of the thin film circuit board 34, and the wires (four) are arranged in such a manner that the light-emitting elements 4 are positioned on the film top layer of the thin film circuit board 34. 343 M352722 Four corners on the bottom. Tampering with p, L 4 , ^ the light-emitting element 4 and penetrating through the corresponding film openings 346, 347 and perforations of the film bottom layer 341, the film intermediate layer 342 and the frame plate 31 of the film circuit board 34 312. / When the field keycap 322 is pressed, the interlocking bridge mi presses the corresponding column of the elastic member 33 to contact the corresponding guiding point to form an electrical conduction loop. The fourth day is that the thickness of the film bottom layer 341, the film intermediate layer 342 and the film top layer 343 of the film circuit board 34 is still a sheet. Therefore, the light-emitting elements 4 pass through the film intermediate layer 342 and the film bottom layer. 341, after the corresponding opening 346 347 and the through hole 312 of the frame plate 31, the horizontal projection light emitted by the illuminating element 4 is projected to the reflected light guiding point 345, and the reflected light guiding point will advance. Reflecting light and diverging upwards provides a uniform (four) light guiding effect. ...the above-mentioned "four" keyboard assembly with luminous effect 2 can achieve the above-mentioned objects and effects of the present invention by the above-described design. However, the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made by the novel patent application scope and the novel description contents are All should remain within the scope of this new patent.
