Description of the invention: [Technical field to which the invention pertains] This creation relates to a button and a method of manufacturing the same, and particularly to a keycap in a button and a method of making the same. [Prior Art] The technique of two-shot forming has been applied to the production of many industrial or consumer products. The related prior art is referred to U.S. Patent 4,935,184. Light-transmitting buttons can also be found in many consumer products. For related prior art, refer to Taiwan Patent Publication No. 285345 or Taiwan Patent Publication No. 200705495. The related prior art of the illuminable keyboard can be referred to Taiwan Patent Publication No. 200802040. For the average person familiar with the technology, each key cap consists of a key top (keyt〇p) and a key skirt (keyskirt). The so-called key skirt is around the top of the key, slightly beveled type of bezel. And the part connected to the top of the key. In terms of current technology and products, the material and color of the key top and the key skirt are the same, and are formed by a single injection molding method. The technique of two-color 'or double material keycaps, or combined keycaps has not been revealed so far' so the aesthetic design of the keycaps has changed. In order to make the appearance and change of the keycap, the present invention proposes a technique and a manufacturing method of a two-color, two-material keycap or a combined keycap. SUMMARY OF THE INVENTION One object of the present invention is to provide a combined keycap to increase the aesthetic variation of the keycap. Another object of the present invention is to provide a method of making a combined keycap. According to an embodiment of the present invention, a combination keycap includes an outer casing made of a first material, which is slightly tubular in shape, and has a hollow inner tube 201243651; and a second The inner casing, which is made of a material, is slightly thin-plate tubular and is embedded in the inner space to be combined with the outer casing. According to an embodiment, wherein the first material is polyethylene terephthalate (PET). According to an embodiment, the outer casing of the crucible comprises a key top, # has a first color, and a key skirt is located around the top of the key, connected to the top of the key, and has a second color to form a two-color Key cap. According to an embodiment, wherein the second material is a transparent material, the outer casing has a light transmissive region for light to pass through. According to an embodiment, the outer casings M + w 1 . and D I are produced by an in-mold forming technique. The manufacturing method according to the present invention-embodiment includes: forming an outer casing by an in-mold forming technique, which is slightly in the form of a film cylinder having an inner space, and the outer casing is composed of a -th material; Forming an inner casing which is slightly thin cylindrical, the inner casing is composed of a second material; and the inner casing is embedded in the inner space of the outer casing to be combined with the outer casing. According to an embodiment, wherein the first material is polyethylene terephthalate (PET). According to the embodiment, wherein the outer casing comprises a key top having a first color; and - the key skirt has a second color to constitute a two-color keycap. According to an embodiment, the pattern or color of the key top, the key skirt is formed in the first material by a coating method or a printing method. Other details and details of the invention will be apparent from the description of the following embodiments and the appended claims. [Embodiment] Referring to Fig. 1, an embodiment of a combined keycap 1〇 of the present invention comprises an outer casing 1 made of a first material (H, which is slightly thinned in a tubular shape, and the film is cylindrical An inner casing 103 made of a second material, which is formed in a thin plate cylindrical shape, and the inner casing 1 (3) is embedded in the inner space to be combined with the outer casing 201243651 101 to form A combined keycap 10. According to an embodiment, the first material is poly-p-ethylene phthalate (ρΕΤ) β. According to an embodiment, the outer casing 101 comprises a key top 1〇1Α, Having a first color, and a key skirt 101Β, which is located around the top of the key, is coupled to the key top 101A and has a second color, so as to constitute a two-color combined keycap 10. According to an implementation For example, wherein the second material is a transparent material, the outer casing 101 has a light transmissive area 105 for light to pass through. The light transmissive area 1 〇 5 corresponds to the function of the key cap, for example, a delete key (delete). The outline of the light-transmitting area 1〇5 is displayed as “delete”, and so on. When the board is arranged with [ED backlight] light can pass through the light-transmitting area 1〇5, so that the user can clearly see the symbol of each button function. There are some methods for making the outer casing 1 〇1, and according to an embodiment The outer casing ιοί is made by an in-mold forming technique (InMoldF〇rming IMF). This IMF method belongs to the conventional plastic molding technology. The above is a description of the two-color combined keycap, and the following is a description of the manufacturing method. The manufacturing method can be fully understood in conjunction with Figures 2A, 2B, 2C, 2D, 2E, 2F. An embodiment of the method for fabricating the keycap of the present invention comprises (1) forming an outer casing by an in-mold technique. 200, the outer casing 200 is slightly in the form of a film cylinder having an inner space, the outer casing 200 is composed of a first material (as shown), and (2) an inner casing 2 is formed. It is slightly thin-plate-shaped, the inner casing 2〇4 is composed of a second material; and (3) the inner casing 204 is embedded in the inner space of the outer casing 200 to be combined with the outer casing 200 (Fig. 2D) , shown in 2E). The process of the details disclosed in Figures 2A, 2B, 2C, 2D, 2E, 2F The process of Figures 2A, 2B, and 2C includes the in-mold forming technique. It is obvious that steps (1) and (2) are interchangeable, and thus such embodiment variations are also intended to be protected by the present invention. According to an embodiment, wherein the first material is polyethylene terephthalate (PET) 〇 201243651, according to an embodiment, wherein the outer casing 200 comprises a key top 200A having a first color (eg, green And a key skirt 200B, which is located around the key top 200A, is coupled to the key top 200A, and has a second color (for example, yellow), so as to constitute a two-color (green yellow two-color) combination key cap. As shown in FIG. 2A to FIG. 2B, according to an embodiment, the key top 200A and the key skirt 200B form the color of the key top 200A and the key skirt 200B on the first material by a coating method or a printing method. (such as green, yellow, respectively) pattern. The symbol corresponding to the light-transmitting region 206 in Fig. 2B is exemplified by A. 2D to 2E show the combining steps, and Figs. 2E to 2F show the cutting step, that is, the combined, light-transmitting, two-color keycap 10 can be completed. The above method of manufacturing the combined keycap is described by taking a single keycap as an example. However, it should be understood that in the mass production of the factory, for the efficiency of production and the need for automation, one button is usually used for all the keys (about 85) of a complete keyboard. Therefore, when the aforementioned production method is completed, all the key caps of a complete keyboard will be completed at one time. It is to be understood that the foregoing description is intended to be illustrative and not restrictive BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 discloses an embodiment; Figures 2A, 2B, 2C, 2D, 2E, 2F disclose an embodiment of a fabrication method.
