According to the embodiment, wherein the first material is polyparaben ethylene glycol vinegar (PET), according to an embodiment, wherein the outer casing comprises a key top having a first color; and the 〆 key skirt is located The top of the key top is connected to the top of the key, and has a second color 'to form a two-color keycap. According to the embodiment, wherein the second material is a transparent material, the outer casing has a light transmissive region for light to pass therethrough. According to an embodiment, the outer casing is formed by an in-mold forming technique. The manufacturing method according to an embodiment of the present invention comprises: 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 first material; An inner casing is formed in a thin plate cylindrical shape, and 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, the first material is polyethylene terephthalate (PET). According to an embodiment, wherein the outer casing comprises a key top having a first color; and a key skirt having a second color to form a two-color keycap. In an embodiment, the pattern or color of the key top, the key is formed in the first material by a coating method or a printing method. Other detailed features and details of the present invention are apparent from the description of the following embodiments and the scope of the claims. [Embodiment] Referring to FIG. 1, an embodiment of a combined keycap assembly includes an outer casing 101 made of a first material, which is slightly tubular in shape, and has a tubular shape. The inner space; and an inner casing 103' of a second material is formed in a thin plate cylindrical shape, and the inner casing 103 is embedded in the inner space to be combined with the outer casing M413952 101 to form a combined keycap 1 . According to an embodiment, the first material is polyethylene terephthalate (PET). The first material can be a transparent material. According to an embodiment, the outer casing 1〇1 includes a key top 101A having a first color; and a key skirt 101B located around the key top i〇iA to be coupled to the key top 101A. There is a second color so as to form a two-color modular keycap 10. According to an embodiment, wherein the second material is a transparent material, the outer casing 1〇1 has a light transmissive region 105 for passing light through the inner casing 1〇3 and the light transmissive region 105. The light-transmissive area 105 corresponds to the function of the keycap, for example, a delete key. The outline of the light-transmitting area 105 is displayed as "delete", and so on. When the back panel of the keyboard is arranged with an LED 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 ways to make the outer casing 1 , 1, and according to an embodiment, the peripheral body 1 〇 1 error is made by an in-core molding technique (In Mold For mi ng-IMF). This IMF method is a well-known plastic molding technique. The above is a description of the two-color combined keycap, and the following is a summary of the manufacturing method. The fabrication method can be fully understood with the drawings 2A, 2B, 2C, 2D, 2E, 2F. An embodiment of the method for fabricating the keycap includes: (1) forming an outer casing 200 by an in-mold forming technique, the outer casing 200 being slightly tubular in shape, the film having an inner space and an outer casing 200 is composed of a first material (as shown in FIG. 2C); (2) an inner casing 204 is formed which is slightly thin cylindrical, and the inner casing 204 is composed of a first material, and (3) The inner casing 204 is embedded in the inner space of the outer casing 2' to be combined with the outer casing 200 (as shown in Figs. 2D, 2E). The process of the details disclosed in Figures 2A, 2B, 2C, 2D, 2E, 2F is shown. The process of Figures 2A, 2B, 2C includes the in-mold forming technique. Obviously, steps (1) and (2) are interchangeable, so such embodiment changes are also intended to be protected by the present invention. According to an embodiment, wherein the first material is polyethylene terephthalate 5 M413952 (PET) ° 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.
