Description of the Invention: [Technical Field] The present invention relates to a button module, and more particularly to a button module including a light guiding film made of a flexible light guiding material. [Prior Art] The light guiding film is a recording component of the smear group, which is used to transfer the ttj light of the button module to the age-specific surface. At present, the light guide film made of polyg (PET) or polycarbonate (PC) is often seen in the button group of the hand county. However, the polyester or polycarbonate light guide film The silky sew seam, if you want to provide a difficult silk job, you must increase the thickness of the light guide film. - So, the pressure of the button may be poor. SUMMARY OF THE INVENTION The purpose of this transcript is to provide a fiber-optic group that is made of a flexible gambling material (such as a greening material), which has good optical brightness and "human shell characteristics". Provide a good button, turn to the above _. The key module contains = I, the patent scope 'the system is exposed - a kind of button module. The button is small", the board; at least - the button is set on the board To the film. The money board is used to provide the light source; and the light guide is placed on the circuit board. The light source leads to the button. ^间' is provided by the light-emitting element, and the material of the light-guiding film is a flexible light guide material 201001465. [Embodiment] Some terms are used in the specification and subsequent claims to refer to the elements of the feature. Those of ordinary skill in the art should understand that a hardware manufacturer may refer to the same component by a different noun. This specification and subsequent applications The scope of patents does not use the difference in name as a means of distinguishing between components, but rather as a criterion for distinguishing between functional differences of components. The term "including" as used throughout the specification and subsequent claims is an open term and should be interpreted as "including but not limited to". Fig. 1 is a schematic view showing the structure of an embodiment of the button module 1 of the present invention. As shown in FIG. 1 , the button module 100 includes a circuit board 11 〇, a plurality of buttons 120-1, 120-2, 120-3, a plurality of elastic structures ^, 13 〇 2, 130-3, and a plurality of A light-emitting element 14A and a light-guiding film 15A. The keys mod~120-3 elastic structures 130-1~130-3 and the light-emitting elements 14A are disposed on the circuit board 110, and the elastic structure system respectively corresponds to the keys uoq 120 3 g-known keys ΐ2〇_ι~i2 When the 〇_3 is pressed, the elastic structure body is used to provide a corresponding button-press pressure feeling; the light-emitting element 14 is used to provide a light source; the light guiding film 150 is disposed on the button 12 (M~12) 〇_3 and the elastic structures 130-1~13〇_3, and covering the surface of the elastic structure, for guiding the light source provided by the light-emitting element 140 to the button 12 (M~12〇_3, The material of the light guiding film 150 is a flexible light guiding material (flexiblelight 7 201001465 gUldemat. The following description will be made on the button module (10). In this embodiment, the system is set up. In the case of a handheld device (for example, a mobile phone), this is not a limitation of the present invention. As described above, the material of the thin guide w is a flexible light guiding material, and the direct hardness (Sh〇rehard) is Above 45, the tensile strength is greater than Μ·Pascal (Pa). In this implementation, the flexible light guiding material system For the Wei hua character (smc〇necompound), the Xiao's hardness is between 5〇 and 75 (for example, mouth: 60), and the tensile strength is between (4) 6 and 8*1〇6 Pascal ( For example, (10) Paspu, she knows the brain, and the Weihuan scale is about 5.5 times the fineness of the polycarbon sense of the same thickness. Please refer to the && and &Fig. 3 and Fig. 2a Figure 2b shows the appearance of the button module using polycarbonate light guide film and Shihe oxygen compound light guide film. The third picture shows the button mode of the polycarbonate film and Wei compound light guide film. The luminance value of the group at different key positions 'is known from the 2a, 2b and 3rd pictures. 'Wei compound guides her to the fineness of the polycarbonate guide, and the soft properties of the Wei compound can improve the use of poly 1«The shortcomings of the carbonic acid wire pass test key and poor pressure feel: In addition, the production method of the Shixi oxygen compound light guide film is very much, for example, Shi Xi oxygen = (10) light film can be taken liquid Manufacture by injection, coating or composite molding: At the same time, the 'multi-Tt manufacturing method can make other components in the button module (for example: The design of the optical microstructure is more flexible. Please note that in the above embodiment, the material of the light guiding film 15 is used for the oxidation of 201001465, which is not a limitation of the present invention, and the quality can be adopted according to the design requirements. However, this is merely an example to illustrate the flexible light-guiding material of the light-guiding film 15 in other embodiments. Note that in the above embodiment, the Xiao film hardness of the light film 15 is Between 50 and 75 'the tensile strength of the guide 15Q _ between (four) 6 to 8 * ' ska between 'fine, this is only used as a description, and the yang of the invention's implementation The light-shielding film has a Shore hardness greater than Μ, and its tensile strength is greater than 5 5 (four) 6 Pascals, all of which are within the scope of the present invention. In the above embodiment, the button module includes the elastic structure Pt~ purchased, and the thin one is only used for the wire example, and is not the invention of the present invention. The button module may not include Any flexible road board! Γ 'In the above-mentioned real customs towel, the bribe light component (10) is set in the electric syllabus. However, this is only used as an example. It is not for the purpose of this...only a plurality of illuminating elements can be separately set. On both sides of the board. The present invention is described in the preferred embodiment of the present invention, and it should be within the scope of the present invention to modify and modify the patents according to the present invention.
