Description of the Invention: [Technical Field] The present invention relates to a keyboard, and more particularly to a keyboard that provides both soft and hard touch. [Prior Art] Referring to Fig. 1, a conventional button structure 1 is mainly composed of a circuit board 10 and a button assembly 20. The button assembly 20 includes a plurality of button bodies 21 and a plurality of studs 22. Each of the studs 22 corresponds to each of the button bodies 21, and each of the studs 22 is located below each of the corresponding button bodies 21. Theoretically, when the button body 21 is pressed, the stud 22 located below it presses the circuit board 10, thereby outputting a corresponding signal. However, since the entire button assembly 20 is usually made of a soft material, the force of the user pressing the button body 21 is often offset by the deformation of the entire button assembly 20, which may cause the stud 22 to be insufficiently displaced. It is indeed pressed against the circuit board 10. Therefore, the user often has to re-press the button body 21, which causes inconvenience in use, which is more apparent for the button body of the double key. In view of the above, it is an object of the present invention to provide a keyboard that simultaneously provides a soft touch and rigidity during operation. SUMMARY OF THE INVENTION The present invention basically employs the features detailed below in order to solve the above problems. That is, the present invention includes a bottom plate; a thin film circuit board disposed on the bottom plate and having a switch; a key cap disposed on the 0798-A22086TWF (N2); C07017; HAWDONG 5 1326460 溥 film circuit board Above, and made of an elastic material, wherein the key cap has a moving column, and the operating column corresponds to the switch; and a reinforcing piece is disposed on the key cap and the thin film circuit board The hardness of the reinforcing sheet is greater than the hardness of the keycap. In the same manner, according to the keyboard of the present invention, the keycap is made of rubber. Also in the present invention, the reinforcing sheet comprises a rigid plastic. Also in the present invention, the rigid plastic is made of PET. Also in the present invention, the reinforcing sheet comprises a metal foil. Further, in the present invention, the reinforcing sheet has a hole, and the moving column penetrates the hole. In the present invention, the reinforcing sheet is adhered to the keycap. Further, in the present invention, the reinforcing sheet is formed by immersing in a (-"- illusive manner with the keycap. In order to make the above objects, features and advantages of the present invention more apparent, the following is preferred. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiment of the present invention will be described with reference to the drawings. Referring to FIG. 2A and f 2B gj, the keyboard 2 of the present embodiment mainly includes a bottom plate. 210, a thin film circuit board 220, a plurality of key caps 231, a plurality of key caps 232 (for convenience, the second and second FIG. 2 shows only the keycap 232) and a reinforcing film 24". The board 220 is disposed on the bottom plate 21〇, and the film circuit board 220 has a plurality of switches 221. The key heads 23 and 232 are disposed on the film circuit board 22〇, and

The value of the keycap 232 is representative of the multiple keycap (for example, the Enter keycap button,

In other words, the towel I, the size is larger than the size of the keycap 231. In addition, each of the keys = 232 has a plurality of actuators 231a, and the keycap 232 has a header 231a. The number of the moving columns of the plurality of switches 22ι on the thin film circuit board are respectively corresponding to the positions and numbers of the plurality of moving columns 2 and the plurality of moving columns 2 on the key cap 231, For the keycap: the moving column 231a and each of the moving columns 232a are respectively G and = % for each of the switches 221. The reinforcing sheet 240 is disposed between the keycap 232 (multiple keycap) and the film strip 22〇, and the reinforcing sheet 240 has a plurality of holes 241 (e.g., the second eight reverse = no). The plurality of actuating bars 23 of the keycap 232 (multiple keycaps) are a plurality of holes 241 of the sub-reinforcement piece 240. In particular, the hardness of the reinforcing sheet 24 乃 is greater than the hardness of the key cap 232 (multiple keycap). For example, the patch 240 may be made of a rigid plastic (for example, PET) or a metal foil, so that the hardness of the reinforcing sheet 240 is greater than that of the rubber cap 232 ( The hardness of the multiple keycap). In addition, the reinforcing sheet 24 can be affixed to the key towel 232 (multiple keycap) or injected into the outer chamber (i hall mode and the key cap 232 (multiple keycap). When the user presses the key cap 232 (Multiple key towel m, key cap 232 (multiple: 曰中目) and reinforcing film 240 will move toward the thin circuit board 22 (), so that the key column 232 (multiple keycap) on the moving column 2 Like the pressure-sensitive thin film circuit board 0798-A22086TWF (N2); C07 〇] 7; the switch 221 on the HAWDONG 7 1326460 220, thereby causing the keyboard 200 to output a signal corresponding to the keycap 232 (multiple keycap). As described above, Since the rubber-made keycap 232 (multiple keycap) and the reinforcing sheet 240 are combined to have an increased rigidity, when the user presses the keycap 232 (multiple keycap), it can feel soft and hard at the same time. In addition, since the rubber-made keycap 232 (multiple keycap) and the reinforcing sheet 240 are combined to have an increased rigidity, when the user presses the keycap 232 (multiple keycap) The switch 221 on the thin film circuit board 220 can be surely pressed, thereby reducing the operational inconvenience. The reinforcing sheet 240 is disposed between the keycap 232 (multiple keycap) and the thin film circuit board 220, so that the rigidity is improved without affecting the appearance of the keyboard 200. Although the present invention has been disclosed in the preferred embodiment However, it is not intended to limit the invention, and any person skilled in the art can make some modifications and refinements without departing from the spirit and scope of the invention. The scope defined by the patent scope shall prevail.
