Therefore, the additional functions of the keyboard 130 of the present embodiment are increased. Furthermore, since the sensitivity of the first sensing area S1 and the second sensing area S1 are different, the application mode of the keyboard 130 of the present embodiment can be more varied, so that the user's operational efficiency is improved. The portable electronic device 100 of this embodiment is further described below. Please refer to Fig. 2 and Fig. 3 at the same time. Fig. 3 is a cross-sectional view showing the button group of the present invention along the section line 孓3' in Fig. 2. The arrangement of the first button 13 of the button group 139 is denser than that of the second button 13. Therefore, each of the first buttons 139a includes a protrusion i39, so that the user can easily distinguish the first button 13%. . For example, the thickness of the first button 139a of the Z-to-the 139a is the thickness T2 of the singer. The thickness T1 is greater than each of the second buttons 139b. 200949611 As shown in the second embodiment of the present invention, the touch sensor board 135 includes a plurality of first sensing units 135a and a plurality of second sensing units 135b. The first sensing units 135a are located in the first sensing area S1, and the second sensing units 135b are located in the second sensing area S2. The thickness T1 of each of the first buttons 139a of the embodiment is greater than the thickness T2 of the second buttons 139b, and the protrusion 139p is designed such that the surface of the first button 139a touched by the user is a discontinuous surface. Therefore, the first sensing unit 135a and the second sensing unit 135b are designed such that the area of each of the first sensing units 135a is larger than the area of each of the second sensing units 135b. Of course, it should be understood by those of ordinary skill in the art that the area design of the first sensing unit 135a is premised on the fact that the first sensing unit 135a can sense that the user moves the finger. In addition, please refer to FIG. 4, which shows a top view of the keyboard in FIG. 2 when assembled. In this embodiment, the sides of the first buttons 139a form an angle Θ1 with the sides of the first sensing units 135a, and the angle Θ1 is, for example, 45 degrees. The sides of the second buttons 139b form another angle Θ2 with the sides of the second sensing units 10 135b, and the angle Θ2 is, for example, 45 degrees. In this way, the uniformity of the whole of the first sensing area S1 and the second sensing area S2 can be improved, so that the quality of the sensing can be improved. Of course, as shown in Fig. 2, the button group 139 may further include a confirmation button 139c, and the confirmation button 139c is located between the first buttons 139a. In this way, when the user performs the touch function by touching the sensing board 135, the confirmation key 139c can be directly pressed to perform an action such as confirmation. In addition, the keyboard 130 may further include an elastic member 133 disposed between the printed circuit board 131 200949611 and the touch sensing board 135 for providing a buffering force. Referring to Figure 5, there is shown a cross-sectional view of the keyboard along section line 5-5' of Figure 4, in accordance with an embodiment of the present invention. The portable electronic device 100 further includes a light source 150 disposed in the device body 110 (shown in FIG. 1) and located on one side of the light guiding film 137. In the embodiment, the light guiding film 137 is, for example, a transparent material. Thus, when the brightness of the environment is insufficient, the light source 150 can provide light to facilitate the user to operate the keyboard 130 of the portable electronic device. φ The following uses an example to illustrate the application of the portable electronic device of the present embodiment. When the user wants to enlarge a partial area of a picture, and the partial area is located at the corner of the picture, the user can slide the finger on the surface of the second button 139b corresponding to the second sensing area S2, so that the portable electronic device The cursor in the screen of 100 moves to the local area. At this time, the user moves the finger clockwise or counterclockwise on the surface of the first button 139a corresponding to the first sensing area S1 to enlarge the partial area of the picture. The confirmation key 139c can be used to conveniently confirm the selected 10 option when a menu appears. Of course, the application mode of the portable electronic device of the present embodiment is not limited thereto. When the user takes a picture with the portable electronic device 100, the user can also use the first sensing area 135a of the touch sensing board 135. Adjust the focus. The keyboard disclosed in the above embodiments of the present invention and the portable electronic device using the same are provided with a touch sensing board to enable the keyboard to simultaneously have the functions of touch and pressing. In addition, the touch sensing board has two sensing areas with different sensitivities, so that the operational flexibility of the portable electronic device of the embodiment is high, and the convenience is improved at the same time. In view of the above, the present invention has been disclosed in a preferred embodiment, and is not intended to limit the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
