Of course, the first button 139a can also be arranged. In the AZERTY form, the QWERTZ form or the DVORAK form. 1359369 • , %

The positions of the first button 139a and the second buttons 139b of the TW4557PA respectively correspond to the positions of the membrane switches 132. A portion of the first button 139a is located above the first sensing area S1, and a portion of the second buttons 139b are located above the second sensing area S2. In this embodiment, the arrangement of the first buttons 139a is denser than the arrangement of the second buttons 139b. That is, in the button group 139, the number of the first buttons 139a per unit area is more than the number of the second buttons 139b per unit area. By the setting of the touch sensor board 135, the user can slide the finger on the surface of the first button 139a corresponding to the first sensing area S1 and the surface of the second button 139b corresponding to the second sensing area S2, respectively. The control command is input, and the user can also input various functions corresponding to the button by pressing the first button 139a and the second button 139b. Therefore, the additional functions of the keyboard 130 of the present embodiment are increased. Moreover, 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 embodiment can be more varied, so that the user's flexibility in operation is improved. The portable electronic device 100 of this embodiment is further described below. Referring to Figures 2 and 3, FIG. 3 is a cross-sectional view of the button group taken along line 3-3' of Fig. 2, in accordance with an embodiment of the present invention. Since the arrangement of the first button 139a of the button group 139 is denser than that of the second button 139b, each of the first buttons 139a includes a protrusion 139p for allowing the user to easily distinguish the first buttons 139a. In this way, the thickness T1 of each of the first buttons 139a is greater than the thickness T2 of each of the second buttons 139b. 1359369 * , >

TW4557PA 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 to have an area 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 of 0*1 J with the sides of the first sensing units 135a and the angle Θ1 is, for example, 45 degrees. The side of each of the second buttons 139b forms a different angle Θ2 with the sides of the second sensing units 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 on the printed circuit board 131 1359369 • . . * '

Between the TW4557PA and the touch sensor board 135, it provides a buffering force. Referring to Figure 5, there is shown a cross-sectional view of the keyboard of the present invention along the section line 5-5 of Figure 1. The portable electronic device further includes a light source 150 disposed in the device body 11 (shown in FIG. 1A) and located on the 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 15 can provide light to facilitate the user to operate the disk 130 of the portable electronic device. # The following uses the example to explain the application mode of the portable electronic device of the 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 then moves the finger in a timely manner or counterclockwise on the surface of the first button 139a corresponding to the first sensing area Si to enlarge the partial area of the picture. The confirmation key 139c can be used to conveniently confirm the selected option when a menu appears. Of course, the application mode of the portable electronic device in this embodiment is not limited thereto. When the user uses the portable electronic device to take a picture, the user can also use the first sensing area of the touch sensing board 135. 135a to adjust the focus.
