It takes not only high quality but also great convenience for electronic products to stand out among competition. All kinds of electronic products have become necessities either in people's daily life or at work while the wireless LANs are fast established.

[0003] The market of high-tech products today is the one with intense competition, and computers are most welcomed among all of the high-tech products. There's a kind of computer called “Ultra-mobile PC” (UMPC for short) featured compactness, portability and capability of processing information. The size of the UMPC is between those of a personal digital assistant (PDA for short) and a notebook, and it combines the functions of PDA, personal mobile player and digital walkman as well as provides the same operating system as the notebook does. Owing to its compactness and all of the additional features constantly developed, the UMPC has become one of the new products widely noticed.

[0004] Please refer to FIG. 1, a conventional UMPC comprises a main body 10 and a base 11, wherein a touch screen 100 is embedded on the front side of the main body 10, at both sides of the touch screen 100 of the main body 10 are plurality of control buttons 101 for users to control and operate UMPC 1, and the main body 10 is pivotally coupled to the base 11 to stand on the desk or other plane surface. Such UMPC 1 typically utilizes the touch screen 100 for input of data or command, but an external keyboard 13 may be connected to UMPC 1 to facilitate the data input.

[0005] However, there exist defects contrary to the product features of such conventional UMPC 1. First, to enhance the speed of input, users are required to buy an extra keyboard 13, but most of the users intend to buy multi-functional and user-friendly electronic products with a reasonable price. Second, the main body 10 must be pivotally coupled to the base 11 to stand on the desk or other plane surface, which makes the components of the UMPC 1 more complicated and increases the thick of it substantially as well. Besides, it is also inconvenient for users to carry the UMPC 1 and keyboard 13 at the same time. Thus, the UMPC 1 will be more competitive if the defects stated above are improved.

[0006] For the purpose of solving the defects of using, placing and carrying said UMPC, after hark work of research and experiments for a long time, the inventor has developed a portable electronic apparatus having an extendable keyboard of the present invention.

Besides, the portable electronic apparatus further comprises a keyboard and two sliding parts, wherein the keyboard is disposed between both sides of the storage slot and a plurality of buttons are disposed on one side of the keyboard. One end of each sliding part is pivotally coupled to one side of the keyboard respectively while the other end of each sliding part extends towards one side of the storage slot and slidably coupled to the corresponding side of the storage slot respectively. Said plurality of buttons are exposed out of the storage slot while the sliding parts slide to positions corresponding to the first limit part, and the keyboard may be turned towards a top side of the main body while the sliding parts slide to positions corresponding to the second limit part. Thereby, the problems of using, placing and carrying conventional keyboard would be solved.

[0014] Please refer to FIG. 2, the present invention is a portable electronic apparatus having an extendable keyboard which comprises a main body 2, a keyboard 22 and two sliding parts 23. A storage slot 21 extends inwardly at a front edge 20 of the main body 2, and a first limit part 211 is disposed at both sides of the storage slot 21 near the front edge 20 of the main body 2 while a second limit part 213 is disposed at both sides of the storage slot 21 between the first limit part 211 and the front edge 20 of the main body 2. The keyboard 22 is disposed between both sides of the storage slot 21 and a plurality of buttons 220 are disposed at one side of the keyboard 22. The sliding parts 23 are disposed between the keyboard 22 and both sides of the storage slot 21 respectively, and one end of each sliding part 23 is pivotally coupled to one side of the keyboard 22 while the other end of each sliding part 23 extends towards one side of the storage slot 21 and is slidably coupled to the corresponding side of the storage slot 21 for the keyboard 22 to slide into or out of the storage slot 21.

[0015] Please refer to FIG. 3, when two sliding parts 23 slide to the locations which correspond to the first limit part 211, said plurality of buttons will slide out of the storage slot 21 for users to input data or commands. Please refer to FIG. 4, sliding the two sliding parts 23 to the locations which correspond to the second limit part 213 would allow the keyboard 23 to be turned towards a top side of the main body 2, thus enabling users to input data or commands with the keyboard 22 while standing the main body 2 on the plane surface. Thereby, the problems of using, placing and carrying conventional keyboard would be solved and the space occupied by the conventional keyboard would be saved.
