ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to a portable electronic device, more particularly to a portable electronic device with a concealable keyboard module.
2. Description of the Related Art
Referring to
FIG. 1
, a conventional notebook computer
100
is shown to comprise a main board module
13
and a display module
11
coupled pivotally to the main board module
13
. The display module
11
has one side that is disposed to confront the main board module
13
and that is provided with a liquid crystal display panel
15
. The main board module
13
has a top side that is disposed to confront the display panel
15
and that is provided with a keyboard module
17
and a touch control module
18
. The main board module
13
further has a bottom side
19
opposite to the top side and adapted to be disposed on a worktable.
In the conventional notebook computer
100
, because the keyboard module
17
and the touch control module
18
are present on the top side of the main board module
13
, it is not possible to install other control devices thereon. As such, the conventional notebook computer
100
is generally provided with a wide variety of connectors (not shown) to permit external connection of other control devices.
It is noted that the aforesaid drawback of the conventional notebook computer
100
is also present in conventional personal digital assistants (PDA) and conventional mobile telephone handsets.
SUMMARY OF THE INVENTION
Therefore, the main object of the present invention is to provide a portable electronic device with a concealable keyboard module, thereby resulting in extra surface space that can be to mount other control devices thereon.
According to the present invention, a portable electronic device, such as a portable computer, a personal digital assistant and a mobile telephone handset, includes a main board module having opposite first and second sides, and a keyboard module mounted on and coupled electrically to the main board module. The first side of the main board module is formed with an opening and a keyboard receiving cavity that extends from the opening toward the second side. The keyboard module is received in the keyboard receiving cavity and is capable of being pulled to extend out of the keyboard receiving cavity via the opening. As such, other control devices, such as a touch control panel and a pen input panel, can be provided on a third side of the main board module that interconnects the first and second sides.
