BACKGROUND 
       [0001]    1. Technical Field 
         [0002]    The present disclosure generally relates to mobile phones, and particularly to a mobile phone capable of performing as a keyboard and as a mouse. 
         [0003]    2. Description of Related Art 
         [0004]    Portable tablet personal computers (PC) have become much more popular in recent years. Some people find it difficult to input text or operations with the touch-screen of the tablet PC. However, it is inconvenient to carry around a traditional mouse and keyboard to be used with the tablet PC. 
         [0005]    Therefore, there is room for improvement in the art.

     DETAILED DESCRIPTION 
       [0011]    Reference will be made to the drawings to describe the present mobile phone, the subject of this disclosure, in detail. 
         [0012]    Referring to  FIG. 1  and  FIG. 2 , a mobile phone  1  according to an exemplary embodiment includes a main body  10 , a mouse unit  14  and a keyboard unit  16 . The main body  10  has a communication unit  102  and a bluetooth module  104  ( FIG. 3 ) arranged therein. The bluetooth module  104  is capable of communicating with the mouse unit  14 , the keyboard unit  16  and an external computer (not labeled). 
         [0013]    The main body  10  is generally cuboid. The main body  10  has a liquid crystal display (LCD) panel  15  arranged at a middle portion. The main body  10  further includes two lateral walls  12 . One of the two lateral walls  12  has a mode switch  13  arranged thereon. 
         [0014]    The mouse unit  14  is arranged at the top of the main body  10 . The mouse unit  14  includes a left mouse button  141 , a right mouse button  142  and a mouse wheel  143  between the left mouse button  141  and the right mouse button  142 . The mouse unit  14  further includes an optical sensor, an optical lens, a light emitting diode (LED) and a processor (not labeled) for performing a mouse function. The optical sensor can be a complementary metal-oxide semiconductor (CMOS) sensor. The LED can be a red LED on a bottom of the phone  1 . The processor can be a digital signal processor (DSP). 
         [0015]    When an object, or the surface of an object, is presented to the mobile phone  1 , light emitted from the LED hits the surface and bounces off that surface onto the optical sensor to form images. The optical sensor sends each image to the processor for analysis. The processor is able to detect patterns in the images and see how those patterns have moved since a previous image. Based on the change in patterns over a sequence of images, the processor is capable of determining the distance and direction the mouse unit  14  has moved and sending the corresponding coordinates to the external computer by the bluetooth module  104 . 
         [0016]    The keyboard unit  16  is arranged at the bottom of the main body  10 . The keyboard unit  16  includes a processor, a circuit board with circuitry that carries information to and from the processor, a plurality of keys  161 , and a decoder. The keyboard unit  16  includes a processor and circuitry that carries information to and from the processor. A large part of this circuitry makes up a key matrix, which is a grid of conductive lines underneath the keys  161 . Each circuit is broken at a point below each key cap. When a key cap is pressed, it completes a circuit and allows a tiny amount of current to flow through. When the processor finds a circuit which has been completed in this way, it compares the location of that circuit on the key matrix to the character map in its read-only memory (ROM). The character map is basically a comparison chart or lookup table, which has a list of each key in the matrix and what each key, or combination of keystrokes, represents. When communicating with the external computer through the bluetooth module  104 , the key board unit  16  is capable of performing as an input device to the external computer. 
         [0017]    The mode switch  13  includes a sliding portion  131 . The sliding portion  131  is capable of sliding along the lateral wall  12  where the mode switch  13  sits. Also referring to  FIG. 3 , inside of the main body  10 , a first contact “A”, a second contact “B” and a third contact “C” are arranged. The contact “A” is connected to an operating circuit of the mouse unit  14 . The contact “B” is connected to an operating circuit of the keyboard unit  16 . The contact “C” is connected to the communication unit  102 . The sliding portion  131  respectively contacts one of the three contacts at three different positions on the sliding path on the lateral wall  12 . 
         [0018]    Accordingly, the sliding portion  131  works as a switch for allowing or breaking a power supply to the operating circuit of the mouse unit  14 , the operating circuit of the keyboard unit  16 , and the communication unit  102 . 
         [0019]    When the sliding portion  131  contacts the first contact “A”, the mobile phone  1  is switched to a mouse mode, in which the mouse unit  14  is activated to work. In this condition, the mobile phone  1  can be used as a mouse. 
         [0020]    When the sliding portion  131  contacts the second contact “B”, the mobile phone  1  is switched to a keyboard mode, in which the keyboard unit  16  is activated to work. In this condition, the mobile phone  1  can be used as a keyboard. 
         [0021]    When the sliding portion  131  contacts the third contact “C”, the mobile phone  1  is switched to a communication mode, in which the communication unit  102  is activated to work. In this condition, the mobile phone  1  can be used as a normal telephone. 
         [0022]    Referring to  FIG. 4 , the mobile phone  1  can further include a shielding cover  17 . In mouse mode, the shielding cover can be moved to cover the LCD panel  15  and the keyboard  16 , thereby protecting the LCD panel  15  and the keyboard  16  from damage. In the keyboard mode and the communication mode, the shielding cover can be removed to expose the LCD panel  15  and the keyboard  16  for use. 
         [0023]    It is to be understood that the above-described embodiments are intended to illustrate rather than limit the disclosure. Variations may be made to the embodiments without departing from the spirit of the disclosure as claimed. The above-described embodiments illustrate the scope of the disclosure but do not restrict the scope of the disclosure.
