FIELD OF THE INVENTION  
       [0001]     The present invention relates to a communication apparatus, and more particularly to a portable communication apparatus.  
       BACKGROUND OF THE INVENTION  
       [0002]     With the increasing improvement of communication techniques, the portable communication devices such as mobile phones are more and more popularized. Conventionally, it always adopts the pad input or handwriting input for inputting the information to the portable communication devices. With reference to  FIG. 1 , which schematically shows the construction of a conventional mobile phone according to the prior art, the conventional mobile phone  1  is constructed by a base portion  11 , a display  12  for showing all the function options and a pad  13  serving as the input device thereof.  
         [0003]     Moreover, please refer to  FIG. 2 , which is a flowchart illustrating the steps of a conventional input method adopted in the mobile phone according to the prior art. First, a desired function option of the mobile phone is selected, so as to enter into the phone directory constructed therein, as shown in the steps S 21  and S 22 , respectively. For editing the phone directory, the desired information is input and/or modified by means of pad input or handwriting input, as shown in the step S 23 . After the information to be input or stored in the mobile phone is recognized, the edition procedure is completed and then the user may escape from the function option regarding the phone directory, as shown in the respective steps S 24  and S 25 . No matter what kinds of input codes are adopted, it is believed inconvenient for the user to edit the information by means of pad input or handwriting input with the pad having a limited area, which makes such conventional mobile phones relatively disadvantageous.  
         [0004]     For overcoming the mentioned drawbacks of the prior art, a novel portable communication apparatus is provided. The provided portable communication apparatus is provided with an optical character recognition function, in which an optical input unit is configured for obtaining the image information. The obtained image information is transformed into text information that is recognizable for the portable communication apparatus, so as to be processed and stored therein. Moreover, the optical input unit also provides a quick operation for information input, whereby it would be more flexible and convenient to obtain any desired information for being further processed. Accordingly, the image information obtained by the optical input unit could be edited by the edition unit or editor configured in the portable communication apparatus. In comparison with the conventional portable communication apparatus whose optical input unit functions only for taking a shot, the present portable communication apparatus is provided with an enhanced function, where an optical character recognition function is achieved thereby.
