BACKGROUND 
     1. Technical Field 
     The present invention generally relates to a portable electronic device, more specifically, relates to a portable electronic device including a camera module. 
     2. Discussion of Related Art 
     Camera modules are widely employed in various portable electronic devices such as mobile phones, smart phones, and personal digital assistants. Take mobile phones as an example, a camera module is generally installed on a rear cover of a mobile phone and an optical axis of the lens in the camera module is perpendicular to the rear side. A view captured by the camera module can be easily viewed from a screen installed on a front cover of the mobile phone. 
     With progress of technology, resolution and functions of camera modules have improved. In order to meet the increasing requirements of camera modules, more and more lenses are employed in a single camera module, which results in increasing dimensions of the camera module, which unfortunately means it is becoming more difficult to further miniaturize mobile phones using such camera modules. 
     Therefore, there is a desire to provide a thin portable electronic device including a high resolution camera module. 
     SUMMARY 
     In one exemplary embodiment, a portable electronic device includes a housing including an opening defined in a peripheral side surface thereof, a camera module mounted in the housing, and a light-reflecting member rotatably mounted at the opening. The camera module is aligned with and faces toward the opening. The light-reflecting member mounted at the opening and is configured for reflecting light into the camera module.

     DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS 
       FIG. 1  illustrates a portable electronic device  100  in accordance with a first embodiment that includes a housing  10 , a light-reflecting member  13 , a camera module  14 , and a driving member  15 . An opening  103  is formed in a peripheral side surface of the housing  10 . The camera module  14  is mounted in the housing  10  opposite to the opening  103 . The light reflecting member  13  is rotatably disposed adjacent to an edge of the opening  103 . The driving member  15  is rotatably received in a receiving hole defined in a sidewall of the housing  10 . The driving member  15  is non-rotatably engaged with the light reflecting member  13  such that the light reflecting member  13  can be rotated by driving the driving member  15 . 
     Referring to  FIG. 2 , the housing  10  includes a first housing member  11  and a second housing member  1   2 . The first housing member  11  includes a rectangular shaped bottom plate  110 . Four adjoining sidewalls extend from four sides of the rectangular shaped bottom plate  110  respectively. Each sidewall is perpendicular to the bottom plate  110 . The four sidewalls include a first sidewall  111  and a second sidewall  112  adjacent to the first sidewall  111 . A cutout  113  is formed in the first sidewall  111 . A slit  118  is formed in the second sidewall  112 . The slit  118  is adjacent to the first sidewall  111 . 
     A first protrusion  114   a , a second protrusion  115   a , and a protruding wall  119  extend from the bottom plate  110 . The first protrusion  114   a  and the second protrusion  115   a  are arranged at two ends of the cutout  113 . Each of the first protrusion  114   a  and the second protrusion  115   a  adjoins the first sidewall  111 . The protruding wall  119  defines a receiving space  113   a  adjoining the cutout  113 . 
     A first groove  114  is formed in the first protrusion  114   a . A second groove  115 , a securing groove  116 , and a third groove  117  are sequentially formed in the second protrusion  115   a . The second groove  115  is adjacent to the cutout  113 , and the third groove  117  is in communication with the slit  118 . Cross sections of the first groove  114 , the second groove  115 , the securing groove  116 , and the third groove  117  are arc shaped, preferably, semicircular shaped. The cross section area of the securing groove  116  is larger that that of the third groove  117 . 
     The second housing member  12  includes a substantially rectangular shaped front panel  120 , a first sidewall  121  and a second sidewall  122  adjoining to the first side wall  121 . A cutout  123  is formed in the first sidewall  121 . A second slit  128  is formed at an end of the second sidewall  122 . The second slit  128  is adjacent to the first sidewall  121 . When the first housing member  11  and the second housing member  12  are assemble together, as shown in  FIG. 1 , the first cutout  113  and the second cutout  123  cooperatively define an opening  103  in the housing  10 , and the first slit  118 , the second slit  128  cooperative define an receiving slit  108  in the housing  10 . 
     The light reflecting member  13  includes a cover  131 , a rotary shaft  132 , and a light reflecting mirror  133  attached to the cover  131 . The rotary shaft  132  is fixed to a side of the cover  131 . The rotary shaft  132  includes a first end  134  and a second end  135 . The second end  135  is non-circular in cross section (polygon shaped for example). 
     The driving member  15  includes a handle  151 , driving shaft  152 , and a ring shaped protrusion  153 . The handle  151  extends from a first end of the driving shaft  152 . Preferably, the handle  151  is perpendicular to the driving shaft  152 . A skidproof structure  155  is formed on the first end of the driving shaft  152 . In this embodiment, the skidproof structure  155  includes a small protrusion. A receiving hole  154  is formed at a second end of the driving shaft  152 . The receiving hole  154  extends along an axis direction of the driving shaft  152 . The receiving hole  154  is structured to mate with the second end  135  of the rotary shaft  132 . 
     When the light reflecting member  13  is assembled with the housing  10 , the first end  134  and the second end  135  of the rotary shaft  132  are received in the first groove  114  and the second groove  115  respectively, the light reflecting member  13  is thereby rotatably mounted in the housing  10 . The driving shaft  152  is received in the second groove  115 , the securing groove  116  and the third groove  117  and the ring shaped protrusion  153  is received the securing groove  116 . Furthermore, a length of the securing groove  116  is larger than a length of the ring shaped protrusion  153 ; therefore, the driving shaft  152  is rotatably and telescopically disposed in the housing  10 . The second end  135  of the rotary shaft is received in the receiving hole  154  of the driving shaft  152 ; as a result, the light reflecting member  13  can be rotated by driving the driving member  15 . When the first housing member  11  and the second housing member  12  are assembled together, the light reflecting member  13  and the driving member  15  are secured between the first housing member  11  and the second housing member  12 . 
     It is understood that similar structure of the first housing member  11  can be formed in the second housing member  12 , specifically, a mirror copy of the first protrusion  114   a , the second protrusion  115   a , the protruding wall  119 , the first groove  114 , the second groove  115 , the securing groove  116 , and the third groove  117  can be formed in the second housing member  12 . In other words, the second housing member  12  includes a first protrusion  124   a , a second protrusion, a protruding wall, a first groove  124 , a second groove, a securing groove, and a third groove. When the first housing member  11  and the second housing member  12  are assembled together, the first groove  114  and the second groove  124  are combined together thereby defining a first shaft hole. Similarly, the second groove  115  and the second groove in the second housing member constitute a second shaft hole, the securing groove  116  in the first housing member and the securing groove in the second housing member constitute a securing hole, the third groove  117  and the third groove in the second housing member  12  constitute a third through hole, the receiving space  113   a  and the receiving space in the second housing member  12  constitute a receiving chamber. The first end  134  and the second end  135  of the rotary shaft  132  can be received in the first shaft hole and the second shaft hole respectively. The camera module  14  can be received in the receiving chamber. The driving shaft  152  of the driving member  15  passes through the third through hole, the securing hole, and then finally enters the second shaft hole. 
     To use of the camera module  14 , draw the driving member  15  out a little and then rotate the driving shaft  152  using the handle  151 , the rotary shaft  132  and the cover  131  rotate with the driving shaft  152  and the camera module is exposed through the opening  103 ; adjust an angle of the cover  131  such that a view you want to record is reflected into the camera module  14 . The view captured by the camera module  14  can be viewed on the screen  16 . For example, when the cover  131  is at an angle of 45 degrees, a user can take an image of himself while viewing the image on the screen  16 . It is understood that when the cover  131  is in at angle of 90 degrees, the cover  131  is fully opened and light can directly enter the camera module. 
     Referring to  FIG. 3 , when the light reflecting member  13  is closed, the driving member  15  can be pushed inwardly such that the handle  151  of the driving member  15  is received in the receiving slit  108 , as a result, the driving member  15  can&#39;t rotate freely, consequently, the light reflecting member  13  is locked. In other words, the driving member  15  also serves as a latching mechanism of the light reflecting member  13 . 
     Finally, it is to be understood that the above-described embodiments are intended to illustrate rather than limit the invention. Variations may be made to the embodiments without departing from the spirit of the invention as claimed. The above-described embodiments illustrate the scope of the invention but do not restrict the scope of the invention.
