Abstract:
An electronic device includes a main body and a table stand connected to the main body for supporting the main body. The main body comprises a positioning member. The table stand defines at least two positioning holes. The table stand is operable to rotate relative to the main body. The positioning member is operable to be selectively inserted into either one of the at least two positioning holes, such that the table stand is operable to form a corresponding predetermined angle with the main body.

BACKGROUND 
     1. Technical Field 
     The present disclosure relates to electronic devices, and particularly to an electronic device with a table stand which is adjustable to select a desirable viewing angle. 
     2. Description of Related Art 
     Some electronic devices are equipped with a support such as a table stand that swivels out from the device to support the device on a tabletop. However, most current table stands are not adjustable or not easily adjustable. That is, the table stand folds out at a predetermined angle with the electronic device. As a result, the viewing angle for different users cannot be adjusted. 
     Therefore, it is desirable to provide an electronic device having an adjustable table stand which can overcome the above-mentioned problems.

     DETAILED DESCRIPTION 
     Embodiments of the present disclosure will now be described in detail with reference to the drawings. 
     Referring to  FIG. 1 , a device  100  includes a main body  10  and a table stand  20  rotatably connected to the main body  10 . The main body  10  includes a front body  12  and a rear cover  11  covering the back of the front body  12 . In this embodiment, the device  100  is a digital photo frame. 
     Referring to  FIGS. 2-4 , the rear cover  11  includes an outer surface  120  and an inner surface  121 . The inner surface  121  faces the front body  12 , while the outer surface  120  faces away from the front body  12 . The rear cover  11  defines a rectangular space  122  and a groove  126  communicating with the space  122 . The rear cover  11  further defines an opening  123  through the outer surface  120  and the inner surface  121  and a pair of pivot holes  124  communicating with the groove  126 . The pivot holes  124  are coaxially positioned at two opposite sides of the opening  123 . The opening  123  is positioned between the pair of the pivot holes  124 . The rear cover  11  further includes two fixing columns  125  protruding from the inner surface  121  and adjacent to the opening  123 . Each of the fixing columns  125  defines a screw hole (not labeled). 
     The main body  10  further includes a fixing mechanism  13  positioned on the inner surface  121  of the rear cover  11 . The fixing mechanism  13  includes a bottom cover  132 , a top cover  131 , an elastic member  133 , a positioning member  134 , and two screws  135 . Each of the top cover  131  and the bottom cover  132  defines two through holes  138 . The top cover  131  and the bottom cover  132  are sleeved on the fixing columns  125  via the through holes  138 . The screws  135  are screwed into the fixing columns  125  to fix the top cover  131  and the bottom cover  132  on the inner surface  121 . 
     The top cover  131  and the bottom cover  132  further jointly define a first hole  136  and a second hole  137 . The second hole  137  communicates with the first hole  136  and faces the opening  123 . The elastic member  133  is received in the first hole  136 . The positioning member  134  includes a first portion  134   a  and a second portion  134   b  formed on the first portion  134   a . The first portion  134   a  is received in the first hole  136  adjacent to the second hole  137  and resists the elastic member  133 . Accordingly, the elastic member  133  applies an elastic repelling force to the positioning member  134 . The second portion  134   b  is inserted through the second hole  136  and protrudes outward from the top cover  131  and the bottom cover  132 . 
     The table stand  20  includes a supporting plate  21 , two shafts  22 , and a positioning plate  23 . The supporting plate  21  is a substantially rectangular plate having a bent end  210 . The two shafts  22  extend coaxially from two opposite sides of the bent end  210  respectively. The positioning plate  23  protrudes upward from the bent end  210  and defines a plurality of positioning holes  24 . The plurality of positioning holes  24  are substantially aligned in an arc. The table stand  20  further defines two slots  25  in the bent end  210  at opposite sides of the positioning plate  23 , such that two bendable portions  212  are formed adjacent to the two slots  25  correspondingly. The two bendable portions  212  can be flexibly pressed toward the positioning plate  23 . 
     Further referring to  FIG. 5 , the two bendable portions  212  are pressed toward the positioning plate  23 , such that the two shafts  22  move toward the positioning plate  23 . Then, the positioning plate  23  is inserted through the opening  123 , and the bent end  210  is received in the groove  126 . Finally, the two bendable portions  212  are released, such that the two shafts  22  are pivotably inserted into the two pivot holes  124 . As such, the table stand  20  is assembled to the main body  10 . 
     To provide support for the main body  10 , the table stand  20  is rotated relative to the main body  10  to a support position. If the second portion  134   b  is aligned with one of the positioning holes  24 , the second portion  134   b  is inserted into the aligned positioning hole  24  due to the repelling force of the elastic member  133 . As such, the table stand  20  is fixed and forms a predetermined angle with respect to the main body  10 . Otherwise, the second portion  134   b  is resisted by the positioning plate  23  and received in the second hole  137 . The angle between the table stand  20  and the main body  10  can be adjusted via fixing the table stand  20  at different positions corresponding to the plurality of positioning holes  24 . Thereby, the main body  10  can be placed at an appropriate viewing angle for a user. Referring to  FIG. 6 , the table stand  20  can be rotated to be received in the space  122  if the main body  10  does not need to be supported. 
     While various exemplary and preferred embodiments have been described, it is to be understood that the disclosure is not limited thereto. To the contrary, various modifications and similar arrangements (as would be apparent to those skilled in the art) are intended to also be covered. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
