       FIG. 4  is a diagram schematically illustrating an electronic device according to one embodiment of the disclosure.  FIG. 5  is a diagram schematically illustrating the display of  FIG. 4  is opened relatively to the main body. Referring to  FIG. 4  and  FIG. 5 , the electronic device  100  of this embodiment includes a main body  110 , a display  120 , and two support arms  130 . Due to the viewing angle in the diagram, only one support arm  130  is showing and another support arm is covered by the support arm  130  in the diagram. 
     The electronic device  100  is, for example, a sliding-type handheld electronic device that combines tablet PC (display  120 ) and an input module (main body  110 ) together. The main body  110  may include a keyboard  112 , and the display  120  includes a display surface  124 , such that users are allowed to operate the electronic device  100  by the keyboard  112  and view the image displayed on the display surface  124 . The display  120  described can be a touch display. In addition, in other embodiments, the main body  110  may further include one other touch display part that allows inputs from users. However, the disclosure is not limited thereto. 
     In an embodiment, the main body  110  includes a positioning portion  116 . Each of the support anus  130  includes a first end  132  and a second end  134 . Each first end  132  is pivoted to the main body  110 . Each of two edges of the display  120  is connected to the two second ends  134  of the support arms  130  respectively. In the embodiment, the support arms  130  have an expandable and retractable design. In other words, the lengths of the support arms  130  can be adjusted by the expandable and retractable design.  FIG. 4  depicts the closed state of the electronic device  100 . When the display  120  is opened, the display  120  slides upward until the position showing in the  FIG. 5  by the rotation of the support arms  130 , such that the electronic device  100  is opened up from the closed state to the state showing in  FIG. 5  for the user to operate. At this time, the display  120  is standing by the support of the support arms  130 , and an edge  122  of the display  120  is supported on a positioning portion  116  of the main body  110 . 
       FIG. 6  is a diagram schematically illustrating the display of  FIG. 5  is driven relatively to the main body.

In other words, the support arms  130  are expanded or retracted by the sliding relationship between the first rod  130   a  and the second rod  130   b.  In detail, the first rod  130   a  of this embodiment includes a containing portion  136  and a plurality of positioning structures  138 . A tail end  137  of the second rod  130   b  is slidably disposed within the containing portion  136 . The second rod  130   b  is adapted to be expanded or retracted at the containing portion  136  with the tail end  137  sliding along the first rod  130   a,  and each of the positioning structure  138  is adapted to position the tail end  137 . When the user adjust the display  120  by rotating it to an appropriate position, the tilting angle of the display  120  can be fixed by the positioning structures  138  which position the tail end  137 . In other embodiments, the tail end  137  of the second rod  130   b  can be positioned in the containing portions  136  by other suitable structures, and the disclosure is not limited thereto. 
       FIG. 8  is an enlarged sectional diagram schematically illustrating the main body and the display of  FIG. 5 . Referring to the  FIG. 8 , the edge  122  of the display  120  includes a protrusion  126 . The positioning portion  116  of the main body  110  includes a recess  114 . The positioning portion  116  is adapted to prevent the edge  122  from sliding along the main body  110  by the structural interference between the recess  114  and the protrusion  126 . 
     The connection manner of the support arms and display are not limited herein, and the following diagrams are used for further explanation.  FIG. 9  is a diagram schematically illustrating an electronic device according to another embodiment of the disclosure.  FIG. 10  is a diagram schematically illustrating the display of  FIG. 9  is driven relatively to the main body. Due to the viewing angle in the diagram, only one support arm  230  is showing and another support arm is covered by the support arms  230  in the diagram. Referring to  FIG. 9  and  FIG. 10 , in the electronic device  200  of this embodiment, each of two sides of the display  220  includes a sliding slot  224 . The first end  232  of the support arm  230  is pivoted to the main body  210 , and the second end  234  of the support arm  230  is slidably disposed in the sliding slot  224  of the display  220 . When the display  220  is in a position as showing in the  FIG. 9 , the electronic device  200  is in open state for the user to operate. At this time, the support arms  230  supports the display  220  to stand and an edge  222  of the display  220  is supported on the positioning portion  216  of the main body  210 . 
     When the user press the display  220 , the second end  234  of the support aim  230  moves along the sliding slot  224  to drive the display  220  to rotate from the state showing in  FIG. 6  to the state showing in  FIG. 7 , so as to adjust the tilting angle of the display  220 . In the driving process of  FIG. 6  to  FIG. 7 , the positioning portion  216  prevents the edge  222  of the display  220  from sliding along the main body  210 . 
     Thus, the design of the support arms  230  can prevent the display  220  from covering the keyboard  212  of the main body  210 , and can also prevent the relative displacement of the main body  210  and the display  220  from being too large which cause the centre of the gravity of the display  220  to be unstable, so as to enhance the convenience in use of the electronic device  200 . While attempting to put away or carry the electronic device  200 , the user can move the edge  222  of the display  220  away from the positioning portion  216  and rotate the support arms  230 , so as to drive the display  220  to rotate and close to the main body  210 . 
       FIG. 11  is an enlarged sectional diagram schematically illustrating the display and the support arm of  FIG. 9 . Referring to  FIG. 9  and  FIG. 11 , in this embodiment, the sliding slot  224  includes a plurality of positioning structures  226  therein, and each of the positioning structures  226  is adapted to position the second end  234 . When the user adjust the display  220  by rotating it to an appropriate position relative to the main body  210 , the tilting angle of the display  220  relative to the main body  210  can be fixed by the positioning structures  226  which position the second end  234 . In other embodiments, the second end  234  of the support arm  230  can be positioned in the sliding slot  224  by other suitable structures and the disclosure is not limited thereto. 
     The method of how the positioning portion prevents the edge of the display from moving along the main body is not limited herein, and the following schematics are used for further explanation.  FIG. 12  is an enlarged sectional diagram schematically illustrating an electronic device according to still another embodiment of the disclosure. Referring to  FIG. 12 , the electronic device  300  of this embodiment includes a magnetic component  340 . The magnetic component  230  is disposed at the edge  322  of the display  320 . The material of the positioning portion  316  of the main body  310  includes metals. The positioning portion  316  prevents the edge  322  of the display  320  from moving along the main body  310  by the magnetic force of the magnetic component  340  applied to the positioning portion  316 . In other embodiments, the magnetic component  340  can be disposed in the positioning portion  316 , and the material of the display  320  includes metals, such that the positioning portion  316  prevents the edge  322  of the display  320  from moving along the main body  310  by the magnetic force of the magnetic component  340  applied to the display  320 . Furthermore, two magnetic components can be disposed in the positioning portion  316  and the display  320  respectively, such that the positioning portion  316  prevents the edge  322  of the display  320  from moving along the main body  310  by the magnetic force between the two magnetic components. 
     The style of the positioning portion is not limited in the disclosure. In the  FIG. 8 , the positioning portion  116  prevents the edge  122  from sliding along the main body  210  by the structural interference between the recess  114  and the protrusion  126  of the display  120 , and this style of the design can be applied to the electronic device  200  of  FIG. 9  and  FIG. 10 . Moreover, the positioning portion  316  illustrated in the  FIG. 12  prevents the edge  322  from moving along the main body  310  by the magnetic force of the magnetic component  340 , and this style of the design can be applied to the electronic device  100  of  FIG. 5  and  FIG. 6  and the electronic device  200  of  FIG. 9  and  FIG. 10 . 
     Base on the above, in the electronic device of the embodiments of the disclosure, the length of the support arm is adjustable, the support arm is pivoted between the main body and the display (or the first end of the support arm is pivoted to the main body while the second end of the support arm is slidably disposed in the sliding slot of the display), and the positioning portion is disposed on the main body to support the display. By the expanding or retracting of the support arms (or movement by the second end of the support arms along the sliding slots), the display can be rotated to adjust the tilting angle of the display, and the positioning portion can prevent the edge of the display from moving along the main body. Thus, when the user rotate the display to adjust the tilting angle of the display, the display is prevented from covering the main body, and the relative displacement of the main body and the display is prevented from being too large which cause the centre of the gravity of the display to be unstable, so as to enhance the convenience in use of the electronic device. 
     It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the disclosed embodiments without departing from the scope of spirit of the disclosure. In view of the foregoing, it is intended that the disclosure cover modifications and variations of this disclosure provided they fall within the scope of the following claims and their equivalents.
