       [0001]    The present application is related to and claims the benefit under 35 U.S.C. §119(a) of a Korean patent application filed on Dec. 21, 2015, in the Korean Intellectual Property Office and assigned Serial No. 10-2015-0182710, the entire disclosure of which is hereby incorporated by reference. 
       TECHNICAL FIELD 
       [0002]    Various embodiments relates to an electronic device including a coupling structure. 
       BACKGROUND 
       [0003]    Mobile devices, particularly a portable mobile device such as a notebook computer have a display unit for enabling to obtain information through visual sense and a manipulation unit for manipulating the device. The display unit and the manipulation unit may be mounted in two housings, respectively. By tilting the two housings, the manipulation unit, the display unit, or both units may be converted to a use state in which a user may use or to an idle state for movement and reception. 
         [0004]    In the notebook computer, because two housings are connected to a fixed hinge structure, the two housings may not generally be separated. Nowadays, while an individually usable tablet Personal Computer (PC) is widely used, in order to compensate an input function of the tablet PC, a method of detachably attaching the tablet PC to a housing having a manipulation unit is considered. 
       SUMMARY 
       [0005]    To address the above-discussed deficiencies, it is a primary object to provide an electronic device including a coupling structure that can use in various forms by organically connecting two detachable housings. 
         [0006]    In accordance with an embodiment of the present disclosure, an electronic device may include a first housing having a first surface and a second surface at a rear surface of the first surface that is opposite from the first surface. In various embodiments, a second housing may be coupled to the first housing, and the second housing may include a third surface, a fourth surface at a rear surface opposite of the third surface, and a side member that encloses space between the third surface and the fourth surface. The first housing may further include a coupling structure on the first surface; the coupling structure connected to a portion of the side member of the second housing, when the second housing is coupled to the first housing. Moreover, the coupling structure may include a recess extended in a first direction along a portion of the side member, when the second housing is coupled to the first housing. A moving member that performs a pivotal movement about a shaft may be extended in the first direction while the second housing is coupled to the first housing. Finally, various embodiments may include a retainer system that enables the second housing to at least partially stay within the moving member at a recess portion, when the second housing is not coupled to the first housing. 
         [0007]    An electronic device including a coupling structure, according to various embodiments of the disclosure, may reduce an amount of movement, reduce a frequency of movement, or possibly prevent the electronic device from moving by restricting a coupling structure when two detachable housings are coupled. 
         [0008]    An electronic device including a coupling structure, according to various embodiments, may be fixed in a position using a magnet, such that a number of components for assembly of the electronic device may be decreased and, hence, a cost thereof can be reduced. 
         [0009]    When an electronic device including a coupling structure according to various embodiments is coupled to a separate cover, the electronic device may be prevented from moving, or a distance of moving or frequency of moving may be reduced, by using a camera deco. The restriction of movement may cause a component number to decrease and thus may reduce a cost of making the electronic device Also, when an electronic device including a coupling structure is coupled to a separate cover using a magnet, according to various embodiments of the disclosure, a movement of the electronic device by be reduced or prevented and therefore, provide a convenience to a user thereof.

Those skilled in the art will understand that the principles of the present disclosure may be implemented in any suitably arranged electronic device. 
         [0035]    Hereinafter, various embodiments of this document will be described in detail with reference to the accompanying drawings. However, it should be understood that technology described in this document is not limited to a specific exemplary embodiment and includes various modifications, equivalents, and/or alternatives of an embodiment of this document. The same reference numbers are used throughout the drawings to refer to the same or like parts. 
         [0036]    In this document, an expression such as “have,” “may have,” “comprise,” or “may comprise” indicates existence of a corresponding characteristic (e.g., constituent element such as a numerical value, function, operation, or component) and does not exclude presence of another characteristic. 
         [0037]    In this document, an expression such as “A or B”, “at least one of A or/and B”, or “one or more of A or/and B” may include an entire combination of together listed items. For example, “A or B,” “at least one of A and B,” or “one or more of A or B” may indicate the entire of (1) a case of including at least one A, (2) a case of including at least one B, and (3) a case of including both at least one A and at least one B. 
         [0038]    An expression such as “first” and “second” used in this document may indicate various constituent elements regardless of order and/or importance, is used for distinguishing a constituent element from another constituent element and does not limit corresponding constituent elements. For example, a first user device and a second user device may represent another user device regardless of order and/or importance. For example, a first constituent element may be referred to as a second element without deviating from the scope described in this document, and similarly, a second constituent element may be referred to as a first constituent element. 
         [0039]    When it is described that a constituent element (e.g., a first constituent element) is “(operatively or communicatively) coupled with/to” or is “connected to” another constituent element (e.g., a second constituent element), it should be understood that the constituent element may be directly connected to the another constituent element or may be connected to the another constituent element through another constituent element (e.g., a third constituent element). However, when it is described that a constituent element (e.g., a first constituent element) is “directly connected” or is “directly accessed” to another constituent element (e.g., a second constituent element), it may be understood that another constituent element (e.g., a third constituent element) does not exist between the constituent element and the another constituent element.

         [0099]    According to various embodiments, at least one magnet  852  of the first coupling structure  850  may be each disposed to have the same polarity in the same direction. At least one magnet  811  included in the second coupling structure  810  may be each disposed to have the same polarity in the same direction. 
         [0100]    According to various embodiments, the polarity of at least one magnet  852  of the first coupling structure  850  and the polarity of at least one magnet  811  included in the second coupling structure  810  may be opposite. For example, when the polarity of at least one magnet  852  of the first coupling structure  850  is an N-pole, the polarity of at least one magnet  811  included in the second coupling structure  810  may be an S-pole.
