Electronic device
Disclosed is an electronic device in which a multi joint hinge, which couples a door of the electronic device, is applied. The electronic device includes a main body having a storage space therein, a door configured to open and close the storage space, and a hinge coupled to the door and the main body in order to rotate the door with respect to the main body. The hinge includes a first bracket supported by the main body, a second bracket supported by the door, a link rotatably coupled between the first bracket and the second bracket, a resilient member provided on the link and having an elasticity; a cam provided on the second bracket and formed in a shape to contact with the resilient member, so that according to a rotation direction of the door, the elasticity of the resilient member acts as an opening force or a closing force of the door, and a cam stopper integrally formed with the second bracket to prevent the cam from being moved by the elasticity of the resilient member.
