The present invention includes a first body, a second body slidably connected to the first body, and a slide hinge module configured to guide a slidable movement of the second body on the first body to open the first body, the slide hinge module configured to guide a rotary movement of the second body against the first body in case of an open configuration of a partial region of the first body. ## Claims ### Claim 1 A mobile terminal comprising: a first body; a second body slidably connected to the first body; and a slide hinge module configured to: guide a slidable movement of the second body on the first body to expose the first body; and guide a rotary movement of the second body against the first body after the slidable movement is completed, wherein the slide hinge module comprises: a fixing part provided within the second body; a slide part configured to slide along the fixing part; and a pair of hinge arms having a first end portion rotatably connected to the slide part and a second end portion rotatably connected to the first body. ### Claim 2 (depends on 1) The mobile terminal of claim 1, wherein the pair of hinge arms comprises a first hinge arm configured to provide a turning force to the fixing part and a second hinge arm configured to guide a rotary movement of the fixing part. ### Claim 3 (depends on 2) The mobile terminal of claim 2, wherein the first hinge arm is provided with an elastic member to apply the turning force to a hinge shaft provided to the second end portion. ### Claim 4 (depends on 3) The mobile terminal of claim 3, wherein the elastic member comprises a torsion spring. ### Claim 5 (depends on 2) The mobile terminal of claim 2, wherein the fixing part is provided with a guide groove for guiding a slide movement of the second body in a manner of pressurizing the first end portion of each of the hinge arms toward the first body. ### Claim 6 (depends on 5) The mobile terminal of claim 5, wherein the guide groove is provided with a recess configured to engage the first end portion of the second hinge arm. ### Claim 7 (depends on 6) The mobile terminal of claim 6, wherein the recess is provided to a location at which the slide movement of the second body is completed. ### Claim 8 (depends on 6) The mobile terminal of claim 6, wherein the recess is formed in a bottom surface of the guide groove. ### Claim 9 (depends on 6) The mobile terminal of claim 6, wherein the first end portion of the second hinge arm is engaged with an inner circumference of the recess. ### Claim 10 (depends on 2) The mobile terminal of claim 2, wherein the first hinge arm and the second hinge arm are bent in directions opposite to each other of the first body. ### Claim 11 (depends on 1) The mobile terminal of claim 1, wherein lateral end portions of the fixing part are enclosed by lateral end portions of the slide part, and wherein the pair of hinge arms are connected to each lateral end portion of the slide part to correspond to each lateral end portion of the fixing part, respectively. ### Claim 12 (depends on 11) The mobile terminal of claim 11, further comprising a connecting rod connected to a second end portion of a second hinge arm, among the pair of hinge arms, and wherein an actuator configured to provide the turning force to the second hinge arm is loaded on the connecting rod. ### Claim 13 (depends on 1) The mobile terminal of claim 1, wherein a first display is provided to the first body to be exposed when the second body is slid relative to the first body, wherein a second display is provided to the second body to be externally exposed, and wherein after a rotary movement of the second body has been completed against the first body, the first display and the second display are coplanar. ### Claim 14 (depends on 1) The mobile terminal of claim 1, wherein a keypad is provided to the first body to be externally exposed when the second body is slid relative to the first body, wherein a display is provided to the second body to be externally exposed, and wherein after a rotary movement of the second body has been completed against the first body, the keypad and the display are coplanar. ### Claim 15 A mobile comprising: a main body provided with a first display; a slide body slidably provided to the main body to expose the first display, the slide body provided with an second display; and a slide hinge module configured to guide a slide movement of the slide body to reduce an amount of overlap between the main body and the slide body, the slide hinge module configured to guide a rotary movement of the slide body to prevent the main body and the slide body from being overlapped with each other; wherein the slide hinge module comprises: a fixing part provided within the slide body; a slide part to slide along the fixing part; and a pair of hinge arms having a first end portion rotatably provided to the slide part and a second end portion rotatably provided within the main body. ### Claim 16 (depends on 15) The mobile terminal of claim 15, wherein the rotary movement of the second slide body starts after the slide movement of the second slide body has been completed. ### Claim 17 (depends on 16) The mobile terminal of claim 16, wherein the first display and the second display are coplanar after the rotary movement of the second slide body has been completed. ### Claim 18 (depends on 15) The mobile terminal of claim 15, wherein a pair of the hinge arms comprise a first hinge arm configured to provide a turning force to the fixing part and a second hinge arm configured to guide a rotary movement of the fixing part.
