The present invention includes a body including a rear case having a front part and a rear part, a battery received in the body, a battery cover detachably provided between the front part and the rear part to protect the battery against external environment, a guide member fixed to an inner surface of one end portion of the battery cover, a moving member received in the guide member to be guided by the guide member to move in front and rear directions, and a hooking member provided within the body, the hooking member including a hooking surface engaged with the moving member to fix the battery cover to the body. ## Claims ### Claim 1 A mobile terminal comprising: a body including a rear case having a front part and a rear part; a battery received in the body; a battery cover detachably provided between the front part and the rear part to protect the battery against external environment; a guide member fixed to an inner surface of one end portion of the battery cover; a moving member received in the guide member to be guided by the guide member to move in front and rear directions; and a hooking member provided within the body, the hooking member including a hooking surface engaged with the moving member to fix the battery cover to the body. ### Claim 2 (depends on 1) The mobile terminal of claim 1, the guide member comprising: a backside portion configured to restrict a backward moving distance of the moving member; at least one opening provided to the rear portion; and a stop sill configured to restrict a rear-directional moving distance of the moving member. ### Claim 3 (depends on 2) The mobile terminal of claim 2, the moving member comprising at least one guide projection configured to penetrate the at least one guide opening provided to the guide member. ### Claim 4 (depends on 3) The mobile terminal of claim 3, further comprising an elastic member provided between the moving member and the backside portion of the guide member to be penetrated by the guide member. ### Claim 5 (depends on 1) The mobile terminal of claim 1, wherein an elastic member is provided to the body to apply an elastic restoring force to a bottom surface of the guide member. ### Claim 6 (depends on 1) The mobile terminal of claim 1, wherein a slot is formed at one end portion of the battery cover having the guide member provided thereto to detach the battery cover. ### Claim 7 (depends on 6) The mobile terminal of claim 6, the moving member comprising: a hooking sill having a hooking surface engaged with the hooking surface of the hooking member; and a push sill provided toward the inner surface of the battery cover. ### Claim 8 (depends on 7) The mobile terminal of claim 7, wherein the push sill includes a push surface configured to come in contact with a user's fingernail and wherein the push surface comprises either an inclining surface or a convex surface. ### Claim 9 (depends on 7) The mobile terminal of claim 7, wherein the hooking member includes a sliding surface extending from the hooking surface, wherein the hooking sill of the moving member includes a sliding surface extending from the hooking surface, and wherein the sliding surface comprises either an inclining surface or a convex surface. ### Claim 10 (depends on 1) The mobile terminal of claim 1, wherein an unlocking member and the hooking member are included in an inner surface of the rear part, and wherein the unlocking member has a pressurizing projection configured to deliver a pressurizing force working downward from one end portion of the rear part to the moving member. ### Claim 11 (depends on 10) The mobile terminal of claim 10, wherein a top surface of the pressurizing projection comprises either an inclining surface or a convex surface and a bottom surface of the pressurizing projection comprises either an inclining surface or a convex surface. ### Claim 12 (depends on 10) The mobile terminal of claim 10, wherein the one end portion of the rear part provided with the unlocking member is configured to elastically reciprocate at a prescribed height. ### Claim 13 (depends on 10) The mobile terminal of claim 10, wherein the hooking member is configured with ‘L’ shape and wherein the hooking member is arranged by being spaced apart from the unlocking member in rear direction by a prescribed distance. ### Claim 14 (depends on 10) The mobile terminal of claim 10, the moving member comprising: a 1st projecting portion provided to an upper portion of the moving member to receive the pressurizing force from the pressurizing projection; and a 2nd projecting portion provided to a lower portion of the moving member, the 2nd projecting portion having a hooking surface configured to be engaged with the hooking surface of the hooking member. ### Claim 15 (depends on 14) The mobile terminal of claim 14, the 1st projecting portion comprising: a pressurized surface receiving the pressurizing force from a bottom surface of the pressurizing projection; and a sliding surface extending from the pressurized surface to have a top surface of the pressurizing projection slide thereon. ### Claim 16 (depends on 1) The mobile terminal of claim 1, the moving member comprising: a 1st projecting portion configured to move the moving member in front direction by delivering a pressurizing force working in lateral direction of the battery cover to the moving member; and a 2nd projecting portion having a hooking surface configured to be engaged with the hooking surface of the hooking member. ### Claim 17 (depends on 16) The mobile terminal of claim 16, wherein the 1st projecting portion is situated in the moving member in a manner that a vertical center of the 1st projecting portion is eccentric in one direction from a vertical center of the moving member. ### Claim 18 (depends on 17) The mobile terminal of claim 17, wherein a chamfer is provided to one lateral side situated close to the vertical center of the moving member between both lateral sides of the 1st projecting portion and wherein the chamfer includes either an inclining surface or a convex surface. ### Claim 19 (depends on 17) The mobile terminal of claim 17, wherein the 2nd projecting portion is situated in the moving member at a position spaced by a prescribed distance from one lateral side situated close to the vertical center of the moving member between both lateral sides of the 1st projecting portion. ### Claim 20 (depends on 16) The mobile terminal of claim 16, wherein the 2nd projecting portion includes a sliding surface extending from the hooking surface and wherein the siding surface comprises either an inclining surface or a convex surface. ### Claim 21 (depends on 16) The mobile terminal of claim 16, wherein an unlocking member and the hooking member are provided under the rear part, and wherein the unlocking member is configured in vertical direction to move the moving member in front direction by applying the pressurizing force to the 1st projecting portion on moving the battery cover by a prescribed distance in lateral direction. ### Claim 22 (depends on 21) The mobile terminal of claim 21, wherein the unlocking member is situated by being spaced apart by a prescribed distance from a vertical center of the rear part. ### Claim 23 (depends on 21) The mobile terminal of claim 21, the hooking member comprising: a horizontal portion formed in horizontal direction from the unlocking member, the horizontal portion having an inclining or convex sliding surface on a top surface extending from the hooking surface;
