The first body is rotated so that a rear surface of the display unit and a rear surface of the first body are close to each other, and then the second body is rotated with respect to the first body so as to support the display unit. ## Claims ### Claim 1 A foldable computing apparatus comprising: a display unit having a touch screen; a first body rotatably disposed in an end of the display unit; a second body rotatably disposed in an end of the first body opposite to the display unit, the second body having a keyboard; and at least one cushion member disposed in another end of the second body close to the first body, an end of the least one cushion member is movable toward a rear surface of the display unit regardless of a rotation angle of the second body with respect to the first body; wherein the first body is rotated such that the rear surface of the display unit and a rear surface of the first body are close to each other, and then the second body is rotated with respect to the first body so as to support the display unit. ### Claim 2 (depends on 1) The foldable computing apparatus of claim 1, further comprising: at least one first anti-slip member disposed in the other end of the first body close to the display unit. ### Claim 3 (depends on 2) The foldable computing apparatus of claim 2, further comprising: at least one second anti-slip member disposed in an end of the second body that is opposite to the first body and will be in contact with a reference surface. ### Claim 4 (depends on 1) The foldable computing apparatus of claim 1, further comprising: at least one second anti-slip member disposed in an end of the second body that is opposite to the first body and will be in contact with a reference surface. ### Claim 5 (depends on 1) The foldable computing apparatus of claim 1, wherein the at least one cushion member comprises: a housing formed of a rubber; and a spring disposed inside the housing. ### Claim 6 (depends on 5) The foldable computing apparatus of claim 5, wherein the at least one cushion member further includes a magnet disposed above the spring inside the housing; and a magnetic material to which the magnet is attracted is disposed in the rear surface of the display unit. ### Claim 7 (depends on 1) The foldable computing apparatus of claim 1, further comprising: a first hinge unit disposed between the display unit and the first body; and a second hinge unit disposed between the first body and the second body. ### Claim 8 (depends on 7) The foldable computing apparatus of claim 7, wherein the first hinge unit allows the first body to be rotated 360 degrees with respect to the display unit; and the second hinge unit allows the second body to be rotated 180 degrees with respect to the first body. ### Claim 9 (depends on 1) The foldable computing apparatus of claim 1, further comprising: a cushion device disposed in an end of the second body that is opposite to the first body and will be in contact with a reference surface. ### Claim 10 (depends on 9) The foldable computing apparatus of claim 9, wherein at least one second anti-slip member is disposed in the cushion device. ### Claim 11 (depends on 9) The foldable computing apparatus of claim 9, wherein the cushion device comprises: a plurality of elastic members disposed in an end of the second body; and a cushion plate supported by the plurality of elastic members. ### Claim 12 (depends on 1) The foldable computing apparatus of claim 1, wherein the first body comprises a main board. ### Claim 13 (depends on 1) The foldable computing apparatus of claim 1, wherein the second body comprises a touch pad and at least one USB port. ### Claim 14 A method of erecting a display unit of a foldable computing apparatus that comprises the display unit, a first body, a second body, and at least one cushion member, the method of erecting the display unit comprising: rotating the first body with respect to the display unit such that a rear surface of the first body is close to a rear surface of the display unit on which a touch screen is not disposed; rotating the second body with respect to the first body such that an end of the second body is close to the rear surface of the display unit; and putting an exposed end of the first body and the other end of the second body on a reference surface, wherein at least one cushion member is disposed in the end of the second body close to the first body; and an end of the at least one cushion member is movable toward the rear surface of the display unit regardless of a rotation angle of the second body with respect to the first body. ### Claim 15 (depends on 14) The method of erecting a display unit of claim 14, wherein when the first body is rotated with respect to the display unit, at least one first anti-slip member disposed in an end of the first body close to the display unit is exposed. ### Claim 16 A foldable computing apparatus comprising: a display unit having a touch screen; a first body having a first end to be coupled to the display unit and to be rotatable with respect to the display unit in a range of a first maximum angle; a second body rotatably coupled to a second end of the first body opposite to the display unit and to be rotatable with respect to the first body in a range of a second maximum angle smaller than the first maximum angle, the second body having a keyboard; and at least one cushion member disposed in another end of the second body close to the first body, an end of the at least one cushion member is movable toward a rear surface of the display unit regardless of a rotation angle of the second body with respect to the first body. ### Claim 17 (depends on 16) The foldable computing apparatus of claim 16, further comprising: a first hinge unit having a first shaft connected to the display unit and a second shaft connected to the first body; and a second hinge unit having a single shaft connected between the first body and the second body. ### Claim 18 (depends on 16) The foldable computing apparatus of claim 16, further comprising: a cushion member movably disposed on the second body to contact the rear surface of the display unit opposite to the touch screen in a touch mode. ### Claim 19 (depends on 16) The foldable computing apparatus of claim 16, further comprising: an anti-slip member disposed on at least one of the first body and the second body to contact a reference surface in a touch mode.
