Portable computer comprising keyboard and coordinate input tablet hingedly connected to a main body case through a junction base having a cylindrical element defining a linear groove therethrough

A portable computer comprising:

• a keyboard;
• a main body case with two lateral sides encasing said keyboard;
• an integrated display/input device having a display and a coordinate input tablet, said display and said coordinate input tablet being overlapped;
• an upper cover encasing said integrated display/input device, said upper cover having a first face in which said integrated display/input device is exposed, and a second face which is opposite to said first face;
• a junction base disposed between said two lateral sides connecting said upper cover to said main body case;
• a first hinge mechanism rotatably coupling said upper cover to said junction base along a first axis, said first hinge mechanism being rotatable between a closed position, at which said main body case and said upper cover face each other, and an open position at which said main body case and said upper cover do not face each other;
• and
• a second hinge mechanism rotatably coupling said junction base to said main body case along a second axis perpendicular to said first axis,
• said junction base comprising a cylindrical element defining a linear groove therethrough and said upper cover connects to said junction base through a projection that connects to said second hinge within said junction base at said linear groove;
• and
• wherein relative rotation of said upper cover and said junction base changes said portable computer first closed form at which said keyboard and said integrated display/input device face each other, and a second closed form at which said upper cover overlays said keyboard to expose said integrated display/input device.

A portable computer comprising:

• a main body case having two lateral sides;
• a keyboard encased by said main body case;
• an integrated display/input device having a coordinate input tablet overlaid on a display device;
• an upper cover encasing said integrated display/input device;
• junction base means between said two lateral sides;
• first hinge means rotatably coupling said junction base means to said main body case;
• and
• second hinge means rotatably coupling said upper cover to said junction base means,
• said junction base comprising a cylindrical element defining a linear groove therethrough and said upper cover connects to said junction base through a projection that connects to said second hinge within said junction base at said linear groove;
• and
• wherein relative rotation of said upper cover and said junction base means changes said portable computer between a first closed form, at which said keyboard and said integrated display/input device face each other, and a second closed form at which said upper cover overlays said keyboard to expose said integrated display/input device.
