Patent ID: 8457694

Claim:
A mobile communication terminal, comprising: a plurality of side keys for inputting data; a body having at least one curved or stepped side surface and a curved or stepped mounting space for mounting the side keys under the side surface; a flexible printed circuit for electrically connecting the plurality of side keys to the mobile communication terminal and comprising at least one bending portion; a plurality of back plates, wherein each back plate corresponds to at least one of the plurality of side keys for supporting the at least one of the plurality of side keys within the curved or stepped mounting space the plurality of side keys are mounted in; and a rib for structurally supporting the at least one of the plurality of side keys within the curved or stepped mounting space, wherein the rib comprises at least one bending portion facilitating a shape of the rib to conform with the shape of the curved or stepped mounting space, and wherein each of the at least one bending portion of the rib respectively corresponds with each of the at least one bending portion of the flexible printed circuit, wherein the flexible printed circuit and the rib are positioned adjacent to each other within the curved or stepped mounting space so that each of the at least one bending portion of the rib is adjacent to the respectively corresponding bending portion of the flexible printed circuit, wherein the flexible printed circuit connects the plurality of back plates to each other by attaching to a surface of the back plates and wherein the at least one bending portion of the flexible printed circuit is positioned between the back plates.
