a controller.

7. The electronic device according to claim 1 , wherein the portable electronic device is one of the following: a mobile phone, a personal digital assistant, a communication device, a camera, a game device.

8. A hinge apparatus comprising:

at least one hinge element which comprises a first hinge half and a second hinge half,

a pivot placed on an axis of rotation in cooperative engagement with said first hinge half and said second hinge half and configured to provide that said first hinge half and said second hinge half are movable in relation to each other,

wherein the first hinge half is configured to connect to a first body part of a portable electronic device,

wherein the second hinge half is configured to connect to a second body part of said device;

wherein said first body part of the device and said second body part of the device are not directly connected to each other, and wherein said first body part and said second body part are configured to rotate about said axis of rotation, and

a shield structure configured to shield a back of said device, said shield structure movably connected to said at least one hinge element and configured to be movable in a direction perpendicular to said axis of rotation,

wherein said at least one hinge element is located on said device along said axis of rotation, between and spaced from the edges of the device.

9. The apparatus of claim 8 , wherein the hinge shield structure is connected to said pivot by a runner and a guide.

10. The hinge apparatus according to claim 8 , wherein the shield structure is connected to each hinge half of the hinge element by a runner and a guide.

11. The hinge apparatus according to claim 10 , wherein the shield structure is configured to be movable in relation to the runner connecting the hinge element to the hinge halves.
