Abstract

A portable communication apparatus has a rotary input device adapted for use by an end-user to control the portable communication apparatus. The rotary input device comprises an element which is exchangeable by the end-user.

Claims

1. A portable communication apparatus having a rotary input device adapted for use by an end-user to control the portable communication apparatus, the rotary input device comprising an element which is exchangeable by said end-user.

2. An apparatus as in claim 1, wherein said rotary input device also comprises an essentially non-exchangeable part upon which said exchangeable element is mounted.

3. An apparatus as in claim 2, further having an apparatus housing with a front surface which faces said end-user during normal operation of said apparatus, wherein said rotary input device is disposed in an opening in said front surface so that said exchangeable element is accessible to said end-user during said normal operation.

4. An apparatus as in claim 3, wherein said apparatus housing comprises an exchangeable housing part and wherein said exchangeable element is removable from said rotary input device only once said exchangeable housing part has been removed from said portable communication apparatus.

5. An apparatus as in claim 4, wherein said exchangeable element is a top ring which is rotary in a plane essentially parallel to said front surface.

6. An apparatus as in claim 5, further comprising a center key disposed inside said top ring.

7. An apparatus as in claim 6, further comprising releasable fastening means for securing said center key to said top ring and for allowing said center key to be detached from said top ring so as to permit exchange of said center key by said end-user.

8. An apparatus as in claim 7, wherein said center key is secured to said top ring by said releasable fastening means, so that said center key is removable from said top ring only once said top ring has been removed from said portable communication apparatus.

9. An apparatus as in claim 8, wherein said releasable fastening means comprises a snap locking.

10. An apparatus as in claim 5, wherein said essentially non-exchangeable part comprises a bearing module to support rotation of said top ring.

11. An apparatus as in claim 10, wherein said bearing module comprises engagement means for matching engagement with corresponding engagement means of said top ring and wherein said engagement means are such that said top ring is removable from said bearing module by said end-user.

12. An apparatus as in claim 11, wherein said engagement means of said top ring includes a plurality of protrusions disposed on a surface of said top ring, and wherein said engagement means of said bearing module includes a plurality of recesses adapted for matching engagement with said plurality of protrusions.

13. An apparatus as in claim 12, wherein said plurality of protrusions are equidistantly disposed on an inner perimeter of said top ring.

14. An apparatus as in claim 5, further comprising a set of additional keys disposed adjacently to an outer perimeter of said top ring.

15. An apparatus as in claim 14, wherein said set of additional keys form an integral key frame member which is removable from said portable communication apparatus by said end-user.

16. An apparatus as in claim 1, embodied as a mobile terminal for a telecommunications system.

17. An apparatus as in claim 16, wherein said telecommunications system is selected from the group consisting of:

GSM, UMTS, D-AMPS and CDMA2000.

18. A rotary input device for a portable communication apparatus, said rotary input device having an element which is exchangeable by an end-user of said portable communication apparatus.

19. A device as in claim 18, wherein said rotary input device also comprises an essentially non-exchangeable part upon which said exchangeable element is mounted.

20. A device as in claim 19, wherein said exchangeable element is a top ring which is rotary in a plane essentially parallel to a front surface of said portable communication apparatus.

21. A device as in claim 20, further comprising a center key disposed inside said top ring.

22. A device as in claim 21, further comprising releasable fastening means for securing said center key to said top ring and for allowing said center key to be detached from said top ring so as to permit exchange of said center key by said end-user.

23. A device as in claim 22, wherein said center key is secured to said top ring by said releasable fastening means, so that said center key is removable from said top ring only once said top ring has been removed from said portable communication apparatus.

24. A device as in claim 23, wherein said releasable fastening means comprises a snap locking.

25. A device as in claim 19, wherein said essentially non-exchangeable part comprises a bearing module to support rotation of said top ring.

26. A device as in claim 25, wherein said bearing module comprises engagement means for matching engagement with corresponding engagement means of said top ring and wherein said engagement means are such that said top ring is removable from said bearing module by said end-user.

27. A device as in claim 26, wherein said engagement means of said top ring includes a plurality of protrusions disposed on a surface of said top ring, and wherein said engagement means of said bearing module includes a plurality of recesses adapted for matching engagement with said plurality of protrusions.

28. A device as in claim 27, wherein said plurality of protrusions are equidistantly disposed on an inner perimeter of said top ring.

29. A device as in claim 28, further comprising a set of additional keys disposed adjacently to an outer perimeter of said top ring.

30. A device as in claim 29, wherein said set of additional keys form an integral key frame member which is removable from said portable communication apparatus by said end-user.

31. An exchangeable element for a rotary input device according to claim 18.
