Abstract

An electronic apparatus includes a power generator including a movable portion displaced by kinetic energy acting on an electronic apparatus body and a conversion portion converting displacement of the movable portion to electric energy, wherein the movable portion of the power generator is arranged at a position separated from a support portion of the electronic apparatus body.

Claims

1. An electronic apparatus comprising:

a power generator including a movable portion displaced by kinetic energy acting on an electronic apparatus body and a conversion portion converting displacement of said movable portion to electric energy, wherein

said movable portion of said power generator is arranged at a position separated from a support portion of said electronic apparatus body.

2. The electronic apparatus according to claim 1, wherein

said support portion is arranged below said movable portion.

3. The electronic apparatus according to claim 2, wherein

said support portion is arranged below a gravity center of said electronic apparatus body.

4. The electronic apparatus according to claim 1, wherein

said electronic apparatus body is so formed as to be supported at said support portion in a used state.

5. The electronic apparatus according to claim 1, wherein

said movable portion is arranged above a gravity center of said electronic apparatus body.

6. The electronic apparatus according to claim 1, further comprising an operating portion for operation of said electronic apparatus body by a user, wherein

said movable portion is arranged on a side opposite to said operating portion with respect to a center of said electronic apparatus body.

7. The electronic apparatus according to claim 6, wherein

said movable portion is so arranged as to overlap with said operating portion in plan view.

8. The electronic apparatus according to claim 1, further comprising a display portion, wherein

said movable portion is arranged on the same side as said display portion with respect to a center of said electronic apparatus body.

9. The electronic apparatus according to claim 1, wherein

said movable portion is so formed as to linearly vibrate, and

said movable portion is so arranged as to vibrate in a direction intersecting with a long side of said electronic apparatus body.

10. The electronic apparatus according to claim 9, wherein

said movable portion is so arranged as to vibrate in a direction substantially perpendicular to said long side of said electronic apparatus body.

11. The electronic apparatus according to claim 1, wherein

said movable portion is so formed as to linearly vibrate, and

said movable portion is so arranged as to vibrate along an extensional direction of a short side of said electronic apparatus body.

12. The electronic apparatus according to claim 1, wherein

said movable portion is arranged in the vicinity of an end on a side opposite to said support portion in a long side direction of said electronic apparatus body with respect to a center of said electronic apparatus body.

13. The electronic apparatus according to claim 1, wherein

said support portion is provided with a nonslip structure.

14. The electronic apparatus according to claim 1, wherein

said power generator is so formed as to convert kinetic energy acting on said electronic apparatus body to electric energy due to electromagnetic induction by vibration of said movable portion.

15. The electronic apparatus according to claim 14, wherein

said movable portion includes a permanent magnet, and

said power generator includes a housing, said permanent magnet stored in said housing and a coil wound around said housing.

16. The electronic apparatus according to claim 1, wherein

said movable portion includes a movable electrode having an electret film, and

said power generator is so formed as to convert kinetic energy acting on said electronic apparatus body to electric energy due to electrostatic induction by vibration of said movable electrode.

17. The electronic apparatus according to claim 1, wherein

said electronic apparatus body is provided with a recess portion for placing a finger of a user in grasping by the user, arranged below said movable portion.

18. The electronic apparatus according to claim 1, wherein

said power generator is so mounted as to be detachably attached to an outer portion of said electronic apparatus body.

19. The electronic apparatus according to claim 1, wherein

said electronic apparatus body is so formed as to be foldable from an open state, and said movable portion is arranged above a gravity center of said electronic apparatus body in the open state.

20. A portable telephone comprising:

a power generator including a movable portion displaced by kinetic energy acting on an electronic apparatus body and a conversion portion converting displacement of said movable portion to electric energy, wherein

said movable portion of said power generator is arranged at a position separated from a support portion of said electronic apparatus body.
