Electronic apparatus having a touch pad capable of providing vibrations

1. An electronic apparatus, comprising:

a chassis;

a touch-operation unit includes

a pad plate for receiving a touch-input operation from a user; and

a base plate;

a support plate, within said chassis, having a mounting face to movably mount said touch-operation unit;

a vibrator, coupled to said touch-operation unit and said support plate, generates vibrations to said touch-operation unit; and

a connector having a fixing part and a retained part, wherein said fixing part is fixed to one of said touch-operation unit and said support plate, and said retained part is movable relative to the other of said touch-operation unit and said support plate at least along one direction parallel to said mounting face of said support plate.

2. The electronic apparatus of claim 1 , wherein said connector includes a cylindrical rod having a first end at which said fixing part is located, and a second end at which said retained part is located.

3. The electronic apparatus of claim 2 , wherein the other of said touch-operation unit and said support plate includes a hole through which said cylindrical rod is inserted movably at least in said one direction, and said retained part is retained in an opening edge of said hole.

4. The electronic apparatus of claim 2 , further comprising an elastic member disposed between said retained part and said opening edge of said hole, wherein said elastic member biases said touch-operation unit in order to push said touch-operation unit against said mounting face of said support plate.

5. The electronic apparatus of claim 4 , wherein said connector and said elastic member are made of an electrical conductive material.

6. The electronic apparatus of claim 1 , wherein one of said touch-operation unit and said support plate includes a snap-engaging part that snap-engages with said fixing part of said connector.

7. The electronic apparatus of claim 1 , wherein said vibrator moves said touch-operation unit relative to said support plate along said one direction.

8. The electronic apparatus of claim 7 , further comprising a positioning part that immovably positions said touch-operation unit and said support plate in a direction parallel to said mounting face of said support plate and orthogonal to said one direction.

9. The electronic apparatus of claim 1 , wherein said vibrator includes a base part, a shape-memory alloy, and a driving part.

10. The electronic apparatus of claim 9 , wherein a contraction of said shape-memory alloy moves said touch-operation unit to generate an acceleration to give said user a sense of clicking.

11. The electronic apparatus of claim 9 , wherein said base part includes a corrugated surface.

12. The electronic apparatus of claim 11 , wherein said driving part includes a corrugated surface.

13. The electronic apparatus of claim 12 , wherein said shape-memory alloy is a corrugated plate that conforms with said corrugated surface of said base part and said corrugated surface of said driving part.

14. The electronic apparatus of claim 1 , wherein said fixing part and said retained part are flange-like disks having different diameters.

15. The electronic apparatus of claim 1 , wherein said touch-operation unit further includes a board for detecting said touch-input operation.

16. The electronic apparatus of claim 15 , wherein said board is a sensor for detecting said touch-input operation.

17. The electronic apparatus of claim 1 , further comprising a plurality of push buttons supported by said support plate.
