Abstract

This portable electronic device includes a covering member made of a wood piece which has been strengthened.

Claims

1. A portable electronic device which is operated while being held in a hand of a user comprising a covering member made of a wood piece which has been strengthened.

2. An electronic device according to claim 1, wherein the wood piece is strengthened by compression.

3. An electronic device according to claim 2, wherein the wood piece is compressed after a high density portion of the wood piece has been made thin and a low density portion of the wood piece has been made thick.

4. An electronic device according to claim 2, wherein the wood piece is compressed after a portion of the wood piece at which high strength must be ensured has been made thicker than a surrounding portion thereof.

5. An electronic device according to claim 2, wherein the wood piece is compressed after another wood piece has been adhered to a portion of the wood piece at which high strength must be ensured.

6. An electronic device according to claim 5, wherein the direction of the grain of the wood piece and the direction of the grain of the another wood piece are different.

7. An electronic device according to claim 2, further comprising another member which is harder than the wood piece and is disposed on a portion of the wood piece at which high strength must be ensured,

wherein, the wood piece is compressed together with the another member.

8. An electronic device according to claim 1, wherein the wood piece is strengthened by being integrated with a reinforcing member which is harder than the wood piece, in such a manner that the wood piece is superimposed upon the reinforcing member and is compressed therewith.

9. An electronic device according to claim 8, wherein the reinforcing member is of metal.

10. An electronic device according to claim 8, wherein the direction along which the reinforcing member extends and the direction of the grain of the wood piece cross one another.

11. An electronic device according to claim 8, wherein the reinforcing member is made in the form of a grating or a net.

12. An electronic device according to claim 9, wherein the reinforcing member is quenched.

13. An electronic device according to claim 1, wherein the wood piece is cut across its grain, and a synthetic resin is impregnated into a end surface of the wood piece which is formed by this cutting.

14. An electronic device according to claim 1, wherein the wood piece is strengthened by being impregnated with a synthetic resin.

15. An electronic device according to claim 1, wherein a carbonized layer is formed on a surface of the wood piece.
