Abstract

A power generation device including a rotation member rotatable by an operation force and a supporting member supporting the rotation member by attracting the rotation member with a magnetic force, the power generation device inducing a current to a coil by a magnetic flux of a magnet caused by rotation of the rotation member, and where, when the operation force is applied in a first state in which the rotation member is supported by the supporting member by being attracted to a first and second portions of the supporting member at respective first and second positions, the rotation member transitions to a second state by rotating with the first position of the supporting member as a first supporting point, and further transitions to a third state by rotating with a position of the supporting member different from the first position as a second supporting point.

First claim

What is claimed is:

1. A power generation device comprising:
a rotation member configured to rotate with a predetermined position as a supporting point by an externally applied operation force; and
a supporting member configured to support the rotation member by attracting the rotation member with a magnetic force exerted at a predetermined portion of the supporting member,
wherein the power generation device is configured to induce a current to a coil by causing a magnetic flux of a permanent magnet passing through the coil to fluctuate in cooperation with the rotation of the rotation member, and
wherein when the operation force is applied in a first state in which the rotation member is supported by the supporting member by being attracted to a first portion and to a second portion of the supporting member at a first position and a second position, the rotation member transitions to a second state by rotating with the first position of the supporting member as a first supporting point, and further transitions to a third state by rotating with a position of the supporting member different from the first position as a second supporting point.

2. The power generation device according to claim 1 , wherein
when supported by the supporting member with a space provided between the rotation member and a position to become the second supporting point in the first state, the rotation member rotates with the first position as the first supporting point, and then rotates with the position different from the first position as the second supporting point, and
by the rotation, the rotation member transitions to the second state by acting the operation force on the second position in the first state, and then transitions to the third state by acting the operation force on the first position.

3. The power generation device according to claim 2 , wherein
when the rotation member further rotates in the third state, the rotation member further transitions to a fourth state in which the rotation member is supported by the supporting member by being attracted to a third portion and a fourth portion of the supporting member at a respective third position and a fourth position with a space provided between the rotation member and the position to become the second supporting point.

4. The power generation device according to claim 3 , wherein a distance from the first position to a position to apply the operation force is longer than a distance from the position to become the second supporting point to the position to apply the operation force.

5. The power generation device according to claim 4 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

6. The power generation device according to claim 3 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

7. The power generation device according to claim 2 , wherein a distance from the first position to a position to apply the operation force is longer than a distance from the position to become the second supporting point to the position to apply the operation force.

8. The power generation device according to claim 7 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

9. The power generation device according to claim 2 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

10. The power generation device according to claim 9 , wherein the protrusion arranged at the predetermined position of the fixing member is supported by an elastic member that exerts stress.

11. The power generation device according to claim 1 , wherein
when the rotation member further rotates in the third state, the rotation member further transitions to a fourth state in which the rotation member is supported by the supporting member by being attracted to a third portion and a fourth portion of the supporting member at a respective third position and a fourth position with a space provided between the rotation member and the position to become the second supporting point.

12. The power generation device according to claim 11 , wherein a distance from the first position to a position to apply the operation force is longer than a distance from the position to become the second supporting point to the position to apply the operation force.

13. The power generation device according to claim 12 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

14. The power generation device according to claim 11 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

15. The power generation device according to claim 1 , wherein a distance from the first position to a position to apply the operation force is longer than a distance from the position to become the second supporting point to the position to apply the operation force.

16. The power generation device according to claim 15 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

17. The power generation device according to claim 1 , wherein the rotation member rotates with a protrusion as the second supporting point, the protrusion being arranged at a predetermined position of a fixing member configured to fix the supporting member.

18. The power generation device according to claim 17 , wherein the protrusion arranged at the predetermined position of the fixing member is supported by an elastic member that exerts stress.

19. A transmission device configured to transmit signals to an external device using power generated by the power generation device according to claim 1 .

20. A switching device configured to switch states of an external device, the switching device comprising:
the power generation device according to claim 1 ; and
a transmission device configured to transmit signals to an external device using power generated by the power generation device.
