Abstract

A storage apparatus that stores objects includes a housing; a fixed part disposed in the housing and fixed in a position against the housing; a rotating part connected to the fixed part through a rotating shaft extending in the vertical direction and rotates relative to the fixed part as a center of the rotating shaft; and a rotating shaft driving part that rotates the rotating shaft; wherein the fixed part includes a power-transmission unit that transmits electric power in noncontact state; and the rotating part includes a rotating shelf on which objects are disposed; a power drive device disposed to rotate integrally with the rotating shelf and driven by electric power; and a power-receiving unit that supplies the electric power transmitted from the power-transmission unit to the power drive device.

First claim

The invention claimed is:

1. A storage apparatus that stores objects comprising:
a housing;
a fixed part disposed in the housing and fixed in a position against the housing;
a rotating part connected to the fixed part through a rotating shaft extending in the vertical direction and rotates relative to the fixed part as a center of the rotating shaft; and
a rotating shaft driving part that rotates the rotating shaft; wherein
the fixed part comprises a power-transmission unit that transmits electric power in non-contact state; and
the rotating part comprising:
a rotating shelf on which objects are disposed;
a power drive device that integrally rotates with the rotating shelf and is driven by electric power; and
a power-receiving unit that supplies the electric power transmitted from the power-transmission unit to the power drive device.

2. The storage apparatus according to claim 1 , wherein
the power-transmission unit includes,
a support that surrounds at least a part of the outer circumferential of the rotating shaft, and
a conductor disposed on the support along a direction in which the support extends,
wherein the power-receiving unit comprises a coil formed by winding a conductive component, and
when a magnetic field is generated by flowing a current through the conductor of the power-transmission unit, an induced current is generated in the coil of the power-receiving unit.

3. The storage apparatus according to claim 2 , wherein the conductor is provided by a circuit pattern of a printed board.

4. The storage apparatus according to claim 2 , wherein
the support has a conductor guiding part formed to extend in the circumferential direction, and
the conductor is disposed along the conductor guiding part.

5. The storage apparatus according to claim 2 , wherein the power-transmission unit has a magnetic sheet provided on a side opposite a side where the conductor and the power-receiving unit face each other.

6. The storage apparatus according to claim 5 , wherein another component is disposed or a gap is formed between the conductor and the magnetic sheet.

7. The storage apparatus according to claim 6 , wherein a plate member made of a non-magnetic material is disposed between the conductor and the magnetic sheet.

8. The storage apparatus according to claim 1 , further comprising:
at least two power-receiving units disposed on a circumference around the rotating shaft, wherein
the power-transmission unit is disposed to face a rotation track of the power-receiving unit, and
when viewed in a direction parallel to the rotating shaft, the power-transmission unit is formed in a circle arc shape having an opening along a circumferential direction of the rotating shaft and disposed to always overlap at least one of the power-receiving unit.

9. The storage apparatus according to claim 8 , wherein
the opening is formed in a size through which the rotating shaft can pass through, and
the power-transmission unit is detachably mounted to an outer circumferential side of the rotating shaft.

10. The storage apparatus according to claim 1 , wherein the power drive device includes at least one of a temperature sensor, a humidity sensor, a gas component detector and a camera.
