Abstract
A lifting apparatus includes a motor, circular support members, power transmission members, guide mechanisms, and electromagnets. The circular support members provide tensile forces to wires connected to a load. The power transmission members rotate around the rotation axis Ax as a center of rotation by driving force of the motor. The guide mechanisms support the circular support members so as to enable the circular support members to slide in a predetermined ranges along a radial direction of the rotation axis, respectively. The electromagnets forcibly arrange the circular support members using electromagnetic force at a position that the center axes of the circular support members agree with the rotation axis in the predetermined ranges.
Claims7
A lifting apparatus that causes a load to move up and down, comprising:
- a motor;
- a first circular support member configured to provide tensile force to a first wire connected to the load;
- a first power transmission member configured to rotate around a rotation axis as a center of rotation by driving force of the motor;
- a first guide mechanism configured to support the first circular support member so as to enable the first circular support member to slide in a predetermined first range along a radial direction of the rotation axis;
- a first electromagnet configured to forcibly arrange the first circular support member using electromagnetic force at a position that a center axis of the first circular support member agrees with the rotation axis in the predetermined first range;
- a second circular support member configured to provide tensile force to a second wire connected to the load;
- a second power transmission member configured to rotate around the rotation axis as a center of rotation by driving force of the motor;
- a second guide mechanism configured to support the second circular support member so as to enable the second circular support member to slide in a predetermined second range along a radial direction of the rotation axis;
- and
- a second electromagnet configured to forcibly arrange the second circular support member using electromagnetic force at a position that a center axis of the second circular support member agrees with the rotation axis in the predetermined second range.
A sheet storage apparatus, comprising:
- a lifting apparatus;
- and
- a sheet loading unit configured to be caused to move up and down by the lifting apparatus;
- wherein the lifting apparatus comprises:
- a motor;
- a first circular support member configured to provide tensile force to a first wire connected to the sheet loading unit;
- a first power transmission member configured to rotate around a rotation axis as a center of rotation by driving force of the motor;
- a first guide mechanism configured to support the first circular support member so as to enable the first circular support member to slide in a predetermined first range along a radial direction of the rotation axis;
- a first electromagnet configured to forcibly arrange the first circular support member using electromagnetic force at a position that a center axis of the first circular support member agrees with the rotation axis in the predetermined first range;
- a second circular support member configured to provide tensile force to a second wire connected to the sheet loading unit;
- a second power transmission member configured to rotate around the rotation axis as a center of rotation by driving force of the motor;
- a second guide mechanism configured to support the second circular support member so as to enable the second circular support member to slide in a predetermined second range along a radial direction of the rotation axis;
- and
- a second electromagnet configured to forcibly arrange the second circular support member using electromagnetic force at a position that a center axis of the second circular support member agrees with the rotation axis in the predetermined second range.
