Abstract
A conveyor device is described in which a conveyor roller is used to convey a medium inside a printing device with the conveyor roller extending in a width direction of the printing device. The conveyor roller receives a force from a following roller configured to face the conveyor roller. The conveyor roller is supported by one or more bearings. The one or more bearings include a shaft supporting portion that extends in the width direction to support the conveyor roller against the force of the following roller.
Claims16
A conveyor device comprising:
- a conveyor roller extending in a width direction orthogonal to a conveyance direction;
- a following roller disposed facing the conveyor roller;
- a first urging member configured to urge the following roller toward the conveyor roller;
- and
- a bearing configured to rotatably support the conveyor roller, and the bearing including:
- a first shaft-support portion configured to rotatably support the conveyor roller and disposed outside of a conveyance area of the conveyor roller in the width direction;
- and
- a second shaft-support portion extending from the first shaft-support portion to the conveyance area with respect to the width direction, and configured to rotatably support the conveyor roller and expose a portion of a circumference of the conveyor roller with the exposed portion being on a same side as a side of the conveyor roller facing the following roller.
A conveyor device comprising:
- a conveyor roller extending in a width direction orthogonal to a conveyance direction, the conveyor roller configured to receive a force orthogonal to both the width direction and the conveyance direction;
- a bearing configured to rotatably support the conveyor roller, and the bearing including:
- a first shaft-support portion configured to rotatably support the conveyor roller and disposed outside of a conveyance area of the conveyor roller in the width direction;
- and
- a second shaft-support portion extending from the first shaft-support portion at least to the conveyance area with respect to the width direction, and configured to rotatably support the conveyor roller and expose a portion of a surface of the conveyor roller to the conveyance area.
A conveyor device comprising:
- a conveyor roller extending in a width direction orthogonal to a conveyance direction, the conveyor roller configured to receive a force in a direction orthogonal to both the width direction and the conveyance direction, the conveyor roller include a circumference;
- a platen located downstream from the conveyor roller in the conveyance direction, the platen having a side extending in the conveyance direction;
- a bearing configured to rotatably support the conveyor roller, and the bearing including:
- a first shaft-support portion configured to rotatably support the conveyor roller;
- and
- a second shaft-support portion extending from the first shaft-support portion in the width direction such that the second portion extends in the width direction past the side of the platen, the second shaft-support portion encircling less than all of the circumference of the conveyor roller, and the second shaft-support portion being configured to rotatably support the conveyor roller opposite to the force direction.
