Abstract
A printing device has a guide roller that guides a print medium in a conveyance direction; an intersect roller pair that holds the print medium guided by the guide roller between a first roller that rotates on an axis of rotation in the conveyance direction of the print medium and a second roller that rotates on an axis of rotation that intersects the axis of rotation of the first roller; a conveyance roller pair that conveys the print medium held by the intersect roller pair in the conveyance direction by a conveyance drive roller driven by a drive means and a conveyance follower roller that rotates with the conveyance drive roller; and a print unit that prints on the print medium conveyed by the conveyance roller pair.
Claims16
A printing device, comprising:
- a guide roller configured to guide a print medium in a conveyance direction;
- an intersect roller pair configured to hold the print medium guided by the guide roller between a first roller rotatable on an axis of rotation in the conveyance direction of the print medium and a second roller rotatable on an axis of rotation perpendicular to the axis of rotation of the first roller;
- a conveyance roller pair configured to convey the print medium held by the intersect roller pair in the conveyance direction by a conveyance drive roller driven by a drive mechanism and a conveyance follower roller rotatable with the conveyance drive roller;
- and
- a print unit configured to print on the print medium conveyed by the conveyance roller pair,
- wherein the first roller and the second roller are disposed above one another such that the centers of each roller are disposed along the same axis, said axis being normal to the axis of rotation,
- wherein the printing device further comprises a guide configured to guide one edge of the print medium in the conveyance direction,
- wherein the conveyance roller pair is disposed substantially in a center of the print medium width perpendicular to the conveyance direction, and
- wherein the intersect roller pair is disposed on a side of the opposite edge of the print medium as the one edge in the conveyance direction.
A conveyance device for a printing device, the conveyance device comprising:
- an intersect roller pair configured to hold a conveyed print medium between a first roller that rotates on an axis of rotation in the conveyance direction of the print medium and a second roller configured to rotate on an axis of rotation perpendicular to the axis of rotation of the first roller;
- and
- a conveyance roller pair configured to convey the print medium held by the intersect roller pair in the conveyance direction by a conveyance drive roller driven by a drive mechanism and a conveyance follower roller configured to rotate with the conveyance drive roller,
- wherein the first roller and the second roller are disposed above one another such that the centers of each roller are disposed along the same axis, said axis being normal to the axis of rotation,
- wherein the conveyance device for a printing device further comprises a guide configured to guide one edge of the print medium in the conveyance direction,
- wherein the side stops are arranged in series along one side of the conveyance direction of the conveyed print medium,
- wherein the urging unit is configured to apply a force to the conveyed print medium in a direction toward the side stops, and
- wherein the force applied by the urging unit is such that the conveyed print medium contacts at least two consecutive side stops substantially evenly.
A printing device, comprising:
- a guide roller configured to guide a print medium in a conveyance direction;
- an intersect roller pair configured to hold the print medium guided by the guide roller between a first roller rotatable on an axis of rotation in the conveyance direction of the print medium and a second roller rotatable on an axis of rotation perpendicular to the axis of rotation of the first roller;
- a conveyance roller pair configured to convey the print medium held by the intersect roller pair in the conveyance direction by a conveyance drive roller driven by a drive mechanism and a conveyance follower roller rotatable with the conveyance drive roller;
- a print unit configured to print on the print medium conveyed by the conveyance roller pair;
- and
- at least two urging units and at least two side stops, wherein respective urging units are located directly across from respective side stops in a direction normal to the conveyance direction.
