Abstract
A printing apparatus includes a conveyance path including a curving part, an inversion path for inverting a medium upside down, and a control unit, and the control unit includes a first mode for conveying the long medium at a first speed when a surface that faces inside when the long medium is rolled in a roll shape and a surface that faces inside when conveyed in a curved shape through the curving part are the same, and a second mode for conveying the long medium at a second speed lower than the first speed of the first mode when the surface that faces inside when the long medium is rolled in the roll shape and the surface that faces inside when conveyed in the curved shape through the curving part are different from each other.
Claims14
A printing apparatus comprising:
- a curving part configured to convey a medium in a curved state;
- a printing unit configured to perform printing on the medium;
- a cutting unit configured to cut the medium on which printing was performed;
- an ejection part configured to eject the cut medium;
- a conveyance path including a conveyance unit configured to convey the medium through the curving part, the printing unit, the cutting unit, and the ejection part in this order;
- an inversion path configured to invert a single sheet medium upside down and merge the single sheet medium into an upstream part of the curving part of the conveyance path for printing on a second surface, the single sheet medium being formed by cutting a long medium on which printing was performed on a first surface, the medium being initially the long medium having a roll shape;
- and
- a control unit configured to control the conveyance unit,
- wherein in conveyance of the long medium or the single sheet medium at the curving part, the control unit controls the conveyance unit in a first mode and a second mode to convey the long medium or the single sheet medium toward the printing unit, the control unit controlling the conveyance unit in the first mode and the second mode based, at least in part, upon an orientation of the long medium sent out from a roll sheet associated with the printing apparatus,
- the first mode being a mode for conveying the long medium or the single sheet medium at a first speed when a surface of the long medium or the single sheet medium being conveyed that faces inside when the long medium or the single sheet medium is rolled in a roll shape, and a surface of the long medium or the single sheet medium that faces inside of a curved shape when the long medium or the single sheet medium is conveyed through the curving part are the same, and
- the second mode being a mode for conveying the long medium or the single sheet medium at a second speed lower than the first speed of the first mode when the surface of the long medium or the single sheet medium being conveyed that faces inside when the long medium or the single sheet medium is rolled in the roll shape, and the surface of the long medium or the single sheet medium that faces inside of the curved shape when the long medium or the single sheet medium is conveyed through the curving part are different from each other.

A conveyance control method of a medium using a printing apparatus configured to perform printing on the medium, the medium being initially a long medium having a roll shape,
- the printing apparatus comprising:
- a curving part configured to convey a medium in a curved state;
- a printing unit configured to perform printing on the medium;
- a cutting unit configured to cut the medium on which printing was performed;
- an ejection part configured to eject a cut medium;
- a conveyance path including a conveyance unit configured to convey the medium through the curving part, the printing unit, the cutting unit, and the ejection part in this order;
- and
- an inversion path configured to invert a single sheet medium upside down and merge the single sheet medium into an upstream part of the curving part of the conveyance path for printing on a second surface, the single sheet medium being formed by cutting the long medium on which printing was performed on a first surface,
- the method comprising, in conveyance of the long medium or the single sheet medium at the curving part:
- a first mode step for conveying the long medium or the single sheet medium at a first speed when a surface of the long medium or the single sheet medium being conveyed that faces inside when the long medium or the single sheet medium is rolled in a roll shape, and a surface of the long medium or the single sheet medium that faces inside of a curved shape when the long medium or the single sheet medium is conveyed through the curving part are the same, and
- a second mode step for conveying the long medium or the single sheet medium at a second speed lower than the first speed of the first mode step when the surface of the long medium or the single sheet medium being conveyed that faces inside when the long medium or the single sheet medium is rolled in the roll shape, and the surface of the long medium or the single sheet medium that faces inside of the curved shape when the long medium or the single sheet medium is conveyed through the curving part are different from each other,
- controlling between the first mode step and the second mode step is based, at least in part, upon an orientation of the long medium sent out from a roll sheet associated with the printing apparatus.
