Abstract
There is provided a printer including: an ink-jet head; a first rotatable body; a first attaching mechanism attaching a printing medium to the first rotatable body; a separating mechanism separating the printing medium from the first rotatable body; and a control mechanism. In the printer, first to forth routes are formed. In transporting the printing medium, the control mechanism causes the printing medium having been subjected to printing on a first surface by the ink-jet head to pass through the first route, next to pass through the second route and the third route at least once, thereafter to separate from the first rotatable body, and further to pass through the fourth route to be reversed.
Claims17
A printer which performs printing by jetting an ink onto a printing medium, the printer comprising:
- an ink-jet head jetting the ink onto the printing medium;
- a first rotatable body which has an outer peripheral surface;
- a first attaching mechanism attaching the printing medium to the outer peripheral surface of the first rotatable body;
- a separating mechanism separating the printing medium attached to the outer peripheral surface of the first rotatable body from the first rotatable body;
- a first rotational drive mechanism driving the first rotatable body;
- and
- a control mechanism controlling the first attaching mechanism, the separating mechanism, and the first rotational drive mechanism,
- wherein a transporting route is formed in the printer through which the printing medium is transported, the transporting route including:
- a first route extending from a facing position facing the ink-jet head to a first position which is located on the outer peripheral surface and to which the printing medium having been subjected to the printing on a first surface is transferred;
- a second route formed on the outer peripheral surface and extending from the first position to a second position at which the printing medium is separated from the first rotatable body by the separating mechanism;
- a third route formed on the outer peripheral surface and extending from the second position to the first position;
- and a fourth route extending from the second position to the facing position;
- and
- when the printing medium is transported, the control mechanism controls the first attaching mechanism, the separating mechanism, and the first rotational drive mechanism such that the printing medium is transported through the first route in a state that the printed first surface is exposed, then the printing medium is transported through the second route and the third route at least once while being attached to the outer peripheral surface of the first rotatable body, then the printing medium is separated from the first rotatable body by the separating mechanism, and further the printing medium is transported through the fourth route to be transported toward the ink-jet head while a second surface opposite the first surface is exposed.

A printer which performs a printing by jetting an ink onto an printing medium, the printer comprising:
- an ink-jet head jetting the ink onto the printing medium;
- a rotatable body which is rotatable;
- a attaching mechanism attaching the printing medium to an outer peripheral surface of the rotatable body;
- a rotational drive mechanism driving the rotatable body;
- a separating mechanism separating the printing medium attached to the outer peripheral surface of the rotatable body from the first rotatable body;
- and
- a control mechanism controlling the attaching mechanism, the separating mechanism, and the rotary-driving mechanism,
- wherein a transporting route is formed in the printer through which the printing medium is transported, the transporting route including:
- a first route extending from a facing position facing the ink-jet head to a first position which is located on the outer peripheral surface and to which the printing medium having been subjected to the printing on a first surface is transferred;
- a second transporting route formed on the outer peripheral surface and extending from the first position to a second position at which the printing medium is separated from the first rotatable body by the separating mechanism;
- and a third transporting route extending from the second position to the facing position;
- when the printing paper is transported, the control mechanism controls the attaching mechanism, the separating mechanism, and the rotary-driving mechanism such that the printing medium is transported through the first route in a state that the printed first surface is exposed, then the printing medium is separated from the rotatable body by the separating mechanism after the printing medium is kept attached on the outer peripheral surface for a predetermined time, and then the printing medium is transported through the third transporting route to be transported toward the ink-jet head while a second surface opposite the first surface is exposed;
- and
- the control mechanism further determines the predetermined time based on a printing duty of the first surface of the printing medium or an environmental condition in the printer.
