Patent ID: 8459886

Claim:
A printing device comprising: a control unit; a first printing unit, controlled by the control unit, to perform printing at a predetermined first printing position on a convey path for an elongated printing medium by a first printing step on the printing medium; a cutting unit, controlled by the control unit, to cut apart a portion of the printing medium on which the printing has been performed by the first printing unit, as a printing medium strip by cutting the printing medium at a predetermined cutting position, on the convey path, located in a first direction to convey the printing medium with respect to the first printing position; a second printing unit, controlled by the control unit, to perform an overcoat printing process by a second printing step on the printing medium strip cut apart by the cutting unit, at a predetermined second printing position, on the convey path, located in the first direction with respect to the cutting position, the second printing step being performed in parallel with a next printing by the first printing unit, on the printing medium from which the printing medium strip has been cut apart; a first rotation unit controlled by the control unit, to nip the printing medium, and to convey the printing medium by rotating, at a predetermined first nip position, on the convey path, located in a second direction opposite to the first direction with respect to the first printing position, the first rotation unit serving to convey the printing medium before the printing by the first printing unit, in the first direction until a printing start point on the printing medium coincides with the first printing position, serving to convey the printing medium in the second direction after the first printing unit starts the printing until a printing end point on the printing medium comes to the first printing position, and serving to convey the printing medium in the first direction after the first printing unit ends the printing on the printing medium; and a second rotation unit controlled by the control unit, to nip a portion of the printing medium which is to become the printing medium strip upon being cut by the cutting unit, at a second nip position, on the convey path, located at one of the same position as the second printing position and a position located in the first direction with respect to the second printing position, and to convey, by rotating, the printing medium and the printing medium strip cut apart from the printing medium by the cutting unit, the second rotation unit serving to nip the printing medium on which the first printing unit performs printing and which is conveyed by the first rotation unit, and serving to convey the printing medium strip cut apart by the cutting unit, in the first direction after the second printing unit starts printing.
