Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double-sided or single-sided optional digital printing apparatus,

Generally, it is a very common technology to print on both sides or in cross-sections in office compact printers that mainly use A4 paper. However, the present invention relates to a digital printing apparatus capable of printing on both sides or in cross-sections in a digital printer which is output in a large size continuously, rather than only in a duplex printing.

As a precedent document related to duplex printing in a small office printer which mainly uses A4 paper, Korean Patent Registration No. 10-0629489. (Hereinafter referred to as "Patent Document 1") proposed a two-sided printing method in an office compact printer.

[0005] [Patent Document 1] discloses a method in which a first side of an A4 sheet passes through a printing unit and then comes out of the output unit for a while, and then turns over to a second side of A4, And the two-sided printing can be performed through passing through the part again. In the above-described Patent Document 1, duplex printing is possible only on paper cut to a certain size such as A4 paper, and the speed of duplex printing is relatively slow. Therefore, it is suitable for office compact printers that perform relatively little printing.

In relation to double-sided printing, U.S. Patent Publication No. 5284816, Publication Date 1994.02.08 (hereinafter referred to as "Patent Document 2") proposes a two-sided printing having two printing portions, a first printing portion and a second printing portion.

In the above-described Patent Document 2, the first printing unit in which the print head is disposed in the upper direction in the method proposed by Kodak prints the first side of the paper to be printed, and the lower side And the second printing unit in which the print head is disposed prints the second surface of the paper to be printed.

The double-sided printing method proposed in the above Patent Document 2 is advantageous in that duplex printing can be performed not only on paper cut to a certain size such as A4 paper but also on continuous paper, However, there is a problem that the second printing unit is not suitable because the print head is disposed in the lower direction in the large-size printing.

(Hereinafter referred to as " Patent Document 3 ") in relation to double-sided printing in a digital printer which prints a large-size continuous image, according to US-A-7390133.

The above-described [Patent Document 3] is a method in which a double-sided printing is possible in a digital printer which is outputted continuously in a large size by a scheme proposed by Screen Co., This prints the first side of a print sheet which is continuously output in a large size and changes the direction of movement of the print sheet by reversing the direction of the paper twice by 90 degrees and then reversing the paper 180 degrees to form a large size And printing the second side of the continuous printing paper.

Patent Document 3 has a disadvantage in that double-sided printing and double-sided printing can not be selected. However, precise control of the printing paper is required in order to change the moving direction of the printing paper by reversing the movement of the printing paper two times by 90 degrees. .

[Patent Document 1] Korean Patent Publication No. 10-0629489. Date of Notification 2006. 09. 28. [Patent Document 2] U.S. Patent No. 5284816, Published on Mar. 02, 1994 [Patent Document 3] U.S. Patent No. 7390133, Published on June 26, 2008

In the present invention, a digital printing apparatus capable of printing on both sides or in cross-sections in addition to double-side printing in a digital printer outputting continuous large-size (continuous) is proposed. In a conventional digital printer which is continuously outputting large-size images, only double-side printing was possible through the method of [Patent Document 3] proposed by Screen Corporation. Patent Document 3 discloses that there is a first printing unit and a second printing unit that respectively print first and second surfaces of a large and continuous print paper, The printing paper must pass through the first and second printing units. In Patent Document 3, there is a problem that only two-sided printing can be performed, and printing can not be performed by selecting both sides or sections. The present invention proposes a digital printer capable of outputting a continuous large-sized continuous print which is improved in the manner of the above-described [Patent Document 3] and can be selectively printed on both sides or cross sections.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital printing apparatus capable of selectively printing on both sides or in sections, not only in a duplex printing, in a digital printer outputting a large size continuously. And has a general printing unit 40 and a switching printing unit 41 for selecting both sides and simplex printing. The first surface of the paper 100 to be printed is printed by the general printing unit 40 and the second surface is printed by the switching printing unit 41. [ In particular, the transfer printing section 41 is provided with a transfer printing head section 43-1 for printing a second side of the paper 100 to be printed, And a double-sided or single-sided switching device 55 capable of determining whether or not a single-sided or single-sided switching device 55 can be installed.

As a solution to the problem, a digital printing apparatus capable of selecting a double-sided printing or a single-sided printing on a digital printer, rather than a double-sided printing.

However, in the present invention, in a digital printer outputting a continuous large-size image, a digital printer capable of printing on both sides or one side in a cross-section, Device. Thus, there is an increased effect that it is possible to easily switch between single-sided printing or double-sided printing in a digital printer which is continuously output in a large size.
