Description

Image printing apparatus and method of driving the same

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printing machine and a printing method thereof, and more particularly, to a printing machine and a printing method thereof capable of adjusting a direction in which a printing surface of a paper on which an image is printed is placed on a delivery box.

In general, most single-sided printing machines which print an image on one side of the paper are configured such that the printing surface of the paper on which the image is printed through the printing process can be discharged to face the bottom surface of the delivery tray. Therefore, when the print data of one file is processed by such a printing paper discharge method, since printed matters are sequentially loaded in the page order from the bottom surface of the delivery bin, no separate document cleaning operation is required. That is, if the user only flips the entire printed matter loaded in the delivery box, the printed matter accumulated in the order of pages can be obtained.

However, when a print job corresponding to a plurality of files is continuously performed and printed matters of different files are sequentially loaded in a discharge box, there is a disadvantage in that the printed matters which are apparently loaded cannot be distinguished for each file. Therefore, when several printed matters are stacked together in the delivery box, in order to separate their printed matters, it is inconvenient to check the contents of the loaded printed matter one by one.

The present invention was devised to improve the above-described problems, and a printing machine and a printing method for facilitating classification of printed matters by allowing printed matters to be sequentially output through the printing process to be loaded into the discharge bin so as to be distinguished easily by file. The purpose is to provide.

In the step (c), it is preferable that the entire pages of the received file to be printed are sequentially printed on paper and discharged from the image corresponding to the last page to the image of the first page in the reverse order of the pages.

Hereinafter, a printer and a printing method thereof according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a printing press according to the present invention.

Referring to the drawings, the printer 20 and the computer 10 are interconnected by the communication interface 30. The computer 10 includes a central processing unit (CPU) 11, a display device 12, an input device 13, and a storage device 14 interconnected by a bus 15.

The printer driver 14a installed in the storage device 14 provides a print specification selection menu through a screen of the display device 12 so as to select a print specification for a print target file specified by the user, and prints selected by the user. The specification information is transmitted to the printer 20 together with the file data to be printed. Preferably, the print specification selection menu 14b provided through the screen of the display device 12 by the printer driver 14a prints an image of one page only on one side of the paper as shown in FIG. It provides a selection menu for selecting one of face up mode and face down mode for single-sided printing.

The printer driver 14a transmits the selected print specification information to the printer 20 through the communication interface 30 together with the print target file.

The printer 20 includes an input device 23, a main controller 21, an engine controller 26, a display device 22, a print engine 40, and a storage device 24.

The input device 23 installed outside the main body of the printer 20 is provided with function selection input keys. Preferably, the input device 23 is provided with a face up / down output mode selection key.

The controller consists of a main controller 21 and an engine controller 26.

The main controller 21 processes the signal input from the input device 23 and processes the information received from the computer 10 through the communication interface 30. The main controller 21 controls the engine controller 26 so that a print job corresponding to a print specification set for the received print data file can be performed.

The engine controller 26 controls the print engine 40.

Referring to FIG. 3, the printing engine 40 has a printing unit 41, a paper supply unit 48, and a reverse transfer unit 46.

The printing unit 41 includes a photosensitive drum 42, a light scanning device 43, a developing device 44, and a transfer device 45. A photosensitive belt may be used instead of the photosensitive drum 42 as a photosensitive medium. The paper feed unit 48 includes a tray 49 on which the paper 51 is loaded, and a plurality of feed rollers 52 installed on the paper feed path 50 from the tray 49 to the transfer device 45. .

The reverse feeder 46 is branched at a predetermined position on the discharge path 53 from the transfer device 45 to the discharge bin 55 and reversed to the paper input end 45a of the transfer device 45. ) The up and down is controlled by the engine controller 26 of the interference member 56 rotatably provided on the discharge path 53. When the interference member 56 is in the up position, the paper 51 via the transfer device 45 interferes with the paper to enter the reverse feed path 47. When the interference member 56 is in the down position, the transfer device 45 is moved. It does not interfere with the passing paper 51. That is, when the interference member 56 is set to the down position, the paper 51 which has passed through the transfer device 45 is discharged to the discharge bin 55 along the discharge path 53 as it is.

The reverse conveyance unit 46 is configured such that the upper and lower surfaces of the paper 51 are turned upside down while the paper 51 travels along the reverse conveyance path 47. That is, the traveling leading end portion and the trailing edge portion of the paper 51 may be reversed in the process of passing the paper drop portion 46a provided in the middle of the reverse feed path 47. The paper 51 which has passed through the paper drop section 46a is conveyed to the input terminal 45a of the transfer device 45 again.

Meanwhile, as described above, the face up / down output mode may be set through the input device 23 of the computer 10 and / or the printer 20.

That is, without providing the face up / down output mode selection key 23a on the input device 23 of the printer 20, the face up / down output mode selection information from the computer 10 is printed together with the print data file. 20). In this case, the main controller 21 controls the engine controller 26 to perform a print job corresponding to the output mode read from the print specification information.

Alternatively, a face up / down output mode selection key 23a is provided on the input device 23 of the printer 20, and a print job for the print target file received according to the output mode selected by the input device 23 is provided. May be performed.

Alternatively, the computer 10 and the input device 23 may both set the face up / down output modes. When the output mode selection information is input from both the input device 23 and the computer 10, the main controller 21 is set to select only one input signal of the input device 23 and the computer 10. do. Preferably, the controller 21 causes the printing operation to be performed according to the output mode selection information input from the computer 10.

Hereinafter, a printing method according to the present invention will be described with reference to FIG.

First, one of the face up output mode and the face down output mode is selected using the computer 10 and / or the input device 23 (step 110). When the output mode is selected by the computer 10, output mode selection information is transmitted to the main controller 21 together with the print target file.

The main controller 21 reads output mode selection information (step 120).

If the output mode selected in step 120 is determined to be a face-down output mode, the main controller 21 causes the engine controller to print an image on the paper 51 in the order of pages from the first page of the file to be printed and to be discharged. 26) (step 130). That is, in the face down output mode, the main controller 21 outputs the face down output mode signal to the engine controller 26, and the engine controller 26 in order from the image data of the first page of the file to be printed. Output to. The engine controller 26 sets the interference member 56 in the down position and controls the printing unit 41 to form an image corresponding to the image data input in the page order on the photosensitive drum 42. The image formed on the photosensitive drum 42 is transferred to the inserted paper 51 via the transfer roller 45b. The paper 51 whose image is printed on the lower surface via the transfer device 45 is discharged to the discharge bin 55 along the discharge path 53 (step 140). As a result, the image printing surface of the paper 51 to be stacked on the delivery tray 55 is placed to face the bottom surface of the delivery container 55. Therefore, when looking down the paper 51 loaded on the upper surface of the delivery box 55, the printing surface is not visible as shown in FIG. 5A.

On the other hand, if the output mode selected in step 120 is determined to be the face-up output mode, the main controller 21 is the engine controller so that the image is printed on the paper 51 from the last page of the file to be printed in reverse order (26) Control (step 150). That is, the main controller 21 outputs the face up output mode signal to the engine controller 26, and outputs the face up output mode signal to the engine controller 26 in reverse order from the image data of the last page of the file to be printed. The engine controller 26 sets the interference member 56 in the up position, controls the printing unit 41 to display the image corresponding to the image data of one page amount input in the page order to the photosensitive drum 42. To form. The image formed on the photosensitive drum 42 is transferred to the inserted paper 51 via the transfer roller 45b. The paper 51 whose image is printed on the lower surface via the transfer device 45 is interfered with the interference member 56 and travels along the reverse feed path 47. The interference member 56 is moved back to the down position. The paper 51 traveling along the reverse feed path 47 is turned upside down and retracted into the transfer device 45. The paper 51 which has passed through the reverse feed path 47 is controlled so that image transfer is not performed again. The paper 51 which has passed through the transfer device 45 is discharged into the discharge bin 55 along the discharge path 53. This process is carried out until the image corresponding to the first page is printed on the paper 51 and discharged continuously in reverse page order. As a result, in the face-up output mode, the sheets 51 are sequentially loaded in the discharge tray 55 in the reverse order of the pages. And the upper surface of the sheet | seat 51 to be loaded becomes an image printing surface. Therefore, when looking down the paper 51 loaded on the upper surface of the delivery box 55, the printing surface is shown as shown in FIG. 5B.

Therefore, when the plurality of print target files are to be transmitted to the printer 20, when the face up output mode and the face down output mode are alternately set for each file according to the transmission order to the printer 20, the discharge of the printer 20 is performed. In the box 55, the directions in which the printing surface of the paper 51 is placed for each file are stacked differently. Therefore, it facilitates the file-by-file classification of the printed matter loaded in the stacking box 55.

According to the printing machine and the printing method according to the present invention as described so far, it is possible to select the direction in which the printing surface of the printed matter to be placed on the delivery box to facilitate the classification of the printed files by file.
