Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a printing apparatus, and more particularly, to a printing apparatus that prints an image on a continuous sheet with no margins and performs automatic cutting.
[0002]
[Prior art]
In recent years, technology development for realizing printing with no margins on a printer has been promoted and commercialized. In marginless printing, as shown in FIG. 9, the image to be printed is enlarged to generate an image 702 having a size slightly larger than the paper size 701. By printing this enlarged image, no margins are generated on the four sides. I am doing so.
[0003]
Printing without margins is mainly performed on regular cut sheets such as A4 and B5, but marginless printing targeting continuous paper such as roll paper is also in practical use.
[0004]
On the other hand, some printers that print on continuous paper such as rolls include a cutter for automatically cutting paper in a specified size after printing.
[0005]
FIG. 10 is a schematic side sectional view of a printer 710 for explaining a printing mechanism, a paper feeding mechanism, and a cutting mechanism of a printer provided with a cutter in a housing. Here, a case where roll paper 722 is used as print paper will be described as an example.
[0006]
A conventional printer 710 with a cutting function includes an apparatus main body 723 and a roll paper cassette 724 in which roll paper 722 is set.
[0007]
The roll paper 722 is attached to the drum-shaped paper tube 727 while being pushed through the shaft portion 728, and the paper tube 727 is placed on a pair of front and rear rollers 729 and 730 disposed at the bottom of the roll paper cassette 724. Is accommodated in a state where the collar portion 731 is placed. A roll paper motor 732 for driving the drive roller 730 is disposed on the bottom rear side of the roll paper cassette 724. When the roll paper motor 32 is driven to rotate forward, a rotational force is transmitted from the drive roller 730 to the collar portion 731, and the roll paper 722 rotates in the direction of feeding the paper. On the other hand, when the roll paper motor 732 is driven in reverse, a rotational force is transmitted from the drive roller 730 to the collar portion 731 and the roll paper 722 rotates in the direction of winding the paper.
[0008]
A paper feeding device 733 is disposed at the front end of the roll paper cassette 724 at a position corresponding to the transport path of the roll paper 722 sent from the roll paper 722. The sheet feeding device 733 includes a sheet feeding driven roller 735 and a sheet feeding driving roller 736, and sends the roll paper 722 to the apparatus main body 723 side. In the apparatus main body 723, a conveyance roller 737 and a paper discharge roller 738 are arranged from the upstream side.
[0009]
The apparatus main body 723 includes a carriage shaft 740, and a carriage 741 is slidably supported on the carriage shaft 740. A recording head 743 is attached to the lower surface of the carriage 741, and ink droplets are ejected from nozzle holes (not shown) of the recording head 743 to print on the roll paper 722. The recording head 743 is connected to an ink cartridge (not shown) separate from the apparatus main body 723 and receives ink supplied from the ink cartridge. A platen 39 is disposed between the transport roller 737 and the paper discharge roller 738 in the paper feed direction.
[0010]
The apparatus main body 723 is provided with a cutter device 745 for cutting the printed roll paper 722. The cutter device 745 is positioned as an option in consideration of the spread of roll paper printing. For this reason, it arrange | positions near the exterior of a housing | casing so that a user may mount | wear easily later. Accordingly, cutting is performed on the paper discharge side from the recording head 743.
[0011]
The cutter device 745 includes a cutter 746 as processing means. The cutter 746 is arranged in the width direction of the roll paper 722 (a direction orthogonal to the paper feed direction) in a state where the movable blade 746a is severably engaged with the fixed blade 746b. The roll paper 722 is cut by moving. The roll paper 722 cut by the cutter 746 is discharged to the outside of the apparatus main body 23 by the auxiliary drive roller 748 of the cutter apparatus 745.
[0012]
When printing without margins on continuous paper such as roll paper with such a printer 710 having a cutting function, for example, as shown in FIG. A method of cutting at the boundary line has been put into practical use (one-time cutting method).
[0013]
However, since the cutting is performed mechanically and there is an error in the cutting position, in the one-time cutting method in which the images are continuous without margins, there is a possibility that the previous and subsequent images may enter the image after the cutting. is there. For example, when the previous image is an image based on black and the back image is an image based on a light color, the previous image enters the cut position of the back image and the black line becomes conspicuous Etc.
[0014]
When such front and back images enter, the quality of the print result is deteriorated. For this reason, in a printer that performs printing with no margins on continuous paper such as roll paper, as shown in FIG. 11B, a gap is provided between images before and after the enlargement, and printing is performed. By cutting a little inside the image, it is possible to prevent the front and back images from entering.
[0015]
[Problems to be solved by the invention]
However, according to a method (two-cut method) in which a gap is provided between images before and after enlargement and printing is performed and the inside of the image is cut slightly (a two-time cut method), it is necessary to cut twice between images. When cutting, in order to stop paper feeding once, in this method, it is necessary to interrupt printing twice.
[0016]
For this reason, the two-time cut method that prevents the front and rear images from entering takes longer time than the one-time cut method that allows the image to enter.
[0017]
Further, when the front and back images are cut twice, chips are generated between the images.
[0018]
An object of the present invention is to shorten the printing time in a printing apparatus that prevents the front and back images from entering in marginless printing on continuous paper.
[0019]
Another object of the present invention is to prevent generation of chips in a printing apparatus that prevents the front and back images from entering in marginless printing on continuous paper.

Here, a case where roll paper 22 is used as print paper will be described as an example. Of course, the printing mechanism 15, the paper feeding mechanism 16, and the cutting mechanism 17 can function in the same manner with respect to fixed-size paper and other printing media.
[0033]
FIG. 2 is a schematic side sectional view of the printer 10 for explaining the printing mechanism 15, the paper feeding mechanism 16, and the cutting mechanism 17. The printer 10 with a cutting function includes an apparatus main body 23 having a printing mechanism 15 that performs printing on roll paper 22 as printing paper, a paper feeding mechanism 16 that feeds printing paper, a cutting mechanism 17 that cuts printing paper, and the like. And a roll paper cassette 24 in which the roll paper 22 is set. Note that printing paper other than roll paper is supplied from a paper tray or a manual insertion slot (not shown).
[0034]
The roll paper 22 is attached to the drum-shaped paper tube 27 while being pushed through the shaft portion 28, and the paper tube 27 is attached to a pair of front and rear rollers 29, 30 disposed at the bottom of the roll paper cassette 24. It is accommodated in the state in which the collar part 31 was mounted. A roll paper motor 32 for driving the drive roller 30 is disposed on the bottom rear side of the roll paper cassette 24. When the roll paper motor 32 is driven to rotate forward, a rotational force is transmitted from the drive roller 30 to the collar portion 31, and the roll paper 22 rotates in the direction in which the paper is fed out. On the other hand, when the roll paper motor 32 is driven in the reverse direction, a rotational force is transmitted from the driving roller 30 to the collar portion 31, and the roll paper 22 rotates in the direction of winding the paper.
[0035]
At the front end of the roll paper cassette 24, a paper feeding device 33 is disposed at a position corresponding to the transport path of the roll paper 22 sent from the roll paper 22. The sheet feeding device 33 includes a sheet feeding driven roller 35 and a sheet feeding driving roller 36 and sends the roll paper 22 to the apparatus main body 23 side. In the apparatus main body 23, a transport roller 37 and a paper discharge roller 38 are arranged from the upstream side. These parts mainly constitute the paper feed mechanism 16.
[0036]
The apparatus main body 23 includes a carriage shaft 40, and a carriage 41 is slidably supported on the carriage shaft 40. A recording head 43 is attached to the lower surface of the carriage 41, and ink droplets are ejected from nozzle holes (not shown) of the recording head 43 to print on the roll paper 22. The recording head 43 is connected to an ink cartridge (not shown) separate from the apparatus main body 23 and receives ink supplied from the ink cartridge. A platen 39 is disposed between the transport roller 37 and the paper discharge roller 38 in the paper feed direction. These portions mainly constitute the printing mechanism 15.
[0037]
The apparatus main body 23 incorporates a cutter device 45 for cutting the roll paper 22. The cutter device 45 includes a cutter 46 as processing means, and the cutter 46 is arranged in the width direction of the roll paper 22 (a direction orthogonal to the paper feed direction) in a state where the movable blade 46a is severably engaged with the fixed blade 46b. The roll paper 22 is cut by moving. The roll paper 22 cut by the cutter 46 is sent to the printing mechanism 15 side by the auxiliary drive roller 48 of the cutter device 45. These parts mainly constitute the cutting mechanism 17.
[0038]
In the present embodiment, in view of the widespread use of roll paper printing, the cutter device 45 is standardly built in advance so that the cutter device 45 is arranged on the paper feed side from the printing mechanism 15. Therefore, the paper 22 is cut before printing by the recording head 43.
[0039]
The printing mechanism 15 is controlled by the CPU 12 executing a print command in print data sent from the computer 50. That is, the computer 50 can print an arbitrary image at an arbitrary position by transmitting print data including a drawing command to the printer 10.
[0040]
The paper feed mechanism 16 and the cutting mechanism 17 are controlled by the CPU 12 executing a roll paper feed command and a cutting command in the print data sent from the computer 50. That is, the computer 50 sends print data including a roll paper feed command and a cutting command to the printer 10 to cause the printer 10 to feed (return) an arbitrary amount of roll paper, and to cut at an arbitrary position. Can be performed.
[0041]
Next, functional configurations realized in the computer 50 and the printer 10 by the printing system will be described with reference to the block diagram of FIG.
[0042]
As shown in the figure, an application 510 and a printer driver 520 are constructed on the computer 50.
[0043]
The application 510 has a function for causing the computer 50 to perform processing such as word processing and graphics, and is constructed on the computer 50 by the CPU 51 executing an application program read by the RAM 52.
[0044]
The printer driver 520 has a function of reading image data generated by the application 510 based on an instruction from the user, converting the image data into print data that can be interpreted by the printer 10, and transmitting the print data to the printer 10 via the interface 54. is doing.
[0045]
For this reason, the printer driver 520 performs rasterizer processing for expanding the image data generated by the application 510 into image data that is an aggregate of dots, halftone processing for performing color conversion processing and halftone processing for image data, and the above processing. A print data generation unit 522 that performs a command conversion process for converting subsequent image data into a print command for controlling the printer 10 and a user interface unit 521 that receives a print condition setting, a print command, and the like from the user.
[0046]
The printer driver 520 is constructed on the computer 50 by the CPU 51 executing the printer driver program read by the RAM 52. The printer driver program for this purpose can be distributed by recording it on a portable recording medium such as a CD-ROM. The printer driver program can be installed in the computer 50 by reading this recording medium with the media reader 63. For example, it can also be installed via a computer network such as the Internet.
[0047]
In FIG. 3, a print control unit 110 and a print execution unit 120 are constructed on the printer 10.
[0048]
The print control unit 110 is realized by the CPU 12 and interprets print data transmitted from the computer 50 and performs control for executing printing based on the print data by the printer 10.
[0049]
The printing execution unit 120 is realized by the printing mechanism 15, the paper feeding mechanism 16, and the cutting mechanism 17, and executes printing on the printing paper in accordance with an instruction from the printing control unit 110.
[0050]
Next, the cutting process at the time of printing without margins on the continuous paper in the printing system will be described. In the present embodiment, the paper is cut between the paper feeding device 33 and the recording head 43. At this time, a method in which the paper is cut to a finished size in advance and then printing by the recording head 43 is started (first cutting method), and after the printing by the recording head 43 is started (during printing), the finish is completed. It is possible to selectively perform a method of cutting to a size and continuing printing (second cutting method).
[0051]
FIG. 4 is a diagram for explaining the relationship between the distance W between the cutter 46 and the recording head 43 in this process, the sheet vertical width S after cutting, and the cutting method. Among these, the distance W is fixed, but the paper vertical width S is variable according to the finished paper size.
[0052]
FIG. 4A shows a case where W is shorter than S. In this case, both the first cutting method and the second cutting method can be performed. That is, when the first cutting method is adopted, first, the paper 22 is fed until the leading edge of the paper 22 reaches a distance S from the position of the cutter 46, and cutting is performed so as to obtain a finished size. Printing is started after the paper 22 is returned until the top of the paper 22 reaches the position of the recording head 43. On the other hand, when the second cutting method is adopted, the top of the paper 22 starts printing from the position of the recording head 43 and feeds the paper 22, and the position of S from the top of the paper 22 is at the position of the cutter 46. When it comes, cut it, cut the paper, and continue printing.
[0053]
FIG. 4B shows a case where W is longer than S. In this case, the first cut method is adopted. That is, first, the paper 22 is fed until the top of the paper 22 reaches a distance S from the position of the cutter 46, and cutting is performed so as to obtain a finished size. Printing is started after the paper 22 is fed until the top of the paper 22 reaches the position of the recording head 43.
[0054]
In the design of the printer 10 with a cutting function, if the distance W is made sufficiently short, the pattern shown in FIG. 4A is obtained in most cases, so the first cut method and the second cut Any of the methods can be employed.
[0055]
The printer driver 520 determines which of the first cutting method and the second cutting method is to be adopted depending on the paper size or other conditions in the setting of the printing conditions received from the user. However, it may be fixed in advance to the first cutting method or the second cutting method.
[0056]
Here, processing of the printer driver 520 in the present embodiment will be described with reference to the flowchart of FIG.
[0057]
Prior to execution of printing, the user interface unit 521 of the printer driver 520 can accept setting of printing conditions from the user (S101). Note that the user can perform printing without setting print conditions, but in this case, the previously set print conditions are inherited.
[0058]
When the user interface unit 521 of the printer driver 520 receives a print condition setting command from the user via, for example, a menu command of the application 510, the display unit displays a print condition setting screen 300 as shown in FIG. 61, the setting of the printing condition is received from the user.
[0059]
As shown in FIG. 6, the print condition setting screen 300 is a screen for the user to set print conditions. For example, the paper size 301, the paper feeder 302, the paper type 303, the print quality 304, the auto cut designation 305, A borderless print designation 306 can be set. However, the items set on the printing condition setting screen 300 are not limited to these. For example, items relating to image processing that can be performed by the printer driver 520 may be included.
[0060]
Here, the paper size 301 designates the size of the image to be printed on the paper, and can be set, for example, by selecting A4, B4, postcard, etc. from the menu. The paper feeding device designates a device that feeds paper, and can be set by selecting roll paper, A4 tray, manual feed, and the like from a menu, for example. The paper type 303 designates the type of printing paper, and can be set, for example, by selecting plain paper, photographic paper, etc. from the menu. The print quality 304 designates the print quality, and can be set, for example, by selecting high resolution, high speed printing, etc. from the menu.
[0061]
The auto cut designation 305 designates whether or not to automatically cut the paper. Click the check box to specify the auto cut, and the paper is automatically cut as necessary at the time of printing. Is done. The borderless print designation 306 designates whether or not to perform printing (edgeless printing) in which the blank portion of the image is eliminated. By clicking the check box, borderless printing can be designated. At this time, the print data generation unit 522 realizes an image full of the paper size by generating image data larger.
[0062]
The print condition setting screen 300 includes an “OK” button 307 for ending the setting of the print condition and a “cancel” button 308 for canceling the setting. When the printer driver 520 receives a click on the “OK” button 307, the printer driver 520 stores the printing conditions set on the printing condition setting screen 300 in a nonvolatile manner and reflects them in the subsequent printing processing.
[0063]
In this embodiment, it is assumed that A4 is selected for the paper size 301, roll paper is selected for the paper feeder 302, and auto-cut 305 and marginless printing 306 are designated.
[0064]
When the printer driver 520 receives a print command from the user via the menu command or the like of the application 510, the printer driver 520 starts the printing process of the document being processed by the application 510 (S102).
[0065]
When the automatic cut 305 and the marginless printing 306 are designated, the printer driver 520 determines a cutting method according to a predetermined rule (S103). Here, the predetermined rule is, for example, that the vertical width S of the finished print size that can be obtained from the paper size 301 is compared with the distance W between the cutter 46 and the recording head 43. In other cases, the first cutting method can be adopted. Alternatively, the first cutting method can be adopted regardless of the setting of the paper size 301. However, the predetermined rules are not limited to these.
[0066]
Then, the printer driver 520 generates print data for printing the document and a cutting command for cutting the paper 22 by the cutting method determined in step S103, and transmits the generated print command to the printer 10 (S104).
[0067]
The cutting command for cutting the paper 22 by the cutting method determined in step S103 can include, for example, the designation of the cutting method and the instruction of the cutting position from the top of the paper 22. Alternatively, the setting information of the paper size 301 may be transmitted to the printer 10 so that the actual cutting position is controlled by the printer 10. In this case, it is particularly desirable in the first cutting method to transmit the paper size information prior to the print data for printing the document. This is because the printer 10 can perform the cutting process while receiving the print data, and can shorten the printing time.
[0068]
Next, processing of the printer 10 with a cutting function that has received the print data from the computer 50 will be described.
[0069]
FIG. 7 is a flowchart for explaining the processing of the printer 10 with a cutting function in the first cutting method.
[0070]
The printer 10 starts print processing by receiving print data including a cut method instruction from the computer 50 (S201). In this figure, it is assumed that the first cutting method is instructed.
[0071]
If the print data includes a cut position instruction, the paper is fed until the cutter 46 comes to the position. If the cutting position is specified by the paper size information, the paper is fed until the distance from the top of the paper 22 to the cutter 46 becomes equal to the vertical width of the paper size (S202).
[0072]
Then, the paper 22 is cut at that position (S203).
[0073]
Next, the paper is fed or returned to the position where the recording head 43 comes to the head of the paper 22 (strictly, the position slightly on the paper feed side from the recording head 43 for printing without margins) (S204).
[0074]
Then, printing by the recording head 46 is started for each line (S205), and paper is sent (S206). This is repeated until the image printing is completed (S207).
[0075]
When the image printing is completed, the paper is discharged (S208), and it is determined whether there is a next printing (S209). As a result, if there is next printing, the paper is fed again to the cutting position (S202), and if there is no next printing, the printing process is terminated (S210).
[0076]
FIG. 8 is a flowchart for explaining the processing of the printer 10 with a cutting function in the second cutting method.
[0077]
The printer 10 starts print processing upon receiving print data including a cut method instruction from the computer 50 (S301). In this figure, it is assumed that the second cutting method is instructed.
[0078]
First, paper feed or paper return is performed to a position where the recording head 43 comes to the head of the paper 22 (strictly speaking, a position slightly on the paper feed side from the recording head 43 in order to perform marginless printing) (S302).
[0079]
Then, printing by the recording head 43 is started (S303), and paper is sent (S304).
[0080]
When the paper is fed, the cutter 46 checks whether or not the cutting position of the paper 22 has come. (S305) The cut position is the position when the print data includes an instruction of the cut position. When the cut position is specified by the paper size information, the cut position is from the top of the paper 22 to the cutter 46. Is a position where the distance is equal to the vertical width of the paper size.
[0081]
As a result, when the cutter 46 is at the cutting position of the paper 22, the paper 22 is cut (S306).
[0082]
The processing from S303 is repeated until image printing is completed (S307).
[0083]
When the image printing is completed, the paper is discharged (S308), and it is determined whether there is a next printing (S309). As a result, if there is the next printing, the paper is fed to the printing start position (S302), and if there is no next printing, the printing process is terminated (S310).
[0084]
By doing so, it is possible to prevent the front and back images from entering, and also to cut the time between the images only, so that the printing time can be shortened compared to the two-cut method. Further, chips generated by the twice cutting method are not generated.
[0085]
Further, in the present embodiment, the cutter 46 is provided between the recording head 43 and the paper feeding device 33. For this reason, a portion where ink has not been sprayed is cut. Therefore, since it is not necessary to cut the ink after it dries, it is expected that the printing time is further shortened as compared with the conventional method in which the portion where the ink is sprayed is cut.
[0086]
【The invention's effect】
As described above, according to the present invention, it is possible to shorten the printing time in the printing apparatus that prevents the front and back images from entering in the marginless printing on the continuous paper.
[0087]
In addition, according to the present invention, it is possible to prevent generation of chips in the printing apparatus that prevents the front and rear images from entering in the marginless printing on the continuous paper.
