Description

  The present invention relates to a printer that transports continuous paper for photo printing using a paper feed roller.

  In some cases, a photograph is printed using a printer such as an inkjet printer. As recording media for photo printing, continuous paper (label paper, fanfold paper) having a configuration in which a photo printing label made of glossy paper is attached to a mount is known. In general, a printer conveys continuous paper using a paper feed roller.

  After the continuous paper is set in the printer or after the continuous paper has been printed, the continuous paper waits at a predetermined position on the conveyance path of the printer. In the standby state of the continuous paper, the continuous paper may be sandwiched between the paper feed roller and the driven roller, and the surface of the label portion may be left in contact with the driven roller. When the contact state between the label and the roller is long, the surface of the label (printing surface) may be marked with a roller, and the print quality may be deteriorated. In particular, since the marks on the rollers on the glossy paper are conspicuous, there is a possibility that the print quality of the photograph is greatly deteriorated.

  Patent Document 1 proposes a printer that can avoid the marks of the rollers. In the printer disclosed herein, the standby position of the paper is determined so that the margin between the print areas of the paper is sandwiched between the paper feed roller and the pressure roller.

JP 2003-54054 A

  In the printer disclosed in Patent Document 1, the blank portion of the paper is in contact with the roller in the print standby state. In the continuous paper, when the margin between the paper portions for one page of printing is wide, it is possible to prevent the roller marks from being attached to the printing area. However, when the margin portion is narrow, it is easy to form a state in which the surface of the paper is pressed against the roller in a state where the margin portion extends over the print area. In this case, it is impossible to reliably prevent the marks of the rollers from forming on the printing area of the paper. It is necessary to make the margin part sufficiently wide so that the roller does not contact the printing area. However, in this case, the print area of the paper portion for one page becomes narrow. Also, in the case of continuous paper for photo printing, labels (glossy paper) with a length matching the photo size such as L size are used, so it is necessary to leave only the blank area while leaving the printing area as it is. There is. If this is done, the proportion of non-printed areas increases, which is uneconomical.

  In view of the above, an object of the present invention is to propose a printer that does not cause a roller mark in the photo printing region of continuous paper for photo printing.

In order to solve the above problems, the printer of the present invention provides:
A printing section with a print head;
A transport unit that includes a paper feed roller and transports continuous paper to be printed ;
Have
The printing unit, the sheet portion of one page of the continuous paper, in the length direction of the continuous paper, the first print area for printing a photograph, and is printed separately in a second printing area to print text ,
The transport unit stops the paper feed roller in the second printing area when the continuous paper is positioned at a standby position.

  In the continuous paper printed by the printer of the present invention, a photo is printed in the first print area in the paper portion of each page, and in the second print area, photo attribute information (photo comments, shooting date and time, recording) The original file number / folder number, camera model information, etc.) are printed. This is convenient because it is possible to check the attribute information when editing, organizing, etc., after printing.

  Printing of information other than photographs, for example, printing of attribute information of photographs, is generally text printing and does not require print quality as high as photographs. In the printer of the present invention, paying attention to this point, the paper feed roller is positioned in the second print area where information such as photo attribute information is printed at the standby position of continuous paper. Thereby, it is possible to prevent the driven roller pressing the continuous paper from the front side against the paper feed roller from being left in close contact with the first printing region for photographic printing. Therefore, the first printing area for photographic printing does not have a roller mark, and the deterioration of the photographic print quality due to the roller mark can be reliably prevented.

  Further, unlike the case where the paper feed roller is positioned in a blank portion (a portion where printing is not performed) between the pages in the standby state of continuous paper, it is not necessary to make the blank portion sufficiently wide. That is, it is not necessary to make the margin portion sufficiently wide so that the roller does not contact the margin from the margin portion to the photo printing area.

  Here, the standby position of the continuous paper can be a position where the leading edge of the continuous paper or the trailing edge of the last printed page in the continuous paper is conveyed to a predetermined paper cutting position. When the continuous paper is set, the head of the set continuous paper is sent to the paper cutting position and enters a standby state. After the end of printing, the printer enters a standby state in which the trailing edge of the last printed page is positioned at the paper cutting position. In this state, when continuous paper is cut, a standby state in which the top of the unprinted continuous paper is positioned at the paper cutting position is entered, as in the case of setting continuous paper.

  When the continuous paper to be used is a continuous paper of a certain size and the second print area is continuous on the rear side in the transport direction of the continuous paper with respect to the first print area, as follows: The placement position of the paper feed roller is set. As a result, the paper feed roller can always be positioned in the second printing area at the standby position for continuous paper.

That is, the length of one page of the continuous paper is L, and the length of the paper portion of one page of the continuous paper from the rear end to the boundary between the first and second printing areas of the paper portion. Is A, B is the length from the trailing edge to the trailing edge of the second printing area, and X is the conveyance path length of the continuous paper from the paper cutting position to the paper feed roller. Set the position of the paper feed roller so that it falls within the following range.
(N × L) −A <X <(n × L) −B
Where n is a positive integer

  Next, the second print area of continuous paper is generally a text print area in which photo attribute information is printed.

  The print head includes a printing element array having a predetermined length arranged in the conveyance direction of the continuous paper by the conveyance unit, and the length of the second printing region in the conveyance direction is the printing element array. It is desirable that the length is shorter than the length in the transport direction.

  In the case of a serial type print head that performs printing while reciprocating in the direction orthogonal to the transport direction, printing in the second print area is completed in one pass (one forward or backward movement). . Therefore, a decrease in throughput due to printing in the text print area can be minimized.

  In the present invention, as the continuous paper, it is possible to use a long mount and a label paper provided with photographic paper attached to the surface of the mount at regular intervals. The first print area and the second print area are formed on the surface of the photographic paper along the length direction of the continuous paper.

  Further, as the continuous paper, a fan provided with perforations for partitioning the paper portions for one page and engagement holes formed at a constant pitch in the paper length direction along both edges in the paper width direction. Fold paper can be used.

  In this case, it is preferable that the transport unit includes a tractor unit that engages with the engagement hole of the fanfold paper and transports the fanfold paper toward the paper feed roller. In this case, the standby position can be selectively set to a position where the head of the fanfold paper is retracted to the space between the paper feed roller and the tractor unit. By pulling the fanfold paper back into the printer, it is possible to prevent the leading portion of the fanfold paper from being exposed on the discharge side of the printer.

Next, in the present invention, the transport unit is configured to perform the standby based on each length of the first print area and the second print area in the transport direction of the continuous paper and detection information of the transport position of the continuous paper. It is desirable that the standby position can be set so that the paper feed roller stops at the second printing area at the position.

  In this way, even if the type (size) of the continuous paper to be set is changed, the continuous paper can be kept on standby so that the paper feed roller is always positioned in the second printing area.

  FIG. 4 is an explanatory diagram showing the internal structure of the printer 1. With reference to FIG. 3 and FIG. 4, a paper conveyance path formed inside the printer 1 will be described. As shown by a thick line in FIG. 4, a paper conveyance path 21 extending in the printer width direction X is formed inside the printer main body 3. The paper transport path 21 extends from the paper insertion opening 12 to the paper discharge opening 14.

  The lower surface of the paper transport path 21 has an upstream paper guide 22 extending from the paper insertion opening 12 to the middle of the printer width direction X toward the left of the printer, and a platen 23 extending continuously from the upstream paper guide 22. , And the discharge tray 15. The platen 23 is composed of divided platens arranged at a predetermined interval along a direction orthogonal to the paper transport direction, that is, the front-rear direction Y of the printer.

  Above the platen 23, a carriage guide shaft 24 that extends horizontally in the longitudinal direction Y of the printer is disposed. The carriage guide shaft 24 is supported by the mechanism frame 3 a of the printer body 3. A head carriage 25 is attached to the carriage guide shaft 24 in a slidable state. A print head 26 is mounted on the head carriage 25. The print head 26 (i.e., the jet head) has a downward posture so that the nozzle surface faces the platen 23 that defines the printing position. The head carriage 25 can be reciprocated in the front-rear direction Y of the printer along the carriage guide shaft 24 by a known carriage drive mechanism 25a including a motor 25b and a belt / pulley mechanism 25c.

  The head carriage 25 has a home position at the front end of the printer shown in FIG. 3, and waits at the home position during printing standby. A head maintenance mechanism 27 is mounted below the print head 26 mounted on the head carriage 25 located at the home position. The head maintenance mechanism 27 is equipped with a nozzle cap (not shown) for capping the nozzle surface of the print head 26, a suction mechanism (not shown) for sucking ink from each nozzle, and the like. Head maintenance operation is performed to prevent nozzle clogging and to perform maintenance operation to eliminate nozzle clogging. An ink cartridge mounting portion 28 is formed below the head maintenance mechanism 27. An ink cartridge mounting portion 29 is also formed at a portion of the carriage guide shaft 24 opposite to the home position.

  Inside the printer main body 3, a paper feed roller 31 a and a driven roller 31 b for feeding the label paper 2 toward the print position are arranged between the print position of the print head 26 and the tractor unit 13. As shown by a broken line in FIG. 4, the paper feed roller 31a transmits the driving force from the paper feed motor 32 via a driving force transmission mechanism 33 including a gear train. A paper discharge roller 34a and a driven roller 34b for discharging the printed label paper 2 are provided at a site on the left side of the printer with respect to the printing position defined by the platen 23 (a site downstream in the paper transport direction). Is arranged. As shown by a broken line in FIG. 4, the driving force from the paper discharge motor 35 is transmitted to the paper discharge roller 34a via a driving force transmission mechanism 36 formed of a gear train.

  The tractor unit 13 includes a tractor pin 42 that circulates along an oval circulation path. The tractor pins 42 move while sequentially engaging with sprocket holes 2c (see FIG. 1) formed on both side edges of the label paper 2 in the paper width direction, whereby the label paper 2 is directed toward the printing position. Sent out. A driving force from the tractor driving motor 43 is transmitted to the tractor unit 13 via a driving force transmission mechanism 44 including a gear train.

  FIG. 5 is a schematic block diagram illustrating a control system of the printer 1. The control system is configured around a control unit 50 including a computer. The control unit 50 includes an input / output unit 51, a print data generation unit 52, a conveyance control unit 53, a print control unit 54, an image processing unit 55, and the like. The LCD panel 4 and the card reader 56 are connected to the input / output unit 51.

  The LCD panel 4 has an input function such as a touch panel, and various commands such as a print command are input to the control unit 50 via the input / output unit 51. Also, print information (photograph, attribute information) stored in the memory card 57 inserted from the card insertion slot 18 is taken in via the card reader 56 and the input / output unit 51. The captured print information is processed by the image processing unit 55. For example, the paper information of the label paper 2 is stored and held in advance in the image processing unit 55, and based on this, the photo print information and attribute print information to be printed in the first and second print areas 2B and 2C are edited. Do. Based on the editing information, the print data generation unit 52 generates print data for printing a photograph and attribute information by the print head 26.

  When a print command is input via the input / output unit 51, the conveyance control unit 53 drives the tractor drive motor 43, the paper feed motor 32, and the paper discharge motor 35 via the motor drivers 61, 62, and 63. The label paper 2 is transported. In synchronization with the conveyance of the label paper 2, the print control unit 54 drives the carriage motor 25 b via the motor driver 64 to move the head carriage 25 in the paper width direction, and via the head driver 65. The print head 26 is driven to perform print operation of print data.

  As described above, the print control unit 54, the motor driver 64, the carriage motor 25b, the head carriage 25, the head driver 65, the print head 26, and the like constitute the print unit of the printer 1. Further, the conveyance control unit 53, the motor drivers 61 to 63, the motors 32 and 35, the tractor unit 13, and the like constitute a conveyance unit of the printer 1.

  In the printer 1 of this example, in the paper portion 2A of each page of the label paper 2, a photo is printed in the first print area 2B, and in the second print area 2C, photo attribute information (photo comments, shooting date and time) Recording source file number / folder number, camera model information, etc.). The printing of the attribute information of the photograph is text printing, and print quality as high as that of the photograph is not required. The control unit 50 of the printer 1 conveys the label paper 2 at the standby position of the label paper 2 so that the paper feed roller 31a and the driven roller 31b stop in the second print area 2C where the photo attribute information is printed. I have control. Thereby, it is possible to prevent the driven roller 31b that presses the label paper 2 from the back side against the paper feed roller 31a from being left in close contact with the first printing region 2B for photographic printing. Therefore, it is possible to prevent the follower roller 31b from being marked by the first printing region 2B for photographic printing, and the photographic printing quality from being deteriorated.

(Label paper standby position, paper feed roller placement position)
Here, when the label paper 2 is set, the standby position of the label paper 2 is a position where the head of the label paper 2 coincides with the paper cutting position 15a. Further, the standby position of the label paper 2 after the printing is finished is a position where the rear end of the last printed page in the label paper 2 coincides with the paper cutting position 15a. The label paper 2 stopped at this position is cut along the perforation 2d located at the paper cutting position 15a by the operator.

  In this example, the label paper 2 to be used is of a certain size, and the second printing area 2C is continuous to the rear side (upstream side) in the transport direction with respect to the first printing area 2B (see FIG. 1). In this case, the arrangement positions of the paper feed roller 31a and the driven roller 31b in the conveyance direction on the paper conveyance path 21 may be set as follows. Thereby, at the standby position of the label paper 2, the paper feed roller 31a and the driven roller 31b can always be positioned on the second printing area 2C.

FIG. 6 is an explanatory diagram showing an arrangement position of the paper feed roller 31 a in the transport path 21. With reference to this figure, the arrangement position (position of the roller shaft center) of the paper feed roller 31a will be described. First, let L be the sheet length for one page of the label sheet 2. Further, in the paper portion 2A for one page of the label paper 2, the length from the rear end to the boundary between the first and second printing areas 2B and 2C of the paper portion 2A is A, and the length from the rear end of the paper portion 2A is 2 Let B be the length to the rear end of the printing area 2C. Further, let X be the conveyance path length of the label paper 2 between the paper cutting position 15a and the center of the roller axis of the paper feed roller 31a. In this case, the arrangement position of the paper feed roller 31a (driven roller 31b) may be set so that the conveyance path length X is within the following range.
(N × L) −A <X <(n × L) −B
Where n is a positive integer

  By determining the arrangement positions of the paper feed roller 31a and the driven roller 31b as described above, these rollers are positioned on the second printing area 2C of the label paper 2 when the label paper 2 is in the standby state. Therefore, in the standby state, it is possible to reliably prevent the roller from being left in close contact with the first printing region 2B, which is the photo printing region, so that the first printing region 2B is not marked with a roller.

  Next, in the printer 1 of the present example, the leading position of the label paper 2 can be set to a position where the head of the label paper 2 is retracted to between the paper feed roller 31 a and the tractor unit 13 as the standby position of the label paper 2. In other words, at the standby position, the leading portion of the label sheet 2 remains exposed on the discharge tray 15. Based on the input command from the LCD panel 4, the control unit 50 positions the label sheet 2 at a standby position where the label sheet 2 is back-fed to a position deviated rearward from the sheet feed roller 31a. Thereby, it is possible to avoid a state in which the label paper 2 is exposed to the outside. Further, none of the paper feed roller 31a, the driven roller 31b, the paper discharge roller 34a, and the driven roller 34b are positioned on the first printing area 2B of the label paper 2.

  FIG. 7 is an explanatory diagram showing the position of the label sheet 2 on the sheet conveyance path 21. As shown in FIG. 7A, when the label paper 2 is set, the head of the label paper 2 is in a standby state in which it is positioned at the cutting start position 15a. At the start of printing, as shown in FIG. 7B, the paper portion 2A (1) of the first page of the label paper 2 is back-fed to the printing position by the print head 26 and positioned. After the printing is finished, as shown in FIG. 7C, the rear end (perforation 2d) of the paper portion 2A (n) of the last page after the printing is positioned at the paper cutting position 15a. In this state, the printed trailing edge of the label paper 2 is cut along the perforation 2d by the operator, and the paper portion of the first page of the label paper 2 after cutting is cut as shown in FIG. The head of 2A (n + 1) is in the standby state positioned at the paper cutting position 15a. When a standby state in which the label sheet 2 is pulled into the printer 1 is instructed by an input operation by the operator, the label sheet 2 is back-fed. Thereby, as shown in FIG. 7E, the label paper 2 is in a standby state in which the head of the paper portion 2A (n + 1) of the first page is positioned at a position between the paper feed roller 31a and the tractor unit 13. become.

  Here, when different sizes and types of label paper 2 are used, the standby position can be controlled according to the type of label paper. For example, the control unit 50 stores and holds information related to the type of label paper in advance. When the type of the label paper 2 is input, the control unit 50 is in a standby state based on the corresponding one-page paper length, the first and second print area lengths, and the label paper 2 transport position. The conveyance control may be performed so that the second printing area 2C of the label paper 2 is positioned on the paper feed roller 31a and the driven roller 31b. The transport position of the label paper 2 can be monitored using, for example, a sensor disposed at a position behind the paper feed roller 31a (upstream in the transport direction). That is, it is possible to detect that the leading edge of the label sheet 2 has passed by the sensor, and to monitor the leading position of the label sheet 2 based on the carry amount from the detection time. In this way, even if the type (size) of the label paper to be set is changed, the label paper 2 is kept on standby so that the second printing area 2C is always located on the paper feed roller 31a and the driven roller 31b. Can be made.

Next, it is desirable to set the length of the second printing area 2C of the label paper 2 in the transport direction as follows. That is, in the print head 26, when the length in the paper transport direction in the nozzle row arranged on the nozzle surface is W (26), the length W (2C) of the second print region 2C is as follows: It is shorter than the length W (26) of the nozzle row.
W (2C) <W (26)

  In this way, the print head 26 can end the printing of the second print area C by a one-pass (one forward or backward) printing operation. Therefore, it is possible to minimize a decrease in throughput caused by printing the photo attribute information in the second print area 2C.
