  However, in the conventional recording apparatus, when the length of the recording paper to be cut is shorter than the distance from the cutting position to the discharge port, the cut recording paper may not be pushed out well due to contact with the inside of the discharge port. is there. As a result, the recording paper may stay in the conveyance path downstream from the cutter device described above, and a jam may occur.

  In the first place, there is a basic problem that the user cannot take out the printed matter unless the leading edge of the cut recording paper comes out of the discharge port. For this reason, it is conceivable to operate the cutter device after transporting the recording paper to such a length that the leading edge of the recording paper exits from the discharge port, but in this case, the unrecorded blank portion becomes large. Another problem arises.

  The present invention has been made in view of the above-described conventional example. Even when a recording medium to be cut is short, the recording medium cutting method is changed, and wasteful consumption of the recording medium is suppressed, and the recording medium is moved into the apparatus.

And changing means for changing to a partial cut even if the instruction by the user is a full cut according to whether or not there is.

  According to another aspect of the present invention, there is provided a print data transmission apparatus that adds cut setting information to print data and transmits the print data to a recording apparatus, and the recording medium is fully cut or partially printed in units of print data pages. According to selection means for selecting whether to cut, and whether the length of the printed page from the full cut to the next full cut is less than a predetermined minimum cut length when full cut is selected by the selection means And a change means for changing full cut selection to partial cut.

  According to another aspect of the present invention, a recording unit that performs recording on a continuous recording medium, a conveying unit that conveys the recording medium, and a conveyance direction of the recording medium by the conveying unit, the downstream side of the recording unit. And a cutting device control method provided with a cutting means capable of cutting the recording medium by a full cut or a partial cut according to an instruction from a user, from the previous full cut by the cutting means According to whether or not the conveyance distance of the recording medium by the conveyance means is less than a predetermined minimum cut length, control is performed so as to change to a partial cut even if the instruction by the user is a full cut. A control method is provided.

  Hereinafter, preferred embodiments of the present invention will be described more specifically and in detail with reference to the accompanying drawings. However, the present invention is not limited to the examples described below, and there may be changes and additions within the scope not departing from the gist of the present invention.

  In this specification, “recording” (sometimes referred to as “printing”) is not limited to the case of forming significant information such as characters and graphics, but may be significant. Furthermore, it also represents a case where an image, a pattern, a pattern, or the like is widely formed on a recording medium or a medium is processed regardless of whether or not it is manifested so that a human can perceive it visually.

<Configuration of Recording Apparatus (FIGS. 1-2)>
FIG. 1 is a side sectional view showing an outline of the internal structure of a recording apparatus 100 equipped with an ink jet recording head according to a typical embodiment of the present invention.

  As shown in FIG. 1, a recording apparatus 100 and a host computer (hereinafter referred to as host) 101 are connected via a USB cable 111. The recording apparatus 100 includes four full-line recording heads (hereinafter referred to as recording heads) 102 to 105 in which a plurality of nozzles are arranged over the entire width of a recording medium such as recording paper, along the conveyance direction of the recording paper. .

  Each of the four recording heads 102 to 105 performs image recording by ejecting black ink, cyan ink, magenta ink, and yellow ink, and prints a full-color image with four colors of ink ejected from the four recording heads. The four recording heads 102 to 105 can be replaced for each recording head.

  The host 101 transmits density image data generated and separated into a black (Bk) component, a cyan (C) component, a magenta (M) component, and a yellow (Y) component corresponding to four colors of ink. Receiving the image data, the recording apparatus 100 feeds the roll-shaped recording paper 106, conveys it while being sandwiched between the pressing roller 107 and the conveyor belt 108, and sequentially prints with each color ink by the recording heads 102 to 105. I do. In the printing, the leading edge of the recording paper 106 to be printed is detected by the paper leading edge detection sensor 109, and each color ink is ejected from the recording heads 102 to 105 onto the recording paper according to the timing determined based on the moving distance therefrom. Is done. Further, after the printing operation is completed, the cutter device 110 is driven at a timing when the trailing edge of the print page reaches the cutter device 110 provided at a certain distance downstream in the conveyance direction of the recording paper, and the recording paper is cut. To discharge the printed matter.

  FIG. 2 is a block diagram showing a control configuration of the recording apparatus shown in FIG.

  As shown in FIG. 2, a CPU 201 provided in the controller 200 of the recording apparatus 100 executes a control program stored in a ROM 202 by using a RAM 203 as a work area to control each component. In addition, the controller 200 uses the RAM 203 as a work area for various data processing and a reception buffer, and uses the image memory 204 as an image development unit. Further, the controller 200 includes a head driving circuit 208 that drives the recording heads 102 to 105, and a motor driver 210 that drives various motors 209 that control the cleaning operation and the recording operation for keeping each recording head in an optimum state for recording. Is provided. Furthermore, an ASIC 205 for controlling a sensor 211 and the like for controlling various operations and detecting a recording sheet is provided.

  The recording apparatus 100 also includes a USB controller 212 that receives image data, a cleaning command, and the like transmitted from the host 101 via the USB cable 111, and operates according to the received various command instructions. However, the interface with the host is not limited to USB, and may be connected to the host 101 via a wired or wireless network.

  3 is a side sectional view showing a schematic configuration of an example of the cutter device 110 of the recording apparatus shown in FIG. FIG. 3 is a diagram viewed from the conveyance direction of the recording paper, and is viewed from a direction orthogonal to FIG.

  As shown in FIG. 3, the cutter device 110 includes a fixed blade 301 and a movable blade 302, and the movable blade 302 is driven toward the fixed blade 301 by a drive mechanism (not shown). The movable blade 302 has a groove 303 at the center. When the groove 303 of the movable blade 302 is driven to a position exceeding the edge 301e of the fixed blade 301, full cut is performed, and when the groove 303 of the movable blade 302 is driven to a position not exceeding the edge 301e of the fixed blade 301, partial cut is performed.

  As described above, the cutter device 110 can switch between a full cut that completely cuts the recording paper and a partial cut that is a partial cut that cuts only a part of the recording paper depending on the amount of movement of the movable blade 302. .

  Note that the mechanism of the cutter device 110 is not limited to the above-described configuration. The present invention can be applied if a cutter having functions of both partial cut and full cut is provided.

  Next, an embodiment of cut control when printing on continuous recording paper using the recording apparatus having the above-described configuration will be described.

  FIG. 4 is a diagram illustrating a cut instruction according to the first embodiment.

  When a print job is transmitted from the host 101, a cut parameter indicating the sheet length of each page and whether or not the page is cut is added to the print job.

  FIG. 4A shows an example of a print job for all six pages, and shows that two pages having a sheet length of 40 mm and 20 mm are cut as a set and cut every two pages. FIG. 4B also shows an example of a print job for all six pages, and shows that each page is cut every page with a paper length of 10 mm.

  Here, the presence or absence of cutting is specified by the print job parameters according to the user's settings, but the setting of the presence / absence of cutting is not limited to this, and depending on the use of the recording apparatus, no user setting means is provided. Basically, it may be configured to cut every page.

  FIG. 5 is a diagram schematically showing a state in which the cut paper stays inside the cutter device 110.

  As described above, a certain distance exists between the cutting position of the cutter device 110 and the discharge port 500 of the recording paper 106. Therefore, as shown in FIG. 5, when the paper length of the recording page is very short, the cut recording paper 501 may stay inside without being discharged from the discharge port 500. For this reason, there is a minimum paper length necessary for reliably discharging printed cut recording paper out of the apparatus. In this embodiment, it is defined as the minimum cut length Lmin, and here the length is 15 mm. Note that the minimum cut length Lmin may be set to an optimum value depending on the use and operation method of the recording apparatus. For example, the minimum cut length may be a length that allows the user to take out the recording paper from the discharge port 500 of the recording apparatus even if the cut recording paper stays on the spot. That is, a length obtained by adding a predetermined amount to the length from the cutting position to the discharge port 500 may be used. Alternatively, the length at which the cut recording paper naturally falls may be set as the minimum cut length.

  In consideration of the above requirements, in this embodiment, when a cut instruction is received at a cut interval shorter than the minimum cut length Lmin, the cut process is changed to a partial cut process.

  FIG. 6 is a side sectional view of the cutter device 110 schematically showing a state in which the partially cut sheet is discharged.

  Partial cutting is performed with a part of the recording paper connected. For this reason, as shown in FIG. 6, the partially cut recording paper 600 is continuously printed on the succeeding recording paper 601 even if the recording paper is not discharged from the discharge port 500 at that time, so that the recording paper 600 is printed. The recording paper 600 that has been pushed out and printed from the discharge port 500 can be acquired.

  In addition, since the partial cut is a state in which a part of the recording paper is connected, the preceding page can be prevented from being lifted, and the preceding page can be reliably pushed out on the succeeding page. Further, since it is easy for the user to cut a part of the recording paper, the user can easily obtain printed recording paper for each page.

  On the other hand, if there is no cut, the user needs to cut page by page, which is troublesome for some users. Therefore, there is an advantage in performing the partial cut. Even if the operation cost is increased, it is possible to switch to an operation without cutting if a recording sheet with a perforation is used.

  FIG. 7 is a flowchart showing print control including change processing to partial cut.

  In step S700, the recording apparatus 100 that has received the print job first resets the transport distance from the previous cut for calculating the cut interval. In step S701, the first page is printed, and in step S702, the sheet length of the page is added to the transport distance from the previous cut.

  In step S703, it is checked whether there is a full cut instruction in the cut parameter added to the print job. If it is determined that there is a full cut instruction, the process advances to step S704 to compare the transport distance (L) from the previous cut with the minimum cut length Lmin. Here, if the transport distance (L) from the previous cut is longer than the minimum cut length Lmin (L ≧ Lmin), the recording paper is discharged without any problem, so the process proceeds to step S705, and the full cut is performed as instructed by the user. Execute. In step S706, the conveyance distance (L) from the previous cut is reset. Thereafter, the process proceeds to step S708. On the other hand, if the transport distance (L) from the previous cut is less than the minimum cut length Lmin (L <Lmin), the process proceeds to step S707 to execute a partial cut. Thereafter, the process proceeds to step S708.

  In step S708, the process checks whether there is a subsequent page to be printed in the print job. If it is determined that there is a subsequent page, the process returns to step S701, and the above-described printing process is repeated again. On the other hand, if it is determined that there is no subsequent page and all printing of the print job is completed, the process proceeds to step S709.

  In step S709, the cutting status of the last page is confirmed. Here, when it is determined that the last page has been partially cut, since all the printed recording sheets have not been acquired, the process proceeds to step S710. In step S710, the recording paper is finally separated from the recording paper in the recording apparatus and discharged to the outside of the apparatus. Therefore, until the transport distance (L) from the previous cut exceeds the minimum cut length Lmin, that is, the leading edge of the recording paper is The recording paper is additionally conveyed until it goes out of the discharge port 500. Thereafter, a full cut is performed in step S711, and the process is terminated. On the other hand, if it is determined that the last page is not a partial cut, the process ends.

  Here, for convenience of explanation, after printing is completed for each page, the rear end side of the printed recording page is cut and the next page is printed. However, in practice, since the leading edge of the next page has already reached the position of the recording head at the timing when the trailing edge of the first page is positioned in the cutting mechanism, that is, the timing of performing the cutting process, the printing process is performed in parallel. Yes. However, although parallel processing is actually performed, there is substantially no difference from the print control described above.

  FIG. 8 is a diagram illustrating a result of the cut process changed by executing the print control. FIG. 8 shows the result of the cutting process corresponding to the cutting instruction shown in FIG.

  First, FIG. 8A shows cut control when a print job to which the cut instruction shown in FIG. 4A is added is printed. According to FIG. 8A, the conveyance distance is 40 + 20 = 60 mm at the time of the second page which is the first cut timing, and the full cut is performed as set because the minimum cut length (here 15 mm) is reached. Similarly, for the third to sixth pages, the full cut is executed as instructed.

  On the other hand, FIG. 8B shows the cut control when the print job to which the cut instruction shown in FIG. 4B is added is printed. According to FIG. 8B, since the transport distance is 10 mm at the time of the first page which is the first cut timing and does not reach the minimum cut length of 15 mm, the full cut process is changed to the partial cut process. . Subsequently, on the second page, the transport distance is 10 mm + 10 mm = 20 mm, which exceeds the minimum cut length of 15 mm, so that a full cut is performed as specified. Similarly, the third and fifth pages are partially cut, and the fourth and sixth pages are full cut.

  The second page and the fourth page may be changed to partial cuts, and only the last page may be left as a full cut. Further, the full cut may not be performed even if the transport distance exceeds the minimum cut length, and the full cut may be performed for each arbitrary page that is longer than the minimum cut length.

  FIG. 9 is a schematic diagram showing a printed matter obtained by executing a print job and cut control.

  FIG. 9A shows a desired printed matter in the print job shown in FIG. As shown in FIG. 9 (a), the desired printed matter is one in which one page has a paper length of 10 mm and all six pages are cut.

  On the other hand, FIG. 9B shows a printed matter obtained by performing cut control as shown in FIG. 8B for the print job shown in FIG. 4B. As shown in FIG. 9 (b), although the cut interval is every two pages, the uncut pages are also partially cut, so they can be torn without using tools, etc. A desired printed matter can be obtained.

  Therefore, according to the embodiment described above, even when the paper length is short, the full cut operation is changed to the partial cut operation to discharge the printed matter without staying in the apparatus, and a desired printed matter can be obtained by a simpler operation. be able to. Further, according to this embodiment, there is an advantage that the recording paper is not wasted because only the full cut operation is changed to the partial cut operation, and no extra conveyance of the recording medium is performed.

  Note that, when the full cut is changed to the partial cut, the user himself / herself needs to tear off the recording paper, so the operation panel of the recording apparatus may be notified of the change to the partial cut.

  In the first embodiment, the cut interval is determined in the print job by the print control of the recording apparatus, and the partial cut is changed. However, such a change is not limited thereto. For example, before sending the print data on the print data transmission device (host) side, notification for prompting the determination of the cut interval and the change of the cutting method may be performed. In this embodiment, an example of determination of a cut interval and a notification of a change in a cutting method will be described.

  FIG. 10 is a flowchart illustrating cut interval determination and partial cut change processing executed when print data is generated according to the second embodiment.

  FIG. 11 is a diagram illustrating a display example of cut settings in the print data transmission apparatus.

  FIG. 11A shows an example of full cut setting, and FIG. 11B shows an example of partial cut setting. Each cut interval can be selected from only the last page, each page, or a specified number of sheets.

  First, in step S1000, after cutting interval information is reset, in step S1001, sheet length information for the Nth page is acquired. Here, the first page after reset is one page (N = 1). In step S1002, this is added to the cut interval. In step S1003, the Nth page cut parameter is acquired, and it is checked whether or not there is a cut instruction in the cut parameter.

  If it is determined that there is a full cut instruction, the process advances to step S1004 to check whether the cut interval is less than the minimum cut length Lmin. If it is determined that the cut interval is equal to or greater than the minimum cut length, the process proceeds to step S1005, the cut instruction is not changed, the cut interval is reset, and then the process proceeds to step S1007. On the other hand, if it is determined that the cut interval is less than the minimum cut length, the process advances to step S1006 to change the cut instruction to a partial cut instruction. Thereafter, processing proceeds to step S1007.

  If it is determined in step S1003 that there is no full cut instruction on the Nth page, the process advances to step S1007. In step S1007, it is checked whether there is a subsequent page to be printed. If it is determined that there is a subsequent page, the process returns to step S1001 to perform the process for the next page, and the second page (N = 2) and the third page (N = 3) thereafter. ) ... and repeat the above process to determine all pages. On the other hand, if it is determined that there is no subsequent page, the process ends.

  If the instruction is changed to the partial cut instruction in step S1006, the following display is performed.

  In the setting screen shown in FIG. 11A, when the full cut for each page is selected, the cut interval for one page is less than the minimum cut length Lmin, and the cut interval for every three pages is not less than the minimum cut length Lmin. If there is, the following processing is performed. That is, as shown in FIG. 12, a message notifying that the full cut is impossible for each page is displayed. When the user presses OK in response to this display, the setting shown in FIG. 11A is changed to “full cut at specified number interval, 3 pages”, and the trailing edge of the first page and second page is Change to partial cut.

  In this embodiment, as described above, the full cut is changed to the partial cut based on the predetermined minimum cut length, and the interval for performing the full cut is changed. Therefore, it is desirable to notify the user in advance that the cutting process may be changed to partial cutting. Further, since the paper length and the cut setting of the print job are set by the setting of the printer driver of the host or the like, it can be determined whether or not the change to the partial cut is performed under the set printing conditions.

  Accordingly, when the user clicks (or presses or taps) the OK button 1101 on the cut setting screen 1100 shown in FIG. 11 displayed on the host display, the paper length and the designated cut interval are changed to partial cut. It is determined whether a change is made. Then, when a change to a partial cut is made, the user is notified in advance through a message screen 1200 as shown in FIG.

  By executing the processing described above on the host, a print job in which the cut instruction at intervals shorter than the minimum cut length is changed to partial cut is generated, and printing is performed without causing recording paper retention or jamming inside the recording device. And cuts can be made.

  In the flowchart described above, attention is paid only to the change of the cut instruction in the process of generating the print data. However, in actuality, the process is executed as a part of various processes necessary for generating the print data.

  Therefore, according to the embodiment described above, even when the paper length is short, it is possible to reduce the processing load on the recording apparatus side by executing the process of changing the full cut instruction to the partial cut instruction on the host. . In addition, since the user can change the setting on the host side, more user-friendly processing can be realized. In any case, according to this embodiment, the recorded matter can be discharged without staying in the recording apparatus, and a desired printed matter can be obtained by a simpler operation.

  In the embodiment described above, the full cut operation is changed to the partial cut operation. However, the replacement process may not be a partial cut. For example, when a perforation cutting mechanism capable of cutting a sheet into a perforation is provided, the full cut may be replaced with a perforation cut.

  In the embodiment described above, the cutting process is replaced by the recording apparatus or the host computer. However, the apparatus for performing the processing is not limited to this, and is a part of the recording system that can recognize the cutting interval. Any form is acceptable.

  As described above, even when the cut interval is short, the full cut operation is replaced with a means for cutting a part of the paper such as a partial cut, so that the recorded matter is discharged without staying, and the desired operation can be performed with a simpler operation. It is possible to obtain printed matter.

  In the embodiment described above, the recording apparatus using the full line recording head has been described as an example, but the present invention is not limited thereto. For example, the recording head may be a recording apparatus that performs recording by reciprocally moving the recording head in a direction perpendicular to the recording medium conveyance direction and intermittently conveying the recording paper accordingly. Alternatively, it may be a transfer type printer that forms an image by transferring the ink applied to the ink holding member onto a recording sheet.

  In the embodiment described above, the cutter device and the recording device are externally attached. However, the present invention is not limited to this, and the cutter device is built in the recording device. It may be configured.
