The head 5 (corresponds to the “recorder” of the present disclosure) is of an inkjet type, and has a plurality of nozzles (not shown) formed in a lower surface. When the sheet P conveyed by the conveyance mechanism 3 passes through a position facing the lower surface of the head 5, a driver IC 50 (refer to
As shown in
The control device 100 is further communicatively connected to a PC (Personal Computer) 200 (corresponds to the “external apparatus” of the present disclosure). In the PC 200, a general-purpose printer driver (for example, a printer driver capable of converting image data received from application software into image data in a vector format expressed in PDL (Page Description Language) and outputting the image data) is installed. The PDL is, for example, PCLXL, PCL5, PostScript, PDF, XPS, or the like.
The control device 100 executes recording processing of, based on a recording command (including image data) received from the PC 200 and data input from the interface 150, controlling the conveying motor 30 and the driver IC 50 (further, the cutting motor 40 when performing a recording on the roll sheet Pr) to record an image on the sheet P.
The control device 100 includes two random access memories (RAMs) 101 and 102, a read only memory (ROM) 103, a raster image processor (RIP) unit 111, and an image processing unit 112. The RIP unit 111 and the image processing unit 112 correspond to the “controller” of the present disclosure, and particularly, the RIP unit 111 corresponds to the “first controller” of the present disclosure, and the image processing unit 112 corresponds to the “second controller” of the present disclosure. The second RAM 102 corresponds to the “temporary memory” of the present disclosure.
The first RAM 101 temporarily stores a recording command received from the PC 200.
The RIP unit 111 reads out the recording command from the first RAM 101, and generates recording data (density data of each color of RGB in a raster format (bitmap format)), based on image data (image data in a vector format expressed in PDL (Page Description Language)) included in the recording command. The RIP unit 111 writes the generated recording data into the second RAM 102.
The image processing unit 112 reads out the recording data from the second RAM 102, converts the recording data (i.e., the density data of each color of RGB output from the RIP unit 111) into ejection data (data representing an amount of ejection in each ejection period for each nozzle), and executes the recording processing based on the ejection data.
The ROM 103 stores programs and data for the RIP unit 111 and the image processing unit 112 to perform various types of controls.
The RIP unit 111 is configured by, for example, software mainly composed of a program that operates on a CPU. Alternatively, the RIP unit 111 may be configured by hardware such as an ASIC. Alternatively, the RIP unit 111 may be configured to operate by using both software processing and hardware processing.
Similarly to the RIP unit 111, the image processing unit 112 may also be configured by software mainly composed of a program that operates on the CPU, or may be configured by hardware such as an ASIC, or may be configured to operate by using both software processing and hardware processing.
Next, processing that is executed by the RIP unit 111 is described with reference to
The RIP unit 111 first determines whether a recording command has been received from the PC 200 (S1).
The processing of receiving a recording command from the PC 200 corresponds to the “receiving processing” of the present disclosure. The recording command includes image data, as described above. The image data includes one or a plurality of images, each of which is to be recorded on one page. One image is included in one page. The recording command received from the PC 200 is stored in the first RAM 101.
If it is determined that the recording command has not been received from the PC 200 (S1: NO), the RIP unit 111 repeats the processing of S1.
If it is determined that the recording command has been received from the PC 200 (S1: YES), the RIP unit 111 reads out the recording command from the first RAM 101 and determines whether the image data included in the recording command includes a plurality of images (S2).
If it is determined that the image data included in the recording command includes a plurality of images (S2: YES), the RIP unit 111 determines whether to perform a combination-recording (S3: first determination processing). The combination-recording refers to processing in which a plurality of images are aligned in the conveyance direction and recorded on a single sheet P. The user of the printer 1 can perform an input as to whether to perform combination-recording and an input of the number of images to be combined in the combination-recording to the interface 150. The interface 150 transmits, to the control device 100, data indicating whether to perform the combination-recording, data indicating the number of images to be combined, and the like, based on the user input. The RIP unit 111 performs the determination in S3, based on the data received from the interface 150.
If it is determined that the combination-recording is to be performed (S3: YES), the RIP unit 111 generates selection data indicating selection of the roll sheet Pr as a recording target (S4). The selection data is written to the second RAM 102.
On the other hand, if it is determined that the image data included in the recording command does not include a plurality of images (i.e., the image data includes one image) (S2: NO), or if it is determined that the combination-recording is not to be performed (S3: NO), the RIP unit 111 generates selection data indicating selection of the cut sheet Pc as a recording target (S5). The selection data is written to the second RAM 102.
After S4, the RIP unit 111 determines whether the number of images included in the image data is larger than the number of images input to the interface 150 (the number of images to be combined instructed by the user) (S6).
If the number of images included in the image data is larger than the number of images input to the interface 150 (S6: YES), the RIP unit 111 executes notification processing of, via the notification unit 160 (refer to
In S7, the RIP unit 111 may cause the display constituting the notification unit 160 to output an image indicating the above effect, or may cause the speaker constituting the notification unit 160 to output audio indicating the above effect.
After S7, the RIP unit 111 ends the routine. When re-input to the interface 150 is performed, the RIP unit 111 resumes the routine shown in
If the number of images included in the image data is not larger than the number of images input to the interface 150 (S6: NO), i.e., if the number of images included in the image data is equal to the number of images input to the interface 150, or, if the number of images included in the image data is smaller than the number of images input to the interface 150, the RIP unit 111 determines whether an available capacity of the second RAM 102 is equal to or larger than a predetermined amount X (S8: second determination processing).
If it is determined that the available capacity of the second RAM 102 is equal to or larger than the predetermined amount X (S8: YES), the RIP unit 111 generates recording data relating to a plurality of images aligned in the conveyance direction, based on the image data included in the recording command (generation processing), and writes the generated recording data into the second RAM 102 (output processing). At this time, the RIP unit 111 converts the image data in a vector format into recording data in raster format and writes the recording data for a plurality of pages into the second RAM 102 as data of one page (S9).
If it is determined that the available capacity of the second RAM 102 is not equal to or larger than the predetermined amount X (S8: NO), the RIP unit 111, based on the image data included in the recording command, generates a plurality of recording data each corresponding to each of the plurality of images (generation processing), and sequentially writes the plurality of generated recording data into the second RAM 102 (output processing). At this time, the RIP unit 111 converts the image data in a vector format into recording data in a raster format and sequentially writes the recording data for each page into the second RAM 102 (S10).
After S5, the RIP unit 111 converts the image data in a vector format into recording data in a raster format, and writes the recording data for each page into the second RAM 102 (S11), similarly to S10.
After S9, S10 or S11, the RIP unit 111 transmits, to the image processing unit 112, an instruction signal instructing execution of recording processing (S12, S13 or S14). The instruction signal of S12 includes a notification indicating that data combining is not required. The instruction signal of S13 includes a notification indicating that data combining is required. After S12, S13 or S14, the RIP unit 111 ends the routine.
Next, processing that is executed by the image processing unit 112 will be described with reference to
The image processing unit 112 first determines whether the instruction signal has been received from the RIP unit 111 (S21).
If it is determined that the instruction signal has not been received from the RIP unit 111 (S21: NO), the image processing unit 112 repeats the processing of S21.
If it is determined that the instruction signal has been received from the RIP unit 111 (S21: YES), the image processing unit 112 reads out data (selection data, recording data, etc.) from the second RAM 102 (S22).
After S22, the image processing unit 112 determines whether the selection data read out in S22 indicates selection of the roll sheet Pr (S23).
If it is determined that the selection data does not indicate selection of the roll sheet Pr (i.e., indicates selection of the cut sheet Pc) (S23: NO), the image processing unit 112 converts the recording data read out from the second RAM 102 (density data of each color of RGB output from the RIP unit 111) into ejection data (data indicating an ejection amount in each ejection period for each nozzle), and controls the conveying motor 30 and the driver IC 50 based on the ejection data. Thereby, the conveyance mechanism 3 is caused to convey the cut sheet Pc from the sheet feeding tray 20 along the conveyance path T2 (refer to
If it is determined that the selection data indicates selection of the roll sheet Pr (S23: YES), it is determined whether the notification included in the instruction signal is a notification indicating that data combining is required (S25).
If it is determined that the notification included in the instruction signal is not a notification indicating that data combining is required (i.e., is a notification indicating that data combining is not required) (S25: NO), the image processing unit 112 converts the recording data read out from the second RAM 102 into ejection data (without performing data combining to be described later), and controls the conveying motor 30, the driver IC 50, and the cutting motor 40 based on the ejection data. In this way, the combination-recording is performed on the roll sheet Pr (S26: combination-record processing).
If it is determined that the notification included in the instruction signal is a notification indicating that data combining is required (S25: YES), the image processing unit 112 performs data combining described later on the recording data sequentially read out from the second RAM 102, converts the data into ejection data, and controls the conveying motor 30, the driver IC 50, and the cutting motor 40. In this way, the combination-recording is performed on the roll sheet Pr (S27: combination-record processing).
In S26 and S27, the image processing unit 112 causes the conveyance mechanism 3 to convey the roll sheet Pr along the conveying path T1 from the sheet feeding tray 10 (refer to
Data combining refers to converting recording data for a plurality of pages into data of one page. Here, data combining will be described with reference to
As described above, according to the present embodiment, in the printer 1, if it is determined that the image data including a plurality of images is received (S2: YES) and the combination-recording is to be performed (S3: YES), the combination-record processing (S26, S27) of causing the conveyance mechanism 3 to convey the single roll sheet Pr and causing the head 5 to record the plurality of images aligned in the conveyance direction on the single roll sheet Pr is executed. This makes it possible to record an image having a long-length in the conveyance direction, regardless of the type of the printer driver installed in the PC 200 (refer to
The printer 1 makes the plurality of images I to be continuously recorded in the conveyance direction, in the combination-record processing (refer to
The printer 1 deletes the margins A between the plurality of images I respectively included in two adjacent pages P1 to P3 (refer to stages (b) and (c) in
The printer 1 includes the RIP unit 111 and the image processing unit 112 (refer to
The printer 1 includes the RIP unit 111 and the image processing unit 112 (refer to
If the available capacity of the second RAM 102 is not equal to or larger than the predetermined amount X (S8: NO), the RIP unit 111 sequentially writes the plurality of recording data into the second RAM 102 (S10), and the image processing unit 112 executes the recording processing on the recording data read out sequentially from the second RAM 102 (S27). On the other hand, if the available capacity of the second RAM 102 is equal to or larger than the predetermined amount X (S8: YES), the RIP unit 111 writes the recording data relating to the plurality of images I (refer to stage (d) in
If the number of images included in the image data is larger than the number of images input to the interface 150 (S6: YES), the RIP unit 111 executes the notification processing of notifying that the number of images included in the image data is larger than the number of images input to the interface 150 (S7). In this case, the user can recognize that the number of images included in the image data is larger than the number input to the interface 150, and can respond appropriately. In this way, it is possible to suppress the inability to implement the recording desired by the user.
In S7, the RIP unit 111 prompts the user to perform re-input to the interface 150 via the notification unit 160 (refer to
If the number of images included in the image data is equal to or less than the number of images input to the interface 150 (S6: NO), the combination-record processing (S26, S27) is executed based on the image data received in the receiving processing. If the number of images included in the image data is equal to or less than the number input to the interface 150, it is easy to implement the recording desired by the user without performing the notification processing (S7).
If image data including one image is received (S2: NO), the image processing unit 112 causes the conveyance mechanism 3 to convey the cut sheet Pc accommodated in the sheet feeding tray 20 (S5→S23: NO→S24). In this case, waste of the roll sheet Pr can be suppressed.
If it is determined that image data including a plurality of images is received (S2: YES) and the combination-recording is not to be performed (S3: NO), the image processing unit 112 causes the conveyance mechanism 3 to sequentially convey the cut sheets Pc accommodated in the sheet feeding tray 20 (S5→S23: NO→S24). In this case, waste of the roll sheet Pr can be suppressed.
A printer (image recording apparatus) according to a second embodiment of the present disclosure is different from the first embodiment, in that the head 5 is of a laser type instead of an inkjet type.
In the first embodiment, the plurality of images I are continuously recorded in the conveyance direction (refer to stage (d) in
On the other hand, in the second embodiment, the plurality of images I are continuously recorded in the conveyance direction by shifting a position, in the conveyance direction, of one or more images I among the plurality of images I in the corresponding pages P1 to P3 (refer to stage (d) in
In the configuration of the present embodiment, an output position of toner may be adjusted in the conveyance direction, and the configuration is preferable when the head 5 is of a laser type. Note that, when a large margin A is created at the downstream end of the third page P3 with respect to the conveyance direction due to the shifting of the position of the image I in the conveyance direction, the cutting position by the cutting mechanism 4 may be adjusted.
While the invention has been described in conjunction with various example structures outlined above and illustrated in the figures, various alternatives, modifications, variations, improvements, and/or substantial equivalents, whether known or that may be presently unforeseen, may become apparent to those having at least ordinary skill in the art. Accordingly, the example embodiments of the disclosure, as set forth above, are intended to be illustrative of the invention, and not limiting the invention. Various changes may be made without departing from the spirit and scope of the disclosure. Therefore, the disclosure is intended to embrace all known or later developed alternatives, modifications, variations, improvements, and/or substantial equivalents.
In the embodiments described above, the number of images to be combined in the combination-recording is determined based on the user input. However, the present invention is not limited thereto. For example, the controller may determine the number of images to be combined by calculation or the like, based on image data received from an external apparatus.
An upper limit may be provided with respect to the number of images to be combined (for example, a value obtained by dividing a length of the roll sheet Pr in the conveyance direction by a length of the A4 size in the conveyance direction may be set as the upper limit), and an error notification may be performed when the upper limit is exceeded.
If the number of images included in the image data is larger than the number of images input to the interface 150 (S6: YES), the notification processing (S7) may not be performed, and the combination-record processing may be forcibly executed based on the number of images input to the interface 150.
Alternatively, if the number M of images included in the image data is larger than the number N of images input to the interface 150 (S6: YES), instead of the prompting for re-input in S7, a notification such as “Do you want to perform combining for M pages?” may be performed, and if YES, the combination-record processing for M pages may be executed, and if NO, the recording processing may be executed in a unit of one page without combining (M-N) pages.
In the embodiments described above, in the combination-record processing, the plurality of images I are continuously recorded in the conveyance direction (i.e., with no margin A in between), but may be recorded with the margin A in between without being limited thereto.
The sheet-shaped medium is not limited to paper, but may also be cloth or plastic film. That is, the sheet-shaped medium may be made of any material as long as it has a sheet shape.
The recorder may also eject liquid other than the ink (for example, treatment liquid that aggregates or precipitates components in the ink) when it is of a liquid discharge type. Also, the recorder is not limited to a liquid discharge type or a laser type, and may also be of a thermal transfer type or the like.
The present invention is not limited to the printer, and can also be applied to a facsimile, a copier, a complex machine, and the like.
The program according to the present disclosure can be distributed with being recorded on a removable recording medium such as a flexible disk or a fixed recording medium such as a hard disk, as well as can be distributed via a communication line.
