Description

  The present invention relates to a composite image forming apparatus (hereinafter, also referred to as “hybrid printing apparatus”) having a plurality of printing units with different printing methods, and more specifically, a plurality of reduced-size or small-size printed images (plate making images). The present invention relates to a composite type image forming apparatus capable of multi-sided printing that collects and prints at once.

There is a desire to print a part of the entire printed image as a color image, or to print a different image (including a color image) for each part. In response, so-called hybrid printing devices have been developed and put into practical use. ing.
In the hybrid printing device, for example, if the address for postcards, envelopes, DM (direct mail) documents, etc. is different from one sheet to another, the plate is advantageous in terms of cost when the common image part (fixed image part) is mass-printed. The printing is performed by printing (for example, stencil printing), and a variable image portion such as an address is performed by plateless printing (for example, ink jet printing) performed by only data control without using a plate.
As a hybrid printing apparatus, for example, those described in JP-A-2002-137514, JP-A-2002-137515, and JP-A-2002-225410 are known.

In the printing apparatus, for example, as disclosed in Japanese Patent Publication No. 2-21940 and Japanese Patent Application Laid-Open No. 2001-347739, two originals of different sizes can be collectively printed, or one type or So-called aggregate printing is performed in which two types of originals are arranged and printed on two or four sides. Centralized printing has the advantage that the master usage can be reduced and the printing time can be shortened.
Specifically, in the two-side consolidated printing, as shown in FIG. 14, for example, a document having a different A4 size, that is, a document 100 holding an image “A” and a document 101 holding an image “B” are read. The plate-making images are arranged in the paper conveyance direction, are made as A3 size as the general-purpose maximum size of the stencil printing apparatus, and are cut after printing.
In the four-side consolidated printing, as shown in FIG. 15, one type of A4-size original 103 is reduced to 50%, for example, and image data is arranged in two rows in one plate (A3 size) and in the same direction in the paper transport direction. The top four are made side by side and cut after printing.

In the hybrid printing apparatus, the part to be printed by the inkjet printing unit is positioned as a partial and variable part such as an address as described above, and therefore, the characteristics of the hybrid printing apparatus can be exhibited.
In this way, in the hybrid printing apparatus that performs printing on a part of the entire image in the inkjet printing unit, it is advantageous in terms of cost that the width of the inkjet recording head (the length in the direction orthogonal to the paper conveyance direction) is narrow, In line with the development philosophy of hybrid printing equipment.

When performing numbering printing or the like on a printing paper, for example, as shown in FIG. If printing is performed for each sheet, the inkjet recording head 104 corresponds to the numbering printing unit 106 of the printing paper 105, so that inkjet printing is possible.
However, in printing such as four-sided continuous shooting, as shown in FIG. 17, for example, as shown in FIG. 17, the numbering printing portion of each print image is separated in the direction orthogonal to the paper transport direction, and thus when performing inkjet printing without reducing the printing speed. Can print only two sheets on one side because the width of the inkjet recording head 104 is narrow.
Only in order to solve this problem, if the width of the inkjet recording head 104 is adapted to the full width (line type full width fixing method), the cost increases.

The four-direction key 59 has an upper key 59a, a lower key 59b, a left key 59c, and a right key 59d, and is used for various settings. The image position adjustment key 60 is used when the movement mechanism 36 is operated to move the position of the ink jet print image with respect to the paper 2 or when the movement mechanism (not shown) is operated to move the position of the stencil print image with respect to the paper 2. Is pressed when both are performed. The image switching key 61 is pressed when selecting an image whose position with respect to the paper 2 is moved, and the image moved each time the button is pressed is switched between a stencil printing image and an inkjet printing image. In the vicinity of the image switching key 61, LEDs 61a and 61b indicating images to be moved are arranged.

The interlocking movement key 62 is pressed when selecting both the stencil printing image and the ink jet printing image as images for moving the position with respect to the paper 2 and moving them in the same direction by the same movement amount. The ink jet composition key 63 is pressed when an ink jet print image is formed on the paper 2 on which the stencil print image is formed.
In the vicinity of the ink jet composition key 63, LEDs 63a and 63b are disposed to indicate the case with composition and the case without composition. When there is no ink jet composition, the paper 2 is transferred from the paper transport roller pair 27 to the paper transport roller pair 29 with the ink jet recording head 26 being inoperative.

  FIG. 5 is a control block diagram of the composite image forming apparatus 1. The composite image forming apparatus 1 includes an image processing device 37 as a control unit. The common print image data read by the image reading unit 40 is temporarily stored in the common data storage memory 65 or directly subjected to predetermined image processing by the common image (fixed image) data processing device 38, and then the image forming unit. It is sent to the thermal head drive control device 44 via the selection means 39, and based on this data, each heating element of the thermal head 15 selectively generates heat to perform perforating plate making for the master 13.

  On the other hand, the variable image data sent from the personal computer 45 is subjected to predetermined image processing by the variable image data processing device 46 and then sent to the inkjet head drive control device 47 via the image forming unit selection means 39. Based on this data, the ink jet recording head 26 selectively ejects ink to form an image. Alternatively, the variable image data sent from the variable data storage memory 48 in which necessary image data is recorded in advance is sent to the inkjet head drive control device 47 via the image forming unit selection means 39, and based on this data The ink jet recording head 26 selectively ejects ink to form an image. The position of the inkjet recording head 26 with respect to the conveyed paper 2 is controlled by a recording head positioning drive control device 49.

Based on the above-described configuration, an operation for forming a stencil print image and an inkjet print image on the paper 2 using the composite image forming apparatus 1 will be described below. The operator presses the ink jet composition key 63 on the operation panel 50 to light the LED 63a, sets the document 42 in the image reading unit 40, and presses the plate making start key 51.
When the plate making start key 51 is pressed, the scanning unit 41 scans the image of the document 42 and sends this data to the image sensor 43, and a plate discharging device (not shown) is activated to be used from the outer peripheral surface of the plate cylinder 20. The master-making master 19 is peeled off. After completion of the plate removal operation, the plate cylinder 20 rotates to a predetermined plate supply standby position and stops, and a clamper (not shown) provided on the outer peripheral surface is opened to enter a plate supply standby state.
When the plate cylinder 20 enters a plate feed standby state, the platen roller 16 and the master transport roller pair 18 are operated to send out the master 13. The sent master 13 is punched and made based on the image data sent to the image sensor 43 when passing through the thermal head 15. The master 13, which has been subjected to plate making and becomes a plate-made master 19, is clamped by a clamper of the plate cylinder 20, and then the plate cylinder 20 is driven to rotate at the same peripheral speed as the conveying speed of the master 13. It is wound on the outer peripheral surface. When the master 13 for one plate is conveyed, the cutting means 17 is operated to cut the master 13 and the winding operation is completed.

After the winding operation is completed, when the test printing key 53 is pressed by the operator, the paper feed roller 11 is operated to feed one sheet 2 from the paper feed tray 10. The fed paper 2 is temporarily stopped by the registration roller pair 12 and then fed between the plate cylinder 20 and the press roller 22 at a predetermined timing.
After the operation of the registration roller pair 12, the press roller 22 presses the peripheral surface thereof against the master 19 that has been wound on the outer peripheral surface of the plate cylinder 20, whereby the stencil image is transferred onto the paper 2. The sheet 2 to which the stencil printing image has been transferred is peeled off from the master 19 on the plate cylinder 20 by the peeling claw 23, sent to the belt transport unit 25, and further transported downstream.
The paper 2 sent by the belt transport unit 25 is further transported by a pair of paper transport rollers 27, and when the leading end is detected by a paper detection sensor 32, data is sent from a personal computer (not shown) or a data recording device (not shown). . Then, the ink jet recording head 26 operates based on the sent data, and an ink jet print image is formed on the paper 2.
The paper 2 on which the stencil printing image and the ink jet printing image are formed is fed by the paper conveyance roller pair 29 and is discharged to the paper discharge tray 35 via the belt conveyance unit 34.

FIG. 6 shows the sheet 2 on which an image is formed by the above-described test printing. On the paper 2, a stencil print image 28 and an ink jet print image 30 are formed. A case where the test-printed paper 2 is confirmed and the positions of the images 28 and 30 are moved will be described below.
In FIG. 6, the stencil print image 28 can move in the paper conveyance direction indicated by arrow A and the paper width direction indicated by arrow B, and the inkjet print image 30 can be moved in the paper conveyance direction indicated by arrow AA and the paper width direction indicated by arrow BB. Can be moved to. The operator presses the image position adjustment key 60 on the operation panel 50 before moving the images 28 and 30. When the image position adjustment key 60 is pressed, the display on the display device 58 is in the state shown in FIG.
Next, the operator selects whether the image whose position is to be adjusted is the stencil print image 28 or the inkjet print image 30. Selection is performed by pressing the image switching key 61. Each time the image switching key 61 is pressed, the image whose position is adjusted is switched to the stencil printing image 28 or the ink jet printing image 30, and the corresponding LEDs 61a and 61b are turned on. When the image to be adjusted is selected, the movement amount of the image is input in the direction in which the user wants to move next by pressing the four-way key 59.

As shown in FIG. 3, the display device 58 displays the movement amount of the stencil printing image 28 and the movement amount of the inkjet printing image 30 adjacent to each other, and further the movement amount in the paper transport direction and the movement amount in the paper width direction. Are displayed adjacent to each other. The operator adjusts the positions of the images 28 and 30 while viewing this display.
For example, when the stencil print image 28 is moved 2.5 mm downstream in the paper conveyance direction, the image switch key 61 is pressed to turn on the LED 61a, and then the left key 59c is pressed. In this example, each time the four-way key 59 is pressed, the image moving amount is incremented by 0.5 mm. Therefore, to move 2.5 mm, the left key 59c is pressed five times. Then, the display 58a of the display device 58 becomes “+2.5”, and the instruction is completed. In this example, the stencil print image 28 is not moved in the paper width direction, and the display 58d of the display device 58 remains “0”.
Next, when the inkjet print image 30 is moved 2.0 mm downstream in the paper conveyance direction, the image switch key 61 is pressed to turn on the LED 61b, and then the left key 59c is pressed four times to display the display device 58. “+2.0” is displayed on the display 58b. Further, when the inkjet print image 30 is moved 1.5 mm toward the front side in the paper width direction, the down key 59b is pressed three times to display “−1.5” on the display 58c of the display device 58.

Hereinafter, the case of multi-sided printing (collective printing) will be described.
First, the four-plane continuous shooting will be described with reference to FIGS. When printing is not performed by the inkjet printing unit 5, the image processing device 37 as a control unit reads 50% of the read data of the A4 size document read by the image reading device 40 and stored in the common data storage memory 65. Then, as shown in FIG. 7, the plate-making images are edited by arranging them in two rows in the A3-size plate so as to be in the same direction in the paper transport direction. The data is transmitted to the thermal head drive control device 44, plate making is performed, and printing is performed.
As a result, stencil printing images 80a, 80b, 80c, and 80d of A4 size reduced by 50% are formed on the A3 size paper 2. These print images are cut after printing.

When numbering printing is performed by the inkjet printing unit 5 on the upper right part of each stencil printing image 80a, 80b, 80c, 80d, the image processing device 37 is read by the image reading device 40 and stored in the common data storage memory 65. The read data of the A4-size original is reduced to 50%, and the plate-making image is edited in two rows in the A3-size plate so as to be oriented in the paper transport direction as shown in FIG.
In this case, the image data corresponding to the stencil printing images 80a and 80b on the right side (upper side in the figure) divided into the right and left in the paper transport direction is rotated by 180 °, and the ink jet set in advance so as to be positioned at the center position of the paper Editing is performed so that all the numbering printing sections are within the width of the recording head 26 (within the printable area). The edited data is transmitted to the thermal head drive control device 44, plate making is performed, and printing is performed.
FIG. 8 shows a state before the numbering printing unit is printed by the inkjet printing unit 5, and at this point, the numbering printing unit is actually blank, but the image (when printed for easy understanding) ( Number) is displayed (the same applies hereinafter).

As for the print image (here, the number) in the ink jet printing unit 5, the internal pattern characters of the stencil printing unit 4 are sent to the ink jet head drive control device 47 as a signal. Since the number images in the stencil printing images 80a and 80b are in the reverse direction, they are transmitted in reverse. The stencil printing images 80a and 80b are reversely processed by the stencil printing unit 4 to make a plate.
When the numbering printing unit is provided at the upper left, the image data corresponding to the stencil printing images 80c and 80d is rotated by 180 °.

The plate-making operation in the case of the above four-plane continuous shooting will be described in detail based on the flowchart of FIG. However, a case where an ADF (automatic document feeder) not shown in FIG. 1 is used will be described.
First, the multi-frame continuous shooting menu key 64 is pressed (S1). Next, the number of continuous shots is input using the numeric keypad 55 (S2), and ink jet print characters are set using the display device 58 that also serves as a touch panel switch (S3). Similarly, an inkjet printing position is set on the display device 58 (S4). In this case, for example, “upper left”, “upper right”, “lower left”, and “lower right” are displayed at the same time, and any one is selected.
Next, the plate making start key 51 is pressed (S5). When the plate making start key 51 is pressed, reading of a document set on an ADF (not shown) of the document reading device 40 is started, and the read data is stored in the common data storage memory 65 (S6).
The image processing device 37 checks whether or not the trailing edge of the document has been detected, that is, whether or not the reading of the document has been completed (S7), and if completed, stops the conveyance of the document (S8).
After the document conveyance is stopped, the image processing device 37 performs the above-described image editing by rotating a part of the image data stored in the common data storage memory 65 (S9). Next, the plate making process is started (S10), and it is checked whether writing of the plate making is completed (S11).

The second embodiment will be described with reference to FIGS. Since the apparatus configuration is the same as that of the first embodiment, a description thereof will be omitted.
As shown in FIG. 10, the A4 size first document 81 and second document 82 are two-sided continuous shooting. A name is printed on the first original 81 at the lower right by the inkjet printing unit 5, and a name is printed on the second original 82 at the upper left by the inkjet printing unit 5.
In this case, even if the two-surface continuous shooting is performed as it is, the position of the name is separated in the direction orthogonal to the paper transport direction as shown in FIG. 10, so that only one of the narrow ink jet recording heads 26 can print.
In order to solve this problem, in the present embodiment, first, the first document 81 is read and plate-making is performed, and then the position of the name printed by the inkjet printing unit 5 of the second document 82 is the name of the first document 81. If it is different, the image written on the second original 82 is rotated by 180 ° as shown in FIG. 11, and the printable area (inkjet recording head 26 in the inkjet printing unit 5) is rotated. Move the name part to (printable area).

The plate making operation in this embodiment will be described in detail based on the flowchart of FIG.
First, the multi-frame continuous shooting menu key 64 is pressed (S1). Next, the number of documents is input using the numeric keypad 55 (S2), and ink jet print characters are set using the display device 58 (S3). Similarly, an inkjet printing position is set on the display device 58 (S4).
Next, the plate making start key 51 is pressed (S5). When the plate making start key 51 is pressed, reading of the first document set in the ADF (not shown) of the document reading device 40 is started and writing to the master 13 is performed (S6).
The image processing device 37 checks whether or not the trailing edge of the first document has been detected, that is, whether or not the reading of the first document has been completed (S7). In step S8, the conveyance of the first document is stopped (S9).

Next, on the display device 58, a question is displayed to the operator as to whether or not to change the ink jet printing setting for the second document (S10). Inkjet printing characters are set on the display device 58 (S11), and an inkjet printing position is set (S12).
Next, a question is displayed on the display device 58 as to whether or not the printing position in the inkjet printing unit 5 is the same in the left-right direction (the direction orthogonal to the paper transport direction) (S13). If the printing positions are different, the plate making start key 51 is pressed (S14). When the plate making start key 51 is pressed, reading of the second original is started, and the read data is stored in the common data storage memory 65 (S15).

The image processing device 37 checks whether or not the trailing edge of the second document has been detected, that is, whether or not the reading of the second document has ended (S16). (S17).
Next, the image processing device 37 rotates the memory image of the second document by 180 ° and performs image editing (S18). Next, the plate making process is started (S19), and it is checked whether or not the writing of the plate making is completed (S20).
If the inkjet printing setting is not changed in S10, or if the printing position in the inkjet printing unit 5 is the same in the left-right direction in S13, the plate making start key 51 is pressed (S21). When the plate making start key 51 is pressed, reading of the second original is started and writing to the master 13 is performed (S22).
The image processing device 37 checks whether or not the trailing edge of the second document has been detected, that is, whether or not the reading of the second document has been completed (S23). (S24), the conveyance of the second document is stopped (S25).

In the case of image reduction or two-sided continuous shooting with small images, for example, as shown in FIG. 13, the read data of an A4 size document is reduced to 50%, and the image data of two plate-making images are orthogonal to the paper transport direction. Image editing arranged in the direction may be performed, and half of the A3 size plate in the paper conveyance direction may be made non-plate-making (third embodiment).
In this way, the paper to be fed can be A4 size, and the printing cost can be reduced.

In the above-described embodiment, an example in which an image read from a document is rotated has been described. However, the same can be applied to image information sent from a personal computer.
Moreover, although the inkjet printing part was illustrated as a plateless printing part, the thing of a thermal transfer system or a laser printer system can also be employ | adopted.
The composite image forming apparatus 1 may be configured as one system in which an inkjet printing unit (inkjet printing device) 5 is attached to a stencil printing unit (stencil printing device) 4 and electrically connected in an electrical signal manner. The unit 4 and the inkjet printing unit 5 may be integrally provided in one housing.
