Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a copying machine, a printer,
The present invention relates to an image recording device such as a fax machine, and more particularly to an image recording device that performs a process of inserting a slip sheet between sheets after image recording.

[0002]

2. Description of the Related Art For example, when a manuscript is copied and bound in a copying machine, a blank or colored paper called interleaving paper is provided between recording papers on which the manuscript is copied so that chapter divisions can be easily identified. Is being inserted.

For example, Japanese Unexamined Patent Publication No. 2-11077 discloses an interleaving paper processing device which inserts interleaving paper between OHP sheets at a predetermined number when copying a double-sided original or a single-sided original onto an OHP sheet. ing. However, in the slip sheet processing apparatus described in the publication, the target for inserting the slip sheet is O.
Since it is an HP sheet, how to insert the interleaving paper when images are formed on both sides of the recording paper is not shown.

[0004]

Some copying machines are capable of double-sided copying and insert interleaving paper.
In such a copying machine, a recording paper for double-sided recording may be created from a single-sided original or a double-sided original, and a slip sheet may be inserted into a predetermined page of the double-sided recording paper. For example, when copying and binding an original, it is necessary to insert a slip sheet between the recording sheets on which the original is copied so that chapter divisions can be easily identified. In such a case, the slip sheet processing apparatus described in the above publication could not handle it.

Therefore, the present invention is characterized in that when a double-sided recording sheet is prepared from a single-sided original, a double-sided original, or an electronic original, a slip sheet can be inserted into an arbitrary page. And

[0006]

In order to achieve the above-mentioned object, the image recording apparatus of the present invention is capable of recording images on both sides of a recording sheet, and inserts a slip sheet between the recording sheets on which the image is recorded. In the image recording apparatus, a means for determining whether the page in which the slip sheet should be inserted is after single-sided recording or after double-sided recording, and when the single-sided recording is performed according to the determination result of this determination means, the sheet after the single-sided recording is discharged It is characterized by having a control means for feeding the interleaf sheet later and feeding the interleaf sheet as it is after double-sided recording.

[0007]

If the page into which the slip sheet is to be inserted has been printed on one side, the image of the next page cannot be printed on the opposite side of the one side, so the slip sheet is fed after discharging the printed sheet. If a page is to be inserted and the page in which the slip sheet is to be inserted is after double-sided recording, the page is separated from the image of the next page, so the slip sheet is fed as it is. Thereby, the slip sheet can be inserted into any page.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The features of the present invention will be specifically described below based on embodiments with reference to the drawings.

FIG. 1 is a schematic diagram showing a schematic configuration of a copying machine to which the image recording apparatus of the present invention is applied.

In the copying machine shown in FIG. 1, a platen glass 2 for placing an original is arranged on the upper surface of a copying machine main body 1, and an image recording system 5 having an image reading system 3 and a belt photosensitive member 4 below the platen glass 2. Each device is arranged. In addition, the copier 1 has
An upper paper feed tray 6-1, a middle paper feed tray 6-2, and a lower paper feed tray 6-3 are attached. An inverter 8 and a double-sided tray 9 are arranged in a paper transport system 7 for transporting the recording paper in each paper feed tray. Further, a user interface 10 including a display, operation keys and the like is attached to the upper part of the copying machine 1, and an automatic double-sided document feeder 11 is attached to the platen glass 2.

The originals to be copied are fed one by one to a predetermined position on the platen glass 2 by the automatic double-sided original feeding device 11, and the images of the originals are formed by the image reading system 3 which moves along the lower surface of the platen glass 2. To be scanned. The reflected light from the original is once converted into an image signal by the image sensor in the image reading system 3, subjected to predetermined image processing, and then supplied to the raster output scanner, and the laser beam from the raster output scanner is used as a photoconductor. 4 is illuminated.

The image recording system 5 records an image by, for example, an electrophotographic system, and as is well known, a charging device, an exposure device, a developing device, a transfer device, and a cleaning device are provided around the photosensitive member 4. Etc. (none of which are shown) are sequentially arranged.

The surface of the photoconductor 4 is uniformly charged by a charging device and exposed to light corresponding to the image of the original, and an electrostatic latent image corresponding to the image of the original is formed on the surface of the photoconductor 4. . This electrostatic latent image is developed with toner in a developing device to generate a toner image. In synchronism with the generation of the toner image, the recording paper is conveyed from the paper feed trays 6-1, 6-2, 6-3 or the double-sided tray 9 through the path A in the direction of the transfer portion T of the photoconductor 4 and is exposed. The toner image on the body 4 is transferred to the transfer device.
A toner image corresponding to the original image is recorded on the recording paper by (not shown). The toner remaining on the photoconductor after the transfer is removed by a cleaning device (not shown) to prepare for the next image forming cycle.

The recording paper after the one-sided recording passes through the fixing path 12 through the path B, and the toner image is fixed on the recording paper.
The recording paper after fixing is discharged to the outside of the apparatus through the path C in the case of single-sided recording. In the case of double-sided recording, the recording paper after fixing is sent to the inverter 8 through the path D and the front and back sides thereof are reversed, and then sent to the double-sided tray 9 through the path E.

The recording paper in the double-sided tray 9 is the paper feed tray 6.
Similar to the recording paper from -1, 6-2, 6-3, but with the front and back reversed, the image is transferred to the transfer section T of the photoconductor 4 and the image on the back side of the document is transferred to the back side. The double-sided recording paper after transfer again passes through the fixing device 12 through the path B, the toner image on the back side is fixed, and this time it is discharged to the outside of the apparatus.

In a normal copying operation, the paper feed tray 6
Sheets of different sizes are stored in -1, 6-2, and 6-3. When inserting a slip sheet, which will be described later, for example, the sheet feed trays 6-1 and 6-2 are replaced by the slip sheet trays. These paper feed trays 6-1 and 6-2 store sheets of different colors that are interleaf sheets, and the paper feed tray 6-3 stores recording sheets on which original images are recorded. To do.

FIG. 2 is a schematic block diagram showing an electric circuit in the copying machine shown in FIG.

The control unit 21 includes a user interface unit 2
2 (corresponding to the user interface 10 in FIG. 1), an automatic double-sided document feeding unit 23 (corresponding to the automatic double-sided document feeding unit 11), an image reading unit 24 (corresponding to the image reading system 3), image processing The operation of the device 25 and the image forming unit 26 (corresponding to the image recording system 5) is controlled. In addition, the image processing device 25
A mass storage device 27 is connected to. The control unit 21 is controlled by, for example, a microcomputer, and as is well known, a CPU (central processing unit), a RAM (random access memory), a ROM.
(Read-only memory) and the like.

The image signal from the document reading section 24 is supplied to the image processing section 25 and subjected to predetermined image processing and then to the image forming section 26 to obtain an image corresponding to the document image on the recording paper. The image data of the original read by the image reading unit 24 is stored in the mass storage device 27 as needed.

FIG. 3 is a front view showing the user interface 10. Front part 31 of the user interface 10
A CRT display 32 is arranged as a display device, and various operation keys such as a ten key 33, a start key 34, and a function selection key 35 are arranged.

FIG. 4 shows an example of a slip sheet insertion window displayed on the CRT display 32 when the slip sheet insertion mode is selected on the user interface 10. A transparent touch screen is provided on the front surface of the CRT display 32, and by touching a predetermined portion of the display surface of the CRT display 32 with a finger, information corresponding to the touched position can be input. The page display unit 41 displays the page number in which the slip sheet is inserted, and the ten key 3 of the user interface shown in FIG.
If you press the setting key 42 after entering the page number in 3,
The entered page number is stored in the control unit 21 R
The page number is stored in the predetermined area of AM, and this page number is displayed in the first frame of the insertion page number display portion 43. In the same manner, the page number input and setting operations are repeated. The example of FIG. 4 shows a state in which pages 3, 5, 10, and 15 are set as insertion pages. Further, when the after-page key 44 is pressed, a slip sheet is inserted after each page. The interleaving paper tray selection keys 45a and 45b are used to select a color of interleaving paper to be inserted, and trays 1 and 2 (for example, the paper feeding trays 6-1 and 6) in which interleaving papers having different colors are stored. (Corresponding to -2), it is possible to select a slip sheet of a desired color. Further, the interleaf paper tray selection key 45c is
This is for selecting a sheet from a tray (for example, the sheet feeding tray 6-3) that stores copy sheets as the slip sheet.

It should be noted that the same page can be designated multiple times as the insertion page. This is effective when inserting a plurality of blank sheets as memo paper after the designated page. If a page that does not exist is specified,
A message to that effect is displayed and the slip sheet processing is not performed.

Next, a slip sheet inserting process in the above copying machine will be described. Now, let us consider a case where a double-sided copy is made from the single-sided originals D1 to D6 as shown in FIG. In this case, (1) reading of the first document D1 → first recording sheet P
Recording on the front side of (1) (2) Reading the second document D2 → the first recording sheet P
Recording on the reverse side of 1 (3) Ejection of the first recording paper P1 (4) Reading of the third original D3 → Second recording paper P
Recording on the front side of (2) Reading the fourth document D4 → Second recording paper P
Recording on the reverse side of (2) (6) Ejecting the second recording paper P2 (7) Reading the fifth original D5 → third recording paper P
Recording on the front side of (3) (8) Reading the sixth document D6 → The third recording sheet P
Recording on the reverse side of (3) (3) Ejecting the third recording sheet P3 In this way, reading the original, recording the image, and ejecting the recording sheet are sequentially performed, and three sides of the sheet as shown in FIG. Copies P1 to P3 are obtained.

Also, a double-sided document D as shown in FIG.
When making a double-sided copy from 1 to D3, (1) front side reading of the first original D1 → recording on the front side of the first recording paper P1 (2) back side reading of the first original D1 → first Recording on the back side of the recording paper P1 (3) Ejecting the first recording paper P1 (4) Reading the front side of the second document D2 → Recording on the front side of the second recording paper P2 (5) Recording the second document D2 Back side reading → Recording on the back side of the second recording sheet P2 (6) Ejecting the second recording sheet P2 (7) Front side reading of the third document D3 → Recording on the front side of the third recording sheet P3 (8) Reading the back side of the third document D3 → Recording on the back side of the third recording sheet P3 (9) By the process of ejecting the third recording sheet P3, as in the case of the above single-sided original, as shown in FIG.
Three double-sided copies P1 to P3 as shown in (a) are obtained.

Next, let us consider a case of making a double-sided copy while inserting a slip sheet from a single-sided original as shown in FIG. Note that, here, it is assumed that the slip sheet is inserted after one page and after three pages of the document. In this case, (1) reading of the first document D1 → first recording sheet P
Recording on the front surface of 1 (2) Ejection of first recording paper P1 (3) Emission of first interleaving paper S1 (4) Reading of second document D2 → Second recording paper P
Recording on the front side of (2) Reading the third original D3 → second recording paper P
Recording on the reverse side of 2 (6) Second recording paper P2 discharge (7) Second interleaving paper S2 discharge (8) Fourth document D4 read → third recording paper P
Recording on the surface of No. 3 (9) Reading the fifth document D5 → The third recording paper P
Recording on the reverse side of 3 (10) Ejecting the third recording sheet P3 (11) Reading the sixth document D6 → Recording on the front side of the fourth recording sheet P4 (12) Ejecting the fourth recording sheet P4 Then, the original is read, the image is recorded, the recording paper is ejected, and the interleaf is inserted, and four interleaf sheets are inserted after one page and three pages as shown in FIG. 6B. You get a copy.

The same applies to the case of making a double-sided copy while inserting a slip sheet from a double-sided original, so the description thereof will be omitted. However, when inserting a slip sheet after an odd number of pages of the original as described above, it is originally necessary. Since continuous pages that should be printed on the front and back sides of one sheet of recording paper straddle one sheet of recording paper, whether an original is one-sided or two-sided when an image is formed on the recording sheet. Alternatively, the order in which the image is formed on the recording paper differs depending on various copying conditions such as the number of pages to insert the slip sheet.

Therefore, in this embodiment, an appropriate copy is obtained in any case by forming an image and discharging the recording paper in an appropriate order according to various copying conditions.

The processing under each condition will be described below.

FIG. 7 and FIG. 8 show a flowchart of the slip sheet process when making a double-sided copy from a single-sided original. The page number into which the slip sheet is to be inserted is assumed to be input in advance from the user interface 10.

When the start key 34 of the user interface 10 is pressed (step 101), the slip-sheet insertion page number is transcribed on the RAM table (step 10).
2). Note that this table may use an area other than the area for storing the slip-sheet insertion page number input from the user interface 10 in the RAM area. Next, "1" indicating the first side is set in the variable CopySide indicating the copy side of the recording paper, and the original page number is set to "0".
Is set (step 103). Next, it is determined whether or not the original page number matches the slip sheet insertion page number stored in the table. If they match, the slip sheet is fed from the slip sheet tray (paper feed tray 6-1 or 6-2). To be discharged to the outside of the machine. The document page number can be known by counting the number of documents sent from the automatic double-sided document feeder 11 onto the platen glass 2 with a counter. Next, the slip-sheet insertion page number is deleted from the table on the RAM (step 106).

If the original page number does not match the slip-sheet insertion page in step 104, the automatic double-sided original feeder 11 sends one original onto the platen glass 2.
(Step 107), increment the original page number by 1.
(Step 108). Next, it is determined whether or not the original page number and the slip-sheet insertion page match (step 109), and if they do not match, the copy surface is determined (step 110).
When CopySide = 1, that is, when the first side is the first side, a single-sided copy is made and discharged to the double-sided tray 9 (step 111), and CopySide is set to "2".
If CopySide ≠ 1, ie, the second side, a double-sided copy is made and discharged outside the machine (step 114), and CopySide is set to "1" (step 115). Next, after the document on the platen glass 2 is discharged (step 113), it is determined whether or not there is a subsequent document, and if there is no subsequent document, the process ends. If there is a subsequent document, the process returns to step 107. The presence / absence of a subsequent document can be known by a document sensor provided in the automatic double-sided document feeder 11.

If the original page number and the slip-inserted page match in step 107, the copy side is determined (step 117), and if it is the first side, a single-sided copy is taken and ejected out of the machine ( If it is the second side in step 118), a two-sided copy is taken and discharged outside the machine (step 119), and CopySide is set to "1" (step 120). Next, the slip sheet is sent out from the slip sheet tray and discharged to the outside of the machine (step 121), and the slip sheet insertion page number is deleted from the table on the RAM (step 12).
2). Next, it is determined whether the original page number and the slip-inserted page match, and if they match, the process returns to step 121, and if they do not match, the process jumps to step 113.

FIG. 9 and FIG. 10 show a flowchart of the slip sheet process when making a double-sided copy from a double-sided original. The steps corresponding to those in FIGS. 7 and 8 are designated by the same reference numerals. This flowchart is similar to the flowcharts shown in FIGS. 7 and 8, but after step 107, the variable DocSid indicating the copy surface of the original document.
Set "1" for e to the first surface (step 20)
1) point and that processing is switched according to the value of the variable DocSide. That is, the surface of the original is determined (step 202), DocSide = 1,
That is, when it is the first side, the original on the platen glass 2 is inverted by the automatic double-sided document feeder 11 and is set again on the platen glass 2 (step 203).
After setting ocSide to "2" (step 20
4) The point that it returns to step 108 is different.

In the above embodiment, the automatic double-sided document feeder 11 was used to set the originals one by one on the platen glass 2 for copying, but the automatic double-sided document feeder 11 and the image reading system 3 were previously set. Image reading unit 2 provided in
4, the images of all the pages of the original are read and stored as image data in a large-capacity storage device 27 connected to the image processing device 25, and a predetermined amount is stored in the large-capacity storage device 27 at the time of image formation. It is also possible to read the image data of the page of the document and form the image on the recording paper by the image forming unit 26 in an arbitrary order based on the image data.

FIG. 11 and FIG. 12 show a flow chart for making a double-sided copy in the copying machine of the type in which the image data of the original is stored in the mass storage device 27 as described above. Steps corresponding to those in FIGS. 7 and 8 are designated by the same reference numerals. This flowchart is similar to the flowcharts shown in FIGS. 7 and 8, but after step 102, all the originals are read by the image reading unit 24, and page numbers are added to the image data of each page in the order of reading. Point (step 301), and one page of image data is read from the mass storage device 27.
(Step 302) is different.

In the above embodiment, the interleaf sheet insertion page is input from the user interface 10. However, a separator sheet indicating the page into which the interleaf sheet should be inserted is inserted between the originals for copying. At this time, it is possible to detect the presence or absence of this separator and insert a slip sheet at that position. It should be noted that the detection of the separator is made such that the separator has a size and a color different from those of the recording paper, as described in JP-A-1-177566 and JP-A-4-86759.
This can be performed by a paper sensor provided in the automatic double-sided document feeder 11.

FIG. 13 shows a flow chart in the case of setting the interleaf sheet insertion page by the separator sheet in this way. Steps corresponding to those in FIGS. 7 and 8 are designated by the same reference numerals. This flowchart is similar to the flowcharts shown in FIGS. 7 and 8, but instead of determining whether the document page number and the slip-sheet insertion page match, determining whether the document is a separator sheet ( Step 401),
Also, a separator is detected, and when the copy surface of the recording paper is the second surface at this time, the single-sided copy in the double-sided tray 9 is ejected to the outside of the machine (Step 402), and CopySid is set.
Point e is set to "1" (step 403), and the slip sheet is sent out from the slip sheet tray and discharged to the outside of the machine (step 40).
4) is different.

As described above, when setting the interleaf sheet insertion page by the separator, it is not necessary for the user to count the pages into which the interleaf sheet is to be inserted and input them into the user interface 10. Therefore, the operation for inserting the interleaf sheet is performed. Has the advantage of being very simple.
