DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram illustrating a configuration example of a copying apparatus (image forming apparatus) according to the present embodiment. In FIG. 1, the copying apparatus includes an image reading unit 1.
0, image writing section 20, image forming section 30, transfer paper transport section 4
0, a transfer sheet discharge section 50 and a transfer sheet reversing section 60. The “transfer paper” in the present embodiment corresponds to the “recording material” in the present invention.

The image reading section 10 is a section for reading a character string or a picture described in a document as optical information by irradiating light from a light source, and converting this into electrical information (image data).

The original is placed directly on the platen glass 11 such that the original surface (the surface on which the image is formed) faces the surface of the platen glass (original glass) 11. The light source 12 projects light onto the surface of the placed document. The light that reaches the document surface becomes light (information) including the image information, is reflected by the surface, and reaches the mirror 13. The light source 12 and the mirror 13 are configured to be movable along the surface of the platen glass 11 so as to scan the entire document surface.

Further, the copying apparatus according to the present embodiment includes an automatic double-sided document transport section (RAD) as an automatic document feeding means.
F) 100 is provided. Automatic duplex document feeder 100
As shown in FIG. 1, a plurality of documents stacked on a document table 101 are separated from one another and sent out by feeding rollers 100a and 100b.
00c on the platen glass 11A. A fixed light source 12A and a mirror 13A are provided under the platen glass 11A. With these configurations, similarly to the above, with respect to a bundle of a plurality of documents, the document surfaces can be read continuously.

In addition to the above, in the configuration of the automatic double-sided document feeder 100 and the platen glass 11A shown in FIG.
It is also possible to read both sides of a document. In this case, one surface is read by the light source 12A, and when the reading is completed, the original is once sent rightward in FIG.
02 is reversed and the original is conveyed leftward in the figure while being wound up by the roller 100c so that the other side of the original faces the platen glass 11A. It should be noted that the light source 12
Documents read by A are sequentially stacked on the paper discharge tray 103.

Now, as described above, the light source 12 or 12A
Optical information relating to document surface read by the following, the mirror 14 _1, 14 ₂ or 15 _1, 15 ₂ repeatedly reflected and reaches the CCD image pickup device 17 through the imaging optical system 16. The CCD imaging device 17 has a photoelectric surface (not shown) on which a plurality of pixels having a photoelectric conversion function are arranged.
Optical information including image information of the document surface is received by the plurality of pixels, and is converted into electrical information.

The image writing section 20 irradiates (writes) a laser beam controlled on the basis of the electric information obtained as described above onto a photosensitive drum 31 described later, and irradiates the laser beam onto the photosensitive drum 31. This is a part where an electrostatic latent image is formed.

The electrical information including the image information obtained by converting the optical information relating to the original surface is used for controlling the laser beam oscillated from a semiconductor laser (not shown). The laser beam controlled and oscillated based on the electric information is applied to a rotatable polygon mirror 22 whose center is connected to a drive motor 21, and the laser beam reflected therefrom is reflected via a reflection mirror 23. And is irradiated onto the photosensitive drum 31. Here, as the polygon mirror 22 rotates while reflecting the laser beam, the laser beam is irradiated on the photosensitive drum 31 while being scanned in the axial direction. The irradiation of the laser beam causes the photosensitive drum 3
1, an electrostatic latent image based on the electrical information is formed.

The image forming unit 30 includes the photosensitive drum 31
This portion forms an image on the transfer paper P based on the electrostatic latent image formed thereon.

As described above, an electrostatic latent image is formed on the photosensitive drum 31 by the irradiation of the laser beam. As a prerequisite work, the entire surface of the photosensitive drum 31 is uniformly charged by the charging unit 32. Keep it. The developing unit 33 makes charged toner adhere to the electrostatic latent image to visualize the toner. In the transfer unit 34, the toner is transferred and adhered to a separately fed transfer paper P surface, and a toner image is formed on the transfer paper P surface.

Thereafter, on the photosensitive drum 31, the separating unit 35 separates the transfer paper P adsorbed on the photosensitive drum 31, and the cleaning unit 36 remains on the photosensitive drum 31 after the transfer operation. The toner is cleaned to reveal a clean surface, so that uniform charging by the charging unit 32 and formation of an electrostatic latent image by laser beam irradiation can be performed again. On the other hand, the transfer paper P is sent to the fixing unit 38 via the transport mechanism 37. The fixing unit 38 applies heat and pressure to the transfer paper P by the heat rollers 38a and 38b to fix the transferred toner image to form an image. Thereafter, the transfer paper P is discharged to the outside of the copying apparatus via a plurality of rollers provided in the transfer paper discharge unit 50. At this point, the “copy” of the image on the original surface onto the transfer paper P surface
Will be completed. Note that the discharge can be performed with the transfer paper P turned upside down.

In the copying apparatus according to the present embodiment, the transfer of the toner image from the photosensitive drum 31 to the transfer paper P is performed not only on one surface of the transfer paper P but on the other surface. Can also be implemented. In this case, the transfer paper P after the one-sided copying has been completed.
Is transported to the transfer paper reversing unit 60. The guide section 61
The transfer path of the transfer sheet P between the transfer sheet reversing section 60 and the transfer sheet discharge section 50 is switched. When the guide unit 61 is switched to convey the transfer sheet P downward in the drawing, the transfer sheet P is carried out to the reversing unit 63 via the reversing roller 62. Next, in a state where the transfer paper P is sent out to the reversing unit 63 by a predetermined amount, the reversing roller 62 is reversed, and the transfer paper P is transported to the reversal transport path 64. Hereinafter, transfer paper P
Passes through the path 64 and reaches the upstream side of the photosensitive drum 31 again. At this time, the surface of the transfer paper P facing the surface of the photosensitive drum 31 is different from the surface transferred before passing through the transfer paper reversing unit 60. In general, when an image is actually formed on the inverted transfer paper P, new image information is written on the photosensitive drum 31 by the image writing unit 20.

The transfer paper transport section 40 is a section for transporting the transfer paper P to the above-described image forming section 30, especially to the photosensitive drum 31 thereof.

The transfer paper P is stored in a plurality of paper feed cassettes (recording material storing means) 41 (steps 41 ₁ , 41 in FIG.
The stacks are stacked and placed on a tray 42 provided in each of three paper feed cassettes 41 ₂ and 41 ₃ . These paper feed cassettes 41 can be accommodated in the apparatus main body when sending the transfer paper P to the image forming section 30, that is, when forming an image, and can be pulled out from the apparatus main body when refilling the transfer paper P. It is configured as possible. Each of the sheet cassettes 41 ₁ , 41 ₂ and 41 ₃ has a size such as “A4” for the first sheet cassette 41 ₁ and “A3” for the second sheet cassette 41 ₂ . Different transfer paper P
And the first paper cassette 4
1 A4 size cardboard to _1, such as thin paper of the same size in the second sheet cassette 41 _2, so as to correspond to each other sheet type, it is possible to keep each housing.

In such a state, for example, if the size of the transfer paper P or the paper type is specified at the time of copying, the tray 42 in the corresponding paper feed cassette 41 is pushed upward in the figure according to the specification. As a result, the surface of the transfer paper P comes into contact with the peripheral surface of the delivery roller 43, and the transfer paper P is
It is paid out from. Thereafter, the transfer paper P is transferred to the image forming unit 30 by a configuration such as a plurality of transport rollers shown in FIG.
Will be conveyed toward.

Further, in the present embodiment, as shown in FIG. 1, a manual feed tray 41H is provided as a means for feeding the transfer paper P in addition to the paper feed cassette 41 having the above-described configuration.
And an external paper supply means 41L (so-called LCT) capable of storing a large amount of transfer paper P in advance. According to the former, it is possible to cope with a case where image formation is specially performed on special transfer paper or OHP, and in the latter, continuous image formation on a large amount of transfer paper P can be performed. .

Although FIG. 1 shows a case in which five sheet feeding means, that is, a manual feed tray 41H and an external sheet feeding means 41L, are provided in the three sheet feeding cassettes 41, the sheet feeding means which can be provided in the present invention. The number of means is not limited in principle. That is, any number of paper feeding means may be provided.

Next, an example of an electric apparatus configuration relating to the copying apparatus having the above mechanical configuration will be described with reference to FIG. Various mechanisms and the like in the above-described image reading unit 10, image writing unit 20, image forming unit 30, transfer sheet transport unit 40, transfer sheet discharge unit 50, and transfer sheet reversing unit 60 are controlled as shown in FIG. The control and control are performed by a central control unit C as a means. Further, an input unit C1 and a page counter C2 are connected to the central control unit C.

The input section C1 is a setting means for performing various settings of the present invention, and also serves as a display means for performing various displays. As the input unit C1, for example, an input unit having a well-known LCD touch panel 90 as shown in FIG. 3 may be employed. The user of the touch panel 9
By pressing and instructing various windows shown on the top of the screen with a finger, setting of copy density, magnification, output of the transfer paper P, and the like can be performed. In such a case,
The input unit C1 also serves as a display unit for transmitting the setting status of the device to the operator.

The input section C1 can perform various page number printing settings described later. For example, it is possible to set a start number (including a negative value) of a page to be printed on the transfer paper P, and to perform, not perform, or skip printing of a page number on copy insertion paper or blank insertion paper. It can be set by either. When actually printing the page numbers,
The mode will be based on the above setting. In any case, these will be described later in detail.

The page counter C2 counts the page number when sequentially assigning a page number to each of a plurality of transfer sheets.

In the following, various forms of control by the central control unit C of the copying apparatus having the above-described configuration will be described with reference to the flowcharts shown in FIGS. In the following description, there are five originals on which images A to E are formed as shown in FIG. 5, and these are sequentially image-formed (copied) on a plurality of transfer papers, and A mode in which numbers are printed will be described as an example.

(Page start number setting function including negative value) This is a function for forming a plurality of original images as shown in FIG. 5 on each of a plurality of transfer papers.
It relates to a function that allows page numbers to be assigned from an arbitrary position on the plurality of transfer papers.

First, as shown in step S1 of FIG. 4, the user of the apparatus uses the input unit C1 to display a screen on which a page number can be set for printing as shown in FIG.
Display above. This screen is displayed on the input unit C1 shown in FIG.
Above, for example, the display may be made by pressing an “applied function” button. In the copying apparatus according to the present embodiment, as shown in FIG. 6, in addition to a page number, a fixed stamp, numbering, date / time (date / time information), and other additional information are printed on transfer paper together with an image. It is possible.

Next, as in step S2 in FIG. 4, a "page" button for entering the "page print mode" setting screen is selected from the above-described additional information shown in FIG. By this selection, a “page print mode” screen as shown in FIG. 7 is displayed. On this screen, “P1, P2,...” And “−1−, −2” shown in the center of FIG.
-, ..., etc., and input the position (top center, center, bottom center, etc.) on the transfer paper P where the page number is to be printed as shown on the right side of FIG. It is possible to set.

Then, as shown in step S3 in FIG. 4, the user selects the "start number" button shown in FIG.
A screen as shown in FIG. 8 is displayed. On this screen, a numerical key 91 is displayed as shown on the right side of FIG. 8, and the user of the apparatus selects the numerical key 91 as appropriate to input a start page number “n” arbitrarily. -Can be set (step S4 in FIG. 4). At this time, the start page number “n” can be set for both a plus value and a minus value. As a method of inputting a negative value, for example, using the arrow keys 92 shown in FIG.
There is a method of sequentially decreasing the value from a plus value (for example, “+5”) and setting a minus value (for example, “−3”). However, in the present invention, it is basically arbitrary how the negative value setting method is actually configured.

As described above, the start page number "n"
Is completed, it is determined whether the set start page number "n" is a plus value or a minus value including zero, as shown in step S5 in FIG.

First, when the start page number "n" is a plus value, the printing mode is basically the same as the conventional one. That is, until the image formation on all the transfer papers is completed, the image formation on the transfer paper P is performed while adding the page numbers sequentially increasing by one from the start page number “n” (FIG. 4). Steps S61, S7, S8). In addition,
The increase of the page number is constantly monitored by the page counter C2. For example, when the page number “n” is assigned to the first transfer sheet, that “n” is stored in the page counter C2 until the image formation of the next transfer sheet, and the image formation for the next transfer sheet is performed. At the time of execution, a page number “n + 1” is assigned (see step S8 in FIG. 4).

For example, when the start page number is “1”, as shown in FIG. 9A, page numbers “1”, “2”,. The images A, B,..., E are formed while 5 ″ is added. When the start page number is “3”, as shown in FIG. 9B, the page numbers “3” and “3” are assigned to each of the five transfer sheets.
The images A, B,..., E while “4”,.
Is formed.

On the other hand, when the start page number “n” is zero or a negative value, only the image formation is performed without printing the page number, as in step S62 in FIG. Note that, in this case as well, step S in FIG.
8, the page count is executed, and step S5 in FIG.
When the page number “n” becomes a positive value in, printing of the page number is started. That is, in the present embodiment, control is performed so that the page number is not printed while the page number is zero or a negative value.

For example, as shown in FIG. 9C, when the start page number is "-1", when the page numbers are "-1" and "0", the page number is not yet a positive value. The printing is not performed, and only the formation of the images A and B is performed. Then, the page number “1” is assigned for the first time on the third transfer sheet. Hereinafter, FIG.
(A) and FIG. 9 (b).

As described above, according to the present embodiment, it is possible to add a page number from an arbitrary position on a plurality of transfer sheets. Conversely, the first page can be assigned to an arbitrary position of a plurality of originals, and the page number printing reflecting that can be executed.

In the above description, the image formation and the page number printing are performed only on the surface of the transfer paper. However, when the double-sided image formation using the transfer paper reversing unit 60 is performed, the page number printing is also performed. It goes without saying that it is performed in a form that matches.

(Page Number Print Setting Function for Copy Insert Paper) This relates to a function that enables setting of page number print for copy insert paper. Here, the copy insertion sheet corresponds to, for example, a transfer sheet inserted by the inter-sheet copy insertion function or a transfer sheet inserted by the chaptering insertion function, and is defined as an insertion sheet on which "image formation is performed". You.

First, steps T1 and T2 in FIG. 10 are exactly the same as steps S1 and S2 in FIG. 4, and the display on the input section C1 is changed in the order of FIGS. 3, 6, and 7. Next, as shown in step T3 in FIG. 10, the “print page” button shown in FIG.
The screen as shown in is displayed. On this screen,
As shown in the middle of the figure, the page number print setting for the copy insertion sheet can be set to one of "print", "not print", and "skip". The apparatus user can set the page number print setting for the copy insertion sheet by appropriately selecting one of these buttons (step T in FIG. 10).
4).

When the page number printing setting is performed as described above, the subsequent page number printing for the copy insertion sheet is performed according to the three settings of “print”, “not print”, and “skip”. The process is different.

First, when "print" is selected, a page number that is continuous with the printing of page numbers on normal transfer paper is also printed on copy insertion paper (step T5P in FIG. 10). Here, the page number printed on the copy insertion sheet is a continuation of the page number assigned to the normal transfer sheet on which an image has been formed before. Further, as shown in step T6C in FIG. 10, the page number printed on the copy insertion sheet is counted by the page counter C2 so as to be continuous with the page number assigned to the entire transfer sheet. That is, the page number printed on the copy insertion paper and the page number printed on the transfer paper following the copy insertion paper are continuous.

For example, as shown in FIG. 12A, there are four normal transfer sheets, and a copy insertion sheet La is inserted between the second transfer sheet PF and the third transfer sheet PR. In this case, the page number “3” is printed on the copy insertion sheet La. The page number is counted by the page counter C2. As a result, the page numbers “2” and “4” are printed on the transfer sheets PF and PR before and after the copy insertion sheet La, and the page numbers printed on all the transfer sheets including the copy insertion sheet La are as a whole. It will be continuous.

If "not print" is selected in step T4 in FIG. 10, the image is formed on the copy insertion sheet, but the page number is not printed (step T5NP in FIG. 10). However, the fact that the copy insertion sheet has been inserted is counted (step T6C in FIG. 10).

For example, as shown in FIG.
When the copy insertion sheet Lb is inserted in the same situation as in 2 (a), no page number is printed on the copy insertion sheet Lb. However, the fact that the copy insertion sheet Lb has been inserted is counted by the page counter C2 since an image is formed on the copy insertion sheet Lb. As a result, the page numbers “2” and “4” are printed on the transfer sheets PF and PR before and after the copy insertion sheet Lb, and the “number” of all the transfer sheets including the copy insertion sheet Lb is represented by the page number. In that sense, it is continuous as a whole.

Finally, when "skip" is selected in step T4 in FIG. 10, image formation is performed on the copy insertion sheet, but the page number is not printed (step T5NP in FIG. 10). The number is not counted (step T6NC in FIG. 10).

For example, as shown in FIG.
When the copy insertion sheet Lc is inserted in a situation similar to 2 (a) and (b), no page number is printed on the copy insertion sheet Lc, and the page number is not counted. As a result, the page numbers “2” and “3” are printed on the transfer sheets PF and PR before and after the copy insertion sheet Lc, and the copy insertion sheet Lc is shown in FIG.
Page numbers are not consecutive as in
As shown in FIG. 12 (b), the state is completely inserted without being continuously determined as the "number".

As described above, according to the present embodiment, it is possible to set a print on a copy insertion sheet, so that various page numbers can be printed.

(Page Number Print Setting Function for Blank Paper Insertion) This relates to a function that enables setting of page number printing for blank paper insertion. Here, the blank paper is
For example, a transfer sheet or the like inserted by the inter-sheet blank sheet insertion function corresponds thereto, and is defined as an insertion sheet in which only a sheet is inserted and an image is not formed.

In this case, as shown in FIG. 13, almost the same operation or processing as the flowchart described with reference to FIG. 10 is performed using the screen of FIG. 11 (see the right side in the figure). become. The difference is that, in the page number print setting for the copy insertion sheet, three types of “print”, “not print” or “skip” can be selected. Then, "do not print" or "skip"
In that it is limited to two types. However, the actual page number printing process after the selection of "not print" or "skip" is performed in the same manner as that for the copy insertion sheet.

From the above, the printing of the page number on the blank paper is, for example, as shown in FIG. 14 (one blank paper is inserted into five transfer papers). That is, FIG.
12A, the page number is not printed on the inserted blank paper Ma, as in FIG. 12B. However, the fact that the blank paper Ma has been inserted is determined by the page counter C2.
Is counted. Therefore, the “number” of all the transfer papers including the blank insertion paper Ma is represented by the page number,
In that sense, it is continuous as a whole. Also, in FIG. 14B, as in FIG. 12C, no page number is printed on the blank sheet Mb, and the page number is not counted. Therefore, the blank sheet Mb is completely "inserted" in all the transfer sheets.

[0057]

As described above, according to the image forming apparatus of the present invention, it is possible to assign the first page to an arbitrary portion of the original, and to set the page number for the copy insertion sheet and the blank insertion sheet. It is possible to make print settings.
