DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming apparatus having a slip-sheet inserting function for inserting sheets of different colors in the middle of a plurality of print sheets for partitioning.

[0002]

2. Description of the Related Art For example, when copying a document classified by item in a copying machine, it is convenient to insert sheets of different colors (called interleaving paper) at the boundary of each item. For example, in order to insert a slip sheet in a copying machine in which a document is automatically fed sequentially by using an automatic document feeder, conventionally, colored paper or a sheet having a special code hole (referred to as a slip sheet) at a position where the slip sheet is to be inserted. Is inserted, and an automatic document feeder detects the slip sheet and inserts a slip sheet at that position.

On the other hand, in recent years, a device for automatically feeding a double-sided printed document (double-sided document automatic feeding device) and a device for inverting the front and back sides of a sheet for printing on both sides of the sheet (front and back reversing device) have been developed. , 1-sided (original) → 1-sided (copy), 1-sided → 2-sided, 2-sided → 1-sided, 2-sided → 2-sided, etc. can be automatically copied.

[0004]

However, when inserting a slip sheet, in the method of inserting a slip sheet into an original as described above, the slip sheet is inserted into the original before copying, and the slip sheet is inserted after copying. Since it had to be removed, there was a problem that double labor was required. In addition, depending on the combination method such as single-sided copying or double-sided copying, there are problems that the number of pages of finished copy is messed up, or blank pages are additionally formed.

FIGS. 5A to 5E are diagrams showing a copy example in which a slip sheet is inserted. The same figure (A) is one side → one side, the same figure (B), (C) is one side → both sides, the same figure (D)
Indicates a double-sided → single-sided copy example, (E) shows a double-sided → double-sided copy example, and the slip sheet is in front of the third page except for (C).
(C) is inserted before the fourth page. As shown in the figure, when the finished image is one-sided (A), (D), both sides (B), (C), (D) have different format images, and there is no uniformity. .

Therefore, the user needs to insert the slip sheet in consideration of the finished state according to the pattern of the document at that time, and it is very difficult for the user to grasp the pattern, and the user cannot make full use of the device and make a mistake. Copying often occurred. Also,
In the case of (B), the page is misaligned from the page after the slip sheet is inserted (the front surface is an even page), and in the case of (C), the third page in which the slip sheet should be inserted. There is also the inconvenience that the back side of is blank.

The object of the present invention is to improve the operability by inputting the inserting position of the slip sheet by the number of pages and to limit the conditions for inserting the slip sheet. In the case of copying, an image forming apparatus having a slip sheet insertion function capable of preventing the occurrence of a processing error by allowing the input of either the even number or the odd number of the specified pages of the slip sheet and prohibiting the input of the other The purpose is to provide.

[0008]

An image forming apparatus having a slip-sheet inserting function of the present invention includes an insert-page input means for inputting the number of pages for inserting slip-sheets having different colors, and an input by the insert-page input means. A slip sheet inserting means for inserting the slip sheet before the specified number of pages, and when printing on both sides of the sheet, the number of pages input to the insert page input means is either an even number or an odd number. An image forming apparatus having a slip sheet inserting function, characterized in that means for allowing only input and setting as the number of pages for inserting a slip sheet is provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 is a schematic configuration diagram of a copying machine which is an embodiment of the present invention.

A document table 1 made of transparent glass or the like is provided on the upper surface of the main body of the copying machine. The document on the document table 1 is scanned by the optical system 2, and the reflected light is guided to the photoconductor 3. Above the platen 1, an automatic duplex document feeder 4 is provided. The double-sided automatic document feeder 4 is provided with a document tray 4a, a document feed belt 4b, and a discharge section 4c. The document set on the document tray 4a is stopped at a predetermined position on the document table 1 by the document feed belt 4b, and is scanned by the optical system 2 as described above.

If the original is one-sided, the original is ejected as it is to the ejecting section 4c. However, in the case of a double-sided original, the original passes through the upper side of the original feeding belt 4b and is fed again to a predetermined position on the original table 1. . This will reverse the front and back of the original,
Both sides of the document will be scanned. Then, the original is ejected to the ejection unit 4c.

The photoconductor 3 is a photoconductor formed in a drum shape, and a known electrophotographic process device including a charger, a developing device and the like is provided around the photoconductor 3 and constitutes an image forming process section. A paper feed unit 5 including a manual feed tray 5a and paper cassettes 5b and 5c is provided on the right side surface of the copying machine body. Paper is sent to the image forming process unit from any of the manual feed tray 5a and the paper cassettes 5b and 5c to form an image. When inserting a slip sheet, the slip sheet is generally set on the manual feed tray 5a.

A front / back reversing device 6 is provided below the image forming process section. The surface reversing device 6 includes a flap 6
a, a reversing section 6b, an intermediate tray 6c, and a sheet conveying section 6d. The flap 6a distributes the paper sent from the image forming process section to the paper discharge tray 7 or the front / back surface reversing device side, and the reversing section 6b reverses the front / back surface of the paper by a switchback method. The intermediate tray 6c is a tray for temporarily stocking paper, and the paper transport unit 6d operates to send the paper of the intermediate tray 6c to the image forming process unit.

In the case of a specific copying operation, for example, in the case of one-sided → single-sided copying, the one-sided original on the original tray 4a is set face down and is sent to the original table 1. Further, the sheet is sent from the sheet feeding section 5 and an image is formed on one side thereof, and then is ejected to the sheet ejection tray 7 side by the flap 6a. Also, for example, in the case of double-sided → double-sided, one side of the document on the document tray 4a is first scanned, and an image is also formed on one side of the paper fed from the paper feeding unit 5. Then, the document is turned upside down, set again on the document table 1 and scanned, and the sheet is turned upside down 6b.
After being inverted, the image is formed on the back side by being sent to the image forming process section. Single-sided → double-sided copying and double-sided → single-sided copying are combinations of the above operations.

FIG. 3 is a partial plan view of the operation panel on the upper surface of the copying machine main body. A liquid crystal panel 8 on which a message is displayed during operation, a selection key 9 for selecting an operation according to the display, a numeric keypad 10, a chapter (insert slip-sheet) key 11
Etc. are provided.

The operation of inserting a slip sheet in the copying machine configured as described above will be described. FIG. 4 is a flowchart showing a processing procedure at the time of inputting a slip-sheet insertion page.

First, when the chapter mode is set by operating the chapter key 11, the liquid crystal panel 8 asks a question about the type of copying method (single-sided → single-sided copying, single-sided → double-sided copying, etc.) as shown in FIG. Is displayed. According to this, the desired copying method may be input (n1, n2). If the input copy method is for double-sided copy, that is, for single-sided → double-sided or double-sided → double-sided copying, proceed to n4 and enter "insert slippage page." The slip is inserted just before the input page. ] And “Since this is a double-sided copy, it cannot be copied onto a slip sheet. Is displayed. That is, when the finished copy state is double-sided, image formation on the slip sheet is prohibited. Therefore, at the time of image formation, when the slip sheet is fed from the manual feed tray 5a, the forming process unit does not operate, and the sheet is discharged to the sheet discharge tray 7 without an image formed on the slip sheet. The number of pages for inserting slip sheets is inserted from the ten-key pad 10.

When there are several positions where the slip sheet is to be inserted, the number of pages can be registered by operating the tab key.

That is, it is judged whether or not the page designated by n5 is an odd page, and if it is an odd page, copy start is performed, and if it is not an odd page, the page is re-input.

In the copying routine, the slip sheet set in the manual feed tray 5a is inserted before the set page (see FIGS. 1B and 1D).

Therefore, no extra blank space is created and the number of pages from the next page is not changed.
Further, since image formation (printing) on the slip sheet is prohibited, the pages do not shift.

When the finished copy state is one-sided copy,
At n7, an input is made as to whether or not copying is performed on a slip sheet.
When copying onto slip sheet, n8 "Please enter the slip sheet insertion page. The specified page becomes the slip sheet. Is displayed and the number of pages is input from the ten-key pad 10 (n8), a slip sheet is fed at the designated page and a copy process is performed.

That is, it is determined whether the first page designated by n10 is an odd page, and if it is an odd page, the process proceeds to the next step, and it is determined whether the next page designated by n11 is an even page. , If it is an even page, proceed to n12
Judge whether the next page specified in is an odd page,
If it is an odd page, then copying is started in sequence if it is an odd number, an even number, ...

Therefore, the designated pages are odd, even, odd, ...

In this case, an image is formed on one side of the interleaving paper and the interleaving paper is ejected, and the interleaving paper does not pass through the front / back reversing device 6. Colored slip paper is thicker than paper that is usually used as copy paper, and jams are likely to occur when it passes through a reversing device. However, in this apparatus, jamming is prevented because the slip sheet does not pass through the reversing device.

If the copy is not made on the slip sheet, "Please enter the slip sheet insertion page." The slip is inserted just before the input page. Is displayed and a page is input from the ten-key pad 10, a slip sheet is inserted immediately before the page number. In this case, the number of pages may be odd or even, and a slip sheet is inserted immediately before the page.

[0027]

As described above, by restricting the insertion method when inserting the slip sheet, it is possible to prevent the number of pages from being misaligned and blank pages from being formed. Further, there is an advantage that the operability is improved because the user does not need to consider an operation method according to the pattern at that time.

Further, in the case of double-sided copying, an interleaving paper is not inserted before even-numbered pages, so that an extra blank sheet portion is not formed and the number of pages is not changed.

Further, even in the case of single-sided copying and copying onto slip sheets, an extra blank sheet portion is formed or the number of pages is changed because the insert pages of the slip sheets are sequentially designated. There is no end.
