Abstract

PURPOSE:To make improvements in an operating property by installing an interleaf inserting means, inserting a sheet of print paper in the midway on the basis of the number of pages inputted, and inputting an insert spot of the interleaf through the page number. CONSTITUTION:Since any image formation on a sheet of interleaf is prohibited when a finishing copied state is on both sides, even if this interleaf is fed out of a manual feed tray 5a, an image form processing part is not operated at all, so that it is discharged onto a paper discharge tray 7 as leaving an image unformed intact on this interleaf. A page number of interleaf insertion is inserted from a ten-key. Whether there is an even-numbered page in the inputted page number or not is judged, and if there was the even page, 1 is subtracted from the even page, resetting it to an odd-numbered page, and it is advanced to a copying routine at which the interleaf of colored paper or the like being set to the manual feed tray 5a is inserted into a spot before the set page.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to an image forming apparatus having an inserting paper inserting function for inserting interleaving papers of different colors or the like into the middle of a plurality of sheets of printed paper for partitions.

[1)) Prior Art For example, when copying a document classified by item using a copying machine, it is convenient to insert sheets of different colors (referred to as interleaf sheets) at the boundaries of each item.

For example, an automatic document feeder is used to automatically feed documents one after another. ) was inserted in advance, and the automatic document feeder detected the slip sheet and inserted the slip sheet at that position.

On the other hand, in recent years, devices have been developed that automatically feed double-sided printed documents (duplex automatic document feeder) and devices that flip the paper from front to back in order to print on both sides of the paper (front-side reversal device). original) - one-sided (copy), one-sided -
Duplex, duplex-single-sided, duplex-duplex, etc. copying can be performed automatically.

(C1 Problem to be Solved by the Invention) However, in the case of inserting slip sheets, in the method of inserting a slip sheet into a document as described above, a slip sheet is inserted into the document before copying, and the slip sheet is inserted into the document after copying. There was a problem in that the number of pages in the finished copy may be incorrect or blank pages may be incorrect depending on the combination method such as one-sided copying and one-sided copying. There were problems such as making too much.

FIGS. 5A to 5E are diagrams showing examples of copying with slip sheets inserted. The same figure (A) is one side - one side, the same figure (B), (C) is one side - both sides, the same figure (D) is both sides -
One side, (E) shows an example of double-sided → double-sided copying, the slip sheet is placed in front of the 3rd page except for (C), and (C) is the 4th page.
It is inserted at the front of the page. As shown in the figure, if the finished image is single-sided (A) or (D), double-sided (B)
), (C), and (D) are all images of different formats, and there is no uniformity. Therefore, the user has to insert the slip sheet while considering the finished state according to the pattern of the document at that time, and it is very difficult for the user to understand the pattern, making it difficult to fully utilize the device and causing mistakes in copying. It often occurred. In addition, in case (B), the page becomes distorted from the next page after inserting the insert (the front page is an even numbered page), and in case (C), insert paper should not be inserted. There is also the inconvenience that the back of the third page becomes blank.

The purpose of this invention is to improve operability by inputting the number of pages where inserting sheets are to be inserted, and also to provide a slipping paper insertion function that prevents processing errors by adding constraints to the inserting conditions. An object of the present invention is to provide an image forming apparatus having the following features.

(d) Means for Solving the Problems This invention provides an inserting sheet inserting means for inserting interleaving sheets of different colors etc. into the middle of the printed paper based on the input number of pages, and a method for inserting interleaving sheets into the interleaving sheets during double-sided printing. The present invention is characterized by providing means for prohibiting printing, and means for prohibiting insertion of slip sheets before even-numbered pages.

te1 Effect In this invention, the position at which an insert sheet is to be inserted is entered in terms of page number, and the insert sheet is inserted into the manually entered page. FIGS. 1(A) to 1(C) are diagrams showing examples of the finished state of images when copying with inserted inserts is performed, and (A)
) is one side - one side, (B) is one side - both sides, (C) is both sides -
One side, (D) is a double-sided → double-sided copy, and the third page (
A slip sheet is inserted before the input page). It can be seen that the images are formed in the same state when the finished image is on one side (A) and (C), and when it is on both sides (B) and (D). In other words, an insert is inserted before the input page number, so there is no need to insert multiple sheets at once, and in the case of double-sided copying, an insert is inserted before even-numbered pages. Since there are no blank pages, there is no need to create extra blank pages or get the number of pages out of order.

In this method, the number of pages is input, so even in a laser printer or the like, insert sheets can be inserted based on the input pages.

('') Embodiment FIG. 2 is a schematic 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 top surface of the copying machine body. The document on the document table 1 is scanned by the optical system 2, and its reflected light is guided to the photoreceptor 3. A double-sided document automatic feeder 4 is provided above the document table 1 . The double-sided document automatic feeder 4 has a document tray 4a.
, a document feed belt 4b, and a discharge section 4C. The original set on the original tray 4a is transported by the original feeding belt 4b.
The document is stopped at a predetermined position on the document table 1, 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 ejection section 4c, but if it is a double-sided original, the original passes over the original feeding belt 4b and is sent to a predetermined position on the original platen 1 again. As a result, the front and back sides of the original are reversed, and both sides of the original are scanned. The document is then discharged to the discharge section 4c.

The photoconductive body 3 is a photoconductive body formed in the shape of a drum, and a known electrophotographic process device including a charger, a developer, etc. is provided around the photoconductive body, and constitutes an image forming process section. A paper feed section 5 including a manual feed tray 5a and paper cassettes 5b and 5c is provided on the right side of the main body of the copying machine. A sheet of paper is sent from either the manual feed tray 5a or the paper cassettes 5b, 5c to the image forming process section, and an image is formed thereon. In addition,
When inserting interleaving paper, insert paper is generally inserted into manual feed tray 5.
Set to a.

A front-back reversing device 6 is provided below the image forming process section. The surface reversing device 6 includes a flap 6a2 and a reversing portion 6b.
, an intermediate tray 6c, and a paper transport section 6d. The flap 6a distributes the paper sent from the image forming process section to the paper output tray 7 or the front/back reversing device side, and transfers the paper to the reversing section 6.
b uses the switch hack method to turn the paper upside down. The intermediate tray 6c is a tray for temporarily stocking paper, and the paper transport section 6d operates to transport the paper on the intermediate tray 6c to the image forming process section.

To give a specific example of a copying operation, for example, in the case of one-sided/single-sided copying, the one-sided original on the original tray 4a is centered downward, and then sent onto the original table 1. Further, the paper is fed from the paper feed section 5, an image is formed on one side, and then the flap 6a
The paper is ejected to the paper ejection tray 7 side. For example, both sides
In the case of double-sided scanning, one side of the original on the original tray 4a is first scanned, and an image is also formed on one side of the sheet fed from the paper feeding section 5. Then, the original is reversed and placed on the original table l again to be scanned, and the sheet of paper is reversed in the reversing section 6b and then sent to the image forming processing section where an image is formed on the reverse side. Single-Sided-Double-Sided Copy 1Double-sided-Single-Sided Copy is a combination of the above operations.

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

The operation when inserting an insert in the copying machine configured as described above will be explained. FIG. 4 is a flowchart showing the processing procedure when inputting an insert page.

First, when the chapter mode is set by operating the chapter key 11, a question about the type of copying method (one-sided - one-sided copy, 9 one-sided -, double-sided copy, etc.) is displayed on the LCD panel 8, as shown in FIG. Ru. The desired copying method can be input accordingly (nl, n2). If the finished state is double-sided copying using the manual copying method, that is, one-sided-double-sided copying or two-sided-double-sided copying, proceed to n4 and enter the r insert page. The insert is inserted just before the input page. ” and r Since it is a double-sided copy, it cannot be copied onto insert paper.

" is displayed. That is, when the finished copy is double-sided, image formation on the insert is prohibited. Therefore, when forming an image, the interleaving paper is placed in the manual feed tray 5.
When paper is fed from a, the forming process unit does not operate and the paper is delivered to the paper output tray 7 without any image being formed on the paper.
is discharged to.

The number of pages to be inserted is inserted using the numeric keypad 1o.

If there are several positions where insert sheets should be inserted, any number of pages can be registered by operating the tab key. At n5, it is determined whether or not there is an even number of pages among the manually entered page numbers. If there is an even page, 1 is subtracted from the even page number to set it as an odd page (n6), and the process proceeds to the copying routine.

In the copying routine, an interleaf such as colored paper set in the manual feed tray 5a is inserted in front of the set page (see FIGS. 1(B) and 1(D)).

Therefore, for example, even if you input 3 pages manually or 4 pages, a slip sheet will be inserted before the 3rd page in the finished state, resulting in extra blank spaces and pages starting from the next page. The numbers won't go crazy. Furthermore, since image formation (printing) on the interleaf paper is prohibited, pages will not be misaligned.

Note that in this embodiment, if the number of input pages is an even number, it is automatically converted to an odd numbered page and a slip sheet is inserted before the odd numbered page. may be omitted so that only odd-numbered pages are input.

If the finished copying state is one-sided copying, a manual decision is made in step n7 as to whether or not to copy the insert paper. If copying is to be done on insert paper, please enter the r insert insert page in n8. The specified page will be the insert.

'' is displayed, and when the number of pages is input from the numeric keypad 10 (n8), an insert sheet is fed at the designated page and the copying process is performed. In this case, the interleaf paper is ejected with an image formed on one side, and the interleaf paper does not pass through the front-back reversing device 6. Aigi colored paper is thicker than the paper normally used for copying,
Jams tend to occur when the paper passes through a front-back reversing device.

However, in this device, the interleaving paper does not pass through the front-back reversing device, which prevents jamming. In addition, if the copy is not made on insert paper, please enter r insert insert page. The insert is inserted just before the manual page. j will be displayed, and if you press the page manually from the numeric keypad 10, a match will be inserted just before that page number. In this case, the number of pages may be odd or even, and an insert will be inserted immediately before that page.

(g) Effects of the Invention As described above, by imposing restrictions on the insertion method when inserting inserts, it is possible to prevent discrepancies in the number of pages and the creation of blank pages. Furthermore, since the user does not need to think of a different operation method to suit the pattern at that time, there is an advantage that operability is improved. Furthermore, since the number of pages for inserting slip sheets is input and insert sheets are inserted accordingly, the effort of inserting slip sheets can be saved, and the system can also be used in image forming apparatuses such as laser printers.
