Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image forming system, and more particularly to an image forming system provided with an electrophotographic apparatus such as a copying machine and an automatic document feeder capable of conveying a computer form paper document.

[0002]

2. Description of the Related Art Conventionally, an image forming system having an electrophotographic apparatus, for example, an apparatus for automatically conveying a copy original on a contact glass of a copying machine has been widely used. There is a document feeder which conveys a continuous document such as so-called computer form paper (hereinafter, also simply referred to as CF paper) (Japanese Utility Model Publication No. 64-9954, Japanese Utility Model Publication No. 2-91742, and Japanese Utility Model Publication No. 2-91742). See Kaihei 2-7244, etc.).

CF paper is a continuous document divided into a plurality of pages by perforations, and it is common to fold and print a long printed sheet of paper in a Z shape. In the automatic document feeder described above, CF paper is used. The original is conveyed and stopped in order from the leading end side in units of a predetermined amount, and each page of the original is set on the contact glass in response to the copying operation of the copying machine.

[0004]

However, in such a conventional image forming system, continuous CFs are used.
It is difficult to securely fold and place the original on the paper ejection tray on the side of the copying machine while ejecting the original.
There is a problem that it is easy to continue copying while the CF document is in a drooping state. Further, it is difficult to manually fold a CF document that has not been properly placed on the discharge tray. For this reason, the copying work using the CF original has extremely poor workability.

On the other hand, for example, Japanese Utility Model Laid-Open No. 64-9954
As described in Japanese Patent Publication No.
It may be possible to guide the F document so that it can be folded properly. However, even if this is done, it is not possible to accommodate all document sizes, and if the first document is not folded properly, the subsequent document will not be printed. The problem remains that it cannot be folded properly. On the other hand, computer form paper is required to be continuous paper in order to support continuous printing. However, printed CF paper often does not need to be stored as continuous paper, and conversely, is cut appropriately. In some cases, it may be better for the print surfaces to face in the same direction.

The present invention pays attention to the fact that it is not necessary to store the CF originals in series, and by adding a function of separating the CF originals to the automatic original feeding device, copying work for the CF originals can be performed. The purpose is to improve workability.

[0007]

In order to achieve the above object, the invention according to claim 1 illuminates and scans a document set at a predetermined document setting position to form an image corresponding to the image of the document. An electrophotographic apparatus, and a document feeding section which is provided on the electrophotographic apparatus and which feeds a plurality of pages of computer form paper originals continuous through perforations from one end,
Also, an automatic document feeder having a document transport unit that transports the document from the document feeding unit in a predetermined transport direction by a transport member and stops the document, and sequentially sets a portion corresponding to each page of the document at the document setting position. An image forming system including: a pair of at least one pair of rollers facing each other across a part of the continuous document in the document feeding section; and a driving unit that drives the pair of rollers in the document transport direction. The braking means for braking the roller pair, and the original conveying means are operated while the roller pair of the original feeding section is being braked by the braking means to feed one or more pages of originals and originals on the original setting position side. A driving unit, a braking unit, a document feeding unit, and a document are provided so that the subsequent document on the side of the paper unit is separated from the perforations, and the document on the side of the separated document setting position is discharged before the subsequent document is fed. Transport section A control means capable of executing the document division control is provided, and the invention according to claim 2 is an electronic device for the document when the document division control is executed by the control means. Selective means for selecting whether or not to perform illumination scanning of the photographic device is provided, and the continuous document can be cut into a plurality of sheets by executing the document division control without the illumination scanning. According to a third aspect of the present invention, the control means causes the original document feeding section and the original document conveying section to generate a continuous original document in accordance with the number of pages of the original document fed by the original document feeding section. It is characterized in that it is possible to switch between a first transport mode in which the document is transported as it is and a second transport mode in which the document division control is executed.

[0008]

According to the first aspect of the invention, when the control means executes the document division control, the document conveying means is operated while the roller pair of the document feeding portion is braked by the braking means, and the document setting position side 1 is set. The page or a plurality of pages of the original document and the subsequent original document on the original document feeder side are separated from the perforations, and the subsequent original document is fed after the separated original document on the original document setting position side is ejected. Therefore, it is not necessary to continuously fold the discharged originals, and the discharged originals can be easily stacked, and the workability of the copying operation on the continuous originals (CF originals) is significantly improved.

According to the second aspect of the present invention, when the document division control is executed, if the selection means selects the illumination scanning, the image formation corresponding to the continuous document is executed and the illumination scanning is not performed. If selected, the continuous document is separated into a plurality of sheets by the automatic document feeder controlled by document division without forming an image. Therefore, the function of the automatic document feeder is expanded.

According to the third aspect of the invention, the first transport mode in which the continuous document is transported as it is by the document feeder and the document transport unit according to the number of pages of the document fed by the document feeder, and the document A second transport mode for executing division control,
It can be switched by the control means. Therefore, the continuous original can be divided into lengths corresponding to the desired number of pages.

FIGS. 7 and 8 show screens of the touch panel 200 which constitutes a part of the input means of the copying machine main body 1.
In the screen of FIG. 7, when the manuscript size is designated by the four key portions 201 to 204, the paper is automatically selected. When the user selects the manuscript size on this screen, it is shown in FIG. The screen is changed as follows. In the screen of FIG. 8, the CF document transport mode is selected and input by using the three key portions 211 to 213 based on the display "Please select the document transport mode", and sequentially in page order. Three types of conveyance modes: a normal mode for conveying, a one-page division mode for dividing the CF original by one page by executing the original division control, and a two-page division mode for dividing the CF original by two pages by executing the original division control. One of them is selected. The next message "Do you want to copy?" Is due to the default function, usually "YES" key 215
Is pressed. If the user who has selected the one-page division or the two-page division only wants to cut the document, the "NO" key 216 is pressed. If "NO" is selected here, the copying operation by the copying machine body 1 is not performed.
When the normal "YES" is selected, the user then sets the number of copies with a numerical input key (10 key) (not shown) and presses the print key (not shown).
The copy operation and the document conveying operation are executed.

That is, the touch panel 200 includes the CPU 100
When the document division control is executed by the copy machine control device 102, the copy machine main body 1 for the CF original document is executed.
Has a function of selecting means for selecting whether or not to perform the exposure operation (illumination scanning) of the CP.
The U100 and the control device 102 can execute the document division control without illuminating and scanning the document by the copying machine body 1 to separate (divide) the CF document into a plurality of sheets. In addition, by selecting input on this touch panel 200, CP
The U100 and the control device 102 operate in the normal mode (first transport mode) in which the CF document is directly transported by the document feeder 10 and the document transport unit 15 according to the number of pages of the CF document fed by the document feeder 10. ) And the second conveyance mode ("one page division" and "two page division" modes) for executing the document division control can be switched.

Next, the operation will be described. FIG. 9 is a schematic flowchart of a control program executed by the copying machine-side control device 102. In the figure, first, it is checked whether the CFF mode is selected (step S1).
), If the CFF mode is selected (if "YES"), the mode content selection work for the document size, the transport mode, etc. on the touch panel 200 is displayed, and the content is selected by the user (step). S2). Then
It is checked whether or not all the contents of the selected mode are confirmed (step S3), and if confirmed (if "YES"), the fact that the CFF mode is selected and the document size information thereof are transmitted to the ADF2. (Step S4).

Next, it is checked whether or not the print key is pressed (step S5), and if it is pressed ("Y"
If "ES"), it is checked whether or not the feeding operation of the CFF original is necessary (step S6).
Since the page has already been set on the contact glass 14, the paper feeding operation is not necessary, but in this case (when the determination result in step S6 is "NO"), step S11 described later is performed.
Proceed to. When the paper feeding operation is required (if "YES"), the type of the original document feeding (normal CF original document feeding or cut feeding for cutting to the next page and feeding) is determined (step S7
), A paper feed command is issued to the ADF 2 according to the determination result. That is, when the "normal mode" is selected on the screen of FIG. 8, a paper feed command is issued (step S8),
When "one page division" is selected, a disconnection command is issued (step S9). When the document size is small (for example, 8 1/2 ")," 2-page division "may be selected. In that case, if the next document to be fed is an even-numbered page, a paper feed command is issued. (Step S8) If the odd-numbered page, the cutting and feeding command is issued (Step S9).

Thereafter, after waiting for the feeding completion signal from the ADF 2 (step S10), it is checked whether or not the copying operation is necessary after the feeding is completed (step S1).
1) If necessary ("YES" is selected in FIG. 8), the copy operation is executed under the set conditions (step S12). Next, the presence or absence of the next page original is checked depending on whether or not the original end signal is sent from the ADF 2 (step S13). If the next page original is present, the next cycle is started. If the original end is reached, the ADF 2 is set to the CFF mode. An end signal is transmitted, and this processing ends.

FIG. 10 is a schematic flowchart of a control program executed by the CPU 100 of the ADF 2.
In the figure, first, when the CF document detection sensor 81 is turned on, that is, when the leading end side of the CF document is detected (step S31), a signal notifying the document setting state is transmitted to the copying machine side control device 102 ( Step S32). Then
It is checked whether the CFF mode has been entered (step S
33) After entering the CFF mode, it is checked whether or not there is a paper feed command or a cut paper feed command (steps S34, S35).

At this time, if there is a paper feed command, first, the conveyor belt motor 60 and the reversing motor 61 are driven (O
N), the electromagnetic brake clutch 65 is turned off, and the conveyance belt motor 60 is driven to drive the CF document feed roller pair.
The CF original is conveyed to 46 and conveyed (step S3).
6). Next, it is checked whether the number of holes counted by the perforation detection sensor 82 has reached a predetermined number according to the document size (step S37). If "YES", the conveyor belt motor 60 and the reversing motor 61 are stopped. After that (step S38), a signal notifying the completion of document feeding is sent to the copying machine-side control device 102 (step S3).
9). Next, it is checked whether or not the CF document detection sensor 81 is OFF (step S40). If the CF document detection sensor 81 is OFF, a signal notifying the document end state of the CF document is sent to the copying machine-side controller 10.
2 (step S41), and waits for the next original to be set. If the CF document detection sensor 81 is not OFF, CFF
It is checked whether the mode has ended (step S42),
If the CFF mode is not finished, move to the next cycle, C
If the FF mode ends, the current process ends.

On the other hand, when the cut and feed command is issued, the conveyor belt motor 60 and the reversing motor 61 are driven (ON) and the electromagnetic brake clutch 65 is turned ON (step S43). At this time, the CF document feed roller pair 46
Since the drive of the conveyor belt motor 60 is not transmitted to the motor and the brake is applied by the electromagnetic brake clutch 65, the CF
The subsequent page original (subsequent original) sandwiched between the drive-side large-diameter roller 46a and the driven-side small-diameter roller 46b of the original feeding roller pair 46 is held in the original feeding section 10 while being stopped. Therefore, when the document of the previous page on the contact glass 14 is about to be conveyed by the document conveying section 15 in the paper discharge direction, C
A force to pull the two pages apart is applied to the F document, and the CF document is cut at the perforated portion between the two pages.

During this time, it is checked whether or not the discharge sensor 35 is turned from ON to OFF (step S44), and the cut front page document is discharged from the ADF 2 to the outside of the machine and the result of this check becomes "YES". Then, the processing from step S36 onward is executed, and the next page original is fed. As described above, in the present embodiment, the copying machine side control device 102 and the CP of the ADF 2 are
When U100 and the document division control are executed, the document feeding section 15 is operated while the CF document feeding roller pair 46 is braked by the electromagnetic brake clutch 65, and the contact glass 14 is pressed.
One or a plurality of pages of the original manuscript feeding unit 10 and the subsequent manuscript on the side of the manuscript are separated from the perforations, and the separated front page original is ejected, and then the rear page original is fed. It
Therefore, the discharged CF original can be made into one page or a plurality of short originals (a plurality of sheets) for a predetermined number of pages while continuously feeding the CF originals, and the CF originals are continuously supplied. Eliminates the need to fold. As a result, it becomes possible to easily stack the discharged CF originals,
The workability of copying a CF document is significantly improved.
Further, in this embodiment, when the document division control is executed, the “YES” key 215 and the “NO” key 21 of the touch panel 200 are
Whether or not the copying operation is performed is selected by 6, and if "YES" is selected according to the selection result, image formation corresponding to the CF original is executed, and if "NO" is selected, image formation is performed. Without (without illumination scanning), the CF document is separated into a plurality of sheets by the ADF 2 that is controlled to divide the document. Therefore, it is possible to add the function of executing only the division of the CF document to the function of the ADF 2 to expand the function. Further, in this embodiment, according to the number of pages of the CF document fed by the document feeding unit 10, the normal mode in which the CF document is fed as it is by the document feeding unit 10 and the document feeding unit 15, and the document division. Since the mode can be switched to the one-page division mode or the two-page division mode for executing the control, the CF original can be divided into a plurality of sheets having a length corresponding to a desired number of pages.
