[0002]

2. Description of the Related Art In a conventional image forming apparatus, for example, a colored sheet or the like is used as a cover and an image of the original is automatically placed on the top of a copy original group which is one copy of a copy original recorded on the paper. A cover insert mode such as a cover mode to be arranged or a chapter break mode to automatically arrange each chapter of a copy original group as a chapter break sheet is provided.

FIG. 8 shows an example of an arrangement relationship between a copy original and a cover in the cover mode and the chapter break mode. FIG. 8A shows an arrangement of the cover 80 and the copy original 81 in the cover mode, and FIG. 8B shows an arrangement of the cover 80 and the copy original 81 in the chapter break mode. However, the arrangement in the chapter break mode is not limited to that shown in the figure, and how many cover originals are to be inserted into the group of copy originals, and how many copy originals 81 are between the cover Whether or not to arrange them can be freely set.

In general, when copying in the cover mode or chapter break mode, when a plurality of copies are designated, that is, when a plurality of copy manuscript copies are designated, the cover and the copy manuscript are sorted using a sorter. ,
It is necessary to use an automatic document feeder (hereinafter, referred to as ADF) and a post-processing device (hereinafter, referred to as sorter). However, if the sorter as a post-processing device is in an abnormal state, as in the case where a copy remains in front of the bin of the sorter and the sorting process is not accepted, and the operator does not notice this abnormality, even if the cover is inserted, Even if the copying is performed in the mode, the sorting operation must be performed by the operator himself after the copying is completed, and there is a problem that the operability is poor.

In order to solve the above problems, Japanese Patent Laid-Open Publication No.
In the “recording control device” described in JP-A-73193, the sort mode is automatically set when the cover insert mode is set. At this time, the state of the sorter is constantly monitored, and if an abnormality is detected, the setting of the cover mode is prohibited. Therefore, if the sorter enters an abnormal state, the cover insertion mode is not established. Therefore, even if the operator attempts to set the cover insertion mode without noticing the abnormality of the sorter, that is, the post-processing means, the use prohibition of the post-processing means is immediately determined. Since it is possible, the operator himself does not need to manually perform post-processing for bookbinding after copying as in the related art, which improves operability.

[0006]

However, in the above-described apparatus, if the sorter is in an abnormal state, even if it is in the cover insertion mode when only a part of the copy document is needed, the copy is performed using the sorter. Since an attempt is made to perform the operation, if there is an abnormality in the sorter, even if it is not necessary to use the sorter, an error due to the sorter abnormality, that is, the cover insert mode is prohibited, and a copy cannot be obtained in the cover insert mode. There is a problem that.

The present invention has been made in view of the above problems, and sets the post-processing means only when the number of copy originals is two or more when the cover insertion mode is designated, that is, when the post-processing means must be used. The present invention provides an image forming apparatus capable of improving operability in the cover insertion mode by not performing meaningless warning due to abnormality of the post-processing unit and prohibiting operation of the cover insertion mode.

It is an object of the present invention to provide an image forming apparatus capable of performing the following.

Further, even after the cover insertion mode and the post-processing means are set and the number of copies of the copy document is set to two or more, the number of copies of the copy document is reset to one by the clear key or the like. In such a case, the setting of the post-processing means is automatically released to improve the operability in the cover insertion mode without performing a meaningless warning due to the abnormality of the post-processing means and prohibiting the operation of the cover insertion mode. It is an object of the present invention to provide an image forming apparatus capable of performing the following.

Next, the operation of the image forming apparatus according to the present invention will be described with reference to FIG.

When making a copy by pressure plate copying, an operator places an original on the contact glass 8 and discharges the original from the contact glass 8 after the copy of the original is completed.

When copying is performed by setting a bundle of originals on the ADF 27, the ADF 27 guides the originals one by one onto the contact glass 8 and automatically discharges the originals from the contact glass 8 after the copying of the originals. Do it. The cover may be placed on the ADF.

The original on the contact glass 8 is scanned by a carriage integrated with the first mirror 1 and the illumination lamp 7. The reflected light image passes through the first to third mirrors, the lens 6, the fourth mirror 4, and the dustproof glass 9, and is formed on the photosensitive drum 11 rotating to a fixed position.

The photosensitive drum 11 is driven by a main motor 12. At this time, the leading end of the image is a portion after the position where the control unit has passed the cleaning unit 13. After the photosensitive drum 11 is charged by the charger 15, the eraser 16 irradiates unnecessary parts with light to form an image frame suitable for paper or a projected image, and then forms a latent image on the photosensitive drum 11 by a reflected light image. To form At this time, in order to obtain a 1: 1 image, the photosensitive drum 11 and the carriage are driven at the same speed.

The latent image on the photosensitive drum 11 is visualized as a toner image by the developing unit 17. At this time, a dark or light image can be obtained by applying a potential to the developing unit 17.

The paper P is sent to the registration roller 20 by the paper feed roller 18, and the registration roller 20 is moved when the leading edge of the toner image on the photosensitive drum 11 and the leading edge of the paper match.
To the transfer charger 21.

The toner image on the photosensitive drum 11 is transferred to the sheet P by the transfer charger 21. Since the surface of the photosensitive drum 11 is smooth and has high adhesion to the paper, the separation charger 22 lowers the potential of the paper P to reduce the adhesion between the photosensitive drum 11 and the paper P. Thereafter, the sheet P is separated from the photosensitive drum 11 by a separation tab 23, and the separated sheet P is sent to a fixing roller 25 by a transport belt 24. Here, heat and pressure are applied to the toner, and the toner image is fixed on the sheet P to form a copy document. The copy document is discharged to the sorter unit 28.

The sorter unit 28 copies copy originals discharged from the copying machine body one copy per copy original bundle in which copy originals are arranged in the same page order as the original document arrangement in the original bundle. , Or the number of pages specified for each page of the copy original corresponding to the pages of the original in the bundle of originals, the first page n, the second page n,.・ Send them together. When one copy, two copies, and so on are arranged in each of the output paper bundles in which the copy originals are arranged in the same page order as the original document arrangement in the original bundle, the staples 29 can be used to bind the originals. I can do it.

FIG. 5 is a flowchart illustrating a first operation of the image forming apparatus according to the present invention. In this embodiment, the chapter separation mode is selected as the cover insertion mode,
A case where a sorter is used as the post-processing means will be described. However, the same operation can be performed even if the cover mode is selected and another post-processing means is used.

First, in step S1, it is confirmed whether or not the chapter break mode is set. If not set (No), the operation ends. If the chapter break mode has been set (Yes), the flow shifts to step S2 to check whether or not the number of copies is two or more. If the number of copies is not two or more (No), the process proceeds to step S4, the copy is performed in the chapter break mode without setting the sort mode, and the operation ends. If the number of copies is two or more in the confirmation in step S2 (Yes), the process proceeds to step S3, where it is determined whether or not the sorter is usable. Set the sort mode, copy in chapter break mode, and end the operation.

Therefore, in the first operation, when the number of copies of the copy document is two or more, the sort mode is operated to perform the operation in the chapter separation mode, and when the number of copies of the copy document is one, the sort mode is used. Is set, the chapter break mode operation is performed. If the sorter has an error when the number of copies of the copy is two or more, the chapter break mode is prohibited. Also, when the number of copies of the copy is one, the operation in the chapter separation mode is performed without operating the sorter, so that the operability of the operator can be improved.

FIG. 6 is a flowchart illustrating a second operation of the image forming apparatus according to the present invention.

First, in step S5, it is confirmed whether or not the chapter break mode is set. If not set (No), the operation ends. If the chapter break mode has been set (Yes), the flow shifts to step S7 to check whether or not the sorter is usable, that is, whether or not the sorter is abnormal. No), and it transfers to step S13. Step S13
, It is confirmed whether or not the number of copies is two or more. If the number of copies is not two or more (No),
The process proceeds to step S15, where the copy in the chapter break mode is performed without setting the sort mode, and the operation ends. If the number of copies is two or more (Yes), the process proceeds to step S14, in which the number of copies is forcibly limited to one copy, and a copy is performed in the chapter separation mode without setting the sort mode (step S15). Finish.

In the confirmation of whether or not the sorter can be used in step S7, if the sorter is usable (Ye
s) Then, the process shifts to step S9 to check whether or not the number of copies is two or more. If the number of copies is not two or more (No), the process proceeds to step S10, where copying in the chapter break mode is performed without setting the sort mode, and the operation ends. If the number of copies is two or more (Yes), the flow shifts to step S11 to set the sort mode, perform the copy in the chapter break mode, and end the operation.

In step S10, if the sorter is usable and the number of copies of the copy is one, the operation in the chapter separation mode, that is, the copy is performed without setting the sort mode. The mode may be set for copying.

Therefore, in the second operation, the sorter is first checked for abnormality, and if there is no abnormality in the sorter, the copy mode in the chapter-separation mode is operated. Check whether this is the case. If the number of copies is one, the operation in the chapter separation mode is performed without setting the sort mode. Even if the number of copies is two or more, the number of copies is reset to one. Since the operation in the chapter break mode is performed without setting the sort mode, copying in the chapter break mode is not prohibited even if the sorter has an abnormality, so that the operability of the operator can be improved.

FIG. 7 is a flowchart illustrating a third operation of the image forming apparatus according to the present invention.

First, in step S17, it is confirmed whether or not the chapter break mode is set. If not set (No), the operation ends. If the chapter break mode is set (Yes), step S19
Then, it is confirmed whether or not the number of copies is two or more. If the number of copies of the copy is not two or more (N
o), the process proceeds to step S20, in which the chapter break mode is set without setting the sort mode, and copying is performed, thus ending the operation. If the number of copies is two or more (Ye
s) The process moves to step S21, and the sort mode is set. In step S23, it is confirmed whether or not the number of copies has been cleared, that is, whether or not the number of copies has been corrected to one.
Then, copying is performed in the chapter break mode with the sort mode set, and the operation ends. If the number of copies of the copy document has been corrected to one, the process proceeds to step S25 to reset, that is, cancel, the sort mode.
Then, the process proceeds to step S20, where the chapter break mode is set without setting the sort mode, and copying is performed, and the operation is completed.

In FIG. 7, the sorting mode is set in step S21 to confirm whether or not the number of copies of the original is two or more, as in step S21, and the number of copies of the original is cleared to one. The process is performed during the step S23 for checking whether or not the copying has been performed. For example, a step S17 for checking whether or not the chapter break mode is set, and whether or not the number of copies of the copy original is two or more. This step may be performed between step S19 and the step S19 for confirming the above.

Therefore, in the third operation, after confirming whether or not the chapter break mode is set, it is confirmed whether or not the number of copies of the copy document is two or more, and if the number of copies of the copy document is one, If it is a copy, the operation in the chapter break mode is performed without setting the sort mode. If the number of copies of the copy document is two or more, the sort mode is set, and thereafter, it is confirmed whether or not the number of copies of the copy document has been reset to one, that is, reset. If it is reset, it operates in chapter break mode without setting the sort mode.If it is not reset, it operates in chapter break mode with the sort mode set. However, when the number of copies of the copy original is set to one copy or reset to one copy, the copy operation in the chapter break mode is performed without prohibiting the operation in the chapter break mode. Performance can be improved.

In the above-described embodiment, the case where a sorter is used as a post-processing device for transporting a specific sheet such as a cover to an appropriate position for paper ejection and the sorter is abnormal has been described. Is not limited to the sorter abnormality as the abnormality of the post-processing apparatus. For example, even if there is an abnormality in the post-processing apparatus such as a staple unit, the number of copies of the copy document is one as described above. If the number of copies is two or more, the copy is limited to one copy without using the post-processing device, and the post-processing mode is reset when the number of copies is cleared. Therefore, it can also be used in a chapter break mode using an arbitrary post-processing device.

[0049]

As is apparent from the above description, according to the present invention, when the number of copy originals when the cover insertion mode is designated is two or more, that is, only when the post-processing means has to be used, Since the processing means is set and the meaningless warning due to the abnormality of the post-processing means and the operation of the cover insert mode are not prohibited, the erroneous operation of the operator can be prevented when the post-processing means has an abnormality, Further, when the number of copies of the copy is one, even if there is an abnormality in the post-processing means, it is possible to perform copying in an appropriate cover insertion mode, so that operability can be improved.

Further, if there is an abnormality in the post-processing means in the cover insertion mode, even if the number of copy originals is two or more, that is, the sorter mode must be used,
Since the number of copies of the copy document is limited to one copy and no meaningless warning due to the abnormality of the post-processing means and the operation prohibition of the cover insert mode are not performed, one copy of the document group copied in the cover insert mode can be secured. At the same time, the operability in the cover insertion mode can be improved.

Further, even after the cover insertion mode and the post-processing means are set and the number of copies of the copy document is set to two or more, the number of copies of the copy document is reduced to one before the copy operation is performed. When the setting is made, the setting of the post-processing unit is automatically canceled, and the meaningless warning due to the abnormality of the post-processing unit and the operation of the cover insertion mode are not prohibited, so that the operability in the cover insertion mode is improved. Can be done.
