Abstract

PURPOSE:To restrain the number of transfer paper to be equal to or under a standard value number for stapling processing and to automatically execute the copying work of all the originals by counting the number of originals and executing an automatic both-side copying mode when the number of originals obtained as the counted result exceeds the standard value for stapling processing. CONSTITUTION:A height sensor 6 is attached to a side fence 5 provided at the side part of an original table 4. The sensor 6 detects height according to whether light which is emitted from the sensor 6 at the height of T, is intercepted. The T is set by regarding the thinnest paper that can be used in a stapling mode as reference, and a paper bundle which is lower than the T can be stapled. When the number of originals exceeds the standard value for stapling processing, the automatic both-side copying mode is executed and all the originals are copied to the transfer paper whose number is smaller than the number of originals. In the case of detecting that the number of originals is clearly within the standard value, counting the originals is omitted and copying operation is executed immediately, then the original is protected and processing time is improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying system apparatus equipped with an automatic circulating document feeder, a post-processing apparatus and the like.

[0002]

2. Description of the Related Art In the copying system apparatus described above, conventionally, even when the number of originals exceeding the standard value for stapling processing is set in the automatic circulating original feeding apparatus, the copying operation is started and the copy sent to the post-processing apparatus. When the number of completed transfer sheets reaches the standard number for stapling, the copying operation is interrupted.

[0003]

Therefore, in the above-mentioned conventional apparatus, the operator processes the portion after the interruption and restarts it, and the copy paper first sent to the post-processing apparatus is stapled by the operator. However, there is a drawback that the operation becomes complicated.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned drawbacks of the conventional apparatus and to provide a copying system apparatus capable of automatically performing copying work even on a document having a stapling standard value or more. is there.

[0005]

The above-mentioned object is to automatically feed the originals to be copied one after another, form an original image on the transfer paper by a copying process, and perform a stapling process on the transfer paper. 2. Description of the Related Art In a copying system apparatus that performs processing, a document counting unit that counts the number of documents by feeding and discharging a set document once, and the number of documents obtained as a result of the count of the document counting unit is used for stapling processing. When the standard value is exceeded, it is achieved by the first means including a control means for executing the automatic double-sided copy mode.

Further, the above-mentioned object is that, in the first means, a height detecting means for detecting the height of the original is provided, and the control means does not count the number of originals when the number of originals is clearly within the standard value. The second means for controlling the copying operation is performed.

In the first means, when the number of sheets counted by the document counting means is more than twice the standard value of stapling processing, the control means
This is achieved by the third means for controlling so that the copying operation is not performed.

[0008]

According to the first means, the number of originals is counted, and when the number of originals obtained as a result exceeds the standard value of the stapling process, the automatic double-sided copy mode is executed to reduce the number of originals smaller than the number of originals. Images of all originals can be copied onto the transfer paper, which allows the number of transfer papers to be kept below the standard value for stapling within a predetermined number of originals, so copying of all originals is automatically performed. It becomes possible to do.

In the second means, when the height detecting means detects that the number of set originals is clearly within the standard value, the original count is omitted and the copying operation is immediately executed. It is possible to protect originals (generally, when counting the number of originals, all originals are often circulated once, in which case the originals are easily damaged), and the processing time can be improved.

In the third means, when the standard value of the stapling process is twice or more, it is judged that the number of transfer sheets becomes the standard number of the stapling process or more even if the automatic double-sided copy mode is executed. By not performing the copying operation, it is possible to save the time and labor for the unnecessary processing after copying, and thus the workability is improved.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a copying system device.

This copying system apparatus separates and feeds the copying machine 1 and the originals set on the platen one by one, conveys them to a predetermined position of the copying machine 1, and after the predetermined copying process is completed, the originals are copied. Automatic circulating document feeder (hereinafter referred to as R
DH) 2 and a shift tray portion 3a for receiving the copied transfer paper discharged from the copying machine 1 for sorting work.
After the discharged transfer sheets are once stacked on a staple tray, a post-processing device (finisher) 3 including a stapler section 3b for performing stapling processing on the end portions of the transfer sheets 3
It consists of and.

Since both the RDH 2 and the post-processing device 3 are known per se, detailed description of the mechanism and operation will be omitted.

FIG. 2 is an explanatory view showing how the height of the document is detected by the height detecting means.

In FIG. 2, 4 is a document table provided on the RDH 2, 5 is a side fence (or a back fence) provided on the side of the document table 4, and 6 is a height detection attached to the side fence 5. It is a sensor (transmissive or reflective photo sensor). Then, T indicates the detection height of the height detection sensor 6, and light is emitted from the height detection sensor 6 at the height of T, and the light is detected depending on whether or not the light is blocked.

That is, even if a document stack 7 having a height lower than the detection height T is placed on the document table 4, the light is not blocked and the height detection sensor 6 does not detect this. On the other hand, when the original bundle 8 higher than T is placed, the original bundle 8 blocks the light and is detected by the height detection sensor 6. The T is set with reference to the thinnest paper that can be used in the staple mode, and a stack of papers lower than T can be stapled. Therefore, stapling is possible on the transfer sheet that corresponds to the original bundle 7 on a one-to-one basis.

FIG. 3 is a flow chart showing the control contents of the present invention.

First, it is judged whether or not a document is set on the RDH 2, and if it is set (Yes in S1),
It is determined whether or not the automatic double-sided copy mode for automatically copying on both sides of the transfer paper is turned on, and if it is not turned on (No in S2), single-sided copying is started (S
3). If it is on (Yes in S2), then it is determined whether or not the height detection sensor 6 is on (S4). If it is not ON (No in S4), as described above, the document bundle 7 is set, and the corresponding transfer paper can be stapled one-to-one without checking the number of sheets. , Single-sided copy start (S3).

When the height detection sensor 6 is on (Y in S4)
es) As described above, since the bundle of originals 8 is set, the thickness of the transfer paper corresponding to the one-to-one becomes equal to or larger than the standard value of the stapling process as it is. Is performed (S5). If the number of originals is less than twice the standard value for stapling (S
No in 6), it is determined that the number of transfer sheets can be suppressed within the standard value by switching to the automatic double-sided copy mode, and the automatic double-sided copy mode is started (S).
7). On the other hand, if the number of documents is more than twice the standard value (S
(Yes in 6), it is determined that it is no longer possible to deal with the situation by switching to the automatic double-sided copy mode, and the copying operation is interrupted (S).
8).

The document counting means and the control means described in the claims can be controlled by a CPU normally provided in the control section of the copying machine.

According to the above-described embodiment, the original count means for counting the number of originals by once feeding and discharging the set originals, and the number of originals obtained as a result of the counting by the original count means are stapled. When the number of originals exceeds the standard value of the stapling process, the number of originals is counted. By executing the copy mode, it is possible to copy the images of all originals onto a smaller number of transfer sheets than the number of originals, thereby keeping the number of transfer sheets below the standard number of sheets for stapling within a predetermined range of the number of originals. Because you can
It is possible to automatically execute the copy work of all originals.

According to the above-described embodiment, when the height detection sensor 6 detects that the number of originals set is clearly within the standard value, the original count is omitted and the copying operation is immediately executed. Thus, the originals can be protected (generally, when counting the number of originals, all the originals are often circulated once, and in this case, the originals are easily damaged), and the processing time can be improved.

According to the above-described embodiment, when the standard value of the stapling process is twice or more, it is judged that the number of transfer sheets exceeds the standard number of the stapling process even if the automatic double-sided copy mode is executed. By not performing the copying operation, it is possible to save the time and labor for the unnecessary processing after copying, and thus the workability is improved.

[0024]

According to the first aspect of the invention, the number of originals is counted, and when the number of originals obtained as a result exceeds the standard value of the stapling process, the automatic double-sided copy mode is executed to make the originals. Images of all originals can be copied onto a smaller number than the number of sheets of transfer paper, and as a result, the number of sheets of transfer paper can be kept below the standard value for stapling within the specified number of originals. It becomes possible to execute the copying work of.

According to the second aspect of the invention, when the height detecting means detects that the number of set originals is clearly within the standard value, the original count is omitted and the copying operation is immediately executed. By doing so, the original can be protected and the processing time can be improved.
