Abstract

PURPOSE:To prevent a trouble of the occurrence of paper jam during original feeding by checking whether the number of all used originals exceed the capacity of an original automatic feeding device or not in case of multijob copying. CONSTITUTION:A magnification varying key 14 and a ten key 16 for input of the number of copies are depressed to input data of the number of copies, the magnification, etc. with respect to the first set of original sheets, and copying conditions are inputted similarly with respect to the next set of original sheets. When a copy button 19 is depressed after condition setting for many sets of original sheets is terminated, copying is automatically performed in prescribed conditions for individual sets. If the number of used original sheets exceeds the capacity of the original automatic feeding device on the way of input of conditions, a message indicating this state is displayed on a display device 15 to warn an operator of this state.

Description

Detailed Description of the Invention (Technical Field) The present invention provides a multi-job copying machine equipped with an automatic document feeder and a T-combiner. It relates to a copying machine that sets a mode and performs copying operations sequentially for each document, and in particular,
This relates to the control device.

(Prior Art) Conventional copying machines perform a single job that repeats the cycle of "inputting data such as the number of copies and variable magnification for a set of originals, and copying based on the input data." Copy machines were the mainstream. However, with such a single-job copying machine, after copying one set of originals, the operator must input data for the next set of originals and start copying, so the operator must always stand by near the copying machine. I had to do it.

This method does not improve the efficiency of copying work, and therefore involves the preparation of multiple manuscripts. Number of copies of each, variable magnification 1
Multi-job copying machines have been proposed that are capable of storing input data such as collation mode and perform copying operations based on the stored data, and efforts have been made to improve the efficiency of copying operations.

However, in conventional multi-job copying machines, the number of originals that can be installed in the automatic document feeder and the number of bins that can be used in the collating device are different from the number of yX documents required for multiple input copying operations and the number of bins that can be used in the collating device. Because I did not check the number of bins,
If the operator is not careful, the number of originals that can be placed may be exceeded, resulting in a document jam in the ADF, or all the bins in the collating device may become full during a series of copying operations, causing the collating device to fail. There was a drawback that the collating operation could not be controlled and jams could occur. Therefore, the operator must always pay attention to the number of original sheets and the number of bins.

(Purpose) The present invention has been made in view of the above-mentioned conventional drawbacks, and is aimed at counting the number of original sheets used in a multi-job copying machine based on input data related to a series of copying operations. The purpose of this device is to compare the number of originals that can be placed on the automatic document feeder and give a warning, thereby preventing document jams caused by placing an excessive number of originals and reducing copying work. It is.

3 and 4 are flowcharts of the main program showing the operation of the copying machine of the present invention. In FIG. 3, "key manual processing" is the same as in a general copying machine, when the input of the data necessary for the copying operation, such as the number of copies, variable magnification, etc., is completed and the start key 19 is pressed or the multi-job key 25 is pressed. Pushed,
Ends when multi-job mode is selected. Next, if the multi-job mode is not selected, that is, if the start key 19 is pressed, the copying process ("Normal mode copying process") is performed based on the input data, and the copying process ends. Then, "key human processing" again
Do the following. Also, if multi-job mode is selected,
As shown in Figure 3.2, the total number of originals SD, the number of used pins SC is set to O, the job counter JN is set to 1, and the number of originals that can be installed in the ADFI (hereinafter referred to as original capacity) is set to 0. CD), and the number of usable bins of the collating device 3 (
CC (hereinafter referred to as bin capacity) is communicated with each control unit.
``Perform an initial reset.''

Next, data for one copy operation is temporarily saved. Variables (number of originals DN, number of copies CN, both mode flag MFI,
Perform a "variable reset" to reset the collation mode flag (MP2, etc.) to ○.

Next, ``multi-mode key manual processing'' is performed to input data necessary for the copying operation.

In the "multi-mode key manual processing", the input number of originals and number of copies are stored in DN and CN, respectively.

In addition, when each mode is selected by the duplex mode key 23 or the composite mode key 24, MF1 is set to 1 and 2, respectively.
Set to . Further, when the collation mode is selected by the sort mode key 21 or the stack mode key 22, MF2 is set to 1°2. "Multi-mode key manual processing" is performed when at least the original page number DN and the number of copies CN are manually input (1 or more) and the input key 28 is pressed, or the multi-job key 25 is pressed and the multi-job mode is canceled. or when the start key 19 is pressed. Next, when the multi-job key 25 is pressed,
The "key manual processing J" in FIG. 3 is performed again. When the start key 19 is pressed again, it is determined whether data for one or more copying operations has been input (JN>1), and if the data has not been input. (JN=1), performs "multi-mode key manual processing" again, and if input has already been performed, the saved data Already number of originals DN (+), number of copies 0N(i), duplex mode flag MFI (i) Based on the collation mode flag MF2(i), etc., a series of copying operations ("multi-mode copying process") are performed up to i=1st work JN-1st work. In addition, if at least the number of original sheets DN and the number of copies CN are input and the input key 28 is pressed, the number of original sheets DN
, number of copies CN1, duplex mode flag Mi1. Based on the collation mode flag MF2, the optimum collation mode is selected, the collation mode flag MF2 is changed, and "mode selection" is completed.

Next, from the number of originals ON, the number of copies CN, the number of bins used in the main copying operation and the number of originals DN determined based on the duplex mode flag MFI and the collation mode flag MF2, the entered information including the number of originals for the main copying operation is determined. The total number of original sheets used in copying operation SD and the total number of bins used SC are calculated as the original capacity CD.
A "capacity check" is performed which ends by displaying or canceling a capacity over warning by comparing it with the bin capacity CC.

cormorant. Next, if the capacity is exceeded, "multi-mode key manual processing" is performed again. Also, if the capacity is not exceeded,
Number of originals required for this copying operation DN.

Data such as number of copies CN, duplex mode flag FMI, collation mode flag MF2, etc. are set to DN (JN) and CN, respectively.
(JN), MFI (JN), MF2 (JN), etc., and count up the job counter JN (+1

N, MFl, MF2. J.N.

DN (i), CN (i)MFl (i), MF2
(i), SC, SD, CD, CC, etc. are stored and saved at predetermined addresses in the RAM 13.

FIG. 5 is a detailed flowchart of the "mode selection" subroutine of FIG.

In FIG. 5, if the number of originals DN is 1, the collation mode is set to stack, that is, MF2=2. Further, if the number of original sheets DN is not 1, and the number of copies CN is 1, the collation mode is set to sort, that is, MF2=1. Also, if the duplex mode flag MF1 is not 0, that is, duplex mode or composite mode is selected, and the number of originals is DN.
If is 2, the collation mode is set to stack, MF2=2.

The above operation is set unconditionally even if collation mode is input in "Multi-mode key manual processing" in Figure 4, so for example, if the number of originals DN = 10 and the number of copies CN =
Even if you select stack mode (MF2=2) as 1,
In this subroutine, sort mode (MF2=1)
Therefore, the number of bins in the collection bag [3 used during the main copying operation during the copying process is 1 instead of 10. Therefore, as the number of bins used by the collating device 3 is reduced, more data for copying operations can be input.

The copy processing time for a series of copy operations becomes longer. During this time, the operator can perform other tasks, making the copying process more efficient and semi-unmanned.

In cases other than the above, if a collation mode is input (MF2≠0), the selected collation mode is given priority, and if no collation mode is input, the collation mode is sorted, that is, MF2= Set to 1. Therefore, since the operator does not necessarily have to select the collation mode, there is an effect that the operation work is reduced and the working time is shortened.

6 and 7 are detailed flowcharts of the "capacity check" subroutine of FIG. 4. In FIGS. 6 and 7, if the single collation mode is sort, that is, MF2=1, the number of copies CN is added to the total number of used bins SC. If the collation mode is not sort, that is, MF2 = 1, and the duplex mode flag MFI is 0, the total number of used bins SC is equal to the number of originals D.
N is added. Also, if the duplex mode flag MFI is other than O, duplex mode (MF1=1) or composite mode (MF
1=2) is selected, and if the number of original sheets DN is an even number, ON/2 is added to the total number of used bins SC, and if it is an odd number, (DN+1)/2 is added.

Next, if the added total number of bins in use SC exceeds the bin capacity CC, "Collation device capacity exceeded" is displayed on the display 15, and the number added above is subtracted from the total number of bins in use SC. A "collation device capacity over warning" will be issued.

If the amount has not been exceeded, the message "Collating device capacity exceeded" will no longer be displayed.

Next, the number of originals DN is added to the total number of originals SD, and if the added total number of originals SD exceeds the original capacity CD, "Original capacity exceeded" is displayed on the display 15,
The added number of original sheets DN is subtracted from the total number of original sheets SD. "Original capacity over warning" will be issued. If the amount has not been exceeded, "original capacity over warning cancellation" is performed so that "original capacity over" is no longer displayed.

As described above, each time data related to a copying operation is input, the document capacity and bin capacity are checked. There is no need to pay attention to the bottle capacity,
In addition, since it is possible to utilize the capacity of the copying machine to the maximum, it is effective in reducing copying work and increasing efficiency.

(Effects) According to the control device according to the present invention, the number of document sheets (CD) that can be installed in the automatic document feeder connected to the copying machine is detected, and the number of document sheets (CD) that can be installed in the automatic document feeder connected to the copying machine is inputted from the input means and stored in the storage means. Based on the data related to the series of copy operations, the number of original sheets (SD) used in the series of copy operations is counted, and the number of original sheets (SD) used in the series of copy operations is counted.
By comparing the SD and SD and displaying the results on the display means, document jams due to overloading of documents can be prevented. Furthermore, since the operator does not need to be careful about exceeding the capacity of original documents, there is also the effect that the copying work is reduced.
