Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a so-called programmable copying machine, and particularly to a control display device.

(Prior Art) Copying machines that display the time until the end of the copying process when setting the copying mode and during the copying process are known.

Although this technology improves the operator's work to some extent, it also accepts input of multiple subject modes, and the mode! In a copying machine that processes objects sequentially according to the code, displaying the remaining time alone is not sufficient.

In other words, in the above-mentioned copying machine, the total number of copies inputted is expected to exceed the maximum copy paper capacity of the copying machine or the amount of toner that can be copied, and the machine will stop in the middle of copying due to the lack of the above-mentioned supply. It is possible to do so. .

(Purpose) Therefore, there is a need for a function that calculates and displays how many sheets are left for provisional processing before or during copying, and thereby reduces copying interruptions by replenishing supplies, etc. However, the present invention has been made in view of this background, and an object of the present invention is to provide a copying machine having the above-mentioned functions.

(composition) The configuration of the present invention will be explained below based on the illustrated embodiments.

FIG. 1 is a conceptual front view of a copying machine embodying the present invention. This copying machine has various copying modes as shown in the operation section of FIG.

Reduction function, automatic double-sided copying function, sorting, stacking function,
These include multiple pregnancy functions and automatic document feeding functions. The above functions are provided for the purpose of making it more convenient and performing many tasks without operator intervention.

However, the more complex the functions, the more care must be taken to ensure that the operator can use the copier more effectively.

Conventionally, a multi-processing function has been proposed as described above, in which an operator inputs processing for a plurality of objects, and then the copying machine automatically executes the processing for the plurality of objects. In this case, the copying machine performs the processing by itself from several minutes to several tens of minutes, depending on the amount of copy processing given, giving the operator free time during this time.

Therefore, the present invention displays the number of copies to be processed or the copy processing time for a given process to inform the operator of how much free time he or she has.

Also, during processing, the operator is informed from time to time of how many more copies or processing time is required, so that the operator can easily judge whether or not he or she can engage in other work based on the value.

As mentioned above, FIG. 1 is a conceptual front view of the copying form of the present invention.

The field is the time T used to change the reduction rate.

4 and 5 are for explaining multi-item processing input. The following table summarizes the copying process t as an example, and the first work is Ii! shown in Figure 4. Input by order.

First, the JOB key is pressed to enter the multiple processing mode. When entering multi-processing mode, JO to LA (as shown in Figure 6) within 1
B flag F is set.

Next, the number of originals key 13 is pressed to notify input of the number of originals. In this case, input 5 on the numeric keypad 15. When Hara 41IJ & number key 13 is pressed again, Hara, il
'5 The multiple-copy mode is canceled, and the next input from the numeric keypad 15, 10, becomes the number of copies Nc. Continue to press the tray boiling 1 key and reduction rate key 5, and finally press the input key 17 to complete the input of one processing content, and subsequent input will be interpreted as input for the second work. .

The input for the third case is -1 out of the number of manuscripts, as shown in Figure 5.
3 is not pressed. If the button is not pressed, the copying machine determines that the number of original sheets N0 is 1, and the number 100 entered from the numeric keypad 15 means 1 copy &! It is judged as INc.

Continue with key 20 for tray Al. The reduction ratio key 5 is pressed, and finally the input key 17 is pressed to finish inputting the third entry. When all the processing contents are input, each copy mode is sequentially changed from 1 to 1 (A M 4) as shown in Figure 6.
8.

Figure 7 has a different address from Figure 6 It A M 48
Copy mode data when the multi-processing mode is not selected is stored here. Also, when processing multiple items, the data of the number of works being processed is transferred to this address.

Figure 8) This is the content of LAM 48, which includes 4 digits worth of data for each copy that must be processed, and the time (seconds and minutes) used to perform the process. C1ock'+r from the clock oscillation circuits 51 to 54 based on data and an unspecified program: 1 after counting
A timer set-up flag FT, which is set up when the time reaches seconds, and a copy processing time 1o for each copy, which is determined by the program flow described later, are stored.

Next, a description will be given of how the remaining number of copies N and the processing execution time Il+ are determined and how they are determined as the copying process is executed, using the flows shown in FIGS. 10 to 13.

FIGS. 1O and 11 show routines for determining the remaining number of copies N and processing execution time T in various modes. First, the JOB flag F,=l is determined, and if NO, the process jumps to the flow shown in FIG. If Yes, the multi-item processing mode is confirmed.

In the multi-processing mode, pressing the input key 17 is considered to have completed the input for one process, so it is determined that the input key is turned on next. If NO, the routine exits from the N and T determination routine. If Yes, the number of copies Nc and original +
+4 number N. The product is calculated and taken as N1.

Next, the product of +1tc1 and lNI, which has been determined by a per-copy execution time TcI determination routine to be described later, is calculated to determine the actual copying time Tc. 1゛! As mentioned above, is the document exchange time in the automatic lees feeder, and is multiplied with No. to determine the total exchange time T.

Next, it is determined whether the reduction mode of the process being calculated here has changed from the previously input process, and if there is no change, the number of copies N for the previously input process,
It is added to the processing time, and if there is a change in the 6-small mode, the optical system change time T1 mentioned earlier is added to the processing time, which is calculated previously.

It is added as 1゛. Finally, depending on whether the remaining time display key 32 is pressed or not, N or T is displayed on the display elements 39 to 43 in the fitting portion 5.

Figure il1 shows the flow when the multi-processing mode is not in use, and first it is determined whether the ADF mode is in effect. A
If it is not JJk' mode, it is determined whether it is duplex mode. In the double-sided mode, the processing is similar to that in the A1)1/' mode.

Here, double-sided mode is single-sided original #14A, H, C, JJ.
...I fully assumed that I would be making double-sided copies, and the resulting copy would be A on the front, 81 on the back, C# on the back, and KD on the back...
..., and it is assumed that multiple copies of these are requested. This double-sided mode copying is achieved by a known technique, but for example, a copy that has undergone front side copying is not guided to a sorter or output tray, but is guided to a tray inside the copying machine called a buffer tray (not shown). The paper is then re-fed for back-side copying.

That is, if it is considered that there is one more paper feed tray existing in the copying machine main body 1 shown in FIG. 1, there is no factor that causes a special rc4i copying time shadow ia+. It is only necessary to change the original manuscript. Therefore, the processing is the same as in ADF mode.

Al)F, in duplex mode, first check if there is one original sheet,
Or it is determined whether there are multiple sheets. This depends on whether or not the operator is inputting the number of original sheets in the duplex mode. If not, the number of original sheets is displayed. is considered to be 1. Note that whether or not the ADF mode is in effect can be determined based on whether or not there is a document on the automatic document feeder 3.

If No is 1, it is multiplied with the number of copies Nc, and N
If 0=1, Nc itself is the total number of one copy (the number of remaining copies) N.

Continuing, the execution time for each copy is added up, and the actual copying time is 1 hour. I put it on. Next, as in the multi-case processing mode, the number of originals N is multiplied by the original exchange time Ill+. The total execution time T is the sum of 1゛ and Illc. Finally, it is determined whether the remaining time key 32 is (JN or not), and T or N is displayed depending on the determination.

FIG. 12 shows the Tc1 determination routine described above, which is processed every time the tray keys are turned on.

In other words, if any of the tray keys is (JN), 56
The status of a size detector such as .about.57 is input, and the vapor size corresponding to the selected tray key is determined. Tc based on its size! is selected from it (J M 47 and stored in a predetermined position in RAM 48).

FIG. 13 shows how N or r determined by copy mode data input in various input modes is subtracted by executing the copy process. First, as described above, FIG. When the timer set-up flag F is determined and set up, data for T+s 1 second is subtracted from F.
, the flag is reset.

-Next, it is determined that the paper ejection sensors 58 to 59 are ONt, and if Yes, the value of N is subtracted by 1. Next, it is determined whether or not the remaining time key 32 is turned on, and if the key is not turned on, N is displayed. If the key force is 1ON, it is determined that N=Q. When there is an error force of 1 between the disaster time of the copy process and the subtracted 'v', N
This is because if the value becomes 0, the error calculation is forcibly set to 'v=0. And Ill show all.

(Effects) The main point is as described above, and according to the present invention, the operator can easily determine how long the automatic processing will continue by simply checking the display. Since the total number of copies per copy is small, it can also be used as information for replenishing paper, toner, etc. In other words, if you replenish the toner, etc.
The mechanical car never stops on the way.

Furthermore, the changeover switch allows you to select and check the number of remaining copies and one hour of remaining copies as appropriate, and it is also possible to correct errors in the number of remaining copies and one hour of remaining copies caused by various factors.
