Abstract

PURPOSE:To permit a continuous job in simple manners by carrying out a copying treatment according to the succeeding job when one between the preceding job and the succeeding job to be executed next is the supply of paper from an accommodation part in which the papers having different kind from that in the other job are accommodated. CONSTITUTION:If paper is accommodated into a bin according to the preceeding job when one between the preceeding job and the succeeding job to be executed next is a one side copying mode and the other is a both side copying mode, the copying treatment according to the succeeding job is permitted, and the paper after copying is discharged into the bin. Therefore, the succeeding job can be carried out in simple manners.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a method for controlling a copying machine with a sorter.

(Prior Art) There is a copying machine with a sorter that has a function of sequentially discharging copied sheets into each bin.

In such copiers, when a new job is executed while copies of paper that have already been processed by a previous job are left in the bin, the paper from the previous job overlaps with the paper from the subsequent job, making it difficult to identify them. , separation becomes difficult. In order to eliminate this inconvenience, a control method has been adopted in which copy processing is not executed for a new job when there is paper from a previous job in the bin.

In addition, if you select the mount mode after the previous job has finished, you can make copies using a new job even if there is paper left in the bin.
A control method has been proposed in which a new job, that is, a subsequent job, is then executed. In this case, since it is possible to distinguish between the two jobs using the mount, there is no problem even if the subsequent job is executed.

(Problem to be Solved by the Invention) In a conventional copying machine with a sorter, even if it is possible to distinguish between the sheets of each subsequent job, for example because the paper sizes are different, the paper of the preceding job must be removed from the bin. It is not possible to execute a follow-up job, which makes the operation complicated for the operator.

Further, the technique for setting the mount mode requires various equipment to execute the mode, resulting in a complicated configuration.

A ninth object of the present invention is to provide a control method for a copying machine with a sorter that allows continuous jobs to be easily performed using a WJ-YA configuration.

(Means for Solving the Problems) In order to achieve the above object, in the control method of the present invention, when sheets of paper from a preceding job are stored in a bin, the preceding job ε If one of the jobs involves feeding paper from a storage unit containing paper of a different paper type than the other, copy processing can be performed by the following job, and the copied paper is ejected to the bin. We decided to control it so that

If the bin contains paper from a preceding job, and one of the preceding job and the succeeding job to be executed is in single-sided copy mode and the other is in duplex copy mode, It is preferable to enable copying processing by row-copying and control the copied paper to be discharged to a bin.

(Operation) When the copied paper sent to the bin by the succeeding job can be distinguished from the copied paper stored in the bin by the preceding job, the succeeding job is executed.

(Example) An example of a copying machine with a sorter suitable for implementing the present invention is shown in FIG. 6. Since the present invention relates to a control method, the mechanical configuration shown in FIG. The configuration is similar to that of a seed device.

Therefore, detailed explanation will be omitted and only the main points will be described.

Regarding the copying machine body 15, ADF (Auto Doc
(umentFeedar) 1 is a fully automatic document feeder that automatically feeds and circulates the document to the exposure section. 5
ADF (Semi-Auto Document F
eeder) is a semi-transferable document feeder used when setting and copying documents one by one. When copying, the R document is irradiated with the xenon lamp 3. The reflected light passes through a mirror M and a lens L, and is imaged and exposed onto a belt-shaped photoreceptor 5, which has been charged in advance by a main charger 4, to form a latent image. This latent image is visualized in a developing section 6, and further, this developed image is transferred to a transfer paper in a transfer separation section 7. After the transfer, the transfer paper is separated from the photoconductor 5 and reaches the fixing section 8, where the image is fixed and transferred to the copy tray 9.
Alternatively, it is discharged into each bin 10b of the sorter 10.

The above is a case of front-side copying, but in the case of Wi-side copying, the transfer paper on which front-side copying has been performed according to the above process enters the duplex tray 11, where it is reversed. Thereafter, the paper is again fed from the duplex tray 11 toward the transfer/separation section 7 for back side copying. When the transfer paper that has been subjected to double-sided copying is discharged to the sorter 10, the pages are arranged in the same order.

On the way, the bottle 10 is turned over at the reversing section 12 with the surface facing up.
It is stored in b.

By the way, there is a paper feed section that stores uncopied transfer paper.
000 sheet tray 13A, 13B, 250 sheet cassette]・1
Four accommodating sections, 4 and 3000 sheet large trays 15, are prepared, and sheets are fed to the transfer/separation section 7 from any of these accommodating sections.

Control of this system is performed by a CPU 16 shown in FIG. Copy work instructions and the like to the CPU 16 are performed through an operation section 18 provided at an easily visible position on the main body of the copying machine.

The operating section 18 has keys arranged as shown in FIG. 4, and various displays. In Fig. 4, tray selection keys (13A), (13B), (14), (
15) are the 1000-sheet trays 13A and 1 in Fig. 6, respectively.
3B, 250-sheet cassette 14. Corresponds to 3000-sheet large tray 15. In the example shown in the figure, 1000-sheet tray 1
B5 size for 3A, B4 for 1000 sheet tray 13B
Size, 250 sheets Cassette 14 has A4 size, 300 sheets
The 0-sheet large tray 15 accommodates each A3 size transfer paper. If you press one of these tray selection keys, the CPU 1 will feed paper from the corresponding tray.
6, the control system is ready.

As for the copy density, if no operation is performed, the automatic density adjustment function will work, and if the a degree designation button 19 is pressed at a desired level, that density will be selected. To specify magnification, press the button 21, and then press any of the buttons 22 such as "Zoom", "Enlarge J", or "Reduce J". Each time you press the button, the magnification ratio will change and be displayed on the display 23. Therefore, you can specify the desired rate.

To specify the double-sided copy mode, press the button 24, to add a binding margin, press the button 25, and to use the sorter 10, press the button 26 to specify the mode. If button 24 is not pressed, one-sided copy mode is designated.

Example 1 (see Figure 1) The 250-sheet cassette 14 is registered in the CPU 16 as a special tray, and color transfer paper is stored in this tray.Therefore, for the preceding job, 10 sheets of A4 size originals are printed at the same size. Suppose that you are instructed to copy 20 copies. In this case, the sorter 10 is used, and by pressing the button 26, the sort mode is executed, and the copied transfer paper is stored in all the bins from the 1st to the 200th bin of each bin 10b. Become.

Next, for the subsequent job, if there are 5 A4-sized originals and you want to copy them at the same size in the IO section, and on color transfer paper, that is, on a different paper type, specify these conditions as the copy conditions for the job. . In the prior art, the sorter 10 is programmed in such a way that the copying process for the subsequent job cannot be executed unless the transfer paper related to the previously copied job is removed from the sorter 10.

In this example, when a special tray containing transfer paper of a paper type different from that of the preceding job is selected, instruction information to that effect is sent to C.
The information is transmitted to the PU 16, and copy processing can be performed immediately, and the data can be discharged to the sorter IO. Even if this is done, since the copied transfer paper related to the subsequent job has a different color from the copied transfer paper related to the preceding job, it can be identified even if they are overlapped on the bin, and no problem will occur.

Such control is executed by the CPU 16 according to the flowchart shown in FIG. As shown in this flowchart, in the above example, if a special tray is not selected, the copy process is not executed and a warning message is transmitted to the operator by lamp or voice.

Example 2 (See FIGS. 1 and 2) In Example 1, the subsequent job can be executed by selecting a special tray. In this case, the special tray stores the preceding job and paper types, that is, color transfer paper of different colors.

In this example, transfer sheets of different paper types, that is, sizes, from the preceding job are stored in a special tray, and the subsequent job is executed by selecting this special tray.

For example, the 3000-sheet large tray 15 is registered as a special tray in the CPU 16, A3 size transfer paper is stored in this tray, and 20 copies of 10 sheets of A4 size originals at the same size for a preceding job are stored in the CPU 16. Suppose that a copy of is specified and executed. In this case as well, A4-sized copied transfer paper is stored in each bin in accordance with the above example. In the subsequent job, there are 5 A3 size originals, and 1 at the same size.
If copying on A3 size transfer paper, which is the same size as the original, is specified as a copy condition for a job, in the prior art, the subsequent job cannot be executed unless the copy of the previous job is removed from the bin. , according to this example, can be executed according to flowchart 1 shown in FIG.

Alternatively, as a modified example, the size of the transfer paper in the subsequent job compared to the preceding job is detected and compared, and if the sizes of the transfer paper in both jobs are different from each other, the paper is fed from the tray containing the transfer paper. The present invention can also be implemented according to the flowchart of FIG. In this case, the size of the transfer paper in the selected tray can be detected by a sensor and automatically registered in the CPU 16, or the size of the paper to be stored in each tray can be manually registered in the CPU 16. A method of registering in advance may also be used.

Example 3 (See FIG. 3) This example enables subsequent jobs due to the difference in copy mode.

If the original is 10 sheets of A4 size and 20 copies are to be one-sided copied at the same size, the above example is followed, and the transfer paper copied in the one-sided copy mode is one copy from the 1st bin to the 20th bin. It will be stored.

Next, if there are 10 A4-sized originals and 10 double-sided copies are to be made at the same size, the copy is executed in the double-sided copy mode. In the prior art, copying cannot be performed unless the copied transfer paper is removed from the sorter.

In this example, the flowchart shown in FIG. 3 is followed.

Since the preceding job is in single-sided copy mode and the succeeding job is in double-sided copy mode, they are different from each other, so they can be copied immediately and are discharged to the sorter. As a result, the bin 10b of the sorter stores transfer sheets for single-sided copying and duplex copying, but since the copying conditions are different, the jobs can be easily identified.

It goes without saying that copying is also possible when the preceding job is in double-sided copy mode and the succeeding job is in single-sided copy mode.

What all of the above embodiments have in common is that copies can be made immediately without removing the transfer paper from the sorter bin. Moreover, it is possible to distinguish between jobs by the difference in paper type and whether it is a single-sided copy or a double-sided copy.

Another advantage is that even if there are few bins, many jobs can be copied immediately.

(Effects of the Invention) According to the present invention, continuous jobs can be easily performed with a simple configuration.
