This operation is repeated 3 times hereafter.

Description

[Detailed description of the invention] (Technical field) The present invention relates to a copying method.

(Conventional technology) Visible image transfer type copying devices are well known.

Normally, Chen's copying apparatus can use a plurality of types of transfer paper having different sizes. So, when copying two or more manuscripts? , Copying simultaneously on the same transfer paper, for example, copying two manuscripts in column A, number 3, on the same transfer paper at the same time, is done in Japan. ing. Copy as shown above as an example. Row 5: ( is an A4 original 2
All you have to do is place the sheets side by side and make a copy using A3 transfer paper.

On the other hand, in recent years, automatic document feeders have become widespread, and copying machines having automatic document feeders have become common.

However, with conventional copying machines equipped with self-help document feeding devices, it was not possible to copy the second original onto the same transfer paper using the original and corner automatic feeding devices. In the case of a 4-copy device, in order to copy multiple originals on the same transfer paper (in other words, multiple originals must be placed side by side on the original 1 holding glass, the function of the automatic document feeder is If you feed the originals one by one and place them in the specified position on the original platen glass. I can't send it.

(Purpose) The present invention has been made in view of the above-mentioned circumstances, and its purpose is to use an automatic document feeder (.℃), and to transfer a document from +i to −Q+ ) Provision of a new copying method that allows copying onto transfer paper.

(false) The tea invention will be explained below.

In order to realize the present invention, the copying device must have an automatic document feeder and be of a visible image transfer type. The length must be greater than or equal to the maximum transcription length.

The maximum transfer paper is the maximum length of the plurality of four transfer papers used in the copying machine. Regarding the transcription paper and manuscript, the length is unknown? +In Book F, what is the length of the photoconductor in the circumferential direction? (・U. In other words, regarding a document, the length of the document refers to the length of the document, regardless of whether it is in the longitudinal direction or the width direction of the document itself.When an electrostatic a1 number corresponding to the document is formed on the photoreceptor, this latent image In relation to the photoconductor, the circumferential direction of the photoconductor; (the length of the document in the corresponding direction) is defined as the document length LO.

Similarly, the length L of the transfer paper refers to the length of the transfer paper corresponding to the direction of the photoreceptor's length after the town sight marks on the photoreceptor are transferred.

Now, the feature of the present invention lies in the following π.

When copying multiple originals onto the same i-type copy paper, the length L of the transfer paper, the number n (≧2) of originals to be copied on the same transfer paper, and the length LO of the original are specified. be done.

d The copying magnification is fixed at the same magnification (
・When -=X, the closest p to XVc among the WB smaller than
This is the maximum number of originals that can be simultaneously copied on transfer paper of length L0', and the above value of n is within the range of 2≦n≦p, and the copying person or
Allow the reproduction device to select.

If the copy magnification is variable and the minimum copy magnification is n)D, then -=Y, oL
□ Among the integers smaller than Y, the one closest to Y copies the original of length LO onto transfer paper of length L at the same time.
This is the maximum number of manuscripts that can be created, and is 1' of the above n! It is 2≦
The copying person or the copying device selects within the range of n≦q.

In other words, the value of n can be determined by the person doing the copying, depending on L and LO, or by specifying L and LO to the copying machine, and the copying machine automatically calculates the above value. Alternatively, p or q may be calculated and determined as p or q f n.

On the other hand, eight originals (S≧n) are placed in the automatic original feeder.

The automatic document feeder feeds the documents one by one according to the specification, n, and LO, and places the documents one after another on the document placement glass. Of course, only one document is placed on the holding glass at a time.

Then, the position of the line light on the photoconductor is controlled for each document, and 0 sheets of original images are formed adjacent to each other on the photoconductor. The process of developing the d latent image and transferring the obtained irJ visual image onto the same transfer paper is repeated until all m originals are sent.

For example, if you specify n=3 according to L and LO and place 11 originals on the automatic document feeder, the automatic document feeder will first feed the first document and then of,
Install the VC at a predetermined position on the document placement glass. Subsequently, a line of light is applied to the photoreceptor, and an electrostatic latent image corresponding to the first document is formed.

Subsequently, a second document is sent and placed at the predetermined position. At this time, the first document is ejected from above the document placement glass. Then, an electrostatic latent image corresponding to the second document is formed. At this time, the exposure position on the photoreceptor is controlled, and the electrostatic latent images of the original and the original of the spear 2 are adjacent to each other on the photoreceptor without overlapping with the electrostatic latent images of the original of the spear 1. . Similarly, when the 66th original is sent and a corresponding latent image is formed,
On the photoreceptor, the electrostatic capacitors corresponding to the originals J-1, 1-2, and 6 are formed so as to overlap each other.

Then, after developing these electrostatic latent images, they are transferred onto transfer paper and fixed.

If you repeat this process 6 times, you will get 6 sheets of 9 manuscripts.
Copies are made on the same transfer paper, and six copies are better.

In the next process, only two originals are left on the automatic document feeder, so in the last process, the two originals are copied onto the same transfer paper, and thus the copying process: finish.

The following description will be given with reference to the drawings.

In Figure 1, reference numeral 10 indicates a drum-shaped photoreceptor. First, an embodiment of the present invention will be described with reference to Figures 3-1 to 3. The premise is that the length of the original LO, the length of the transfer paper, and the number of originals to be copied on the same paper n are that the person making the copy has udt the correct information in advance.Copying The magnification may be fixed (same magnification) or variable magnification.

For example, in the case of the same size, when copying an A4 original onto A6 transfer paper, the copying person recognizes n=24, and when copying two A4 originals at the same time on A31J-gal size transfer paper. The copyer knows that the copying magnification should be 0.71 when copying at the same time. Therefore, the person making the copy always specifies the correct information as LO,n as described above.

As shown in Figure 6, the process is as shown in Figure 6.

Begin by specifying LO,n. This designation is performed by designating predetermined information on the input device 14 shown in FIG. 1'1. When the copy magnification is variable,
At the same time, the copy magnification m is also specified. The input section of the input device 14 is provided on the operation panel of the copying machine. input to the input device 14 or LO.

n i';]: control@] is applied to the device 12.

j! is formed on the photoreceptor 10 according to the copying magnification m and LO. The length of each latent image is determined to be 82 m/LO. Of course, it must be thrown with L/ξ≧n.

Next, as shown in Figure 6 as ``Original Set'', a plurality of manuscripts (having the same length LO) are placed. That is, the automatic manuscript feeder xw is set up to place these manuscripts.

Then, start copying. 1 is a variable for counting the number of originals to be copied on the same transfer paper at the same time, and it changes from 1 to n+1.
Each time a latent image is formed, one is created.

First, it is determined whether or not there is a document in the automatic document feeder 16 (Figure 1). If there is a document, the first document is fed out and placed at a predetermined position on the document placement glass. be done. In Fig. 6, "Original Placement 1" indicates this type of operation.Of course, the automatic document feeder 16 is controlled by the controller 12&c.

Subsequently, 'exposure 1', that is, irradiation of the original optical image onto the photoreceptor 10 is performed. During this exposure, the photoreceptor 10 and the exposure device 18 are controlled by the control device 12.

That is, the exposure is performed using the slit M light system, and as shown in FIG. 2, the exposure start position A is determined in a solid manner with respect to the mounting position of the copying machine.

On the other hand, on the photoreceptor 10, a reference position B for forming an electrostatic latent image is provided.
is determined, and when the variable (2) is 1, the photoreceptor 1 is moved so that this reference position B coincides with the exposure start position A.
0 position is set, and while the photoreceptor 10 is rotated in the direction of the arrow, an electrostatic latent image is formed from the reference position B. As mentioned above, the length of the electrostatic latent image formed at this time is ξ
=m-LO.

Next, the variable is incremented by 1 to become I+1 (=2), and the first document is ejected from the document placement glass by the automatic document feeder 16K, and a new document is ejected.
A second document is placed on the photoreceptor 10, and an electrostatic latent image corresponding to the second document is formed.

At this time, the control device 12 controls the exposure position on the photoreceptor, and the second electrostatic latent image is formed adjacent to the first electrostatic latent image.

That is, in the memo IJ-20C (Fig. 1), the photoreceptor rotation angle θ (ξ) corresponding to the latent image length ξ is stored as a table.

The control device 12 extracts this photoconductor rotation angle θ(ξ) from the memory 20, and when the angle θ(ξ) of the photoconductor is 2, the exposure start position on the photoconductor is changed from the reference position B to θ(ξ)(I −
1) Position the photoreceptor 10 so that it is rotated by 1)? Set. In this way, the positions of the four elements on the photoreceptor are controlled for each document.

In other words, referring to Figure 2, when image exposure is performed using the second original @, the photoreceptor position indicated by the symbol X (separated by ξ from the reference position B) at the start of exposure is Exposure is performed in such a way that the number of units is placed at position A. The case of spear 2ia)';j, n: 3 is described, and the 66th spear is 1 kyō 1. Bureau: Shizuki Hiroshi 1, who is old by τλ,
From the Y position to the Z position [6 form, F, and is also formed. In other words, in the case of 1 light, the positive/con of the photoconductor is controlled so that the Y position and the A position are aligned. Exposure begins at the Y position and ends at the Z position.

Note that i! of the exposure position on the photoconductor! IJ supremacy is control''
The Aj device 12 controls a photoreceptor-driving servo machine ↑4 (not shown).

Now, when the same process is repeated and n static images are formed on the photoreceptor, the variation (2) is raised to n + 1.

Then, development is performed on these n electrostatic transfer images, and the resulting visible images are on the same transfer paper (transfer paper length L≧n
ξ) and fixed. Then, the transfer paper on which the visible image is fixed is discharged from the apparatus as a copy.

As long as there is a document to be sent in the document feeder 16, the above-described process is repeated. At this time, necessary steps such as cleaning are performed as appropriate.

When the process is repeated and there are no more originals on the automatic document feeder 16, it is determined whether the value of the odd man at that time is 1 or not.

When I=1, an electrostatic latent image is formed on the photoreceptor (・
Since there is no such thing, I just terminate the process. ■≠1
In this case, n/(≦n) Vc static latent images are formed on the photoreceptor, so these are developed, the visible images are transferred and fixed onto the same transfer paper, and then the transfer paper is is discharged and the process is terminated.

Note that development, transfer, fixing, cleaning, etc. are also controlled by the control device 12. As the control device 12, a CPU
Alternatively, a microcomputer is used.

Figure 4 shows another embodiment. The difference from the embodiment shown in Figure 1 is that the example shown in Figure 4 includes an arithmetic unit 22.

We will briefly explain two examples of carrying out the invention using the apparatus shown in Figure 4.The copying rate may be fixed at the same magnification or may be variable. , here Ree,
Generally, the case of variable temperature will be explained. Among the copying factors that can be changed in magnification, the one with the smallest magnification value is m (MI
N). If the copying rate is fixed at the same magnification,
In the following explanation, +h (MIN) may be set to 1.

Now, let's take a look at the five figures.

In this example, first input is JA414.

When LO,n is specified, the profit 1 device 12 calculates the maximum number N by the calculation device 22 according to the specified LO,n VC.

This maximum number N is specified or calculated as the maximum number of natural numbers not exceeding n when m (MIN) Simultaneously (・ζ
9 Give the maximum number of copies of the manuscript.

Next, the arithmetic unit 22 compares the magnitude relationship between the specified γ and the calculated N.

If n≦N, the designation of n is correct, and in that case, the copying process described in Figure 6 below is executed as is.

If n>N, the designation of n is incorrect, and the same transfer paper VC can only copy N sheets of originals. After that, the same process as in Fig. 16 is realized from the original shoulder cent onwards.

]・In the case of the method shown in Figure 6, after the maximum number N is calculated, n and N are compared, and when n≦N, the procedure is the same as in Figure 5.

If n>N, there is an error in the specification, so an error is displayed to that effect using an appropriate display means (not shown in Figure 4).

The person making the copy will be prompted by this error message.

Knowing that there is an error in the designated VCs of L○ and n, these are re-designated. This re-designation is repeated once until the designation is corrected.

In addition, in the case of n<N, if there is an optimum copying magnification other than m (MIN) and it is possible to use that copying magnification, the control device 12 automatically selects the optimum copying magnification. You can also do this.

In the case of the device example shown in FIG. 4, both the control device 12 and the arithmetic device 22 can be configured by a microcomputer.

(effect) As described above, according to the present invention, a novel copying method can be provided.

Since this copying method is configured as described above, the automatic document feeder feeds the document one sheet at a time, and
Multiple originals can be copied onto the same transfer paper, and when multiple originals are VC-copied onto the same transfer paper, the multiple originals can be copied as original Ia! There is no hassle of arranging them one by one on the equipment lath.
