Abstract

PURPOSE:To fold a recording paper with both faces copied to a half size and to bind by changing an outputting sequence every page by a means for changing the sequence of a picture of an opening original on the read sheet every page and copying both faces of the opening original. CONSTITUTION:When a written page number is transmitted to a register 16 in a sequence suitable for the state of an original, a ROM15 receives it, transmits a leading address of a page to a counter 12 and an end address to a register 14 and a reading is started in a reading part 100. Namely, a left page A and a right page B of the first sheet and a left page C and a right page D of the second sheet are respectively written on page Nos.1-4 of a page memory 101 in a sequence of A, B, C, D. In a recording part 102, in order to record picture data, the sequence of the leading address and the end address set to the counter 12 and the register 14 is changed in a data reading. Namely, the reading is performed in the sequence of the page numbers 4, 1, 2, 3, and on the left page of the surface of the first sheet, D is recorded and copied, on the left page of back, B, and on the right page, C are recorded and copied. The same procedure is performed on the originals after the third sheet. Thereby, the recording paper with both faces copied is folded to a half and bound.

Description

DETAILED DESCRIPTION OF THE INVENTION [Summary] The present invention is a copying method in which the pages of a two-page spread document are replaced in a copying machine so that a book can be bound in the same page order as the original.

[Industrial application field]

The present invention relates to a double-sided copying method using a copying machine, and more particularly, to a copying method for double-sided copying of a two-page spread document.

[Conventional technology]

FIG. 7 shows a copying system of a conventional analog copying machine. As shown in FIG. 7, a conventional analog copying machine copies the two-page spread document shown in FIG.
As shown in Figure (b), single-sided copying became possible, and double-sided copying resulted in the result as shown in Figure 7 (c1), which had the disadvantage that the page order was not continuous when bound. , copying machines capable of digital processing have been put into practical use.

FIG. 8 shows the structure of a digital V copying machine. The original read by the reading unit is subjected to signal processing in the storage/control unit, and is recorded in the recording unit. Each part has a light receiving element.

It is equipped with a page memory, a control circuit, a laser unit, a photosensitive drum, a duplex copying mechanism, etc. A digital copying machine faithfully records and reproduces the original that it has read, and also uses digital I
By taking advantage of the digital format, you can perform intelligent functions such as enlarging, reducing, cropping, and masking.

However, even if double-sided copying is possible, when copying a two-page spread of a book, conventional copying methods do not produce the same page order as the original copy when the book is bound.

[Problem that the invention seeks to solve]

The purpose of the present invention is not only to record the original in the same order as it was read, but also to record each page in a predetermined order when copying a double-page spread, and to make double-sided copies so that the paper on which the double-page spread is recorded can be folded. To provide a method that allows a book to be folded and bound in the same page order as the original copy.

[Means for solving problems]

The present invention is a digital copying machine that has a function that allows duplex copying and a memory that stores two or more images, and that changes the output order for each page by changing the order of the images of the read spread document on a page-by-page basis. By making double-sided copies of the two-page spread image, the double-sided copies of the recording paper can be folded in half and bound into a book.

[Effect]

The page order changed by folding the copy paper is made to be the same as the original copy at the time of bookbinding by reversing the page order in the memory.

〔Example〕

FIG. 1 is a block diagram for implementing the invention.

First, the reading unit 100 reads a two-page spread document, and the image signal 1
Send. The image signal 1 is written in page memo IJ 101 page by page. On the other hand, the recording unit 102 reads out the image signal 2 page by page from the page memory 101 and copies it on both sides. Here, the output order switching unit 103 for each page
Copying is performed by controlling the write and read addresses of the page memory 101 and changing the read order for each page from the page memory 101.

The operation of the output order switching unit 103 for each page will be specifically explained below.

First, when a document is read in the reading section 100, the document size is specified in the ROM 15, and the document state and an access signal for the page memory 101 are specified in the control circuit 17. Here, the original size is A4. This is information such as BS. On the other hand, the document states are two types of states shown in FIGS. 2 and 3. That is, 1! shown in Figure 2! In the case b, all the information is necessary, and in the case of the third flash illustration, the first left half of the read double-page spread document is unnecessary. Further, the access signal of page memo +7101 is a signal that informs whether to write or read from the page memory 101. Since the document is now being read, the control circuit 17 reads the page memory 1.
It operates to write data to 01. In other words, write page numbers in registers (RF, C,
) Send to 16. The order of written page numbers must be changed depending on the state of the manuscript, and the details will be explained later. Then, the R5M15 receives the write number from the register (REG) 16, transmits the start address of the page to the counter (CNT) 12, and transmits the end address of the page to the register (REG) 14. That is, the ROM 15 records the start and end addresses of the page memory 101 suitable for various document sizes on a page-by-page basis, and a signal indicating the document size and which page of the page memo IJ 101 is accessed is specified. For example, the first address and the last address are sent. In this way, addresses are first set in the counter (CNT) 12 and the register (REG) 14. After that, when the reading section 100 starts reading, the multiplexer (MPX) 11 gives a clock for data writing to the counter (CNT) 12, the value of the counter (CNT) 12 increases, and according to the address, the page memo 9101 Data is written sequentially from the top address of the page. Then, one page of image data is written into the page memory 101 by repeating this process until the address comparator (COMP) 13 matches the end address set in the register (REG) 14. Furthermore, when the values match in the comparator (COMP) 13, the control circuit transmits the next writing page number to the register (REG) 16, and also sends the counter (CNT) to the register (REG) 16.
) Clear 12.

Then, according to the write page number of the register (REG) 16, the new start address and end address are displayed on the counter (CN
T) 12 and register (REG) 14, and the image data of another page is page memo! Written to J101.

On the other hand, in order to record image data in the recording unit 102, the address of the page memo IJ 101 is controlled in the same manner as in reading, and the data is read out. First, the multiplexer (MPX)
) 11, a clock for reading data is input to a counter (C
NT) 12. And counter (CNT) 1
Data is sequentially read from the first address of register (REG) 14 and comparator (COMP) 1.
By repeating step 3 until they match, image data for each page is read and recorded.

Here, in order to change the reading order from the page memory 101, the counter (CNT) + 2
It is necessary to change the order of the start address and end address set in the register (REG) 14. That is, the order of the read V (numbers) sent from the control circuit 17 to the register (REG) 16 must be different from the order of the write page numbers. varies depending on the condition of the document.

Therefore, the case of FIG. 2 will be explained first. Figure 2 shows a case where all the ↑d information read is required.

In other words, this is a case where two sheets of a double-page spread document (Iff, one sheet of paper is produced each time you take a double-page spread document).In this case, the double-page spread document is
The state is shown in figure (a). So first, the first left page (A) and right page (BL), the second left page (C), right page (D)
is page memory 1 in the order of (N, (Fl, (C1, ■))
01 page numbers (1) to (4), respectively.

The correspondence with this page number will be explained using FIG. 4. The images (A), (B), (C), (o) and the writing numbers correspond to the first image in FIG. 4(a). On the other hand, reading image data from page memo IJ 101 is as follows:
First, the image (1)) written on page number (4) is read out, and then the images (A), (B), ( C). That is, images (A), (B), (c)
, (DJ and readout page number correspond to the first page of Figure 4 (bl). Then, (D) is on the left page of the front of the first page, (3) is on the right page, and (3) is on the back left page. B).

C) is recorded on the right page. That is, the copy is made in the state shown in FIG. 2(b). Similarly, page numbers (11, (2), (3),
Write in the order of (4), (4), (1), (2)
, (3), double-sided copying is performed in the same manner for the second and subsequent sheets.

As a result, as shown in FIG. 2(c), the recording paper that has been copied on both sides can be folded in half and bound into a book.

On the other hand, as shown in FIG. 3, when the first left page is unnecessary, it is necessary to read three double-page spread documents to create the first recording sheet. At this time, the two-page spread manuscript is shown in Figure 3 (
The situation is a). First, the first sheet (A and B) and the second sheet (C and D) are written on page numbers (1) to (4) as in the case shown in FIG. 2 described above. The first left page (A) is not necessary for copying, and the third left page (E) is necessary.

Therefore, write (smell) on page number (5) of page memo + 7101, and write the third right page (F) on page number (1) where (~ is written. In other words, image (5) , (
B), (C), FD), (E), and (F) correspond to the written page numbers shown in the first page of FIG. 5(a). On the other hand, to read image data from the page memory 101, among the necessary information, the page number (5) on which (E), which is the data of the fourth page, is written is read out, and then the page number (2), (
3) Images (B) and (C) written in (4)
, (Read out DJ. That is, image (B), (C
), (D), (E) and the reading page numbers are shown in Figure 5 (
This corresponds to the first picture in b).

Then, ■) is recorded on the left page of the front of the first sheet, (B) is recorded on the right page, (C) is recorded on the back left page, and (D) is recorded on the right page. That is,
The copy is made in the state shown in FIG. 3(b). For copying the second and subsequent sheets, it is sufficient to read two sheets of a spread document at a time. For example, when the first copy is completed, there are 2 pages in the page memo I7101.
Image (F), which is the information necessary for copying the second sheet, has already been written. Therefore, data for the remaining three pages is sufficient. Therefore, the 4th sheet (G and H), the 5th sheet (I and J)
) on page numbers (2) to (5), and 4 pages of data (Fl, (G)) required for copying.

(6), (I) are read in the order of (I), F), (G), and (6). That is, page numbers (4), (1),
Read out in the order of (2) and (3). At this time, as shown in Figure 3 (
It is copied in the state of the second sheet in b). As described above, five pages of information, including one page of information necessary for the next copy, are written in the page memo 17101, and four pages of information necessary for the next copy are read out. Then, the page memory is read and written according to the correspondence between the image and the writing/reading page numbers shown in Fig. 5, and the read images of the full original are copied on both sides of the recording paper as shown in Fig. 3(c). can be folded in half and bound into a book.

becomes. As described above, in the present invention, five pages of image data are written to the page memo+7101, so the page memory 10
The capacity of 1 is IOMB.

FIG. 6 shows another embodiment of the invention.

In this figure, the same parts as those shown in FIG. 1 are given the same numbers.

In this embodiment, a compression/decompression section is added to the one shown in FIG. Pressure M? i part 201. Restoration unit 202. Starting address for each page RAM 203. A multiplexer 204 is added. The compression unit 201 compresses data, and the decompression unit 2
In 02, the data is restored every 2 pages in the optical head address RAM,
The multiplexer 204 receives data from the compression unit 201 and assigns a start address to each page, multiplexes the signals from the ROM 15 and the register 16, and sends the multiplexed signals to the RAM 203. As the compression method, for example, the MH or MR method used in facsimile machines is used. In this embodiment, the read information is compressed to about 1o by the compression unit 201 before being written to the memory, so
The memory capacity of each page is about 200 KB, which has the effect of significantly reducing the page memory capacity.

〔Effect of the invention〕

According to the present invention, since double-sided copies of a double-sided manuscript can be folded close together and bound, the number of copies is smaller than in the case of single-sided copies, and the effect is that it can be organized compactly.
