Abstract

PURPOSE:To improve work efficiency in case of copying a book, etc. by sending out a copying end signal to a form gathering machine at the respective time points of the time point when copying of a picture of the first half of a picture of an original has been ended and the time point when copying of a picture of the latter half has been ended. CONSTITUTION:A copying machine 100 is provided with a form gathering machine (sorter) 200. At the time point t1 when copying of a page PG1 has been ended, a body control part 100a sends out a job end signal JE to a sorter control part 200a. As a result, the sorter control part 200a resets a selection of a pin to the first pin, and thereafter, the body control part 100a copies a page PG2. Subsequently, at the time point t2 when copying of the page PG2 has been ended, the body control part 100a sends out the job and signal FE to the sorter control part 200a again and resets a selection of the pin to the first pin. In this way, two pages can be copies continuously, and the work efficiency is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method of controlling a copying machine equipped with a paper collating device.

[Prior Art] For example, when creating materials for a conference, bound materials such as books and notebooks (hereinafter referred to as "books, etc.") are often copied.

In this type of copying, the desired page of a book, etc. is opened and positioned so that one page of the spread is copied on the contact glass of the copying machine, and when the copying of that page is finished, the other page of the spread is Position the page, make a copy, and repeat this process for each page. Alternatively, the original document is copied onto a double-sized copy sheet such as a book, and the resulting copy sheet is folded in half or cut into two to match the size of the original document.

Therefore, it takes a lot of effort to copy a large amount of copies, such as when copying multiple copies of a large number of pages.

It took a long time, and since each page had to be aligned many times, the burden on the operator was quite heavy.

In addition, in the case of the latter work, the size of the copied paper becomes quite large, making it inconvenient to handle.
In addition, the copy paper may be damaged due to improper handling.

Conventionally, copying machines have been put into use that copy images of two-page spreads of books, etc. onto both sides of a single sheet of copy paper.
Such a copying machine has the disadvantage that the image, which was originally a double-page spread, is copied onto both sides of a single copy sheet, making it difficult to see the single image.

Furthermore, since the paper collating device cannot be connected, there is also the problem that the work efficiency is poor when making multiple copies at once.

[Purpose] The present invention has been made in order to eliminate the drawbacks of the prior art described in (a). To provide a copying machine control method that realizes a copy mode in which each of the divided images is copied onto copy paper smaller in size than the original, and improves work efficiency when copying a large number of copies of books, etc. It is an object.

Both the main body control unit 100a and the sorter control unit 200a of the copying machine 100 are equipped with a microprocessor, a ROM (read-only memory) that stores control programs corresponding to each device, and a RAM (random access memory) that serves as a work area and the like. (memory) and input/output circuits corresponding to each device. Further, the main body control section 100a and the sorter control section 200a are connected via an interface 10, and signals are exchanged. Note that this interface 10 is configured using a photocoupler or the like.

FIG. 3 shows an example of an operation display section 100b for an operator to operate this copying machine 100, and this operation display section 100b is provided at an appropriate position on the - side of the copying machine 100.

In the figure, 131 is a plinky that starts copying;

It is a vessel.

136 is a stack key for setting the stack mode on the sorter 200, 137 is a sort key for setting the sorter 200 in sort 1 mode, and 138 is a page continuous copy key for setting the page continuous copy mode, and each mode is set. The corresponding light emitting diodes 139, 140° 141 light up.

Further, 143 is an interrupt key for setting the interrupt mode, 144
is the first cassette selection key that selects the upper cassette 107;
145 is a lower cassette selection key for selecting the lower cassette h108, and 147, 148, and 149 are light emitting diodes corresponding to each key.

The case where the sorter 200 sorts the 7-copy sheets copied in the page continuous copying mode using the above configuration will be described below.

First, the operation of copying machine 100 in page continuous copying mode will be described.

As shown in FIGS. 4(a) and 4(b), the optical system 10
To the home position HP corresponding to the scanning start position of 2,
Book BK so that the outer edge of the left page PCI matches
is placed on contact 1-glass 10IJ:. In page continuous copying mode, page PCI is copied onto copy paper PAL, and page PG2 is copied onto another copy paper PA2.

When copying page PCI onto copy paper PAI, copying machine 100 operates in the same way as when page PGI is the only original document being printed on contact glass 101.

When copying page PG2 onto copy paper PA2, the optical system 102 is operated to scan a document that is twice the size of the combined pages PGI and PG2, and the electrostatic latent image of the page PCI is transferred to the photoreceptor 103. Only the electrostatic latent image of the page PG2 is formed on the photoreceptor 8-103. Then, the feeding timing of the registration roller 111 is controlled so that the leading edge of the copy paper PA2 coincides with the leading edge of the image of the page PG2.

Note that the following methods are available for not forming an electrostatic latent image in the page PGI portion on the photoreceptor 103.

■ During the period when the optical system 102 moves from the home position HI' to the last end cp of the page PCI, the optical system 102
Do not turn on the built-in light source (not shown).

■ On the surface of the photoreceptor 103 corresponding to page PCI,
No charge is applied by the charger 104.

(2) The surface charge of the photoreceptor 103 corresponding to page PG1 is removed by the eraser 105.

Furthermore, the sending timing of the registration roller 11 when copying page PG2 is changed depending on the size of page PCI to prevent image shift.

In this case, the document size can be known from the selected state of the cassette.

Now, the operator sets book B on the contact glass 101, turns on the page continuous copying key 138 to set the page continuous copying mode, and turns on the sort key 137 to set the page sequential copying mode.
When the print key 131 is turned on after setting the mode and setting the number of copies by operating the numeric keypad 132, the main body control unit 100a outputs the copy cycle signal CC (fifth
(see figure (a)) and enters a copy cycle, and at the same time sends a sort mode set command to the sorter control unit 200a to set the sort mode in the sorter 200.

Then, first, the main body control unit 100a copies the page PGI by the number of sheets that have been printed and outputs it to the sorter 200. Sorter 200 sequentially accumulates copy sheets discharged from copying machine 100 in bins below bin 1 205-1.

At a time point L1 when copying the page PGI is finished, the main body control section 100a sends a job end signal JP to the sorter control section 200a. As a result, the sorter control unit 200a returns the bin selection to the first bin 205-1, and waits in this state for the next copy sheet to be ejected.

After that, the first main body control unit 100a copies the page PG2 as described above, and sequentially transfers the copy sheets to the sorter 20.
Eject to 0. The sorter 200 stores copy sheets discharged from the copying machine 100 in the same manner as described above into a first bin 205-1.
M sheets are stacked one by one into the lower bins.

At time t]2 when copying of page PG2 is finished, the main body control unit 100a again sends the job end signal JIE to the sorter control unit 200a, and selects the bin from the first bin 205.
Return to -1.

In this way, two pages of one double-page spread are sequentially copied and sorted by the sorter 200.

The operator then opens the desired page of the book nK, turns on the print key 131 again, and does this for all pages, thereby obtaining the desired number of copies of the desired portion of the book OK.

Also, when copying multiple originals of the same size, if you place two originals at a time on the contact glass and select page continuous copying mode, each original will be copied sequentially onto copy paper of the same size. Therefore, the trouble of copying work can be saved.

Note that even when the stack mode is selected, the job end signal is issued when each page is finished copying, just as when the saw 11-1 mode is selected, so the copy paper for each page is accumulated in each bin. Ru.

The operations of each device in other operation modes are the same as those of the conventional device, so the description thereof will be omitted.

[Effect] As explained above, according to the present invention, two-page spreads of books, etc.
Since pages can be continuously copied and sorted by a sorter, there is an advantage that work efficiency when copying books etc. is significantly improved.
