Abstract

PURPOSE:To eliminate misoperation by starting a 2nd copying operation automatically when detecting a paper refeed cassette being loaded on the paper feed part of a copying machine main body after a 1st copying operation when the copying operation is carried out in double-face copying mode. CONSTITUTION:When a copy is taken in double-face copying mode by using a paper refeeding device 130, a B-side copying signal is reset to '0' and an A-side copying signal is set to '1' after the 1st copying operation wherein copying paper is stored in the paper refeed cassette 150; and then preparations for the copying of a book A side are made. When the 2nd copy is taken, it is judged from an off signal from a paper refeed cassette detection sensor Se10 that the paper refeed cassette 150 is demounted from the paper refeeding device main body 131 and mounted on the paper feeding part of the copying machine main body 1, and a copy start flag is set to '1'. Then, the 2nd copying operation is double-face copying mode is started. Consequently, the operator's trouble in operation is eliminated and misoperation is precluded, so that the handling is improved.

Description

[Detailed Description of the Invention] The present invention is directed to a copying machine, in particular, to a copying machine that allows copy paper discharged from the copying machine main body to be re-fed from the paper feed section of the copying machine main body once it has been received. The present invention relates to a copying machine equipped with a paper refeeding device.

Prior art and its problems In general, in order to perform double-sided copying or composite copying in a copying machine, it is necessary to feed the copy paper again after the first copy has been made, and various paper refeeding devices have been proposed for this purpose. There is.

For example, JP-A-49-63441, JP-A-56-
Publication No. 95264 discloses that in order to make double-sided copying possible with an hour wheel operation, in a copying machine equipped with a U-turn path type paper path, a cassette installed in the paper ejection section is connected to the paper ejection section and the paper feed section. When copying to the front side, it is moved to the paper ejecting section and the copy paper is picked up once, and when copying to the back side, it is moved to the paper feed section and the receiver re-feeds the copy paper that was picked up. A paper refeeding device is disclosed.

Furthermore, Japanese Patent Application Laid-Open No. 58-134659 discloses that in a copying machine equipped with a straight bus-type paper passage, a sheet storage cassette having a sheet storage opening and a sheet feeding opening is connected to a sheet ejection section and a sheet feeding section. A paper refeeding device is disclosed that can be attached to and detached from the paper section by reversing the front and back sides.

However, in each of the paper refeeding devices described above, since the cassette itself is moved from the paper ejection section to the paper feed section, it is necessary to provide a separate paper ejection tray in the paper ejection section when back side copying is performed, and each cassette is moved from the paper ejection section to the paper feed section. The problem is that it is impossible to install it as an option in existing copying machines that do not have a paper refeeding device.

Therefore, the present applicant has already developed a paper refeeding device main body, which is equipped with a paper ejection tray and a paper refeed cassette that can also be attached to and detached from the paper feed section of the copying machine main body, to be attached to the paper ejection section of the copying machine. (Japanese Patent Application No. 61-18501).

Incidentally, in recent years, copying machines have been provided that have a book copy function that copies both facing pages of a book manuscript by dividing them page by page, and the above-mentioned paper refeeding device is applied to such copying machines. It is possible that

Normally, if a copying machine has a built-in automatic duplex copying machine, the copying machine itself automatically prepares for paper refeeding (second copying), so in "book duplex copy mode"
After the first copying is completed, the second copying operation can be started after waiting for the preparation for paper refeeding to be completed.

However, in the above-mentioned paper refeeding device, after the first copying is completed, the operator must remove the paper refeeding cassette from the paper refeeding device and attach it to the paper feeding section of the main body of the copying machine. Therefore, unless the copying machine itself is linked to such operations, the operator would have to input into the copying machine that this is the second copy, and input the start of document feeding, which would be cumbersome. In addition, there is a risk that an operational error may occur.

In order to solve the above problems, the copying machine according to the present invention has the following features: (a) A copying machine equipped with a book copy function that divides both facing pages of a book manuscript and copies them page by page. (b) a paper refeeding cassette that is removable from the paper refeeding device main body and also removable from the paper feeding section of the copying machine main body; a paper refeeding device ζ that can be installed in the paper ejecting section; (e) means for detecting that the paper refeeding cassette is installed in the paper feeding section of the main body of the copying machine; and (d) a means for activating the book copy function. When copying in double-sided copy mode, after the first copying in which copy paper is stored in the paper refeed cassette is completed, the detection means detects that the paper refeed cassette is completely installed in the paper feed section of the main body of the copying machine. The present invention is characterized by comprising a control means for automatically starting a second copying operation when the occurrence of the copying operation is completely detected.

In the composition of New Year-Monday or more, Bu 7 Cucobee 41! function and use the paper refeeding device to enter duplex copy mode, i.e.
When copying is performed in the book double-sided copy mode, the second copying operation can only be started after the first copying is completed and the paper refeeding cassette is attached to the paper feeding section of the copying machine main body. This eliminates the need for the operator to input information about the second copying process and the operation of the folding paper, thereby preventing operational errors.

A binding margin (e) of a specified width can be provided on the right side of the copy paper. If there is no margin in the manuscript, providing a binding margin will make it easier to bind the copies.

In this embodiment, two modes are provided. In the first mode, the image is simply transferred by the entire binding margin (see (A) in FIG. 10). In this mode, if the protruding portion of the document (d) is not a margin, image loss occurs. In the second mode, in order to eliminate image loss, the reduction rate [(paper length - binding allowance)/paper length] is calculated from the width of the copy paper (paper length) and the binding allowance, and the reduction rate is automatically calculated. Determine the copy magnification.

[k, Control procedure, FIGS. 24 to 83 (k-1, Control of copying machine main body) FIG. 24 shows the main routine (CPUI) for controlling the copying machine main body <1).

When (CP[J1') is reset and the program starts, first, in step (Sl), (RAM
clear, initialize various registers, and make initial settings to put each device into its initial mode. Next, in step (S2), an internal timer of (CPUI) is started. This internal timer determines the time required for one routine of this main routine, and its value is set in advance in steps (
SL).

Next, each subroutine shown in steps (S3) to (513) is sequentially called, and when the processing of all subroutines is completed, communication with other (CPU2) etc. is performed in step (514), and step (515) After waiting for the internal timer to end, the process returns to step (S2). The time length of one routine is used to count the various timers that appear in each subroutine.

FIG. 25 shows a subroutine for processing using a manual feed tray that can be executed in step (S3) of the main routine.

First, in step (520), it is determined whether the manual feed tray detection switch (SW9) is on-edge or not. If it is on-edge, that is, when the manual feed tray (36) is opened,
In step (521'), the manual copy display LED (23

Determine whether E D (264> is on or not. If it is turned on, a subroutine that processes the introduction of binding margin is called in step <524>. In other words, "binding margin + automatic reduction mode" refers to the length of the paper. This is a mode that automatically calculates the reduction rate from the binding margin, and since it is not known what size (length) of paper can be inserted in manual copying, the binding margin + automatic reduction mode is automatically canceled.

Next, in step <525), it is determined whether the book copy mode selection display LED (265) is on, that is, whether the book copy mode is on or not. If it is on, the manual copy size is also set. I can't do a book scan because I don't know. Therefore, step (5)
At step 26), the display LED is turned off, and at step (527), the book A side signal (265) and the book B side signal are reset to "rO", and the book copy mode is automatically exited.

Next, when it is detected in step (528> that the manual feed tray detection switch <5W9) is on, that is, that the manual feed tray (36) is closed, the manual feed copy display LED (232) is turned off. At the same time, in step (530), “

In step 4), the copy magnification is restored to the original magnification (before automatic reduction), in step (545), the magnification is displayed, and in step (separate 6), the magnification is transmitted to (CPU 2).

This is because the copy magnification, which was determined by the vapor length and binding position of the selected cassette before the selected cassette was pulled out, can no longer be calculated by pulling out the cassette, so the copy magnification is automatically returned to the original magnification. .

Next, when the new insertion of the upper cassette or lower cassette is confirmed in steps (547) and (549), the paper feed slot (20) and (
