Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a copying machine, and particularly to a copying machine equipped with an automatic document feeder capable of feeding a document made of computer form paper.

(Prior art) In conventional copying machines, multiple originals are separated one by one, automatically conveyed onto a contact glass, temporarily stopped, and after exposing the original image, are conveyed from the contact glass. A device is known that is equipped with an automatic document feeder and improves operability when copying many documents in succession. Also, automatic document feeders are known that can feed documents made of computer-form paper.

In a copying machine equipped with an automatic document feeder capable of transporting such computer form paper, the folded computer form paper is placed on the document table, and the topmost page of the computer form paper is placed on the document table. All pages of computer form paper can be automatically copied by simply inserting it into the transport unit and pressing the copy start button.

[Problems to be Solved by the Invention] However, in conventional copying machines equipped with an automatic document feeder capable of transporting computer-form paper, costs increase and copying becomes difficult due to the reasons mentioned above. There was a problem that it was time consuming.

That is, when fishing on a boat, there are often pages in the middle of computer form paper that do not need to be copied. In such a case, in the conventional copying machine as described above, the following two methods can be considered.

One method is to copy all pages, including pages that do not require copying, and then remove the recording paper corresponding to the unnecessary pages. The other method is to stop the copying operation after copying up to the page immediately before the page that does not need to be copied, to maintain the continuous computer form paper, and to keep the page folded if the page that does not need to be copied is a collection. In this method, pages that do not need to be copied are manually sent to the ejection side, the combiator form paper is reset to a state where copies can be made from pages that need to be copied, and then the copying operation is started again. In the former method, unnecessary copying operations are performed, which increases costs and requires a long time to remove the recording paper. In addition, in the latter method, it is extremely troublesome to selectively send only pages that do not need to be copied, in order to prevent problems such as tearing the computer form paper or folding the paper at places other than the perforations. .

(Objective of the Invention) Therefore, the present invention reduces costs by making it possible to stop the copying operation while continuing to convey the computer form paper when a page that does not need to be copied is conveyed onto the contact glass. It also aims to reduce the effort involved in copying.

[Structure of the invention]

In order to achieve the above object, a copying machine according to the present invention includes a copying machine main body that has a contact glass and copies the original on the contact glass onto recording paper, and a computer form paper that is composed of a plurality of pages arranged in a row. an automatic document feeder having a document conveyance mechanism that conveys the document onto a contact glass, a detection means for detecting perforation of computer form paper conveyed by the document conveyance mechanism, and based on the detection result of the detection means, A control means for controlling the drive of a document transport mechanism to intermittently transport the computer form paper, and instructing a copying machine main body to perform a copying operation in accordance with the transport of the computer form paper, and forming the computer form paper. In a copying machine where a plurality of pages are made up of pages that require copying and pages that do not require copying, when the page that does not require copying is conveyed onto the contact glass, a copying unnecessary signal is inputted to notify the conveyance of the page that does not require copying, and the copying is performed. When an unnecessary page passes over the contact glass and a copy-required page is conveyed onto the contact glass, a signal input means is provided for inputting a copy-required signal that informs the conveyance of the copy-required page, and the signal input means is provided with a copy-required signal. When the necessary signal is input, the copying operation of the copying machine main body is stopped while the conveyance operation by the document conveyance mechanism is continued, and when the copy necessary signal is input to the signal input means, the conveyance operation by the document conveyance mechanism is continued. The computer is characterized in that the control means controls the driving of the document transport mechanism and also instructs the copying machine main body to perform the copying operation so that the copying machine main body starts the copying operation while the copying machine main body starts the copying operation. The control means may control the drive of the document conveyance mechanism so that the computer form paper is continuously conveyed by the document conveyance mechanism while the unnecessary pages of the form paper are conveyed over the contact glass. .

Hereinafter, the present invention will be specifically explained based on Examples.

1 to 5 are diagrams showing an embodiment of a copying machine according to the present invention.

First, the configuration will be explained.

In FIGS. 1 to 4, 1 is a copying machine body having a contact glass 2;
The above original is copied onto recording paper (not shown). 10 is an automatic document feeder, and the automatic document feeder 10 includes a document detection sensor 11, a perforation detection sensor 12, 13, a document leading edge sensor 14, a control section 15,

The drive control unit 17 controls the driving of the servo motor, clutch, solenoid, etc. of the document transport mechanism 19. That is, the control section 15 and the drive control section 1
7 controls the driving of the document transport mechanism 19 to intermittently transport the computer form paper P based on the detection results of the perforation detection sensors 12 and 13, and also controls the main body of the copying machine according to the transport of the computer form paper P. 1 constitutes a control means for instructing a copying operation. The plurality of pages constituting the computer form paper P are -
Since boat fishing often consists of pages that require copying and pages that do not require copying, the computer form paper P of this embodiment includes pages that do not require copying.

The document feed switch 18 is a switch operated by the operator when a page that does not need to be copied is drawn into the document transport mechanism 19 and when a page that needs to be copied following the page that does not need to be copied is drawn into the document transport mechanism 19. be. That is, the document feed switch 18 is activated when a page that does not require copying is conveyed onto the contact glass 2.
Input the copy unnecessary signal to notify the conveyance of the unnecessary copy page, and the unnecessary copy page will be placed on the contact glass 2.
When the page requiring copying is conveyed onto the contact glass 2 by passing through the contact glass 2, a signal input means is configured to input a copying necessary signal to notify the conveyance of the page requiring copying. The control unit 15 and the drive control unit 17 control the document feed switch 1
8 is operated by the operator to input a copy unnecessary signal, the copying operation of the copying machine body 1 is stopped while the document conveyance mechanism 19 continues the conveyance operation, and the document jump switch 18 is operated by the operator. When a copying necessary signal is inputted to the printer, the drive of the document transport mechanism 19 is controlled and the copy machine main body 1 starts the copying operation while the document transport mechanism 19 continues the transport operation. command. Furthermore, in this example,
While the pages of the computer form paper P that do not need to be copied are transported over the contact glass 2, the original transport mechanism 19
The control section 15 and the drive control section 17 control the driving of the document conveyance mechanism 19 so that the computer form paper P is conveyed in fast forward mode continuously rather than intermittently. - On the other hand, the control unit 15 calculates the number of perforations after the copy unnecessary signal is input to the document feed switch 18 and the first perforation gin of the unnecessary page is detected by the perforation detection sensor 1.
It has a counting function based on the detection signal from 2.13.

Here, the 11 feeding paths of the computer form paper P will be explained. As shown in FIG. 2, the computer form paper P is placed on the CF document tray 3 placed on the right side of the document transport mechanism 19, and is inserted into the document transport mechanism 19 via a sensor section 6, which will be described later. Ru.

The computer form sheets P are sequentially conveyed to predetermined positions on the contact glass 2 by the document conveyance mechanism 19.
After the copying process is performed by the copying machine main body 1, the paper changes direction downward after passing the document receiver 4, and finally reaches the discharged document storage box 5. The document detection sensor 11 and the perforation detection sensors 12 and 13 are arranged in the sensor section 6 as shown in FIG.
The document leading edge sensor 14 is arranged as shown in FIG. Also, Figure 3 shows computer form paper P.
The document is inserted into the paper feed slot with one end guided by the document side guide 7 and the other end guided by the sensor section 6. Note that the document side guide 7 and the sensor section 6 are configured to slide in opposite directions in synchronization with each other.

Next, the effect will be explained.

First, marks are placed on the backs of the first and last pages of consecutive pages that do not require copying in the computer form paper P, and the computer form paper P is placed on the CF document holder 3. Next, align the perforation position of the leading edge of the first sheet of computer form paper P with the document reference position on the contact glass 2, and set it, and move the document side guide 7 and sensor unit 6 to feed the computer form paper P. Adjust the paper condition and perforation position. Next, when the document leading edge sensor 4 detects the leading edge of the document, the control section 15 controls the drive control section 17 to prepare for feeding the document. At this time, the document detection sensor 11 and perforation detection sensors 12 and 13 of the sensor section 6 detect the state of each document. For example, the document detection sensor 11 detects the presence or absence of a document, in other words, whether one end of the document has reached the sensor section 6, and the perforation detection sensors 12 and 13 detect whether or not there is perforation in the document. Detect. The control unit 15 detects the perforation detection sensor 12 based on the detection signals from the document detection sensor 11, the perforation detection sensor 12, and the machine 3.
．． If a perforation is detected in step 13, it is determined that the computer form paper P has been inserted, the CF mode, that is, the transport mode for transporting the computer form paper P is selected, and the drive control unit 17 and the copying machine main body 1 are In addition, if the perforation detection sensor 12.13 does not detect a perforation, the document is determined to be a sheet document, and the 5ADF mode, that is, the mode for conveying the sheet document, is selected, and the drive control unit 17 and the copying machine main body 1 5ADF mode is notified to.

Next, when the operator presses a print key (not shown) on the copying machine main body 1, the drive control section 17 performs drive control of each section, and conveyance of the computer form paper P is started. Next, when the page that does not need to be copied is conveyed onto the contact glass 2, when the operator presses the document jump switch 18 using the mark on the back side of the computer form paper P as a guide, the copying machine continues to convey the document. The copying operation of main body 1 stops. Next, when the last page that does not need to be copied passes over the contact glass 2 and the page that needs to be copied is conveyed onto the contact glass, the operator presses the document feed switch 18 using the mark on the back side of the computer form paper P as a guide. When pressed, the copying operation of the copying machine main body l resumes while conveyance of the document continues. During the period from when the copying operation is stopped until it is restarted, that is, while pages that do not need to be copied pass over the contact glass, the transport mode of the computer form paper P changes from the intermittent CF mode to the fast forward mode, and the computer form paper P changes from the intermittent CF mode to the fast forward mode. P is fast forwarded. Furthermore, when the document feed switch 18 is operated for the first time, the control section 15 controls the perforation detection sensor 1.
2. The number of perforations is counted from the first perforation of the first unnecessary page to be copied based on the detection signal from step 13, and after the second operation of the document feed switch 18, the number of perforations corresponding to one page is counted. When the number N is an integer multiple, change from fast forward mode to C.
The copying operation is started upon moving to F mode.

Thereafter, the above-described operation is repeated every time there is a mark on the computer form paper P, that is, every time there is a page that does not require copying, until all pages of the computer form paper P are conveyed.

Note that some copying machines display the total number of documents conveyed on the display of the copying machine main body 1 or the automatic document feeder 10, and many computer form papers have page numbers added to them. When both conditions are met, there is no need to mark the page, and the operator memorizes or notes the start and end page numbers of pages that do not need to be copied, and presses the document jump switch while checking the page number on the display. Just press 18.

As described above, in this embodiment, by operating the document feed switch 18, while the unnecessary pages of the computer form paper P are being transported over the contact glass, the computer form [P(7)] continues to be transported. While
Since the copying operation of the copying machine main body 1 is stopped, the work of extracting copies of pages that do not need to be copied, unnecessary copying operations, or the troublesome work of resetting the computer form paper P, which were previously necessary, are all unnecessary. It is possible to reduce the cost and the effort required for copying. Note that when there is only one group of pages that do not need to be copied on the computer form paper P, the above-mentioned effect can of course be obtained in the cases shown in patterns B and C in FIG. The effect is great in such cases, and even more so when the group of pages that do not need to be copied is distributed over multiple locations.

In addition, pages that do not need to be copied are not transported intermittently,
Since the computer form paper P is conveyed by continuous rapid forwarding, the copying time of the computer form paper P can be shortened, and copy productivity can be improved.

〔effect〕

According to the present invention, while the unnecessary copy pages of the computer form paper are conveyed over the contact glass,
Since the copying operation of the copying machine itself is stopped while the computer form paper continues to be conveyed, there is no need to copy pages that do not need to be copied and wasteful copying operations that were previously required, or the troublesome reuse of computer form paper. All the setting work etc. can be made unnecessary, and the cost and effort of copying can be reduced.

Furthermore, if pages that do not need to be copied are conveyed continuously instead of being conveyed intermittently, copying time can be shortened and copy productivity can be improved.
