Description

How to Check Original Double Feeding in the All-in-One Printer

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method for checking a fax (Double Feeding) in a multi-function document or a multi-function document, in particular, in a fax machine having an ADF (ADF: Auto Document Feeder) function. The present invention relates to an original double-feeding checking method that enables a user to inform a user of a double-feeded original page by checking it if the original page is double-feeding or copying.

In general, an automatic document feeder (hereinafter referred to as ADF) is a device that is added to office equipment such as copiers, facsimiles, and multifunction machines, and inserts or removes an original for each store when the original is read for transmission or copying of the original. Even if you do not insert the entire document into the ADF, it is a device that can be read by automatically feeding the original in the order of the original.

The facsimile machine is an office automation device that performs data communication using a public line network.It is a scanner capable of reading internal documents, a printer capable of outputting data in text form, and sending and receiving data to and from a remote party. A device integrated with a communication means such as a telephone line to exchange documents.

There are two types of faxes for automatic feeding of several originals.

First, using a high-end stamp (Stamp),

Secondly, the number of manuscripts scanned and sent is printed and notified to the user.

However, the above-mentioned method of using the high-end stamp is a method in which an INK stamp is used to stamp the bottom of the original when the original page is scanned to notify the user that the page has been scanned.

When using this method, there is a factor of price increase of about $ 2-3 in constructing a stamp circuit, and a mark taken by a stamp is left on the scanned original, so that the user cannot know even if double feeding is applied when the original is resent. Becomes

Also, the number of scanned originals can be printed and notified to the user without additional hardware configuration, but it is not possible to check which pages are double-feeded. Therefore, the user has to check the other party and resend the fax originals. And discomfort followed.

Therefore, the present invention was made to solve the above-mentioned conventional inconveniences, and its object is to check if the original page is double-feeding when sending multiple fax documents in a facsimile or multifunction device with an ADF function and double-feed the user. By notifying the original page, the user can check the double-fed original page to the other party, eliminating the trouble of the user having to resend the double-fed original page, and also provide user convenience when sending multiple originals. It would be.

In order to achieve the above object, the present invention provides a method for checking a double-fed document page during the transmission of multiple documents in a facsimile or multifunction device

Setting at least two or more originals when transmitting the fax original, scanning the originals at the scanning position of the set originals, counting and storing the number of steps of the moving originals when the scanned originals are moved, until the completion of one page scanning; Obtaining a step number value for the next page after storing the step number value for the first page, and obtaining a difference value of the step number for the two pages, and converting the difference value of the step number for the two pages obtained above into a predetermined unit And comparing the set value with the set value, and retransmitting the double-feeding page having the set value or more when the step difference is equal to or greater than the set value and printing the retransmitted page.

Hereinafter, an embodiment of the present invention according to the accompanying drawings in detail as follows.

1 is a block diagram of a multifunction printer according to an embodiment of the present invention for checking double-feeding of a document during document transmission, a document loading unit 100 for transferring a fax document or a copy document, and a scanner for scanning a loaded document one by one 200, a memory 300 that stores counter values for each original page, and overall control of the facsimile system such as original read inspection, read control, image processing, print control, data bus control, counter values of original pages, and the like. It consists of a central processing unit 400 and a printer 500 for printing an original.

FIG. 2 is a flowchart according to the present invention, in which two or more originals are set when the originals are transmitted (S10), scanning the set originals at a scanning position (S20), and moving when the scanned originals move as shown in FIG. 2. Counting the number of steps of the document to be counted (S30), counting the counted document until the completion of one page scan (S40), and when the scanning of one page is completed, the counter value of the number of one-page moving staff is stored in the memory Step (S50), the step of determining the next page after storing the value of one page (S60), if there is a next page to return to the original scanning step (S20) counting the next page value to store the counted value in memory, If there is no next page, calculating a difference value between the number of two page steps (S70), converting the difference value between the number of two page steps obtained above in a predetermined unit and comparing it with a setting value (S80), A staff member of a car transmission double feeding page more than set value or more if the set value in the comparison, and consists of a step (S100) for printing a page is re-transmitted.

3 illustrates an example of a double-feeding page when a document is transmitted, and FIG. 4 illustrates an enlarged view of a double-feeding page.

5 is a counter value of each original page for storing in the memory, and FIG. 6 shows a printing format form diagram.

Referring to the effects of the present invention configured as described above are as follows.

The following two situations may occur when scanning multiple originals on a current facsimile machine or multifunction device.

One of them is when the sheets are not separated properly and the two sheets are fed continuously at a slight interval.

The other is that two or more pages are overlapping at all, which is called MULTI-FEEDING.

In both cases, the scanning does not work as you want.

The present invention is to solve the first double feeding.

Also, when you want to send or copy the scanned document to the other party by scanning multiple originals from the facsimile machine, in most cases, collect the originals of various types (e.g., one A4 size and another one). Scanning rarely occurs.

In the present invention, double feeding can be checked only in the case of one type of original.

In the case of various types of originals or multi-feedings, the present invention cannot be processed, and conventionally, the number of originals transmitted by scanning a plurality of originals is printed and notified to the user.

Now, a description will be given of a method for solving double feeding that occurs when scanning a type of original.

First, the document to be sent or copied is set to the document loading unit 100 having the ADF (Auto Document Feedinf) function (S10).

After the document is set, it is sensed by an original sensor (not shown in the figure) of the document loading unit 100.

Therefore, after the original is set to normal, the user can make a phone call to send the original, or make a delay transmission, or use the copy key to copy the original. It is started (S20).

In this manner, the scanner 200 scans one line at a time, and the original is moved by one step by controlling the motor (not shown) of the central processing unit 400. In the case of a normal fax, it moves by 1 / 7.7 mm.

When the scanning is started in this way, the counting of the number of staff moving by the counter in the central processing unit 400 starts (S30).

If the document is A4 size, the number of moving staff on one page is about 2287.

As such, the number of steps until the completion of one page scan is counted (S40), and the counter value for the counted one page is stored in the memory 300 (S50).

In this way, the counter value for one page is stored in the memory 300, and then the scanning is started if there is a next page (S60).

In this case, the scanning completion of one page is detected by the CPU 400.

In the same manner as described above, the number of moving steps is counted for each page and stored in the memory 300. When the scanning or transmission of all pages is completed, the CPU 400 counts a counter for each page stored in the memory 300. Compare the values (S70).

Then, the central processing unit 400 compares whether the difference between the two pages (pages 1 and 2) of the comparison is 13 mm or more in terms of mm (S80).

In this way, the central processing unit 400 continuously compares all pages (1 page) and then differs by more than 100 steps (based on 13mm: 1 / 7.7mm steps) compared to other pages (page 2) (N = N +1) determines that it is double-feeding, and then prints the N + 2 page S90 through the printer 500 in the format shown in FIG. 6 to inform the user.

For example, if a user wants to transmit 5 sheets, and 2 pages and 3 pages are double-feeding as shown in FIG. 3, the actual 5 sheets are to be transmitted. As a result, only 4 sheets are transmitted as shown in FIG.

That is, as shown in FIG. 5, since the counter value of the second page of the counter value is larger than 100 steps (based on 13 mm: 1 / 7.7 mm steps), the actual third page length is not transmitted.

That is, the central processing unit 400 compares the counted value of the two pages, and if there is a difference of more than 100 steps, it determines that the page having the larger value of the two is double fed and the message to the printer 500 in the format of FIG. 6. To print (S100).

In the present invention operated as described above, when a fax or multifunction fax machine transmits a plurality of fax originals, or a copy original page is double fed, the user checks this and informs the user of the double fed page. The user's convenience can be provided by eliminating the user's hassle to retransmit the double-feeding original page by checking with the other party.
