Abstract

PURPOSE:To prevent omission of transmitted original due to double field by providing mark sheets in front and rear of a transmitted original and comparing the number of sheets of actually read original and the number of sheets of original written in the mark sheets. CONSTITUTION:Mark sheets in which information that indicates at least the number of sheets of original is written are inserted in front and rear of the original. Insertion of the first and last mark sheets of the original to be read is detected by a sheet detecting circuit. Picture data on the original read between the two mark sheets are stored temporarily in a memory device 33, and the number of sheets of read paper is counted by a paper counting section 34. Counted number of sheets of paper and information of number of sheets of the original written in the mark sheets are compared 35 by the counting section 34. Consequently, the existence of the two mark sheets and reading of the original corresponding to the number of sheets written in the mark sheets are confirmed, and stored picture data stored in the device 33 are detected 36.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to a facsimile transmission system, and more particularly to a facsimile transmission system suitable for preventing reading errors when reading a transmission document.

(bl Technology background) Due to improvements in the automatic paper feeder that pulls in originals to be sent, facsimile machines have recently seen a significant increase in equipment defects in the sending system (reading part), such as double feeding (two-sheet feeding) of sending originals and document jams. However, this does not mean that such equipment problems in the transmission system have completely disappeared, and various countermeasures have been devised to deal with them. A method has been put into practical use in which the equipment emits an alarm sound to indicate an abnormality to the operator.

(C1 Problems with Prior Art) However, if a document to be transmitted is not sent due to double feed, there is no communication problem, and the device judges as if it were operating normally.

Therefore, the operator is not left with any information that double feeding has occurred, so it is determined that the operation is normal. For this reason, it was only when the receiving side looked at the received document that it became clear that there was a missing document in the transmitted document. As described above, in the past, there was no way to deal with document reading errors caused by double feeding during document reading.

(d+ Purpose of the Invention) An object of the present invention is to eliminate the above-mentioned drawbacks of the conventional art by eliminating reading errors caused by double feeding of originals that occur in the reading mechanism section (automatic paper feeding section), in other words, the problem of reading errors caused by double feeding of originals that occur in the reading mechanism section (automatic paper feeding section) To provide a facsimile transmission method that can prevent omissions.

(el) Structure of the Invention In order to achieve the above object, in the present invention, mark sheets such as OMR sheets used to specify the destination of the transmitted document are added to the front and back of the document, so to speak, the document is created using mark sheets. It is configured to check double feed of originals using the sand-inch method.Then, the number of originals is written on the mark sheet, and the number of originals actually read and the number of sheets written on the mark sheet are recorded. By comparing the information, it is possible to confirm the presence or absence of double feed.

Hereinafter, the present invention will be explained in detail using Examples.

(f) Embodiment of the Invention FIG. 1 is a diagram showing an example of the configuration of a facsimile transmission/reception system to which the present invention is applied. The system shown in the figure is

FIG. 4 is a diagram showing an example of a mark sheet (OMR sheet) used in this embodiment. As shown in the figure (this OMR
The sheet has a notch PK so that the transmitter (reader 14) can identify that this sheet is an OMR sheet. Furthermore, there are areas MEO, MEI, where marks are written for the operator to specify the transmission status, number of originals, destination, etc.
ME2゜MB3. − will be provided. Also, M r =
M□h is a timing mark for indicating the position of these mark areas MIEI, and area M□h is used as an identification for OMR sorting together with the notch PK. In this example,
Eight mark areas are provided between each timing mark M, to Mq. In other words, each mark area can be converted into 8-bit control information. Furthermore, in this embodiment, this OMR sheet is inserted above and below (front and back) of a unit document. Then, the sheet placed at the top of the manuscript is the star 1-OMR sheet (hereinafter referred to as S-OMR).
The sheet inserted at the end of the original is called the end OMR sheet (hereinafter referred to as the E-OMR sheet).
A mark area for specifying the type of these OMR sheets is also provided. In FIG. 4, the OM Rfi type is an S-OMR sheet, the status is priority, the number of original sheets (excluding both OMR sheets) is 15, and the destinations are A and C.

An example of marking when - is shown.

Also, the same mark information is written on the S-OMR and E-OMR sheets for the same original. Therefore, if the operator accurately marks both sheets, the same mark information will be written in all mark areas except the OMR type mark area.

The operation when transmitting a document using these OMR sheets will be described below with reference to flowchart 10 in FIG. 5 and an explanatory diagram in FIG. 6.

As shown in FIG.
(not shown), a plurality of documents sandwiched between two OMR sheets are set. Then, by an automatic paper feed (feed>ta mechanism (not shown)), the manuscript paper including the OMR sheet is fed out one by one, and the image is read by the reading unit 14.

When reading the original, the first paper fed is OM.
Determine whether it is an R seat or not. The presence of the OMR sheet can be confirmed by detecting the notch PK of the OMR sheet by the OMR detection section 15. At the same time, by looking at the image data obtained by the reading section 14,
The existence is confirmed by detecting the presence or absence of a pattern of timing marks M, -M1 attached to the topmost part (MEO) of the R sheet. It should be noted that the image data area 12a of the memory 12 has a capacity to store image data of at least one original document obtained by the reading section 14, for example.

Upon detection of the OMR sheet, the OMR detection section 15 activates the encoding section 16, feeds it from the MEO to the MEI area, and reads only the MEI area.

The image data thus read is encoded into the following M
Repeat this in order to feed up to the B2 area.

As a result, each mark area MV? of the OMR sheet? , I

or directly to the control unit 11, and sequentially sent to the converter TA 3 via the modem. on the other hand,
If the original scanned first is not an OMR sheet, the OMR
The detection unit 15 writes the error information in the error area in the memory 12 and notifies the control unit 11 to that effect. Thereby, the control section 11 reads the contents of the error area, displays it on the panel section 1, and notifies the operator. Then, reading of subsequent documents is stopped.

The encoded information on the OMR sheet is converted using a 30-line fa converter.
memory 3 via l+ 171S 32 and main control unit 31
3. This memory 33 has an area capable of storing all the code information of OMR files 1 to 1 sent from the facsimile transmitter 1 and image data.

Furthermore, an area 33a for identification information ID of the transmitter 1 and a document page counter 33b are provided corresponding to the read data of one document. This page counter 33b is incremented by the arrival of a page end signal included in the transmission/reception procedure with the transmitter 1.

In the storage exchange 3, first the OMR sent from the transmitter 1
From the sheet code information, the OMR sheet is S-OM
It is determined whether the sheet is an R sheet or not.

That is, OMR type mark information shown in FIG.
The comparison unit 35 checks. If it is detected through this check that code information other than the S-OMR sheet has been sent, the comparison section 35 notifies the main control section 31 of an error detection.

In response to this error notification, the main control unit 31 notifies the transmitter that sent this code information of the error, and stops the subsequent data reception operation. This error notification causes an operator error to be displayed on the panel *+Xt 7 of the transmitter 1. Needless to say, the reading operation of the transmitter 1 also stops.

If the code information of the S-OMR sheet is sent first, the transmitter 1 continues reading and sending out the image data of the original. and the monarchy tartars
3t counts and amplifies the page counter 33b each time one page of image data transmission/reception is completed, as described above. Thereafter, when the reading of the original sheet is completed, the code information of the next OMR sheets 1 to 1 is transmitted from the transmitter 1. Based on this code information, the B
- Confirmation of OMR sheet is performed. If this code information is different from the E-OMR, an error notification will be sent to the transmitter 1 in the same manner as described above.

When it is confirmed that the E-OMR sheet is code 1 green report, the comparing section 35 starts the sheet number determining section 34. Then, the number of originals included in the code information is compared with the count value of the page counter 33b on the memory 33. Then, it is checked whether the number of original sheets read (sent) is the same as the number specified on the OMR sheet. Furthermore, the 1 comparison unit 35 compares the received S-OMR and IE-OMR.
Excluding the OMR type mark area in the code information of each sheet, compare the code information of other mark areas to check whether they completely match.

If the results of the checks by the number checking section 34 and the comparing section 35 are correct, the transmitting section 36 will send the image data to the receiver 4 corresponding to the destination included in the image.

As described above, in this embodiment, the S-OMR sheet and the E-O
The configuration is such that the document is transmitted while being sandwiched between MR sheets (Fig. 6). Therefore, when sheets #2 and #3 in the document 1 shown in No. 6-1 are double fed, this double feed can be completely detected by the above-mentioned sheet number checking function.

Furthermore, if the E-OMR sheet is fed together with the previous original (original #4 and 1-?, -0MR of original I in Figure 6) (double feed), then When a certain document is read, it becomes the S-OMR (S-OMR with original f height 2) sheet of the next transmitted document. At this time, (S-OMR4
- Transmission original 10E-OMR), the form of the assembly operation is disrupted, so the device determines this as an error and stops the operation. Also, together with the E-OMR sheet, the S-OM of the next manuscript
If the R sheet is double fed (E of original 1)
- When the OMR sheet and the S-OMR sheet of original 2 are double fed), the previous sent original 1 will be fed if the contents of the S-〇MR sheet and the E-OMR sheet match (however,
Except for the type determination area, the device is accepted as a royal palace (manuscript 1 is OK). However, since the next S-OMR sheet does not exist due to double feeding, the transmitted document becomes the first sheet, and the apparatus can determine that there is an error without S-OMR.

Furthermore, if the marking area of the OMR sheet is dirty, or if the device reads the marked area even though the marking area has been erased, the document will be sent to the wrong recipient. In order to prevent this, the original to be sent is sand-inched between the S-OMR sheet and the E-OMR sheet, and the device reads the S-OMR sheet and the E-OMR sheet.
A method is adopted in which the contents of the OMR sheet are checked and if they match, it is considered good. In this way, the operator does not have to worry too much about the aforementioned ○MR sheet being dirty or not being completely erased. Furthermore, the number of erroneous transmissions of OMR sheets 1 to 1 can be significantly reduced by checking both OMR sheets.

As described above, in this embodiment, by using the OMR sheet sandwich method, double fields can be checked, there will be no erroneous transmission, and documents will be sent more reliably each time.

In the embodiment, the number of sheets and the OMR sheet are checked using a storage type exchanger, but even if these checking functions are provided in a single facsimile machine,
Of course, the present invention is applicable.

(gl) Effects of the Invention As described above, according to the present invention, the double feed that occurs in the reading example can be detected without exception on the sending side, and the sending of image data with document omissions can be prevented in advance.
