Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile apparatus, and more particularly to a facsimile apparatus having an automatic paper feeding function that can continuously electronically transmit a plurality of original documents.

In conventional facsimile machines with this type of automatic paper feeding function, the paper quality of the originals may be different, the stacked originals may be in close contact with each other, or the originals may have creases or other irregularities. Therefore, there is a possibility that malfunctions such as two-sheet feeding may occur.

Therefore, various methods have been proposed to prevent malfunctions such as double-sheet feeding.

For example, before starting communication, the number of originals to be transmitted is input into the facsimile transmitter in advance, and this input number is compared with the number of sheets actually received.
In order to let the operator of the facsimile transmitter/receiver detect an abnormality, a method was adopted in which an alarm or photoelectric display was used to alert the operator of the facsimile transmitter/receiver when the document that had been set in the facsimile transmitter had finished being electronically transmitted. However, even if warnings such as alarms and displays are generated, the operator must go to the location of the facsimile machine after detecting these warnings, and in this state, the operator of the facsimile transmitter can count the number of sheets actually received. The need arose.
Since the telephone line remains connected while the number of tickets is being checked, there is a drawback that telephone charges will be added to the telephone line.

Alternatively, there is a system that notifies the operator of double feeding, such as sending two sheets, after the wire transfer is completed and the telephone line is released. However, in this type of system, the operator has to call the same party again and resend the document, which is time consuming.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks, to make an operator aware of the occurrence of double feeding during document transmission, and to enable processing for double feeding during the transmission period.

In order to achieve the above-mentioned object, the present invention provides a facsimile device having a function of transmitting a plurality of original pages. A detection means to detect and count the number of originals to be actually transmitted, and when the last page of the original is detected by the detection means, the count value of the number of originals to be actually transmitted and the number inputted by the input means. A configuration is adopted that includes a comparison means for comparing the number of manuscripts, and a means for detecting double feeding of manuscripts according to the comparison result by the comparison means and notifying that double feeding has occurred during transmission of the final page of the manuscript. .

The details of the present invention will be explained below based on embodiments shown in the drawings.

FIG. 1 shows the transmission procedure in G mode according to CCITT Recommendation T.30. In FIG. 1, the left side of the figure shows the transmitter side, and the right side shows the receiver side, indicating that time flows from top to bottom.

First, when electronic transmission is performed, from the receiver side
CED (Called Station Identification) signal 13, NSF (Non-Standard Equipment Installation) signal 14 and DIS signal (Called station equipment
Digital identification signal indicating that it has CCITT function)
15 is sent out.

On the other hand, from the transmitter side, an NSS (non-standard device installation that responds to the NSF signal) signal 16 is sent out, followed by a DCS signal (digital command), a training signal 18, and a TCF signal (training check) 19.
is sent.

Following this, the receiver side sends out a CFR signal (confirmation of reception readiness) 20 and starts reception. Following the training signal 21, the transmitter side sends out a message 22, sends out an RTC (return to control) signal 23, and sends MPS (multipage) or EOM (multipage) depending on whether the transmitted original is a short page or multiple pages. Message end) or EOP (procedure end) signal 24 is sent. Also, from the receiver side, MCF (message confirmation)
After sending out the signal 25, if the signal 24 is MPS, it returns to the training signal 21 and repeats the subsequent steps. If the signal 24 is EOM, the process returns to the NSF signal 14 and repeats the following procedure. And finally, the DCN (disconnect command) signal 26 from the transmitter
is sent, all procedures are completed, and the line is disconnected.

In the present invention, it is assumed that signal processing is performed according to the procedure shown in FIG.

By the way, FIGS. 2A and 2B are block diagrams of the control circuits on the transmitter and receiver sides, respectively. In FIG. This circuit allows an operator to input the number of originals set in a paper feeder or the like.

The number of originals input to this circuit 1 is input to a control circuit 2 as an output 1a.

The reference numeral 3 is an MCF signal detection circuit, which indicates that all messages have been received and additional messages may continue. Its output 3a is input to an addition counter circuit 4, and is detected every time an MCF signal is received. The number of times a document is electronically transmitted to the transmitter is counted. The added result appears at the output 4a of the counter circuit 4 and is input to the control circuit 2.

Reference numeral 5 denotes a remaining document detection circuit, which detects that there is only one remaining document set in the automatic paper feeder, and outputs a high level to its output 5a when there is only one remaining document. The signal is input to the control circuit 2.

In addition, the control circuit 2 is configured so that the facsimile transmitter
After sending the RTC signal to the line, it receives the output 5a of the remaining document detection circuit 5, and if it is low level, it will generate a command pulse 51 to the output 40a, and if it is high level, it will generate the command pulse B52, and the MPS signal transmission circuit Enter 40. And MPS signal sending circuit 4
0 is due to the command pulse 51 from the control circuit 2.
Sends the MPS signal to the line.

In addition, the command pulse 5 sent out from the output 41a
2 is input to the EOM signal sending circuit 41, and the command pulse 52 sends out the EOM signal to the line.

Further, when the output signal 5a becomes high level, the control circuit 2 compares the output signals 4a and 1a and examines whether their values are equal. If the two values are not equal, output signals 6a and 7
Output high level to a and 8a, respectively NSS
The signal is inputted to a signal sending circuit 6, an alarm generation circuit 7, and a double feed occurrence display circuit 8.

In the initial state, output signals 6a, 7a, 8a
A low level is output for each. Control circuit 2 receives the NSF signal from the facsimile transmitter,
After receiving the DIS signal, a command pulse 50 is generated at the output 6b and input to the NSS signal sending circuit 6.

On the other hand, when the signal 6a is at a low level, the NSS signal sending circuit 6 sets the 33rd bit of the FIF (facsimile information field) of the NSS signal to a low level and sends out the NSS signal, and when the signal 6a is at a high level. In this case, the 33rd bit of FIF is set to high level and an NSS signal is sent. The alarm generating circuit 7 notifies the operator that an abnormality has occurred, and the double feed occurrence display circuit 8 notifies the operator that the content of the abnormality is double feeding. The alarm generation circuit 7 and double feed occurrence display circuit 8 are driven while the last document is being electronically transferred.

On the other hand, FIG. 2B is a block diagram showing the control circuit on the receiving side. In the same figure, the reference numeral 9 is an NSS signal detection circuit, and its signal 9a is input to the control circuit 10. FIF 33
Contains information about bits.

When the signal 9a becomes high level, the control circuit 10 changes the outputs 11a and 12a from low level to high level, and the alarm generation circuit 1
1 and double feed display generation circuit 12 are activated.

Next, specific control of the control circuit shown in FIGS. 2A and 2B will be explained with reference to the flowcharts shown in FIGS. 3A and 3B.

FIG. 3A is a flowchart illustrating the control operation on the transmitting side. First, in step 27, it is determined whether the output signal 5a of the remaining document detection circuit 5 is at a high level. If the signal 5a is at a low level, this judgment operation is repeated, and if the signal 5a is at a high level, the process proceeds to step 28, where the control circuit 2 takes in the output 1a of the transmission document number setting circuit 1, and then the addition counter circuit 4. The output 4a is accepted (step 29), and then, in step 30, the signals 1a and 4a are compared to determine whether they are equal.

If the content of signal 1a and the content of signal 4a are equal, the process proceeds to step 60, which will be described later.

If signals 1a and 4a are not equal, step
At 31, output high level to signal 6a,
It notifies the receiver side via the NSS signal sending circuit 6 that double feeding has occurred, and also sends signals 7a and 8a.
is set to a high level, the alarm generation circuit 7 and double feed occurrence display circuit 8 are activated, a warning is generated, a double feed occurrence display is performed, and the operator at the facsimile transmitter is called. This is steps 32 and 33.

The process then proceeds to step 60, where it is determined whether or not the NSF and DIS signals from the facsimile receiver have been received. If received, the control circuit 2 generates a support pulse 50 at the output 6b, and the NSS signal sending circuit 6
The NSS signal is sent via the .

On the other hand, if it is determined in step 60 that the NSF and DIS signals have not been received, it is determined in step 62 whether or not the transmitter has sent an RTC signal to the line.
Back to 60.

If it is determined in step 62 that the RTC signal has been sent, the process advances to step 63 and the remaining 1 document is
It is determined whether or not the output signal 5a of the sheet detection circuit 5 is at a high level. If it is determined that it is at a high level, that is, there is only one sheet remaining, the process proceeds to step 65, and a support pulse 52 is generated at the output 41a. , the EOM signal is sent to the line via the EOM signal sending circuit 41, and the process returns to step 60.

If it is determined in step 63 that the output signal 5a is at a low level, the process proceeds to step 64, in which a support pulse 51 is generated in the signal 40a,
The MPS signal is sent to the line via the MPS signal sending circuit 40 and the process returns to step 60.

On the other hand, FIG. 3B is a flowchart explaining the control operation on the receiving side.
The output 9a of the NSS signal detection circuit 9 is at high level,
That is, it is determined whether double feeding has occurred. If the level is not high, this judgment operation is repeated,
If the level is high, the process proceeds to step 35, where a high level is outputted to the output signal 11a, and then a high level is outputted to the signal 12a. This is the step
35 and 36 movements. When the signals 11a and 12a become high level, the alarm generating circuit 11 and the double feed occurrence display circuit 12 are activated to generate an alarm, display a double feed, and call the operator on the receiver side.

As described above, the system uses a configuration that warns of double feeding or other erroneous feeding while the last page of the document is being electronically sent, so that the last page of the document is not received. During the communication, abnormalities can be detected, and there is no need to check for abnormalities based on wasteful addition of call charges as in the past, and the addition of call charges can be eliminated or significantly reduced. Please note that the check for misfeeds and double feeds is not performed when there is only one sheet left;
This may be performed when a predetermined number of sheets remain.

In the above-mentioned embodiment, an example was shown in which the number of originals to be sent electronically is input into the facsimile transmitter before transmission starts.
It can also be included in the FIF of the NSS signal. If such a configuration is adopted, the facsimile receiver side receives the NSS signal and displays this information, allowing the operator at the receiver side to know what picture manuscript will be sent electronically. If the operator on the receiver side checks the number of documents received, it is possible to detect whether double feeding has occurred.

Further, in the above embodiment, electric transmission in the G mode is considered, but when considering electric transmission in the G mode, the electric transmission time for one document is about 3 minutes.
In the case of electronic transmission in G mode, when double feeding occurs, an alarm is generated from the moment the last document starts to be electronically transmitted, and when the double feeding occurrence is displayed, an operator is called. will be a little premature.

Therefore, in all modes of electronic transmission, when double feeding is performed, it is possible to generate an alarm and display the double feeding after a predetermined period of time has elapsed after the last document begins to be electronically transmitted, to avoid calling the operator. You can avoid wasting time by doing it properly. Specifically, the control flow of the control circuits 2 and 10 may be changed. In other words, on the transmitter side, between steps 31 and 32, it is sufficient to add a step to ``wait for a predetermined time'', and on the receiver side, between steps 34 and 35, a step to ``wait for a predetermined time'' may be added. All you have to do is do it.

As is clear from the above description, according to the present invention, in a facsimile apparatus having a function of transmitting a plurality of original pages, there is provided an input means for inputting the number of original pages to be transmitted before starting transmission, and an input means for inputting the number of original pages to be transmitted before starting transmission. A detection means to detect and count the number of originals to be actually transmitted, and when the last page of the original is detected by the detection means, the count value of the number of originals to be actually transmitted and the number inputted by the input means. The present invention adopts a configuration having a comparison means for comparing the number of originals, and a means for detecting double feeding of originals according to the comparison result by the comparison means and notifying that double feeding has occurred during transmission of the final page of the original. Therefore, the operator can arrive at the installation location of the facsimile machine while the remaining documents are being electronically transmitted, look at the display section of the facsimile machine, and recognize that double feeding has occurred. Therefore,
During the transmission period, it is possible to process double deliveries, eliminating the need to make phone calls again. Further, it is possible to prevent the telephone line from being held for a long time and unnecessary call charges being added.
