Abstract

PURPOSE:To cut off a roll recording paper easily, by transmitting a marker signal after picture information is finished, and making the discrimination of the boundary between originals easy. CONSTITUTION:When the reading of the original is finished and picture information is finished for transmission, a reading and encoding section 7' outputs a marker start signal to an output line 7'-b accordingly. A marker signal generating circuit 23 receives this start signal, generates a marker picture signal and transmits it. The marker picture signal is recorded at the reception side and displayed as broken line pattern C for one or several lines' share, allowing to cut off the paper along the lines.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile device, and more particularly to a facsimile device that sequentially reads and scans a document and sends out image information obtained as an image signal.

Such a facsimile machine has a configuration as shown in FIG. Generally, facsimile machines are equipped with G [ThG1. G
Standards for 111 aircraft have been determined.

Although the explanations below are valid for all standards,
Here, the standard for one GII aircraft will be explained as an example.

In FIG. 1, a transmission document 1 is driven in the direction of an arrow by a drive device (not shown), and an image is formed on a reading and encoding section 7 by an optical system 5 including a lens. This reading and encoding unit 7 converts the optical information of the original into an electrical signal using a photoelectric conversion element such as a CCD, and then performs compression processing such as band compression encoding, and then converts it into a digital signal via a signal line 7.
-a and input to the modulator 9. A sensor 3 for detecting the end of the document is also provided, and a signal from this sensor appears on an output line 3-a and is input to the document detection circuit 11, and the output line 11-a is connected to the reading and encoding section 7.
is input. The reading and encoding section 7 sends a signal to the output line 7-a after completing the transmission of all the image information of one document.
It is configured to output a 'tTc signal (control return signal). The modulator 9 performs 8-phase differential phase modulation on the signal input from the signal line 7-a, and applies appropriate band limit? The applied modulated signal is output to the signal line 9-a.

Further, the signal from the reading and encoding section 7 is inputted to the timer circuit 17 and the procedure signal generation circuit 15 via the signal line 7-b to control them. The procedure signal generation circuit 15 generates various binary signals necessary for transmission and reception, and here, for the sake of simplicity, it is configured to transmit, for example, a ROM signal (message end signal) following the image signal and RTC signal. ing. This procedure signal is inputted to the modulator 13 via the signal line 15-a, where it undergoes frequency modulation specified for the procedure signal of the G11l facsimile machine and outputs it to the signal line 13-a. Also, the timer circuit 17 is connected to the signal line 1.
The switch circuit 19 is controlled via the signal line 9-a.
AS 13-a is connected to any one of the signal lines 19-a and sends out one image number and a procedure signal to a line 33 via a network control unit (hereinafter referred to as NCU) 21. In addition to facsimile signals, the NCU 21 sends signals from the telephone 31 to the line 33.
It can be switched so that it can also be sent.

In such a configuration, when the document 1 is scanned and the trailing edge of the document is detected by the sensor 3, the paper detection signal appearing on the signal line 11-a changes from "1" to "0" as shown in FIG. 2(A). ”. In this case, the image signal is normally shifted from A1 to A1 as shown in FIG.
A2 is delayed and appears on signal line 7-a. followed by I
(After the TC signal is output, as shown in FIG. 2(C), at the time of A3, the signal line 7-
A procedure start signal pulse is sent to the timer circuit 17 and the procedure signal generation circuit 15 via b. This results in Figure 2 (D
) as shown in FIG. signal) is generated and sent to the NCU 21. Therefore, a signal as shown in FIG. 2(F) is sent out from the line 33.

The signal transmitted from the facsimile machine in this manner is received at the receiving end, and in this case, the receiving end normally receives a plurality of images using a roll of recording paper. Some receivers are equipped with an automatic cutter inside the receiver to cut the recording paper according to the document. In particular, a facsimile machine with an automatic cutter is convenient for continuously receiving several sheets of originals, but the receiving and transmitting equipment themselves are expensive and large in size. Such an automatic cutter is omitted. Therefore, when multiple originals are received in succession, the roll of recording paper must be cut for each original, but the cuts on the received paper may not be clear, or there may be no cuts. This was a huge problem and took a lot of time.

Therefore, it is an object of the present invention to eliminate such conventional drawbacks and to provide an inexpensive and compact facsimile machine that can easily and accurately cut recording paper according to the original after receiving the original. This purpose according to the invention? In order to achieve this, a configuration is adopted in which when the reading of the original is completed and the image information is completed, an image signal for a marker is generated in response, and the marker signal is sent out and recorded.

That is, in the present invention, when the sending of the image information of one image is completed, the image signal for the marker sent out inside the transmitter is sent out, and on the receiving side, the image signal for the marker may be in the form of writing or simply as a landmark. It may be a mark that looks like this.

The present invention will be described in detail below based on embodiments shown in the drawings.

FIG. 3 shows a schematic configuration of a facsimile apparatus according to the present invention as a block diagram. In this figure, the same parts as in FIG. 1 are given the same reference numerals, and similar parts are given dashes, and detailed explanation thereof will be omitted. Third
In the illustrated embodiment, the reading and encoding section 7' is configured to output a marker start signal to the output line 7' immediately after the transmission of the image signal is completed, without outputting the RTC signal.

Since the marker start pulse may be the same pulse from a hardware point of view as the procedure start signal in FIG. It is possible to have a configuration in which only the function of outputting an RTC signal is removed. Further, in the present invention, a marker signal generating circuit 23 is provided, and this marker signal generating circuit 23 receives a signal from the signal line 7'-- and outputs the signal from its output line 2.
Signals are generated at 3-a, 23-b, and 23-c, respectively. The switch circuit 25 switches between the signal lines 7'-a and 23-a based on the signal from the signal line 23-a of the marker signal generating circuit 23.
It has a function of connecting either one of the output terminals b to the output 19-a.

Next, the operation of the facsimile machine configured as described above will be explained.

At the time B1 in FIG. 4(A), the paper detection signal changes from "1" to "0".
” and the end of the document is detected.

At this time, as shown in FIG. 4(B), the image signal is delayed until the time point B2 for the reason mentioned above, and then is transmitted via the signal line 7'-b as shown in FIG. 4(C). A marker start signal is output. This marker start pulse activates the marker signal generation circuit 23, and a marker signal is output as shown in FIG. 4(D).

This marker signal consists of, for example, an image signal for several lines in a broken line pattern. Subsequently, when the output of the marker signal ends at the time point B4, the RTC signal is subsequently sent out until the time point B6. Since the marker sending signal shown in FIG. 4(E) is "1" from B2 to B5, the switch circuit 25 is switched to the lower side and the signal between them is input to the modulator 9, and then the signal is input to the modulator 9. The signal is sent to line 9-a.

Also, at the time of B5 in Fig. 4(E), the marker sending signal is "1".
When the output of the RTC signal is completed, the procedure sending signal pulse shown in B6 of FIG. 4(F) is output from the timer circuit 17' as shown in FIG. 4(H). As described above, the procedure sending signal is sent out, the switch circuit 19 is switched to the lower side, and the 1 procedure signal generating circuit 15 sends out the EOM signal as shown by -1 in FIG. 4(I). Therefore, a transmission signal as shown in FIG. 4(J) is input to the NCU 21 and sent out through the line.

The information sent in this way is recorded on the receiving side, and an example of this is shown in FIG. There is. Incidentally, FIG. 5(A) shows a conventional recording state in which such a broken line is not provided.

In the above example, the marker signal generation circuit outputs a signal indicating a broken line pattern, but other patterns such as a black line or a dashed-dotted line can be considered, and it is also possible to output a telephone number, transmission date and time, etc. In addition, although the above-mentioned embodiment has been explained as a G■ sofa-similar device, it is a GI.

The present invention can be applied to GII transmitters in exactly the same way.

As explained above, according to the present invention, the marker signal is sent after the image information is completed, and since this is recorded on the receiving side, the receiving side can receive the marker signal even after receiving multiple originals in succession. Boundaries between documents can be easily identified along the marker signal, and roll-shaped recording paper can be easily cut to accommodate a plurality of documents.
