Abstract

PURPOSE:To detect a jam of the recording paper which is caused when the transmission is continuous by providing a means to stop temporarily a continuous medium and stopping the medium after the medium is cut to carry the continuous medium with a prescribed distance set to the cut medium. CONSTITUTION:The recording paper 1 is carried by a carrying mechanism containing a carrying motor 8, a discharged motor 6a, etc., and the recording is consecutively carried out between pages of the paper 1 through a recording part 3. The recorded paper 1 is cut by a cutter 4 and detected at a discharge part 6 to be stored in a store part 7. A temporary stop means of the paper 1 containing counters 9 and 10, a sensor 5, etc. is provided to the carrying mechanism. The counter 9 is started after the start of recording and reset within a fixed period of time by the detection signal of the sensor 5. Then a carrying motor driving circuit 8a is stopped within a prescribed time after the cutter 4 is driven. At the same time, the motor 8 is stopped temporarily after the recording is over with the counter 10 and when the paper 1 is cut while recording the next page. Then a cutter driving circuit 4a is actuated to assured the continuous recording.

Description

[Detailed Description of the Invention] ia1 Technical Field of the Invention The present invention relates to a receiving and recording device for a facsimile communication device, and more particularly to a recording device that can detect jams in recording paper even when transmission is continuous. .

(b) Technical Background Recently, facsimile communication has been put into practical use for transmitting documents, figures, etc. to remote locations using communication lines. In facsimile communication, sending and receiving devices between users are connected through a communication line and documents are exchanged between users.The image of the original document on the sender's side is scanned using an image sensor, for example, in main scanning and vertical scanning, which scans horizontally written documents in the horizontal direction. The image data is transmitted as an electrical signal by scanning in the sub-scanning direction, that is, the document feeding direction, and the receiving side receives the transmitted image data and records it on, for example, thermal paper to reproduce the document. It is something.

There is also a method that uses a telephone line for the line.

With the spread of facsimile communication, communication processing time has become faster, and with this, it has become even more important to ensure system reliability.

(C1 Prior Art and Problems The conventional method will be explained below with reference to FIGS. 1 to 3, taking the receiving section of a facsimile transmitting/receiving device as an example. FIG. 1 is a side view showing an overview of the receiving section mechanism; 2 and 3 are explanatory diagrams of the conventional method.

As shown in FIG. 1, the receiving section includes a reception control section (not shown) that receives transmitted signals, a paper feed section 2 storing a roll of thermal recording paper 1 (hereinafter referred to as "recording paper"), and a recording section A recording unit 3 that records on paper I with a thermal head 3a and a recording unit roller 3b to create a received document, a cutter unit 4 that cuts the recording paper 1, and a cutter unit 4 that makes sure that the cut paper 1a passes in a predetermined feeding time. Detecting the leading edge and trailing edge of document 1a,
It has a sensor 5 for confirming that no jam has occurred, a discharge section 6 for discharging the cut document 1a, and a storage section 7 for storing the discharged document 1a, which are arranged in this order. There is. Therefore, the recording paper 1 is recorded in the recording section 3 while being fed by the recording section roller 3b, cut by the cutter section 4 according to the size of the document to be sent, and sent to the discharge section 6.
The document 1a is stored in the storage section 7, but the document 1a is
The leading and trailing ends of the sensor 5 are detected by the sensor 5, and correct feeding is confirmed by turning ON and OFF. If this sensor 5
If it is not turned off, it is determined that a jam has occurred, the apparatus is stopped, and a notification is issued by an alarm means (not shown).

In this case, when the document 1a is cut by the cutter section 4, the leading edge of the recording paper I is naturally at the position of the cutter section 4, and since there is a margin between pages, the recording section roll paper 3b is reversed and the recording paper I is cut next. After the page is moved back to the starting position, the next recording is started.

That is, as shown in Fig. 2, image data is sent in the form of a signal from the transmitting side, and is stored one after another in the sofa memory of the reception control unit and recorded on the recording paper 1, and -pages worth of data are transmitted. In other words, when the transmission of the entire page including the margins of the original document on the sending side is completed, the next page is moved, but the feeding of the original document on the sending side and the retreat of the recording paper 1 on the receiving side during continuous transmission, etc. There is a loss time between pages, and for this reason 1~
It takes 2 seconds and the transmission is stopped during this time.

After the recording position of the next page is determined, a recording completion response is sent and the image data of the next page is transmitted.

Manogo Shinoi'7. For devices with an error-free function that performs error-free retransmission when an error occurs, even if the last frame is received, it is not possible to record that frame. is further the number I
There are two types, one with a small IJ. Fully I frame 5I
2 hides, the number of lines encoded in this is several white -
It may be included near the line. To record this, if it takes 10m5J to record one line, it would take about 11 seconds or more (fJ), which could have been transmitted in 10 seconds, and during this time the transmitting side would stop, resulting in loss time.

However, as communication processing speeds up, the sentence 'p'rja
With the arrival of 62 people, who are now able to process an A4 size paper in around 10 seconds, the above-mentioned l:J input time has become a problem that cannot be overlooked.

Therefore, it is conceivable to continuously transmit the frames of the next page as long as the Hanwha memory allows, before recording the entire final frame. That is, as shown in FIG. 3, when the transmission of -pages is completed, a response is immediately sent and image data of the next page is transmitted.

However, according to this method, when the previous page has been recorded and the next page is recorded, the recording paper 1 stops and is cut when it reaches the position of the cutter unit 4, but the paper is cut with almost no gap after cutting. sent and recorded. This is effective because there is no break between pages, but jam detection becomes a problem because the pages become blank. In other words, if the detection of the sensor 5 does not turn OFF within a certain period of time after cutting the recording paper 1, it is possible that the sensor will turn ON due to the next page before it turns OFF, and a true jam will occur. The disadvantage is that the device will stop and an alarm will be issued if the paper jams and the paper jams.

It is conceivable that recording may be stopped for a period of time until detection is turned off at the trailing edge of the recording paper 1, but this will result in a loss of time.

(d) Purpose of the Invention The purpose of the present invention is to solve the following drawbacks:
To provide a recording device capable of detecting a jam of recording paper even when transmission is continuous.

(+1 of c1 invention) The present invention has a stop means for temporarily stopping the continuous medium.
J is a recording device characterized in that after the medium is cut, the continuous medium is stopped by a stopping means, and the continuous medium is transported at a predetermined distance from the cut medium, and the continuous medium is thus The purpose can be achieved by

An embodiment of the present invention other than the embodiment of the ff1 invention will be described with reference to the block diagram of FIG. In FIG. 4, 4.3 is a cutter drive circuit, 5a is a sensor detection circuit, LJ)a is an ejection motor, 8 is a motor for transporting recording paper, 8a is a transport motor drive circuit, 9 and 10 are counters, and 11 is a The discharge motor drive circuit includes an AND circuit 12 and an OR circuit 13.

The counter 9 is a counter for detecting a jam, and after the start of recording, the star is set to 1, and within a certain period of time it is reset when the sensor 5 detects it. Time T1, T2 to stop the recording motor 8 after the time (here, TI<T2
) is set, and at time T1, a signal is sent to the transfer motor drive circuit 8a, and at time T2, a signal is sent to the sensor detection direction path 5a. However, the time T1 is the time taken until the recording paper 1 comes to a position slightly before the sensor 5. The counter 10 is for feeding further to the position of the cutter 4 while recording the next page after recording is completed.
It has a function of temporarily stopping the motor 8 when cutting the recording paper 1 and activating the force/vine drive circuit 4a.

The sub-scan clock is sent to the counter 9.10 and the recording motor drive circuit 8a.

With such a configuration and function, during the recording operation, the recording motor drive circuit 8a operates, the motor 8 is driven, and the recording paper 1 is fed out for recording, and when the recording is completed, the margin is fed. , recording of the next page begins. At this time, the leading edge of the recording paper 1 has already been detected by the sensor 5 and turned on. Further, the discharge motor a is driven during the recording operation.

The motor 8 is stopped by a signal from the counter 9 at the time when the cutter 4 reaches the cutter 4, and the cutter drive circuit 4. ．． When I operates, the cutter 4 cuts and ejects the recording paper 1, and at the same time drives the motor 8 to start recording the next page.At the same time, a signal is sent from the counter 9 to the counter 8 to start the recording after cutting W1. Time is counted. When the time TI is reached, a signal is output, the motor 8 is stopped, the next page of recording paper 1 is stopped, and the cut recording paper 1. That is, since the document 1a is sent as it is by the output unit 6, there is a gap between the document 1a and the next page of the recording paper 1, and when the next page is recorded, the IE 1 starts recording again by the recording signal and is sent. . Therefore, when time T2 is reached, a signal is output from the counter 9 to the sensor 9' detection circuit 5a, and when the sensor 5 detects the trailing edge of the 'ζ document la, there is no interference from the next page and if the feed is normal. The detection is turned off and the counter 9 is reset. If the detection is ON
If it is, you can definitely determine that the jam is raw.

Of course, when the sensor 5 is in front of the sensor 5, that is, when the time TI has elapsed and the sensor 5 is in the detection OFF state, recording continues without pausing.

In this way, the previous page is ejected, and the next page is recorded and fed until it reaches the sensor 5.
When is ON, it pauses and hides for a while, and then the previous page and l'? I got an A and recorded it again.

During the feeding, it is monitored that the sensor 5 is turned off. In this way, jam detection can be performed with almost no lost time. Of course, there is no need to leave blank spaces between pages.

(g1 As described in detail of the invention, according to the present invention, in the method of accelerating the crystallization speed by continuously performing recording, there is an interval between the previous page and the next page, so jam detection is possible. This has the advantage that it can be done accurately.
