Abstract

PURPOSE:To replace recording paper without interrupting current communication by requesting the replacement of a recording medium when the remaining quantity of the recording medium is < a prescribed length is detected, and delaying the reception of printing information is response to the request. CONSTITUTION:If a recording part 15 detects a black band mark indicating that the remaining quantity of recording paper is prescribed length or less during the decoding of an image signal in a decoding part 14 and the reproducing of an image by the recording part 15, an alarm 17 for informing the small quantity of the recording paper to the operator is turned on. Then, the operator depresses the switch 18 to indicate the replacement of the recording paper. Then, the alarm 17 is stopped and a lamp 19 is turned on to inform the acceptance of the depression of the switch 18 to the operator. When the reception of an image signal of one page is ended, the replacing timing of the recording paper is informed to the operator. Simultaneously with the information to the operator, the reception of the printing information is delayed for a prescribed time under the connected state of the circuit.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transmission device such as a facsimile device,
In particular, the present invention relates to a transmission device that allows recording paper to be replaced without interrupting communication even during communication.

[Prior Art] Taking a conventional facsimile machine as an example, the operation when the recording paper runs out during one communication will be described below.

In a facsimile machine, processing when the recording paper (roll paper) runs out during one communication can be broadly classified into the following three types.

The first method is to continue recording reception as long as there is recording paper, and stop receiving when the recording paper runs out.After the sending facsimile machine finishes transmitting the information, the receiving facsimile machine completes receiving the information. Since the signal cannot be received, the process ends with an error.

Normally, this error termination always occurs for each roll of paper, and when this error occurs, the operator on the receiving side must reset the recording paper, and the operator on the sending side must reinstall the document in which the error occurred on the document table. and then have to make the call again.

The second is a predetermined length from the end of the recording paper (for example, about 60 cm)
Using recording paper with marks such as black bands on the back side of the paper, if a black band is detected while receiving one communication, only the currently received page will be received and the next page will not be received. It is something.

Compared to the first method, this method eliminates the need to interrupt reception while receiving one page of image signals, but like the first method, it requires both the operator on the transmitting side and the operator on the receiving side. There is a problem in that unless it is shifted, the untransmitted original cannot be transmitted.

The third method is to store received data that cannot be recorded because the recording paper has run out in a memory. However, even with this method, the memory capacity of the facsimile device is limited, so if there are many untransmitted documents on the sending side, there will not be enough memory to record the received data, resulting in the same problem as the above method. will occur.

[Problems to be Solved by the Invention] In addition, when the receiving side uses recording paper with the aforementioned black band attached, and when the recording paper becomes less than a predetermined length, that is, a black band is detected, an alarm is generated and the operator is instructed to record the paper. There is a device that notifies you when there is little paper left. However, this device also has the drawback that the operator cannot replace the recording paper until the current communication has ended. Another drawback is that the receiving side cannot recognize whether there are still documents to be sent on the sending side.

The present invention has been made in view of the above-mentioned conventional example, and provides a transmission device capable of replacing the recording paper without interrupting the current communication operation when it is detected that the remaining recording paper has become less than a predetermined length. The purpose is to

Another object of the present invention is to provide a transmission device that allows the receiving side to detect whether there is an unsent document on the transmitting side when the receiving side detects that the length of recording paper has become less than a predetermined length. shall be.

[Means for Solving the Problems] In order to achieve the above object, the transmission device of the present invention has the following configuration. That is, a printing means for printing the received print information, a detection means for detecting that the remaining amount of the recording medium of the printing means has become less than a predetermined amount, and an instruction for requesting conversion of the recording medium and instructing completion of the exchange. means for displaying that the recording medium is replaceable in response to the instruction means; and display means for delaying reception of the print information for a predetermined period with a line connected in response to the instruction means. and delay means.

Further, the transmission device of the present invention that achieves the above-mentioned other objects has the following configuration. That is, a printing means for printing the received print information, a detection means for detecting that the remaining amount of the recording medium of the printing means has become less than a predetermined amount, and an instruction for requesting conversion of the recording medium and instructing completion of the exchange. means, display means for displaying that the recording medium is replaceable in response to the instruction means, and means for displaying whether there is an unsent document on the sending side in response to the instruction from the instruction means; and a delay means for delaying reception of the print information for a predetermined period of time with a line connected when the unsent document exists.

[Operation] In the above configuration, when the operator detects that the remaining amount of the recording medium of the printing means that prints the received print information has become less than a predetermined amount, the operator issues a request for converting the recording medium and an instruction to complete the exchange using the instruction means. conduct. In response to this instruction means, the display means displays that the recording medium can be replaced, and in response to the instruction means, the reception of print information is delayed for a predetermined period while the line is connected, and the recording paper is replaced. It operates in such a way that it buys the time required.

According to another configuration, when the operator detects that the remaining amount of the recording medium of the printing means for printing the received print information has become less than a predetermined amount, the operator uses the instruction means to issue a recording medium conversion request and exchange completion instruction. conduct. In response to the instruction means, it is displayed on the display means that the recording medium can be replaced, and in response to the instruction from the instruction means, it is displayed on the sending side whether or not there is an unsent document. When there is an unsent document, the reception of the print information is delayed for a predetermined period while the line is connected, so as to buy the time required to replace the recording paper.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[Description of the structure of the facsimile machine (FIG. 1)] FIG. 1 is a block diagram showing the structure of the facsimile machine of this embodiment.

In the figure, 1 is connected to the terminal of telephone line 2 in order to use the telephone network for data communication, etc., and according to instructions from control unit 3, it controls connection to the telephone exchange network, controls switching to the data communication path, and maintains the loop. Network control unit N CU (Ne
tlnit). 3
is a control unit that controls the entire device, for example, a ROM that stores control programs and data for the CPU such as a microprocessor, and an RA that serves as a work area for the CPU.
Equipped with M etc. 4 is a telephone for voice calls, NC
U1 switches and connects the telephone line 2 to the telephone 4 side or the facsimile machine side (the hybrid circuit 6 side) in accordance with the switching signal 5 from the control section 3. It is assumed that the telephone line 2 is normally connected to the telephone 4 side.

6 is a hybrid circuit that separates the transmitting system signal and the receiving system signal, and the transmitting signal is manually input from the adding circuit 7 to the NCU1.
The received signal sent from the other party via the NCUI is output to the demodulator 8.9. 8 is a known CC
A demodulator that performs demodulation based on the ITT Recommendation V, Recommendation Standard, 9 is a demodulator that performs demodulation based on the known CCITT Recommendation V, Recommendation Standard er (differential phase modulation) or V,29 (orthogonal modulation) to generate an image signal. This is the input demodulator.

10 is a modulator that performs modulation based on the well-known CCITT Recommendation V and recommendation and outputs a control signal from the control unit 3; 11 is a well-known CCITT Recommendation V and Recommendation ER (differential phase modulation);
Alternatively, it is a modulator that performs modulation based on V,29 (orthogonal modulation) and sends out an image signal. Reference numeral 12 denotes a reading section composed of an image pickup device such as a CCD (charge coupled device) and an optical system, which photoelectrically scans the document and outputs a binary pixel data string. The encoding circuit 13 is an encoding circuit that manually inputs this binary image data string and performs, for example, MH encoding or MR encoding.

A decoding circuit 14 decodes the image signal demodulated by the demodulator 9, and performs, for example, MH decoding, MR decoding, etc., and outputs image data to the recording unit 15.

The recording unit 15 sequentially records on the recording paper line by line.
For example, it is a thermal line printer.

Further, when the recording section 15 detects that the remaining amount of recording paper is small from the aforementioned black band mark on the recording paper, it notifies the control section 3 by the paper out signal 16 that there is little remaining recording paper.

The paper out signal 16 indicates that the amount of recording paper remaining is low.
When the control unit 3 detects this, it turns on the lamp or buzzer of the alarm 17 to prompt the operator to replace the recording paper. When the operator wants to replace the recording paper, he presses the switch 18.

As a result, the lamp 19 lights up, indicating that the depression of the switch 18 has been accepted by the control unit 3.

When the control unit 3 finishes receiving the page currently being received, it flashes the lamp 20 to indicate that the recording paper can be replaced.

The recording paper is replaced by the operator and switch 1 is pressed again.
When the button 8 is pressed, the control unit 3 turns off the lamp 19 to indicate that the recording paper has been replaced, and starts the next receiving operation. Display section 21
For example, if there is an untransmitted document on the sending side at the time of replacing the recording paper, a message such as "Madagenkouari" will be displayed, and if there is no untransmitted document and the sending side has finished sending, a message such as "Owari" will be displayed. This is the display section.

[Operation description (Figures 1 and 2 (A) to (C))] Figures 2 (A) to (c) are flowcharts of the control program stored in the ROM of the control unit 317. The process starts when the power of the facsimile machine of this embodiment is turned on.

First, in step S1, the NCU1 and telephone 4 are connected by the switching signal 5, and the CML is turned off, and in step S2, both the lamp 19, 20 and the alarm 17 are turned off. It is checked in step S3 whether the reception mode has been selected, and if it is not the reception mode, corresponding processing is performed in step S4.

When the reception mode is selected in step S3, step S5
Proceed to , connect the NCUI and hybrid circuit 6, and
Turn on ML. In step S6, a digital identification signal, a reception preparation confirmation signal, etc. are sent out to execute a pre-procedure for image signal reception. In step S7, the image signal is received through the demodulator 9, decoded by the decoding circuit 14, and reproduced by the recording section 15.

In step S8, it is checked by the paper out signal 16 whether the recording section 15 has detected a black band mark indicating that the remaining amount of recording paper is less than or equal to a predetermined length. If the black band mark is not detected, the process proceeds to step s9, and it is checked whether the EOM message has been received, that is, whether the reception of the image signal has been completed. If the reception of the image signal is not completed, the process returns to step S7 and the reception of the image signal is continued, but when the reception of the image signal is completed, the process returns to step S7.
At O, a message confirmation signal (MCF) etc. is output, the post-procedure is executed, and the process returns to the start again.

When it is detected in step S8 that the paper out signal 16 has been turned on, the process proceeds to step Sll, where an alarm is turned on to notify the operator that there is little recording paper remaining. In step S12, CNT in the RAM of the control section 3 is set to 0', and in step S13 it is checked whether the operator has pressed the switch 18 to instruct to replace the recording paper. If the switch 18 is not pressed, steps S14 and S15 wait until the reception of one page of the image signal currently being received is completed, and when the reception of the image signal of one page is completed, the intermediate processing is performed in step S16. Or perform post-procedures. In step S17, it is checked whether there is still a document to be transmitted on the transmitting side, that is, whether a multi-page signal (MPS) has been received.

When there is no document to be sent on the sending side (when an EOM message is received), all image signal reception has been completed, so there is no need to rush to replace the recording paper, and the process advances to step 31B to send the CM.
L is turned off, and the process waits for the switch 18 instructing to replace the recording paper to be pressed in step S19. At this time, the display section 21 displays "Owari".

When the switch 18 is pressed in step 19, the alarm 17 is stopped in step 20, and the lamp 19 indicating that the switch 18 is turned on is turned on. In step S21, the lamp 20 blinks to inform the operator that it is OK to replace the recording paper, and in step S22, the switch 18 is pressed again to indicate when the recording paper has been replaced. After waiting, when the recording paper has been replaced, the recording paper is cut in step S23 and the process returns to the start.

On the other hand, when a multi-page signal (MPS) is received in step S17, the process advances to step S33, and it is checked whether CNT in the RAM is "0". If CNT is not "0°", the process advances to step 318 to stop the reception. However, if the CNT is °゛0°゛, in step S34, the CNT is
' is set, the process returns to step S13, and the process waits for the switch 18 to be pressed, which is an instruction to replace the recording paper, or for the reception of image signals for one page to be completed. For example, when the operator is away from the apparatus and there is a delay in pressing the switch 18, the system waits for the recording paper to be replaced for the reception time of the next page of the original document. At this time as well, the display section 21 displays the message "Madagenkouari" to inform the receiver on the receiving side that the sending of the document from the sending side has not been completed.

When the switch 18 is pressed in step S13 and the operator instructs the operator to replace the recording paper, the process proceeds to step S24 to stop the alarm 17, turn on the lamp 19, and notify the operator that the switch 18 has been turned on. Step S25. In step S26, wait until the reception of the image signal for one page is completed, and when the reception is completed, in step S27, the lamp 2 is turned off.
0 blinks to notify the operator that it is time to replace the recording paper. In step S28, an intermediate or post-procedure is executed, and in step S29 it is checked whether an MPS signal (multipage signal) has been received. When an EOM signal is received instead of an MPS signal, the process proceeds to step S30, and the C
The ML is turned off and a message such as "Owari" is displayed on the display unit 21, and the process proceeds to step S22, where it waits for the recording paper to be replaced.

Upon receiving the MPS signal in step S29, step S3
Proceed to step 1 and check whether the Q signal from the transmitting side has been received three times.

If the Q signal is not received three times, the process advances to step S32;
The switch 18 is used to check whether the recording paper has been replaced. When the Q signal is received three times in step S31, the process proceeds to steps 335 to 53B. When the EoM is received, the message confirmation (MCF) and digital identification signal (DIS) are transmitted, and when the MPS signal is received, the retrain process (RTP) is performed.
) The time from when the signal is sent to when the recording paper is replaced is saved by the control procedure.

After this, an intermediate procedure is executed in step S39, and step S
At step 40, it is checked whether the recording paper exchange is completed by pressing the switch 1B, and if the switch 18 is not pressed, the process goes to step 33.
In steps 9 to S41, it is checked whether it is time to receive the next image signal.

When the image signal reception timing is reached in step S41, it is assumed that the recording paper has not been replaced within a predetermined period of time, and the process proceeds to step 318, where reception is interrupted and the process waits for the recording paper to be replaced.

On the other hand, when the switch 18 is pressed within a predetermined time in step 340 and it is notified that the recording paper has been replaced, the process advances to step S42 to turn off the display on the lamp 20 and the display section 21, and in step 343 the recording paper is cut. do. Next, in step S44, an intermediate procedure is executed, and the process returns to step S7 to execute the above-described image receiving operation.

As explained above, in this embodiment, when the operator wishes to replace the recording paper, the operator is notified at the page break of the image information that the recording paper can be replaced, and the operator takes the time required to replace the recording paper. This operation allows the recording paper to be replaced without interrupting communication with the other party's transmitter.

In the case of a facsimile machine equipped with a memory that can store received image data, when the operator is replacing the recording paper, the image information of the next page is stored in the memory, and the information from the next page is stored. It may also be recorded. By doing this, the image information can be received even while the recording paper is being replaced, so there is an advantage that the image information transmission time can be shortened compared to the present embodiment.

As explained above, according to this embodiment, even if a facsimile machine runs out of recording paper during one communication and there is still an untransmitted document on the transmitter side, the recording paper can be replaced while the line is connected. Therefore, it has become possible to transmit untransmitted original documents without the intervention of an operator on the transmitter side.

Although the present embodiment has been described in the case of a facsimile machine, the present invention is not limited thereto, and can also be applied to a transmission device connected to a LAN or the like that receives and prints out image data or print data, for example.

[Effects of the Invention] As described above, according to the present invention, there is an effect that the recording paper can be replaced without interrupting the communication operation and without intervention by the operator on the transmitting side.
