Description

Description: TECHNICAL FIELD The present invention relates to a document receiving apparatus, and more particularly, to a document in which a delay of at least one page occurs between a page being recorded and output and a page being received. Related to a receiving device.

(Prior Art) Recently, in the information age, various devices for communicating documents have appeared. As a document receiving device, for example,
Facsimile machines and the like have become widespread.

Conventionally, in this facsimile apparatus, a thermal recording apparatus is generally used as a recording apparatus, and records and outputs a received document in real time.

However, such a thermal recording apparatus has a problem that the recording quality is poor and the recording speed is low.

Therefore, recently, a document receiving apparatus using a high-speed recording apparatus with good recording quality, such as a laser recording apparatus, has appeared as a recording apparatus.

However, a high-speed recording apparatus having a good recording quality such as a laser recording apparatus is generally a so-called non-real-time recording apparatus that records a document in page units. Therefore, the document receiving apparatus has a document storage unit and receives a document. After the document is temporarily stored in the document storage unit, the document is output to this non-real-time recording apparatus in page units and recorded and output on recording paper.

On the other hand, in a document receiving apparatus provided with a document storage unit, a normal mode in which reception and recording are performed in parallel, and a memory reception mode in which all pages of a received document are temporarily stored in the document storage unit and then recorded and output by the recording unit. The memory reception mode is used when the recording device cannot be used due to no recording paper or recording paper jam, or when electronic sorting that reverses the page order after reception or when transferring received documents. Have been. In this memory reception mode, automatically switching to the memory reception mode when the recording device cannot receive in the normal mode due to an error or the like and performing reception is generally referred to as alternate reception, and in a document reception device such as a facsimile device, When the recording device cannot be used due to an error or the like, it is automatically switched to alternate reception to perform reception.

(Problems to be Solved by the Invention) However, in such a document receiving apparatus equipped with a conventional non-real-time recording apparatus, when an error occurs in the non-real-time recording apparatus, etc., an alternate reception mode is automatically set. Therefore, there has been a demand for a document receiving apparatus capable of appropriately setting the alternate reception prohibition mode.

That is, some users may feel uneasy about leaving the document data stored in the document storage means,
When an error occurs in the recording device, the document storage unit becomes full of documents received in the memory, and other functions of the document transmitting / receiving device that do not use the recording device (for example, memory transmission, reception of a confidential document, and memory transmission reservation) are used. To avoid being unable to do so, there is a need for a document receiving apparatus that can appropriately set an alternate reception prohibition mode that inhibits alternate reception.

However, if a general proxy reception inhibition mode is provided for a document receiving device using a non-real time recording device, if an error occurs in the recording device during reception, communication is interrupted, and at the time when the error occurs in the recording device, Since the document of the page which is normally received and stored in the document storage unit but is not recorded because of an error in the recording unit and remains in the document storage unit is set in the alternate reception prohibition mode, the document In addition to not being able to effectively use the document of the page normally received and deleted from the storage means, the document of the page received normally must be sent to the transmission side again, which causes a problem that communication cost is required. .

(Objects of the Invention) In a document receiving apparatus provided with a non-real-time recording apparatus, when an error of a non-real-time recording means is detected during reception of a document, a predetermined control signal is transmitted to the other party. After outputting to the communication terminal and notifying the partner communication terminal that an error has occurred in the receiving page, the communication is interrupted, and the document normally received and stored in the document storage unit is saved before the error occurs. A method of recording and outputting after recovery of the recording means so that an alternate reception prohibition mode in which a document of a normally received page can be effectively used can be set and communication costs can be reduced. According to the described invention, when an error occurs in the non-real-time recording unit during document reception, a predetermined control signal is output to the partner communication terminal and an error is displayed on the page being received. After notifying the other communication terminal that the error occurred, the communication was interrupted, and a control signal indicating that the communication was normally received before the occurrence of the error was transmitted, and the document stored in the document storage unit was normally recorded by the recording unit. The determined page is deleted from the document storage unit, and after the recording unit is restored, the received document of the page stored in the document storage unit is recorded and output, and the document storage unit is effectively used, and the normally received document is validated. It is intended to be used.

 Hereinafter, a specific description will be given based on examples.

FIGS. 1 to 5 are diagrams showing an embodiment of the document receiving and outputting apparatus according to the second and fourth aspects of the present invention (the first and third aspects of the invention are the same document receiving and outputting method). is there.

FIG. 1 is a block diagram of a facsimile apparatus 1 as the document receiving apparatus. The facsimile apparatus 1 includes a network control unit 2, a modem 3, a FIFO memory 4, an ECM buffer 5, a line buffer 6, a document storage unit 7, a page The system includes a memory 8, an encoding / decoding unit 9, a system control unit 10, a scanner 11, a plotter 12, an operation display unit 13, and the like.

A line L, for example, a telephone line is connected to the network control unit 2, and the network control unit 2 is generally called AA-NCU. The network control unit 2 sets and releases a call.

The modem 3 modulates a transmission signal into a form suitable for transmission on the line L when transmitting, and demodulates a modulated signal sent from the line L when receiving.

The FIFO memory 4 is a memory for temporarily storing image information. For example, the FIFO memory 4 stores received image information in the order of reception, and sequentially outputs the received image information in the order of storage.

The ECM buffer 5 is a buffer memory for temporarily storing image information when performing communication by the ECMC method.
During ECM communication, the received image information is stored in the order of reception, and is sequentially output in the order of storage. This ECM communication is half-duplex page selection correction ARQ
This is an error correction method based on the (Automatic Repeat Request) method, in which the transmitting facsimile device divides the encoded data into a number of frames and transmits each frame with a frame number, and the receiving facsimile device is normally received. If not, a retransmission request is made by designating the frame number.

The line buffer 6 is a buffer memory for internally processing image information in the facsimile machine 1 and has a capacity to store image information for several lines.

The document storage unit 7 has a predetermined capacity and stores received image information and transmission image information. The image information for transmission and the received image information are stored in the document storage unit 7, read out at a predetermined time, and subjected to transmission processing and recording output processing.

The page memory 8 has a capacity for storing at least one page of image information. For example, when one page of received image information is stored, the page information is output to the plotter 12 for recording.

The encoding / decoding unit 9 shortens the transmission time of the image information and increases the efficiency. The image information is compressed (encoded) at the time of transmission, and the encoded image information is converted to the original information at the time of reception. To be reproduced (decoded).

The system control unit 10 includes ROM (Read Only Memory), RAM
(Random Access Memory) and CPU (Central Process)
In addition, a basic program as the facsimile machine 1 and a program for receiving and recording image information of each invention of the present application are stored in the ROM in advance. The system control unit 10 controls each unit of the facsimile machine 1 in accordance with a program in the ROM to execute a sequence as the facsimile machine 1 and executes image information receiving / recording processing of each invention of the present application.

As the scanner 11, for example, a CCD (Charge Coupled
The scanner 11 reads a document for each line and outputs it as image information.

As the plotter 12, for example, as shown in FIG.
A laser recording device is used, and a plotter 12 includes a polygon mirror 21, a mirror 22, a photosensitive belt 23, and a roller 2.
4, developing unit 25, transfer unit 26, cleaning unit 27, fixing unit 2
8, a cassette 29, a separation unit 30, a feed roller 31, a paper discharge roller 32, and the like. Recording paper in cassette 29
33 is stored, and the recording paper 33 in the cassette 29 is separated
The sheets 30 are separated one by one and fed to a feed roller 31. The procedure of the feed roller 31 includes a recording paper sensor.
34 is provided, and the recording paper sensor 34 is a feed roller
The leading and trailing ends of the recording paper 33 sent to 31 are detected and output to the system control unit 10. The feed roller 31 conveys the recording paper 29 to the transfer unit 26 and the fixing unit 28, and the discharge roller 32 discharges the recording paper 29 on which the recording has been performed, outside the plotter 12, that is, outside the facsimile machine 1. A recording paper sensor 35 is provided behind the paper discharge roller 32. The recording paper sensor 35 detects the recording paper 33 discharged by the paper discharge roller 32 and outputs the recording paper 33 to the system control unit 10. On the other hand, the photoreceptor belt 23 is rotated by the roller 24, and light modulated by image information at the writing position W is applied to the photoreceptor belt 23 via the polygon mirror 21 and the mirror 22. An electrostatic latent image is formed on the photoreceptor belt 23 by this light, and the transfer unit 26
Then, the toner 25a is adhered and developed. The photoreceptor belt 23 to which the toner 25a is attached is further rotated, and the transfer unit 26 transfers the toner 25a of the photoreceptor belt 23 to the recording paper 33 that has been conveyed to the transfer unit 26. The photoreceptor belt 23 is further rotated, the toner 25a is removed by the cleaning unit 27, and after the charge is removed by the charge removing unit 36, light is irradiated again at the writing position W to write the electrostatic latent image.

The plotter 12 uses a laser as a light source. When one page of image information is stored in the page memory 8, the plotter 12 receives the image information and irradiates a high-speed modulated light onto the photosensitive belt 23. To record. Therefore, the plotter 12 records image information of a page at least one page behind the page of the received image information, and constitutes a so-called non-real-time type recording means.

The operation display unit 13 includes various operation keys such as a numeric keypad and a start key, and also includes a display (for example, a liquid crystal display). Various commands are input by operating the operation keys, and the input contents and the facsimile machine 1 Displays various information transmitted to the operator on the display.

Since the facsimile apparatus 1 has the document storage section 7, it can perform normal memory transmission / reception, and has a conventional image information storage memory when memory reception is not set. Similarly to the facsimile apparatus, when an error occurs in the plotter 12, the received image information is stored in the document storage unit 7, that is, so-called alternate reception is performed. Further, the facsimile apparatus 1 can prohibit the alternate reception by a key operation of the operation display unit 13.

 Next, the operation will be described.

The present invention is characterized in that the alternate reception prohibition mode can be set without losing the normally received image information, and duplicate recording can be prevented. Hereinafter, the reception / recording process in the alternate reception inhibition mode will be described.

First, the receiving process in the alternate receiving mode will be described with reference to FIGS.

FIG. 3 is a sequence diagram at the time of alternate reception by a normal facsimile communication method not based on the ECM method. In this method, the facsimile apparatus 1 communicates with the partner facsimile apparatus when a call is transmitted from the transmitting facsimile apparatus. A normal facsimile control signal is exchanged between the two to start receiving image information. When the facsimile apparatus 1 normally receives the image information of the first page (indicated by P1 in FIG. 3), it transmits an MCF signal (message confirmation signal) and starts receiving the next page. The facsimile apparatus 1 modulates the received image information with the modem 3 and puts it into the FIFO memory 4, sequentially takes it out from the FIFO memory 4, decodes it with the encoding / decoding unit 9, sets it in the line buffer 6, and stores the document. The image information that is not decoded by the encoding / decoding unit 9 or the image information that has not been decoded by the encoding / decoding unit 9 is encoded by the encoding / decoding unit 9 and then encoded / decoded again.
The image information encoded by the decoding unit 9 is stored. Next, when one or more lines of image information are accumulated in the line buffer 6, the image information is transferred from the line buffer 6 to the page memory 8, and
When one page or more of the image information is stored in the page memory 8, the image information is transferred to the plotter 12 and recorded on the recording paper by the plotter 12.

The above operation is repeated for each page, and if an error (indicated by ER in FIG. 3) occurs during the reception of the third page, the facsimile apparatus 1 transmits the MCF signal because it is in the alternate reception mode. Then, the receiving operation is continued.

Next, the reception / recording processing in the alternate reception mode by the ECM method will be described with reference to FIG.

FIG. 4 is a sequence diagram at the time of alternate reception according to the ECM system. In the case of this system, the facsimile apparatus 1 performs facsimile control according to the ECM system with the partner facsimile apparatus when there is a call from the transmitting facsimile apparatus. The signals are exchanged to start receiving image information. That is, in the ECM system, after the received image information is demodulated by the modem 3, the received image information is stored in the ECM buffer 5, and the image information in the ECM buffer 5 is transferred to the encoding / decoding unit 9 to be decoded. One page is decomposed into a plurality of frames to check whether image information has been normally received. Upon successful reception, the decoded image information is set in the line buffer 6 and
The image information that is not decoded by the encoding / decoding unit 9 in the document storage unit 7 or the image information decoded by the encoding / decoding unit 9 and then encoded by the encoding / decoding unit 9 again Store information. Next, when one or more lines of image information are accumulated in the line buffer 6, the line buffer 6
When one or more pages of image information are stored in the page memory 8, the image information is transferred to the plotter 12, and the plotter 12 records the image information on recording paper. On the other hand, when there is a frame that is not normally received, the transmitting side retransmits the frame. Now, as shown by ER in FIG. 4, if an error occurs in the plotter 12 while receiving the third page, the facsimile apparatus 1 is in the alternate reception mode,
The signal is transmitted, and the receiving operation is continued.

In this way, in the proxy reception mode, even if an error occurs in the plotter 12 during reception, reception continues, and pages subsequent to the page where the error occurred in the plotter 12 are proxy-received and stored in the document storage unit 7. I do. In this case, the normal facsimile apparatus records the image information stored in the document storage means again from the first page even if the mode is switched to the alternate reception during the reception. However, since the facsimile apparatus 1 is provided with the normally-recorded page detecting means according to the fourth aspect, the image information of the normally-recorded page is deleted from the document storage unit 7 and is not re-recorded. Therefore, the recording paper 33 can be saved, and the operation of organizing the recorded recording paper 33 can be performed easily and without error.

Next, processing in the alternate reception inhibition mode will be described.

First, a description will be given of a process in the alternate reception prohibition mode by the normal facsimile communication system not based on the ECM system.

FIG. 5 is a sequence diagram in an alternate reception prohibition mode by a normal facsimile communication system not based on the ECM system. In the case of this system, the facsimile apparatus 1 receives a signal from the transmission side facsimile apparatus similarly to the case of FIG. Is received, a normal facsimile control signal is exchanged with the facsimile apparatus of the other party to start receiving image information. Plotter
When no error occurs at 12, the received image information is transferred to the modem 3, the FIFO memory 4, the line buffer 6, the page memory 8, and the plotter 12 as in the case of FIG. At the same time, the encoded image information is stored in the document storage unit 7. When the recording of all pages is completed normally, the image information in the document storage unit 7 is deleted.

However, if an error occurs in the plotter 12 during the reception, for example, during the reception of the image information of the third page as indicated by ER in FIG. 5, the facsimile apparatus 1 is in the alternate reception inhibition mode, (Procedure interruption negation signal) is output. At this time, assuming that the alternative facsimile apparatus simply sets the alternate reception prohibition mode, all image information in the page memory 8 and the document storage unit 7 is deleted because the alternate reception prohibition mode is set. As a result, the first page is
As shown in FIG. 5, the recording page is recorded and output during the reception of the second page, and although the image information of the second page is deleted from the page memory 8 and the document storage unit 7, Since the MCF signal has already been transmitted, the image is not retransmitted from the transmitting facsimile machine, and the image information of the second page is lost.

Therefore, according to the second aspect of the present invention, if an error occurs in the plotter 12 on the third page, the image information on the third page is retransmitted from the transmitting side, so that the document storage unit 7 and the page memory However, since the MCF signal is transmitted for the first page and the second page, they are stored in the document storage unit 7 and the page memory 8 without being deleted. Thereafter, when the plotter 12 returns, the facsimile machine 1 reads out the image information (the image information of the first page and the second page in the present embodiment) of the page to which the MCF signal has been transmitted from the document storage unit 7 and records the image information. Then, the image information of the third and subsequent pages retransmitted from the transmitting facsimile apparatus is received, and the plotter 12 records and outputs the image information. Therefore, without losing the image information already sent to MCF,
Recording and output can be performed, and the alternate reception prohibition mode can be set without causing loss of image information. As a result, the security can be improved by protecting the document, and it is also possible to prohibit the alternate reception of unknown destination, thereby reducing the communication cost.

According to the fourth aspect of the invention, if an error occurs in the plotter 12 on the third page, the image information on the third page is retransmitted from the transmission side in the same manner as in the second aspect of the invention. Before the PIN signal is sent, the image information is deleted from the document storage unit 7 and the page memory 8, but the image information of the first page and the second page is deleted from the document storage unit 7 and the page memory 8 depending on whether the image information is normally recorded and output. Have decided. That is, even if the image information is not normally recorded and output by the plotter 12 even if the MCF signal is normally received and the MCF signal is output, the image information is stored in the document storage unit 7 without being deleted. The system controller 10 determines whether or not the normal recording has been performed, based on the detection results of the document sensors 34 and 35 shown in FIG. That is, as shown in FIG. 6, when the image information of the first page is received, the image information is transferred from the page memory 8 to the plotter 12 and writing to the photosensitive belt 23 is started. At the same time, the recording paper 33 is conveyed by the feed roller 31. At this time, the recording paper sensor 34 detects the leading end of the recording paper 33, and measures the timing with the image written on the photosensitive belt 23. The recording is performed by driving the feed roller 31. Thereafter, when the recording paper sensor 34 detects the rear end of the recording paper 33,
Recording is completed in a predetermined time, and the recording paper sensor 35
Detects the trailing end of the recording paper 33, the recording paper 33 is discharged in a predetermined time. Therefore, in the case of FIG. 5, the first page and the second page are normally received, and during the reception of the second page, 1
Since the page is normally recorded, the image information of the first page is deleted from the document storage unit 7. However, since the image information of the second page is not normally recorded, the image information is stored without being deleted from the document storage unit 7. Keep it. Thereafter, when the plotter 12 returns, the facsimile apparatus 1 sets the image information of the page that has not been normally recorded in the image information of the page to which the MCF signal has been sent from the document storage unit 7 (the image information of the second page in this embodiment). Is read out and recorded and output by the plotter 12, and the image information of the third and subsequent pages retransmitted from the transmitting facsimile apparatus is received and recorded and output by the plotter 12. Therefore, it is possible to record and output the image information that has already been transmitted to the MCF without losing the image information, and to prevent double recording of the image information of a page that has already been normally recorded. The setting can be performed without causing a loss of information and without performing double recording. As a result, it is possible to save the recording paper while protecting the document and improving the security, and it is also possible to prohibit the alternate reception of an unknown destination, thereby reducing the communication cost.

Next, processing in the alternate reception prohibited mode in the facsimile communication method using the ECM method will be described.

FIG. 7 is a sequence diagram in the alternate reception prohibition mode in the facsimile communication system by the ECM system. In this system, the facsimile apparatus 1 transmits a call from the transmitting facsimile apparatus in the same manner as in FIG. If there is, a facsimile control signal is exchanged with the partner facsimile apparatus by the ECM method to start receiving image information. When no error occurs in the plotter 12, the facsimile apparatus 1 transfers the received image information to the modem 3, the ECM buffer memory 5, the line buffer 6, the page memory 8, and the like as in the case of FIG.
The document image is transferred to the plotter 12 and recorded on the recording paper 33, and the encoded image information is stored in the document storage unit 7.

When the recording of all pages is completed normally, the image information in the document storage unit 7 is deleted.

On the other hand, during reception, for example, as indicated by ER in FIG.
If an error occurs in the plotter 12 during the reception of the third page, the facsimile machine 1 sends out a DCN signal to interrupt the communication, and stores and records the image information in the document storage unit 7 as in the case where the ECM method is not used. Perform output processing. That is,
According to the second aspect of the present invention, the image information of all pages to which the MCF signal has been transmitted is stored in the document storage unit 7,
When 12 is restored, it is read from the document storage unit 7 and recorded and output. According to the fourth aspect of the present invention, the image information of the normally recorded page out of the image information of the page to which the MCF signal is transmitted is deleted from the document storage unit 7 to prevent double recording.

The reception and recording processing in the facsimile apparatus 1 can be shown as a flowchart in FIG.

That is, when the facsimile machine 1 receives the post message, it checks whether or not the memory is being received (step S1). If the memory is not being received, the facsimile machine 1 checks whether or not it is in the discharged page erasing mode (step S2). The discharged page erasing mode is a process corresponding to the fourth aspect of the present invention. When the mode is not the discharge page erasing mode, it is checked whether the plotter 12 is normal (step S3). If the mode is normal, the MCF signal is set, a post message response is sent, and the process returns to step S1 (steps S4, S5). If an error has occurred in the plotter 12 in step S3, it is checked whether there is free space in the document storage unit 7 (step S3).
S6) If there is an empty capacity, it is checked whether the mode is the alternate reception prohibition mode (step S7). When the mode is not the interception reception inhibition mode, the memory is set and the MCF signal is set and the response of the post message is transmitted (steps S8, S4,
S5). In step S7, when the alternate reception inhibition mode is set, PI
The N signal or the DCN signal is set and a post message response is transmitted (steps S9 and S5). And step
If there is no free space in the document storage unit 7 in S6, a PIN signal or a DCN signal is set and a post message response is sent. Therefore, in the alternate reception prohibited mode,
Even if an error occurs in the plotter 12, the image information of the received document normally received before the error can be stored in the document storage unit 7, and the stored image information is recorded when the plotter 12 returns. be able to.

In step S2, if the discharge page erasing mode is set, it is checked whether there is a discharge page (step S10). If there is a discharge page, the image information of the discharge page is stored in the document storage unit 7. Then, the process proceeds to step S3 (step S11) to check whether the plotter 12 is normal.

Therefore, the image information of the page normally received and normally recorded and output can be deleted from the document storage unit 7, so that the document storage unit 7 can be used effectively and double recording can be prevented. can do.

(Effect) According to the first and second aspects of the present invention, in a document receiving apparatus provided with a non-real-time recording apparatus, when a non-real-time recording apparatus error is detected during reception of a document, a predetermined control signal is transmitted to the partner communication terminal. To notify the other communication terminal that an error has occurred in the page being received, and then interrupt the communication, and copy the document normally received and stored in the document storage unit before the error occurs. The invention according to claims 3 and 4, wherein the data can be recorded and output after the restoration, so that the alternate reception prohibition mode in which the document of the normally received page can be effectively used can be set, and the communication cost can be reduced. According to this, when an error occurs in the non-real-time recording unit during the reception of a document, a predetermined control signal is output to the partner communication terminal to display an error on the page being received. After notifying the other communication terminal that the error occurred, the communication was interrupted, and a control signal indicating that the communication was normally received before the occurrence of the error was transmitted, and the document stored in the document storage unit was normally recorded by the recording unit. The determined page can be erased from the document storage means, and the received document of the page stored in the document storage means can be recorded and output after the recovery of the recording means, so that the document of the normally received page is valid. It is possible to set an alternate reception prohibition mode that can be used, reduce communication costs, and further prevent double recording and reduce waste of recording paper.

A receiving step of receiving image information while transmitting the control signal to the other party's communication terminal; a first storing step of storing the received image information for a plurality of pages in an encoded state; A second storage step of storing the decoded image information after decoding, and an output step of outputting the received image information to the output unit after the completion of the image information reception of at least the entire page currently receiving the received image information. When an error of the output unit is detected while receiving the image information,
After outputting and notifying a second control signal indicating that an error has occurred to the partner communication terminal, the communication is interrupted,
A document receiving and outputting method in which the first control signal is normally transmitted before an error occurs in the first storing step and the image information of the stored page is output after the output unit is restored. . 2. A first indicating whether or not each page has been normally received.
Receiving means for receiving image information while transmitting the control signal to the other party's communication terminal; first storage means capable of storing the received image information for a plurality of pages in an encoded state; And decoding means for storing the received image information stored in the second storage means, and outputting the page after completion of image information reception of at least the entire page being received. If an error of the output means is detected while receiving the image information,
After outputting and notifying a second control signal indicating that an error has occurred to the other communication terminal, the communication is interrupted, and the output unit outputs the error stored in the first storage unit after the error is recovered. A document receiving and outputting device which receives a normal control signal before the occurrence of the message, outputs a first control signal, and outputs image information of a stored page. 3. A first indicating whether or not the page has been normally received for each page.
Receiving the image information while transmitting the control signal to the other communication terminal, and storing and holding the received image information, so that the page is output to the output unit at least after the completion of the image information reception of the entire page being received. An output method, comprising: an error detection step of detecting an error of the output unit; and a normal output page detection step of detecting a page of image information normally output by the output unit. When an error of the output means is detected,
A second control signal indicating that an error has occurred is output to the other communication terminal to notify the other communication terminal, and after notifying the normally received image information page information, the communication is interrupted. 1 of the image information to which the control signal of No. 1 is transmitted and stored and erased, the page determined to have been normally output by the normal output page detection step is erased, and the page before output stored and held after the output unit is restored. Receiving and outputting the received image information. 4. A first indicating whether or not each page has been normally received.
Receiving means for receiving the image information while transmitting the control signal to the partner communication terminal, image information storing means for storing and holding the received image information, and at least receiving image information stored and held in the image information storing means. An output unit that outputs the page after completion of image information reception of the entire page being received, comprising: an error detection unit that detects an error of the output unit; and a normal operation by the output unit. Normal output page detecting means for detecting a page of the output image information, and when the error detecting means detects an error during reception of the image information, a second control signal indicating that an error has occurred is received. After outputting the notification to the communication terminal and notifying the image information page information that has been normally received, the communication is interrupted, and the first control signal is normally received before the occurrence of an error and the first control signal is transmitted and stored. Of the output image information, the page determined to be output normally by the normal output page detection unit is deleted, and the output unit receives the page before output stored in the image information storage unit after error recovery. A document receiving and outputting device for outputting image information.
