A cutter drive unit 4d that controls the drive of the cutter 4c is provided, and the image data sent via the system bus 7 is printed on recording paper, cut for each page, and discharged.

The reading unit 5 reads an image on a document as a video signal at a predetermined resolution, corrects the video signal as video data, and converts each pixel signal of the video data into digital data. The digital data is a modem 1a which is an interface circuit to the communication network.
Then, the image data is transmitted by facsimile to the destination facsimile machine by the NCU 1 according to a predetermined transmission procedure.

The data storage unit 6 is a memory that temporarily stores and holds the image data received by facsimile via the communication network and the image data read from the document by the reading unit 3. Further, the data storage unit 6 has an ECM buffer as an area for accumulating the received image data in the error correction mode.

That is, the CPU 2 prohibits the cutter driving unit 4d from driving the cutter 4c while receiving the image data, and causes the cutter driving unit 4d to drive the cutter 4c in the inter-page communication procedure of the image data. Means and
It functions as a unit that prohibits the cutter driving unit 4d from driving the cutter 4c at the start of transmission / reception of the image data and permits the cutter driving unit 4d to drive the cutter 4c after the end of transmission / reception of the image data. The printing unit 4b of the recording unit 4 also functions as a unit that prints a cut line between pages of image data to be printed while the cutter 4c is prohibited from being driven.

It also fulfills the function of a means for driving.

Next, the data transmission procedure in the facsimile will be described. FIG. 2 is an explanatory diagram showing an example of a data transmission procedure in the facsimile apparatus, in which data from the calling side facsimile apparatus (calling terminal) Tx to the called side facsimile apparatus (called terminal) Rx is shown. The transmission procedure will be described. The abbreviations in the figure are CCIT
These are terms defined by the T recommendation, and detailed explanations thereof are omitted.

First, the calling terminal Tx sends a calling signal (CNG).
, The called terminal Rx receives the CNG, returns a called terminal identification signal (CED), and then returns a digital identification signal (DIS). There are also cases where an optional non-standard function identification signal (NSF) and a called terminal identification signal (CSI) are returned together with DIS.

Thereafter, the calling terminal Tx transmits a digital command signal (DCS) and then a training check signal (TCF). The called terminal Rx to NSF
And CSI are returned, a non-standard function setting signal (NSS) and a transmitting terminal identification signal (TSI) are transmitted before DCS transmission. Then, the called terminal Rx receives the training check signal, performs the training check, and returns the reception preparation confirmation signal (CFR) when the adjustment of the modem is completed.

Upon receiving the CFR, the calling terminal Tx receives 1
Image data PIX-P. 1 and multi-page signals PPS / MPS are transmitted. The called terminal Rx receives the image data PIX-P. 1 is returned, the partial page request signal PPR is returned, and in this case, the image data PIX-P.P. Return the resend request of 1.

Upon receiving the PPR, the calling terminal Tx receives the request page, in this case, the image data PIX-P.
After sending 1 again, the multi-page signal PPS / MPS
Send The called terminal Rx receives the retransmitted image data PIX-P. If 1 is not inconvenient, the message confirmation signal MCF is returned. In this manner, the image data PIX is sequentially transmitted page by page from the calling terminal Tx to the called terminal Rx.

Then, the calling terminal Tx receives the image data PIX-P. When n is transmitted and the procedure end signal PPS / EOP which is the final page signal is transmitted, the called terminal R
If there is any inconvenience in receiving the image data, x returns a partial page request signal and requests retransmission, but if there is no inconvenience, it returns a message confirmation signal MCF. Calling terminal T
When x receives the MCF for the image data of the last page, it sends a line disconnection command signal DCN to disconnect the line,
This data transmission ends.

In this way, the facsimile apparatus can print the image data received by the facsimile and send the image data read from the original by facsimile. Also, dual access communication can be performed in which image data read from a document is transmitted by facsimile while the image data received by facsimile is printed out. further,
It can also function as an error correction mode that prints image data while receiving it by facsimile.

Next, processing of image data printing operation and cutter drive control operation in this facsimile apparatus will be described. FIG. 3 is a diagram showing a processing procedure of cutter drive control during facsimile reception printing. First, the called terminal Rx
When receiving and printing image data by facsimile,
The communication state at the time of the reception is monitored, the driving of the cutter 4c is prohibited during the reception of the image data, and the cutter 4c is driven by the communication procedure between the pages of the image data.

As shown in FIG. 3, when the called terminal Rx finishes printing (recording) one page of image data and is receiving a facsimile of the image data from the calling terminal Tx, the cutter driving is prohibited. Then, the cutter is driven in the communication procedure after the end of the image data reception. That is, T in the figure
The cutter drive is prohibited during the period of 1 and T3, and the communication procedure period T
When 2, the cutter drive is enabled and the printed recording paper is cut.

In this way, the cutter driving is prohibited during the reception of the image data to prevent the noise from being generated, and the data bus is prevented from having the noise, thereby preventing the noise from affecting the image data. be able to. Further, the state of the modem in the communication procedure is in the low speed mode unlike the state in which the image data is being transmitted, and since there is little trouble due to noise or the like, there is almost no influence on the data exchanged in the communication procedure.

Therefore, in the facsimile apparatus of this embodiment, the image data being received can be prevented from being adversely affected by the noise generated by the cutter driving, and the image data can be received in a good condition.

In the called terminal Rx, the driving of the cutter 4c may be prohibited at the start of transmission / reception of the image data, and the driving of the cutter 4c may be permitted after the transmission / reception of the image data is completed. In this case, the called terminal Rx prohibits the cutter drive at the same time as the facsimile transmission operation starts, does not cut the recording paper of the image data currently being printed, and waits the cutter drive until the facsimile transmission is completed. After the facsimile transmission is completed, the cutter 4c is driven to cut the recording paper on which the image data is printed.

Further, when the facsimile receiving and printing operation is started, the cutter driving is prohibited and the recording paper is not cut.
Even if the facsimile reception is completed, if the facsimile transmission is being performed on the other hand, the cutter drive is made to wait until the facsimile transmission is completed, and after the facsimile transmission is completed, the cutter 4c is driven to print the recording paper on which the image data is printed. Make a disconnection.

In this way, in the dual access operation of facsimile transmission during the printing operation of the image data, the cutter driving of the recording unit 4 is stopped and made to stand by at the time when the communication is started. The influence on the data can be prevented.

In this way, during dual access operation in which facsimile transmission is performed during facsimile reception printing or facsimile reception printing is performed during facsimile transmission, the image data being transmitted / received is not adversely affected by noise generated by the cutter drive. The image data can be transmitted and received in a good condition. Also,
Since it is only necessary to prohibit the cutter drive during communication, it is possible to simplify the cutter drive control and significantly reduce the processing load on the CPU 2 and the cutter drive unit 4d.

Further, by prohibiting the cutter drive during facsimile transmission / reception so that the printing operation does not stand by during that period, a cutoff line is provided between pages of image data to be printed while the drive of the cutter 4c is prohibited. Can be printed. In that case, the printing operation is continued even when the cutter drive is prohibited, and a cutoff line is printed between each page to print a plurality of pieces of image data. After printing the last page, the end of communication is detected and the cut drive is performed to cut the recording paper.

That is, even if a cutter is provided, the received image data is printed, the cutter operation between the pages is also prohibited, and a cutoff line is printed between each page of the recording paper to receive the image data. It is possible to avoid the influence of noise generated by the cutter driving on the image data. If the cutter is driven for each communication to cut the recording paper, the recording order for each communication can be easily identified.

In this way, it is possible to prevent the image data being transmitted / received from being adversely affected by noise generated by the cutter drive, and during the transmission / reception of image data, the printing operation is continued without being stopped halfway. Since it can be performed, the image data can be printed efficiently without degrading the image quality. In addition, the recording paper after printing can be cut into individual pages for easy sorting.

Even when the image data that has already been received is printed and transmitted by facsimile, or when the image data received while the image data to be transmitted by facsimile is being stored is printed, the cutter drive is prohibited during communication. Prevent the generation of noise so that the image data is not affected.

Next, the cutter drive control process when the image data received by the facsimile apparatus of this embodiment is temporarily stored in the data storage unit 6 and then printed will be described. In this case, the called terminal Rx causes the data storage unit 6 to print the stored image data when the data storage unit 6 stores a predetermined amount or more of image data.

That is, the called terminal Rx stores all the image data received by facsimile in the data storage unit 6,
It is sequentially read and printed by the recording unit 4, and the recording paper after printing is cut page by page by the cutter 4c and discharged. Further, when a predetermined amount or more of image data is stored in the data storage unit 6, the stored image data in the data storage unit 6 is printed.

The above-mentioned predetermined amount should be set to a value such that when printing the already stored image data to reduce the storage amount in the data storage unit 6, there is sufficient capacity to store the image data to be transmitted by facsimile. In this case, the process of reducing the amount of data stored in the data storage unit 6 will not be in time, and communication failure will not occur due to memory over.

FIG. 4 is a flow chart showing a cutter drive control process when printing is carried out after all the image data to be transmitted by facsimile are stored in the memory. In this process, in step (indicated by "S" in the figure) 1, it is determined whether or not the image data is received. If it is larger than the default value, the process proceeds to step 3, the image data of the next page is accumulated, and the process returns to the first process.

If the memory capacity of the data storage unit is equal to or smaller than the predetermined value in the judgment of step 2, the process proceeds to step 5 to print the image data for one page which has already been stored, and step 6
Then, it proceeds to step 7 to judge whether or not the image data is being received. If it is not being received, the processing goes to step 7 to drive the cutter to cut the recording paper and return to the first processing.

If it is determined in step 1 that the image data is not received, the process proceeds to step 4 to determine whether or not there is image data stored in the data storage unit. If there is no image data, the first process is performed. However, if the image data to be printed is accumulated, the process proceeds to step 5 to print the image data for one page, and if it is determined in step 6 that the image data is not being received, the recording paper is printed in step 7. Disconnect.

After that, similarly, the image data accumulated in the data storage unit is printed page by page, the recording paper is cut, and when the printing of all the pages of the accumulated image data is completed, this processing is performed. To finish. The default value of the data capacity corresponds to a predetermined amount for determining whether or not to print the accumulated image data, and here, the image data of one page (maximum recording paper length of maximum linear density) Has a storage capacity.

That is, in this process, when facsimile reception is started, the storage memory capacity is checked for each page of the received image data, and if it can be stored, the image data of that page is stored. Then, when there is a sufficient memory capacity until the end of one facsimile reception, the image data of all pages is accumulated, the accumulated image data is printed in order, and the cutter is driven every time one page of image data is printed. To cut the recording paper.

When the memory capacity is insufficient,
The image data accumulated so far is sequentially printed, and the cutter drive for each page is not performed until the end of facsimile reception, but is performed after the image data reception process.

As described above, after all the image data received by the facsimile is stored in the data storage unit 6, the printing of the image data is started and the cutter is driven. Therefore, noise generated by the cutter driving for the image data being received by the facsimile is generated. Is not affected.

Further, when the image data of a predetermined amount or more is accumulated in the data storage unit 6, the accumulated image data is printed. Therefore, when the memory capacity becomes insufficient during the accumulation of the image data, the accumulation operation is performed. Since the previously stored image data is printed while reducing the storage amount in the memory, it is possible to avoid a situation where communication is not established due to memory over before reception is completed.

Further, if the memory for accumulating the received image data has accumulated a predetermined amount or more of the image data, the accumulated image data is printed so that the cutter is not driven during the reception of the image data. It is possible to prevent the image data being received from being adversely affected by noise generated by the cutter driving.

Further, when the memory capacity becomes insufficient during the storage of the image data, the image data stored earlier is printed while performing the storage operation to reduce the storage amount of the memory, and the memory is over before the reception is completed. It is possible to avoid a state where communication is not established due to.

Next, in the facsimile apparatus of this embodiment, when the reception timing and the printing timing of the image data are shifted at the same time, that is, the error correction mode (ECM) for printing the sequentially received image data while receiving the image data. The cutter drive control process at the time will be described.

In this case, the called terminal Rx drives the cutter 4c when printing the image data received in the error correction mode and when receiving the image data of another page when the printing of the image data of one page is completed. To wait,
After receiving the image data of another page, the cutter 4c is driven.

The called terminal Rx stores the image data received at the time of ECM in the ECM buffer of the data storage unit 6, and while the image data of one page is being printed by the recording unit 4, the image data of the next page and the subsequent pages are transmitted by the communication procedure. To receive. And 1
Even if the printing of the image data of the page is completed, if the image data of the next page and thereafter is being received, the cutter 4c is made to wait for driving, and when the reception of the image data is completed, the cutter 4c is driven to cut the recording paper. To do.

FIG. 5 is a diagram showing a processing procedure of cutter drive control during facsimile reception printing by ECM. As shown in the figure, when the called terminal Rx finishes printing (recording) the image data of the first page, the calling terminal Rx sends 2
When the image data of the second page is being received by facsimile, the cutter drive is put on standby, and the cutter is driven in the communication procedure after the completion of the reception of the image data of the second page.

That is, during the period T4 in the figure, the cutter drive is put on standby, and when the multi-page signal MPS in the communication procedure is received after the image data of the second page is received, the cutter drive is enabled. Then, during the period T5 from the reception of the MPS to the start of the reception of the next page, the cutter 4c
To cut the printed recording paper.

As described above, when printing of one page of the image data received by the ECM is completed, when the image data of the next page and subsequent pages are being received, the cutter for cutting the recording paper is kept waiting, and the image data Since the cutter is driven after the reception is completed, noise is not generated due to the cutter driving while the image data is being received by the ECM, and the noise does not affect the image data being received on the data bus. Image data can be received and printed in good condition.

If a memory for accumulating image data is provided even in the case of the non-ECM in the above embodiment, the received image data is sequentially received while receiving the image data in the same manner as in the case of the ECM described above. By printing and controlling the cutter drive at the time of printing, it is possible to prevent the influence of noise generated by the cutter drive on the image data during communication.

[0064]

As described above, according to the communication apparatus of the present invention, the cutter for cutting the recording paper in page units is not driven during the image data communication, so that the image data being communicated is cut by the cutter. It is possible to prevent the noise generated during driving from being adversely affected.
