According to the first and second aspects of the invention having the above-described structure, the recording sheets are sorted and recorded and output in the correct order as long as the recording and outputting are performed in the same order as in the normal receiving operation. It is not necessary to use the memory on the receiving side.

Further, according to the invention of claim 3 having the above-mentioned structure, the recording paper is sorted in the correct order as long as the recording output is carried out in the order received in the same manner as the normal receiving operation without using the memory on the receiving side. Of course, the output order of the images is switched according to the recording type of the receiving side, so that the sending order may be unnecessarily switched to the receiving side that does not need to change the image sending order. You can prevent this.

Further, according to the invention of claim 4 having the above-mentioned structure, since the operator is notified of the recording type on the receiving side before the transmission, the operator can appropriately change the order of the originals and insert the originals in response to the notification. This allows the recording sheets to be sorted and recorded and output in the correct order on the receiving side without using a memory for transmission and reception.

According to the invention of claim 5 having the above-mentioned structure, the recording papers are sorted in the correct order as long as the recording output is performed in the same order as in the normal receiving operation without using the memory on the receiving side. Of course, since the header attached to the first page of the fax transmission is sent, even if an error occurs during communication and the transmission is not completed, the sender will send it from anywhere. You can easily recognize what has been done.

Further, in the invention of the sixth aspect having the above-mentioned structure, the recording sheets are sorted in the correct order as long as the recording output is performed in the same order as the normal receiving operation without using the memory on the receiving side. Of course, due to the operator switching, the header attached to the first page of the fax transmission will be sent first to the destination where a communication error is likely to occur, so an error will occur during communication. Even when the transmission is not completed, the receiving side can easily recognize where the transmission is from.

nly Memory), RAM (Random Access Memory), etc., and controls the main body of the facsimile apparatus according to a program in the ROM. The image memory 2 stores an image read by the image reading unit 6 or an image received via a line. The operation display unit 3 includes a start button, a stop button, various operation keys necessary for operating the facsimile apparatus such as a numeric keypad and a one-touch key, and a display device that displays a setting state of various modes and a message for operation guidance. Become.

The image reading section 4 reads an image of a document at a predetermined resolution, and the image recording section 5 records an image on a recording sheet at a predetermined resolution. The network control unit 6 detects incoming / closed calls from the line network and executes line control. The modem 7 is for modulating or demodulating an image signal transmitted and received via a line.
The encoding / decoding unit 8 encodes and compresses the image read by the image reading unit 4, and decodes and expands the image received via the network control unit 6. The communication control section 9 executes a predetermined communication procedure with the facsimile machine of the other party via the line. Then, these, the system control unit 1, the image memory 2, the operation display unit 3,
The image reading unit 4, the image recording unit 5, the network control unit 6, the modem 7,
The encoding / decoding unit 8 and the communication control unit 9 exchange data via a bus line.

Next, the transmission operation in the first embodiment of the present invention will be described with reference to the flowchart of FIG.
Step 1 is a step of determining whether or not a document is inserted in a document table (not shown). When the manuscript is inserted by the operator (Yes in step 1), the system control unit 1 outputs a message prompting the input of the destination number, for example, "Please input the destination number", etc., on the display unit of the operation display unit 3. Let When the destination number is input via the ten keys on the operation display unit 3 (step 2),
The system control unit 1 uses the input destination number as an internal RA
Temporarily store in M. If no input is made for a predetermined period of time even though the message prompting the input of the destination number is displayed and output, a buzzer or the like is sounded to give a warning to the operator.

When the storage of the input destination number is completed,
The system control unit 1 causes the display device to display and output a message asking whether to transmit the image from the first page or the last page. Here, when the transmission mode for transmitting the image from the last page is selected (Y in step 3)
es), the flag for the transmission mode in the RAM is turned on (step 4). On the other hand, if the transmission mode for transmitting the image from the first page is selected (No in step 3), R
The flag for the transmit mode in the AM remains off.

In step 5, the inserted document is conveyed to the image reading section 4 by a conveyance roller (not shown) and is read at a predetermined resolution. The image read by the image reading unit 4 is encoded by the encoding / decoding unit 7, and then the encoded image is sequentially transferred and accumulated in the image memory 2. At this time, the system control unit 1 recognizes, for each page, at which address of the image memory 2 the image is stored, and stores and manages the image in a predetermined area in the RAM. When all the images are stored in the image memory 2, the system control unit 1 reads the destination number stored in the RAM and makes a call (step 7).

After the call is made, when the communication control unit 9 detects that the line is closed, a predetermined pre-communication procedure is executed via the network control unit 6. At the same time, the system control unit 1 detects the state of the flag for the transmission mode in the RAM, and when the flag is on (Yes in step 8), the last page is transmitted so that the image is transmitted from the last page. The image is read out by sequentially designating from the address of, and the read image is transmitted to the receiving side through the line (step 9). When the image transmission is completed (Yes in step 10), the network control unit 6
A communication end procedure is executed via the to open the line.

On the other hand, when the detected flag for the transmission mode is off (No in step 8), the system control section 1 sequentially designates from the address of the first page as in the case of normal transmission. The image is read, and the read image is transmitted to the receiving side via the line (step 11). When the image transmission is completed (Yes in step 12)
s), the communication termination procedure is executed via the network control unit 6 to open the line. In this way, on the receiving side, the recording paper is sorted and recorded and output in the correct order as long as it is recorded and output in the same order as in the normal reception operation, so there is no need to use a memory for sorting. It is possible to avoid reception refusal due to memory over.

Next, the transmission operation in the second embodiment of the present invention will be described with reference to the flowchart of FIG.
In the second embodiment, the recording type of the receiver, that is, a method of recording on roll paper or recording on cut paper, is performed through a predetermined bit of the NSF signal sent from the receiving side in the pre-communication procedure. The method to be used shall be notified. Step 21 is a step of determining whether or not a document is inserted in a document table (not shown). When the manuscript is inserted by the operator (Yes in step 21)
s), the system control unit 1 causes the display of the operation display unit 3 to display and output a message prompting the input of the destination number, for example, “Please input the destination number”. Then, when the destination number is input via the ten keys of the operation display unit 3 (step 22), the system control unit 1 temporarily stores the input destination number in the internal RAM. If no input is made for a predetermined period of time even though the message prompting the input of the destination number is displayed and output, a buzzer or the like is sounded to give a warning to the operator.

In step 23, the inserted document is conveyed to the image reading section 4 by a conveyance roller (not shown) and read at a predetermined resolution. The image read by the image reading unit 4 is encoded by the encoding / decoding unit 7, and then the encoded image is sequentially transferred and accumulated in the image memory 2 (step 24). At this time, the system control unit 1 recognizes at which address of the image memory 2 the image is stored page by page and stores it in a predetermined area in the RAM.

When all the images are stored in the image memory 2,
The system controller 1 reads out the destination number stored in the RAM and makes a call (step 25). After the call is made, when the communication controller 9 detects that the line is closed, a predetermined pre-communication procedure is executed via the network controller 6. At this time, the system control unit 1 analyzes the NSF signal sent from the receiver in the pre-communication procedure, and determines the recording type of the receiver, that is,
It is judged whether it is a method of recording on roll paper or a method of recording on cut paper (step 26). If it is determined in step 26 that the receiver is a system for recording on roll paper (No in step 26), the system control unit 1 designates in order from the address of the first page as in the case of normal transmission. Then, the image is read out and the read image is transmitted to the receiving side through the line (step 29). Then, when the transmission of the image is completed (Yes in step 30), a communication termination procedure is executed through the network control unit 6 to open the line.

On the other hand, if it is determined in step 26 that the receiver is a system for recording on cut paper (Yes in step 26), the image of the last page is transmitted from the address of the last page in order to transmit the image from the last page. The images are designated and read in order, and the read images are transmitted to the receiving side via the line (step 27). Then, when the transmission of the image is completed (Yes in step 28), a communication end procedure is executed through the network control unit 6 to open the line. In this way, on the receiving side, the recording paper is sorted and recorded and output in the correct order as long as the recording output is performed in the same order as in the normal receiving operation without using the memory. Since the transmission order of the images can be switched appropriately according to the recording type, it is possible to prevent the transmission order from being unnecessarily switched to a receiver that does not need to change the transmission order of the images. This is because, in the case of the method of recording on roll paper (without cutting) on the receiving side, it is more convenient to record and output from the first page.

Next, the transmission operation in the third embodiment of the present invention will be described with reference to the flowchart of FIG.
Also in the third embodiment, the recording type of the receiver, that is, the recording method on the roll paper or the recording on the cut paper, is performed through the predetermined bit of the NSF signal sent from the receiving side in the pre-communication procedure. The method to be used shall be notified. When the destination is designated via the one-touch key of the operation display unit 3 (step 41), the system control unit 1
Information such as the destination name, destination number, and recording type of the receiver registered in association with the one-touch key is read out and displayed on the display of the operation display unit 3 (step 42). After that, when the operator inserts a document (Yes in step 43), the system control unit 1 prompts a message, for example, "please press the start key."
And the like are displayed and output by the display unit of the operation display unit 3. still,
If no input is made for a predetermined time despite the display and output of the message prompting transmission, a buzzer or the like is sounded to give a warning to the operator.

When the start key of the operation display section 3 is pressed, the system control section 1 calls the destination designated by the one-touch key (step 44). After calling, communication control unit 9
When it is detected that the line is closed, a predetermined pre-communication procedure is executed via the network control unit 6. At this time, the system control unit 1 sends the NS sent from the receiver in the pre-communication procedure.
The F signal is analyzed to extract the destination name and the recording type of the receiver, and these pieces of information are registered in association with the selected one-touch key (step 45).

After that, the system control section 1 drives a conveyance roller (not shown) to convey the inserted document to the image reading section 4 and read the image. The image read by the image reading unit 4 is encoded by the encoding / decoding unit 7 and transmitted to the receiving side via the line (step 47). When the transmission of the image is completed (Yes in step 28), the communication end procedure is executed through the network control unit 6 to open the line. In this way, since the recording type on the receiving side is notified to the operator before transmission, the operator may change the order of the originals as appropriate based on this notification and insert the originals. The recording sheets are sorted and printed out in the correct order without being used.

Next, the transmission operation in the fourth embodiment of the present invention will be described with reference to the flowchart of FIG.
Step 51 is a step of determining whether or not a document is inserted in a document table (not shown). When the manuscript is inserted by the operator (Yes in step 51), the system control unit 1 outputs a message prompting the input of the destination number, for example, "Please input the destination number", by the display unit of the operation display unit 3. Let Then, when the destination number is input through the ten keys of the operation display unit 3 (step 5
2), the system control unit 1 temporarily stores the input destination number in the internal RAM. If no input is made for a predetermined period of time even though the message prompting the input of the destination number is displayed and output, a buzzer or the like is sounded to give a warning to the operator.

In step 53, the inserted document is conveyed to the image reading section 4 by a conveyance roller (not shown) and is read at a predetermined resolution. The image read by the image reading unit 4 is encoded by the encoding / decoding unit 7, and then the encoded image is sequentially transferred and accumulated in the image memory 2 (step 54). At this time, the system control unit 1 recognizes at which address of the image memory 2 the image is stored page by page and stores it in a predetermined area in the RAM.

When all the images are stored in the image memory 2,
The system controller 1 reads out the destination number stored in the RAM and makes a call (step 55). After the call is made, when the communication controller 9 detects that the line is closed, a predetermined pre-communication procedure is executed via the network controller 6. When the pre-communication procedure is completed, the system control unit 1 specifies the address of the first page to read the image, and transmits the read image to the receiving side via the line (step 56). Step 57
Is a step of determining whether or not the transmission of the image of the first page is completed. Here, when it is determined that the transmission of the image of the first page is completed (Yes in step 57), the process proceeds to step 58, and the system control unit 1 determines that the image of the last page should be transmitted next. The image is read out by sequentially designating from the page address, and the read image is transmitted to the receiving side through the line (step 58). Then, when the transmission of the images up to the second page is completed (Yes in step 59).
s), the communication termination procedure is executed via the network control unit 6 to open the line. In this way, on the receiving side, the recording sheets are sorted and recorded and output in the correct order as long as they are recorded and output in the same order as they are received in the same manner as the normal reception operation without using the memory. Since the header attached to the first page is transmitted, even if an error occurs during communication and the transmission is not completed, the receiving side can easily recognize where the transmission is from.
Further, it is effective that the contents of the received contents can be roughly grasped by looking at the image of the first page without using the FAX sending slip.

Next, the transmission operation in the fifth embodiment of the present invention will be described with reference to the flowchart of FIG.
Step 61 is a step of determining whether or not a document is inserted in a document table (not shown). When the manuscript is inserted by the operator (Yes in step 61), the system control unit 1 outputs a message prompting for the input of the destination number, for example, “Please input the destination number” on the display of the operation display unit 3. Let Then, when the destination number is input through the ten keys of the operation display unit 3 (step 6
2), the system control unit 1 temporarily stores the input destination number in the internal RAM. If no input is made for a predetermined period of time even though the message prompting the input of the destination number is displayed and output, a buzzer or the like is sounded to give a warning to the operator.

When the storage of the input destination number is completed,
The system control unit 1 causes the display device to display and output a message asking whether to transmit the image from the final page or to transmit from the final page after transmitting the header. If the transmission mode for transmitting the image from the last page is selected (Yes in step 63), the transmission mode flag in the RAM is turned on (step 64). On the other hand, when the transmission mode for transmitting from the last page after the header transmission is selected (No in step 63), the flag for the transmission mode in the RAM is kept off.

In step 65, the inserted document is conveyed to the image reading section 4 by a conveyance roller (not shown) and is read at a predetermined resolution. The image read by the image reading unit 4 is decoded by the encoding / decoding unit 7, and then the decoded image is sequentially transferred and accumulated in the image memory 2 (step 66). At this time, the system control unit 1 recognizes at which address of the image memory 2 the image is stored page by page and stores it in a predetermined area in the RAM. When all the images are stored in the image memory 2, the system control unit 1 reads the destination number stored in the RAM and makes a call (step 67). After the call is made, when the communication controller 9 detects that the line is closed, a predetermined pre-communication procedure is executed via the network controller 6. At the same time, the system control unit 1 detects the state of the transmission mode flag in the RAM, and if the flag is on (Yes in step 68), the last page is transmitted so that the image is transmitted from the last page. The image is read out by sequentially designating from the address of, and the read image is transmitted to the receiver side through the line (step 69). Then, when the transmission of the image is completed (Yes in step 70), the communication end procedure is executed through the network control unit 6 to open the line.

On the other hand, when it is detected that the flag for the transmission mode is off (No in step 68), the address of the first page is designated to read the image, and the image is read to the receiving side through the line. The image is transmitted (step 71).
Step 72 is a step of determining whether or not the transmission of the image of the first page is completed. When it is determined that the transmission of the image of the first page is completed (Yes in step 72),
Proceeding to step 73, the system control unit 1 reads out the image by sequentially designating from the address of the last page to transmit the image from the last page, and transmits the read image to the receiving side via the line. Then, when the transmission of the image up to the second page is completed (Yes in step 74), the communication end procedure is executed through the network control unit 6 to open the line.

In this way, on the receiving side, the recording sheets are sorted and recorded and output in the correct order as long as they are recorded and output in the same order as in the normal reception operation without using the memory. When the operator is switched, the header attached to the first page of the fax transmission will be sent first to the destination where a communication error is likely to occur, so if an error occurs during communication and the transmission is not completed. However, the receiving side can easily recognize where the transmission is from.

In addition to the above-described embodiment, for example, a plurality of trays for ejecting recording paper are provided and the received image is sent from the first page or the last page. It is determined by the NSF signal or the like sent in the pre-communication procedure, the trays to be ejected are automatically selected based on the determination result, and the recording sheets stacked in the normal order and the recording sheets stacked in the reverse order. It is also easy to configure so as to prevent mixing of and.

[0038]

As described above, according to the first and second aspects of the invention, the recording sheets are sorted and recorded and output in the correct order as long as the recording and outputting are performed in the same order as in the normal receiving operation. Therefore, it is not necessary to use a memory for sorting, and it is possible to avoid reception refusal due to memory over.

According to the third aspect of the invention, the recording sheets are sorted and recorded and output in the correct order as long as they are recorded and output in the same order as in the normal reception operation without using the memory on the reception side. Of course, since the image transmission order can be appropriately switched according to the recording type on the receiving side,
It is possible to prevent the transmission order from being unnecessarily switched to the receiving side (method of recording on roll paper) that does not need to change the transmission order of images.

According to the invention of claim 4, since the recording type of the receiving side is notified to the operator before transmission,
Based on this notification, the operator may change the order of the originals and insert the originals properly, so that the recording sheets are sorted and printed out in the correct order without using the memory during transmission and reception.

Further, according to the invention of claim 5, the recording sheets are sorted and recorded and output in the correct order as long as the recording and outputting are performed in the order of reception as in the normal receiving operation without using the memory on the receiving side. Of course, since the header attached to the first page of the fax transmission form is sent, even if the transmission was not completed due to an error during communication, it was sent from anywhere on the receiving side. You can easily recognize the things.

According to the sixth aspect of the present invention, the recording sheets are sorted and recorded and output in the correct order as long as the recording and outputting are performed in the same order as in the normal receiving operation without using the receiving side memory. Of course, due to operator switching, the header attached to the first page of the fax transmission will be sent first to the address where a communication error is likely to occur, so an error will occur during communication and the transmission will be completed. Even if you do not do so, the receiving side can easily recognize where the transmission is from.
