Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having a plurality of transmission systems.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus of this type has
Before direct transmission, which scans the original from the scanner in page synchronization with the communication procedure, storage transmission in which the original is temporarily stored in the image memory and then transmitted, or before the line is connected and the receiving function of the other terminal is known It was equipped with a transmission method such as reading a document from a scanner.

Further, this type of facsimile apparatus, when transmitting a document, has a remaining amount of image memory, a communication mode, and an I / O.
The operator recognizes various factors such as the use status of the document, the status of the transmission destination line, the document reading resolution, and the character / photo mode, and the transmission is performed according to the operator's instruction or the transmission method according to the type of the transmission service.

[0004]

However, the above-mentioned conventional example has the following drawbacks. (1) In direct transmission, since the original is read page by page in synchronization with the page synchronization signal or command / response in the communication procedure, the original must be placed on the scanner until the transmission is completed. No other user can use the facsimile machine during that time. (2) In conventional storage and transmission, since the original to be transmitted is temporarily stored in the memory, the usage time of the scanner of the facsimile apparatus is shorter than that in direct transmission, but the time from the completion of reading the original by the scanner to the completion of transmission Therefore, the operator often leaves the facsimile machine when the transmission is completed. Therefore, in this case, it is necessary to confirm whether or not the manuscript has been sent later, which requires outputting reports or displaying the sending result using the operation panel for searching. It requires very troublesome operation and labor for the operator. (3) In the conventional store-and-send operation, when the document to be sent is stored in the memory and the memory becomes full, the data of all pages stored until then is discarded and the store-and-send service is interrupted. Must be lowered or the photograph mode must be switched to the character mode to read again from the first page of the transmission original. Moreover, in this case, even if the transmission original is stored again, there is no guarantee that all pages of the transmission original will be stored in the memory, which may be a waste of time. (4) Also, in the conventional accumulation transmission, when the original to be transmitted is stored in the memory and the memory becomes full, the accumulated pages are discarded and the pages that have been accumulated until then and the subsequent pages are manually or automatically generated. Although the method of sending with was adopted,
It is necessary to store the pages interrupted by the memory full and the subsequent pages in order at the time when the transmission is completed or when the memory becomes empty, and the state of the facsimile machine must be constantly monitored. There is complexity. (5) When the line is in use, if you try to perform direct transmission, an error message such as "The line is in use" is displayed, and the direct transmission is rejected, and the status of the fax machine is monitored until the line becomes free. If there is a document waiting to be sent, it is difficult to interrupt the document waiting to be sent by an operation. (6) If the operator does not specify the transmission method, the default transmission method set in the facsimile machine is selected. In addition, the judgment for sure transmission is made so that an error such as memory full does not occur during the transmission operation from the communication mode, remaining memory capacity, resolution, character / photo mode, and status of accumulated transmission resources and line resources. It was entirely up to the operator. Therefore, if the operator has no knowledge of the above-mentioned setting items and the state of the facsimile apparatus, the transmission operation is repeated many times. On the other hand, on the other hand, the operator has to understand the characteristics of each transmission method, which is complicated. (7) When transmitting in the G3 facsimile procedure, especially when the line condition is bad on an international line, the partner G3 facsimile device returns an RTN (retraining negative signal). Some models have a resending function, and most of the models have a page resending function only for normal storage and transmission, except for models having a work memory capable of temporarily storing document data in page units. However, the operator cannot usually know such a situation. Therefore, an incomplete document in which a line dropout frequently occurs is transmitted to a partner facsimile machine having a bad line condition by direct transmission to which the page resending function is not applied. It had the drawback of sending (8) In a facsimile machine connected to ISDN, a model capable of simultaneously communicating two B channels,
It is necessary to provide a density converter for each channel, or to prepare a work memory of a large size and use one density converter on a page-by-page basis in a time-division manner. It has been a factor of increasing the cost of the device.

An object of the present invention is to provide a facsimile apparatus which can perform image transmission by an efficient transmission method without imposing a burden on the operator.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a direct transmission function of sequentially transmitting image data read by an image reading device after calling a destination, and after temporarily storing the read image data in a memory, It has a normal store and send function that calls the other party to send image data and stops the store and send service when the image data is being stored due to memory full.
In a facsimile device in which the image reading device can stop reading in units of a predetermined number of lines, the reading operation is interrupted when the image memory becomes full while the read image data is being accumulated, and the transmission original document being read is set. A second storage and transmission function that automatically calls or starts transmission to the other party by the operator's instruction as it is, and starts reading by the image reading device when the other party's receiving capability is determined by negotiation with the other party. The image data is stored in the memory and the transmission operation is performed. The storage operation and the transmission operation are performed asynchronously until the image memory becomes full, and the reading operation is interrupted when the image memory becomes full. It has a preceding direct transmission function.

By providing the above-mentioned accumulation preceding direct transmission function, the time from the start of reading to the end of transmission in the image reading apparatus is shortened as compared with normal accumulation transmission or direct transmission, and the transmission original is separated from the image reading apparatus. Therefore, the occupation time of the image reading apparatus can be shortened and the utilization efficiency of the facsimile apparatus can be improved.

[0008] Further, this accumulation-preceding direct transmission function does not lengthen the time from the end of reading image data to the end of transmission as in the above-mentioned normal accumulation transmission, and the transmission state can be easily monitored. Since it is not necessary to check, it is possible to eliminate troublesome operations and troubles.

In addition, the time from the start of reading the original to the end of the storage preceding direct transmission function is almost the same as that of the normal storage transmission described above, and the ISDN B channel is set to two.
With models that can simultaneously communicate with channels, transmission can be performed during direct reception or during normal storage and transmission. Further, in this accumulation preceding direct transmission function, the image reading system and the communication system operate without page synchronization, and operate to stop the reading operation when the memory is full.
The image reading operation is appropriately controlled according to the fluctuation of the remaining memory amount based on the processing speed of the image density converter. Therefore, even when performing the above-mentioned two-channel simultaneous communication, one image density converter can be used for processing without using a large-sized work memory, and the simultaneous transmission function can be realized at low cost.

Further, by providing the second accumulation / transmission function, interruption due to memory full can be avoided, labor for reaccumulation of an untransmitted document can be eliminated, and further, from the end of reading image data to the end of transmission. Since the time does not become long unlike the above-mentioned normal accumulation and transmission, and the transmission state can be easily monitored, there is no need to check the transmission result later, and troublesome operation and trouble can be eliminated.

Further, when the line is in use at the time of direct transmission, at the time of direct storage prior to storage, or when the memory is full in the second storage and transmission, by making a line reservation, it is possible to provide a convenient device.

When the operator does not specify the transmission method, the transmission method is automatically determined from the communication mode, the remaining memory, the resolution, the character / photo mode, the setting status of the line resource and the storage / transmission resource or the usage status. By doing so, an appropriate transmission method can be easily obtained without requiring detailed understanding by the operator.

The line status of each G3 destination is judged by the return rate of the RTN, the history is stored in the one-touch dial or the speed dial, and the transmission method is automatically determined according to the contents, so that the line status can be confirmed. Appropriate transmission can be performed by selecting the accumulated transmission in which the page resending function is applied to a bad partner.

Further, since the above-mentioned accumulated preceding direct transmission causes the image reading system and the communication system to operate without page synchronization and to stop the reading operation when the memory is full, two B channels of ISDN are simultaneously operated. Even if two-channel simultaneous communication is performed in a communicable model, one image density converter can be used for processing without using a large-sized work memory, and the simultaneous transmission function can be realized at low cost.

FIG. 3 is a schematic diagram for explaining a management record for one destination of one-touch dial or speed dial.

This management record is stored in the RAM 33 and contains the dial type, dial serial number, communication mode, RTN occurrence rate and dial serial number. Of these, the RTN generation rate is a value obtained by dividing the total number of RTN signal receptions returned from the partner G3 facsimile machine by the total number of transmitted pages when 100 is transmitted to the destination based on the record and multiplied by 100. And is used to determine whether or not the transmission method is accumulated transmission when transmitting in G3. And if this RTN occurrence rate exceeds the threshold,
Give priority to store and send.

The facsimile apparatus of this embodiment has the following four transmission methods. (1) Direct transmission method in which the image data read by the scanner unit 314 is sequentially transmitted after calling the other party (2) The read image data is temporarily stored in the image memory 34, and then the other party is called and the image is displayed. Ordinary storage and transmission method that transmits data and cancels the call when the memory is full while storing image data (3) When the image memory 34 becomes full while storing read image data, the reading operation is interrupted. , The second storage and transmission method in which a transmission original being read is set and a call is automatically sent to the other party to start transmission by the operator's instruction (4) At the time when the other party's receiving capability is determined by negotiation with the other party The scanner unit 314 starts reading, stores the image data in the image memory 34, performs a transmission operation, and stores the image data until the image memory 34 becomes full. It performs a transmission operation asynchronously with the image memory 34
The storage-preceding direct transmission method in which the reading operation is interrupted when is full is to be noted that the second storage-transmission method and the storage-preceding direct transmission method are novel transmission methods that have not existed before. Further, in the second accumulation transmission method and the accumulation preceding direct transmission method, when the reading operation is interrupted due to the image memory being full, the reading operation is performed when the image memory 34 has a vacant space of a predetermined capacity due to the transmission of the image data. It will restart.

4 to 6 are flow charts showing the above-mentioned accumulated preceding direct transmission.

When the transmission method is determined to be the accumulation-preceding direct transmission by the transmission method determination process described later with the original set on the scanner 314, the redial counter is initially set (S21) and the redial out is checked (S22). If the call is not redialed out in (), a call is made (S23), and if the other terminal can be connected (S2).
4) A message indicating that the document is being transmitted is displayed (S25), the call state existing on the RAM 33 is set to "waiting for transmission data" (S244), and a message indicating that the document is being read after negotiation of the terminal capability with the partner terminal is displayed. (S23
1) The document reading from the scanner unit 314 is started (S
232), the scanner state existing in the RAM 33 is set to "scanner reading" (S233), and the event waiting state is set.

Thereafter, there is a block end event from the I / O control unit (A) 38 (S235), and a transmission data ready event is transmitted to the transmission data transfer system (S23).
6) If it is detected that the document on the scanner 314 has not been read (S237), a free memory block on the memory 34 is acquired (S238), and if it is found that the memory is not full (S23).
9), and displays that the document is being read (S23
1) After that, the operation is continued until the reading of all pages of the original is completed.

When the reading is completed (S23
7), that effect is displayed (S241), the scanner resource is released (S242), and the process ends (S243).

On the other hand, since the communication state of the transmission data transfer system is set to "waiting for transmission data" in S214,
It is waiting in this state (S215), and the above S23.
Since the transmission data ready event is transmitted in 6, the waiting state is released (S216), the raw image data read from the scanner unit 314 is stored in the memory 34 in block units, and this data is encoded / decoded. 31
1 is converted into facsimile coded data by the memory 34
Stored in.

This code data is used for the ISDN I / F unit 3
Is sent to the ISDN line via S7 (S217), and the communication status is set to "Transmitting transmission data" (S21).
8) Waiting for the transmission data transfer end event.
When the transmission data transfer end event comes from the ISDN I / F unit 37 in this state (S220), the waiting state is released and the transmitted block in the memory 34 is released (S2).
22) Until the transfer of the final data block is determined to be completed (S223), the above control is repeated.

Thereafter, as a result of the determination of the presence / absence of the transmission data (S224), if the transmission data is present, the process shifts to the transmission data transfer (S217). If not, the communication state is set to "waiting for transmission data" ( S225), wait for the event.

When the transfer of the final data block is completed in S223, the line resource is released (S226), the completion of transmission is displayed (S227), and the process is completed (S228).

When it is not possible to connect to the partner terminal in S24, if the partner terminal is busy (S26), the redial counter 11 is decremented (S211),
A message indicating the standby for redial is displayed (S212), and a redial timer is activated (S213). When the time-out occurs (S214), the process returns to S22 and the redial operation is performed.

FIGS. 7 to 12 are flow charts showing the determining operation of each transmission method, and FIGS. 13 to 15 are schematic diagrams showing display screens for operation in the determining operation of the transmission method.

First, the operator operates the operation panel 4 to set the resolution button 41 to super fine, the character / photo button 42 to photograph, the communication mode to G4 facsimile, and the one-touch button [A] It will be explained from the point where it is pressed.

When the one-touch button [A] is pressed,
Scanner resources are acquired (S11). As a result, it is judged whether or not it has been acquired (S12), and if it can be acquired, the screen (5-1) is displayed to confirm the designation regarding the transmission service (S13). Also, if local copying is in progress, scanner resources cannot be acquired, and the scanner unit 3
A screen (5-2) indicating that 14 is in use is displayed (S122).

In order to specify the transmission service, for example, when the operator specifies time-specified transmission, it is necessary to first press the time specifying button 410 before pressing the one-touch button [A], and the result is stored in the RAM 33. It Therefore, in the determination of S13, the transmission service designated by the operator is determined using such data. If the mail post transmission (S14), polling transmission (S15), and time designation transmission (S16) are selected, the normal storage transmission is performed (S12).
4).

On the other hand, when nothing is specified for the transmission service, the communication mode button 43 is next pressed (S
161), the communication mode display changes from G4 in (5-1) to G3 as shown in (5-3) (S16).
2). When the transmission method button 49 is pressed here (S1
63), the screen (5-4) is displayed, the transmission method display is switched from automatic transmission to direct transmission (S164), and the selection button 45 is pressed (S165), the screen (5-) is displayed.
7), and the transmission method display is switched to the accumulation-preceding direct transmission (S166).

In the above display state, the set button 4
When 8 is pressed (S167), control of each transmission method is started in S17 and thereafter.

First, when the storage direct transmission is designated by the transmission system designation check (S19), the line resources (including the B channel resource and the G3 / G4 communication resource) are checked (S125). If you can get it, move to screen (5-8). If you can't get it,
The line is in use and a line reservation is made (S127, S12
8) Then, the fact that the stop key is valid is displayed in the line reservation state waiting for a free line (5-9). here,
When the stop button 46 is pressed or no document is detected (S130, S139), the scanner resource is released (S130).
132), the screen moves to the screen (5-10) and ends (S1).

When direct transmission is designated (S18), almost the same operation is performed (S1).
34-S141, 5-12-5-14).

Further, when the second accumulation / transmission is designated, the accumulation / transmission resources (the buffer on the memory 34, the pixel density converter 310, the encoder / decoder 311 and the like) are acquired (S149). If you can not get (S15
0), reservation of storage and transmission resources, and a screen indicating that (5-
5) is displayed (S154), and the process proceeds to the accumulated preceding direct transmission. If the accumulated transmission resource can be acquired, the line resource is acquired (S151), and if not (S152), the line resource is reserved and a screen (5-6) indicating that is displayed. (S155), the process proceeds to normal storage transmission (S124). When the line resource can be acquired, the screen (5-15) showing that the resource is being stored is displayed, and the second
The process proceeds to storage transmission (S153).

On the other hand, when the start button 47 is pressed on the screen (5-3) of S162 (S168) without specifying the service or the transmission as described above, the remaining memory amount is checked (S111), and the remaining memory is left. If there is no amount, direct transmission is performed, and if there is a small amount, storage direct transmission is performed.

If the remaining memory capacity is sufficient and the communication mode is the G4 mode (S115), the resolution is determined (S15).
143, S144) and determination of character / photo mode (S14
5, S146), when the resolution is set to super fine and the character / photo mode is set to photo, the transmission method is determined to be direct transmission, and the screen (5-11) is displayed. Further, when the resolution is set to super fine and the character / photo mode is set to character, the transmission method is determined to be the accumulation preceding direct transmission.

Further, the determination of the resolution (S143, S14
In 4), when it is not super fine, the transmission method is determined to be the accumulation preceding direct transmission for the photograph by the character / photograph mode determination (S147, S148), and if it is the character, the transmission method is set to the normal transmission method. It is decided to store and transmit.

In S115, the communication mode is set to G.
In the case of the 3 modes, the process shifts to the RTN occurrence rate check (S116), and the RTN occurrence rate of the destination management record of the one-touch dial [A] is referred to. If the threshold is not exceeded, the resolution is determined (S143, S14
4) and determination of character / photo mode (S145 to S148)

Is displayed (S157), and the normal storage transmission is started (S124). If the line resource can be acquired, a screen (5-15) showing that the data is being stored is displayed, and the normal storage / transmission is started (S124).

[0049]

According to the present invention, by introducing the accumulation-preceding direct transmission, the original is read prior to the transmission without being synchronized with the page synchronization signal in the communication procedure as in the direct transmission. Scanning of the document to be sent ends long before the transmission is completed.
Therefore, the operator can quickly leave the facsimile machine and can use the scanner for other services such as copying during this transmission, which has the effect of increasing the efficiency of use of the facsimile machine.

Further, by the above-mentioned accumulation-preceding direct transmission, it is possible to realize a function substantially equivalent to the original reading time of the accumulation transmission without using the density converter. Therefore, there is an effect of reducing the cost of hardware.

Further, the above-mentioned accumulated preceding direct transmission has an effect of shortening the time from the reading to the end of communication as compared with the accumulated transmission and the direct transmission.

Further, the accumulated preceding direct transmission shortens the time for the operator to monitor the transmission status,
This has the effect of eliminating the need to search the transmission result on the communication result report or the operation panel.

Further, by introducing the second accumulation / transmission for starting the transmission when the original becomes full while being stored in the memory, reliable transmission can be performed without depending on the capacity of the memory provided in the facsimile apparatus. effective. Further, it is effective in reducing the time and effort required for the operator to perform the operation again with the memory being full.

Further, when the line is in use during direct transmission or direct transmission before storage, provision of means for preferentially reserving the line eliminates the need for the operator to monitor the vacancy of the line, and the facsimile apparatus This has the effect of reducing the time for restraining the operator. Further, when there is a document waiting to be transmitted, there is an effect of improving the drawback that it is difficult to interrupt the document waiting to be transmitted by an operation.

When the operator does not specify the transmission method, the conventional method selects the default transmission method set in the facsimile machine.
When the memory transmission is set as the default, the memory capacity of the facsimile machine is not sufficient, and there are many cases where the memory becomes full during storage. However, in the present invention, a means for automatically determining the transmission method so as not to cause an error such as a memory full during the transmission operation from the communication mode, the remaining memory amount, the resolution, the character / photo mode, the situation of the stored transmission resource and the line resource. By providing
There is an effect that even an operator who does not have knowledge about the above-mentioned setting items and the state of the facsimile apparatus can perform reliable transmission without repeating the failure.

Further, there is provided means for registering the frequency of occurrence of the RTN signal returned from the other party's G3 facsimile in the other party's telephone number registration means when transmitting in the G3 facsimile procedure, especially when the line condition is bad on an international line or the like, By providing a means for automatically determining the storage / transmission method capable of preferentially retransmitting a page when transmitting to a partner terminal in a poor line condition by the G3 procedure, there is an effect that more reliable transmission of document contents can be performed.

Further, since the above-mentioned accumulated preceding direct transmission allows the image reading system and the communication system to operate without page synchronization and to stop the reading operation when the memory is full, two channels of the ISDN B channel are simultaneously operated. Even if two-channel simultaneous communication is performed in a communicable model, one image density converter can be used for processing without using a large-sized work memory, and the simultaneous transmission function can be realized at low cost.
