Abstract

PURPOSE:To surely sent interrupted picture information to a destination by sending picture information of a page during transmission when an interrupting operation is applied during picture information transmission and bringing the remaining pages into the recall state to the same destination. CONSTITUTION:When an interruption key of an operation display section 6 is turned on before the end of picture information transmission, remaining originals set on a scanner 4 and subject to coding compression by a coding/ decoding section 7 and stored in a picture storage device 8. Moreover, the same destination is recalled and the transmission information such as destination information is stored so as to send the stored picture information. Then the interruption information is sent to the destination and when the interruption confirmation signal representing the confirmation of the picture information interruption is received from an opposite equipment, the destination is recalled with an elapse of a prescribed recall waiting time and the interrupted picture information is sent again. Other picture information is able to be sent during the recall standby state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transmission system for a facsimile machine having an interrupt function.

[Prior Art] In Group 3 facsimile devices, when transmitting image information, if the image information consists of multiple originals, a series of image information to be transmitted is transmitted to the destination in one image information transmission operation. are doing.

For this reason, for example, when transmitting image information using a facsimile machine, if it becomes necessary to transmit other urgent image information, conventionally, the operator of the transmitting device displays the operation display of the own terminal. By turning on the stop key, the image information transmission in progress was forcibly interrupted.

[Problems to be Solved by the Invention] However, such conventional interruption methods have the following disadvantages.

In other words, when the stop key was turned on, the transmitting device immediately stopped transmitting image information at that point, so the image information being transmitted consisted of multiple sheets of original and image information transmission was interrupted in the middle. In this case, it is necessary for the operator to perform an operation to send the remaining pages of the manuscript to the same destination again, resulting in an inconvenience in that the operator takes much time and effort.

Further, when the S1 key is turned on in the middle of a page, there is also an inconvenience in that the image information being transmitted is not properly transmitted.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a transmission system for a facsimile machine that can solve the problems of the conventional apparatus and appropriately interrupt the transmission of image information.

[Means for Solving the Problem] The present invention includes an interrupt operation means for inputting a command to interrupt image information transmission, and when an operation input is input to the interrupt operation means during image information transmission, the interruption operation means stops during image information transmission at that time. When the page transmission is completed, the transmission of image information is interrupted, and the transmitting device enters a re-calling state for transmitting the image information of the remaining pages to the same destination.

[Effect] Therefore, the image information of the page that is being transmitted when the interrupt operation is commanded is completely transmitted, and the remaining pages are transmitted to the destination without being called again, so the interrupted image The cleavage information transmitted by information transmission is reliably transmitted to the destination.

Further, the operator's effort is also reduced.

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

FIG. 1 shows a facsimile machine according to an embodiment of the present invention.

In the figure, a CPU (Central Processing Unit) 1 controls each part of the facsimile machine and processes facsimile transmission control procedures.

This constitutes the work area.

The scanner 4 is for reading original images at a predetermined resolution, the plotter 5 is for recording and outputting images at a predetermined resolution, and the operation display section 6 is for operating this facsimile device. It consists of various operation keys and various indicators.

The encoding/decoding unit 7 encodes and compresses the image signal and decodes the encoded and compressed image information into the original image signal, and the image storage device 8 encodes and compresses the encoded and compressed image information. This is for storing a large amount of image information in a different state.

The modem 9 performs modulation and demodulation processing for transmitting digital data using the public telephone network, which is an analog line, and the network control device 10 connects this facsimile device to the public telephone network. It is. This network control device 10 also has an automatic call origination/reception function.

These CPUI, ROM2, RAM3, scanner 4
, plotter 5, operation display section 6, encoding/decoding section 7, image storage device 8, modem 9, and control device 10 are connected to a system bus 11, and data is exchanged between these elements. Exchange is performed via this system bus 11.

FIG. 2 shows an example of operation keys on the operation display section 6. As shown in FIG.

In the figure, a start key 68 is used to input a command to start the operation of the facsimile machine, a stop key 6b is used to manually command the stop of the operation of the facsimile machine, and a numeric keypad 6c is used to input a command to start the operation of the facsimile machine. The clear key 6d is used to erase input data from the numeric keypad 6c, and the interrupt key 6e is used to cancel the sending or receiving operation of the facsimile machine. This is for manually commanding the interruption of operations.

FIGS. 2(a) and 2(b) show an example of the processing performed by this facsimile machine at the time of transmission.

When sending, first call the destination and receive a non-standard equipment signal N5F (facsimile transmission procedure signal) from the destination (
Process 101), check whether the non-standard device signal NSF includes information indicating that there is an interruption function (determination 102).
. When the result of this judgment 102 is No, the process shifts to the standard facsimile transmission procedure.

When the result of judgment 102 is YES, a non-standard device setting signal NSS including the use of the interrupt function is sent to the partner device (process 103), and a training procedure is executed in the same way as the normal procedure (process 104). ), image information transmission is started (process 105).

Before this image information transmission ends (the result of judgment 106 is N
O) The interrupt key 6e of the operation display unit 6 is turned on and an interrupt command is inputted, or the interrupt signal SUS, which is a non-standard facsimile procedure signal that instructs to interrupt image information transmission, is received from the other party's device. I'm watching what happens (
No loop of decisions 107 and 108).

When the result of the decision 106 is YES, at that point the routine shifts to the normal facsimile transmission procedure.

If the result of judgment 107 is YES, the page that is being sent at that time is terminated (the result of judgment 109 is YES).
), the display device of the operation display section 6 displays, for example, "
A standby instruction guidance message "Please wait" is displayed (process 110).

If the result of judgment 109 is YES, it is checked whether the image information being transmitted at that time is to a memory device using the function of image storage device 8 (decision 111).

When the result of the judgment 111 is NO, the display of the standby fingernail guidance message is started (process 112), the remaining originals set in the scanner 4 are read, and the encoder/decoder 7 encodes and compresses them. Later, the image storage device 8
(process 113). At this time, transmission information such as destination information is also stored so that the same destination can be called again and the accumulated image information can be transmitted. Note that when the result of determination 111 is YES, processes 112 and 113 are not performed.

Next, a process 114 for sending an interruption signal SUS to the partner device
), in response, an interruption confirmation signal SUA (non-standard facsimile reception signal) is sent, which indicates that the other device has confirmed that the image information transmission has been interrupted. (Judgment 11)
．． 5,116 No loops).

When the result of the judgment 115 is YES, the display of the standby instruction guidance message is terminated (process 117), and the process waits until a predetermined re-call waiting time elapses (judgment 118).
No loop), the destination is re-called (119), and the interrupted image information transmission is resumed.

Note that during this re-call waiting period, other image information transmission can be performed.

Further, when the result of judgment 116 is YES, error termination processing 120 is executed to display a message such as a greeting that the other device did not accept the interruption of image information transmission, and this image information transmission is terminated. do.

Further, when the result of judgment 108 is YES, an interruption confirmation signal SUA is sent to the other party's device, image information transmission is ended at that point (process 121), and the process waits until a predetermined re-call waiting time elapses. (No loop of judgment 12), process 122) to re-call the destination, and resumes the interrupted image information transmission. Note that in this process 121 as well, similarly to the judgment 111 and processes 121 to 113, when memory transmission is not performed, the images of the remaining originals are stored in the image storage device 8.

In this way, when transmitting image information, if an interrupt command is input on the own terminal side, the screen information transmission is interrupted after a certain period of time has passed, after waiting for the end of the page being transmitted at that point. When this happens, the interrupted image information transmission will be resumed.

Further, when it is notified that an interruption command has been inputted on the partner device side, image information transmission is temporarily interrupted at that point, and when a certain period of time has elapsed, the interrupted image information transmission is resumed.

In addition, in any case, while the facsimile is on standby, it is possible to accept the start of another image information transmission. FIGS. 4(a) and 4(b) show an example of processing performed by this facsimile apparatus at the time of transmission.

When receiving a call, first, when an incoming call is detected, the called station identification signal CE is sent.
D, and processing 201, 202) for sequentially sending out the non-standard device signal NSF including the information that there is an interruption function, processing 2
02 is completed, the non-standard device setting signal NSS is received from the partner device within a specified time (Judgment 2
03,204 NO loop).

If the result of judgment 203 is YES, it is checked whether the non-standard device setting signal NSS includes the interrupt function (decision 205). When the result of this judgment 205 is NO, the routine proceeds to a normal facsimile transmission procedure.

When the result of the judgment 205 is YES, the training procedure is executed in the same way as the normal procedure (process 206), and image information reception is started (process 207).

While receiving this image information, it monitors whether the interrupt key 6e of the operation display unit 6 has been operated, whether the interrupt signal SUS has been received from the other party's device, and whether the reception has ended (determination 208). , 209, 210 NO loop).

When the result of the judgment 208 is YES, it is determined whether the procedure signals IEOM and NPS have been received to notify the end of the page.
Alternatively, it waits until it receives the procedure end signal EOP (NO loop of judgments 211 and 212).

When the result of judgment 211 is YES, the interruption signal S
The process 213) for sending the US is monitored to see if the interruption confirmation signal SUA is received from the partner device within a specified time after completing the process 213 (NO loop of judgments 2]4 and 2]5).

When the result of judgment 214 is YES, for example, “
Image information reception has now been interrupted. The remaining image information will be resent later. ” is recorded and output from the plotter 5 (216), and this reception processing is terminated.

When the result of the judgment 215 is YES, the process 217 is executed with the error end displaying a message such as a greeting that the other device did not accept the interruption of the image information transmission, and this image information receiving process is ended. do.

Further, when the result of the judgment 209 is YES, the interruption confirmation signal SUA is sent out (process 2I8), and the process moves to process 216.

Further, when the result of determination 210 is YES, and
When the result of the determination 212 is YES, a normal termination procedure process 219 is executed to terminate this image information receiving process.

In this way, when receiving image information, when an interrupt command is input on the own terminal side, the other device is notified that the image information transmission will be interrupted after waiting for the end of the page being received at that time. However, if the image information transmission ends when the page is finished, the image information transmission interruption procedure is not performed.

Further, when it is notified that an interruption command has been inputted on the partner device side, image information reception is interrupted at that point.

Furthermore, when receiving image information is interrupted, a message to that effect is recorded and output from the plotter 5.

FIG. 5(a) shows an example of a transmission procedure when an interrupt command operation is performed on the transmitting side with the above configuration.

In this case, time T1 while transmitting the image information PIX
, the interrupt key 6e on the operation display section 6 of the transmitting device is operated, and when the transmission of the image information P1x for that page is completed, an interrupt signal SUS is sent to the receiving device. Since the receiving (three devices responded with the interruption confirmation signal SUA), the transmitting device sends out the procedure signal DCN to restore the line.

Further, an example of the transmission procedure when an interrupt command operation is performed on the receiving side is shown in FIG. 2(b).

In this case, time T2 while receiving the image information PIX
, the interrupt key 6e on the operation display section 6 of the receiving device is operated, and when the transmission of the image information PIX for that page is completed and the procedure signal EOM is received, the interrupt signal SUS is sent to the transmitting device. There is. In response to this, the transmitter responds with an interruption confirmation signal SUA and sends out a procedure signal DCN to restore the line.

In this way, according to this embodiment, the image information transmission can be appropriately interrupted in the middle of the image information transmission, so that, for example,
It is possible to interrupt the image information transmission in progress by urgent image information transmission.

[Effects of the Invention] As described above, according to the present invention, the interrupt operation means is provided for inputting a command to interrupt the image information transmission, and when the interrupt operation means is inputted during the image information transmission, the interrupt operation means is operated. The image information transmission is interrupted when the transmission of the page currently being transmitted is completed, and the transmitting device enters a re-calling state in order to transmit the image information of the remaining page to the same destination. The image information for the page that is being transmitted when is commanded is completely transmitted, and the remaining pages are called again and transmitted to the destination, so they should be transmitted when the image information transmission was interrupted. The image information is reliably transmitted to the destination. Moreover, the effect of reducing the operator's effort is obtained.
