Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to facsimile devices, and in particular, when a receiving device is equipped with a plurality of facsimile devices, when an incoming facsimile device cannot receive an incoming call for some reason, another facsimile device can receive a call. The present invention relates to a facsimile device which allows a facsimile device to perform proxy reception.

(Prior Art) When dialing to send a document by facsimile, if the other party's facsimile device is in use, out of paper, paper jammed, etc., the document cannot be sent.

In such a case, conventionally, the operator on the sending side telephoned the location where the other party's device was installed, informed them that it was not possible to send, and asked them to restore it to a state where it could receive.

However, if two or more facsimile machines are installed on the receiving side, the operator on the sending side can quickly send the message without waiting by sending the message to another facsimile machine. Initially, when the operator on the sending side telephoned the receiving side to inform them that they could not send as described above, they would ask if they had a spare facsimile machine, and if so, they would ask for the phone number and send the message to this spare facsimile machine. I was trying to do that.

This conventional method is time-consuming for the operator,
For example, JP-A-59-174071, JP-A-63-
An invention as disclosed in Japanese Patent No. 10874 has been made.

The invention disclosed in the former publication stores a first destination and a second destination (
A sub-destination) is registered, and if the first destination cannot be sent, the second destination is automatically called and sent.

In addition, the invention disclosed in the latter publication stores multiple telephone numbers divided into multiple groups in the memory of the sending facsimile device, and when the destination facsimile device cannot receive the same number, This allows the fax to be sent to other phone numbers within the group.

(Problem to be Solved by the Invention) The invention disclosed in the former publication is that if it is known that two or more facsimile machines are installed at the destination, a second facsimile machine can be sent to the first destination. Although it is possible to add and register a destination, there is a problem in that unless it is known that two or more facsimile machines are located at the destination, the second destination cannot be registered.

Furthermore, since the telephone numbers of two destinations are registered for one destination, there is a problem in that it is necessary to increase the memory capacity of one-touch dialing or speed dialing. Alternatively, if you maintain the current memory capacity for one-touch dialing or speed dialing,
There has been a problem in that the number of one-touch dials or speed dials that can be registered is reduced.

The invention disclosed in the latter publication has the same problem as above because the telephone numbers of destinations are registered in groups.

The purpose of the present invention is to eliminate the problems of the conventional device described above,
To provide a receiving device designation method that allows proxy transmission even if it is not known whether two or more facsimile devices are installed at a destination.

It is another object of the present invention to provide a receiving device designation method that allows registration of a normal number of one-touch dials or speed dials, and enables proxy transmission even if the memory capacity of the facsimile device is maintained at the current level.

(Means and Effects for Solving the Problems) In order to achieve the above object, the present invention provides a first storage unit that stores an alternate facsimile dial number, and a reception function that determines whether or not reception is possible when an incoming call is received. a receiving unit comprising a determining unit, a proxy facsimile dial number read from the first storage unit, and an initial identification signal adding unit that adds information on whether reception is possible from the receivable determining unit to the initial identification signal; an initial identification signal analysis section that analyzes the initial identification signal; a second storage section that stores the proxy facsimile dial number when the initial identification signal analysis section determines that reception is not possible; and a second storage section that stores the proxy facsimile dial number when reception is determined to be possible. It is characterized in that it includes an image information transmitting section that transmits information.

According to the present invention, when the reception unit receives an incoming call, the reception possibility determination unit determines whether the reception is possible or not, and outputs a signal indicating whether reception is possible or not, and the proxy facsimile dial read from the first storage unit. The number is added to the initial identification signal and output.

On the other hand, the transmitter analyzes the initial identification signal by the initial identification signal analyzer, and when it is determined that the initial identification signal cannot be received, the transmitter
The proxy facsimile dial number is stored in the storage unit.

Thereafter, processes such as automatic dialing, printing out, or display of this proxy facsimile dial number are performed using the proxy facsimile dial number stored in the second storage unit.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram of a facsimile machine showing an outline of the present invention.

The facsimile device 1 on the transmitter side has a control unit 1, a modem 12, and a network control unit (NCU) 13. The facsimile machine 1 further includes a proxy FAX function according to the present invention.
(Facsimile) A dial number storage memory 14 is provided.

On the other hand, the facsimile device 2 on the receiver side includes a control section 21,
It has a modem 22 and a network control unit (NCU) 23. The facsimile device 2 further includes a proxy FAX dial number input section 24, a proxy FAX dial number storage memory 25, and a receivability determination section 26 according to the present invention.

Note that the facsimile machines 1 and 2 each have a configuration that a normal facsimile machine has, but illustration thereof is omitted to make the explanation easier to understand.

Next, the operation of this embodiment will be explained with reference to FIG.

First, the operator on the receiver side registers the telephone number of the facsimile machine for proxy reception into the proxy FAX dial number storage memory 25 from the proxy FAX dial number input section 24 .

Therefore, when the facsimile machine 2 receives a call from the transmitter side, the facsimile machine 2 refers to the receivability determination section 26 and determines whether or not it is in a state where it can receive the call. Then, the result is placed on the NSF command and transmitted to the facsimile machine rI11 on the transmitter side.

An example of this NSF command (initial identification signal) is shown in FIG.

NSF command: flag field F1 address field A1 control field C1 non-standard function NSF, facsimile information field P IF.

and a frame check sequence FC5.

Facsimile information field PIF is a non-standard function NSF
A bit bl for instructing transmission to another facsimile, a bit b2 for indicating whether or not reception is possible, and the dial number of the facsimile machine for proxy reception are registered as part of this field. Note that even if reception is possible, the dial number may be registered, but if it is not registered, the data amount of the NSF command can be reduced and communication charges can be saved.

When the sending facsimile device rIt1 receives this NSF command, it analyzes the contents of the command, and if it is receivable, starts sending the image information. On the other hand, if reception is not possible, it is determined whether or not there is an instruction to send to another facsimile machine using the bit b1, and if there is an instruction, the NSF
The dial number registered in the command is sent to the proxy FA.
It is stored in the X-dial number storage memory 14. Then, the line to the destination facsimile machine 2 is disconnected.

Thereafter, the dial number is read out from the proxy FAX dial number storage memory 14 and dialed automatically. and,
If this facsimile device can receive image information, it transmits the image information.

FIG. 1 shows a functional block diagram of the main parts of the facsimile machine of this embodiment.

In the figure, 31 is an operation section of the facsimile machine, 32 is an abbreviated number storage section, 33 is a calling section, 34 is an NSF command (or initial identification signal) analysis section, and 35 is an image information transmission section. Further, 41 is an NSF command adding section, which has a function of adding bits b1, b2 and a dial number shown in FIG. 3 above. Note that other symbols in FIG. 1 indicate the same or equivalent components as in FIG. 2.

Next, the operation of this embodiment will be explained in detail with reference to FIG.

When the dial of the other party's machine is input from the operation section 31 when transmitting a document, a dial signal is output from the calling section 33, passes through the network control section 13, and is inputted to the network control section 23 of the destination facsimile machine.

When the destination facsimile machine receives a call, the receivability determination unit 26 determines whether or not it is receivable. N
The SF command (or initial identification signal) adding unit 41 is the proxy F
If the proxy FAX dial number is registered in the AX dial number storage memory 25, a bit instructing transmission to another FAX is set in bit b1 of the NSF command, and the dial number is added. Further, a bit indicating whether reception is possible or not is set in the bit b2 according to a signal from the receivability determining section 26. Note that when reception is possible, the proxy FAX dial number may not be added. The NSF command is sent via the network control section 23 to the network control section 13 of the sending facsimile machine.

20 The NSF command is sent to the NS of the sending facsimile machine.
It is sent to the F command analysis unit 34, and first it is determined whether or not it can be received. If the image information can be received, the image information transmitter 35 transmits the image information.

On the other hand, if reception is not possible, the proxy FAX dial number added to the NSF command is stored in the proxy FAX dial number storage memory 14.

Thereafter, a command to disconnect the line is issued to the network control unit 13, and the line is released.

When the line is released, the sending facsimile machine reads out the dial number stored in the proxy FAX dial number storage memory 14 and dials automatically. As a result, a line to the proxy facsimile machine is connected, and the image information is automatically transmitted to the proxy facsimile machine.

As described above, according to this embodiment, the dial number of the proxy facsimile machine is stored in the facsimile machine on the receiving side, and this is communicated to the facsimile machine of the sender. There is no need to store sub-dial numbers for each destination, as in the above, and the problem of a reduction in the number of one-touch dials or speed dials that can be registered is eliminated. Furthermore, it is clear that proxy transmission can be performed even if the source does not know whether two or more facsimile machines are installed at the destination.

FIG. 4 is a flowchart showing the operation of the embodiment. Since the content of this flowchart is the same as the operation content already described, a description of this flowchart will be omitted.

In the above embodiment, the sender's facsimile machine is dialed, but when the destination facsimile machine is in a state where reception is not possible, automatic dialing can be used to temporarily disconnect the line and automatically dial the facsimile machine on behalf of the sender. Alternatively, the designated proxy facsimile dial number may be printed out or displayed on a display (not shown). The operator can then call back the printout or displayed number to accomplish the desired facsimile transmission.

Next, a second embodiment of the present invention will be described with reference to FIG.

In this second embodiment, after the receiving facsimile machine has started receiving, it is possible to perform proxy reception when the receiving facsimile machine is unable to receive due to paper out, paper jam, etc. Compared to FIG. Since the functions are the same and the only difference is the function on the receiver side, only the flowchart on the receiver side is shown in FIG.

In FIG. 5, when the destination facsimile machine receives a call (step S1), it is determined whether or not it can receive the call (step S2). If the answer is yes, the process advances to step S4 and image information is received using the normal communication procedure. will be started.

When the reception of the image information for one page is completed, it is determined whether an MPS (multi-page signal) has been sent (step S5) and EO.
Has M (message completed) been sent? (Step S)
6) is determined.

In the case of MPS, the process proceeds to step S7, where it is determined whether or not it can continue to receive the message.If affirmative, the process proceeds to step S7.
4 and reception continues. However, if it is determined in step S7 that reception is not possible, the process advances to step S8 and the PI
Forcibly sends the F (procedure interruption affirmation) or PIN (procedure interruption denial) signal.

Note that this PIP or PIN signal is a signal that is output when an operation such as a conversation reservation is performed while receiving multiple pages of image information, and according to Recommendation T.30, the protocol procedure after outputting the PIP or PIN signal is NS after 15 seconds as one of the
It is determined that F is to be transmitted.

Therefore, in this embodiment, after 15 seconds have elapsed after forcibly outputting the PIP or PIN signal as described above, step S1
Execute 2. In other words, as shown in Figure 3, other FAX
The NSF command is output to the source facsimile machine by setting a bit bl instructing transmission to the sender and a bit b2 indicating that it cannot be received, and further adding an alternate dial number. The sending facsimile machine that received this is the first one.
As in the embodiment, the proxy dial number is stored in the proxy FAX dial number storage memory 14, and after line disconnection processing is performed, automatic dialing is performed to the proxy facsimile machine,
Print out or display this dialed number.

When step S6 is affirmative, that is, when EOM (end of message) is detected, the process advances to step SIO to determine whether or not it is possible to continue receiving, and if affirmative, the process returns to step S4 to continue receiving.

Note that the EOM (end of message) is received while a plurality of pages are being received when the sending side changes the mode or the like. For example, when trying to send a 5-page original, if the mode is changed from "normal" to "fine" after sending the 2nd page, the sending facsimile machine outputs an EOM signal instead of an MPS signal. And recommendation T.

According to No. 30, the destination facsimile machine receives N after 6 seconds.
It is defined that SF can be output and the next page's document information can be received in the changed mode.

Therefore, according to this embodiment, it is determined whether or not reception is possible when receiving EOM, and when it is determined that reception is not possible, 6
After seconds have elapsed, the process of step S12 is performed.

As described above, the second embodiment can realize proxy transmission in accordance with Recommendation T.30.

In the second embodiment, an alternate facsimile dial number is added to the NSF, but the present invention is not limited to this, and a new command can be issued using a code that is not recommended by CCITT T.30. You can make it, M
It may be added to the CF command.

(Effects of the Invention) As is clear from the above description, according to the present invention, since the proxy facsimile dial number is stored on the receiver side, the facsimile machine has a large number of proxy facsimile dial numbers, unlike the conventional device. There is no need to memorize the information, and the storage capacity can be used effectively.

Another advantage is that even if it is not known whether two or more facsimile machines are installed at the destination, transmission can be performed on behalf of the destination.

Furthermore, according to the invention of claim (2), there is an effect that even if reception becomes impossible after the start of reception, proxy transmission can be performed.
