Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of issuing an incoming call failure notification to a sender when an incoming call arrives and issuing an incoming call availability notification after restoration to the sender who issued the incoming call failure notification.

[0002]

2. Description of the Related Art Generally, a paper jam or a paper-free state of recording paper occurs on the receiving side in facsimile communication.
When the state of no remaining memory is generated, the transmitted image information cannot be received. In such a case, the incoming call is rejected.

However, in the above-mentioned conventional technique, it is not possible to know the other party who has requested the incoming call when the own facsimile apparatus is in the call-incapable state, so that appropriate measures cannot be taken thereafter.

Therefore, the facsimile apparatus disclosed in Japanese Patent Laid-Open No. 2-145041 has a means for acquiring and storing the requested party terminal number when the incoming call is requested when the incoming call cannot be received. I was able to know.

In the facsimile machine disclosed in Japanese Patent Laid-Open No. 4-10752, an ISDN line is used, and when an incoming call request is made from another facsimile machine during communication between the two facsimile machines, the facsimile machine will be used. The terminal number is acquired and stored, and after the communication is completed, polling reception is performed from the above-mentioned facsimile apparatus that has received the incoming call request.

[0006]

However, in the conventional technique presented in the above-mentioned Japanese Patent Laid-Open No. 2-145041, the acquisition,
Even if the stored destination terminal number can be displayed and known, it is troublesome because the subsequent notification of the call-disabling or recovery (call-ready) to the destination must be done by hand.

In the prior art disclosed in Japanese Patent Laid-Open No. 4-10752, the other party must have a polling transmission means and must use an ISDN line.

[0008]

It is an object of the present invention to solve the problems of the prior art as described above, and to notify the sender of an incoming call when the incoming call cannot be received without any manual operation and without necessarily using the ISDN line. A fax machine that can send a call notification, can send a call ready notification after recovery to the sender that sent the call failure notification, and can poll the facsimile document sent by the sender according to the call ready notification. It is intended to be provided.

[0009]

According to the first aspect of the present invention,
In a facsimile device capable of facsimile transmission / reception, when an incoming call arrives when the incoming call is not possible, the incoming call failure notification section for notifying the sender of the incoming call failure and the incoming call failure notification section of the sender sending the incoming call failure notification A source terminal number storage unit that acquires and stores the terminal number, and after restoration,
The transmission source terminal number storage unit is configured to include an incoming call availability notification unit that notifies the sender of the terminal number stored that the incoming call is available.

According to a second aspect of the present invention, in the facsimile apparatus according to the first aspect, the incoming call failure notification unit and the incoming call availability notification unit notify the sender of the incoming call failure notification and the incoming call availability notification, respectively, by a facsimile document. The feature is that it is configured to.

According to a third aspect of the present invention, in the second or third aspect of the present invention, a polling receiving unit is provided for polling and receiving the facsimile document transmitted by the transmission source in response to the incoming call notification by the incoming call notification unit. It is characterized by that.

[0012]

With the above configuration, firstly, the call originator is called when the call cannot be received, and the call originator is notified that the call cannot be received.
When recovering from the call-disabled state, a call-ready notification is issued.

Secondly, the G3 facsimile apparatus having the standard function can receive the above-mentioned incoming call failure notification and incoming call notification.

Thirdly, immediately after the recovery from the call-disabled state, it is possible to receive the information that the sender tried to send when the call could not be received, without the need for manpower.

[0015]

Embodiments of the present invention will be described in detail below in the case of a G3 facsimile machine. FIG. 14 is a block diagram showing an example of a facsimile apparatus in which the present invention is implemented. In FIG. 14, 1 is a control unit for managing and controlling the entire apparatus according to a built-in program, and 2 is an operator's instruction to the facsimile apparatus. An operation display section 3 including a keyboard for giving a message and a display means for giving a message etc. to an operator by a facsimile device, 3 is image information read by a scanner 4, and is compressed by an encoding / decoding section (DCR) 8. Image information data, received compressed image information data, D
A RAM for temporarily storing the image information expanded by the CR8, a plotter 5 for outputting the received image information expanded by the DCR8 via the RAM 3, and a remote facsimile machine 6 for the public telephone network. A network control unit (NCU) for setting a call between them, 7 is a communication control unit for performing facsimile transmission / reception according to the G3 protocol, 9 is a modem including a low speed modem and a high speed modem, and 10 is an image memory.

When transmitting a facsimile with such a facsimile device, first, the image information is read into the RAM 3 by the scanner 4 under the control of the control unit 1. The image information is compressed by the DCR 8 and stored again in the RAM 3. Further, the control unit 1 obtains the call-time designation information such as the destination designated by the operation display unit 2, and the NCU 6 to which the destination information is passed sets up a call with the designated destination. Subsequently, the communication control unit 7 executes the phase B via the low-speed modem, and then moves to the phase C and the RAM.
The compressed image information data in 3 is modulated by the high speed modem in the modem 9 and transmitted through the NCU 6.

Upon reception, after the call is set up by the NCU 6, the phase B is entered, predetermined communication is performed via the low-speed modem, the phase C is entered, and the compressed image information data is received. The image information data is stored in the RAM 3 via the NCU 6 and the communication control unit 7, further expanded by the DCR 8, and output to the plotter 5 via the RAM 3.

FIG. 1 is a block diagram showing the construction of the essential parts of the facsimile apparatus according to the first embodiment of the present invention. In FIG. 1, reference numeral 11 denotes an incoming call failure notification unit for notifying the sender that an incoming call is impossible when there is an incoming call when the incoming call cannot be received, and reference numeral 12 denotes a sender terminal number storage unit for acquiring and storing the terminal number of the sender. , 13 are incoming call enable notification units that notify the above sender of the incoming call availability. In the above description, the incoming call failure notification unit 11 and the incoming call possible notification unit 13 are the control unit 1 and the R unit as shown in FIG.
The transmission source terminal number storage unit 12 is composed of the RAM 3 and the communication control unit 7.

FIG. 2 is an operation flow chart showing the operation of the first embodiment. The operation of the first embodiment will be described below with reference to FIGS. 1, 2 and 3.

First, the NCU 6 detects an incoming call (incoming call) (S1). This is realized by detecting the CNG signal in the protocol sequence shown in FIG. The NCU 6 responds to this signal with a CED signal. Also, CED
Following the signal, an NSF signal, a CSI signal, and a DIS signal are transmitted. The NSF signal and the CSI signal do not have to be transmitted.

On the other hand, when the NCU 6 receives the CNG signal, the NCU 6 notifies the communication control unit 7 to that effect, whereby the communication control unit 7 is notified.
The incoming call failure notification unit 11 therein determines whether or not the own facsimile device is in a callable state (S2). That is, the control unit 1 belonging to the call-disabling notification unit 11 determines the state of the plotter 5 and the image memory.
While monitoring the state of the free space of 10, when it is detected that the plotter 5 is jammed or out of paper, or when the free space of the image memory 10 is below a predetermined capacity,
The state information is set in a predetermined area belonging to the incoming call failure notification unit 11 in the RAM 3. Then, the incoming call disabling notification unit 11 in the communication control unit 7 reads out the state information in the predetermined area and determines whether or not the incoming call is possible.

As a result, if the judgment of the call reception failure notification section 11 is "call reception is possible", D from the calling side to the called side shown in FIG.
After the transmission of the CS signal, the called side executes a normal procedure to receive the image information (S3), and the process ends.

On the other hand, when the judgment of the incoming call failure notification section 11 is "call termination is impossible", the terminal number storage section 12 acquires the source (calling side) terminal number from the TSI signal sent by the calling side. After receiving the DCS signal from the calling side, the incoming call failure notification unit 11 notifies the incoming call failure by the DCN signal (S
4). When the terminal number storage unit 12 acquires the transmission source terminal number, it stores the transmission source terminal number in a predetermined area belonging to the terminal number storage unit 12 in the RAM 3 (S5).

In the above, the NSF signal shown in FIG. 3 can be used as the call termination notification (S4) to notify the sender of the cause of the call termination. In this case, according to a predetermined promise, the sender issues a TSI signal to notify the receiving side (called side) of the source terminal number even though it has received the notification that the incoming call is impossible. The receiving side issues it in the procedure as shown in FIG.

In the above, the transmission source terminal number stored in the terminal number storage unit 12 is not limited to one. Whenever there is an incoming call when the incoming call is disabled, the sender is notified of the incoming call failure as described above, and a plurality of transmissions are sequentially sent to the subsequent addresses in the predetermined area belonging to the terminal number storage unit 12 in the RAM 3. The original terminal number is stored. Note that FIG. 11 is an operation flow of the transmission source that receives the notification that the call cannot be received. As is apparent from FIG. 11, when the sender receives the incoming call failure notification, it displays the incoming call failure on the display unit or stores the incoming call failure in the stored document data according to the presence or absence of the memory transmission.

FIG. 4 is an operation flow at the time of recovery from the incoming call impossible state of the first embodiment. As shown in the figure, when recovering from the incoming call disabled state (S11), the incoming call enable notification unit 13 determines whether or not there is an incoming call during the incoming call disabled state.
It is checked whether or not the source terminal number is stored in the predetermined area in the RAM 3 belonging to the terminal number storage unit 12 (S12). If it is not stored, the process ends without doing anything.

On the other hand, when the source terminal number is stored, the receivable state notifying unit 13 reads it out (S13) and starts the call to the other party of the terminal number (S14). Then, the own terminal number is transmitted by the TSI signal,
The NSS signal is used to notify the incoming call (S15), and the DCN signal is sent to disconnect (S16).

Subsequently, if there is still a stored source terminal number, the above operation is repeated with each terminal number as a call destination (S17), and transmission of all the stored source terminal numbers is performed. When the notification of receivability to the origin is completed, the process ends. Note that FIG. 12 is an operation flow of the transmission source that receives the incoming call notification. As is apparent from FIG. 12, when the sender receives the incoming call enable notification, the sender displays the incoming call enable on the display unit or sends the stored document data according to the presence / absence of storage in the memory.

As described above, according to the first embodiment, for all the senders who have received a call when the call cannot be received,
In addition to notifying that the call cannot be received, when the call returns from the call-disabled state, a call-ready notification is sent to the above sender, so that the sender can take appropriate action immediately when the call cannot be received or when the call recovers from that state. . The above embodiment is G3.
Although it shows the case of a facsimile machine, ISD
A facsimile machine using the N-line network can more easily realize the same function and can notify the reason why the call cannot be received.

FIG. 6 is a block diagram of the essential parts of a facsimile apparatus showing another embodiment of the present invention. In FIG.
Reference numeral 14 is a character generator, and the incoming call failure notification unit 11
7a uses the character generator 14 to expand the incoming call failure notification into a predetermined area in the RAM 3 as shown in FIG. 7A. ) Expands the notification of incoming call availability such as That is, in the first embodiment, the call failure notification and the call arrival notification are transmitted by the G3 phase B protocol (or the G4 protocol), whereas in the second embodiment, the G3 phase C, that is, the image. Sends an incoming call failure notification or incoming call notification as information. FIG. 8 shows an operation flow of the second embodiment at the time of notification of an incoming call failure. However, this flow chart shows the case where the calling side (the side trying to send the facsimile image information) issues an incoming call failure notification by the NSF signal when the NSF signal can be received. However, it is also possible to always issue the incoming call failure notification based on the image information in Phase C without determining whether the calling side can receive the NSF signal.

In FIG. 8, S21 to S23 are S1 to S1 in FIG.
Same as S3. Then, after S23, if the incoming call is not possible, it is determined whether or not it is possible to issue the incoming call failure notification by the NSF signal (S24). In other words, the source facsimile machine may not be able to receive the NSF signal, so that the second embodiment is clear to such a source (DC
That is, not only N is sent out) but a call-disapproval notification is to be sent out.

Therefore, S29 and S30 in the case where the call failure notification is possible are the same as S4 and S5 shown in FIG. 2. When the call failure notification by the NSF signal is not possible, the sender terminal number is set as described above. Is stored (S25), and the call is disconnected (S26). Then, the facsimile machine side which issues the notification that the incoming call is impossible is called to the sender (S
27), the image information in the RAM 3 as shown in FIG. 7A is transmitted (S28), and the process ends. Information such as that shown in FIG. 7A may be held in the RAM 3 as code information and may be expanded into a bitmap at the time of transmission.

Is the same as After reading the terminal number, the sender is N
It is determined whether or not an incoming call notification by the SS signal can be received (S34). Subsequent operations when received S38-S
41 is the same as S14 to S17 in FIG.

When the sender cannot receive the incoming call notification by the NSS signal (S35), the incoming call as shown in FIG. 7 (b) is made in the same manner as the incoming call failure notification shown in FIG. The availability notification is transmitted to the sender (S36) and the call is disconnected (S37). Hereinafter, S41 is the same as S17 in FIG.

FIG. 10 is a block diagram showing the essential parts of a facsimile apparatus according to the third embodiment of the present invention. In FIG.
Reference numeral 15 denotes a polling reception unit that polls and receives the facsimile document transmitted by the transmission source in response to the call arrival notification by the call arrival notification unit 13b.

In the third embodiment having the above-mentioned configuration, when the call arrival notification section 13b attempts to send the call arrival notification to the sender as described above after recovering from the call reception disabled state, the call arrival notification is sent. The unit 13b passes the transmission source terminal number to the polling reception unit 15 and requests transmission and polling reception of the incoming call enable notification. The polling receiver 15 makes a call to the other party (sender), sends an incoming call enable notification, waits in the call setting state, receives a facsimile document from the sender, receives it, and then the controller 1 Pass to.

FIG. 13 is an operational flow of the sender which receives the incoming call enable notification. As shown in FIG. 13, the facsimile document corresponding to the image memory is stored and the call which has been set as polling transmission is set. To send the above fax document.

As described above, according to the third embodiment, the facsimile document which cannot be transmitted due to the impossibility of the incoming call,
After restoration, it can be sent immediately without any human intervention.

[0039]

As described above, according to the present invention,
First, the call originator is called when the call cannot be received, and the call originator is notified that the call is not accepted when the call originator is notified. Therefore, the sender can take appropriate measures without losing the opportunity.

Secondly, since the G3 facsimile apparatus having the standard function can receive the above-mentioned incoming call failure notification and incoming call notification,
The above effects can be obtained with a wide range of facsimile machines.

Thirdly, immediately after the recovery from the call-disabled state, it is possible to receive the information that the sender tried to send when the call could not be received without disturbing the human hand. It is possible to reduce the delay in acquisition and prevent the occurrence of extra work.
