Abstract

PURPOSE:To prevent noise by a bell tone of redialing by requesting the transmission of a telephone number and disconnecting the line automatically even if a call comes from an idle extension or an external line during facsimile communication. CONSTITUTION:When a call with automatic calling is given from an idle extension while the facsimile device is under communication with other device on the external line, a telephone number requesting bit is set to a prescribed position of a non-standard procedure signal NSF to the other device. The opposite device transmits a non-standard procedure step-up signal NSS, informs the signal while adding telephone number information in the signal NSS, outputs a line disconnection instruction DCN and then interrupts the line. The own device stores the telephone number in the signal NSS. Further, the stored telephone number is dialed after the end of transmission.

Description

[Detailed description of the invention] [Technical field of invention] The present invention relates to a facsimile polling method.

In particular, if the other party's facsimile machine is communicating with another facsimile machine when a call such as a transmission request is made from the other party's facsimile machine, and the document cannot be sent to the other party's facsimile machine, the telephone number of the other party's facsimile machine is The reception is memorized, and after the current communication ends,
The system polls the facsimile machine of the other party.

[Conventional technology and problems]

In recent years, multi-functional high-speed facsimile machines have been put into practical use, with automatic switching between internal and external lines.

Devices with automatic dialing functions are becoming more common.

By the way, while various functions have been enhanced in this way,

New issues have also been raised, including:

Many facsimile machines with an automatic call function have a redial function, but even if the other party's facsimile machine is malfunctioning, the call is automatically dialed, so the receiving party suffers from the noise of the telephone ringing. ing.

Furthermore, facsimile machines having an automatic switching function between internal and external lines also have similar problems. If the automatic internal/external line switching function is used, the internal/external line will be connected to the telephone when the internal/external line is being used for facsimile communication.

When an outside line is called using another facsimile machine with automatic dialing, the automatic dialing redial function repeats the dialing over and over again, and the receiving party is bothered by the ringing noise of the telephone.

This is also the case when facsimile communication is carried out using an outside line, and there is a problem in which the user is bothered by the ring noise of the telephone connected to the extension line.

[Object of the Invention] ゛An object of the present invention is to provide a facsimile machine having an automatic dialing function and an automatic internal/external line switching function that can automatically retrieve the telephone number of the other party's facsimile machine without having to worry about the above-mentioned telephone ringing noise. To provide a facsimile polling method which can be memorized and later send a transmission request to the other party's facsimile apparatus, thereby achieving more efficient facsimile communication.

[Structure of the invention]

In order to achieve this object, the facsimile polling method of the present invention allows a facsimile machine equipped with an automatic internal/external line switching function that automatically switches between internal and external lines, and an automatic dialing function that automatically makes a call to the other party's facsimile. +)
automatic call detection means for detecting whether the device is making an automatic call or manual call; a telephone number request means for requesting the other party's factor-clearing device to send a telephone number; and retaining the telephone number sent in response to this request. Equipped with a telephone number holding means, when the own facsimile machine receives a call from another facsimile machine on an external line or internal line while communicating with an external line or internal line, if the called party's facsimile machine is in automatic dialing mode, it will answer and call the other party. Set the phone number of the facsimile machine to send, memorize this phone number, instruct the transmission reservation, temporarily end the communication, wait until the facsimile communication on the outside line or extension is finished, and then call the memorized phone number. ,
The present invention is characterized in that polling transmission is performed to the other party's facsimile machine.

[Embodiments of the invention]

Before describing the present invention in detail based on one embodiment.

The outline will be explained with reference to FIGS. 1 and 2.

For example, when a facsimile machine is communicating with another facsimile machine over an outside line and a call is received from the extension line,
When this call is an automatic call, as shown in Figure 1 (, CN
The G signal is transmitted at intervals of 6 seconds for approximately 0.5 seconds, so this is detected, and as shown in Figure 2, a non-standard procedure (Non-8 standard Fa
cilitea) A telephone number request bit (not shown) is set at a predetermined position of the signal NSF.

In response to this request bit, the other party's facsimile machine performs non-standard j11 [step up (Non-8 standard
FacH-iteS' 5tep-up) signal NS
S is sent, phone number information is added to this NSS and notified, and then a line disconnect command (Disconnect) is sent.
) Output DCN and disconnect 9 lines. The own facsimile machine stores this telephone number in N88. Thereafter, the user waits for the current communication on the outside line to end, dials the stored telephone number (in this case, an extension), and performs polling reception from the facsimile machine that made the call.

An embodiment of the present invention will be described with reference to a map with reference to FIG.

In the figure, 1 is a reading section that reads the original to be transmitted, 2 is a band compression section that compresses the image data output from the reading section 1 using, for example, the Modify No. 7 Man method, and 3 is a recording section. 4 is a band expansion unit that restores the received compressed signal to the original image data; 5 is a transmission control unit that prints out the received image data; 5 is a transmission control unit that outputs the received image data; A telephone number request circuit 5-0 that outputs a signal for requesting number transmission.

6 is a first modem section that modulates and demodulates signals for the outside line; 7 is a second modem section that modulates and demodulates signals for the extension line; 8 is a first automatic call detection section that receives calls from the outside line; 9 is a second automatic call detection unit that detects the automatic call signal CNG shown in FIGS. 1 and 2 and determines whether or not the call is automatic. 10 is a network control unit that has automatic calling and automatic answering functions; 11 is a control unit that has a telephone number holding register 11-O that stores the telephone number of the other party's facsimile machine; It is intended to hold the following.

Next, the operation of the present invention will be explained.

(1) In FIG. 6, it is assumed that a document is set on the reading section 1 and facsimile communication is being performed with a facsimile device connected to an extension line. At this time, if there is a call from another facsimile machine from the outside line.

The first automatic call detection unit 8 detects the automatic call signal CNG as shown in FIG.

Also, if CNG cannot be detected (i.e. when making a manual call)
(9) Drives the audio output section (not shown).

Returns a voice response indicating that communication is currently in progress.

(2) As a result, the control section 11 controls the transmission control section 5 to request transmission of the telephone number of the other party's facsimile machine. In response to this control, the transmission control unit 5 controls the telephone number request circuit 5-0 to set a request bit (not shown) in the NSF' non-standard signal to request transmission of a telephone number, and sets this bit in the NSF' non-standard signal. 1 via the modem section 6 and network control section 10 to the other party's facsimile device connected to an outside line.

(3) Upon receiving the telephone number request pit, the other party's facsimile machine notifies the telephone number using the NS8 signal.

As a result, the other party's facsimile machine determines that the transmission reservation has been completed and transmits a line disconnection command DCN. The facsimile machine receives the NS8 signal from the telephone number holding register 11.
-0 stores the telephone number of the other party's facsimile machine.

(4) At this time, the image data read from the reading unit 1 is
The second seventh dem 7. under the control of the transmission control section 5. Network control unit 10
is being sent on the extension line. That is, without interrupting the current communication.

As shown in (1) to (3) above, a transmission reservation sequence is performed for the called party's facsimile machine. On the other hand, the other party's facsimile machine that has made the transmission reservation (that is, notified the telephone number) waits for polling of the facsimile machine, which will be described later, without activating its own re-dial function.

(5) When the previous facsimile communication using the built-in device is completed, the control section 11 transmits the telephone number held in the telephone number holding register 11-0 to the network control section 10, and 10, the other party's facsimile machine is automatically called. That is, the control unit 11 polls (requests for reception) the other party's facsimile device that made the call from the outside line while communicating on the extension line. As a result, the transmission data from the other party's facsimile device can be reliably received.

〔Effect of the invention〕

According to the present invention, even if a call is made from an open extension or outside line while the own facsimile machine is in the middle of facsimile communication with another party, the telephone number is transmitted as described above and the call is automatically disconnected. Not only is the system free from the noise caused by the ringing of the automatic redial dialing, it is also possible to store the telephone number of the polling reservation light, making it possible to carry out very efficient facsimile communications.
