Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone transfer device, and more particularly to a telephone transfer device for efficiently performing telephone contact associated with facsimile communication.

(Prior Art) After a document is transmitted by facsimile communication, a telephone call may be made in order to give a notice of document delivery or a supplementary explanation of the transmitted document. When such telephone communication is required, the conversation reservation mode can be set in the transmitting station, and after the document is transmitted, the operator of the other station can be called to make the telephone communication.

However, since the operator is called by sounding an alarm or the like provided in the receiving station, when the operator of the receiving station is unfamiliar or when the surrounding noise is loud, a call based on the conversation reservation setting is made. Was hard to reach the operator.

In order to solve such a problem, there has been proposed a facsimile machine in which a voice sent from a calling side (transmission station) is output by using a loudspeaker instead of calling by the alarm sound. 63-151259).

(Problems to be Solved by the Invention) The above-mentioned conventional techniques have the following problems.

In the above-mentioned conventional device, if a message is transmitted with a too loud voice, it will be offensive to surrounding people, and therefore the range of notification by the speaker is limited. Therefore, if the operator is far away from the fax machine, the message will not be delivered.

In addition, the sender who has made a conversation reservation must be on standby by the facsimile device until the transmission of the image information is completed, and the main work is interrupted during the time involved.

In this way, in both the transmitting station and the receiving station,
When trying to have a conversation with each other according to the conversation reservation, there is a problem that the facsimile device is restrained by the facsimile device until the transmission of the image information is finished, which hinders the improvement of office efficiency.

An object of the present invention is to solve the above problems and to provide a telephone transfer device capable of carrying out a conversation even at a seat away from the facsimile device after the end of the facsimile communication.

(Means and Actions for Solving the Problems) The present invention for solving the above problems and achieving the object includes
Dial number storage means for registering dial numbers of extension telephones connected to a private branch exchange, and conversation reservation detection for detecting whether a conversation reservation has been established based on a conversation reservation procedure or a conversation reservation request has been made. Equipped with means,
The present invention is characterized in that a hooking signal is output in response to a detection signal output from the conversation reservation detecting means, and a dial number registered in the dial number storing means is transmitted to call a planned extension telephone. There is.

According to the present invention having the above characteristics, when the conversation reservation request is made and when the conversation reservation request is received, the extension telephone registered in the dial number storage means can be automatically called when the conversation reservation is established. .

Therefore, the side that has transmitted the document can have a conversation at the place where the main work is performed, which is remote from the facsimile machine, and the side that has received the document can also receive a telephone call at a predetermined location, which is remote from the facsimile machine. .

(Example) Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 2 is a system diagram showing a connection between a facsimile machine and an extension telephone.

In the figure, a facsimile machine 1 and an extension telephone 2-
1 to 2-n are connected to a private branch exchange (hereinafter referred to as PBX) 3, and the PBX 3 is connected to a general public line 4.
The PBX 3 responds to various signals to be described later, the general public line 4, the facsimile machine 1, and the extension telephones 2-1 and 2-2.
..., 2-n is connected or opened.

In the above-mentioned configuration, the line connected to the facsimile apparatus 1 is switched to any of the extension telephones 2-1 to 2-n in order to have a conversation with the other station after transmitting the image information based on the conversation reservation. , The extension telephones 2-1 to 2-n are used to have a conversation with the partner station.

FIG. 1 is a functional block diagram of a transmission section of a facsimile apparatus showing the configuration of the main part of the first embodiment of the present invention.

In the figure, an extension telephone number for having a conversation based on a conversation reservation is registered in the dialed number storage unit 5. This telephone number is registered by the operator from an input unit (not shown) at the same time as the conversation reservation request is issued.

In the facsimile apparatus 1, after transmitting the image information, the conversation reservation procedure is executed based on the conversation reservation request. In the conversation reservation procedure, when a conversation reservation request, that is, a procedure interruption signal Pri-EOP is sent from the transmitting station, in response thereto, the procedure interruption acknowledge signal PIP is input from the receiving station via the PBX 3. The conversation reservation establishment detection unit 7 detects the procedure interruption positive signal PIP and recognizes that the conversation reservation has been established.

The hooking signal generator 8 outputs the hooking signal to the PBX 3 in response to the detection signal indicating that the conversation reservation has been established. The hooking signal is a short-time on-hook (loop break) signal. Also, this hooking signal is stored in the dial number storage unit 5.
In response to this signal, the extension number is supplied from the dial number storage unit 5 to the dial number generation unit 6 and sent to the PBX 3.

The PBX 3 holds the connection to the outside line in response to the hooking signal, analyzes the telephone number supplied from the facsimile apparatus 1, and then the corresponding extension telephone, for example, the extension telephone 2-.
The call signal is output to 1. If the extension telephone 2-1 responds, the facsimile device 1 releases the extension telephone line and P
The BX3 releases the outside line hold and switches the connection to the extension telephone.

FIG. 3 is a flow chart showing the operation of the facsimile apparatus in the first embodiment.

In the figure, in step S1, image information is transmitted. When the transmission of the image information is completed, the process proceeds to step S2.

In step S2, it is determined whether or not there is a conversation reservation request, and if a conversation reservation request is made, the process proceeds to step S3.

In step S3, the conversation reservation procedure is executed, that is, the procedure interruption signal Pri-EOP is transmitted.

In step S4, it is determined whether or not the conversation reservation has been established, that is, whether or not the procedure interruption positive signal PIP has been detected. If the procedure interruption positive signal PIP is detected, step S5
To generate a hooking signal. If the procedure interruption affirmation signal PIP is not detected even after the procedure interruption signal Pri-EOP is transmitted a predetermined number of times or more, it is determined that the conversation reservation has not been established, and the processing ends.

Subsequent to the generation of the hooking signal, in step S6, the extension telephone number registered in advance by the operator is read from the dial number storage unit 5, and the dial number is generated based on this.

After this, the PBX 3 calls the extension telephone based on the supplied dialed digits.

As described above, in this embodiment, the number of the extension telephone to be the transfer destination is registered when the instruction of the conversation reservation request is issued. By doing so, the conversation reservation procedure is executed after the transmission of the image information, and when the conversation reservation is established, hooking is performed so that the registered extension telephone can be called.

Next, a second embodiment of the present invention will be described. In the second embodiment, it is possible to deal with the case where the called extension telephone is busy or does not answer.

FIG. 4 is a functional block diagram of an essential part of the second embodiment, and the same reference numerals as those in FIG. 1 indicate the same or equivalent portions.

In the second embodiment, a plurality of extension telephone numbers are registered in the dial numeral storage unit 5, and each telephone number is given a priority.

In the ringing tone detection unit 9, at the same time as calling the extension telephone, the PBX
A ringing tone (ring back tone) output from the facsimile machine 3 is detected. The counter 10 is activated when the ring back tone is detected by the ring back tone detector 9, and counts the number of times the ring back tone is intermittently emitted. When the number of intermittent ringing tones reaches a predetermined number, the counter 10 outputs a count-up signal. In response to the count-up signal, the hooking signal generator 8 outputs the hooking signal twice.

The PBX 3 first releases the hold of the outside line in response to the first hooking signal, and stops outputting the ringing signal for the extension telephone which is currently calling, for example, the extension telephone 2-1 and the ringing tone for the facsimile machine 1.

Then, in response to the subsequent second hooking signal, P
The BX3 outputs the outside line hold signal again.

In response to the second hooking signal, the dialed digit generating unit 6 stores the dialed digits of the extension telephone 2-2 to which the next priority is added to the extension telephone 2-1 which was previously called, in the dialed digit storage unit. Read from 5 and send out. The PBX 3 calls the extension telephone 2-2 based on this dialed number.
If no response is obtained from the extension telephone 2-2, the call is abandoned and the line is released by on-hooking.

In this way, all the registered extension telephones are sequentially called according to the priority order until there is a response from the called party.

In the second embodiment, the criterion for determining whether to call the telephone having the next priority is based on whether or not the intermittent ringing tone is detected for the predetermined number of times. However, the generation time of the ringing tone is measured by the timer, It may be determined whether or not this time has reached the scheduled time. Also, when it is determined that the extension telephone is busy based on the busy tone, the telephone having the next priority may be called in the same manner as in the embodiment.

Next, a third embodiment of the present invention will be described. In the third embodiment, the transfer destination telephone can be selected depending on the time of communication, and the call is forwarded to the telephone for which a response can be surely obtained. Therefore, a plurality of extension telephone numbers and a scheduled time corresponding to each telephone number are stored in the dialed number storage unit 5. An example of information stored in the dialed number storage unit 5 is shown in FIG.

FIG. 5 is a block diagram showing the third embodiment, and shows the main part of the facsimile apparatus 1. The same reference numerals as those in FIG. 1 indicate the same or equivalent parts.

In the figure, when the conversation reservation establishment detection unit 7 detects that the conversation reservation is established, a hooking signal generation unit 8 outputs a hooking signal to the timepiece device 11. Clock device 11
Responds to the hooking signal and outputs the current time to the dialed digit storage unit 5. The dialed number storage unit 5 supplied with the current time searches the stored information (time) for the time closest to the current time. Then, the extension telephone number corresponding to the searched time is output from the dialed digit memory 5 to the dialed digit generator 6.

As described above, in the third embodiment, it is possible to call an extension telephone from which a response can be surely obtained depending on the time, among a plurality of registered telephones.

Although the time is stored in the dial number storage unit 5, the scheduled time zone is registered to detect which time zone the current time belongs to and call the extension telephone corresponding to the time zone. May be.

Next, a fourth embodiment of the present invention will be described. In the third embodiment, a call is made to an extension telephone whose response is likely to be obtained depending on the time or time zone. However, in order to further increase the certainty, in the fourth embodiment, each time or It is now possible to register multiple extension telephone numbers with priority ranking added to the time zone.

An example of information stored in the dialed number storage unit 5 in the fourth embodiment is shown in FIG.

In the fourth embodiment, the time stored in the dial numeral storage unit 5 is searched based on such stored information. Then, the extension telephone having the extension telephone number stored first in the priority order corresponding to the time is called.

If there is a response, you can connect the line and start a conversation,
When there is no response or busy, the extension telephone stored with the second priority is stored. Thereafter, the registered telephones are sequentially called in descending order of priority until a response is received.

The main functions of the fourth embodiment are the same as those of the second embodiment and the third embodiment.
Since it is obtained by combining the functions shown in both of the embodiments, illustration and description are omitted.

As described above, in the first to fourth embodiments, the call of the extension telephone is particularly described as an example. However, the extension station can similarly call the extension telephone.

That is, when the receiving station also detects that there is a conversation reservation request from the transmitting side after receiving the image information, it outputs a hooking signal to the PBX 3 and outputs the planned extension, as described with respect to the transmitting station. You can call the phone.

In order to perform such an operation, the receiving station is provided with a conversation reservation request detecting means as a portion corresponding to the conversation reservation establishment detecting section 7 of the transmitting station. The conversation reservation request detecting means detects that there is a conversation reservation request by the procedure interruption signal Pri-EOP sent from the transmitting station. The hooking signal is output in response to the detection signal of the conversation reservation request.

As described above, by merely replacing the conversation reservation establishment detecting unit 7 with the conversation reservation request detecting means, the receiving station can transfer a telephone call based on the conversation reservation by the same operation as described in the first to fourth embodiments. It can be carried out.

It should be noted that the transmitting station may input and register the extension telephone number when making a conversation reservation request, but the receiving station cannot predict when to receive the telephone number.
It is necessary to previously store the extension telephone number to be transferred.

(Effects of the Invention) As is apparent from the above description, according to the present invention, it is possible for the transmitting station to detect that a conversation reservation has been established and for the receiving station to detect that a conversation reservation request has been made. In this way, the extension telephone can be called in response to each detection signal.

Therefore, by registering the time when the call is relatively reliable and the optimal extension phone, the necessary information accompanying the facsimile communication can be exchanged by the phone without reducing the efficiency of the main business. You can
