Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device system comprising a plurality of telephones and a plurality of data communication devices connected via a communication medium.

[Prior Art] A conventional communication system in which a plurality of telephones and a plurality of data communication devices are connected via a plurality of communication media includes, for example, a line and an outside line connected to a facsimile machine and a key telephone. There is a system that includes a main controller that accommodates a large number of lines and controls communication paths between each line.

An example of the configuration of this system is shown in FIG. As shown in FIG. 6, a plurality of button telephones AlO2 to button telephone AlO
4 and facsimile device 110, each has extension 13.
1 to 134, and controls the formation of communication paths between these extensions and the communication paths between the extensions and connected external lines 121 and 122. The main controller 101 also includes a power supply unit that supplies power to the key telephone.

On the other hand, as another example, the line 131 connected to the facsimile machine 110 may be a line different from the other extension lines 132 to 134, and this line is normally set to the outside line 121 or the outside line 1.
22, and the manual disconnection consists of a pair of signal lines configured to be disconnected from the outside line using a device or the like. And button telephones 102 to 104
is the dedicated telephone for the main controller, and line 1 is the connection line.
32 to 134 include one pair of signal lines for control and power supply in addition to the normal line signal line, making a total of two pairs of signal lines.

However, in such a system, the button telephone and facsimile device have no relationship with each other; the facsimile device is simply connected to the control device of the button telephone, and there is no organic connection between them. It's not a thing. Therefore, when the line to the facsimile machine is not in use, the function is limited to the ability to process calls from the key telephone using the facsimile cover line.

[Problems to be Solved by the Invention] For this reason, even when a facsimile machine that is a non-telephone terminal receives information, the user must go to the non-telephone terminal and receive the information each time. There was a drawback that it was impossible to know whether there was a reception or not without checking whether there was a reception or not.

For example, even if you find out that data has been received and go to the facsimile machine to see if the information is addressed to you, there are many cases where the information is addressed to someone else, resulting in a useless action. It was inevitable.

In order to avoid this, in addition to sending data, it is necessary to make a telephone contact using another line and notify the called party that information is being sent or has been sent. Ta.

[Means for Solving the Problems] The present invention has been made for the purpose of solving the above-mentioned problems, and as a means for solving the above-mentioned problems, this embodiment has the following configuration. .

Further, 213 is a call request button press detection circuit which outputs a pulse to the call call display circuit 214 every time the call request button is pressed. 214 makes a "call call" every time a pulse signal is received from the call request button press detection circuit 213.
This is a call display circuit that repeatedly turns on and off the display.
The signal line 221 is energized when the "calling" display is lit. Further, the call display circuit 214 is connected to the control unit 201.
By inputting the display reset signal 222, the "calling" display is forcibly turned off.

Reference numeral 215 denotes a pseudo-bell sound generating circuit that generates a pseudo-bell sound under the control of the control unit 201. This pseudo-bell sound may be generated directly by the pseudo-bell sound generation circuit 215 or may be generated via the speaker circuit 205. Further, 216 is a call switch, which outputs a human power signal to the control unit 201 every time the switch is input.

The telephone outputs a called signal when selected by the line switching circuit 4, and outputs a ringing tone in response to the called signal. When the operator heard this, he turned the telephone handset to 2.
03, a DC loop is formed in the line, and the line switching circuit 4 detects this, detects the response of the telephone, and forms a communication path.

In this embodiment having the above configuration, when image information communication processing is being performed between the facsimile units 152 of the respective control devices 150 on the sending side and the receiving side, from the telephones connected to each device, You can call any telephone of the other party.

First, a general process will be described below when an operator reservation is made to form a communication path between a telephone connected to the transmitting side control device 150 and a telephone on the other party (receiving side).

In this embodiment, this operator call is actually performed after all image information has been sent. When the control circuit 1 receives calling telephone information of the other party from a telephone, which will be described later, after sending all the image information, the control circuit 1 sends a call request signal (for example, PIF, ( A PRI-EOP signal) having a facsimile information field) is transmitted. For example, a 1-byte calling telephone designation area is provided as a PIF signal, and the signal is sent to the other party.When the telephone of the other party responds within a predetermined time and receives a response signal (for example, a PIF signal), a call request is made. A control signal is output to the telephone to generate a pseudo-bell sound, and the corresponding telephone is made to output the pseudo-bell sound.

When the operator responds to this pseudo-bell sound, a DC loop is formed in the line, and it is detected that the call switch 216 has been pressed, the output of the pseudo-bell sound is stopped.
A communication path is formed between the answering telephone and the destination telephone,
Allows calls between both phones.

On the other hand, if an operator call request is received from a telephone connected to the transmitting device while image information is being received, the receiving device receives a call request including the calling telephone information from the transmitting device after receiving the image information. When a signal (for example, a PRI-EOP signal having a PIF (facsimile information field)) is received, the connected telephone specified by the PIF signal is controlled to generate a pseudo-bell tone. When the operator responds by pressing the call button, etc., the output of the pseudo-bell sound to this telephone is stopped, and a signal (for example, PIF signal), connects the connection line and answering telephone, and forms a communication path. In this embodiment, response detection by a telephone is not limited to a response from the telephone that generated the pseudo-bell sound, but also detects a response from another telephone while the pseudo-bell sound is being output. It is assumed that this is a response from the designated called party from another telephone, and a communication path is established with the telephone that has responded.

In addition, if a normal call request signal (such as a PRI-Q signal) that does not include information specifying the telephone to be called is received, all connected telephones will receive a pseudo-bell tone. output.

Next, a case will be described in which an operator call request is received from a telephone connected to the receiving device during image information transmission. The telephone call on the receiving side is made when the reception of one page of the document is completed.

When the control circuit 1 receives a call request signal (for example, a PI'P signal having a PIF (facsimile information field)) containing calling telephone information from a receiving device (60, etc.), control to generate a pseudo-bell tone for connected telephones. When the operator responds by pressing the call button manually, the pseudo-bell sound output to the telephone is stopped, and a signal indicating that the telephone has responded to the other party's device (for example, a PRI -Q signal) to connect the connection line and answering telephone, and form a communication path. In this embodiment, response detection by a telephone is not limited to a response from the telephone that generated the pseudo-bell sound, but also detects a response from another telephone while the pseudo-bell sound is being output. It is assumed that this is a response from the designated called party from another telephone, and a communication path is established with the telephone that has responded.

Additionally, if a normal call request signal (such as a PIF signal) is received that does not include information specifying the telephone to be called, a pseudo-bell tone will be output to all connected telephones. let

On the other hand, the operator reservation designation control of the receiving device at this time is such that when the control circuit 1 receives half-open calling telephone information from a telephone, which will be described later, it should call the destination device after receiving one page of image information. A call request signal containing telephone information (for example, a PIF signal having a PIF (facsimile information field)) is sent out. When the other party's telephone responds within a predetermined time and receives a response signal (for example, a PRP-Q signal), a control signal is output to the telephone that made the call request to generate a pseudo-bell tone, and the corresponding telephone Outputs a pseudo bell sound.

When the operator responds to this pseudo-bell sound, a DC loop is formed in the line, and it is detected that the call switch 216 has been pressed, the output of the pseudo-bell sound is stopped.
A communication path is formed between the answering telephone and the destination telephone to enable communication between the two telephones.

Details of the above operation control will be explained below with reference to the flowcharts of FIGS. 4(A) to 5(f)) and FIG.

First, the control operation of the control device 150, which is the receiving side device shown in FIG. 2, will be explained with reference to FIGS. 4(A) to 4(l).

When the control device 150 is powered on, the process proceeds to step S1, instructs the line switching circuit 4 to open the line 31, and in the subsequent step S2, controls the data transmission control circuit 14 to switch all connected telephones. A reset signal is output to de-energize the call display circuit 214, followed by step S3.
The pseudo bell sound generating circuit 215 is deenergized. Then, in step S4, it is monitored whether a call request is made manually by inputting a one-touch dial or abbreviated dial on the operation unit 22, or whether the handset 203 of the connected telephone is off-hook and a call request is made. If there is a call request, the process proceeds to step S5, and it is checked whether or not the facsimile communication transmission mode is set at this time.If the facsimile communication transmission mode is not set, the process proceeds from step S5 to step S6, and a known predetermined telephone line is set. Performs call processing.

On the other hand, in the case of facsimile transmission mode, step S5
The process then proceeds to step SIO, instructs the line switching circuit 4 to form a DC loop on the line 31 and issue a call request, and connects the line 31 to the hybrid circuit 6. In the subsequent step 5226, a pre-procedure process is executed, and the process proceeds to step 312, where the transmission image information is read from the transmission document set in the reader 1°, and, for example, one page is sent to the recipient. When the transmission of the image information is completed, the process advances to step 313.
A PIP/PIN signal is received and it is checked whether an operator call has been received from the other party. If the operator has not been called, the process advances to step S30, and if the operator has been called, the process advances from step S13 to step S15. In step S15, it is checked whether telephone designation information for any of the connected telephones is included. Specifically, P I P / P I N
It is checked whether the signal contains FIF. If the telephone designation information is included, the process advances from step S15 to step S16, where the connected telephone designated by the received PIF signal is controlled to generate a pseudo-bell tone, and the process advances to step 318.

On the other hand, if a normal call request signal (for example, a PIF signal) is received that does not include information specifying the telephone to be called, the process proceeds to step s17, and all connected telephones are sent a pseudo call request signal. Control is performed to output a bell sound, and the process proceeds to step 318.

In step S18, it is monitored whether the operator responds within a predetermined time, such as by pressing the call button on the telephone that outputs the pseudo-bell sound. Here, if there is no response within the predetermined time, the process advances to step S19, where it is checked whether there is still a document to be sent, such as when there is still a document to be sent on the reader 10, and there is a document to be sent. In this case, step S19 to step S20
The process proceeds to step S12, where the previously energized pseudo-bell sound generating circuit 215 is de-energized to eliminate the pseudo-bell sound, and the process returns to step S12 to continue transmitting the next page. If there is no document to be transmitted, the process advances to step S21, performs a known post-procedure process, and returns to step S2.

On the other hand, if a response such as input of the outgoing call switch 216 is made within a predetermined time, the process advances from step 318 to step S22, where the output of the pseudo-bell sound to the previously activated telephone is stopped, and in step S23 the other party A signal indicating that your phone has responded to the other device (for example, P
RI-Q signal), and in step S24, the connection line and answering telephone are connected to form a communication path, and in step S2
5 to make a call.

In addition, in this embodiment, the response detection by the telephone is as follows:
In addition to the response from the telephone that generated the pseudo-bell sound,
Even if there is a response from another phone while the pseudo ring tone is being output,
It is assumed that this is a response from the designated called party from another telephone that has responded, and a communication path is established with the telephone that has responded. Then, in step S26, the process waits for the call to end and the line to be released, and when the line is released, the process returns to step S1.

On the other hand, if the operator has not been called in step S13, the process advances to step S30, and similarly to step S19, it is checked whether there are any originals to be sent, such as when there are still originals placed on the reader 10. If there is a document to be transmitted, the process returns to step S12 and continues transmitting the next image information.

If it is the last document, the process advances to step S31, where the control signal 221 from the call display circuit 214 of the connected telephone is activated, and it is checked whether there is a call request. If there is no call request, the process advances to step S21 to execute post-procedure processing, and if there is a call request, the process advances to step S32. Then, it is checked whether the call request signal includes information specifying the telephone to be called, and if there is a call destination specified, the call request signal containing the telephone information to be called is sent to the other party's device (for example, step S33). PR with PIF
I-EOP signal).

On the other hand, if the call request signal does not include information specifying the telephone to be called, the process proceeds to step S34, where a normal call request signal (for example, a PRI without FIF) is used.
EOP signal).

Both then proceed to step S35.

In step S35, it is checked whether a response signal (for example, a PIF signal) indicating that the other party's telephone has responded within a predetermined time has been received, and if a response signal is not received within a predetermined time, the process proceeds to step S21. . On the other hand, if a response signal is received within a predetermined time, the process proceeds to step S36, where a control signal is outputted to the telephone that made the call request to generate a pseudo-bell sound, and the corresponding telephone is made to output the pseudo-bell sound. Then, in step S37, it is checked whether the operator responds to the pseudo bell sound within a predetermined time and a DC loop is formed in the line, or whether the call switch 216 is pressed and inputted to respond. If there is no response, the process advances to step S21, and if there is a response, the process advances to step S24.

On the other hand, if there is no call request in step S4, step S4
0, it is checked whether the called detection circuit 28 has detected a call from the line 31 or the like, and if the call has not been detected, the process returns to step S4.

Here, when the called detection circuit 28 detects a called signal, if a telephone that should output a calling signal (should ring a bell) is specified, it connects the designated telephone and the line 31,
Outputs a ring tone from a compatible telephone. Then, in step S41, it is checked whether or not a called signal has been received a predetermined number of times (for example, three times), and if the called signal has not been received, the calling is continued. If the handset 203 is picked up during that time, a communication path is established between the telephone set and the calling party, and a conversation is made.

If the handset 203 is not picked up even after the called signal arrives a predetermined number of times, the process advances from step S41 to step S42, instructs the line switching circuit 4 to respond by forming a DC loop on the line 31, and is connected to the hybrid circuit 6. Then, in the following step S43, it is checked whether or not data is received with a carrier signal, which is facsimile reception. If no carrier signal is detected on the line, it is not a data communication, so it is assumed that the call is a mistake, and the line is opened and restored in step S44, and the process returns to step S4. Note that if other specific processing is determined in step S44, the corresponding processing will be executed.

If it is a data signal in step S43, step S45
Then, pre-procedure processing, such as detection of various device states, is executed, and synchronization processing with the partner device is executed. Then, in the subsequent step S46, a process of receiving image information sent subsequent to the pre-procedure process is executed. At the same time, in step S47, the received information is sent to V27/V2 via the above-mentioned route.
The signal demodulated by the demodulator 16 is sent to the decoding circuit 17 without going through the memory circuit 19, and is printed by the printer 18.
Output. When the reception of the image information is completed, the process advances to step S48, and it is checked whether or not there is an operator call request from the telephone connected to the transmitting device while the image information is being received. Specifically, after receiving the image information, a call request signal (for example, PIF
Check whether a PRI-Q signal (having a PRI-Q signal) is received. Here, if there is an operator call request, step S
The process proceeds to step 50, where it is checked whether the call request signal includes information specifying the telephone to be called. If information identifying the telephone is included, step S5
1, control the connected telephone specified by the PIF signal to energize the pseudo-bell sound generation circuit 215,
Generates a pseudo bell sound. On the other hand, if a normal call request signal (such as a PRI-Q signal) that does not include information specifying the telephone to be called is received, the process advances to step S52, and all connected The telephone is controlled to energize the pseudo-bell sound generating circuit 215 to generate a pseudo-bell sound. The process then proceeds to step S53, where it is determined whether or not the operator has responded to the call via the connected telephone within a predetermined time, such as manually pressing the call button. If there is no response within the predetermined time, the process proceeds to step S54, where the previously energized pseudo-bell sound generation circuit 215 is deenergized to eliminate the pseudo-bell sound, and the process proceeds to step S55. In step S55, it is checked whether or not the last document information has been received, and if it is not the last, step S55 is performed.
46 and continue receiving the next page. If the last document has been received, the process advances to step S56, a known post-procedure process is executed, and the process advances to step S31.

On the other hand, if a response such as manually turning on the outgoing call switch 216 is made within a predetermined time in step S53, the process advances from step 353 to step S60, where the output of the pseudo bell sound to the previously activated telephone is stopped, and step 3
In step S61, a signal (for example, prp (No. H)) indicating that this telephone has responded is sent to the destination device, and in step
At step 2, the connection line and answering telephone are connected to form a communication path, and the process proceeds to step S31.

Further, if there is no operator call request from the other party's device in step 548, the process advances to step S65, and it is checked whether there is a call request from the connected telephone, such as when the call switch 216 is pressed. If there is no call request, the process advances to step S55 to continue the data transmission process, and if there is a call request, the process advances to step S366.

In step S66, it is checked whether or not the call request includes designation information of the called party's telephone. If there is telephone designation information, the process advances to step S67, where the call request signal containing the calling telephone information (for example, if it is FrF PIF signal) is transmitted. Note that designated telephone information is stored in the FIF. Then, the process advances to step S70.

On the other hand, if the call request signal does not include information specifying the telephone to be called, a normal call request signal without PIF (for example, a PIF signal) is transmitted to the destination connection device. Then, the process advances to step S70. Step 3
In step S70, it is checked whether a response signal (for example, a PRI-Q signal) has been received from the partner connection device within a predetermined time, and if it has not been received within a predetermined time, the process advances to step S55. If a response signal has been received within the predetermined time, the process advances to step S71, and the pseudo-bell sound generating circuit 215 of the telephone that has output the call request is activated to generate a pseudo-bell sound. Then, in the following step S72, it is checked whether the call switch has been manually pressed by any of the connected telephones within a predetermined time and the call request button press detection circuit 213 has detected this and notified the connection control device 150. Note that this response may not be valid even from any telephone, but may be valid only from the telephone that generated the pseudo-bell sound.

Here, if there is no response from the telephone and no notification has been received, the process advances to step S54, and if there is an input from the call switch 216, the process advances to step S73. In step S73, the pseudo bell sound generation circuit 215 of this answering telephone
is deenergized, the pseudo bell sound is stopped, and the process proceeds to step S24.

By controlling as described above, it is possible to talk to any telephone even while data is being sent and received, and the recipient can quickly obtain the desired reception information without taking unnecessary actions. .

Next, referring to FIG. 5, the control of the telephone in the above processing by the control device 150 will be explained.

The control unit 201 checks in step 5101 whether the data interface 211 has received a control signal from the data transmission control circuit 14, and if the control signal has not been received, checks in step 5102 whether there is any key input from the keyboard 206. . If there is no key personnel, return to step 5IOI.

Here, if there is a key input from the keyboard 206, the process advances from step 5102 to step 5103, where it is checked whether or not the input is from the call switch 216. If the input is from the call switch 216, the process advances to step 5120, where the call switch 216 is pressed. If it is not human power, the process advances to step 5105 to execute the process corresponding to the key human power, and after the corresponding process is completed, the process returns to step 5101 to prepare for the next key human power. For example, when the handset 203 is off-hook and the telephone number key is input, the corresponding process is performed by the i sound generation circuit 204.
When the call switch 216 manually inputs the other party's phone number, the input number is temporarily held and then output together with the call request signal. etc.

On the other hand, when a control signal from the data transmission control circuit 14 is received, the process proceeds from step 5lot to step 5110, where it is checked whether the received control signal is an activation signal for the call display circuit 214, and If it is an activation signal, the call display circuit 214 is activated in step 5111.
is activated to display "calling", and the process proceeds to step 5115 in preparation for a response such as taking the handset 203 off-hook.

If the received control signal is not an energizing signal for the call display circuit 214, the process advances to step 5112, where it is checked whether or not a deactivation signal for the call display circuit 214 has been received. If so, the process proceeds to step 5113, where the call display circuit 214 is deenergized and the process proceeds to step 51.
Proceed to step 15.

If the received control signal is not a deactivation signal for the call display circuit 214, the process advances to step 5115;
It is checked whether the signal is an energizing signal for the pseudo bell sound generating circuit 215 or not. If it is the activation signal for the pseudo bell sound generation circuit 215, the pseudo bell sound generation circuit 215 is activated in step 5116 to generate a pseudo bell sound, and the process proceeds to step 5120.

If the received control signal is not an energizing signal for the pseudo bell sound generating circuit 215, the process proceeds to step 5117, where it is checked whether a deactivating signal for the pseudo bell sound generating circuit 215 has been received, and the pseudo bell sound generating circuit 215 is deactivated. If it is a signal, step 31
The process proceeds to step 18, where the pseudo bell sound generation circuit 215 is deenergized to stop the pseudo bell sound, and the process proceeds to step 5120.

If the reception control signal is not a deactivation signal for the pseudo bell sound generating circuit 215, the process proceeds to step 5119, where processing corresponding to the reception control signal is executed, and the process proceeds to step 5120. In step 5120, it is checked whether or not the call display circuit 214 is activated. If the call display circuit 214 is not in the call display state, the call flag is reset in step 5140, and the call flag is reset in step 5140.
Proceed to 125. If it is in the call display state, step 51
21, it is checked whether the call flag in the control unit 201 has been reset. If the call call flag has been reset, the call call flag is set in step 5122, the timer flag is reset in the following step 5123, and the control unit 201 (not shown) is set in step 5124.
A predetermined time, for example, a 5 second timer is set in the timer in the step 5125. In step 5125, the current telephone status is sent to the data interface 2 as a control signal.
11 to the data transmission control circuit 14. The telephone status includes a call setting status, a calling telephone number information input status, a call switch input status, and the like.

On the other hand, if the call flag has been reset in step 5121, the process advances to step 5130, where it is checked whether the timer flag has been set. If set, the process advances to step 5125. If it has not been set, the process proceeds to step 5131, where it is checked whether the timer started previously in step 5124 has timed out. If the time has elapsed, the timer flag is set in step 5132, the calling telephone number input is cleared, and the process proceeds to step 5125.

If it is not timed out in step 5131, step 5
The process proceeds to step 135, and it is checked whether or not the designated power for the calling telephone number has ended, and if the power has not ended, the process proceeds to step 5125.
If the manual input has been completed, the input telephone number is stored in the memory in step 5136, a timer flag is set in step 5137, and the process advances to step 5125.

As described above, according to this embodiment, when data is received by the data communication device, the reception can be known from a nearby telephone, and the received data can be quickly retrieved.

As a result, even if the telephone is placed on the desk and the facsimile machine is placed in the corner of the room, the recipient of the information can immediately know that the information has been received while sitting at the desk. The received information can be immediately output.

[Second Embodiment] In the above embodiment, an example in which a "call" is made from a connected telephone has been described, but the system does not need to be a system in which a data transmission device and a telephone terminal are connected; for example, a facsimile device may be used. A configuration may be adopted in which a call request button is disposed in the operation section, and a telephone number is input manually within a predetermined time after pressing the button.

[Third Embodiment] Although the above description has been made regarding an example in which the telephone number of the communication partner is input and the displayed telephone number is specified manually, the present invention is not limited to this. Instead of specifying the recipient's phone, the receiver inputs the name, etc., and the sending or receiving side has a table that associates names and phone numbers, and refers to this table to identify the phone number. Good too. Furthermore, the corresponding name on the phone is 1.
However, if a plurality of phone names are given, one telephone may be specified for each phone number.

If the name is sent to the recipient and there is no corresponding name, the phone corresponding to the name closest to the name can be identified.

By configuring in this way, it is possible to specify by a commonly used name rather than a list of numbers that are difficult to remember, and it is possible to provide an easy-to-use device that does not cause specification errors.

[Fourth Embodiment] Also, in the above explanation, if the telephone to which the call is to be made is not specified, the call is made to a predetermined telephone.
However, the present invention is not limited to this, and if no telephone is specified, all telephones connected to the receiving device are controlled to display this "calling" display. You can. As a result, even if the recipient is not present at a specific telephone position, the recipient can be sure to know that the image information has been received.

[Fifth Embodiment] In the above description, an example has been described in which a call is made after starting data communication, but this is not limited to after starting data communication, and it is also possible to make a call before starting data communication.

In other words, even if the fax machine is set to automatically receive calls,
It is also possible to make a preliminary telephone call that enables a telephone call to be made with a telephone designated by a call request signal from the calling party without entering the data transmission mode.

In this case, after receiving the initial identification signal from the calling side, a call request signal (for example, a PRI-Q signal) containing pre-specified calling telephone information in the PIF is sent, and the receiving side sends a PIF containing the calling telephone information. When a call request signal having a call request signal is received, the specified telephone may generate a ring tone to notify the information recipient.

As a result, information can be transmitted after confirming that the recipient is present, and wasteful transmission can be prevented.

[Effects of the Invention] As explained above, according to the present invention, a person who should receive information can reliably and quickly know that the information has been received, and can quickly obtain information while also reducing waste. This will prevent you from making any strange movements.
