Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile device that can connect a plurality of communication lines.

[Prior Art] Generally, in offices and the like equipped with a private branch exchange network, two types of telephone lines are often used: an extension line from the private branch exchange and an outside line from the central office. Both extension and outside lines are connected and the operator makes a selection.

Alternatively, a facsimile device is known that executes facsimile communication using one line that receives a call.

[Problems to be Solved by the Invention] Conventionally, facsimile devices that connect two lines have been unable to communicate with a telephone while one line is performing facsimile communication, even if the other line is idle. There was a problem in that multiple lines could not be used effectively because calls could not be made.

SUMMARY OF THE INVENTION An object of the present invention is to provide a facsimile apparatus that can solve the above-mentioned problems and effectively utilize multiple lines.

[Means for Solving the Problems] To this end, the present invention provides a method for connecting a telephone to another line that is not in use during an incoming call or facsimile communication using a selected line among a plurality of communication lines. This is what I did. Additionally, if a call is received on another line and a ringing signal is being received at the end of a facsimile communication in which a conversation request is being made, the conversation request is invalidated, the communication is ended, and the line is answered immediately. I am trying to carry out facsimile communication.

[Function] Since the telephone can be used normally during facsimile communication, multiple lines can be used effectively. Further, even if a conversation request is made at the end of facsimile communication, if a call is received on another line, the facsimile communication is immediately answered and facsimile communication is executed, so that facsimile communication can be carried out efficiently.

91) - The control unit 87 controls switching of the relay contacts 82, 84-86, and the input port 88 is connected to the calling signal detection circuit 81. The 7/1/1 control section 87 and the input boat 8B, which input the detection signal from a3 and the hook signal from the telephone 9, are both connected to the signal bus 12. Although not shown, the network control device 8 includes, in addition to the above-mentioned circuit, a telephone line 11. A circuit and the like for sending out a selection signal, which is the telephone number of the destination party, is disposed at L and 2.

With the above configuration, in this embodiment, the telephone line 1.1 is connected to an external line from the central office, and the telephone line 1.1 is connected to an extension line from the private branch exchange, respectively, and a facsimile machine is used. In the standby state of this facsimile machine, there are 9 relays and 8 contacts.
2. The common terminals 01 to c4 of 84-86 are all connected to the break side terminals S to B4.Thereby, the telephone 9 is connected to the telephone line 1, 1, that is, the outside line side, and the operator 1 node is , the telephone 9 can be taken off-hook and calls and calls can be made as desired.

In addition, when making a call to send or receive a manuscript, the operator inputs the destination, and if necessary, performs setting operations such as requesting a conversation, as well as external and internal lines, that is, telephone lines L1 and L2.
Perform the selection operation and perform the startup operation.

This facsimile machine starts a predetermined operation when the above activation operation is performed or when a call is received. In other words, Figure 2 (
Figures a) and (b) show this operation, and this facsimile machine constantly detects incoming calls and detects activation operations (process 101. From N in process 101, process 102;
(Proceed to process 101 from N in process 102).

Then, when a call arrives on the telephone line L1 or L2 (Y in process 101), or when the operator performs a startup operation (Y in process 102), the telephone line LL, L2
The line selected by the incoming call or operator is determined. Now, if the line in use is line La and the free line is line Lb, then the line L
The a side is connected to the modem 10, and the line Lb side is connected to the telephone set 9. For example, if the telephone line LL is the line being used, the relay contact 82 is connected to the make side terminal

side, the relay contact 84 is connected to the break side terminal b2 side, respectively. Furthermore, if the telephone line L2 is the line in use, the relay contact 82 is connected to the break side terminal.

, the relay contact 85 is connected to the break side terminal, the relay contact 84 is connected to the make side terminal lI2 side, and the relay contact 86 is connected to the make side terminal -4 side (process 103 and process 104).

As a result, in the case of a single call, the modem 10 sends and receives a facsimile signal after the other party responds by sending out a single selection signal, and in the case of an incoming call, the modem 10 immediately sends and receives facsimile signals to perform the respective predetermined facsimile communications. Start (process 105).

After this, until the facsimile communication is finished, ILt! Machine 9
(Process 106.N of Process 106)
, process 107, and process 106 from N of process 107). Assuming that the communication ends while the telephone 9 remains on-hook (Y in process 107), at that point, the line Lb side receives a ringing signal and checks whether the telephone 9 is ringing (process 108). , and if ringing is not in progress (N in process 108), then it is determined whether or not a conversation request is being made in the facsimile communication (process 109), and if no conversation request is being made (process 1).
09N), connect all the relay contacts 82, 84 to 86 to the break side terminals b1 to b, and connect the telephone lines L1 and L.
The process 110) is performed to disconnect the device 2 and put it into an initial standby state.

On the other hand, in the above case, if a conversation request is made on the calling side or the called side (Y in process 109), after outputting an operator call tone from a speaker (not shown) (process 111), the telephone 9 is activated for a certain period of time. The hook state is monitored (Process 112, from N in Process 112 to Process 113, from N in Process 113 to Process 112).

When the operator wants to have a conversation, he takes the telephone 9 off-hook and presses a stop key (not shown).

When telephone 9 goes off-hook, the facsimile machine (
Step 113 Y), the stop operation should be monitored 41
14), if the stop operation is not performed (processing 114
(N), the process returns to the above process 112.

Here, if a stop operation is performed (Y in process 114)
), switch the telephone 9 to the line La side. That is, in the above, assuming that facsimile communication is being carried out using the telephone line L1, the relay contact 85 is switched to the break side terminal A, and the relay contact 82 is switched to the B8 side. Furthermore, if facsimile communication is being carried out using the telephone line L2, the relay contact 85 is connected to the make side terminal ffIJ.

Switch the relay contacts 84 to the b2 side (processing 1)
15), This allows the operator to have a conversation with the other party using the m filling machine 9.

After this, the hook status of the telephone 9 is monitored (loop of N in process 116), and when it becomes on-hook (process 116
Y), separate telephone lines Ll and L2 11O)
, to the initial state.

Furthermore, if the telephone 9 is not off-hook or stopped in response to the operator call, and a certain period of time has elapsed (Y in process 112), the process immediately returns to the initial state (proceeds to process 110).

Furthermore, one line when the facsimile communication ends! , when a call arrives at side b and the telephone 9 is outputting a ringing sound (Y in process 108), it immediately returns to the initial state (proceeds to process 110) in the same way as above. The device then immediately connects its line 1. In response to side b, the facsimile communication described above is started.

By the way, after the start of facsimile communication (a), the operator can use the telephone 9 as desired. When telephone 9 is thus taken off-hook for use (processing 1
06 Y), during subsequent facsimile communication execution, monitor whether on-hook occurs (process 118, process 118
117). If on-hook occurs (Y in process 117), the process returns to process 107.

On the other hand, if the facsimile machine terminates with an off-footer (Y in process 118), it is determined whether or not a conversation request has been made (process 119), and if no conversation request has been made (process 119). N).

Disconnect the modem 10 from the line La side. In other words,
Time 1) If liLa is the telephone line 141, switch the relay contact a2 to the break side terminal 1, and also switch the line 1. If a is a telephone line 1 or 2, then s1
Switch the contact 84 to the node b8 side (
Process 120).

After this, in the same way as above, the telephone 9 waits for the on-hook period (process 11G N loop), and when off-hook, disconnects the telephone lines LX and L2 (process 110).
, enter the initial standby state.

Also, in the above, if a conversation request is made (
Y in process 119), after the operator 1 outputs the no-call call (process 120), the hook state and stop operation of the telephone 9 are monitored for a certain period of time (processes 121 to 123).
). Here, when the telephone 9 is off-hook (V in process 1Z2) and the switch key is operated (Y in process 123),
), the telephone 9 is switched to the line La side and placed in a talking state (proceed to process 115).

As described above, in this embodiment, during facsimile communication, the telephone 9 is switched to a line that is not in use, so the telephone can be used at any time, and the two lines can be used effectively. can.

Further, even if a conversation request is made at the end of facsimile communication, if a call is received on the other line, the facsimile communication is immediately answered and facsimile communication is executed, so that facsimile communication can be carried out efficiently.

By the way, the telephone 9 can be connected to an outside line or an extension, so when a user using the telephone number 9 uses the telephone 9, especially if the telephone 9 is far from the main body of the facsimile machine, There is a problem in that it is not easy to determine which line it is connected to.

Therefore, the above problem can be prevented by connecting the telephone 9 to one line only when no facsimile communication is being performed on that line, and not connecting to the other line. .

In the first embodiment, an example has been described in which two telephone lines, an extension line and an outside line, are used as communication lines, but it is also possible to use two lines for only one side.

In addition, if you use more than 53 lines, you may be required to connect your telephone to the other line while faxing on one line.
, D, the present invention can be similarly applied and similar effects can be obtained.

Additionally, if the facsimile machine displays the type of line being used during facsimile communication or calls using i'll [9], the operator can easily grasp the line usage status. [Effects of the Invention] As described above, according to the present invention, during facsimile communication, the telephone is switched to a line that is not in use, so the telephone is normally connected to a line that is not in use. This allows multiple lines to be used effectively. Furthermore, even if a conversation request is made at the end of a facsimile communication, if a call is received on another line, the call will be answered immediately and the facsimile communication will be executed, so facsimile communication can be carried out efficiently. 7
