DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments.
FIG. 1 is a diagram showing an embodiment of a facsimile apparatus for realizing the invention according to any one of claims 1 to 4 , wherein FIG. 1 (a) is a configuration diagram thereof, and FIG. Here is a message example.

First, the configuration will be described. In FIG. 1A, a CPU (Central Processing Unit) 11 includes an RO
In accordance with a program stored in an M (Read Only Memory) 12, the entire facsimile apparatus is controlled. A RAM (Random Access Memory) 13 is a CPU 1
1 stores data necessary for the operation and stores image information. The DCR (encoding / decoding device) 14 encodes the image information to be transmitted by a predetermined method, compresses the amount of the information, and restores the encoded received image information to the original image information. The operation port 15 includes various operation keys for the operator to arbitrarily operate the facsimile machine, such as a one-touch dial key and a speed dial key, and various display devices for displaying messages from the facsimile machine to the operator. Has been established. The scanner (reading unit) 16 decomposes the transmission original into pixels at a predetermined resolution, and converts each pixel into a monochrome image signal. The plotter (writing unit) 17 records an image on a recording sheet at the same resolution as the scanner 16 and outputs the image. The modem 18 modulates a transmission signal and demodulates a reception signal.

An NCU (network control unit) 19 forms a line (telephone line or the like) loop for performing facsimile communication or telephone conversation. To this end, the NCU 19 has a telephone line L1,
A line switching relay RY1 for switching and connecting L2 to either the telephone set 20 or the modem 18, a dial transmission relay RY2, a ring detection section 21 for detecting a 16-Hz ringing signal, a hook detection section 22 for detecting an off-hook of the telephone set 20, and the like. Have been.

In the above configuration, the telephone lines L1 and L2 are
A call waiting service subscribed line that interrupts a call received from a second party (second party communication terminal) during communication with a first party (first party communication terminal), and is connected to this line. In the facsimile apparatus according to the present embodiment, when the communication with the first party is facsimile communication, the tone call of the second party is detected by the tone detector 23 as signal detection means .

In this embodiment, the CPU 11 terminates communication.
Functions as means and control unit, when communication with the first party is a facsimile communication, upon detecting the interrupt call from the second party by the tone detector 23, a facsimile communication with the first party Is forcibly terminated, and if the terminated facsimile communication is a transmission, a redial standby state is set. If the reception is a facsimile communication, a message to the effect that facsimile reception is forcibly output. Here, the output message example is shown in FIG.
This message is displayed on the display of the operation port 15 as shown in FIG.

If the communication from the second party is facsimile communication, the CPU 11 does not accept the facsimile communication from the second party and rejects the automatic reception even if it is set to automatic reception. . FIG. 1 (a)
Are controlled by the I / O port 24. Next, the operation of the present embodiment will be described with reference to the flowchart shown in FIG.

First, at the time of transmission, an original is set on the scanner 16 (step S1), and the telephone number of the other party is input from the operation port 15 (step S2), and the image information of the set original is read by the scanner 16 and stored in the RAM 13. It is stored (step S3). At the same time as the image information is stored by inputting the telephone number, the line switching relay RY1 is switched and connected to the modem 18, and the dial transmission relay RY2 is turned on (step S4). Next, when a dial call is made by turning on / off the dial sending relay RY2 (step S5), a response of the other party facsimile is waited for a predetermined time, for example, T1 time (steps S6 and S7). After the relay RY1 is switched and connected to the telephone set 20 and the dial transmission relay RY2 is turned off (step S8), a redial standby state is set.

On the other hand, if there is a response from the other party facsimile in step S6, transmission is started according to a predetermined protocol. Here, in this embodiment, during facsimile communication (step S9), the tone detector 23 monitors the presence or absence of an interruption call from a party other than the current party, that is, the first party, until the end of communication (step S10). If not, the line switching relay RY1 is switched to the telephone set 20 and the dial transmission relay RY is connected.
After 2 is turned off (step S11), the process ends.

On the other hand, if the judgment in step S10 is YES, that is, if an interrupt call is detected by the tone detector 23, the interrupt call detection flag is turned on (step S12), the facsimile transmission to the first party is forcibly terminated, and the line is terminated. Is released (step S13), and it is determined whether the forcibly terminated facsimile communication is transmission or reception (step S14).
Proceeding to 8, the line switching relay RY1 is switched and connected to the telephone 20 side, and the dial sending relay RY2 is turned off.

In the call waiting service, when a receiver (handset) is put down while an interrupt call is coming, a ring tone of 16 Hz is normally made.
For this reason, in facsimile communication in which the handset is kept on-hook, the telephone 20 rings after being forcibly terminated. Next, when receiving,
When a ringing signal of 16 Hz is detected by the ring detection unit 21 and the I / O port 24 (step S15), it is determined whether or not the automatic reception mode is set (step S16). It is determined whether or not the call detection flag is ON, that is, whether or not the current facsimile reception is from the second party (step S17). Here, if the interrupt call detection flag is ON and the facsimile communication is from the second party, the reception is not performed even in the automatic reception mode, and for example, only the bell or buzzer of the telephone 20 rings. .

As described above, whether or not to receive an interrupted facsimile communication is left to the user's discretion, so that the user is notified that a new facsimile communication has been interrupted during the facsimile communication, and the interrupted telephone calls the facsimile. It is possible to impress the user that the communication is the communication and that the first facsimile communication has been interrupted halfway by the interruption telephone.

On the other hand, if it is determined in step S17 that the reception is not from the second party, that is, if the reception is from the first party, the interrupt call detection flag is turned off (step S18) and the line switching relay is turned off. RY1 to modem 1
8 and a dial transmission relay RY2
Is turned on (step S19), a facsimile response is started. That is, after transmitting the facsimile signal from the modem 18 (digital identification signal DIS: Digital Iden)
receiving a transmission command (Digital Command Signal) and a transmission side command (Digital Command Signal).

Simultaneously with the start of reception, the process proceeds to step S9,
As in the transmission, the tone detector 23 monitors the presence / absence of an interrupt call, and when it is detected, the reception is forcibly terminated. However, if it is determined in step S14 that the facsimile communication that has been forcibly terminated is to be received, the line is switched by connecting the line switching relay RY1 to the telephone set 20 and turning off the dial transmission relay RY2 (step S14). S20), an error report as shown in FIG. 1B is displayed and output (step S21), and the process ends. Note that the error report is not limited to the display output by the operation port 15, and may be, for example, a print output using the plotter 17.

As described above, in the present embodiment, the presence or absence of an interrupted call during facsimile communication can be detected, and if there is an interrupted call, the facsimile communication is immediately terminated and the line is released. Calls can be made to interrupted telephones without waiting. Further, in this embodiment, the line is released after detecting the interruption call at the time of transmission and reception, but when the second party by the interruption is facsimile communication, it is determined that the user's intervention is necessary, and the automatic reception is performed. Even in the mode, do not enter facsimile reception, and leave the interrupted facsimile communication to the user,
Making the user aware that a new facsimile communication was interrupted during facsimile communication, and impressing the user that the interrupted call was a facsimile communication and that the first facsimile communication was terminated prematurely by the interrupted call Can be.

Hereinafter, the invention described in claim 5 will be described based on embodiments. Figure 3 is a diagram showing a facsimile apparatus according to an embodiment of the invention described in claim 5. Note that, in the present embodiment, for the same configuration as the above-described example,
The same reference numerals are given and the detailed description is omitted. First,
The configuration will be described. 3, the modem 18 includes a modulation / demodulation circuit 31, a tone transmission circuit 32, a tone detection circuit 33, and the like. Among them, the tone detection circuit 33
Means that communication with the first party (the first destination communication terminal) is
In the case of the ximi communication, the second party (the second party)
Interrupt call from the destination communication terminal). The buzzer sounding unit 34 is a notifying unit that, when an interrupt call is detected, notifies the outside of the apparatus that there is an interrupt call from the second party while facsimile communication with the first party is continued. .

A hook detecting section (operation detecting means) 22
Indicates that the handset is off-hook (predetermined operation state) during the interrupt call notification by the buzzer sounding unit 34.
Is detected. For this purpose, a telephone switching relay RY for detecting off-hook in conjunction with the line switching relay RY1.
3 are provided. When the line switching relay RY1 is switched to the modem 18 side, the telephone switching relay RY3 connects the telephone 20 to the power supply unit Vcc and supplies power to the hook detection unit 22.

The CPU 11 forcibly terminates the facsimile communication with the first party when the off-hook is detected by the hook detector 22 as a control means .
After the termination, the dial transmission relay RY2 generates a hook signal of a call waiting for performing a caller change by OFF-ON as a hooking means in this embodiment. After the pseudo hooking, a communication circuit is formed between the lines L1 and L2 switched to the second party and the handset. This communication circuit includes a line switching relay RY1 and a line switching relay RY1.
And the telephone switching relay RY3 are both switched and connected to the telephone.

Next, the operation of the present embodiment will be described with reference to the flowchart shown in FIG. First, at the time of transmission, an original is set on the scanner 16 (step P1), and the telephone number of the destination is input from the operation port 15 (step P1).
2) The image information of the set document is read by the scanner 16 and stored in the RAM 13 (step P3). At the same time as the image information is stored by inputting the telephone number, the line switching relay RY1 is switched to the modem 18 side, and the dial transmission relay RY2 is turned ON (step P4). At this time, since the telephone 20 is disconnected from the telephone lines L1 and L2 by the line switching relay RY1, the telephone switching relay RY3 is switched and connected to the power supply unit Vcc side to detect a hook. Next, turn on / off the dial transmission relay RY2.
When a dial call is made by turning OFF (step P
5) The response of the other party facsimile is sent for a predetermined time, for example, T1.
After waiting for time (steps P6 and P7), if there is no response, the line switching relay RY1 and the telephone switching relay RY
3 are switched to the telephone 20 side, and after the dial transmission relay RY2 is turned off (step P8), the system enters a redial standby state.

On the other hand, if there is a response from the other party's facsimile in step P6, transmission is started according to a predetermined protocol. Here, in this embodiment, during facsimile communication (step P9), the tone detection circuit 3 determines whether or not there is an interrupt call from a party other than the current party, that is, the first party.
3 until the communication is completed (step P10). If there is no interrupt call, the line switching relay RY1 and the telephone switching relay RY3 are switched to the telephone 20 and the dial transmission relay RY2 is turned off (step P11). , And the process ends.

On the other hand, if the judgment in step P10 is YES, that is, if the interrupt call is detected by the tone detection circuit 33, the buzzer sounding unit 34 is sounded, and the operator is interrupted by a display (LCD) in the operation port 15. (Step P1
2). Then, when the off-hook of the handset by the operator is detected via the hook detection unit 22 (step P13), the transmission is forcibly terminated (step P14), and the pseudo hooking operation of the dial transmission relay RY2 (OFF-
ON), an interrupt call from the second party is captured (step P15). Next, the line switching relay RY1
Then, the telephone switching relay RY3 is connected to the telephone so as to form a communication circuit between the telephone 20 and the telephone lines L1 and L2 (step P16), thereby enabling communication with the second party. Next, it is determined whether the forcibly terminated facsimile communication is transmission or reception (step P17). If the transmission is transmission, a redial standby state is set. If it is received, the process is terminated, and a request for retransmission to the other party is made at the discretion of the operator.

On the other hand, if the determination in step P10 is NO, that is, if an interrupt call is not detected, or if it is detected but is no longer detected because there is no off-hook in step P13, the buzzer sounding unit 34 and the operation port The display of No. 15 is turned off (step P18), and the process returns to step P9. That is,
As long as the operator does not go off-hook, facsimile communication with the first party continues without responding to the interrupt call.

Next, at the time of reception, when a ringing signal of 16 Hz is detected by the ring detector 21 and the I / O port 24 (step P19), if the automatic reception mode is set, the line switching relay RY1 is switched to the modem 18 side. Connection, the dial transmission relay RY2 is turned on, and the telephone switching relay RY3 is switched and connected to the power supply unit Vcc (step P20), and after the facsimile signal is transmitted from the modem 18 (digital identification signal DIS: Digital Identification S).
ignal) (Step P21), receiving is started in response to a transmission-side command (Digital Command Signal (DCS)).

During reception, the same as in transmission, step P9
The following processing is executed, and the presence / absence of an interrupt call is monitored by the tone detection circuit 33.
The reception of the communication is forcibly terminated by the CD display and the detection of the operator off-hook, and after the pseudo hooking by the dial sending relay RY2, both the line switching relay RY1 and the telephone switching relay RY3 are switched and connected to the telephone 20 side to enable a telephone conversation.

As described above, in this embodiment, the facsimile communication is continued unless the handset is off-hook in response to the operator notification by the interruption call, so that the communication can be continued at the user's will, not to mention when the user is not present. it can. In the present embodiment,
When the operator goes off-hook on the handset, the interruption call is automatically caught, so that it is possible to smoothly switch from facsimile communication to call waiting without any special operation.

Further, in this embodiment, since the interrupt call is detected by using the tone detection circuit 33 provided in the modem, the function of the conventional unit can be used effectively and the cost does not increase.
