FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, a control unit 5 is composed of a microprocessor element or the like, and performs overall processing according to a program stored in a ROM unit of the ROM / RAM 1.

The RAM section of the ROM / RAM 1 stores various constants inputted by the operator through the operation section 2,
Dial I such as "line notification" or "destination notification"
Data such as D is also stored here. The control unit 5 reads them as necessary.

The timekeeping section 3 manages time such as communication time. The reading section of the reading section / recording section 4 reads a document, and the recording section reads image signals and device constants. Print out various reports.

The communication unit 8 comprises an NCU (network control unit), a modem, and the like, and is connected to a communication line 10 and to a plurality of telephones 11 via a crosspoint SW. In order to detect a dial transmitted from the dial 11, the dial detecting unit 9 is also connected.

The voice generator 7 provides various kinds of guidance to the communication line 10 or the telephone 11 or the like.

FIG. 2 is a block diagram showing the configuration of the communication unit 7.

Referring to FIG. 1, a call signal generator 21 comprises:
This is to make the connected telephone ring
On and off are controlled by 22 and 23.

The cross point SW 24 is composed of a multi-point analog SW, and controls connection / disconnection by turning on / off each point.

The monitor sections 25 and 26 monitor the lines of the respective telephones and the communication lines, and also monitor the hook states of the respective telephones.

The relays 27 and 28 are for controlling connection and disconnection of each telephone and the communication line.
Reference numerals 9 and 210 are for protecting devices such as a crosspoint SW when each telephone is ringed by the call signal generation unit 21.

A relay 211 controls connection and disconnection between the communication line and the facsimile apparatus, and a relay 212 causes the communication line to transmit a pulse dial.

The detailed operation will be described below with reference to the flowcharts of FIGS.

When the facsimile apparatus is in a standby state, it periodically performs the key check processing shown in FIG. 3 together with processing such as hook check.

First, in S1, a key input check from the operation unit of the main body is performed. If there is no key input, or if there is a key input, but the key is not a line monitor key for monitoring the line state in the check in S2, the process returns to the standby state and other processing is continued.

When the line monitor key is detected, S3
To check the usage status of the communication line. When the communication line is not being used elsewhere, and when the communication line is being used elsewhere, a tone signal (DT tone, etc.) notifying that the line is available from the tone generator, and a tone signal (notifying that the line is being used, respectively) A busy sound is transmitted from the speaker 6.

If the communication line is not used elsewhere,
After the line monitor key is pressed again or a tone signal is emitted for a certain period of time, the process returns to the standby state, and other processes are continued.

If the communication line is in use, a code ID input from the facsimile apparatus main body is monitored in S4.
Here, if the code ID is not detected even after the elapse of the predetermined time, the process returns to the standby state and the processing is continued.

If a code ID from the facsimile apparatus is detected, the code ID is compared with an ID corresponding to each predetermined function.

In step S5, the ID of the "use source notification" request is collated. If the IDs match, in step S11, the voice generating unit 7 determines how the communication line is currently used.
For example, a message “Phone 2 is in use” is output to notify the operator. Then, it returns to the standby state.

If the IDs do not match in S5, the ID of the "destination notification" request is checked in S6,
If they match, the voice generating unit 7 in S12 indicates that the other party currently performing facsimile communication is, for example, "telephone number 0".
Sending to 3-3XXX-XXXX. "
Notify the operator. This destination may be performed by telephone number using the other party's CSI, TSI, and CIG signals as in this example, or if there is data such as an abbreviated name, a response may be made using the destination name.

Even if the other party is not a facsimile but a telephone call, if a call is made, the aforementioned dial detecting unit 9
The dial can be stored and output similarly.

When a call is received, or when the data of the other party cannot be recognized by facsimile communication, "the other party cannot be confirmed" may be output to notify the operator. .

Thereafter, the process returns to the standby state.

If the IDs do not match in S6, the ID of the "communication time notification" request is collated in S7,
If D matches, in S13, the voice generating unit 7 determines how long the current communication line is continuously used.
For example, "call (transmit) for XX minutes" is output and the operator is notified.

If the IDs do not match in S7,
In step S8, the ID of the "telephone reservation" request is collated, and if the IDs match, in step S14, when a call is made, the voice generation unit 7 transmits the call from the voice generating unit 7 via the crosspoint SW 24 to the "line from the telephone 1". There is a request for a conversation. "

At the time of facsimile communication, the PRI-Q or PIP / PIN signal is transmitted at the next timing of transmitting the Q signal or the MCF / RTP / RTN signal, and returns to the standby state.

Here, before connecting the communication line to the telephone 1, if the line disconnection due to the other party's disconnection is detected, or if the facsimile apparatus does not have the telephone reservation function, the telephone (communication) After the end, for example, "The telephone reservation could not be made." Is output to notify the operator.

If the IDs do not match in S8,
In S9, the ID of the “call after communication end” request is collated,
If the IDs match, the speaker 6 is sounded after the current call and facsimile communication are completed in S15,
Signals that the line is available. At this time, the voice generating unit 7 may output, for example, "the call has ended." And notify the operator.

If the IDs do not match in S9,
In S10, the ID of the "forced interruption" request is collated, and if the IDs match, if facsimile communication is performed in S16, the facsimile communication is forcibly interrupted and the line is released.

At this time, by setting priorities in the apparatus in advance, "forced interruption" may not be accepted for telephone calls and facsimile communication by the designated telephone. Further, even when the “forced suspension” is received, an error due to the “forced suspension” may be printed on a communication result report, a communication management report, or the like to notify the operator.

During a call, the voice generator 7 outputs, for example, "There is a use request from a facsimile" via the cross point SW 24 on the line during the call.
Notify the person on the call. Also in this case, the priority order may be set in the device in advance, so that the "forced suspension" may not be accepted for the designated telephone.

Here, if the IDs do not match, I
Ignore the dial as a D error and return to the standby state.

FIG. 4 is a flowchart showing an operation example from a telephone connected to the facsimile machine. When the facsimile apparatus is in the standby state, it periodically performs the hook check processing shown in FIG.

In step S21, the hook status of the connected telephone is checked. If the hook status is on-hook, the process returns to the standby state and the other processes are continued.

When the off-hook is detected in S21, S22
To check the usage status of the communication line. If the communication line is not being used, the relay 27 or 28 is switched to connect the off-hook telephone to the communication line and return to the standby state. In this state, it is possible to make a call from this telephone, etc., and a tone signal (busy sound or the like) indicating that the line is in use is transmitted from the tone generator to the other telephones via the crosspoint SW24. If the communication line is in use (a busy sound is output to the handset), dial input from the telephone is monitored in S23.

In the case of a DTMF signal, the dial is input to the "dial input" via the cross point SW 24 and detected, and in the case of a pulse signal, the line monitor 25
Alternatively, it is detected via 26.

If the dial ID from the telephone is not detected, the process returns to the standby state and continues the processing. If a dial ID is detected from the telephone,
And the ID corresponding to each predetermined function is collated.

In step S24, the ID of the "use source notification" request is compared. If the IDs match, the voice generating unit 7 determines in step S30 how the communication line is currently used.
For example, "telephone 2 is in use" is output to notify the operator.

Thereafter, the processing is once terminated, and dial input monitoring is continued until the telephone goes on-hook. If a communication line becomes available in S22 during that time, the telephone and the communication line are connected.

If the IDs do not match, S
25, the ID of the “destination notification” request is checked, and
If D matches, the voice generating unit 7 in S31 indicates that the other party currently performing facsimile communication is, for example, a "telephone number".
Sending to 03-3XXX-XXXX. "
Notify the operator. This destination may be performed by telephone number using the other party's CSI, TSI, and CIG signals as in this example, or if there is data such as an abbreviated name, a response may be made using the destination name.

Even if the other party is not a facsimile but a telephone call, if a call is made, the aforementioned dial detecting unit 9
The dial can be stored and output similarly.

When a call is received, or when the data of the other party cannot be recognized by facsimile communication, "the other party cannot be confirmed" may be output to notify the operator. .

After that, the process is temporarily terminated, and dial input monitoring is continued until the telephone goes on-hook. If a communication line becomes available in S22 during that time, the telephone and the communication line are connected.

In S26, the ID of the "communication time notification" request
If the IDs match and the IDs match, the voice generating unit 7 determines in S32 how long the current communication line is continuously used, for example, "call (transmit) for XX minutes". Output and notify operator.

After that, the process is terminated once, and the input monitoring of the dial is continued until the telephone goes on-hook. If the communication line becomes available in S22 during that time, the telephone and the communication line are connected.

If the IDs do not match in S26, the ID of the "telephone reservation" request is collated in S27,
When the voice call is made in S33, the voice generation unit 7 outputs the voice signal from the voice generating unit 7 via the cross point SW24 on the line during the voice call.
For example, "There is a request for a conversation continuing from telephone 1."
Output to notify the person on the call.

At the time of facsimile communication, the PRI-Q or PIP / PIN signal is transmitted at the next transmission timing of the Q signal or the MCF / RTP / RTN signal to perform a telephone procedure. After receiving the command, a confirmation sound (such as a tone signal) is returned to the operator, and the operator returns to the standby state.

Here, before connecting the communication line to the telephone 1, if a line disconnection caused by the other party hanging up is detected, or if the facsimile apparatus does not have a telephone reservation function, the telephone (communication) After the end, for example, "The telephone reservation could not be made." Is output to notify the operator.

If the IDs do not match in S27, the ID of the "call after communication end" request is collated in S28, and if the IDs match, the current call is made in S34.
After the facsimile communication is completed, the designated telephone is called by the call signal generation unit 21 to notify that the line is available. At this time, the format of the call signal may be changed in order to distinguish the incoming call from an outside line, or after the off-hook is detected by the voice generating unit 7, for example, "the call has ended" is output to notify the operator. You may make it.

If the IDs do not match in S28, the ID of the "forced interruption" request is checked in S29,
When facsimile communication is performed in step S35, the facsimile communication is forcibly interrupted and a line is connected to the own device.

At this time, by setting priorities in the apparatus in advance, it is possible to prevent the telephone other than the specified telephone from receiving "forced interruption". Further, even when the “forced suspension” is received, an error due to the “forced suspension” may be printed on a communication result report, a communication management report, or the like to notify the operator.

During a call, for example, a message "use request from telephone 1" is output from voice generator 7 via cross point SW 24 on the line during the call to notify the person who is talking. I do. Also in this case, by setting priorities in the apparatus in advance, it is possible to prevent "forcible interruption" from being received for telephones other than the designated telephone.

Here, if the IDs do not match, I
Ignore the dial as a D error and return to the standby state.

In the above-described embodiment, the voice guidance is provided to the handset of the hooked-up telephone and the communication line. However, the voice guidance may be performed by a predetermined tone signal.

Further, if the dial ID from the attached telephone is limited to the pulse system, the means for detecting the DTMF signal can be omitted, so that the number of points of the cross point SW 24 can be reduced correspondingly and the functional components of each of the cross points SW 24 can be reduced. This can be eliminated, which is advantageous in terms of cost, board mounting area, and the like.

When the telephone 11 in FIG. 1 is used as a facsimile apparatus and a signal indicating that the line is being used is detected, for example, at the time of calling, a "forced suspension" dial ID is sent out and the line becomes usable. The same effect can be obtained by confirming that the call has been made and proceeding to the call.
