It is composed of a control section (hereinafter referred to as a slave control section) 37, an operation panel 38, and a sounder 39. Although illustrations of the slave units 3-2 to 3-m are omitted, they have the same configuration as the slave unit 3-1.

Here, the transmitting/receiving device 31 transmits and receives audio signals and control signals to and from the base unit 2, and transmits a baseband image signal obtained by reading a document with the scanner 34 using a coder 35 and a modulating section 36. The encoded and modulated image signal is transmitted to the base device 2 via the antenna 30. The changeover switch 32 connects the transmitting/receiving device 31 to either a handset 33 consisting of a transmitter and a handset, or a modulating section 36.

The handset control section 37 controls the handset 3-1 (3-2

7 has, for example, a microcomputer as a main control circuit, and in addition to a circuit for controlling each circuit element constituting the slave unit 3-1 (3-2 to 3-m), it also controls predetermined operations on the operation unit 38. Accordingly, a start instruction signal sending circuit 37a is provided for outputting a start instruction signal for instructing base unit 2 to start facsimile reception. The operation panel 38 includes an operation section 38a for the operator to input instructions to the handset control section 37, and a display section 38b for displaying various information for the operator. Further, the sounder 39 emits a ringing tone or the like. Next, the operation of the facsimile system configured as described above will be explained according to the control procedures of the base unit control section 27 and the slave unit control section 37.

[0016] In the standby state, the master unit control unit 27 operates as shown in FIG.
As shown in FIG. 1, in steps 1a and 1b, the arrival of outgoing signals and the occurrence of incoming calls are repeatedly monitored. Furthermore, in the standby state, the handset controller 37 repeatedly monitors the occurrence of a call and the arrival of a calling signal in steps 2a and 2b as shown in FIG. First, a case where an incoming call occurs in the standby state will be described.

When an incoming call occurs via one of the telephone lines 1-1 to 1-n and this fact is notified to the base unit control unit 27 from the NCU 20, the base unit control unit 27 performs step 1c.
, a calling signal is transmitted via the transmitting/receiving device 25 and the antenna 26 to the handset (hereinafter referred to as handset 3-1) corresponding to the line where the incoming call occurred via the telephone line 1-1. ). Note that the processing in step 1c is performed by the calling means 27a.

The handset controller 37 of the handset 3-1 transmits the calling signal sent from the base unit 2 as described above to the antenna 3.
0 through the transmitting/receiving device 31, it is determined that a calling signal has arrived, and the processing is changed from step 2b to step 2.
Move to c. In step 2c, the handset controller 37 causes the sounder 39 to emit a ringing tone and waits for an off-hook operation.

Here, when the operator notices the ringing sound and performs an off-hook operation by pressing a predetermined button in the operation section 38a, the handset control section 37 shifts the process from step 2c to step 2d, 2d, a response signal is sent to the base unit via the transmitting/receiving device 31 and the antenna 30. Thereafter, the handset controller 37 waits for a switching instruction or an on-hook operation in steps 2e and 2f.

On the other hand, after transmitting the calling signal in step 1c as described above, the base unit control section 27 waits for a response signal to arrive from the destination of the calling signal in step 1d. In this state, as described above, a response signal is sent from the handset controller 37 via the transmitting/receiving device 31 and the antenna 30, and this response signal is transmitted to the antenna 26.
and is received by the transmitting/receiving device 25, and is received by the base unit control unit 2.
7, the base unit control unit 27 determines that a response signal has arrived and shifts the process from step 1d to step 1e. In this step 1e and the next step 1f, the base unit control unit 27 waits for the arrival of a start signal or a call end notification.

In this state, in the base unit control circuit 2, the changeover switches 21-1 to 21-n of the changeover circuit 21 are switched to the transmitting/receiving device 25. Further, in the handset control unit 37, the changeover switch 32 is switched to the handset 33. As a result, handset 3 of handset 3-1
3 is connected to telephone line 1-1,
It is connected to a counterpart terminal connected via a telephone line 1-1 and a public network (not shown). Therefore, for example, if the other party's terminal is a facsimile machine and you are trying to send a facsimile, the other party's terminal will transmit CNG (Ca
lling tone) signal is sent, and this CNG
The signal causes the receiver in the handset 33 to ring. When the operator recognizes that it is facsimile reception by the ringing of the handset and instructs to start facsimile reception using a predetermined button provided on the operation section 38a, the handset control section 37 receives the start instruction. The process moves from step 2e to step 2g. Step 2
In g, the handset controller 37 sends a start signal to the base unit via the transmitting/receiving device 31 and the antenna 30. Thereafter, in step 2h, the handset control section 37 instructs the display section 38b to display "received", and ends the process. In response to this display instruction, the display unit 38b lights up an LED provided to indicate, for example, "received" or displays characters or images on the LCD. This display is canceled by, for example, a reset operation on the operation unit 38a.

[0022] Here, as described above, the base unit control unit 27 waits for the arrival of a start signal or a call end notification in steps 1e and 1f, and as described above, the base unit control unit 27 waits for the arrival of a start signal or a call end notification.
When the start signal is sent from -1, it is assumed that the start signal has arrived and the process moves from step 1e to step 1g. In step 1g, the base unit control unit 27 switches the changeover switch (here, 1-1) corresponding to the telephone line where the incoming call has occurred (
21-1) is switched to the demodulating section 22, and then in step 1h, the demodulating section 22,
The decoder 23 and the output section 24 are caused to perform reception processing. After the reception process is completed, the base unit control unit 27 instructs the NCU 20 to open the line in step 1i, and ends the process.

On the other hand, when the operator of handset 3-1 performs an off-hook operation and a voice arrives from the other party's terminal while the other party's terminal is connected to handset 33,
This is normal telephone communication, and the operator continues to make the call. When the call ends and the operator performs an on-hook operation, the handset controller 37 moves the process from step 2f to step 2i, and in step 2i, sends a call end notification to the parent via the transmitting/receiving device 31 and the antenna 30. After sending it to machine 2, the process ends. In this case, the main unit control unit 2
7 shifts the process from step 1f to step 1i upon arrival of the call end notification output from the handset 3-1 as described above, and in step 1i, instructs the NCU 20 to open the line and then starts the process. finish. next,
A case where a call occurs in a standby state will be explained.

[0024] The slave device (3-1 in this case) operates the operation section 38.
When a call instruction is issued by operating a predetermined button in a, the handset control unit 37 executes the process from step 2a to step 2.
In step 2j, the transmission signal is sent to the base unit 2 via the transmitting/receiving device 31 and the antenna 30. Subsequently, in step 2k, the handset control section 37 waits for the telephone number of the calling party to be input from the operation section 38b, and when the telephone number is input, the process proceeds to step 2. In step 2, the handset controller 37 sends dial information corresponding to the telephone number input in step 2k to the base unit 2 via the transmitting/receiving device 31 and the antenna 30.

In the base unit 2, upon receiving the transmission signal sent from the slave unit 3-1 as described above, the base unit control section 27 shifts the processing from step 1a to step 1j. In step 1j, the base unit control unit 27 captures the dial information sent from the slave unit 3-1 following the outgoing signal via the antenna 26 and the transmitting/receiving device 25, as described above, and then in step 1k, Dial information N
The NCU 20 sends a dial signal according to the dial information to the telephone line 21-1 corresponding to the handset 3-1 where the call has been made. Thereby, a call is made to the other party's terminal via the public network 1-1, and when the other party's terminal responds, the other party's terminal and the handset 33 are connected via the base unit.

[0026] When the other party's terminal responds and is connected in this manner, the operator can continue talking if he or she is performing normal telephone communication. Further, when performing facsimile transmission, an instruction to start facsimile transmission is given by pressing a predetermined button in the operation section 38a.

In this state, the handset controller 37 is waiting for an instruction to start facsimile transmission or an on-hook operation in steps 2m and 2n, and the instruction to start facsimile transmission is issued as described above. Then, the process moves from step 2m to step 2o, and in this step 2o, the changeover switch 32 is switched to the modulation section 36 side. Thereafter, in step 2p, the handset controller 37 controls the scanner 34 according to a well-known general procedure.
, the coder 35 and the modulator 36 to perform transmission processing. When the transmission process is completed, the handset control unit 37 sends a call end notification to the base unit 2 via the transmitting/receiving device 31 and the antenna 30 in step 2i, and then ends the process.

Further, when performing normal telephone communication instead of facsimile transmission, the operator performs an on-hook operation when the telephone communication ends. As a result, the handset controller 37 moves the process from step 2n to step 2i, and in step 2i sends a call end notification to the base unit 2 via the transmitting/receiving device 31 and antenna 30, and then ends the process.

On the other hand, after instructing the NCU 20 to send a dial signal in step 1k, the base unit control unit 27 waits for the call end notification to arrive in step 1, and as described above, the base unit control unit 27 instructs the NCU 20 to send a dial signal. -1, the process moves to step 1i, in which the NCU 20 is instructed to release the line, and then the process ends.

As described above, according to this embodiment, the facsimile system has n telephone lines 1-1 which are wired lines.
, 1-2 ..., 1-n, and m slave units 3 connected to this base unit 2 via wireless lines.
-1, 3-2..., 3-m, and consists of components for facsimile reception (demodulator 22, decoder 2
3, output unit 24, etc.) and the NCU 20 are provided in the base unit 2, and the slave units 3-1 to 3-m are provided with only components for facsimile transmission, that is, a scanner 34, a coder 35, and a modulation unit 36. . As a result, the facsimile handsets 3-1 to 3-m have a simple configuration and are inexpensive. For this reason, even if multiple handsets are installed, the cost of the facsimile system is relatively low, and by installing multiple handsets in this way, one person or a small number of people can use one handset. It can be placed near the user, increasing the convenience of its use. In other words, the user does not have to move much when sending a facsimile, saving time and effort.

[0031]Furthermore, facsimile reception cannot be performed on slave units 3-1 to 3-m, and therefore, when receiving a facsimile, the received document must be retrieved to the installation position of base unit 2, but facsimile reception is not possible. If this occurs, a call is made to the corresponding handset 3-1 to 3-m, and facsimile reception is started on the base unit 2 according to the operator's instructions, so the operator can install the base unit 2 one by one. It is possible to know the occurrence of facsimile reception without going to the location to confirm reception. Note that when a facsimile reception is performed, a message to that effect is displayed on the display unit 38b, so that the fact that a facsimile reception has been received can be indicated even if some time has elapsed since the instruction to start facsimile reception. can also be known more accurately.

Furthermore, since the base unit 2 and the slave units 3-1 to 3-m are connected via a wireless line, the slave units 3-1 to 3-m
If you want to increase the number of -m, you only need to install a new slave unit without any construction work, and it is highly expandable. Next, a second embodiment of the present invention will be described. FIG. 5 is a block diagram showing the configuration of the facsimile system according to this embodiment. In addition, the same parts as in Fig. 1 are given the same symbols,
A detailed explanation thereof will be omitted.

This facsimile system includes a base unit 4 connected to n telephone lines 1-1, 1-2, . m connected handsets 5-1, 5-2..., 5-
It consists of m. Here, base unit 4 and slave unit 5-
1 to 5-m are the base unit 2 and slave units 3-1 to 3- in the facsimile system according to the first embodiment described above.
It has almost the same configuration as m, but the following points are different. That is, the base unit 4 includes a control unit (hereinafter referred to as a base unit control unit) 40 in place of the base unit control unit 27 in the first embodiment. Similar to the base unit control unit 27 in the first embodiment, this base unit control unit 40 has, for example, a microcomputer as a main control circuit, and collectively controls the circuit elements that constitute the base unit 4. When facsimile reception occurs, the base unit control unit 40 notifies the slave units 5-1 to 5-1 to that effect.
A reception notification circuit 40 that notifies one of 5-m
a, and other control procedures are also different. Furthermore, as shown in FIG. 6, the slave units 5-1 to 5-m have a control unit (hereinafter referred to as a slave unit control unit) 50 in place of the slave unit control unit 37 in the first embodiment. Similar to the slave unit control unit 37 in the first embodiment, this slave unit control unit 50 has, for example, a microcomputer as a main control circuit, and controls the circuit elements configuring the slave units 5-1 to 5-m. However, when the handset control section 50 receives a notification that a facsimile has been received from the main device 4, it has a reception notification control means 50a that notifies the user of the fact. ,
Other control procedures are also different. Next, the operation of the facsimile system configured as described above is controlled by the main unit controller 4.
0 and the control procedure of the handset controller 50 will be explained with reference to FIGS. 7 and 8.

[0034] In the standby state, the master unit control unit 40 operates as shown in FIG.
As shown in FIG. 3, in steps 3a and 3b, the arrival of outgoing signals and the occurrence of incoming calls are repeatedly monitored. Furthermore, in the standby state, the handset controller 50 repeatedly monitors the arrival of reception notifications and the occurrence of calls in steps 4a and 4b as shown in FIG.

[0035] When an incoming call occurs in this standby state, the base unit control unit 40 executes the process from step 3b to step 3.
Move to c. In step 3c, the base unit control unit 40 switches the changeover switch (for example, 21-1) corresponding to the telephone line (for example, 1-1) on which the incoming call has occurred to the demodulation unit 22, and then in step 3d, The demodulator 22, decoder 23, and output device 24 are caused to perform reception processing in accordance with a standard procedure. After the reception process is completed, the base unit control unit 40, in step 3e, connects the telephone line (for example, 1
-1) for a slave unit (e.g. 5-1),
After notifying the reception, in step 3f, the NCU 20 is instructed to open the line, and the process ends. Note that the process of step 3e is performed by the reception notification circuit 40a.

Here, as mentioned above, from the base unit 4 to the slave unit 5,
-1, the handset controller 50
moves the process from step 4a to step 4c. In step 4c, the handset control section 50 instructs the display section 38b to display "received" and ends the process. In response to this display instruction, the display unit 38b lights up an LED provided to indicate, for example, "received" or displays characters or images on the LCD. This display, for example,
It is canceled by the reset operation. Note that the process of step 4c is performed by the reception notification control circuit 50a.

On the other hand, the master unit control section 40 and the slave unit control section 5
0 is in the standby state, when a call is made, the base unit control unit 40 and the slave unit control unit 50 perform the same operations as in the first embodiment described above in transition steps 3g to 3f and steps 4d to 4k. Perform the same process as the process.

As described above, according to this embodiment, the same effects as those of the first embodiment can be obtained, and since facsimile reception is automatically performed by the base unit 4 without any operation by the operator, The burden on the operator is further reduced.

In the above embodiment, an example is shown in which the base unit 2 is provided with one printer 24, but the base unit 2 is equipped with a plurality of optional printers 41-1, 41-1,
41-2 may be connected. That is,
When calling signals are generated via some of the plurality of telephone lines 1-1 to 1-n, these calls are transmitted by the NCU 20 to the base unit control unit 40 via the transmitting/receiving device 25. At this time, the base unit control unit 40 responds to the calling signal.
The switch of the switching circuit 21 is switched to the demodulator 2. Therefore, a plurality of image signals are input to the demodulation section 22 and demodulated. A plurality of demodulated image signals are decoded by a decoder 23 and sent to a printer 24 and an optional printer 41.
-1 and 41-2, are temporarily stored in memories provided in these printers, and are printed out. At this time, the parent unit control unit 40 notifies the corresponding slave units 51-1 to 51-n, via the transmitting/receiving device 25, that the facsimile has been received.

In the above embodiment, the base unit 2 and the plurality of slave units 5-1 to 5-n are connected by a wireless line.
These may be connected by wired lines as shown in FIG. Further, as shown in FIG. 10, when the base unit 2 receives a calling signal via one telephone line 1 connected to the base unit 20, the base unit control unit 27 controls all the slave units 5-1 to 5. -n or a predetermined group of handsets 5-1 to 5-n, for example, handset 5.
The call may be made to a group including -1 to 5-5. Furthermore, when the called handset is set to the away mode, the base unit control section 27 may call another handset.
