DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a block diagram showing the overall configuration of a facsimile machine to which an attached telephone (attached telephone and answering machine) according to the present invention is connected.

This facsimile device 1 includes a facsimile device body 2 that is equipped with the original sending and receiving functions of a facsimile, and an NCU that controls the connection between a telephone line 4 and the facsimile device body 2.
(Network control device) Consists of 3. An attached telephone 5 and an answering machine 6 are connected to the NCLJ3. The attached telephone 5 has a general telephone function, and the answering machine 6 has an answering machine recording function.

Note that the answering machine 6 according to the present invention is not particularly limited in model, as long as it has an answering machine recording function such as IC recording or tape recording.

Below, the configuration of each of the above parts will be explained in order.

The facsimile machine body 2 includes this facsimile machine 1.
A CPU 7 is provided to control the entire transmission and reception of the data. CPU
7 performs the control according to an operation program stored in the ROM 8 in advance. The RAM 9 stores various data generated as the operating program progresses.

In addition to this, the facsimile machine body 2 also has a timer part l.
It is equipped with an O1 operating section 11, a modem (modulator/demodulator) 13, a reading device 14, and a recording device 15. The evening/imagination part 10 includes first and second timers for setting a time limit corresponding to the time required for exchanging a response signal with the calling party, and a second timer for setting a time limit corresponding to the recording time of the answering machine 6. Equipped with 3 timers. The types of response signals will be described later.

The operation unit 11 is for performing various manual operations, and includes various keys such as a numeric keypad and function keys. The modem 13 has a function of generating a tone signal corresponding to the telephone number of the other party, and modulates and demodulates the transmitted and received signals. The reading device 14 reads the original image set in the facsimile main body 2 at the time of transmission, converts both read data into a black and white (bright and dark) binary electric signal,
Input to PU7. The recording device 15 prints out the received image data on recording paper at the time of reception.

On the other hand, the configuration of the NCU 3 is as follows. The polarity reversal detection circuit 17 is for detecting polarity reversal when the DC loop on the telephone exchange (not shown) side is closed. Reference numeral 18 denotes an incoming call detection circuit, which detects the presence or absence of a 16 Hz calling signal sent from the telephone exchange via the telephone line 4, and inputs the detection result to the CPU 7. The dial pulse sending circuit 19 sends out a dial pulse corresponding to the telephone number of the other party via the telephone line 4 when the facsimile machine 1 becomes the calling party. This sending operation is controlled by the CPU 7.

A transformer 20 is connected to the modem 13 via an amplifier 20a. The connection between the modem 13 and the telephone line 4 and the connection between the incoming call detection circuit 18 and the telephone line 4 are made by CM.
This is selectively performed by the L relay switch 23. That is, when the CML relay switch 23 is switched to the position a shown by the solid line in the figure, the telephone line 4 and the incoming call detection circuit 18 are connected, while when it is switched to the position b shown by the dotted chain line in the figure, the telephone line 4 is connected to the incoming call detection circuit 18. 4 and the modem 13 are connected via the transformer 20. This switching position control of the CML relay switch 23 is performed by the CPU 7.

The NCU 3 has a first 0H411 that detects the off-hook state (the receiver is picked up!cN) of the attached telephone 5.
In addition to providing an output circuit 24, a second OH detection circuit 25 for detecting an off-hook state (an answering machine recording state) of the answering machine 6 is also provided. A ringing voltage generating circuit 26 is connected to the attached telephone 5 and the answering machine 6 so as to be switchable with the telephone line 4, respectively.

The ringing voltage generation circuit 26 has an input voltage of +24 VDC and a maximum output voltage of +180 Vl]C, which has constant current characteristics.
It consists of a C-DC converter and a switching circuit (both not shown). The calling voltage generation circuit 26 is connected to the CPU 7 to 1.
When a 6Hz ringing command signal is input, a suspicious ringing signal is generated and the attached telephone 5 and answering machine A6 ring, and when the telephone 5 or 6 is off-hook, a 40Hz ringing signal is generated.
Supplies constant current of raIA~50mA. Note that the ringing method may be a bell sound or a buzzing sound.

Switching between the attached telephone 5, the telephone line 4, and the ringing voltage generation circuit 26 is performed by a first position relay switch 27. That is, when the relay switch 27 is switched to the position C shown by the solid line in the figure, the attached telephone 5 and the telephone line 4 are connected; Telephone 5 and ringing voltage generation circuit 26 are connected.

Further, switching between the answering machine 6, the telephone line 4, and the ringing voltage generation circuit 26 is performed by a second position relay switch 28. That is, when the relay switch 28 is switched to the position e shown by the solid line in the figure, the answering machine 6 and the telephone line 4 are
On the other hand, when switching to the position f shown by the dotted chain line in the figure, the answering machine 6 and the ringing voltage generation circuit 26 are connected.
will be connected.

Switching position control of these first and second position relay switches 27 and 28 is controlled by the CPU 7 which receives an on/off footer state detection signal from an OH detection circuit 24 and 25. Therefore, the signal passing through the position relay switch 27 is transferred to the capacitor 21.
One end of the output from the transformer 21 is applied to the modem 13 via the amplifier 21b, and then to the CPL]7. The other end of the output of the transformer 21 is grounded to a ground terminal 21c. Further, the signal passed through the position relay switch 28 is given to the CPU 7 via the calling voltage generation circuit 26.

In the NCU 3 as described above, the switching operation between the telephone line 4, the facsimile machine body 2, the attached telephone 5, and the answering machine 6 is reliably performed by the CML relay switch 23 and the position relay switches 27 and 28. . Note that these relay switches 23, 27, and 28 are usually a,
It has been switched to the standby position indicated by c and e.

Next, the receiving operation of this facsimile machine 1 will be explained according to the flowchart shown in FIG. CP (J7
First, based on the output signal from the incoming call detection circuit 18, the exchange l! ! ! It is determined whether a 16 Hz calling signal has arrived from the telephone line 4 (Sl). After confirming that the call has been received, it is then determined whether the reception mode is set to "no-ring mode" (no-sound receiving mode) (S2), and when this is confirmed, the position relay switch 27.

Here, the setting of the no-speech mode is processed by software.

In addition, when the meter 2 is disconnected from the telephone line 4, these are connected to the ringing voltage generation circuit 26 side, but in this case, the
A driving prohibition command signal is issued from the PU 7 to the calling voltage generating circuit 26 to prohibit its driving. Therefore, along with disconnecting the telephone line 4, 'T E L 1, . 2 will be completely prohibited.

Next, the CPU 7 determines whether or not a predetermined number of call signals (for example, two) have arrived at the incoming call detection circuit 18 (S4), and when this is confirmed, the CM]2 relay iso

, proceeds to a standby state waiting for predetermined input processing (S32)
On the other hand, if it is not the non-sounding mode, the position relay switches 271.28 have been switched to the c and e digits 1, so the process will proceed directly to the standby state.

If the non-sounding mode is determined in step S2, the process directly proceeds to step S4 in the same manner as described above.

When the process shown in step S4 is completed, the CPf Noah again determines whether or not it is in the no-sound mode (S4). , regardless of whether the mode is in the non-sounding mode or not, the process proceeds to step S5 via the stator knob S4.

If it is determined in step S5 that the automatic facsimile reception is not complete, the receiving mode is switched to the normal facsimile automatic reception mode (S40), and the process then proceeds to a standby state waiting for a predetermined input process (S41).

On the other hand, in step S5, when it is confirmed that the non-ringing mode is set, the CNG is transmitted from the calling side via the modem 13.

Specifically, the determination of whether a CNG call has arrived is made by detecting the frequency band of the incoming signal, for example, and if this band is concentrated around 1100 Hz, which is unique to CNG (on the other hand, if the incoming signal is In the case of voice, the frequency band is distributed over a relatively wide range).
It is determined that it is G.

If it is determined in step S6 that there is no incoming 5CNG call, it means that a voice call has been received (in the case of a telephone call from the calling party or in the case of manual facsimile transmission), so in this case, the RA
The response message stored in the M9 is read out and sent to the calling party via the telephone line 4. Here, the response message is ``I'm away at the moment.''

After sending out the response message, it then sends a CHD (line connection command signal) to the calling party (S8), sets the first timer of the timer section 10, and starts its time limit (S9); , sends Dis (digital identification signal) to the calling side (5IO), sets a second timer, and starts its time limit (Sll). Here, the time limits of the first and second timers t+, Lx (however, 1.

On the other hand, if DO3 is not detected, it is presumed that the incoming signal is voice, so the process proceeds to step S13 as shown by A in the figure, and it is determined (detected) whether it is voice. If the voice cannot be detected, it is determined whether the time limit L2 of the second timer has ended (S14);
After confirming that the time has elapsed, it is then determined whether the time limit t1 of the first timer has expired (515). After confirming that the time limit t has ended, step 51
Proceed to step 6, set the third timer, and set the time limit [,
Start. On the other hand, if voice is detected in step S13, the process goes back to step S16.

The reason why we decided to wait for the end of time limits tZ and Ll before proceeding to the subsequent processing is because it is impossible to distinguish between DO3 and voice, and as a result, it is not possible to detect both. After waiting for the elapsed time, the user should be informed that there has been an incoming call from the calling party (as shown in step S17, 1.2 should be sounded. Then, ζ, B in the figure,
As shown in C, time limit 1. ．． 1. The above-mentioned processing will be performed again until each of these times has elapsed. Incidentally, the time limit t is set in G-bi based on the time required to ring the positions I and 2 a predetermined number of times.

When the position knob 517 starts ringing the position I and 2, it is determined whether the position I and 2 are off-hook until the time limit elapses (S18), and it is determined that the position I and 2 have been off-hook. 6172 Then, the CML relay 1, 23 and TE L, and the switching positions of the relay switches 27 and 28 are controlled to disconnect the facsimile machine body 2 from the telephone line 4, and connect the positions I and 2 to the telephone line 4 side. (S70). In this way, the telephone reception state is established.

On the other hand, if it is not off-footed, wait for the time limit t to elapse (S19), read the response message stored in RA and M9, and send it to the calling party (S2).

J is the corresponding J-ru.Thus, after sending out the response message, connect the device body 2 to the telephone line. At the same time, the terminals I and 2 are connected to the telephone line 4 side (S21).

In the above embodiment, the present invention is applied to a facsimile machine equipped with an attached telephone and an answering machine. Of course, the present invention can be similarly applied to facsimile machines.

Calling ■, Φ Emi, The above-described present invention, when the calling party is a facsimile machine,
Since the present invention is configured to shift directly to the facsimile automatic reception mode without causing the attached telephone to ring, the frequency of ringing of the attached telephone can be significantly reduced compared to the above-mentioned conventional example. Therefore, the quietness can be improved, and even when used at night at home, the noise reduction does not become a problem (which is extremely beneficial to the user).
