Abstract

PURPOSE:To allow transmission of mini-FAX mode on the transferring side against a G3 mode receiver of CCITT recommendation by detecting an initial identification signal from a facsimile on the other party within a fixed period of time, on the basis of which the facsimile starts transmission under a prescribed mode. CONSTITUTION:The facsimile detects whether a mini-FAX mode is selected or not at a control circuit 21 by a mini-FAX button press-down detection circuit 20 and when said mode is detected, the facsimile receives the initial identification signal from the facsimile on the other party by a timer circuit 19 while monitoring a fixed time. This reception is performed at a tonal signal analysis circuit and a binary signal analysis circuit 14. When the initial identification signal is detected within a fixed period of time, the facsimile sends out an command signal for that identification signal, namely a GC2 (Group 2 Command) signal, or NSS (Non-Standard System Setting), DCS (Digital Command Setting) signals, by which the facsimile allows transmission by the mode for the initial identification signal.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile machine, and more particularly to a facsimile machine having a mode in which all signal transmission starts without recognizing an initial identification signal sent from a facsimile machine on the other end. It is something.

[Prior art]

Conventionally, there is a mini-fax mode as a mode in which all signal transmission is started without recognizing the initial identification signal sent from the other party's facsimile machine.

In the mini-fax mode, when transmitting, a phase signal is sent without recognizing the initial identification signal sent from the other party's facsimile machine.

For this reason, the transmitter side cannot determine the mode according to the receiver's capabilities as in the case of normal electric transmission.

For this reason, a switch or the like is usually provided on the panel of the device to determine whether or not to send a mini-fax.

As a result, if transmission in mini-fax mode was selected, phase signal transmission would begin as soon as the start button was pressed.

At this time, if the facsimile machine on the other end did not have the function of communicating in mini-fax mode when the facsimile machine was being sent over the telephone network, a pre-procedure error would occur.

In addition, if the 7mm facsimile equipment on the transmitter and receiver sides had the function of 03 transmission as per the CCJ's recommendations, a major drawback was that a pre-procedure error like the previous one would occur. .

A specific example thereof will be explained with reference to FIG.

Figure 1 shows an example of a pre-procedure procedure in a conventional facsimile machine.The transmitting stage has a mini-Fux mode transmission function and a CCI's 03 Recommendation 03 transmission function, and the receiver has a C (JTT Recommendation) 03 transmission function. It has the 03 electric transmission function.

In the figure, the symbol 1 is an option signal.
Non-standard equipment installation signal CNCI to identify specific user requirements that are outside the scope of the I series recommendations.

The reference numeral 2 is a digital identification signal (DIS) indicating that the called device has the standard functions recommended by CCITT.

The reference number 3 is a phase signal (PI(S)) that is sent out to match the phase on the transmitter side and the phase on the receiver side before the image information is transmitted.

In the pre-procedure shown in Figure 1, the transmitter transmits the PI3 signal after the mini fax is selected and the start button is turned on.
After sending for 0 seconds, it ends with an error.

The receiver also sends the NSF and DIS signals a total of 8 times before ending with an error.

As described above, when the other party's facsimile machine does not have the function of communicating in the mini-fax mode, a pre-procedure error occurs in all cases.

〔the purpose〕

The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology.The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional technology. It is an object of the present invention to provide a facsimile device that can reliably perform electronic transmission in mini-fax mode even if the facsimile device on the receiving side has only the G3 mode recommended by CCITT.

In order to achieve the above object, the present invention provides a facsimile machine having a mode in which signal transmission is started without recognizing the initial identification signal transmitted from the other party's facsimile machine, when this mode is selected.

On the other hand, FIG. 3 shows a block diagram of a control circuit of a facsimile apparatus according to the present invention.

In Fig. 3, the reference numeral 1o indicates a network control device, which is connected to a telephone line and OAK, and in order to use the telephone network for data communication, etc., it controls the connection of the telephone switching network and switches to the data communication path. It also has the function of holding the loop.

This network control device 10 is connected to a transmission/reception switching circuit 11 via a signal line 10b.

For transmission and reception, the switching circuit 11 is connected to a signal line 21a of a controller circuit 21 that controls the system.
If the signal level of +a is "1", signal line 10
b is connected to the signal line 18a side to set the transmission state, and when the signal level is rOJ, the signal line 10b is connected to the signal line 1ea
Connect to and enter reception status.

The transmission/reception switching circuit 11 is connected to a tonal signal analysis circuit 12 via a signal line 11a.

When this circuit receives a non-call station identification (CED) signal, it generates a signal, a pulse at 112a, and a group 2 identification (J2
When the ° (...) signal is received, a pulse is generated in the signal m12b.

Further, the signal 1111a is connected to the demodulator 13 of the CC11''T recommendation 1321, which receives the signal on the signal line 11 and outputs the demodulated result to the binary signal analysis circuit 14 via the signal line 13a. .

This circuit analyzes the binary signal sent from the other party's facsimile machine, and is NSF.

When the DIS signal is received, a pulse signal is generated to the control circuit 21 via the signal il 14a.

On the other hand, the one indicated by reference numeral 15 sends out a phase signal (9 oz + 6 H2 for standard and fine, respectively) in the mini-fax mode via the signal line 15a when a pulse is generated on the signal line 21b.

The one indicated by reference numeral 16 is an OC2 signal sending circuit, and when a pulse is generated on the signal line 21C from the control circuit 21, the signal 1 is output.
Sends a group 2 command (GC2) signal to the tJj 116a 8. Also, what is indicated by reference numeral 17 is the NSS, IX's signal sending circuit, and when a pulse is generated on the signal line 21d from the control circuit 21, the NSS signal is sent to the signal aoa. , This is a circuit that sends out DC8 signals.

On the other hand, what is indicated by the reference numeral 18 is an adder circuit, and the signal line 15a
, (signals of the signal line 17a of the number i l1ilj116a1 are respectively inputted, and the result of adding these signals is output to the transmission/reception switching circuit 11 via the signal line +82.

On the other hand, the reference numeral 19 is a timer circuit, which is used to receive an initial identification signal from the other party's facsimile machine for a certain period of time when the mini-fax mode is selected. signal line 2
After the pulse is generated at 1e, a certain period of time, for example 3
When seconds have elapsed, a pulse is generated in the signal 1ts19a.

Also, the reference numeral 20 is a mini-fax press detection circuit, which detects whether or not the mini-fax mode is selected, and when the mini-fax button is pressed, the signal line 20
The signal level "month" is outputted to the control circuit 21 via the line a, and when the mini-fax button is not pressed, a signal level "0" is outputted to the signal line 20a.

Based on the circuit +114 configuration as described above, the control circuit 21 detects whether or not the mini-fax mode is selected by the mini-fax button press detection circuit 20.

When the mini-fax mode is selected, the timer circuit 19 monitors a certain period of time while receiving the initial identification signal sent from the other party's facsimile machine.

This reception is performed by a tonal signal analysis circuit 12 and a binary signal analysis circuit 13.

If the initial identification signal from the other party's 7mm 7mm device is not detected within a certain period of time, the phase signal sending circuit 15 sends out a phase signal in mini-fax mode.

Furthermore, if an initial identification signal from the other party's facsimile machine is detected within a certain period of time, a command signal for the initial identification signal is sent out.

The GC2 signal sending circuit 16 sends out the GC2 signal, and the N
SF, NSS when TIS signal is detected,
The DC8 signal sending circuit 17 sends out the NSS and DC8 signals.

The specific control performed by the above-mentioned control circuit will be explained with reference to the flowchart shown in FIG.

That is, in step 30 in FIG.
It is determined whether the signal level of 20a is "1", that is, whether the mini-fax button is pressed.

If the button is not pressed, that is, if the signal level of the signal line 20a is "0", the process advances to step 31 and transmission is performed in a mode other than the mini-fax mode.

On the other hand, if the signal level of the signal line 20a is "1", that is, if the mini fax button is pressed, step 32
Proceed to.

In step 32, a timer circuit 19 generates a pulse on the signal line 21 and measures a certain period of time, for example, 3 seconds.
Start.

Then, proceed to step 33.

In step 33, r41 is determined as to whether or not a pulse has occurred on the signal line 19a. If a pulse is generated, this means that the timer circuit 19 has timed out, and the process proceeds to step 34.

In step 34, a pulse is generated on the signal line 21b to send out a phase signal in the mini-fax mode.

The process then proceeds to step 35, where transmission is performed in mini-fax mode.

On the other hand, when it is determined in step 33 that no pulse is generated on the signal line 19a, there is no overtime, so the process proceeds to step 36. In step 36, it is determined whether a pulse is generated on the signal line 12a, that is, whether a CED signal from the other party's facsimile machine has been received.

If a pulse is generated on the signal line 12a, step 32
Return to

On the other hand, if no pulse is generated on the signal line 12F+, the process advances to step 37.

In step 37, it is determined whether or not a pulse has occurred on the signal line 12b, that is, the other party's facsimile equipment signal line 12b.
If a pulse is generated, the process advances to step 38. In step 38, a pulse is generated on the signal line 21c,
In step 39, transmission in G2 mode is performed.

On the other hand, if it is determined in step 37 that no pulse is generated in the signal 112b, the process proceeds to step 4°.

In step 40, it is determined whether or not a pulse is generated on the signal line 14a, that is, the NS signal from the other party's facsimile machine is determined.
It is determined whether or not the DIS signal has been received.

If a pulse is generated on the signal line 14a, step 41
In step 41, a pulse is generated in the signal a2+d to send out the NSS and DC8 signals. Then, the process advances to step 42 to perform transmission in G3 mode.

1, if it is determined in step 40 that no pulse is generated in the signal 1114a, the process returns to step 33.

In this way, when the mini fax mode is selected, if an initial identification signal is detected within a certain period of time due to the configuration that receives the initial 1 identification signal from the 111 re-ac/millimeter device within a certain period of time, the mode for that initial identification signal is set. It is possible to perform electric transmission.

Therefore, even if the other party's facsimile machine does not have the function to transmit in mini-fax mode, but you accidentally select to send in mini-fax mode, it is possible to send an email, making it possible to provide an extremely reliable facsimile machine. .

By the way, in the series of embodiments, when all initial identification signals are detected within a certain period of time, the transmission is performed in the mode corresponding to the initial identification signal, so if the initial identification signal from the other party's facsimile machine is 012, Even (lc
2 will be sent out, and electric transmission will be performed even in the 02 mode.

However, sending an email in [2] mode takes longer than sending in the mini fax mode because there is no fax signal.

Therefore, when an NSF or DIS signal is detected, transmission is performed in G3 mode, and when a G2 signal is detected, transmission is not performed in G2 mode, but in mini-fax mode. Also good.

〔effect〕

As is clear from the above description, according to the present invention.

A timer and an initial identification signal recognition means are provided to receive the initial identification signal from the other party's facsimile machine for a certain period of time, and when the initial identification signal is detected within the certain period of time set by the timer, the initial identification signal is recognized. Since the configuration is such that transmission can be started in signal mode, if the sender mistakenly selects mini fax mode to send data when the other party's facsimile machine does not have the function to send data in mini fax mode. It is also possible to perform electronic transmission, and a highly reliable facsimile machine can be obtained.
