Abstract

PURPOSE:To receive automatically only a specific traffic mode by the mode selecting operation, by performing an automatic receiving with respect to a preliminary set specific traffic mode in a facsimile terminal equipment of multimode. CONSTITUTION:An automatic/manual shifting switch 12 sets the output of a flip-flop 15 to an automatic receiving state. A traffic mode shifting switch 13 sets the output of a flip-flop 16 to an H. An automatic receiving mode shifting switch 14 sets a flip-flop 17 to an L. Thus, a GII mode becomes the automatic receiving state. If the output of the flip-flop 17 is set to a reverse H, the output of an exclusive OR gate 18 becomes the H when the output of the flip-flop 16 is the L (mini mode), it becomes the L when the output is H (GII mode). Therefore, the automatic reception is performed by the mini mode.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to facsimile machines, and in particular to automatic reception control of facsimile machines having several communication modes with different control sequences.
In addition to the G111 machine, a simple facsimile machine called a mini-fax was recently developed by Japan's Telecommunications Corporation. Multi-mode facsimile machines with multi-mode facsimile devices have begun to be commercialized, but in the Mini 7 Ax mode (hereinafter referred to as Mini mode), the control sequence at the start of communication is simpler than in the GM and G11l modes. Therefore, when the aforementioned multi-mode facsimile machine automatic reception function is added, the following problem occurs. This problem is shown in Fig. 1 axis) (b), respectively.
This will be explained with reference to the control sequence of the M standard.

That is, in Fig. 1, mini mode (, Fig. 1(a)
) or GII mode ((b) in the same figure), when the receiver receives a calling signal from the sender, it first sends a CED (Called Party Confirmation) signal to the sender, but after that, In Mini mode F, the device immediately enters a phase signal reception standby state after sending the above CED signal, but in Gn mode, the Gl (group identification) signal is sent following the above CED signal, and then it responds to this. After receiving a GC (group command) signal, it enters the above-mentioned phase signal standby state. Therefore, in the multi-mode facsimile machine as described above, when a paging signal arrives due to a call from the sending side, the telephone line is automatically switched to the facsimile side in response to the paging signal, and the CED Even if it is possible to send out a signal, should I send out a Gl signal next?
It is impossible to judge whether to wait for the phase signal, and automatic reception becomes impossible.
1.1.11) This applies not only to the case where a communication mode other than ko:h is provided.

Therefore, the present invention is to enable automatic reception only in a specific communication mode by a mode selection operation in a multi-mode facsimile machine as described above.An embodiment of the present invention is shown in FIG. I will explain about it. In this example, (1) is the NCU (time 111jJ
ll unit), and this NCU has a line connection terminal (2
), a circuit a that switches and connects the telephone line connected to the telephone side (T) and facsimile side (F), a VJ switching circuit (3), and a detection circuit for a ring signal (ring tone signal) from the calling side. (4) and its detection output is the first AND gate (5)
Latch circuit (6) (this (4) + 5
The circuit (7) containing 1 (6) is particularly referred to as the automatic call receiving circuit)
It is equipped with

Next, (8) is a modem circuit that modulates and demodulates the image signal and control signal, (9) is an image signal processing circuit that performs waveform shaping and amplification of the demodulated image signal, and U [ is a recording device equipped with a sirial head, etc. circuit, and each circuit costs one pay. ,
・:'y-v-qi1. It is controlled by: 11. Further, this control circuit I is connected to the NCU (
Switching of the line switching circuit (3) in 1) and the above-mentioned CED
It is designed to create and detect various control signals such as , GI, and GC signals, but the point here is that certain operations can be switched between GI [mode and mini mode] by a mode switching signal described later. You should be careful.

Furthermore, (121I/i automatic/manual (reception) changeover switch, (11 is a communication mode changeover switch, I is an automatic reception mode changeover switch, and these are all momentary E type switches, and can be closed once. The corresponding first, second, and third D flip-flops (15) (lf9
It is designed to invert aη. And the second
Each output of the 6th flip-flop a'n becomes the input of the exclusive or gate aFj, and the output of the 27th flip-flop gate 0, whose output is the input of that output and the output of the 17th flip-flop u9, is the above-mentioned output. The first in the automatic call receiving circuit (7)
Also, 12I) is a light emitting diode (D+) that lights up corresponding to the high level circle and 02 level (L) of the output of the 6th AND gate (A), which opens and closes the AND gate (5). (Ih), the 12th point is also the ν of the 27th lip-flop μQ.
1 Light emitting diode (
Ds) (Da) is a communication mode display circuit, (to) is a telephone, and (to) is a manual reception switch.

In the embodiment shown in FIG. 2, only parts directly related to the gist of the present invention are shown, and base parts such as a document reading circuit are not shown.

One embodiment of the present invention is generally configured as described above, and its operation is as follows. (1) In the case of manual reception in both Gn mode and minimote, in this case, the Set the output of the 17 rip-flop u9 to L (low level). Then, the exclusive signal or dart (11
Regardless of the output of the second AND gate 1! The output of J becomes L, which closes the first AND gate (5) in the automatic call receiving circuit (7). Therefore, even if a calling signal (ring tone signal J & The output is not double-checked by the latch circuit (6). Therefore, the output of this latch circuit (6) is L, and therefore, the control circuit aυ is in the standby state for manual reception, that is, the switching circuit (3) is kept in the above-mentioned position until the reception switch (to) is turned on. At this time, the output (L) of the first flip 70 tube 119 causes the output of the sixth AND gate (the output of the 70 tube 119 to become L). , the manual side light emitting diode (D2) in the automatic/manual display circuit C21) is lit.

In such a situation, when the telephone (c) rings due to a ringtone signal from the transmitting side, the operator picks up the telephone and negotiates the communication mode with the transmitting side, and as a result, communicates in GII mode, for example. If it is decided,
Communication mode changeover switch u31111.1: sets the output of the 27th lip/70th tube 1e to H (high level). Then, the 27th lip-flop output causes the light emitting diode (Ds) on the Gll side in the communication mode display circuit 1 circuit c121 to light up to indicate that it is in the GI mode, and also to display the control mode. The circuit controller 1) stands by to perform GII mode control.

Therefore, when the receiving switch is turned on, the control circuit I
switches the line switching circuit 0 in the NCU (1) to the F side, and sends the CED signal created thereafter to the telephone line via the modem circuit (81) and the above switching circuit.

Subsequently, the control circuit Uυ sends out the GI multiplied signal in the same way as the GI multiplied signal, and thereafter proceeds to receive the image signal according to the control sequence K of Gn (FIG. 1(b)).

In addition, when communicating in mini mode, use the communication mode selector switch u3 to select the previous 27th lip prop (
Set the output of L6) to L. Then, in this case, the light emitting diode (D4) on the mini mode side in the communication mode display circuit (22) lights up, and the control circuit I stands by to control the mini mode. After switching the line switching circuit (3) to the F side in the same way as described above, the receiving operation is performed according to the control sequence shown in FIG. 1(a).
:' (n) When the cm mode is 1 movement reception and the mini mode is manual reception, in this case, the 17th
At the same time, the output of the 27th lip-flop qe is set to H by the communication mode changeover switch (13), and the output of the 67th lip-flop (17) is set to H by the automatic reception mode changeover switch I.
If you set the output of
Since the outputs of 9 are both H, the output of the 6th AND gate is also H. When the light emitting diode (Dl) on the automatic side of the automatic/manual display circuit Qυ lights up, the output of the 27th lip-flop Since the output of (16) is also H, the light emitting diode (I) on the GI side in the communication mode display circuit (221)
) is also lit.

Therefore, this indicates that the Gl mode is set to the automatic reception state.

In the praying state, if the transmitting side is a Gll machine, when a ring tone signal arrives from the transmitting side, this signal passes through the line switching circuit (3) as described above and rings the bell of the telephone (C). Both signals are detected by the ring tone detection circuit (4). In this case, the output of the second AND gate is H as in the sixth AND gate (Gll) described above, which causes the first AND gate (5) in the automatic call receiving circuit (7) to open. Therefore, this 1st. The detection output is passed through an AND gate and latched by a latch circuit (6). This latch output (IN) is the control circuit 1
11), this control circuit 0υ switches the line switching circuit (3) to the F side, and at this time, the output of the 27th lip and 70th lip (Ie is H and the control circuit (11)
Since it is in the GII mode standby state, it immediately sends out the CHD signal and enters the GI [mode control sequence. Therefore, communication with the Gll machine on the transmitting side is established, and image signals are subsequently received.

Next, when the sending side is a mini-fax, the output of the 27th lip/70th lip is set to L by using the communication mode changeover switch 0. At this time, the output of the 67th lip-flop aη continues to be in the H state. Then, the output of the exclusive or gate α becomes L and the output of the second and third AND gate (2) also becomes L, so the first AND gate (5) is closed, and therefore the above (I ), it enters manual reception mode. And at this time, the second
Since the output of the 7-rip-flop (16) is low, the control circuit (Iυ is in the mini-mode standby state IIK). Therefore, in this case, manual reception in the mini-mode as described above must be performed. Also, in this state, one of the diodes (D2) and (D4) in the display circuit υ@ lights up, indicating that the mini mode manual receipt sK is set.

(01) If the mini mode is automatic reception and the GI [mode is manual reception] In this case, the output of the 17th lip and 70th lip u5 will be as described above (
As in the case of (n), set it to H (automatic receipt!1i1), but the output of the 67th lip/70th tube (17) is set to H, which is the opposite of the case of (n) above. I'll keep it.

Then, in this case, i
), it is exactly the opposite of the case, and the automatic reception is GI in mini mode.
This means that manual reception is performed in I mode. Further, each state is displayed by the display circuit υ@ in the same manner as described above.

In addition, in the operations in each case of (I) to (8) above, the E'OM (image signal end) signal from the transmitting side is sent to the control circuit aυ.
When detected, the control circuit Uυ sends out an MCF (completion confirmation) signal and then switches the line switching circuit (3) to the T side to return to the initial state, but the point of refusal is exactly the same as in the conventional case.

Finally, the various operating modes explained so far are summarized as shown in FIG. 3.

As detailed above, according to the present invention, the control sequence is different! Since the multi-mode 7-axis device is configured to perform automatic reception for a specific communication mode set in advance, automatic reception of this type of 7-axis device is possible, and the selection of the specific mode described above is also possible. You can receive m# in that mode just by operating it. , 1", which can be realized at low cost with a very simple configuration.
