Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine.

[0002]

2. Description of the Related Art Conventionally, a facsimile machine has been used as a device for transmitting and receiving image signals via a telephone line.

Since such a device has been downsized and the price has been reduced, it has become popular in general households. In general household use, since a facsimile machine and a telephone are usually connected to one telephone line, the facsimile machine is provided with a function for connecting the telephone.

In addition, when a call is received while he is away,
An answering machine having a function of recording a message from the calling party by notifying the calling party of the absence is widespread, and a facsimile apparatus having a function of connecting the answering machine also exists. The representative ones of the functions are as follows.

The first is a silence detection function. The function is that the facsimile machine starts communication when the telephone circuit is monitored by the monitor circuit and it is confirmed that there is no sound.

The second is a CNG detection function. The function is that the facsimile machine starts communication when the telephone circuit is monitored by the monitor circuit and CNG is detected.

The third function is that the facsimile machine automatically starts communication when a predetermined time has elapsed since the answering machine received the call.

The fourth function is that the facsimile device automatically starts communication when the telephone circuit is monitored by the monitor circuit and the specific DTMF signal is detected by the remote signal detecting means.

The above functions are activated when the facsimile machine is set to the answering mode and the external answering machine starts sending and recording a message in response to the ring signal when there is an incoming call. .

[0010]

By the way, even if the user is in the absence mode, the user may want to talk directly with the calling party when the user is on the side. However, in the conventional configuration, when the answering machine automatically answers when receiving a call, even if the user picks up the handset of the answering machine to talk to the calling party, the facsimile machine performs the predetermined operation. There was a problem that the call was blocked.

That is, the facsimile machine cannot detect whether the answering machine is answering the call or the user is talking even during the call by the handset. Therefore, for example, when the conversation is interrupted. There was a case where this was detected as silence and switching to facsimile reception. Also, in the voice during conversation, CNG or DTM
If the F signal contains the same frequency component, it may be erroneously detected as a CNG or DTMF signal, and may be forcibly switched to facsimile reception even during a call after a certain period of time. .

The present invention has been made in view of the above-mentioned prior art. Even when the answering mode is set, the user talks with the handset of the answering machine attached to the telephone and responds to the telephone when the ring signal is detected. An object of the present invention is to provide a facsimile device capable of making a call.

[0013]

In order to achieve this object, the facsimile apparatus of the present invention comprises a monitor means for detecting a signal appearing on a telephone line while an off-hook detecting means detects an off-hook of an attached telephone, and a facsimile operation. Facsimile activation signal detection means for activation, control means for controlling the facsimile communication means to perform facsimile reception when a facsimile activation signal is detected,
The detection interruption instructing means and the means for controlling so that the detection of the facsimile activation signal detecting means is interrupted when the detection interruption instructing means issues an interruption instruction.

[0014]

With this structure, even if the facsimile activation signal is detected, the normal conversation can be continued by instructing the detection interruption by the detection interruption instruction means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a facsimile apparatus of the present invention, and FIG. 2 is a flow chart showing its operation.

In FIG. 1, 1 is a telephone line, 2 is a jack for connecting an attached telephone, 3 is a ring signal detecting means for detecting a ring signal input from the telephone line, and 4 is a ring detected by the ring signal detecting means. An interface circuit that closes a telephone line in response to a signal. A monitor circuit 5 detects a signal appearing on the telephone line even while the off-hook of the telephone attached to the jack 2 is connected. 6
Is a facsimile signal sending means, and 7 is a facsimile signal receiving means.

The signal 8 detected by the monitor circuit 5 is CN.
CNG signal detecting means for checking whether or not it is G, and 9 is a signal D detected by the monitor circuit 5 in response to a facsimile start request.
It is a remote signal detecting means for checking whether or not it is a TMF signal. Reference numeral 10 is a silence detecting means for checking whether or not there is silence from the output of the monitor circuit 5. The above CNG signal detecting means 8, remote signal detecting means 9, silence detecting means 10
Is provided as a facsimile activation signal detecting means for activating the facsimile operation.

Reference numeral 11 is an off-hook detecting means for detecting an off-hook of the telephone set attached to the jack 2, 12 is an image reading means, and 13 is a printing means. Reference numeral 14 denotes an operating means, which is provided with a stop button for instructing the interruption of the detection of the facsimile start signal and a receiving mode instructing means for setting the receiving mode. Reference numeral 15 is a timer for measuring the off-hook time to check whether or not a fixed time has elapsed, which is also one of the above-mentioned facsimile activation signal detecting means. Reference numeral 16 denotes a control unit that controls each unit according to each signal, a predetermined procedure (shown in FIG. 2), and a command input by the user via the operation unit 14. Reference numeral 17 denotes a storage unit that stores the story of the reception mode instructed by the reception mode instruction unit.

The operation of the facsimile apparatus configured as described above will be described below.

The receiving mode is instructed from the operating means 14, and the instructed mode is stored in the storage means 17. Here, the reception mode is "answer mode", which indicates that the connected telephone automatically responds even when the user is out by detecting a ring signal on the answering machine, and modes that indicate other states. is there.

The incoming call operation will be described below with reference to FIG. First, the ring signal input from the telephone line 1 is detected by the ring signal detection means 3 and output to the control means 16 (step 1). The control means 16 detects by the off-hook detection means 11 whether the off-hook telephone is off-hook (step 2). When the off-hook is not detected, the ring signal is input a predetermined number of times predetermined (step 3). , Telephone line 1 to interface circuit 4
Are closed (step 4). Next, a facsimile signal receiving operation is started (step 5).

When the off-hook is detected in step 2, the control means 16 causes the monitor circuit 5 to start monitoring the signal on the telephone line 1. In this state, there may be a case where the caller and the user of the additional telephone are talking with each other, or if the answering machine is connected as the additional telephone, the answering machine automatically responds. Since the monitor circuit 5 is connected to the telephone line 1 via a high impedance circuit, it does not affect the communication quality of the caller and the user during a call.

In this state, the remote signal detecting means 9 is operated by the DT.
The MF facsimile instruction signal is monitored (step 6). When the user feels the necessity of receiving a facsimile during a call and presses a specific dial of the side-phone, this signal passes through the monitor circuit 5, is detected by the remote signal detecting means 9 and is output to the control means 16, thereby controlling means. In step 16, the telephone line is closed (step 4) and the facsimile signal is received (step 5).

In this monitor state, it is monitored whether or not the stop button of the operation means 14 is pressed (step 7). If the stop button is not pressed here, it is confirmed that the reception mode stored in the storage means 17 is the absence mode (step 8). If it is the absence mode, the CNG signal detection means 8 detects the detection operation. If the CNG detection is performed or the off-hook of the auxiliary telephone is detected in step 2, the timer 15 starts counting the time and a certain time has elapsed (step 10), or the silence detecting means 10 detects the silence. For example, the telephone line is closed (step 4) and the facsimile signal is received (step 5). Then, the detection of these signals is continued until the on-hook side telephone is hooked (step 12).

When it is detected in step 7 that the stop button has been pressed, steps 9, 10, and 11 are skipped, and the process proceeds to step 12. That is, the CNG signal monitoring in step 9, the monitoring of whether or not a certain time has elapsed in step 10, and the silence detection operation in step 11 are suspended until the on-hook is detected in step 12. This prevents switching to facsimile reception during a call. Even if the stop button is not pressed, if the reception mode is not the absence mode (step 8), steps 9, 10, and 11 are similarly suspended until the on-hook is detected in step 12.

In this embodiment, the stop button of the operating means 14 is used to instruct the interruption of the detection of the facsimile start signal, but a dial signal of the telephone set may be used for this purpose. In this case, the monitor circuit is used. Through 5, the interruption signal is detected by the remote signal detecting means 8.

Although the operating means 14 is directly connected to the control means 16 in this embodiment, the operating means may be on a cordless telephone handset in a facsimile apparatus having a cordless telephone function.
