Abstract

PURPOSE:To prevent facsimile reception from being transited carelessly when an instruction signal for remote reception is detected while an ancillary auto matic answering telephone set replies a call in the select reception setting. CONSTITUTION:The correspondence to a remote signal is switched depending whether reception mode information of a storage means 17 represents the automatic answering mode at that time when a remote signal detection means 9 detects an instruction signal of remote reception while an interface circuit 4 opens a telephone line and off-hook of an ancillary telephone set is detected. That is, in the case of the automatic answering telephone set mode, facsimile reception is implemented only when an ID code is coincident and when no automatic answering telephone set mode is set, the facsimile reception is executed independently of the coincidence of the ID codes. Thus, whether a remote signal is inputted from a caller side or inputted from the ancillary telephone set is judged based on the reception mode information and proper correspondence is attained.

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.

One of them is a remote receiving function. This function sends a simple remote signal (for example, dial "1") from the attached telephone when the attached telephone is off-hook before the facsimile device and it is confirmed that the calling side is a facsimile transmission when there is an incoming call. The function is that the facsimile machine starts communication upon transmission.

Further, recently, unnecessary information such as advertisements is also transmitted by a facsimile machine, and therefore a function of selective reception is added to prevent such information from being received. This function transmits the ID code represented by the DTMF signal and the transmitting station identification signal (TSI) before the transmitting side sends out the image signal, and the facsimile reception is performed only when this ID matches the ID code of the receiving side device. This is the function to perform.

As a combined function of the remote receiving function and the select receiving function, even when the select receiving is set, when the facsimile apparatus is set to the communication mode by the remote receiving, the ID code is not input from the calling side. There is also a function to enable facsimile reception.

[0007]

However, even if the selective reception is set, the facsimile reception can be performed by inputting the remote reception code from the calling side without knowing the selective reception ID code. It had a problem that it could be done.

The present invention has been made in view of the above-mentioned prior art. When the selective reception is set, the remote reception code is issued depending on the hook state of the side telephone and the preset facsimile reception mode. (EN) Provided is a facsimile device capable of performing an appropriate operation by determining whether the input is made from the calling side or the input telephone.

[0009]

In order to achieve this object, a facsimile apparatus of the present invention comprises a storage means for storing the reception mode information instructed by the reception mode instructing means, and the remote signal detecting means stores the remote signal. When the detection is made, the control means is provided for deciding whether or not to compare the ID code with the remote signal based on the reception mode information stored in the storage means.

[0010]

With this configuration, when the remote reception code is detected, the presence or absence of a ring signal before the off-hook of the attached telephone, the closed / open state of the telephone line, and the preset facsimile reception mode are used. Judging whether the code was input from the calling side or from the side-by-side telephone. If it is determined from the calling side, the select reception function is activated. If it is determined from the side-by-side telephone, the ID codes are compared. Instead, the facsimile reception will be performed.

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 a telephone, 3 is 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 3. An interface circuit for closing the telephone line 1 in response to a signal, a monitor circuit for detecting a facsimile communication instruction signal appearing on the telephone line while the off-hook detecting means is detecting the off-hook of the attached telephone, and 6 is a facsimile signal sending means, Reference numeral 7 is a facsimile signal receiving means.

Reference numeral 8 is a CNG signal detecting means, 9 is a remote signal detecting means for detecting a remote signal input from the interface circuit 4 after the interface circuit 4 has closed the telephone line, 10 is a silence detecting means, and 11 is a jack 2. Is an off-hook detecting means for detecting an off-hook of an attached telephone connected to, an image reading means 12 and a printing means 13.

Reference numeral 14 is an operating means, and a receiving mode instruction switch for the user to set the receiving mode is also one of the operating means. Reference numeral 15 is a timer.

Reference numeral 16 is a control means for controlling each part in accordance with each signal, a predetermined procedure (shown in FIG. 2) and a command inputted by the user, and 17 is a storage means. The ID code is stored in this storage means 17.
When the monitor circuit 5 detects a facsimile communication instruction signal, the control means 16 detects the remote signal detection means 9.
When the remote signal detected by is coincident with the ID code stored in the storage means, the facsimile signal receiving means 7 is caused to perform facsimile reception.

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

First, the ID code is set from the operating means 14. For the setting method, set this device to program mode
Enter the code number. This may be one digit or multiple digits. The ID code set in this way is stored in the storage means 17. Next, the select reception mode is set from the operation means 14. If select reception is not set here, the printing operation is performed by the printing unit 13 for all facsimile receptions. When the select reception mode is set, facsimile reception is performed only when the caller sends a remote signal that matches the set ID code.
The printing means 13 prints.

Next, the receiving mode is designated from the operating means 14, and the designated mode is stored in the storing 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.
There are modes that indicate other states.

The incoming operation when the selective reception is set will be described below. First, the ring signal detecting means 3 detects the ring signal input from the telephone line 1,
It is output to the control means 16 (step 1). Control means 16
Detects whether the on-hook telephone is off-hook or not by the off-hook detecting means 11 (step 2). When the ring signal is input a predetermined number of times in advance without detecting the off-hook (step 3), the interface circuit 4 receives the ring signal. The telephone line 1 is closed (step 4).

Next, the operation for detecting the remote signal from the calling party is started (step 5), and the remote signal is transmitted from the calling party, and this is detected by the remote signal detecting means 9 and coincides with the above-mentioned ID code. Then, the facsimile signal receiving operation is started (step 6).

After the telephone line is closed in step 4, timer 1
5 is detected by the remote detecting means 9 within a fixed time measured by
When the remote signal that matches the D code is not detected (step 5) and the off-hook of the attached telephone is not detected by the attached telephone off-hook detection means 11 (step 7), the control means 16 opens the telephone line 1 to the interface circuit 4. (Step 9).

When the off-hook is detected in step 2, the control means 16 monitors the facsimile communication instruction signal input from the telephone set in the monitor circuit 5 (step 10). This state is a call state between the caller and the user of the telephone set, and may be an automatic answering state of the answering machine when an answering machine is connected to the telephone set. 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. The facsimile communication instruction signal may be, for example, a DTMF signal generated by pressing "1" on the dial button.

When the user feels the need for facsimile reception during a telephone call and presses the dial "1" of the telephone attached thereto, this signal is transmitted through the monitor circuit 5 to the remote signal detecting means 9
Is detected by and output to the control means 16.

When the on-hook of the side telephone is detected by the side-phone off-hook detecting means 11 before receiving the facsimile communication instruction signal, the control means 16 stops monitoring the facsimile communication instruction signal (step 11).

When the facsimile communication instruction signal is received and the reception mode instructed in advance by the operation means 14 and stored in the storage means 17 is the absence mode (step 1
2) Close the telephone line (step 4). in this case,
This means that the facsimile instruction signal was received during answering the answering machine, and appropriate measures will be taken when answering the answering machine. That is, in this case, it is determined that the caller has transmitted the facsimile instruction signal, and the remote signal is stored in advance in the I
It is checked whether or not it matches the D code (step 5). By this step 5, the facsimile signal reception (step 6) is performed only when the input remote signal matches the ID code stored in advance.

When the reception mode is not the absence mode, the process directly proceeds from step 12 to step 15, and step 1
At 5 the telephone line 1 is closed to the interface circuit 4, and then a facsimile signal is received (step 6). In this case, it is determined that the user of the side-by-side telephone has sent the facsimile instruction signal because the answering machine is not responding. Therefore, the facsimile signal is received (step 6) without checking the remote signal.

When the off-hook is detected in step 7, the control means 16 causes the interface circuit 4 to open the telephone line 1 (step 13). This state is the same as the off-hook state of the attached telephone in step 2, that is, the call state between the caller and the user of the attached telephone. In this state, the monitor circuit 5 monitors the facsimile communication instruction signal input from the telephone set (step 14). The control means 16 closes the telephone line 1 to the interface circuit 4 by this signal (step 15) and controls the facsimile signal receiving means 7 to start the facsimile signal receiving operation (step 6). In this case, after the telephone line is closed (step 4), it is judged that it is not an automatic answering machine answering machine because it is off-hook in the side telephone with no ring signal, and the remote signal is checked regardless of the reception mode setting. Instead, the facsimile signal is received (step 6).

[0028]

As described above, the present invention is provided with the storage means for storing the reception mode information instructed by the reception mode instruction means, and when the remote signal detection means detects the remote signal, the storage means is stored in the storage means. Since the control means for determining whether to compare the ID code with the remote signal based on the stored reception mode information is provided, when the remote reception code is detected, the ring before the off-hook of the telephone set is installed. Depending on whether or not there is a signal, whether the telephone line is closed or open, and the preset fax reception mode, it is determined whether the code was input from the calling side or the auxiliary telephone, and the calling side If it is judged from the above, the select reception function is activated, and if it is judged from the attached telephone, the facsimile reception is performed without comparing the ID codes. So it is possible, the practical effect is there is a large made.
