DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus, and more particularly to a home facsimile apparatus in which one line of a telephone is switched and used for communication and facsimile.

[0002]

2. Description of the Related Art In a conventional home facsimile machine, a single telephone line is switched between a telephone and a facsimile machine to be shared, and a facsimile reception is manually and automatically switched by a changeover switch.
A normal telephone call is made at the above-mentioned manual position, and when a facsimile is received at the manual position, a facsimile is received after a conversation such as sending a facsimile is performed first. That is, when the receiving side is at home, the manual position is preferable. On the other hand, when the receiving side is absent, the position is switched to the automatic position and the facsimile is automatically received.

FIG. 5 is a sequence diagram in the automatic reception of the facsimile. First, the receiving side of the facsimile apparatus causes the transmitting side to ring, for example, about six times (RBT,
(Ring Back Tone) 31 is transmitted, and if the receiver is disconnected during this time (OFFHOOK), a normal call is made. Also, if there is no other party during this period, the telephone fee is not charged. If OFFHOOK is not performed within the above period, for example, a message (MSG) 32 such as “Please wait for a while” stored in advance is sent back, and a CNG signal which is a facsimile transmission signal arrives in the next calling period 33. Waits for facsimile reception when this is detected.
A CED signal indicating K is transmitted and facsimile reception starts immediately. Since the MSG 32 and the subsequent stations need to wait for the CNG signal, the telephone line is charged because the line is connected.

If the CED signal does not arrive, the MSG 34 after a predetermined ringing period 33, such as "I am out of the office. Call me again. Send me a fax." Send back
Subsequently, the CED signal 35 is transmitted. The sending side is the above CED
The signal is received and facsimile transmission is started. Also,
During the ringing period 33, RBT until the CED signal arrives
Is transmitted and the call is continued, so that the receiver can be turned OFFHOOK during this time for talking. The number of RBTs issued during the calling period 31 can be changed by a switch.

[0005] Further, a single telephone line is automatically switched between an answering machine and a facsimile machine. In this case, similarly to the above, the facsimile apparatus automatically receives an incoming call and calls the answering machine if the facsimile is not transmitted, and the facsimile machine receives the incoming call first and the facsimile is transmitted. There are two methods: a method in which a telephone line is switched to a device to perform facsimile reception. If the answering machine does not respond because the number of recorded messages on the answering machine is full, the former method stops the transmission of the RBT and then sends out a facsimile reception signal. A receiving signal is transmitted.

[0006]

In the above-mentioned conventional facsimile apparatus, since the line is connected and the call is continued during the calling period 33, if the called party is absent, the calling party cannot perform the call, but the calling party cannot. There was a problem of being charged. Further, since the number of calls in the calling period 31 is set by a combination of a plurality of switches, there is a problem that the operation is complicated.

Further, in the combination of the facsimile apparatus and the answering machine, if the number of recordings of the answering machine is full, the called side immediately sends a CED signal and starts facsimile reception. A strange sound of the CED signal is heard, and there is a problem that a calling person who does not know the situation is surprised. An object of the present invention is to improve the above-mentioned problems, to be friendly to a person who makes a call, to be easy to operate for a user of a facsimile machine, and to adapt to a frequent use of a telephone. Facsimile machine for use

[0008]

In order to solve the above-mentioned problem, a telephone call is performed without responding to a facsimile call for a predetermined period in response to a facsimile call from a calling side, and during this time, the called side If there is no telephone answering (off-hook) is to be notified by voice a message indicating that the facsimile can receive the calling party. further,
Time to go on-hook to caller after above message
The facsimile transmission guidance signal (CED signal) is transmitted with a delay so as to provide a delay .

[0009]

[0010]

The telephone call is made for a predetermined period in response to the facsimile call from the calling side, and if there is no telephone answer (off-hook), the voice message indicates that the user is out of voice .
Notify the calling side that the message and facsimile can be received . After the above message, the calling party turns ONH.
A silence section for OOK is provided, and then a facsimile transmission guidance signal (CED signal) is transmitted to the calling side for C
Prevents ED signal sound from reaching.

[0011]

[0012]

FIG. 1 is a sequence diagram illustrating a method for automatically switching between a telephone and a facsimile apparatus in a facsimile apparatus according to the present invention. In FIG. 1, the dotted line indicates the time when the calling side has completed dialing. In response to the completion of the dialing, the calling side transmits a facsimile calling signal CNG13 or waits for a telephone response of the called side. In the called side, a predetermined ringing period 15
Ring the phone's bell within and continue calling.

The facsimile apparatus of the present invention is provided with a switch for designating a home mode and a non-home mode. Is automatically switched to the facsimile side, a message (MSG) 18 is sent to the calling side, and the fact that he / she is away is reported to give up the call. It should be noted that the called party continues to call while the message 18 is being sent,
If FFHOOK is done, make a call possible.

If the OFFHOOK is not performed until after the end of the MSG 18, the CED signal 19 is kept in a silent state for about 5 seconds.
To receive facsimile. By providing the above-mentioned silence state, the calling side hears an unusual CED signal at the same time as the end of the message 18 and turns on without being surprised.
You can afford to HOOK. In the above-mentioned home mode, since the calling side is not charged if the caller sets ONHOOK within the calling period 15, there is a problem in the conventional apparatus that the called side is charged even if the called party is absent, as in the calling period 33 shown in FIG. Can be eliminated.

Further, since the length of the calling period 15 can be adjusted in advance in accordance with the situation, it is possible to prevent the facsimile from being accepted after the calling party has been insignificantly waited for a long time. Also, the CNG signal transmitted by the calling side is represented by M
It is also possible to detect facsimile reception during the period of SG18 or during the silent period with MSG18. In this case, in order to prevent malfunction of CNG detection due to the sound of MSG1, a filter is used to remove CNG from the sound.
The frequency component of the NG signal is removed, or a voice from which the frequency component of the CNG signal is removed in advance is used.

In the absence mode in FIG. 1, the calling is not required to be made, so the calling period 15 is omitted, and the sequence immediately after the MSG 18 immediately after the incoming call is started. The switching method of the present invention shown in FIG. 1 can be applied to a case where an answering machine is connected to a facsimile. When the number of recorded messages of the answering machine is full, calling is performed a predetermined number of times during the calling period 15, and if there is no response, the MSG 18 is transmitted to notify that the user is in the absence mode, and the CED signal is transmitted through a silent section. Start receiving facsimile. This can prevent the calling side from being surprised by suddenly hearing an abnormal sound of the CED signal after a predetermined number of telephone calls.

Whether the number of recorded voicemails is full or not is determined by the presence or absence of a response from the voicemail within the above-mentioned predetermined number of calling periods. The number of calls can be arbitrarily set by the called party using a switch, and can also be set to a non-ringing incoming call.

FIG. 2 is a block diagram showing a sequence control system in the facsimile apparatus according to the present invention.
21 is a telephone line from the calling side, and 22 is a called line. In the home mode, in the initial state, the telephone line 21 is connected to the telephone side 221 of the CML relay 22,
When there is a call from the telephone office, the RI detection circuit 28 detects a ringing tone, and the CPU 27 monitors the number of ringing sounds, and the called side does not OFFHOOK until the number reaches a predetermined number (for example, 10 times which is initially set). Judging that the CML relay 22 is on the 222 side (the facsimile side)
, And the message 1
8 is output to notify the calling party that he is out of the office.

It should be noted that the above call is continued even while the message 18 is being sent out, and that the RL relay 23
Is switched to the 232 side so that a call can be made. If OFFHOOK is not performed during this time, a silence state is maintained for about 5 seconds, and then a CED signal is transmitted from the modem 25 to receive a facsimile. According to the above sequence, MSG1
Since the charge is made only for the call after 8, it is possible to prevent the inconvenience of being charged after waiting during the call period 15 as in the conventional device.

FIG. 3 is a flow chart of the sequence of the present invention. In step 102, the above-mentioned RI detection is performed. In step 103, it is checked whether or not the mode switch is in the home mode.
At 04, the RL relay 23 is connected to the 232 side.
If HOOK is made, the process moves to step 111 to start a telephone call. If OFFHOOK is not performed here, step 105
Detects that the number of calls has reached 10 times, connects the CML relay 22 to the 222 side in step 106,
In step 107, the MSG 18 is sent to the calling side.

Next, at step 108, it is checked whether or not the OFFHOOK is performed during the transmission of the MSG18.
If OK, CML relay 22 is set to 2 at step 114.
21 and the RL relay 23 is connected to the 232 side to start a call. If OFFHOOK is not performed, it is detected in step 115 that 5 seconds of the silent section has elapsed, and a CED signal is transmitted in step 109 to start facsimile communication in step 110.

FIG. 4 shows an example of a switch used for setting the number of calls counted in step 105.
By moving the slide button, the number of calls can be set, for example, between 0 and 10 with one touch.

[0023]

In the home mode operation of the facsimile apparatus according to the present invention, the telephone call is first made for both the telephone call and the facsimile call.
During this time, the calling party determines that the other party is away and ONHO
If OK, you will not be charged. Further, the facsimile calling side is notified by voice after the above-mentioned calling period and is informed that facsimile reception is possible, so that an unskilled person can transmit a facsimile with ease.

[0024]

Further, since a silent section of about 5 seconds is provided after the voice message and a CED signal is transmitted after that, the calling side suddenly hears the abnormal sound of the CED signal following the voice message. Is prevented. As mentioned above,
Even if the facsimile apparatus is always set to the “home mode” and goes out, there is little annoyance to the calling party, so that the called party can be relieved from the hassle of switching to the “home mode” every time he goes out.
