[Industrial applications]
The present invention, before connecting the to the communicating party in response to the call signal relates to receivable facsimile equipment telephone number information of the communication partner.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a facsimile apparatus having a plurality of incoming call modes, a facsimile apparatus having an answering machine TEL direct connection mode, a fax / tel automatic switching mode, an automatic incoming call mode, and a manual incoming call mode has been proposed.
[0003]
In such a facsimile machine, in the automatic incoming call mode, when a call signal is detected, the mode always shifts to facsimile reception, and in the manual incoming call mode, the bell of the telephone is sounded until the telephone is off-hook. I have. Further, in the case of the answering machine TEL direct connection mode, after detecting the closing of the DC loop of the answering machine, a CNG signal or silence is detected for a predetermined time, and when either of them is detected, the process shifts to facsimile reception.
[0004]
In the FAX / TEL automatic switching mode, a CNG signal or silence is detected for a predetermined period of time after an incoming call. If either of them is detected, the process proceeds to facsimile reception. I was doing.
[0005]
[Problems to be solved by the invention]
However, in the above conventional example, when the answering mode is the answering machine TEL direct connection mode, when a voice message is sent from the answering machine, the CNG signal sent from the other party cannot be detected, and the other party wants to communicate. However, there was a drawback that communication was not possible. In addition, there is a disadvantage that the voice of the other party is mistaken for CNG, and a call cannot be made.
[0006]
Further, in the case where the incoming call mode is the FAX / TEL automatic switching mode, when the other party is in manual transmission, if the operator does not immediately start transmission, there is a disadvantage that silence cannot be detected and communication cannot be performed.
[0007]
Further, when the incoming call mode is the automatic incoming call mode, there is a drawback that only the automatic incoming call is always made and the call cannot be made even if the other party wants the call.
[0008]
Further, when the incoming call mode is the manual incoming call mode, there is a drawback that only a bell sound is emitted from the telephone at all times, and communication cannot be performed if there is no person on the receiving side even if the other party wants communication.
[0009]
In view of the above, the applicant of the present application can solve the above-described inconvenience in each of the incoming modes and flexibly respond to the patent application (Japanese Patent Application No. 6-60,151) filed on March 4, 1994. We proposed a facsimile machine as much as possible.
[0010]
This facsimile apparatus has means for storing whether a calling terminal is a call terminal or a communication terminal in accordance with telephone number information, and has an answering machine TEL direct connection mode, a fax / TEL It has an automatic switching mode, an automatic incoming call mode, and a manual incoming call mode.
[0011]
When the mode of the receiving side is the answering machine TEL direct connection mode, when a calling signal is detected, first, a non-ringing incoming call is made and the telephone number information transmitted during the calling signal is checked. If it is a communication terminal, it shifts to facsimile reception. If the calling side is not a communication terminal, it outputs a calling signal to the answering machine TEL direct connection terminal. In addition, if the calling side is not sure whether it is a communication terminal or a call terminal, after DC closing of the answering machine, a predetermined time, a CNG signal, a V21 flag signal, and silence are checked, and when one of these is detected, The process shifts to facsimile reception, and if neither of these is detected, the process does not shift to facsimile reception.
[0012]
If the absence of TEL or facsimile reception is surely detected, the type of the communication terminal or the communication terminal is stored in correspondence with the telephone number information transmitted during the call signal.
[0013]
As a result, in the answering machine TEL direct connection mode, the telephone number information between the calling signals is detected, and if the calling side is a communication terminal, facsimile reception is performed without activating the answering machine TEL (of course, without recording the answering machine). It becomes possible to move to. Further, if the calling side is a call terminal, after the answering machine is DC-closed, the CNG signal, V21 flag, and silence are detected to prevent a shift to facsimile reception due to erroneous detection, and an easy-to-use device can be provided. .
[0014]
Next, in the case where the incoming call mode is the FAX / TEL automatic switching mode, first, a non-ringing incoming call is made and the telephone number information transmitted during the call signal is checked. Shift to facsimile reception without ringing as it is, if the calling side is a call terminal, output a call signal to the terminal of the telephone, and if it is not known whether the calling side is a communication terminal or a call terminal, switch to the facsimile communication unit once After capturing the line, the CNG signal, the V21 flag signal, and silence are checked for a predetermined period of time, and if one of them is detected, the process proceeds to facsimile reception. If none of these are detected, the process proceeds to facsimile reception. Do not call the operator.
[0015]
If it is determined that the reception is facsimile reception or telephone call, the type of the communication terminal or the communication terminal is stored in correspondence with the telephone number information transmitted during the call signal.
[0016]
As a result, in the FAX / TEL automatic switching mode, the telephone number information between the call signals is detected, and if the calling side is a communication terminal, facsimile reception without ringing becomes possible. Can also be shifted to the communication mode, and an easy-to-use device can be provided.
[0017]
Next, if the incoming call mode is the automatic incoming call mode, a non-ringing call is made, the telephone number information transmitted during the calling signal is checked, and if the calling side is a calling terminal, a calling signal is sent to the terminal of the telephone. Output. Otherwise, it performs automatic call reception and executes control for facsimile reception. When facsimile reception is actually performed, communication with the communication terminal corresponding to the telephone number information transmitted during this call signal is performed. Remember. As a result, even in the automatic incoming call mode, if the other party wants a call, the call can be made and a convenient device can be provided.
[0018]
Next, when the incoming call mode is the manual incoming call mode, a telephone call signal is output to the terminal of the telephone, and the telephone number information transmitted during the call signal is checked. If the calling side is a communication terminal, facsimile reception is performed. Move to. Thereby, even in the manual incoming call mode, when the other party wants communication, communication becomes possible, and a convenient device can be provided.
[0019]
However, the above application does not particularly refer to the case where the telephone number transmitted during the call signal is registered in both the communication terminal and the telephone terminal.
[0020]
Further, in the case where the telephone number is not transmitted during the call signal, or even if the telephone number is transmitted but is not registered in either the call terminal or the communication terminal, all the communication modes only follow the reception mode, and the communication is performed according to the user's preference. Cannot be denied.
[0021]
In addition, there is no mention of a case where the telephone number between the call signals does not match the telephone number that can be identified by the TSI signal.
[0022]
Further, it was not possible to select which information of the telephone number between the calling signals or the information of the TSI signal should be left in the communication result report.
[0023]
Accordingly, the present invention is to improve the above prior invention, further an object to provide a good facsimile equipment convenient.

Then, in S100, the automatic answering machine 1 performs an answering machine. In S102, it is determined whether or not the timer T1 has timed out. If the timer T1 has timed out, the process proceeds to S104, and if the timer T1 has not timed out. Proceed to S106.
[0088]
In S104, the information on the signal line 4c is input, and it is determined whether or not the external answering machine 1 has opened the DC loop, that is, whether or not the answering machine has been completed. If the recording has not been completed, the process proceeds to S100.
[0089]
In S106, information of the signal lines 34a, 36a, and 37a is input, and it is determined whether a CNG signal, a flag signal of a V21 signal, or silence has been detected, and if any one is detected, the process proceeds to S108. Then, the process proceeds to facsimile reception, and if none is detected, the process proceeds to S104.
[0090]
In S108, a signal of signal level "1" is output to the signal line 48a to turn on the CML, and in S110, facsimile reception is performed.
[0091]
Next, in S112, the signal of the signal level "0" is output to the signal line 48a to turn off the CML. In S114, it is determined whether or not the facsimile reception is successful. Since it can be determined that the terminal is a communication terminal, the process proceeds to S116. If the telephone number between the call signals is detected, the telephone number is registered in the registration circuit 42. If the facsimile reception has not been successful, the process proceeds to S54 and returns to the initial state.
[0092]
In S118, it is determined whether or not the answering machine was actually performed, for example, whether or not the answering machine was in the answering machine state for a predetermined time or more. If the answering machine was actually performed, the other party can be reliably determined to be the call terminal. Therefore, the process proceeds to S120, where the telephone number between the call signals is detected, the telephone number is registered in the registration circuit 44, and when the answering machine is not recorded, the process proceeds to S54 to return to the initial state.
