Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication device that performs voice communication via a line.

[Prior Art] Conventionally, after a facsimile machine has finished receiving a message or an answering machine has recorded an answering machine,
A call was made to a registered destination, and then a message was immediately sent out.

[Problem to be solved by the invention] However, in the conventional example described above, if some message is returned from the other party in response to a message from oneself, the message from the other party and the message sent by oneself may collide. The problem was that the message could not be sent correctly to the other party.

For example, when you try to call a display pager and send a message, if you dial the display pager's number on your phone, you will receive a message that says, ``This is your pager.''

Please send me a message,'' an announcement says. Therefore, if you send your own messages while this announcement is being played, there is a drawback that they will collide with each other.

[Means for Solving the Problems] The present invention includes a detection means for detecting voice energy on a line, and detects that the voice energy on the line is in a silent state below a predetermined level by the detection means. By providing a detection means for outputting a predetermined signal to the line when the detection means detects that there is no sound, a predetermined signal can be outputted to the line after the voice output from the other party is finished. It is designed to output a signal.

[Embodiment] This embodiment has a modem with an auto-dial function and an energy detection function. Then, the image information received during automatic reception is received in the memory, and after the reception is completed, a call is automatically made to the pre-registered phone number. Furthermore, after making a call, energy reception is performed, and when the energy runs out for a certain period of time, a DT is sent to the user indicating that a facsimile has been received.
Sends messages such as MF signals. This makes it possible to retrieve the received image information from another facsimile.

FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention.

The CPU (Central Processing Unit) 1 has a read-only memory (
It controls the entire facsimile machine according to the program stored in the ROM) 2, and includes a random access memory (RAM) 3, a non-volatile RAM 4,
Modem section 8, network control unit (NCU) 9, operation section 12
, the display section 13, and the selection signal sending section 14.

The RAM 3 converts the signal modulated by the modem section 8 into an NC
It stores the binarized image data output to the telephone line 10 via U9. Further, the RAM 3 demodulates the analog waveform input manually from the telephone line 10 via the NCU 9 and the modem section 8, and stores the binarized data.

The non-volatile RAM 4 reliably stores data to be saved even when the power to the facsimile machine is cut off. Also, non-volatile RAM4 is operated by #
This is one of the registration means for registering the name of the other party and the telephone number of the other party via the telephone number 12.

Then, based on the program stored in the ROM 2, the CPUI has a function as a transmitting means for transmitting the destination name corresponding to the manually entered destination telephone number to the destination receiver.

The modem section 8 has G3. G2. Gl, FM modem and clock generation circuit connected to these modems Audio/DTMF
It is composed of a detection circuit, etc., and modulates the transmission data stored in the RAM 3 based on the control of the CPUI,
It is output to the telephone line 10 via the NCU 9.

Furthermore, the modem section 8 transmits the analog signal of the telephone line IO to N
The data is introduced via the CU 9, demodulated and binarized, and the data is stored in the RAM 3.

The NCU 9 connects the telephone line to the modem section 8 or telephone device under the control of the CPU t. 1 for connection.

The operation unit 12 includes a key for starting transmission, reception, etc.
It is composed of a remote selection key for specifying an operation mode such as fine, standard, and automatic reception during transmission and reception, and a numeric keypad. Note that the CPU 1 detects the pressed state of these keys and controls each of the above-mentioned parts according to the pressed state.

The selection signal sending unit 14 selects the NCU under the control of cput.
9, a selection signal for a pulse dialer, tone dialer, etc. is sent out.

The audio recording unit 15 records the analog signal of the line through the NCU 9 under the control of cput.

Next, the present embodiment will be explained according to the flowchart shown in FIG.

In this embodiment, facsimile reception will be described.

In SL, manual / T E L F A X on the operation unit 12
If the switch is in manual mode, facsimile reception is performed manually in S2. On the other hand, if it is an in-place fax (telefax mode), the software switch in volatile RAM 4 is determined in S3, and if in-place fax is prohibited (telefax prohibited mode), voice response 1 is sent in S4 (this is connected to the fax machine). ) and performs automatic reception towards 5. Thereafter, in S55 it is determined whether it is a pager call, and if it is a pager call, the call is made to the facsimile pager telephone number registered in advance in 356. Otherwise, just exit.

Also, if incoming faxes are not prohibited, voice response 2 (if you are using fax, please press the start button, if you are calling, please say "moshimoshi". In other words, a response for automatic incoming/outgoing fax switching will be output to the line. S7 .S9.DTMF (Dual Tone Multi Frequency) for each SIO
, CNG (calling tone), voice is detected, and DTM is detected in S7.
If it is F, go to the remote transmission of S8 and receive the DTM.
If F is the first, the content received in memory in S14 is
When the start button of another facsimile is pressed, the contents received in the memory are polled and transmitted. If the second is S
18 IC recorded contents are sent to the other party via a telephone line. When CNG is detected in S9,
The operation unit 12 determines whether the call is a pager call at step l, and if it is not a pager call, the call is automatically received at step S13.

If it is a pager call, the operation unit 12 determines whether memory reception is to be performed in S12. If memory reception is not to be performed, the process proceeds to S5; if memory reception is to be performed, memory reception is performed in S14, and a pager call 2 for FAX is performed in S15.

If the SIO detects a voice, the process goes to 318, and if the stationary pager call switch is on, the voice signal is recorded in the voice recording unit 15 at 318, and the stationary pager call l is performed at S19.

If it is not a pager call, the NCN 9 generates a pseudo Ci to the telephone 11 in S17, and the ringer is activated.

In this embodiment, in this way, the operation unit 12 has manual/TE
We have an L F A X switch, a pager call-on switch for FAX, a pager call switch for stationary use, and a switch to enable/disable memory reception.

The operation when making a pager call will be explained using the flowchart shown in FIG.

When the CPU 1 finishes receiving the facsimile memory or recording the missed message, it explicitly starts a timer in the RAM 4 using the timer area of the RAM 3 (step 5).
31), and the modem unit 8 detects voice energy (step 532). Modem section 8 generates a signal indicating whether the voice energy on telephone line 10 is below a predetermined value. As mentioned above, after calling the display pager, an announcement saying ``This is a pager. Please send a message'' is heard from the telephone line 10. This message is sent within 2 seconds after the call is made.

Therefore, the CPU 1 uses a timer area in the RAM 3 to measure the time while the modem section 8 is generating a signal indicating the silent state. If the message is received via the line 10 within 2 seconds, the timer is reset (step 533).

Then, when the message is finished and it is detected that silence has continued for another 2 seconds (step 534), the CPU uses *400*8 DTMF (Dual Tone Multi Frequency) when the facsimile memory is received.
A signal is output to the telephone line 10 and 00 is displayed on the display pager. Also, when recording an answering message, a DTMF signal of *499*8 is output, and a DTMF signal of 99
Display. This allows the pager user to know whether the received message is a facsimile or a telephone call.

In this way, in this embodiment, after a pager call is made, the energy of the telephone line is detected, and if the silence continues for two seconds, it is determined that the message from the line has ended. After making this determination, by sending a message from this side, this solves the problem of the other side not being able to correctly recognize messages from the other side due to messages being generated on the other side and this side at the same time.

[Other Examples] Here, in all cases, energy detection was performed after automatic call origination, but by allowing the user to change whether or not to detect energy using a switch, it is possible for the other party to It can be used when it is a person rather than a pager. In that case, it is more effective to use a voice message instead of a DTMF signal. That is, the facsimile memory reception/recording of an absentee message may be notified by a voice message.

[Effects of the Invention] As explained above, according to the present invention, when a silent state is detected, a predetermined signal is output to the line, thereby preventing a message from colliding with a message from the line. Can be done. Therefore, there is an effect of allowing the other party to accurately recognize the signal.
