Abstract

PURPOSE:To automatically execute voice communication and data communication by providing a selecting means to select a data communication means or a voice communication means in response to the detection of a call signal by a detection means, and a means to set the priority order of the said selection. CONSTITUTION:A CPU 1 discriminates whether a slide switch 21 is in an automatic reception side or not, and if YES, forms the closed loop of a line 17. If the telephone is hooked off, call signals Ci cease, and the titled equipment starts the communication as an ordinary telephone set. In case a password number is set to '00', the function for a message is not operated, and the sequence shifts to facsimile reception mode thereafter. Even if the automatic reception mode is set, since a voice from the opposite can be monitored, an operator can speak by stopping the automatic voice response before the shifting to the facsimile reception mode. Also, if the titled equipment is set in the facsimile automatic reception mode, the sequence immediately shifts to the facsimile reception mode.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a communication device that performs voice and data communication.

[Conventional example]

Traditionally, devices of this type, such as facsimile machines, are connected to a telephone line in one place with a telephone set. The telephone and facsimile machines are then selectively connected to the telephone line by a switching relay.

Normally, the telephone line is connected to the telephone side, but if the facsimile machine is set to automatic reception mode, the line is automatically connected from the telephone side to the facsimile machine side in response to a call signal from the line.

For this reason, if the facsimile machine is set to automatic reception mode, you will not be able to use the telephone, and if the facsimile machine is set to manual reception mode, you will not be able to receive faxes when the operator is not present. Ta.

Additionally, there are multi-function telephones that automatically respond with voice responses, but there is a problem in that when these multi-function telephones and facsimile devices are connected to one telephone line, they cannot be used effectively by simply switching. .

Next, this embodiment will be described in detail with reference to flowcharts showing control operations of the CPUI shown in FIGS. 3 to 10.

A program for performing the following operations is stored in the ROM2. First, when the machine receives a call, it is determined in step Sl whether there is a ringing signal (hereinafter referred to as C4) for 6 seconds, and if there is no C4 for 6 consecutive seconds, it is turned OFF.
When Ci is detected continuously for 6 seconds, the process advances to step S2. In addition, in the Ci detection in this embodiment, the CPU determines whether or not the line control unit has detected a calling signal (Ci).
This is done by determining I. Step S2 is the second
It is determined whether or not the slide switch 21 in the figure is set to automatic reception. If automatic reception is not automatic reception, the process proceeds to step S3. If automatic reception is automatic reception, a closed loop is formed on the line 17 (line capture) and the process proceeds to step S5. In step S3, it is determined whether the slide switch 21 in FIG. 2 is set to manual reception, and if manual reception is selected, the telephone operates as a normal telephone and rings a bell to call an operator.

Further, if the slide switch 21 is set to automatic reception, the process proceeds from step S2 to step S5, and if the slide switch 21 is set to tamper prevention, the process proceeds from step S3 to step S4. In step S4, it is determined whether Ci is detected for 9 seconds following step S1 (total 15 seconds), and if Ci is not detected for 9 seconds, it is turned OFF.
When Ci is detected for 9 seconds, a closed loop of the line 17 is formed (line capture), and the process proceeds to step S5. Furthermore, if the handset is picked up between steps S1 and S4, Ci is disconnected and the call can be made using a normal telephone without proceeding to the following steps.

If the PIN number is set to "00n" in step S5, the message function (automatic voice response) is not executed and the process advances to step S81 to proceed to facsimile reception; if the PIN number is other than "00", step In S6, it is determined whether a voice message is recorded (stored) in Chl (one phrase of a plurality of voice data areas of DRAM 8), and if a voice message is recorded, 0.
After waiting 5 seconds and reproducing and transmitting the voice message data of Chl in step S7, the process advances to step 58-1 and the C
If no voice message is stored in hi, the process waits for 0.5 seconds in step S8 and then proceeds to step 58-1. The Chl voice message here can be set freely by the operator (the green color is difficult to hear if the voice is sent out at the same time as the line is connected, and the line is unstable immediately after a closed loop is formed). In order to avoid audio transmission, a 0.5 second wait is performed in step S8.

In step 58-1, a voice message (a voice message indicating that it has a facsimile function, for example, "
(e.g. "I have a facsimile function") and sends it to line 17. This allows the other party to be informed that the recipient has a facsimile function.

When the process proceeds from step 58-1 to step S9, a sound, for example a beep sound, is sent to prompt the other party to send a tone dial signal, and then, in step SIO, a tone dial signal is detected from the other party called D-T-M-F detection. , M, and F, and by executing the T, M, and F detection routines, predetermined flags for selecting various modes of the device in which the PIN number is configured from the other party are set. Set.

When a predetermined flag is set, the subroutine is exited and the process proceeds to step Sll. In step Sll, it is determined whether or not the PIN flag set when the PIN from the other party is correct in step SIO is 1. If the PIN flag is -1, the process goes to step 514 (Figure 4), and if not, the process goes to step S12. move on. In step S12,
Check whether the *** flag set when the other party presses the "*" key provided on a normal dial key three times in a row and presses ***=1, and if it is l, step 532. Proceed to (Figure 5).

Further, in step S13, it is checked whether the other party has made a mistake, and the facsimile procedure signal is received from the other party for a predetermined period of time, and if the procedure signal is not received within the predetermined time, it is turned off.

When the process proceeds from step Sll to step S14, it is determined in step S14 whether or not a voice message is stored in Ch2 of the non-volatile RAM 4. If a voice message is stored, the voice message in Ch2 is played back, the line is called, and the voice message is If not stored, a 0.5 second wait is inserted in step S15 as in step S8. In step S17, a beep sound is sent out to prompt the sending of signals T, M, and F, and in step S18, a subroutine D, T, and F is detected on the other side.
Proceed to M and F. In step S19, step S1
At step 8, the ** flag indicating that ** has been detected when the operator on the other side presses the "*" key twice in succession is determined, and if this flag is 1, the process proceeds to step 524 (Figure 6), *
*If the flag is not 1, a misoperation flag indicating whether or not it is a misoperation is determined in step S20. If the misoperation flag is 1, the line is disconnected, and if the misoperation flag is not 1, the process advances to step S21. In step S21, it is determined whether or not the voice message on Ch2 has been reproduced three times. If the voice message on Ch2 has been reproduced three times, the line is released, and if the voice message on Ch2 has not been reproduced three times, the process advances to step S22. In step S22, it is determined again whether a voice message is stored in Ch2, and if Ch2 is empty, the line is released, and if a voice message is stored in Ch2, the voice message in Ch2 is played back, and the process returns to step S17 again. .

On the other hand, if it is determined in step S19 that the ** flag = 1 and the process proceeds to step 524 (FIG. 6), a sound prompting the start of recording, for example, a po sound, is sent out in step S24, and a voice message from the line 17 ( or a voice message from a microphone installed in the device) is recorded on Ch2. Then, in step S25, a predetermined period of time (for example, 8
When the recording of the voice message (seconds to 16 seconds) is completed, a beep sound indicating the end of recording is sent in step S26, Ch2 is automatically played back to confirm the recorded content in step S27, and the other party is notified in step S28. and sends out a beep that prompts T, M, and F. In step S29, it is determined whether or not the recording operation has been performed on Ch2 three times. If it has been three times, the line is released, and if it is less than three times, D, T,
A routine for detecting M and F is entered. Then, in step S31, it is shown that ** has been detected. **The flag is determined, and if it is 1, the process returns to step S24, and if it is not 1, the line is disconnected. This allows the operator on the other side to
” key twice in succession, you can re-record up to three times in total.

On the other hand, if it is determined in step S12 that the *** flag is 1 and the process proceeds to step 532 (FIG. 5), a pop sound indicating the start of recording is sent out in step S32. and step S
At step 33, a voice message from the line 17 or from a microphone provided in the device is recorded to Chi.

Then, in step S34, a beep sound indicating the end of recording is sent out, and in step S35, Chi is automatically played back to confirm the recorded voice message, and in step S36, T, M
, Sends a beep sound to prompt F sending. Next step S37
Determine whether the recording operation to Chi has been performed three times,
If the recording operation is performed three times, the line is released, and if it is less than three times, the process advances to step 538. The DTMF detection routine is executed to detect T, M, and F sent from the other party. Then, in step S39, the "*" key is pressed three times in a row again **
Determine the *** flag indicating that * has been detected, and
＊＊＊＊＊＊If the lag is 1, the process returns to step S32; otherwise, the line is disconnected. This allows the operator at the other end to re-record up to three times by pressing the "*" key three times in succession. Next, D, T,
The T, M, and F detection subroutine used to detect M and F will be explained using FIG.

Here, it is assumed that the low re-dip switch for entering the password is set to "11".

In step S40, the CPU sets a 5-second timer of the soft timer 1. D and T shown in Figure 1
, M.

The F detection unit 9 detects T, M, and F from the other party, and in step S41, it is determined whether the DTMF signal indicates 1 (whether the tone dial signal is a tone signal indicating 7 or not). If it is a tone signal, the process advances to step S47;
Otherwise, the process proceeds to step 342. Next step S42
Then, it is determined whether the tone dial signal * of the "*" key has been sent, and if *, the process proceeds to step S47; otherwise, the process proceeds to step S43; Or, it is determined whether a key other than the "*" key, T, M, or F was sent. If a tone signal other than 1 or * is detected in step S43, the process proceeds to step S46, where the misoperation flag is set to 1, and the process proceeds to step S47, where the 5 second timer is set again and no tone dial signal is sent. If the 5 second timer does not come, it is determined in step S44 whether the 5 second timer is over, and if it is over, the time over flag is set to 1 in step S45, and the PETV
PN. If the time has not exceeded in step S44, the process proceeds to step 544-1, where it is determined whether a calling tone signal (CNG) indicating that the other party desires facsimile transmission has been received. This facsimile procedure signal such as the CNG signal is detected by the modem section 18 via the NCU 16.

If CNG has been received in step 544-1, the process advances to step S83 in FIG. 1; if CNG has not been received, the process returns to step S41.

Also, in step S47, a 5 second timer is set, and in step S47, a 5 second timer is set.
48, it is determined whether the misoperation flag=1 in step 348, and if it is 1, the process proceeds to step S.
If the error operation flag is not 1, then in step S49, it is determined whether 1 was sent after 1, that is, whether 11 was sent.
If so, the process advances to step S55 and the 5 second timer is set again. If it is other than 11, step 49 to step 50
Proceeding to step S50, it is determined whether ** has been sent.
** If so, go to step S55 Otherwise, step S51
Proceed to.

In step S51, it is determined whether a value other than 11 or ** is detected. If a value other than 11 or ** is detected, a misoperation flag is set in step S54, and the process proceeds to step S55. In step S52, the second digit number is
If T, M, and F cannot be detected and the 5-second timer exceeds, a time-over flag is set in step S53 and the process returns. Also, if the time has not exceeded in step S52, the process advances to step 552-1, and step 5
44-1, determine whether CNG is received or not,
If CNG is received, the process advances to step S83, and if CNG is not received, the process returns to step S348. In step S55, the 5 second timer is reset and step 856 (eighth
If the misoperation flag is 1 in step S56, the process proceeds to step S59; otherwise, the process proceeds to step S57. If it is determined in step S57 that the tone signal of the # key is detected after the 11 detection, a password flag indicating that the password has been confirmed is set in step S63, and the process returns.

Also, if it is other than 11# in step S57, step S58
In step S58, it is determined whether * after **detection has been detected, that is, three consecutive *** has been detected, and if *** is detected, the *** flag is set to 1 in step S64. RETURN If it is other than L or ***, it is determined in step S59 whether 11# or other than *** is detected, and if detected, the misoperation flag is set to 1 in step S62 and RETURN is performed. If the third digit cannot be detected, it is determined in step S60 whether the 5 second timer is over, and if it is over, the time over flag is set to 1 in step S61, and if only two consecutive ** are detected at this time. After setting the flag to 1, RETVRN L is reached, and if the time is not over, the process proceeds to step 560-1. Then, in step 560-1, similarly to step 544-1, if there is CNG reception, the process advances to step S82, and if there is no CNG reception, the process returns to step S56.

On the other hand, when the process proceeds from step S5 to step S8 in order to receive a facsimile, it is indicated in step S81 that it is a non-voice terminal (indicates that it is sending a facsimile).
The called station identification signal (CED) is sent to the line 17 via the modem section 18, line control section 10 and SNCU 16, and the process advances to step S83. Then, in step 383, the digital identification signal (DI
S), and in step S84, the other party sends D
A training check to detect whether a digital command signal (DCS) has been received to determine the mode of facsimile communication based on IS, set the facsimile mode of the detected DOS, and check communication in the DCS setting mode. It is detected whether a signal (TCP signal) has been received, and when the reception of DCS and TCP is completed, the process advances to step S85. Note that if there is no signal for a predetermined period of time in step S84, or if the reception of DCS and TCP is not completed within a predetermined period of time, the line will be released as an error and the process will end (error termination).

When the reception of DCS and TCP is completed in step S84 and the process proceeds to step S85, a reception preparation confirmation signal (CFR signal) indicating that preparations for reception are completed is sent, and then step S8
6. In S87, it is determined whether an image signal or a procedure signal of the facsimile communication procedure (in this case, EOP indicating the end of the procedure, EOM indicating the end of the message, MPS indicating the presence of the next page, etc.) is received. If it is determined in step S86 that an image signal has been received, the received image signal is demodulated in the modem unit 18 in step S88, decoded, and output as binary image data to the recording unit 6 for recording. When the image signal of one page is received and recorded in this way, the procedure signal of the facsimile communication procedure is received and detected in step S87, and step S89
゜S91. S93. A procedure signal is determined in S99, and if it is determined in step S89 that a multi-page signal (MPS) has been received, a message confirmation signal (
After sending out the MCF signal, the process returns to step S86.
Receive and record the image signal for the next page. Step S91
If it is determined that the message end signal (ROM) has been received, the MCF signal is sent in step S92, and then the process proceeds to step S8.
Returning to step 3, perform the pre-procedure of the facsimile communication procedure.

If it is determined in step 393 that the procedure end signal (EOP) has been received, the MCF signal is sent in step S94, and the line disconnection signal (IcN signal) is detected within a predetermined time in step S95, and the DCN signal is sent within a predetermined time. If detected, the line 17 is opened in step S96 and the process proceeds to step S97.

If it is determined in step S99 that a call request signal has been received, the operator is called by the speaker 5, and the mode shifts to the call mode.

When the process proceeds to step S97, it is determined whether or not the facsimile reception has been performed following the recording of the voice message on Ch2, and if it is determined that the facsimile reception recording has been performed following the voice message recording, step S98
Then, image data such as "voice message present" stored in the non-volatile RAM 4 is read out and printed out at the end of the recording paper on which the received image is recorded. As a result, the operator at the other end can send the image by facsimile after recording a voice message regarding the image data to be transmitted in the DRAM 8, so that the voice message can be added to the image, and the recording paper on which the image is recorded can be used to record the voice message. Since information indicating that there is a message is additionally recorded, the operator on the receiving side can easily know that there is a voice message in the received image.

Note that step 8 may be performed using the built-in speaker of this unit.
Since the signals from the lines from 1 to SIO are output as sound, it is possible to monitor the voice from the other party without taking the receiver off-hook.

As a result, when a person who does not understand the specifications of this unit calls from outside the unit, the user can monitor the voice and, if there is a person near the unit, pick up the handset 11 shown in Figure 1. By pressing the stop button shown on the keyboard in FIG. 2 and canceling the message function midway through, you can talk to the other party in the same way as with a normal phone call.

Next, the case where this device is used to record data from a microphone and reproduce it from a speaker will be explained using FIG. 9.

In step S65, it is determined whether the password is set to "00", and if it is "OO", it is turned off. If it is other than "00", it is determined in step S66 whether the message key 22 shown on the keyboard in FIG. 2 has been pressed, and if it has been pressed, the process advances to step S67; if it has not been pressed, the process advances to step S72. In step S67, it is determined whether the hold key 23 is pressed, that is, whether the message key 22 and the hold key 23 are pressed at the same time. If it is not pressed, proceed to OFF. In step S73, it is determined whether or not the message key 22 has been pressed, that is, in step S73.
Similarly to step 67, it is determined whether or not the hold key 23 and message key 22 have been pressed at the same time. If they have been pressed, the process advances to step 368; if not, the process advances to hold.

In step 568, the user is prompted to start recording. In step S69, the keyboard slide switch 24 of the keyboard shown in FIG. Execute recording. In step S71, a beep is sent out to notify the end of recording, and the device is turned off.

Switch 24 determines whether standard is fine. If standard, proceed to step S79; if fine, proceed to step S76. In step S79, it is determined whether or not Ch2 has content, and if it is empty, the process advances to step S78.

If there is content, Ch2 is reproduced in step S80, and the process advances to step S78. If it is standard, in step S76,
Determine whether or not Chi has content, and if it is empty, go to step S78; if there is content, play Chi in step S77 and go to step 378; here, play/end or if Chi or Ch2 is empty, it is empty. It sends out a beep sound indicating this and proceeds to OFF.

As described above, in this embodiment, automatic voice response and automatic facsimile reception can be performed by setting automatic reception. At this time, if the automatic voice response mode is selected, the voice message recorded in Chl of DRAM 8 will be sent out, but even in the automatic voice response mode, when a facsimile reception signal is received after sending the voice message, the facsimile will be sent automatically. Can receive data. Furthermore, since the voice from the other party can be monitored even when the automatic reception mode is set, the operator can make a call by stopping the automatic voice response before proceeding to facsimile reception.

Also, set the machine to automatic facsimile reception mode (it will immediately switch to facsimile reception).

That is, in this embodiment, it is possible to set whether voice communication is given priority or facsimile communication is given priority.

By selecting the automatic voice response mode, the device can be used primarily for telephone calls, and can also automatically receive facsimiles.

Furthermore, if the automatic voice response mode is set, it will take time to receive a facsimile, so if the device is mainly used for facsimile communications, it may be set to the automatic facsimile reception mode.

In addition, in this embodiment, the voice message C at the time of voice response
You can freely rewrite hi's voice message from your phone while you are away by entering your PIN using a tone dial signal, so for example, you can change a voice message that says, "I'm currently going to XX." to "I'm currently going to XX." It can be rewritten into a voice message saying,

In addition, in this embodiment, when transmitting a sound signal to the other party, it is avoided immediately after the line is captured, and is sent after a predetermined period of time after the line is captured, so that the operator on the other party hears the sound signal without fail. I can do it.

Furthermore, in this embodiment, when a voice message is recorded from outside, the recorded message is automatically played back, so it is possible to easily check whether the voice message has been recorded reliably. You can re-record a voice message up to three times.

Although the present embodiment has been described using a telephone-integrated facsimile device as an example, the present invention is not limited to the facsimile machine, and may be a data communication device such as a teletex, and is not limited to the telephone-integrated type.
