Abstract

PURPOSE:To exactly transmit sound information to the opposite by blocking the transmission of sound information for a prescribed time immediately after forming a closed loop by a loop forming means. CONSTITUTION:If a telephone call comes in the titled equipment, whether or not ringing signals Ci lasts for 6 sec or not is discriminated, and if the Ci is detected continuously for 6 sec, the closed loop of a line 17 is formed. If a voice message is stored in one Ch 1 of the plural voice data areas of a DRAM 8, the said voice message is reproduced and transmitted after waiting for 0.5 sec. If the voice information is not stored in the Ch 1, a voice message stored in the special area of a ROM 2 or the DRAM 8 is is reproduced and transmitted to the line 17 after waiting for 0.5 sec with a step 8. Likewise, to transmit a sound signal to the opposite, the transmission is achieved after waiting for the prescribed time after the line is captured. As a result an operator on the opposite side can hear the sound signal exactly.

Next, this embodiment will be described in detail with reference to flowcharts showing the clouding operation of the CPU 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 Ci) for 6 seconds, and if there is no Ci for 6 consecutive seconds, 0FFL is sent.
, when Ci is detected continuously for 6 seconds, the process advances to step S2. Incidentally, Ci detection in this embodiment is performed by the CPUI determining whether or not the line control section detects a calling signal (Ci). In step S2, it is determined whether the slide switch 21 in FIG. move on. 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 C4 is detected for 9 seconds (total 15 seconds) following step S1, and if C4 is not detected for 9 seconds, 0FF is set.
When L and Ci are 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 "00" in step S5, the message function (automatic voice response) is not executed and the process proceeds to step S81 to proceed to facsimile reception; if the PIN number is other than "00", In step S6, it is determined whether a voice message is recorded (stored) in Chi (one of the plurality of voice data areas of DRAM8), and if a voice message is recorded, step 56-1 is performed. 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. Chi's voice message here can be set freely by the operator (the green color means that if you send out the voice at the same time as the line is connected, it will be easier to hear ((, also, the line is unstable immediately after the closed loop is formed). In order to avoid the audio transmission, a 0.5 second wait is performed in step S8.

In step 58-1, ROM 2 or DRAM 8
The voice message (voice message indicating that it has a facsimile function, for example, "Facsimile function is available") stored in the time-determined area of the line 1 is played back.
Send on 7. This allows you to notify the other party that you have a refax 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 this D, T, M, and F detection routine, 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. Step Sl
In step S10, it is determined whether the PIN flag set when the other party's PIN is correct is 1, and if the PIN flag is 1, the process goes to step 514 (Figure 4); if not, the process goes to step S12. . Step S12
In this case, check whether the *** flag that is set when the other party presses the ``*'' key on a normal dial key three times in a row and presses the *** flag = 1.
If so, the process advances to step 532 (FIG. 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 advances 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 to prompt the transmission of T, M, and F, and in step S]8, the subroutine D, T, M, and F is detected to detect the other party's beams, T, M, and F.
Proceed to. In step S19, in step S18, the ** flag indicating that ** is detected when the operator on the other side presses the "*" key twice in succession is determined, and this flag is determined to be 1.
If so, proceed to step 524 (Figure 6), and the ** flag is set to 1.
If not, a misoperation flag indicating whether 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 C)]2, 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 step is repeated. Return to S17.

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 out in step S26, Ch2 is automatically played back to confirm the recorded content in step S27, and the other party is notified in step 328. D, T, M
, Sends out a beep that prompts F. Ch in step S29
2, it is determined whether or not the recording operation has been performed three times, and if the recording operation has been performed three times, the line is released, and if it is less than three times, the process goes to step S30,
A routine for detecting T, 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 Chl.

Then, in step S34, a beep sound indicating the end of recording is sent out, and in step S35, Chl 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, proceed to step 33B. Executes the DTMF detection routine and detects Ruri, 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 flag=11, 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 or - three times in succession. Next, the T, M, and F detection subroutine used for detecting T, M, and F will be explained using FIG.

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

In step S40, a 5 second timer of the software timer of the CPU 1 is set. As shown in FIG. 1, T and 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 advances to step S42. 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; *" It is determined whether a key other than the key, T, M, or F has been 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 84.7, where the tone signal is 5 again.
A second timer is set, and if no tone dial signal is sent, 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 PET
VPN. 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 is -1 in step S48, and if ■, step S
If the error operation flag is not 1, it is determined in step S49 whether 1 was sent after ■, 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 or not something other than 11 or *; is detected. If something other than 11 or ** is detected, a misoperation flag is set in step S54, and the process proceeds to step S55. In step S52, if the 5-second timer exceeds because the second digit T, M, and F cannot be detected, a time over flag is set in step S53 and the process returns. If it is determined in step S52 that the time has not exceeded, the process proceeds to step 552-1, in which it is determined whether or not CNG has been received, in the same manner as step 544-1. If CNG is received, the process proceeds to step S83, in which the CNG
If not received, the process returns to step S48. Step S5
5, reset the 5 second timer and proceed to step 856 (
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 1, 1# in step S57, step S5
8, and in step 358, **after detection* is 3.
Determine whether or not consecutive *** times are detected, and
If it is detected, the *** flag is set to 1 in step S64, and RETURN L is sent. Set the misoperation flag to 1 and return. 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. If, after setting the flag to 1, RETVRN t, the time has not exceeded, the process proceeds to step 560-1. Then, in step S60-1, CN
If there is G 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 modem section 18, line control section 10. It is sent to the line 17 via the NCU 16 and the process advances to step S83. Then, in step S83, the digital identification signal (DI
S), and in step S84, the other party sends DT
A training check to detect whether a digital command signal (DO3) has been received to determine the mode of facsimile communication based on S, set the facsimile mode of the detected DO3, and check communication in the setting mode of DC8. It is detected whether a signal (TCP signal) has been received, and when the reception of DC3 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 DC3STCF 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 DC8 and TCF 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 a multi-page signal (MPS) is determined in step S89.
If it is determined that the message has been received, a message confirmation signal (MCF signal) is sent in step S90, and then the process returns to step S86 to receive and record the image signal of the next page. Step S
If it is determined in step 91 that an end-of-message signal (EOM) has been received, the MCF signal is sent in step S92, and then the process returns to step S83 to perform the pre-facsimile communication procedure.

Further, if it is determined in step S93 that the procedure end signal (EOP) has been received, the MCF signal is sent in step S94, and then,
If a line disconnection signal (%CN signal) is received and detected within a predetermined time in step S95 and a DCN signal is detected within a predetermined time, the line 17 is released in step S96 and step S97
Proceed to.

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.

Further, when the process proceeds to step S97, it is determined whether the facsimile reception was performed following the recording of the voice message on Ch2, and if it is determined that the facsimile reception recording was 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 the existence of 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 1 to S10 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 voice can be monitored and if the person is near the unit, the handset 11 shown in Figure 1 can be removed. 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 has been set to "00", and if it is "00", 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. 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, and it is determined whether the hold key 23 is pressed. If the hold key 23 is pressed, the process advances to step S73. If not, the process advances to OFF.In step S73, it is determined whether 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 868; if not, the process advances to hold.

In step S68, the user is prompted to start recording. In step S69, the 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 S378.

If there is content, Ch2 is reproduced in step S80, and the process advances to step 878. If it is standard, in step S76,
Determine whether or not Chi has content, and if it is empty, go to step 378; if there is content, play Chi in step S77 and go to step 378; here, playback/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 chi 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 fax 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.

Furthermore, if the facsimile automatic reception mode is set, the machine immediately shifts 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 out 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 “.

Furthermore, 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 at the other party can reliably hear the sound signal ( 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.

〔effect〕

As described above, according to the present invention, sound information can be reliably transmitted to the other party.
