Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an answering machine capable of recording messages received from a telephone line onto a recording medium.

[Conventional technology]

With conventional answering machines, messages received are recorded in the order in which they are received, and all messages are treated equally.

[Problem that the invention is trying to solve] However,
In the conventional example described above, when a plurality of messages are recorded, it is not possible to distinguish whether a message is important or not before listening to the recorded message.

[Failure to solve the problem]

According to the present invention, a receiving means for receiving a signal from a line;
(ii) a source analysis means for analyzing source information regarding the source from the signal received from the receiving means; a recording means for recording the signal received from the receiving means on a recording medium; and a recording means for recording the signal on a recording medium by the recording means. By providing a recording start position detection means for detecting the recording start position and an output means for outputting the source information and the recording start position, it is possible to inform the user of the source of the recorded signal and the recording start position. It was designed so that

[First Embodiment] FIG. 1 is a block diagram showing the configuration of a facsimile machine with an answering machine function, which is a first embodiment of the present invention. For voice responses, an RC (semiconductor) memory 3 is used, which is D/A (digital/anahuac) converted and sent to the line. On the other hand, a cassette-type magnetic tape is used to record messages, and audio signals are recorded as analog information.

It has a conversion and transmission function that converts the signal sequence into a signal sequence that can be transmitted in the voice band, such as a signal sequence (ency), and sends it to the line. Then, operate the keys on the operation panel (#3
The control unit 1 activates the conversion and sending function in response to a command signal (specific dial tone) from the other party. Furthermore, the display unit 17 notifies reception of the instruction signal.

Furthermore, in this embodiment, when performing reception, the control unit 1 has a restoring function of restoring the received signal string to the original code string using the same conversion format as that on the transmitting side. Then, the restored code string is divided into a telephone number, an identification code, a code string in the sender's memory, and a key-generated code string.
The data is also stored in the memory]4 as a group of information together with the date and time of reception. The control unit 1 causes the recording unit 11 to output the information group when the number of information groups exceeds a predetermined number or at a predetermined time. Furthermore, the information group that has been output is deleted.

Furthermore, in this embodiment, when receiving a message, it has a function of outputting a signal (specific dial tone) that causes the sender to send out a signal string before or after recording a message from the sender.

Further, in this embodiment, the control unit 1 has a function of storing the coordinate information of the medium on which the message is recorded and the code string received regarding the recording together with the above information group. Further, when the user instructs to delete the coordinate information using the operation unit 13, the control unit 1 deletes the message contents of the corresponding coordinates.

(Detection of Coordinates of Magnetic Tape) The cassette tape drive device 5 is equipped with a rotation amount detector 6 for detecting the amount of tape feed, which detects the current coordinates of the magnetic tape. Access to tape devices is a sequential access method with one-dimensional coordinates, so the coordinates of a magnetic tape are information such as how many seconds have passed since the beginning of tape winding, or how many seconds has passed since the end of winding. . In this embodiment, in order to detect the coordinates of the magnetic tape, a rotation amount detector 6 detects the amount of rotation of the reel of the cassette tape.

A perspective view of the rotation amount detector 6 is shown in FIG. This is a thin opaque disk 3 with a long slit 45 cut in the normal direction.
8 is attached to the reel pobbin 43, and by narrowing this disc 38, a cut-off type photo sensor 39 composed of an LED and a phototransistor is connected. This is a low-resolution encoder fixed to the housing so that it passes through. cassette reel 46
When the reel 46 rotates, the movement is transmitted to the reel holder 43, and the disc 38, which is integrally formed with the reel holder 43, rotates in synchronization with the reel 46.

At this time, since the slit 45 and the non-slit portion of the disk alternately pass on the optical axis of the first F sensor 39, the output waveform of the first F transistor of the cut-off type F first sensor 39 changes to the fourth F first transistor. The result is a rectangular wave as shown in figure (a).

Such a rotation amount detector 6 is installed in the reel hobbin 13 on the delivery side of the cassette tape drive device 5 shown in FIG.

Now, the reproducing mode of this cassette tape drive device is feeding the magnetic tape 48 from the reel 46 to the reel 47 while extracting the magnetically recorded information using the magnetic head 36 as an electric signal. During playback, the feeding speed of the magnetic tape 48 must be kept constant, otherwise signal distortions such as wow and flutter will occur, so in order to stabilize the magnetic tape 48, the capstan roller 35 is directly connected to a flywheel (not shown) and the magnetic tape is connected to the capstan roller 35. There is a pinch roller 34 pressing against 48. These two rollers feed the magnetic tape 48 at a constant speed, while the winding side glue 44 applies a rotational force so that the winding speed is slightly faster than the feeding speed of the magnetic tape. However, since a slip clutch (not shown) is included here, the speed of the magnetic tape is not dependent on the rotational force of the reel bobbin 44.

Further, no rotational force is applied to the reel bobbin 43 on the sending side, but on the contrary, a brake is applied by friction. However, this is not enough to affect the feeding speed of the magnetic tape 48, but is enough to keep the magnetic tape from bending or loosening. Therefore, during playback, the reel bobbin 13
follows the rotation of the reel 46 due to the feed rate of the magnetic tape 48. At this time, since the disk 38 rotates at a substantially constant speed, the optical axis of the blocking photosensor 39 is blocked by the disk 38 or passes through the slit 15. Therefore, the output of the cut-off photosensor 39 is a signal that repeats at approximately constant intervals as shown in FIG. 4(a).

However, when the magnetic tape 48 wound on the reel 46 on the sending side runs out, the end of the magnetic tape is fixed to the reel 46, so even if the capstan roller tries to feed the magnetic tape at a constant speed, the magnetic tape will not move. It doesn't move.

Therefore, the reel 46 does not rotate, and the reel bobbin 43 and disk 38 also do not move, so the output of the cut-off photosensor 39 becomes as shown in FIG. 4(b). The control unit J constantly monitors the output of the photosensor 39, and if the signal does not change within a certain period of time, for example, the time Ts shown in FIG. 4, it determines that the magnetic tape has reached the end and starts driving the tape. stop. The above explanation took the magnetic tape playback mode as an example, but the recording mode is also exactly the same.

Further, in the fast-forward mode, the operation can be further simplified by rotating the reel bobbin 44 and monitoring the output of the photosensor 39 in the same manner as described above with the reel bobbin 13 on the driven side. However, in this case, since the feeding speed of the magnetic tape 48 is not stable, the interval at which the signal changes is also not constant, so it is necessary to allow a sufficient margin for the time Ts used as the criterion.

After the reference address of the end of the magnetic tape is determined in this way, by counting the number of changes in the output of the photosensor 39 of the rotation amount detector 6 with respect to this end, it is possible to determine the end of the magnetic tape at an arbitrary position. Relative coordinates can be uniquely defined.

However, since the resolution of the coordinates in this case depends on the size of the slits 45 cut in the disk 38 and the spacing between the slits, by controlling the magnetic head 36 by the control unit 1, it is possible to record unrecorded areas in the magnetic tape. Coordinates can be determined more accurately by creating a section in which information and counter data are recorded, and detecting it with the magnetic head 36 while fast forwarding.

(Transmission of Digital Data) The control unit 1 centrally controls all of the answering machine function and facsimile function. In the memory 14 of the control unit I, various data and parameters used in the facsimile communication protocol are stored. By the way, your own phone number and identification code for your own machine are provided by CCITT's GM.
Although this is an optional feature that does not require the other party to respond to the Facsimile Pro Col.'s recommendations, most modern facsimile machines have this feature. These are stored in the data area of 14.Specifically, in phase B of the communication protocol, the telephone number is CIG (Calling 5u
The identification code is woven into the other party's communication by a signal called ``bscriber identification'' (calling terminal identification), and the identification code is ``NSC'' (Non-8tanclard F
It exists in a signal named acsimile Command (non-standard function command). Figure 6 shows the phone number C
This is an example in which the data is stored in the memory 14 in accordance with the IG signal format, and each digit is converted into 8-hit numerical information according to the JIS 8 unit code table shown in FIG. Also,
The length is fixed at 20 digits according to the cIG format. Although there is no particular communication format for the identification code, here it is assumed to have a fixed length of 16 digits with a character set based on the JI38 unit code as shown in FIG.

If there is a message other than a telephone number or identification code that makes it easy to understand the intention when sent to the other party, for example, if it is a message, have 8 types of messages #0 to #7 as shown in Figure 8, and send each message. is defined as a 32-digit fixed-length character set based on the JIS8 unit code, which is the same as the identification code. In most cases, fixed forms are sufficient for these messages, so #0 to #4 are predetermined fixed messages, and #5 to #8 are fixed messages that are determined by the user depending on the user's special circumstances. It is a good idea to make this an area where you can input. When in use, any one of #0 to #7 is extracted by key operation on the operating section.

In addition, if -1 facsimile machine is being used by multiple people and you want to identify one of them, please use the 9th facsimile machine.
As shown in the figure, the fixed length of 16 digits is 8 from #O to #7.
The contents are defined in advance by the user from the character set of the JI38 unit code. The user similarly selects any number from #0 to #7 by key operation.

This information is D TMF (D 11 a I

A method of converting the signal into a signal (queency) will be exemplified.

The DTM F signal is used as a dial signal for a telephone, and has three types of high group frequencies (],
]209 I-Iz.

], 336 Hz, 1477 Hz) and four types of low group frequencies (697 Hz.

770 Hz, 852 Hz, 94.1.
Hz) in combination with 3 X +-4, = 1.
Create two types of signals and use them to press the 12 dial keys (1 to 9, *, 0.
#) is assigned. Then, when transmitting a signal, the combined high group frequency and low group frequency are sent out at the same time. The length of the signal is defined as 50 m or more, and a silent section of 30 ms or more is created between the signals.

Now, this DTMF signal can be used not only as the aforementioned dial signal but also as a simple data transfer means, as can be seen from the fact that it is used for train and airplane reservations. Of course, it is not suitable for large-scale, high-speed data transfer, but
If it is about 100 words as in this embodiment, it is about 1 minute at most, which is sufficient for practical use.

Now, when sending a message, the telephone number and identification code are unique to the device and do not need to be selected, but the fixed phrase and sender's name must be selected. This is done by the user operating the keys on the operating section 13. However, it is not always necessary to select a fixed form sentence or sender's name. Moreover, conversely, it is also possible to select a plurality of items and send them out.

Here, the explanation will be given assuming that #0 in FIG. 8 is selected as the fixed form sentence and #4 in FIG. 9 is selected as the sender name.

The procedure for transmitting data is to first arrange the telephone number, identification code, fixed form sentence, and sender's name as shown in FIG. At this time, TN=Telephone Number: Telephone number ID=Identification Cod
e: For identification: l-1<N M = N ame
:Sender name MS=Message
: A special character indicating a fixed form sentence is placed at the beginning of each block, and STX (S
tart ofText: JI38 unit code 02 (1, 6)) and ETX (Endof “I”,
Insert ex+ 03 (+6)). These special characters are not commonly used in JIS8 unit codes, such as 00(16) to 1. You can choose from F(+6). Furthermore, in each block, meaningless characters, specifically, from the space following the last "non-space character" to the last space of the block, are deleted and the entire block is compressed, as shown in Figure 12. Make it. Note that if no fixed phrase or sender name is selected, “
NM” or “MS” and “S T X”
, “ETX” are also deleted. The same applies if the fixed form sentence or sender's name are all spaces. Conversely, if multiple fixed phrases or sender names are selected, they will be displayed in the order in which they were selected.
Or arrange them in ascending order of numbers (#0 to #7).

Therefore, a block of the sender's name is created for the sender's name, and a block of the fixed form is created for the fixed form.

Now, as shown in Figure 12, the compressed character string and DTM
This is encoded into an F signal, and a combination of DTMF signals can be used to remotely control the tape recorder, such as playing messages, and set various motes from an external telephone. Therefore, it would be bad to be confused with these signals, so please take care not to interfere with them.
For example, it is necessary to prepare a signal system as shown in Figure 12. This makes each character a three-digit I) T
The MF signal examples are "TN" and "TD" defined earlier.

Since "NM" and "MS" are important delimiters, it would be safer to use them as special signals. Therefore, the first
These will be assigned to /l-0 to /l-0 to 43 in Figure 3.

Therefore, for example, it is converted to 1] [I U Mewakoguchi'Kawaguchi'mon lromon■. That is, all courts are represented by a three-digit signal string. By the way, in the example shown in Figure 12, the total number of characters in the message to be sent is 69, and the ■ character is converted into three DTMF signals, so if one DTMF signal is sent in 120 m s. , 69x3x0.12=24. ．． This means that a total message can be sent in 84 [seconds]. In this way, the 12th
The character string shown in the figure is sequentially converted into 1) TMF signals and sent to the line.

In addition, the other party may request phone number, identification code, sender name, etc.
When an instruction to send a fixed form message is sent as a DTMF signal (transmission request Re-TN, Re-ID.

Re -N M , Re -M S, etc.), for example, if "Re -N M" is sent, the first
The “N M ” coat is searched from the data shown in FIG. 2, and the next data between STX and ETX is sent in the same manner as above. This is used to retransmit data if the line condition is poor and data cannot be received accurately.

For example, if a fixed form sentence is not selected and there is a request to send a fixed form sentence (R, e - M S ), we will send a null character (rlul) - character section I drive X. I'll keep it.

In addition, the control unit stores a data string inputted through key operations on the operation unit 13 or other communication in the memory 14 as TX (extra-text), and stores it in the memory 14 as TX (extra-text).
The function to be sent to the line can be selected using the operation unit 13 in the same manner as the sending of ".".The TX is also used for undefined texts and fixed-form messages sent from another telephone set, which will be described later.

To receive a message, the conversion table shown in FIG. 13 is used in reverse to convert the DTMF signal into a JI38 unit code.

The flow of message reception in this embodiment will be explained using FIG. 19.

Then, the control unit 1 receives the "TN" again in step 59.
05), it is again determined whether the data of "TN"' is normal (step 5906). If the data is abnormal again, leave “T N ” blank (step 5907).
.

The control unit 1 has codes T D ”, “N M ”,
“M S ” is also searched in the same way as “TN” (steps 8908 to 5925).

If it is determined that all the data have been correctly received, the control unit 1 reads the time from the clock 15 (step S3).

The received data, the received time read from the clock 15, and if there is a message as described later, the recording start coordinates are combined into one block and stored in the memory 14 (step S4). .

(Calling side behavior) The operation of the calling side will be explained using FIG. 22.

When the calling side control unit 1 detects that the dial key on the operation unit 13 has been pressed (step 5201), the network control unit 1
6 to close the line (step 5202) and dial the other party's telephone number. Then, the control unit 1 monitors the line in step S204. ), and waits until the dial tone (specific dial tone) of the answering machine of the called party is received (step 5206). The specific dial tone indicates that the other party has the function of receiving digital data, and when the control unit 1 detects this (step 5207),
A message to that effect is displayed on the display unit 17 (step 5208).

After that, the control unit monitors the hook switch and the operation unit 13 (Step 5209), and when it detects whether m-yen is pressed (Step 5210) or on-hook (Step S21), the own telephone number and Send the identification code to the line (step S21.2. S2], 3)
.

Then, the control unit 1 prompts for the input of the sender's name, and determines the input data of the sender's name (step 5215).

If there is an error, an input error message is displayed (step 5216). If it is normal, the sender's name is converted into a DTMF signal and sent to the line (step 5217). The control unit 1 performs the same processing as in steps S21.4 to 5217 for fixed forms (steps 5218 to 5221).

When the control unit 1 receives a data retransmission command, it retransmits the data for which the retransmission command was issued (step 5223).
). If there is no retransmission command, disconnect the line (step 5)
224).

(Operation of Called Side) If the answering machine mode is set, the sequence shown in FIGS. 18 to 20 will occur.

When the control unit 1 detects by the clock 15 that the preset output time has arrived, it outputs the reception list (step 5802).

Further, when the control unit 1 confirms that the called person is called (step 580
3) Controls the network control unit 16 to close the line (step 5804). Then, the current coordinate values of the magnetic tape are detected by the rotation amount detector 6 and stored in the memory 14 (step 5805). If there is enough magnetic tape, the control unit 1 sends a response message #1 to the line urging the caller to send a message (step 5807). If there is not enough space on the magnetic tape, a response message #2 is sent to the caller informing them that it is not possible to record a message (
Step 5822).

After the control unit 1 finishes playing response message #1, (
Step S8], 0), sends a specific dial tone to the line (Step S81.1), and starts recording the message (Step 5812).

This dial tone is generally used by an answering machine to inform the caller that recording has started, but in this embodiment, the receiver is notified that it is a facsimile machine with an answering machine function and a facsimile machine configured as in this embodiment. A special frequency is used or a special modulation is applied to the signal before it is transmitted. If the calling party's telephone is also a facsimile machine having the configuration of this embodiment, the calling party's control unit will display a message when it detects that it has received this specific dial tone from the called party. 17 indicates that an identification code etc. can be sent to the other party. Now, when the caller sees this display, instead of hanging up the receiver when the message recording is finished, the caller should oD(
Press []■Same for El-4039). This is the 13th
This is the signal that corresponds to stop in the figure. When the control unit 1 receives the low signal (step S814), it stops the magnetic tape device 4 (steps S8], 5).

Incidentally, if the control section 1 on the transmitting side confirms the function of the other party by a specific tone from the receiving side, it automatically switches to the DTMF transmission mode. Also, if there is no tape left and the message cannot be recorded, you need to press m- (no J).

If o[] is not pressed at this time and the caller hangs up the handset (step 5813), when the control unit 1 detects that the handset has been hung up, the control unit automatically disconnects the line without disconnecting the line. Send a row to . After that, the operation is the same as if the fixed form sentence and sender name were not selected (step 58).
17 to 5820).

After pressing the second button, the caller enters the number of the sender's name from the pre-entered numbers #0 to #7, and also enters the fixed form message from #0 above.
- Select from #7 by operating the keys on the operation panel.

After that, when it is detected that the caller has hung up the handset, the phone number, identification code, sender's name, and fixed text are sent as described above, and the called party informs us that the sending has been completed successfully. If so, disconnect the line (step Sl). The called party uses the rotation amount detector 6 to detect the coordinates of the recording tape at the time when the first dial tone is sent and stores it (step 58).
05).

If the called party disconnects the line without transmitting the digital data message, the called party first stops the recording device 5 and leaves the telephone number and identification code to be sent blank (step S8).7. S8], 8), assuming that the sender's name and fixed form sentence were not selected (steps 5819 and 582).
0), stores the reception time and recording start coordinates of the magnetic tape. When the other party transmits [DB], first stop the recording device 5 (step S 8 +-5), and then prepare to receive the data. Data reception is performed as explained in FIG. When the reception of digital data is completed normally, a DTMF signal indicating normal completion is sent to the calling party and the line is disconnected (
Step Sl).

The received digital data is treated as one block, and the reception time, reception time, and recording start coordinates of the magnetic tape are stored in the block (step S4).

In this way, each time a call is received one after another, a message is recorded on the magnetic tape, and the corresponding digital data is received and recorded. If recording cannot be performed on magnetic tape, the caller disconnects the line before hearing the tone from the called party indicating the start of recording (step 5808.5).
823), it is not recorded, and if the magnetic tape does not have enough remaining space to record, a special value such as oooo is entered in the data indicating the coordinates of the magnetic tape at the time of recording start (step 882). ],,S2.S],0.S
]l).

In addition, after receiving the above data in mode selection,
You can also immediately print in the format described below.

Further, if even one data set of digital data such as "double series" is saved, the control section 1 displays this on the display section 17. In this way, the user does not have to execute an output command as described below even though there is no data, so it can be said to be kind.

(Output of reception list) The output of the reception list will be explained using FIG. 23.

When the control unit 1 detects that the answering machine mode is canceled (step S301) or that the output of digital data is instructed by key operation on the operation unit (step 5302), the control unit 1 performs the following operations, for example. The data is output from the recording unit 11 in a format (step 5305).

Same■T Summer Nori-Field I Page I-Doreika I Sanshita I received a phone call from Mr.

- 口]

If there is no sender name, "n" is deleted. In addition, if there is no fixed phrase, delete "It's about the farm Ymata." If there is no phone number or identification code, leave it blank. If a message corresponding to the message has been recorded, "Index is rMJ Tez'" is added. If you cannot record because there is not enough space on the magnetic tape, add ``Unable to record.''

After outputting all the data, the control unit reads the current time from the clock 15 and records it from the recording unit 11.

If all data such as telephone number, identification code, sender's name, fixed form sentence, and message coordinate values are not present, the record will not be output. An example of the output is shown in FIG.

In addition, when the area for storing these digital data in the memory 14 becomes full, or when the control unit 1 detects that the number of received items has reached a predetermined number (step 5303), or when the clock 15, when it is detected that the output time has come, this function may be automatically activated.

Note that the data may be erased after it has been output to the recording section, and the control section 1 uses the coordinate values and data of the magnetic tape that the user inputs from the operation section 13 when reproducing a message as described later. It is also possible to compare the coordinate values within the block and erase the data if they match.

The user of the device can look at the list outputted from the recording section as shown in FIG. 14, infer the degree of urgency from the fixed phrases, etc., and check items in the order of importance. If the message is recorded, the index listed in the list shown in FIG. 13, that is, the leading coordinate value of the recorded portion of the message on the magnetic tape is input from the operation unit. For example, if the operating section 13 of this apparatus is as shown in FIG. 17, the block 20 related to control of the magnetic tape device
After pressing the index key 21 inside, enter the 4-digit index number (coordinate value). The control unit 1 compares the current coordinates of the magnetic tape and operates the magnetic tape drive device 5 in fast forward motion so that the coordinates match the input coordinate values. When the two values match, fast-forwarding is stopped, the system switches to playback mode, and the recorded audio is played back.

When the user of this device does not want others to know the contents of the message, the user manages the message using a password. In that case, the 14th
The output of the reception list and playback of recorded messages as shown in the figure now require input of a password. That is, when the control unit 1 detects that a password has been input from the operation unit 13, it outputs a list.

In addition, when the user wants to prevent a part of the message or a part of the reception list from being seen by others, the user can set the operation section 13 to erase mode and detect that the leftmost number of the reception list has been input. The corresponding data block is erased and garbage collected within the data area,
At the same time, the corresponding message on the magnetic tape is erased.

Furthermore, it is convenient to provide a function to output the above-mentioned reception list at a specific time on -day, since the daily reception status can be monitored (step 5304).

This is because the control unit 1 monitors the built-in clock 15 at appropriate times, and starts the aforementioned reception list output routine when the time coincides with a preset time.

In a system in which digital data is transmitted and received using a DTMF signal as in the device of this example, a message can be sent even if the transmitting side has the function of transmitting a DTMF signal. The format in this case is, for example, a DTMF signal. When the receiving side receives data in this format, it immediately outputs the contents of the message to the recording section.

(Simple communication using DTMF signals) Simple communication using DTMF signals will be explained using FIG. 21.

When the device responds by voice in step 5807 or 5822 of FIG. 18, the caller's unique personal identification number is input using, for example, the 88 box and the numeric keypad of the sending telephone. When the control unit 1 on the receiving side determines that this PIN number matches one of the PIN number list unique to the sender (step 510).
4. S], 05) and communicates the match to the caller (step S
], 08), Step S to identify the caller's name],
09), and stores the caller's name in the memory 14 (step 5IIO). In addition, in another area in the memory 14, there is a part for recording a fixed form message as shown in FIG. 16, and here, for example, a fixed form message as shown in FIG. The person knows the recorded contents and the corresponding numbers (#0 to #7).

When the caller learns from the sound or synthesized voice from this device that the PIN he or she entered has been confirmed (in this case, Hiroaki Matsumoto's PIN has been confirmed), one of the above-mentioned standard messages is sent to the caller. The selection of one or more of these is sent to this device in the following format, for example.

(This is when fixed message messages #2 and #6 are selected.) In other words, the control unit 1 on the receiving side monitors the line using the DTMF signal and sends the DTMF signal.
It checks whether a signal is being sent (steps S ], ], ], ), and if the sent data is determined to be valid (steps S1.13 to S1
15) Step S to save the data in the memory 14
], 17), informing the caller that the data is valid (step S1.1.8). If not valid,
The caller is informed of this (step 5119).

Valid data means that it is a DTMF signal specifying the fixed form message shown in FIG. 16 (step S1.1.5).
) or the D TMF signal itself (step 511
4).

When it is detected that the reception of the DTMF signal is completed and the line is disconnected (step 8120), if the data is valid (step S1.21), the time is read from the clock 15 (step 5122) and the reception time is determined. , the sender's name and the received data are output from the recording unit 11 (step 512
3).

When this device receives this, the recording device records '88104/

is printed.

In this way, it can be used as a simple memo or a remote message board.

[Second Embodiment] The configuration diagram of this embodiment is the same as the first embodiment shown in FIG. FIG. 24 shows a flowchart showing the operation of this embodiment.

When the control unit 1 detects that the answering mode is set by the user using the operation unit 3 (step 34, 01
), waits until there is a call from the line (step S
402). When the controller detects a call, it closes the line, and when the rotation amount detector 6 determines that there is sufficient storage capacity of the magnetic tape (step S404), it sends a message to the caller. , response message #
1 is sent (step 8405). Then, a specific dial tone is sent to the line to notify the calling party that it is the telephone of this embodiment (step 5406). Then, in step 540, the coordinate values of the magnetic tape are registered in the memory 14.
7), as the playback start position for later playback.

Then, the message from the calling party is recorded (step S409).

When the caller finishes sending the message, he or she presses the # key on the operation unit if the matter is urgent, and goes on-hook without pressing the # key if the matter is not urgent. When the control unit 1 on the calling side detects on-hook, it stores the memory 14
The caller information, which consists of the own telephone number and identification code, is read out from the terminal, converted into a voice signal such as a DTMF signal, and output to the line.

When the control unit 1 on the called side detects that the # DTMF signal has been received, it determines that there is an emergency. Further, the source information is received and restored from the DTMF signal (step 54).
10). Then, read the current time from clock 15 (
Step S4-]], ), the sender information 1 time, coordinate values, and whether or not it is an emergency are registered in the memory 14 (Step 34]2).

After that, the control unit 1 determines whether there is still sufficient storage capacity in the memory 14 (step S413).
). If there is not enough room, the data stored in the memory 14 is outputted by the recording unit 11 (step S4).
.

At this time, after finishing recording the data, the current time is read from the clock 5 and is recorded by the recording section 11 after the above data.

In step 5404, the control unit 1 sends a response message #2 to notify the calling party if there is not enough space in the magnetic tape storage capacity (step 84).
15). Then, in order to make it clear that recording will not be performed on the magnetic tape, the control unit 1 enters the coordinate values of the magnetic tape with "
**” (step 5416). Then, the process proceeds to step 5410 without recording the message.In this way, even if the calling party cannot record the message on magnetic tape, the calling party can register the calling party's information. It's coming.

When the control unit 1 detects that the answering mode has been canceled in step 5401 and there is data to be outputted in the memory 14 (step 5420), the control unit 1 performs step 54.
Similarly to step 14, the data is recorded together with the time at the time of output (step 34.21). Thereafter, it operates like a normal telephone (step 5422).

The user looks at the output recording paper, selects a message to be played from among those with a high degree of urgency or messages recorded on magnetic tape by the caller, and inputs coordinate values from the operation unit 13. Enter. Control unit] 1 controls the tape drive unit 5 to rewind to the input coordinate values and reproduce the message.

〔Effect of the invention〕

As described above, according to the present invention, by outputting the sender information and the recording start position, it is possible to notify the user of the sender of the recorded message and the recording start position. Therefore, it is possible for the user to select a message that needs to be played back preferentially from among the recorded messages, and furthermore, it is possible to start playback from the recording start position.
