Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more specifically, starts recording the contents of a telephone call at the same time as an incoming call or an outgoing call,
The present invention relates to a telephone having a recording / reproducing function, which allows a person who makes a call after the end of a call to judge whether or not to save the recorded content, and efficiently save only the important call content.

[0002]

2. Description of the Related Art Conventionally, a recording / reproducing function of a telephone is used when a person having the telephone (hereinafter referred to as "caller" regardless of whether to call or to receive the call) receives a call when he / she is not present. However, this is what is called an answering machine function. The answering machine function counts the number of ringing tones of the incoming telephone, and when a certain number of times is reached, the playback unit operates and plays back the message previously recorded by the caller. Is popular in Known examples showing such a conventional technique are disclosed in Japanese Patent Laid-Open No. 6-291830 and Japanese Utility Model Laid-Open No. 6-48268.

[0003] Further, conventionally, a person who has a telephone at a distant place through a station line (hereinafter, referred to as an "external caller" regardless of whether the other party makes a call or receives a call).
Many malicious and malicious prank calls have occurred recently, and an attempt is made to recognize nuisance calls and prank calls by recognizing the telephone number of a specific external caller who has called to counter this. Has been done. Known examples showing such a conventional technique are disclosed in JP-A-6-244944 and JP-A-6-253004.

[0004] In recent years, solicitation using a telephone or the like has become popular, but some of them are malicious and sometimes solicited skillfully. Many people have been damaged by such commercial law. Therefore, there is an increasing need to record the call contents of the telephone and record and save the call contents.

[0005]

Therefore, a telephone capable of recording the contents of a call is required, but many telephones installed in a general home may not have a function of recording all the contents of a received call. Many. Further, it is judged by a person based on the call contents whether the call contents are recorded or not. However, if you record by pressing a switch etc. when you think it is important, the important part is missing, so it is necessary to reiterate the important content. Also,
If you forget to press a switch, you cannot record. As described above, there is a drawback in that it may not be possible to record the content of a call that is desired to be made by leaving a record. In addition, since it is determined whether to record or not depending on the content of the call, it is necessary to press the recording switch each time a call is received, which is complicated and troublesome.

Further, when the recording medium is a magnetic recording medium such as a microcassette tape or a compact cassette tape, it is said that a continuous call is made before there is time to erase unnecessary call contents, and then the call is made. I have no choice but to record. Further, if the call is an important call content, there is a drawback that the previously recorded call content cannot be deleted.

[0007]

In order to solve the above problems, in a telephone set according to claim 1, a handset, a voice signal of a caller inputted through the handset and an external call inputted through a telephone line. A voice signal synthesizing unit for synthesizing a voice signal of a person, a recording unit for recording the synthesized voice signal output from the voice signal synthesizing unit, a recording medium used for recording by the recording unit, and a recording medium for receiving or transmitting a call. A recording unit for recording on the recording medium; a unit for ending recording on the recording unit after the call ends and the call state is released; and a case where the call content is recorded and stored, the call is recorded on the recording medium. A control unit having means for prohibiting overwriting of the contents, and means for permitting overwriting of the contents of the call on the recording medium when the contents of the call are not recorded and saved;
It has at least a selection input unit which is connected to the control unit and inputs to the control unit whether or not to save a record of the content of the call.
According to a second aspect of the present invention, in the telephone according to the first aspect, there is provided a display section for displaying a message for inputting recording and storage of call contents. The telephone according to claim 3, wherein in the telephone according to claim 1, the voice signal synthesizing unit is a reproducing unit that reproduces a voice signal of a caller input through the handset and the content recorded by the recording unit. To the speaker of the handset, an external output means for outputting a signal obtained by synthesizing the reproduced signal of No. 1 to an external line, and a signal obtained by synthesizing the voice signal of the external caller input through the telephone line and the reproduced signal from the reproducing unit. It has at least speaker output means for outputting. The telephone according to claim 4 is the telephone according to any one of claims 1 to 3, wherein the recording medium is an optical disk or a magneto-optical disk capable of recording and reproducing, and the recording section and the reproducing section record and reproduce. It is a drive unit for an optical disk or a magneto-optical disk that can be used.

[0008]

According to the telephone having the recording / playback function as described above, since all the telephones are recorded at the same time as the incoming call, the call contents are not missed. The data is recorded and saved or erased by the operation of the selection input unit such as a button according to the judgment of the caller.

Further, since the display unit in which characters and the like blink is provided so as to call out whether or not to record the contents of the call, the situation of forgetting to input the record of the contents of the call is reduced.

In addition, the signal recorded in the recording unit and the voice signal of the caller are combined so that the caller can hear the signal, and the signal recorded in the recording unit and the voice signal of the caller The caller can hear the synthesized signal through the speaker of the handset. As a result, the caller and the external caller can hear the contents recorded before this call during the call.

Further, since the recording medium is a recordable / reproducible optical disk or magneto-optical disk, quick access can be realized. As a result, even if a call is continuously received, the necessary call contents can be overwritten in the place where the unnecessary call contents are recorded, so that the recording medium is not wastefully used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a general external block diagram showing an embodiment of a telephone according to the present invention. The handset 1 is connected to a telephone body 3 through a cord 2. Handset 1
Indicates that during normal times, the hook 4 provided on the telephone body 3 is pressed, and the telephone is not receiving a call. The telephone body 3 is provided with a ten-key portion 5 for inputting a telephone number and a selection input portion 6 for inputting whether or not to keep a record. The display unit 7 displays information and operation methods according to the keys of the selection input unit 6. A station line 8, which is a telephone line, is connected to the telephone body 3, and an incoming signal and a voice signal from an outside caller are sent through the station line 8.

An optical disk or a magneto-optical disk capable of recording / reproducing and a drive section thereof are provided in the main body of the telephone as an MD recording section 9 and an MD.
It is mounted as the reproducing unit 10. In the telephone according to this embodiment, a mini disk (hereinafter referred to as "MD") which is a magneto-optical disk housed in a cartridge will be described as an example. However, it goes without saying that a phase change type optical disk or another magneto-optical disk which is not housed in a cartridge does not hinder the purpose of the invention.

When the reproduction key of the selection input section 6 is pressed, the MD reproduction section 9 reproduces the recorded contents. In this embodiment, one call is further defined as one track, the pickup is moved forward,
Automatic search forward key (# key) to search for the desired track, automatic search reverse key (* key) to move the pickup backward to search for the desired track, and manual search forward key to fast-forward the content of the call being played. (9 key) and manual search reverse key (7
Key). When these various keys are pressed during reproduction, the search function as described above operates and the reproduction of the call contents becomes easier. When the stop button of the selection input section 6 is pressed, the reproduction is stopped.

FIG. 2 shows an internal block diagram of a telephone which is an embodiment of the telephone of the present invention. The following configuration is used to let external callers hear the recorded contents. The microphone 11 for converting the voice of the caller of the handset 1 into an electric signal is connected to the first voice signal processing unit 12 through the cord 2, and the first voice signal processing unit 12 is connected to the first voice signal synthesizing unit 13
Is connected to one end. Further, the MD reproduction unit 10 equipped with the reproduction MD 14 is connected to the other end of the first audio signal synthesis unit 13 through the second audio signal processing unit 15. The recorded voice and the synthesized voice signal of the caller are the first voice signal synthesizer 1
3, and a voice signal is sent from the station line 8 to the telephone of the outside caller through the third voice signal processing section 16 and the station line closing section 17. In this way, since the contents recorded before this call can be reproduced and heard during the call, new applications such as confirming the promise with the third party and sending a message to the third party can be expected.

The first, second and third signal processing sections are provided to match the recording level and the signal format. For example, when the voice signal from the microphone 11 of the handset 1 is an analog signal and the voice signal on the office line, which is a telephone line, is a digital signal, it is necessary to unify the recording signal as an analog signal or a digital signal. To an analog audio signal. In addition, the audio level is adjusted to prevent the situation where one audio cannot be heard. As described above, since the signal formats are unified by the first, second, and third signal processing units and output from the first, second, and third audio signal synthesis units, the output signal is the local line 8 It is possible to obtain the correct signal required for each output section. For the sake of convenience, the signal format is as described above in this embodiment, but it goes without saying that the configuration of the present invention is not affected by the signal format.

Similarly, in order to record the contents of the call between the caller and the external caller, the following configuration is adopted. The microphone 11 for converting the voice of the caller of the handset 1 into an electric signal is connected to one end of the second voice signal synthesizer 18 through the cord 2 through the first voice signal processor 12 inside the telephone body 3. The voice signal from the caller of the other party is connected to the other end of the second voice signal synthesizing unit 18 through the telephone line 8, the line closing unit 17, and the third voice signal processing unit 16 which are telephone lines. A synthetic voice signal, which is the content of the call between the caller and the external caller, is output from the second voice signal synthesizing unit 18, and is voiced through the second voice signal processing unit 15 to the MD recording unit 9 in which the recording MD 19 is mounted. A signal is sent and the content of the call is recorded in the recording MD 19.

Further, in order for the caller to hear the recorded contents of the reproducing section and the voice of the external caller simultaneously from the speaker 20 of the handset 1, the following configuration is adopted. MD playback unit 1
0 is connected to one end of the third audio signal synthesizer 21 through the second audio signal processor 15. A voice signal from an external caller is connected to the other end of the third voice signal synthesizing unit 21 through the telephone line 8, the station line closing unit 17, and the third voice signal processing unit 16. The synthesized voice signal of the external caller and the recorded content is output from the third voice signal synthesis unit 21, and the voice signal is sent to the speaker 20 of the handset 1 through the first voice signal processing unit 12 so that the voice can be heard.

A servo controller 22 connected to the MD recording unit 9 and the MD reproducing unit 10 for controlling a servo system, a ten-key unit 5 for inputting a telephone number, selection of whether or not to record a call content, deletion of a record, and recording content A selection input section 6 for reproducing, a display section 7 for displaying information of recorded contents by displaying characters and the like, and a hook 4 are mechanically or electrically connected, and when the hook 4 is pressed, the local line is connected. Control unit 2 to the incoming line detection unit 24 to which the station line closing unit 17 that closes the connection of
5 are connected to each other. The control unit 25 performs system control regarding the operation between each device.

FIG. 3 is a flowchart of system control which is an embodiment of the telephone of the present invention. Step S1 shows a step indicating the start of the flowchart. Step S
2 is a step of detecting an incoming signal. When the incoming call detection unit 24 detects an incoming call signal and a ringing tone is sounding, or when a caller lifts the handset 1 from the telephone body 3,
The state where the hook 4 is opened and the office line closing part 17 is connected is shown. If there is no incoming call, repeat step S
Do 2

Step S3 is a step of recording a call. At this point, recording is started regardless of the content of the call or the outside caller. As a result, the MD recording unit 9 always performs recording, and there is no human judgment as to whether or not recording should be performed. Step S4 is a step of detecting a signal when the hook 4 is pressed at the end of the call. When the hook 4 is pressed, the station line closing part 17 releases the connection,
The control unit 25 detects this release. If the hook is not pushed, step S4 is repeated until it is detected. This signal is also detected when the delete key of the selection input unit 6 is pressed during a call.

Step S5 is a step of stopping the recording of the call. When the hook 4 is pressed by the handset 1 or a human hand, the control unit 25 sends a signal to the servo controller 22 to stop the recording, and the MD recording unit 9 stops the recording. As a result, unless the delete key of the selection input unit 6 is pressed, all the call contents are recorded from the beginning to the end. Step S6 is a step of urging the display unit 7 to save the record. Display 7
Is an LCD (Liquid Crystal Display)
ay) and the like. By using a method of displaying a character or the like that calls for recording on the display unit 7 or a method of blinking this display, the accuracy with which the selection input is performed is increased. Although the method using the display unit 7 is described here, for example, the selection input unit 6
LE attached to the selection input section 6 by making the character part of
It is also possible to use a method of lighting or blinking the D section, a method of providing another LED lighting section in the telephone body 3 and lighting it. As a result, the caller is urged to make a selective input, so that the situation of forgetting the input is reduced.

Step S7 is a step of inputting from the selection input unit 6 to decide whether or not to save the recorded contents. If there is no input from the selection input unit 6, the process jumps to step S8, and if there is input from the selection input unit 6, the process jumps to step S9. Step S8
Is a step of determining a timeout. Even if there is no input from the selection input unit 6 for several minutes, the process returns to step S7 and waits for selection input, but if there is no input from the selection input unit 6 even after several minutes, it is determined that a record is to be left. Then, jump to step S10. Even if it is not necessary, it can be deleted at a later date according to the information displayed on the display unit 7 by using the delete key of the selection input unit 6.

Step S9 is a step of judging the contents of the selection input section. If the record key of the selection input unit 6 is pressed, the process jumps to step S10, and if the delete key of the selection input unit 6 is pressed, the process jumps to step S11. Step S10 is a step showing a procedure when the record is saved by the selection input or when the selection input is not made. In this case U-TOC
(User's Table Of Content
In s), enter information such that writing is impossible on the recorded contents. This prevents writing.

Step S11 is a step showing a procedure when the record is not saved. If a track is created immediately after the end of the call, information that allows writing is added to the recorded contents in the U-TOC to erase the existence of the track. If the track is not created until the selection input is made, the U-TOC is not changed and kept in the same state as before. As a result, since it is determined that this track does not exist in any of the cases, writing is performed in the next recording. Step S12 is a step indicating the end of the flowchart, and the process returns to the start of step s1 in the state of waiting for an incoming signal.

In this embodiment, the MD recording unit 9 and the MD reproducing unit 1
0 and 2 optical disk drive units are used, and the contents recorded in the MD recording unit 9 are recorded in MD in order to keep track of when the telephone is not in use.
If it is transferred to the reproducing unit 10, the recorded contents are always recorded in the reproducing MD 14, so that the usability is further improved. Further, although the MD recording unit 9 and the MD reproducing unit 10 have been described with particular distinction, the present invention can be implemented even with one MD recording and reproducing unit 9 and 10 each having a recording and reproducing function.

[0027]

As described above, according to the telephone of the present invention, since all the telephones are recorded at the same time as the incoming call, the call contents are not missed, and it is not necessary to make a complicated input for each telephone call. In addition, data by operating the input unit such as a button is recorded and saved according to the judgment of the caller. As a result, if the call is a malicious prank call or a nuisance call, the call content can be recorded and saved and provided to the police or other investigative agencies at a later date, or if the call content includes important promises, it can be used as a memo. it can.

Since it is a magneto-optical disk,
Access can be made faster than when using a cassette tape or the like. When a cassette tape or the like is used, it is a contact type, so pain due to abrasion or the like is fast, but a magneto-optical disk is a non-contact type, so it does not hurt as fast as the tape. Also, since it is a micro-cassette tape that is smaller than a compact cassette tape for music, it is not compatible with general machines, but magneto-optical discs are not compatible with general machines according to standards such as MD (mini disk) for music. It also has compatibility. Also, the recording time is longer than that of the cassette tape.
