Description

Description: TECHNICAL FIELD The present invention relates to an answering machine capable of reproducing only a message from message messages and busy tones recorded during absence.

(Prior Art) A conventional answering machine sends a response message when an incoming call is received from the other party's phone in answering machine, and then hangs up without talking a message or anything sent from the other party. The busy tones emitted to the recording medium are recorded on a recording medium such as a magnetic tape in the order of arrival. Then, when the user of the answering machine performs a predetermined reproducing operation after returning home, the records in the absence can be reproduced in order from the beginning, and all the records in the absence can be heard.

By the way, when this type of answering machine is installed, it is general that the message and the busy tone are randomly recorded in the answering mode because the other party who receives the response message has various responses. . For this reason, when the playback operation is performed and the recording is heard from the beginning, the busy tone must be heard in addition to the message. Although this busy tone conveys the fact that there is a telephone call, it is bothersome for the user and also causes a long listening time.

Therefore, when a busy tone is recorded in the absence mode, an answering machine equipped with a function that rewinds the magnetic tape by using this busy tone as an invalid message and cue the tape to record a new message is available. Proposed.

(Problems to be Solved by the Invention) However, in the above answering machine in which the busy tone is disabled, if the other party who receives the response message talks for a few seconds and then hangs up,
Since the call time is short, it may not be possible to distinguish between the business message and the busy tone, and the message may be erroneously recorded as the busy tone. That is, there is a problem that the message is invalid as a busy tone even though it is a short message.

By the way, voices can be identified to a person who is accustomed to listening by just listening to a few words. Therefore, if the message for a short time is invalid and not played as described above, it is completely unknown who the other party of the call is, and the incoming call status cannot be grasped, and the utility value as an answering machine is significantly reduced. It was something that caused it.

Also, in the above-mentioned conventional answering machine, the busy tone is not recorded, but when you want to know the number of incoming calls while you are away, even though the busy tone is a signal indicating the number of incoming calls, the busy tone is not recorded. Exclusion is not preferable.

The present invention has been made in view of the above circumstances, and an object of the present invention is to shorten the listening time by allowing only the message of the message and the busy tone recorded in the absence mode to be reproduced. , It is to provide an answering machine that enables listening to short messages, etc., and can know the number of incoming calls even when only busy tone is recorded.

(Means for Solving the Problems) In order to solve the above problems, the answering machine of the present invention is
In response to an incoming call from the other party's telephone, the response message stored in the storage medium in advance is sent to the other party, and the message sent from the other party after the sending and the other party hangs up silently. In the answering machine that is configured to record the output busy tone in the recording unit and reproduce the message message and the busy tone recorded in the recording unit in response to the reproduction instruction signal from the reproduction operation unit, in the answering mode. A busy tone detecting section for detecting a busy tone sent from the side telephone, and a counting section for counting the recording start value position and the recording end position of the message recorded in the recording section,
The storage unit stores the count value of the message by the counting unit as count data, and stores the data indicating that the busy tone is present when the busy tone is detected by the busy tone detecting unit, and the message message recorded in the recording unit. From the message reproduction operation unit, a message reproduction operation unit for transmitting an instruction signal for reproducing only the recorded message, a recording content reproduction operation unit for transmitting an instruction signal for reproducing all of the message message and the busy tone recorded in the recording unit, and the message reproduction operation unit. While reading the count data of the message and the data indicating that there is a busy tone from the storage unit based on the instruction signal of, while skipping the busy tone recorded in the recording unit based on the read data indicating the presence of the busy tone, Based on the read count data The first control section for reproducing only the message message recorded in the recording section, and all the message messages and busy tones recorded in the recording section in sequence based on the instruction signal from the recording content reproduction operation section. A configuration including a second control unit for reproducing is adopted.

(Operation) With the above configuration, when the other party who receives the response message announces the message, the message message sent from the other party is recorded in the recording section, and the message message is recorded in the recording section. The start position and the recording end position are counted by the counting unit, and the count data is stored in the storage unit.

On the other hand, when the other party hangs up the telephone without receiving a response when the response message is received, the busy tone emitted at that time is recorded in the recording unit and the data indicating the busy tone is stored in the storage unit. Thus, the message and the busy tone are randomly recorded in the answering machine, and the count data of each message and the data indicating the busy tone are stored in the storage unit.

After this, when the user listens to the record while he is away,
When the message reproduction operation unit is operated, the count message and the data indicating that there is a busy tone are read from the storage unit in response to the reproduction instruction signal. Then, the first control unit reproduces only the message message recorded in the recording unit based on the read count data while skipping the busy tone recorded in the recording unit based on the read data indicating the presence of the busy tone. .
As a result, the busy tone is not reproduced and only the message of interest is sequentially reproduced so that the message can be heard.

In addition, when recording the message, even messages for a short time are recorded and counted as a message, so that when the message is reproduced, all messages are reproduced and can be heard. There is.

When the user operates the recorded content reproduction operation section, the second control section sequentially reproduces all the message and the busy tone recorded in the recording section based on the instruction signal. As a result, it is possible to know the number of incoming calls even when only the busy tone is recorded.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an electrical configuration of an answering machine according to the present invention.

In the figure, a telephone line 1 is connected to a chip ring 2 which is an input / output terminal, and a communication circuit, a hook switch, a handset, etc. are connected to the chip ring 2 although they are not shown. .

There is.

The output of the line closing circuit 3 is connected to the busy tone detecting circuit 5 and the answering / answer recording unit 6. The busy tone detecting circuit 5 is provided with a pulse converting circuit, and the busy tones b1, b2, b3 sent from the telephone line 1 as shown in FIG.
Are converted into pulse waves P1, P2, P3 ... and given to a busy tone detection unit 15 described later. The answering / answer recording unit 6 is a recording / reproducing device, and is known as an ic recording-ic recording system, an ic recording-tape recording system, a tape recording-tape recording system, and the like. In this example, the tape recording-tape recording method is adopted, and in the absence mode, the response message is reproduced and transmitted, and the message messages M1, M2, M3 ... and the busy tone B1, B2 transmitted from the telephone line 1 are transmitted. ,
B3 ... is recorded on the magnetic tape as Message 1, Message 2, Message 3 ... (see FIG. 3).

The reproduction switch 7, which is a message reproduction operation unit, sends out an instruction signal for reproducing only the message of interest when pressed. Further, the reproduction switch 8 which is a recording content reproduction operation unit sends an instruction signal for reproducing the entire record including the message and the busy tone by the pressing operation, and gives these instruction signals to the switch detection unit 16 of the microcomputer 9. It is like this.

The control section 10 controls the operation of each section of the answering machine and also controls the recording / playback operation at the time of answering machine. The control section 10 detects an incoming signal from the incoming call detection circuit 4. A count unit that detects the output of the incoming call detection unit 11 that outputs data and the start count value and the end count value that indicate the start position and the end position of the message recorded on the magnetic tape of the answering / answer recording unit 6.
14 and the output of a busy tone detecting section 15 which receives the detection signal from the busy tone detecting circuit 5 to count the number of busy tones, and a switch detecting section 16 which detects a reproduction instruction signal from each of the reproduction switches 7 and 8. Output is connected. Further, from the control unit 10, the line closing circuit 3
A control signal is sent to each of the line closing unit 12 that sends a switching signal and the answering reply control unit 13 that sends an instruction signal to the answering sound recording unit 6. Further, the control unit 10 is bidirectionally connected to a storage unit 17 that stores the count value of the counting unit 14 as count data and also stores the data indicating that there is a busy tone from the busy tone detecting unit 15.

 Next, the operation of the answering machine having the above configuration will be described.

First, it is assumed that the answering machine is set in the answering machine. When a ringing signal is sent through the telephone line 1 in this state, this ringing signal is guided from the chip ring 2 to the incoming call detection circuit 4, where an incoming call is detected. And
The incoming call signal sent from the incoming call detection circuit 4 is input to the incoming call detection unit 11 of the microcomputer 9. Incoming call detector
At 11, the number of incoming calls is counted, and when a preset number of times is counted, a detection signal is sent to the control unit 10. The control unit 10 determines the line closing unit 12 based on this detection signal.
A control signal is output to the circuit closing circuit 12, and a switching signal is output from the circuit closing unit 12 to close the circuit closing circuit 3.

Next, the control unit 10 outputs a control signal to the answering machine response control unit 13, causes the answering machine response control unit 13 to output an instruction signal, and activates the answering machine recording unit 6. As a result, a response message is output from the answering / answer recording unit 6, and the circuit closing circuit 3,
It is sent to the other party's telephone through the chip ring 2 and the telephone line 1. When the other party receives the response message and gives a message, this message is guided to the answering / answering recording section 6 via the telephone line 1, the tip ring 2 and the line closing circuit 3 to record the answering / answering message. It is recorded on the magnetic tape in the section 6. At this time, the count unit 14 sends the count value indicating the start position and the count value indicating the end position of the tape when the message is recorded on the magnetic tape to the storage unit 17 via the control unit 10. This allows
The start position and the end position of one message are stored in the storage unit 17 as count data.

Subsequently, when a call signal is received from another party, a response message is similarly sent out. When the party receiving the response message hangs up silently after listening to the response message, the busy tone is sent via the telephone line 1. Will be sent. This busy tone is guided to the busy tone detecting circuit 5 via the line closing circuit 3. The busy tone detection circuit 5 converts the guided busy tone into a pulse signal, and supplies the converted pulse signal as a detection signal to the busy tone detector 15 of the microcomputer 9.
Upon receiving this detection signal, the busy tone detecting section 15 counts the busy tone a preset number of times (for example, a few times), and then sends an output signal to the control section 10. Control unit 10
The control signal is sent to the line closing unit 12 and the answering machine response control unit 13 based on this output signal. That is,
The line closing unit 12 sends a switching instruction signal based on this control signal to the switching control input of the line closing circuit 3 to open the line closing circuit 3, and the answering machine response control unit 13 sends this control signal. A stop instruction signal based on is sent to the answering / recording section 6 to stop the operation of the answering / recording section 6. As a result, the busy tone is recorded on the magnetic tape in a predetermined time width. At this time, the busy tone detection unit 15 sends data indicating that there is a busy tone to the storage unit 17 via the control unit 10. Thereby, the data indicating one busy tone is stored in the storage unit 17.

In this manner, every time there is an incoming call, the message M1, M2, M3 ... And the busy tone B1, B2, B3 ... are recorded in the order of arrival, as shown in FIG. 3, and the message M1, M2, M3 is recorded. …
Will be recorded with a time width according to the length of the other party's message (see FIG. 3).

After this, when the user of the answering machine who returns home presses the playback switch 7 to listen to the message recorded while he / she is away, the switch detection unit 16 controls the signal instructing the playback of only the message. Given to part 10. Upon receiving the instruction signal, the control unit 10 reads the count data of the message and the data indicating the busy tone from the storage unit 17. Then, the control signal for instructing the reproduction of the portion of the magnetic tape corresponding to the read count data and the skip of the portion for the data indicating the presence of the busy tone are sent to the answering machine response control section 13. Based on this control signal, the answering machine response control unit 13 sequentially sends to the answering machine recording unit 6 an instruction signal including a start value and an end value for rewinding the magnetic tape and reproducing only the message. As a result, the reproduction / stop of the magnetic tape of the answering / answer recording unit 6 is controlled based on the count data, and the message messages M1, M2, M3 are skipped while skipping the busy tone recorded on the magnetic tape.
... plays back only one by one. Since this reproduction signal is supplied to a speaker (not shown), the user can listen to a plurality of messages in which only the message of interest is reproduced. As a result, the listening time for messages is greatly reduced.

Further, according to the present invention, even if the message of the other party is short, for example, even if it is completed in a few seconds, it is recorded as a message, so that it can be heard all at the time of playback, so even if the message is short, it is not familiar The other party's voice can easily determine the other party.

It should be noted that when the reproduction switch 8 is operated during reproduction, all the messages are reproduced, so that it is possible to know the number of incoming calls including the busy tone.

(Effects of the Invention) When the message message is sent from the other party, the answering machine of the present invention stores the count value counted as the message message in the storage unit as the count data and also sends the busy tone. Then, the detection signal is stored in the storage unit as one of the messages, and at the time of reproduction, by operating the message reproduction operation unit, the count data and the data indicating that there is a busy tone are stored in the storage unit. Based on the configuration, only the message is played back while skipping the busy tone, so that the listening time can be shortened by the time when the busy tone recorded by the other party hangs up silently. Also, by operating the recorded content playback operation section during playback, all the message messages and busy tones recorded in the recording section are played back in sequence.
It is possible to know the total number of incoming calls in the absence mode, including the case where only the busy tone is recorded.
