Abstract

PURPOSE:To shorten listening time and to listen even a short message or the like as well by reproducing only a business message among business messages and busy tones recorded in an absence mode. CONSTITUTION:When an opposite party side receiving a response message tells the business, this business message to be sent from the opposite party side is recorded to a recorder part, and a count part counts the recording start and end positions of the business message to the recorder part. Then, the count data is stored in a memory part. On the other hand, when the response message is received and the opposite party side cuts off the telephone call without speaking anything, the busy tone to be generated at that time is recorded to the recorder part and data showing the busy tone is stored in the memory part. Afterwards, when a user operates a message reproducing operation part, the count data is read out from the memory part in response to a reproducing instruction signal. Based on this count data, a control part reproduces only the business message from the recorder part.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an answering machine that is capable of reproducing only business messages among business messages and busy tones recorded while the telephone is away.

(Prior art) Conventional answering machines send a response message when a call is received from the other party's phone while in answering mode, and then send a response message when the other party receives a message or hang up without speaking. The busy tones emitted by the telephone are recorded on a recording medium such as a magnetic tape in the order in which the calls are received. When the user of the answering machine performs a predetermined playback operation after returning home, the records recorded during the user's absence are played back in order from the beginning, making it possible to listen to all records recorded during the user's absence.

By the way, if you have installed this type of answering machine,
Since the responses of the other party to the response message vary, business messages and busy tones are generally recorded at random during the absence mode. Therefore, if the user performs the playback operation and listens to the recording from the beginning, he or she will have to listen to the busy tone in addition to the business message. Although this busy tone indicates that there is a call, it is bothersome to the user and also causes a long listening time.

Therefore, if a busy tone is recorded while in away mode,
An answering machine has been proposed which has a function of rewinding the magnetic tape by treating the busy tone as an invalid message, and then locating the beginning of the tape so that a new message can be recorded.

(Problem to be Solved by the Invention) However, in the above-mentioned answering machine that disables the busy tone, if the other party who receives the response message speaks for 2.3 seconds and then hangs up,
Because the duration of the call is short, it may not be possible to distinguish between business messages and busy tones, and they may be mistakenly recorded as busy tones.

That is, there was a problem in that even though the message was short, it was invalidated as a busy tone.

By the way, people who are used to listening to voices can identify someone just by hearing a few words. Therefore, if a short-time message is invalidated and not played back as described above, it is completely unknown who was on the other end of the call, and it is also impossible to know the status of the call, which significantly reduces the value of using it as an answering machine. It was something to do.

The present invention has been made in view of the above-mentioned circumstances, and its purpose is to shorten the listening time by making it possible to reproduce only the message from among the message and busy tone recorded during the absence mode. To provide an answering machine capable of listening to short messages, etc.

(Means for Solving the Problems) - In order to solve the above problems, the answering machine of the present invention has the following features:
In response to an incoming call from the other party's telephone, a response message pre-stored in a storage medium is sent to the other party, and after the response message is sent, a business message is sent from the other party, and the other party hangs up without saying a word. In an answering machine that is configured to record the output busy tone in the recording section and to play back the busy tone and busy tone that are recorded in the recording section in response to a playback instruction signal from the playback operation section, the answering machine is configured to a busy tone detection unit that detects a busy tone sent from the side telephone; a counting unit that counts a recording start value position and a recording end position of the business message recorded in the recording unit;
A storage section that stores the count value of the business message by the counting section as count data and also stores data indicating that a busy tone is present when a busy tone is detected by the busy tone detection section, and the business message recorded in the recording section. a message playback operation unit that sends out an instruction signal for reproducing only the message; and in response to the instruction signal from the message playback operation unit, count data of the business message is read from the storage unit, and based on this count data, the recording unit and a control section for reproducing only the recorded business message.

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

On the other hand, when a response message is received and the other party hangs up without speaking, the busy tone emitted at that time is recorded in the recording section, and data indicating that it is a busy tone is stored in the storage section. In this way, 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 section.

Thereafter, when the user operates the message playback operation section to listen to the recording during his/her absence, the count data is read out from the storage section in response to the playback instruction signal. Then, the control section reproduces only the business message from the recording section based on this count data. As a result, the busy tone is not reproduced, and only the business messages are sequentially reproduced so that they can be listened to.

Furthermore, when recording the business message, even short messages are recorded and counted as business messages, so when the business message is played back, all messages are played back and can be listened to. There is.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

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

3. Put the information 1. on the magnetic tape. Requirement 2. Business 3...
・(Refer to Figure 3)

The playback switch 7, which is a message playback operation section, sends an instruction signal to play back only the message when pressed, and the playback switch 8, which is also a message playback operation section, sends out an instruction signal to play back only the message and the busy tone when pressed. Instruction signals for reproducing all records are sent out, and these instruction signals are applied to the switch detection section 16 of the microcomputer 9.

The control unit 10 controls the operation of each part of the answering machine, as well as the recording and playback operations during the answering mode. A counting unit 14 detects the output of the incoming call detection unit 11 that outputs data, and the start count value and end count value that indicate the start and end positions of the business message recorded on the magnetic tape of the answer recording unit 6. , the output of the busy tone detection section 15 that receives the detection signal from the busy tone detection circuit 5 and counts the number of busy tones, and each reproduction switch 7.8.
The output of the switch detection section 16 that detects the reproduction instruction signal from the switch is connected.

Further, from the control unit IO, a line closing unit 12 that sends a switching signal to the line closing circuit 3, and an answer recording unit 6
A control signal is sent to the absence response control section 13, which sends an instruction signal to the office.

Further, the control section 10 is bidirectionally connected to a storage section 17 that stores the count value of the counting section 14 as count data and also stores data indicating the presence of a busy tone from the busy tone detection section 15.

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

First, assume that the answering machine is set to answering mode. When a calling signal is sent through the telephone line 1 in this state, the calling signal is guided from the tip ring 2 to the incoming call detection circuit 4, where the incoming call is detected. The incoming call signal sent from the incoming call detection circuit 4 is input to the incoming call detection section 11 of the microcomputer 9. Incoming call detection unit 1
1, the number of incoming calls is counted, and when a preset number of calls is counted, a detection signal is sent to the control unit 10. The control unit 10 outputs a control signal to the line closing unit 12 based on this detection signal, causes the line closing unit 12 to output a switching signal, and closes the line closing circuit 3.

Next, the control unit 10 outputs a control signal to the absence response control unit 13, causes the absence response control unit 13 to output an instruction signal,
The absence response recording section 6 is activated.

As a result, a response message is output from the answer recording section 6, and the line closing circuit 3, the tip ring 2, and the telephone diagram v
It is sent to the other party's telephone via Al. When the other party receives this response message and announces the business, this business message is led to the answering answer recording section 6 via the telephone line 1, tip ring 2, and line closing circuit 3, and the answering message is recorded. It is recorded on the magnetic tape in section 6. At this time, the counting section 14 sends to the storage section 17 via the control section 10 a count value indicating the start position of the tape and a count value indicating the end position of the tape when the business message is recorded on the magnetic tape. As a result, the starting position and ending position of one business 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 sent in the same way, and if the party receiving this response message hangs up without saying a word after hearing the response message, a busy tone is sent via the telephone diagram Ns1. will be sent. This busy tone is guided to a busy tone detection circuit 5 via a 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 to the busy tone detection section 15 of the microcomputer 9 as a detection signal. The busy tone detection section 15 receives this detection signal, counts the busy tone a preset number of times (for example, 2.3 times), and then sends an output signal to the control section 10.

Based on this output signal, the control unit 10 controls the line closing unit 1.
2 and the absence response control unit 13, respectively. 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 absence response control unit 13 sends a switching instruction signal based on this control signal to the switching control input of the line closing circuit 3. A stop instruction signal based on the control signal is sent to the absentee response recording section 6 to stop the operation of the absentee response recording section 6. As a result, busy tones are recorded on the magnetic tape in a predetermined time width. At this time, the busy tone detection section 15 sends data indicating the presence of a busy tone to the storage section 17 via the control section IO. As a result, data indicating one busy tone is stored in the storage unit 17.

In this way, each time there is an incoming call, message messages M1, M2, and M2 are sent as shown in FIG. M3... and busy tone BL
, B2. B3... are recorded in the order of arrival, and the business messages Ml, M2. M3... will be recorded with a time width that corresponds to the length of the message from the other party (see Figure 3).

After this, when the user of the answering machine returns home and presses the playback switch 7 in an attempt to listen to the message recorded while he was away, the switch detection unit 16 sends a signal instructing to play only the message. Part 10 is given. Upon receiving this instruction signal, the control unit 10 reads out the count data of the business message from the storage unit 17, and
A control signal instructing reproduction of the portion of the magnetic tape corresponding to this count data is sent to the absence response control section 13. Based on this control signal, the absence response control section 13 sequentially sends to the absence response recording section 6 an instruction signal including a start value and an end value for rewinding the magnetic tape and reproducing only the business message. As a result, the playback and stop of the magnetic tape of the answer recording unit 6 is controlled based on the count data, and the message messages M1, M2, . M3... are played in sequence. This reproduction signal is supplied to a speaker (not shown), so that the user can listen to a plurality of messages in which only the business message is reproduced. This greatly reduces message listening time.

Furthermore, with the present invention, even if the message from the other party is short and lasts for example 2 to 3 seconds, it is recorded as a business message and can be heard in its entirety when it is played back. If the voice of the other party is the same, it is easy to identify the other party.

Note that during playback, if you operate the playback switch 8,
Since all messages are played back, you can know the number of incoming calls including busy tones.

(Effects of the Invention) In the answering machine of the present invention, when a business message is sent from the other party, the count value counted as the business message is stored in the storage unit as count data, and a busy tone is sent. When the message comes, the detection signal is stored in the storage unit as one of the messages, and at the time of playback, by operating the message playback operation unit, only the message with the message is played based on the count data stored in the storage unit. Since it is constructed so that it can be reproduced, the listening time can be shortened by the time when the busy tone is not reproduced.
