Abstract

PURPOSE:To allow one automatic answering function to make automatic answering for all extension telephone sets by implementing automatic answering recording so as to combine a dial-in function and an automatic answering function set in the case of an extension telephone set receiving a call set to the automatic answering mode. CONSTITUTION:A switch control section 11p compares an extension number sent from a PB signal detection section 11i with an extension number stored in a memory section 11l. When the extension numbers are coincident, the switch control section 11p sends a control signal to a reply message control section 11k. The reply message control section 11k reads a reply message A1 of an address (q) corresponding to an extension number '1234' by using the control signal and sends it. The reply message A1 is sent to a telephone line via a speech network 6, terminals e, f of a changeover switch 3, a line closing circuit 2 and a tip rind 1.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an answering machine having a dial-in function and connected to a plurality of extension telephones. The present invention relates to an answering machine that automatically records an answering machine when the telephone is in an answering machine mode.

(Prior Art) In a conventional answering machine having a dial-in function and connected to a plurality of extension telephones, in order to have an answering machine function, the extension telephone itself had to be used as an answering machine. In other words, in order to have all connected extension telephones respond to answering calls, it was necessary to set all extension telephones to answering machines.

(Problems to be Solved by the Invention) Therefore, for example, when four extension telephones are connected to one line by dial-in, four answering machines are required, resulting in high costs.

The present invention was made in view of the above circumstances, and its purpose is to combine the dial-in function and the answering function to make it possible to answer the answering calls for all extension telephones using the answering function of one unit. The purpose of the present invention is to provide an answering machine.

(Means for Solving the Problems) In order to solve the above problems, the answering machine of the present invention has the following features:
An answering machine having a dial-in function and connected to a plurality of extension telephones, comprising an extension number identification means for identifying each extension number of the plurality of extension telephones, and an extension number by the extension number identification means. A switching means connects to the extension telephone corresponding to the extension number sent from the telephone line based on the identification of a response message sending means for sending a response message corresponding to an incoming call to the extension number when the extension number is set to answering; and message recording means for recording a message from the other party.

In addition, the recording area of the message recording means is divided into a plurality of small recording areas corresponding to the number of extension telephones, and when an arbitrary extension number is set to answering, the message recording means will not respond to incoming calls to that extension number. The system is configured to record the other party's message in the corresponding small recording area.

(Operation) When a certain extension number is set to be away, this extension number is identified by the extension number identification means.

When an incoming call is received to the extension number set as an answering service, the response message sending unit sends the response message stored in correspondence with this extension number to the telephone line. At the same time, the message recording means is
Record the business message from the other party who responded to the sending of the response message.

In addition, the recording area of the message recording means is divided into a plurality of small recording areas corresponding to the number of extension telephones, and when an arbitrary extension number is set to answering, the message recording means will not respond to incoming calls to that extension number. Record the other party's message in the corresponding small recording area. Thereby, it is possible to collectively record for each extension number, and also to reproduce collectively for each extension number.

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

1j, the response message control section 11 includes a memory section 112 consisting of a RAM, etc., and a switch control section 11.
m, a key reading section 11n, and a switch control section lip. The switch control unit 11p receives the output of the incoming call detection unit 11g which receives an incoming call detection signal from the incoming call detection circuit 5 and outputs detection data, and the output of the incoming call detection unit 11g which receives an incoming call detection signal from the PB signal detection circuit 9 and outputs detection data. The output of the PB signal detecting section 11i, which performs the operation, and the output of the key reading section 11n, which receives the key human power signal from the key human power section 10 and outputs detection data, are led. Further, from the switch control unit 11P, a line closing unit 11h that sends a switching signal to the line closing circuit 2, a message recording control unit 11j that sends an operation signal to the message recording circuit 8, and a response message sending circuit. A control signal is sent to a response message control section 11 that sends a drive signal to the switch 7, and a switch control section 11m that sends a switching signal to the switching control input of the changeover switch 3. In addition, the memory section 11
42 and the switch control unit lip are bidirectionally connected.

In the above configuration, the response message sending circuit 7 is connected to each extension telephone A as shown in FIG.
,B,C,D dedicated response message At,B

are stored in correspondence with Further, the recording area of the message recording circuit 8 is as shown in FIG.
,C.

Four small recording areas A2. B2. C2D2, and each extension telephone A, B, C, D has a corresponding small recording area A2. B2. They are recorded together on C2 and D2.

Next, the operation of the answering machine having the above configuration will be explained. However, the response message sending circuit 7 includes each extension telephone A.
It is assumed that dedicated response message data corresponding to -D has already been stored.

Further, the telephone number for the extension telephone is "N234", and the telephone number for extension telephone B is "r5678".

Assume that the key operator 10 is operated to set extension telephone A to answering machine mode. The operation of the key manual section 10 at this time is read by the key reading section 11n and is given to the switch control section lip. The switch control unit zp is
With this input signal, it is stored in the memory unit 111 that the extension number "N234" is in the answering mode.

In this state, when an incoming call is received from the other party's telephone through the telephone line, an incoming call signal is input through the tip ring 1 and detected by the incoming call detection circuit 5. Then, after being converted into a pulse signal, it is given to the incoming call detection section 11g. The incoming call detection section 11g counts the input pulses, and when the set number of pulses is counted, the incoming call detection signal is input to the switch control section lip. In the switch control unit lip, based on this incoming call detection signal, the line closing unit 1
A control signal is sent at 1h. The line closing unit 11h controls the line closing circuit 2 using this control signal to close the telephone line. After that, when the extension number ``1234J'' is sent from the exchange (not shown), this extension number is sent to the PB signal via the tip ring 1, the line closing circuit 2, the terminals fe of the changeover switch, and the speech network 6. Detection circuit 9
Here, after being converted into a digital signal, it is provided to the PB signal detection section 11i of the system control circuit 11. In the PB signal detection unit 11i, the received extension number r
1234'' and sends it to the switch control unit lip. The switch control unit lip compares the extension number sent from the PB signal detection unit 11i with the extension number stored in the memory unit 11f. When the extension numbers match, the switch controller lip sends a control signal to the response message controller 11k. In response to this control signal, the response message control unit 11 reads and sends the response message A1 at the address q corresponding to the extension number r1234J. This response message AI is sent from the speech network 6 to the terminal e- of the changeover switch 3.
f, is sent to the telephone line via the line closing circuit 2 and the tip ring 1.

Next, the switch control section lip of the system control circuit 11 sends a control signal to the business recording control section 11j. The message recording control unit 11j controls the message recording circuit 8 using this control signal, and records data at the start address U of the small recording area A2 corresponding to the extension number "1234" among the recording areas of the message recording circuit 8. , record the message (1) sent to you.

In this way, when extension telephone A is set to answering machine mode and a call is received to the telephone number of extension telephone A, a response message is sent each time the call is received, and the other party who answers the call receives a response message. The speaker's message is recorded in the small recording area A2 of the message recording circuit 8 as message message (1).
, Message (2), etc. are recorded in sequence. Furthermore, this kind of recording is the same even when the other extension telephones B and CD are in answering machine mode.

On the other hand, when another call is received from the other party's telephone through the telephone line, an incoming signal is manually inputted via the tip ring 1 and detected by the incoming call detection circuit 5.

Then, after being converted into a pulse signal, it is given to the incoming call detection section 11g. The incoming call detection unit 11g counts these input pulses and counts the set number of times.
The incoming call detection signal is input to the switch control section 11p. The switch control section 11p sends a control signal to the line closing section 11h based on this incoming call detection signal. Line closing section 11
h controls the line closing circuit 2 using this control signal to close the telephone line. After this, when the extension number '5678J is sent from the exchange (not shown), this extension number becomes
It is applied to the PB signal detection circuit 9 via the tip ring 1, the line connection circuit 2, the terminals fe of the changeover switch, and the speech network 6, where it is converted into a digital signal, and then the PB signal of the system control circuit 11 is sent to the PB signal detection circuit 9. The signal is given to the signal detection section 11i.

In the PB signal detection unit 11i, the received extension number r5
678'' and sends it to the switch control unit lip.

The switch control section 11p compares the extension number "5678" sent from the PB signal detection section 11i with the extension number "1234" stored in the memory section 11f.

In this case, since extension number '5678J is not set to answering mode, the switch control section 11P sends a control signal to the switch control section 11m. Based on this control signal, the switch control section 11m sends a switching signal to the switching control input of the changeover switch 3, and connects the movable terminal f of the changeover switch 3 to the fixed terminal. As a result, extension telephone B and the other party's telephone are connected.

(Effects of the Invention) According to the answering machine of the present invention, an answering function can be used to answer each of a plurality of connected extension telephones. Furthermore, since the extension telephone may be a regular telephone, it is possible to reduce the cost of the entire device.
