Abstract

PURPOSE:To perform an automatic call while responding to a call from a line wire by performing private broadcasting for the automatic call according to voice information that a line wire telephone is recorded. CONSTITUTION:When a telephone call through the line wire arrives during an automatic call mode after setting a mode setting switch 18 at an automatic call mode, an incoming detection circuit 12 detects it and outputs a detection signal (b). A CPU 17 receiving it makes a current flow in a coil L12, and turns a switch SW into a conductive state. Subsequently, it supplies prescribed control data and address data to a voice synthesis IC circuit 16 and from lines L0, L1 a voice guide message (c) from the voice synthesis IC circuit 16 is returned to a caller through an automatic calling line 13. When the caller responding to this message returns prescribed callee information (d), the information (d) is recorded in a voice memory means 23 through a voice recording/reproduction IC circuit 14. Afterward, the voice recording/reproduction IC circuit 14 reads out the information recorded in the memory means 23 and supplies it to a private broadcasting equipment 15 so as to call the callee by a voice of the caller.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an automatic calling telephone device, and in particular, to an automatic calling telephone device that is capable of automatically calling even calls from outside lines.

(Prior art) When a call is received, the name of the other party is automatically called out even if no one picks up the phone. When a call is made, a system is adopted in which the caller's voice is used to call out the other party's name through a speaker. However, it was not used for calls made through telephone stations using outside lines.

That is, 1. For example, in Japanese Utility Model Application Publication No. 62-86761,
Some systems have an automatic calling function by branching broadcasting lines and monitor speaker lines to an extension telephone system installed in one premises, but such automatic calling systems cannot answer calls that come in through an outside line. It wasn't something to do.

(Problems to be Solved by the Invention) Conventional telephone devices do not have the added function of automatically calling calls made through an outside line.

The object of the present invention is to eliminate the above-mentioned problems and provide an automatic calling telephone device that makes a call in response to an outside telephone.

[Structure of the Invention] (Means for Solving the Problems) The present invention provides an automatic calling telephone device that is connected to a telephone line and automatically calls a called party when an outside call arrives. The audio guide will be sent to the line,
This system is equipped with automatic calling circuit means for receiving and recording called party information from a calling party and for making a public announcement based on the recorded called party information.

(Function) According to the present invention, since a local announcement for automatic calling is performed based on voice information recorded from an outside telephone, messages from callers can be regulated and calls caused by mischief can be prevented.

(Example) The present invention will be explained below with reference to illustrated embodiments.

FIG. 1 is a block diagram showing an embodiment of an automatic calling telephone device according to the present invention. In the figure, reference numeral 11°10 is a telephone line, to which a telephone l110 is connected, and one line L1 is connected to a line monitoring circuit 11 that monitors the call status by, for example, DC voltage when the line is connected. . An incoming call detection circuit 12 is connected to the telephone ports 5aLO and L1, as well as an automatic calling line $113 according to the present invention.

Therefore, the automatic calling line 13 is connected to the switch SW.

Transformer top 11. Coil L12 that drives switch SW
The switch SW is connected between the primary winding of the transformer L11 and the telephone lines LO and Ll.
The secondary winding of ll is connected to the audio recording/reproducing IC circuit 14, the public address system 15. It is connected to an automatic calling circuit (see dotted line) consisting of a voice synthesis IC circuit 16 and the like.

The automatic calling circuit inputs the caller's voice signal from the transformer L11 to the voice recording/reproducing IC circuit 14, and records the voice signal in the voice memory means 23 connected to the circuit 14.

The recorded audio signal is played back and amplified via a public address system 15.

The voice synthesis IC circuit 16 is a circuit that sends a predetermined voice guide to the caller, and its voice output is sent to the amplifier AM.
1 to the transformer L11.

On the other hand, 17 is a microprocessor (called CPLI),
A microcomputer circuit consisting of a working memory (hereinafter referred to as RAM) and a program memory (hereinafter referred to as ROM), each CPU and RAM.

The ROM is connected to input/output (Ilo) ports 19, 20, 2 via a control bus, data bus, and address bus, respectively.
1.22 and is connected in a predetermined state.

Here, the I10 port 19 is the output 1 of the line monitoring circuit 11.
The output of the incoming call detection circuit 12 and the output of the automatic call mode setting switch 18 are respectively input, and each of these input information is led out to the data bus. The I10 boat 20 is a circuit that drives the coil L12 via the amplifier AM2 to turn on the switch SW when the I10 boat 20 is set to automatic calling mode and data indicating incoming call detection is input from the I10 boat 19. I10 boat 21 is a voice synthesis IC circuit 16
It supplies various data for driving the speech synthesis IC circuit 1B.

Further, the I10 port 22 is a circuit that supplies various data for driving the audio recording/reproducing IC circuit 14 to the same circuit 14. As a result, the CPUs monitor the status of each line, and the voice synthesis IC circuits 16. The voice recording/reproducing IC circuit 14 and automatic calling line 13 are controlled.

The present embodiment is constructed as described above, and its operation will now be described with reference to FIG.

When the mode setting switch 18 is set to the state shown in FIG. 1 and a high level signal is input to the I10 port 19, the telephone device enters the automatic call mode. This operating mode will hereinafter be referred to as the initial mode, and is performed in step S1 in FIG.

When a call is received through an outside line during the initial mode, the incoming call detection circuit 12 detects a ringing signal a for ringing the telephone 10. A detection signal resulting from this is sent to the I10 boat 19. CPtJ inputs the data based on the above signal to the I10 port, and also inputs the data based on the above signal to the line monitoring circuit 1.
1, and if there is no call after a predetermined period of time, step S3 is performed to flow current through the coil L12 via the I10 boat 20 and turn the switch SW into a conductive state ( automatic ringing line connection). Next, predetermined control data and address data are sent to the voice synthesis IC.
The signal is supplied to the circuit 16 and step S4 is executed.

As a result, the voice guide message C from the voice synthesis IC circuit 16 is transmitted from the lines LO and L1 to the automatic calling line 1.
3 to the caller.

The calling party responds to the above message and sends the specified called party information d.
, this information d is sent to the voice recording/reproducing I by the CPU.
By driving the C circuit 14, the audio memory means 2
3 (see step S5). Thereafter, the audio recording/reproducing IC circuit 14 reads out the information recorded in the memory means 23 and supplies it to the local public address system 1fi15. As a result, the public address system 15 performs a broadcast to call the called party using the voice of the caller in step S7. During this broadcast, the CPU puts the line in hold mode in step S6. Although the voice memory means 23 is not necessary when the caller's voice is directly used as the broadcast sound, the voice memory means 23 is provided in order to perform repeated broadcasts.

In step S8, it is determined whether the telephone 10 is off-hook. That is, when the handset is off-hook, the line monitoring circuit 11 detects the DC voltage, so it is determined that a conversation has taken place between the calling party and the called party (YES), and the CP
U returns to the initial mode in step S9. If (NO) in step S8, step 810 is performed.

Step 810 is a timer operation, which sets a waiting time for repeating the determination in step S8 until the called party answers the phone.

If the called party does not answer the phone even after this time has elapsed, it is determined that the time has elapsed (Y[S) L.

Then step 311 is performed. In step S11, the voice synthesis IC circuit 16 informs the caller of the absence of the called party.

Sends the message to an outside line. Thereafter, the CPU returns to the initial mode (step 512).

In this embodiment, as described above, even if there is no telephone manager, it is possible to answer a telephone call from an outside line and automatically call the called party.

In the case of a wrong call, there is a risk that the voice guide will be used as a prank and a prank broadcast will be broadcast, so the caller's voice should be registered, messages sent by the voice guide should be restricted, and the caller should be able to control the number of messages sent by the voice guide. Only the name of the person and the name of the called party may be recorded in the voice memory means 23.

In addition, at night, etc., a voice guide will be used to send a message that the call service will not be available at night.
A printer may be connected to the voice recording/reproducing IC circuit 14 to print out messages when the user is absent. The latter method of printing out can also be applied when the called party is absent.

[Effects of the Invention] As explained above, according to the present invention, an automatic call can be made in response to a telephone call from an outside line.
