JPH02193443A - Absence termination recording telephone set - Google Patents

Abstract

PURPOSE:To enable a subscriber to confirm an incoming call in absence by a voice, for example, after coming home by adding an incoming tone detecting circuit, an incoming time memory circuit, its control circuit, and a voice synthesizing circuit to a telephone set with a received speech reinforcing function, storing incoming time information when there is the incoming call, and voicing its contents later. CONSTITUTION:When an incoming ringing tone is received between line terminals, a tone ringer 8 sounds and an incoming detecting circuit 10 operates at the same time. Then the incoming time control circuit 14 writes the incoming time information in a memory circuit 13 according to the output of a synchronous detecting circuit 11. When the subscriber comes home, the incoming time control circuit 14 operates with an SKEY17 depressed to operate a received speech reinforcing circuit 5 through a state control circuit 5 and also output the number of incoming calls first from a speaker 9 through the voice synthesizing circuit 15 and then voice the time and length of the calls by a voice from the oldest call.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an absent call termination system in a telephone equipped with a reception amplification function that allows the user to confirm the other party's response voice through a speaker.

(Prior Art) Efforts have been made to make telephones multi-functional, and a telephone called 'iP'i' has been put into practical use as a telephone which has the function of answering calls when a person is absent.

Conventional answering machines have the added function of sending a message when a missed call is received, after answering the call, and recording the voice of several callers.

(Problems to be Solved by the Invention) Conventional answering machines always operate after incoming calls are answered, making it impossible to check the number of incoming calls, time, etc. without answering them. Ta.

The purpose of the present invention is to provide a missed call recording telephone that records the number of incoming calls and the time of each incoming call without answering and connecting, so that the contents can be confirmed later by voice. be.

(Means for Solving Problem ff1) To achieve the above object, the missed call recording telephone according to the present invention connects a series circuit of a dial sending circuit and a talking circuit between a pair of line terminals.

Detecting a ring tone in a telephone set in which a receiving loudspeaker circuit is connected in parallel to the talking circuit, and a state control circuit controls the dial sending circuit, the talking circuit, and the receiving loudspeaker circuit so that the receiving loudspeaker can be amplified in addition to one call. a synchronous detection circuit for determining an intermittent ringtone outputted from the ringtone detection circuit as an incoming call; a timer circuit for outputting a 1 time signal; and a number of 1 call indicated as the latest write address; a memory circuit for storing an incoming call time and a ringing time; a speech synthesis circuit for converting the contents of the memory circuit into audio and inputting the audio output to the receiving loudspeaker circuit; and when the synchronization detection circuit determines an incoming call; Incoming call time information is stored in the memory circuit by referring to the time signal of the timer circuit, and when a predetermined operation is performed, the contents of the memory circuit are read and the latest write address, the time of each incoming call, and its ringing time are stored. and an incoming call time control circuit that sends the data to the speech synthesis circuit.

(lol example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a missed call recording telephone according to the present invention.

A dial sending circuit 3 and a talking circuit 4 are connected in series between line terminals 1 and 2, and a power supply circuit 7 and a tone ringer 8 are connected in parallel to this series circuit. and call circuit 4
A receiving loudspeaker circuit 5 is connected in parallel to. The state control circuit 6 controls the dial output path 3, the speech circuit 4p, and the loudspeaker circuit 5, respectively.

The configuration up to this point is the conventional reception amplification@#lf of the functional telephone.
In addition to this, the line terminal l.

A ringtone detection circuit 10 is connected between 2 and 2, and a synchronization detection circuit 11 is connected to the output of the ringtone detection circuit 1 (which obtains the output of 1 and outputs a valid signal only at 9 o'clock) every 3 seconds. ,
A timer 12 that counts the time, and a memory circuit 13 that stores the number and time of missed calls. The time of the timer 12 is input to the memory circuit 13 according to the outputs of the speech synthesis circuit 15, which converts memory circuit data into speech, and the synchronization detection circuit 11. r13 data t-speech synthesis circuit 1
An incoming time control circuit 14. Reset K
EY, 1 (consists of 16 KBY and 8 KBY to start calling absent data).

Synchronization detection circuit 11. Timer 12, KEY16 and 8
Each output of KBY17 is sent to the SD of the incoming time control circuit 14.
, T, RK, and SK large inputs are connected to each other. Further, the control output 0 of the 1-incoming call arrival time control circuit 14 is the state control circuit 6.
The data output O is connected to the voice synthesis picture *15, and the output of the voice synthesis circuit 15 is connected to the input of the loudspeaker circuit 6, respectively.

In the telephone according to the present invention, when an incoming ringing tone is received between the line terminals, the tone ringer 8 sounds and the incoming call detection circuit 10 operates, and the logic output (ringing tone present high level "H") is activated.
, silent low level "shi") and synchronization detection circuit 11
Output to. The synchronization detection circuit 11 checks whether or not the rHJ level is input every 3 seconds after the first rHJ input, and if it occurs two or more times in a row, it is assumed that there is an -acceptance call and the output is set to rL.
Continuous output from J to rHJ. Incoming call time control circuit 14
is synchronization detection time I! Based on the output of 611, the incoming call time information is written into the memory circuit 13. In other words, the synchronization detection circuit 'R1r
When receiving the rHJ output from timer 11, the time signal from timer 12 is written into memory circuit 13, and there are no more incoming calls.

When the output of the synchronous machine output %11 becomes "L", the time is written into the memory circuit 13 and one process is completed. In the same way, the absent nursing call information is written nine times in succession. By referring to the latest written address, the total number of calls can also be determined.

To check when you return home, press the %8 key 17 to activate the incoming call time control circuit 14, which activates the reception amplification circuit 5 through the state control circuit 6, and outputs the number of incoming calls from the speaker 9 through the voice synthesis circuit 15. Now then, next time.
From the 11th oldest 10,000, output the time and length t-voice.

If you want to stop midway, press the 5KEY17 as well to stop the reading and turn off the loudspeaker circuit 5. In addition, to erase all contents, press RKBY16i to reset the contents of memory times\Ir13.

With conventional answering machines, incoming calls were answered and a charge was always made, which in some cases caused discomfort to the caller. In this system, the caller is unknown, but by arrangements such as 3-minute delayed calling, incoming calls from several people can be identified. You can check.

(Effects of the Invention) As described above, the present invention adds a ring tone detection circuit, an incoming call time memory circuit, its control circuit, and a voice synthesis circuit to a conventional telephone with a loudspeaker function, and when an incoming call is received, It is configured so that it can determine whether the call is an incoming call, store the incoming time information such as the time and the time it was ringing, and output the contents as voice later. This has the advantage of being able to confirm the time and number of incoming calls, for example, by voice when returning home.
