JPS6115452A - Automatic recording system in one's absence - Google Patents

Abstract

PURPOSE:To allow a called person to recognize clearly the name of a caller when the called person comes back the seat by providing a transmitter transmitting information such as an own telephone number to a caller telephone set. CONSTITUTION:When an incoming call comes while the called person leaves its seat, a reception processing section CPUb drives a voice memory MEMb to inform the absence of the called person to a caller. When the caller hooks on, a caller side processing section CPUa reads the data such as the own telephone number from a dial memory section MEMa to activate a sending section SEND and transmits the data to the called person. The caller person demodulates the signal by using a tone demodulation section TONE and supplies an output to an output section OUT such as a display or a printer. In such a case, the time represented by a watch WATCH is outputted at the same time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an accessory device for a telephone, and particularly relates to a system for recording a caller's telephone number, etc. when making a call when the telephone is away.

[Conventional technology]

Traditionally, answering machines have been used as a way to handle calls that come in when you are away.

Answering machines are widely used because they have a built-in tape device that answers the call, announces your absence, and records messages from the caller.

[Problem that the invention seeks to solve]

With conventional answering machines, if the caller learns from the tape device that the called party is not available and hangs up without leaving a message, the called party will know that the call came while he was away. However, there was a drawback that it was impossible to tell who was calling.

[Means for solving problems]

The means for solving the problem consists of a storage device for information such as the calling party's telephone number, an activation switch, and a mechanism for transmitting the stored contents of the storage device using a touch tone signal. a device output circuit for transmitting a call, a mechanism for transmitting an audio signal indicating the absence of the called party;
and a receiving device consisting of a mechanism, etc. that detects information such as the telephone number from the touch tone signal, and the calling party's telephone sends a ring tone to the called party's telephone when the party is absent via the exchange. In this case, the receiving device detects the ringing tone, closes the office line, and sends an audio signal indicating the called party's absence, and the calling party operates the activation switch after hearing the audio signal. By doing so, information such as the calling party's telephone number is sent to the called party via a push-tone signal over the central office line, and the called party receives the push-tone signal and transmits the calling party's telephone number, etc. This is achieved by an absentee recording system that detects the information, memorizes and displays it, and then opens the office line.

[Effect]

According to the present invention, as described in the section of means for solving the problem, when the calling party calls the called party and hears an audio signal indicating that the called party is absent, the activation switch 7 is activated. It has the advantage of being able to tell the called party the time and who made the call by just pressing the button.

〔Example〕

FIG. 1 is a block diagram showing an embodiment of the absence record system according to the present invention.

In the figure, TELa is a calling telephone, SW is a hook switch,
SEND is a push-tone transmitter, NCUa is a transmitter line interface, IN is an input ink face,
M E M a is part of the dial memory, CPUa is the calling side processing unit, LINE is the line, TELb is the called telephone, N
CUb is the ink face section for the receiving side line, TONE is the tone demodulation section, OUT is the output section for display and printer, etc.
EMb is an audio memory, WATCH is a clock, and CPUb is a receiving side processing unit.

The details of the present invention will be explained below with reference to the drawings.

When the calling party picks up the handset of the calling telephone TELa, the line LINE is closed, and the calling party calls the called party by dialing. switch(
(not shown) receives a dialing signal and sends out a ringing tone to a predetermined called party.When the called party is absent, the device is activated before leaving the seat. Suppose that a ring tone is sent to you while you are absent.

On the called party's side, the receiving side line interface unit NCUb detects the ringing tone, and the receiving side processing unit cpub receives this detection signal and closes the line LINE. Next, the receiving side processing unit CPUb drives the voice memo lJMEMb and sends a message informing that the called party is absent to the calling party via the receiving side line interface unit NCUb.

The caller hears this message and presses the hook switch SW.
, the input interface section IN detects this and notifies it to the originating side processing section CPUa.

The calling side processing unit CP'Ua receives this signal, reads data such as its own telephone number from the dial memory part MEMa, operates the touch tone sending unit SEND, and sends it to the called party side. After the sending is completed, the sending side processing unit CPUa
opens the track LINE.

On the called party's side, the signal is received via the receiving side line interface unit NCUb, demodulated by the tone demodulator TONE, and output to an output unit OUT such as a display or a printer.

The time indicated by the clock WATCH is also output at the same time. After the above operation is completed, the receiving side processing unit CPUb sends a signal to the receiving side line interface unit NCUb to open the line LINE.

FIG. 2 is a schematic diagram showing another embodiment according to the present invention.

The difference between FIG. 2 and FIG. 1 is that the input interface section I
By providing a keyboard input section KB in place of M. 5END is sent to the called party.

The called party side receives this information, and the receiving side processing unit CPUb
This information is restored and output to an output unit OUT such as a display or printer.

〔Effect of the invention〕

As explained in detail above, according to the present invention, when the called party returns to his or her seat, it is obvious at a glance who called and at what time, so the call can be made immediately, reducing the burden on the calling party. There is a big effect of not having to use it.
