Abstract

PURPOSE:To grasp the outline of an input message and discriminate the value of the message in a short time by using a tape and an IC memory, recording a head of the opposite input message and reproducing it during tape rewinding. CONSTITUTION:A control signal is given to an IC memory recording circuit 12 and a recording/reproducing head 10 to bring them in the standby state, and when an input message from the opposite party in succession to a reply message and a signaling tone exists, they are operated and the content is recorded simultaneously in the IC memory 11 and on the tape. In this case, the head of the input message is recorded in the IC memory 11. The input message recorded on the tape and in the IC memory 11 is reproduced by a reproduction command, but the input message recorded in the IC memory 11 is implemented during tape rewinding with priority. Thus, the outline of an input message is grasped and the value of the message is discriminated in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an answering machine for recording/playing messages from the other party.

(Prior Art) Generally, an answering machine is equipped with a tape for recording messages from the other party, and when it detects an incoming call, it sends out a response message, switches to recording mode, and records the input message from the other party on the tape. It has become. When a reproduction command is received, the tape is rewound and the recorded message of the other party is reproduced.

FIG. 6 is a timing chart showing the operation of a conventional answering machine. When an incoming call from the other party is detected by bell signal detection, an answering message (OGM) is sent out, and then a signal sound A is emitted and the machine enters recording mode. Following this signal sound A, the tape records input messages sent from the other party in the order in which they were received.

The recorded input message is played back by inputting a playback command to the answering machine. When the answering machine receives the reproduction command, it rewinds the recording tape and then reproduces the first input message in order.

(Problem to be Solved by the Invention) This type of answering machine plays back the entire contents of the recorded input message, so the recipient cannot understand the contents unless they listen to all the messages from the beginning. , it takes a long time to sort out that information. In addition, when the owner performs playback by remote control over a telephone line from outside the home, the call state continues for a long time from the time the tape is rewound until the end of tape playback, and the call state is 9jj.

Not only will it be impossible to receive other calls, but call charges will also be added.

On the other hand, instead of such tape recording, answering machines are used that use IC memory as a recording medium, which does not require rewinding.In this case, the recording time is short and long-term recording is not possible. .

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an answering machine that can confirm messages input by the other party in a short period of time and can also record messages for a long period of time.

[Structure of the invention]

(Means for Solving the Problems) The present invention uses both a tape and an IC memory as recording media, and records the first part of an input message on the IC memory. After answering an incoming call, the answering machine according to the present invention switches to the recording mode, records the input message from the other party on a tape, and, after receiving a predetermined playback command and rewinds the tape, records the input message. An answering machine configured to play back a message, an IC memory capable of recording the input message, and a means for recording a message manually inputted by the other party into the IC memory within a predetermined time after switching to a recording mode. , means for reproducing the input message recorded in the IC memory before tape rewinding is completed upon receiving a reproduction command.

--F-- In addition to the above-described configuration, the embodiment of the present invention is also provided with means for recording a time message informing the arrival time in the IC memory.

(Function) The input message of the other party is recorded on the tape and the IC memory at the same time, or the message portion during a predetermined time from the start of recording, that is, the beginning portion of the input message is recorded on the IC memory.

These input messages recorded on the tape and IC memory are played back in response to a playback command, but the input messages recorded on the IC memory are played back preferentially while the tape is being rewound. Based on this information, it becomes possible to decide which information to choose. Further, in the embodiment, a time message indicating the time of incoming call is also recorded in the IC memory, and in this case, this time message also helps in determining the value of the information.

It has a photocoupler 42 and a transistor 43 that converts the analog bell signal detected by the photocoupler 42 into a pulse signal. and,]·
The pulse signal converted by the transistor 3 is input to the bell signal detection port of the CPU 7, and the input information is given to the bell signal information determining means 71. Bell signal discrimination means 71
Then, by inputting this bell signal, the incoming call is recognized and the incoming call information is sent to the control means 75 (FIG. 2). Based on this, the control means 75 issues a control signal to the IC memory recording circuit 12 (FIG. 1) and the recording/playback head 10 (FIG. 1) to put them in a standby state, and then responds to a response message and a signal sound. When there is a subsequent input message from the other party, these are activated to simultaneously record the contents on the IC memory 1] and tape. In this case, all the messages of the other party are recorded on the tape, but the IC memory 11 is controlled to record messages at a predetermined time from the start of recording.

Next, the operation of the above embodiment will be explained.

When the key for the answering machine is input by key operation of the key matrix, this input is recognized by the key power determining means 72 in the CPU 7, and the answering machine mode is set. When receiving an incoming call from the telephone line in this state, a response message is sent to the other party, followed by a signal tone and the device enters recording mode.

Then, following the signal sound, when a voice is input from the other party,
This input message is simultaneously recorded on IC memory 11 and tape. The input message is recorded to the IC memory 11 for a predetermined period of time from the start of recording based on the signal sound, that is, to the beginning of the input message.On the other hand, the recording to the tape is performed continuously for a predetermined recording time until the end. This is done for all input messages.

In this embodiment, a speech synthesizer 13 for outputting a time message is provided, and the time is converted into voice and outputted at the same time as a call arrives.

The output audio time passes through the preamplifier 2 from the analog switchco, and is output from the recording filter circuit 14 to the recording/playback head 10 and the IC memory recording circuit 12. The output of the voice time is controlled to be performed before the input of the message from the other party, and the output voice time is recorded on the IC memory 11 and the tape, respectively, before the input message from the other party.

FIG. 4 does not show the timing used for this audio time, but is time chart 1. After the bell signal (FIG. 4(a)) is detected by the photocoupler 42 of the bell signal detection circuit 4, the same circuit The signal is converted into a pulse signal by the transistor 43 of No. 4 (FIG. 4(b)). This pulse signal is input to the bell signal detection board of the CPU 7, and the CPU 7 detects an incoming call based on the number of pulses and the pulse +l+, and when a preset number of incoming calls of the bell signal (for example, 2 times) is detected, a response message is sent. Send it to the other party. On the other hand, the CPU 7 receives a bell signal less than the set number of calls (in this embodiment, 1
speech synthesizer based on the bell ringing signal)
3, a trigger signal ((C) in the same figure) is output. As a result, the speech synthesizer] 3 outputs the audio time ((d) in the figure). Therefore, by performing such timing control, the voice time can be recorded before the other party's message is input.

FIG. 5 is a timing chart showing the entire recording process described below, and the response message (IC memory 1) is
○GM), the first call arrival time d is recorded, and this is followed by the beginning of the first input message from the other party.

For the second and subsequent incoming calls, following the first input message, the incoming time d and the beginning part of the input message are recorded in order. On the other hand, the time of arrival and all input messages are recorded on the tape in the order of arrival. When the owner wants to check the information recorded in this way from outside the home, he or she inputs a reproduction command through a telephone line. This reproduction command is discriminated by the MF signal discriminating means 73 in the CPU 7, and the discrimination result is given to the control means 75. The first control stage 75 sends a tape rewinding command to the mechanical control circuit 6 based on the input of the reproduction command to rewind the tape. In synchronization with this, the control means 75 sends an IC memory reproduction command to the IC memory recording/reproducing circuit 2, and the IC memory 11 sequentially reproduces the recorded voice time and the beginning of the input message. That is, the voice time recorded in the IC memory 1 and the input message are played back while the tape is being rewound. Therefore, the owner can grasp the outline of the input message and decide whether to select it or not in a short time based on the playback information in the IC memory 1. Also, in addition to the other party's message,
81,! Since the information is announced every minute, it also has the advantage of helping people make informed decisions.

= ]2- [Effects of the Invention] As explained above, the present invention uses a tape and an IC memory in combination, and records the first part of the other party's input message on the IC memory. Since the playback is performed while the tape is being rewound, it is possible to grasp the outline of the input message and judge the value of the message in a short time.
