Abstract

PURPOSE:To immediately progress to the recording of requirements, by inputting a specific control signal for a person who only listens the forefront part of a response message, and does not need residual parts. CONSTITUTION:Waiting is needed until the completion of the response message in a conventional device of this type. The waiting time is long especially in a long time response message, thereby, some people is displeased with such state, and defect to increase a charge in a long distance call is pointed out. At this time, it is possible to record the requirements without listening a long response message getting tired of hearing, only by teaching a way to input such and such signal when listening the response message, for a customer who records the requirements frequently on an automatic answering telephone set. Also, it is possible to prevent the recorded message of requirements from being stolen by such customer by a remote control operation.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a remote control system in an automatic call answering device such as an answering machine that responds to an incoming call signal from a central office line, sends out a response message, and records a business message. It's about control.

(Prior art and its problems) Conventional devices of this type do not send messages such as "This is ○O, but I am not at home at the moment" after the line is closed. When it rings,
A response message such as ``please tell me your name, phone number, and business'' will be sent, and the caller will hear a beep and then record the message, so you will have to wait while listening to the response message. There wasn't. In particular, when the response message is long, the waiting time becomes long, and some callers may feel dissatisfied, and the call charges for long-distance calls also increase. It is especially painful for people who use the service every day to listen to familiar messages for a long time, and conversely, if you shorten the response message, it is difficult for first-time users to understand the point. There were also some inconveniences.

(Objective of the Invention) In order to eliminate these drawbacks, the present invention provides a method for inputting a special control signal to a person who only listens to the beginning part of a response message and does not need to listen to the entire response message. The present invention provides a remote control method for an automatic response device that allows the automatic response device to immediately start recording a message.

(Structure and operation of the invention) The invention will be described in detail below.

0 is an incoming call detection circuit.

Next, the operation of this embodiment will be explained. First, the response message is recorded. By operating the operation switch 29, the control circuit 20 starts the motor 25 to start recording the response message, and when the rotation detection circuit 27 completes the cueing of the response message. Start recording the audio signal from. The audio signal is recorded on the tape 23 via the path [microphone 10 → analog gate 15 → recording amplifier 8 - relay contact a 31 - head 21'']. This is performed by a rotation detection circuit 27 and a control circuit 20 corresponding to the above.First, before recording, the control circuit 20 rotates the motor 25 in the rewinding direction to find the beginning of the tape. , rotation detection circuit 27
Next, the control circuit 2
0, the tape 23 is fed for a certain period of time while running at a constant speed, and this point is used as the beginning of the response message, and messages are recorded thereafter. This operation is similarly performed when automatically responding to an incoming call and when waiting at the beginning of a response message.

Next, we will explain how to record a message when a call arrives. When the incoming call detection circuit 30 detects an incoming call signal from the central office line and the control circuit 20 determines that the incoming call is incoming, the relay 18 is activated. As a result, the relay contact 13 is turned on and a DC loop is formed for the line. When the line is closed, the control circuit 20 starts the motor 25 and sends out a response message from a predetermined standby position. The response message is generated by picking up the signal from the tape 23 with the head 21, and transmitting it to [relay contact a31-regenerative amplifier 9-game) 16-) lance 7-
It is sent to line terminal 1 via the route of relay contact /3]. The end of the reproduction signal of the response message is detected by the voice detection circuit 12, and the control circuit 20 operates the relay A19 and the motor 26 to start recording the message.

Here, the end of the response message can be realized by recording a control signal in advance when recording the response message. Further, the message is recorded by supplying the signal from the line terminal 1 to the tape 24 via the path [relay contact 13 -> transformer 7 - gate 14 - recording amplifier 8 - relay contact a31 -> head 22]. Ru. When the caller finishes recording the message and goes on-hook, a call termination signal (busy tone) is sent to the central office line. This signal is detected by the voice detection circuit 12, and the control circuit 20 ends the recording operation and sends the message to the relay 18. The relay A19 is restored, the response message is cued, and preparations are made for the next incoming call.

Next, the operation of remote control will be explained. During the above-mentioned automatic call response, the remote control signal receiving circuit 13 monitors the remote control signal from the line. If, for example, an MF multiplied signal of a telephone is used as a remote control signal, 13 is an MF signal receiving circuit. When a remote control signal is received, for example, if the signal is a signal for reproducing a business message, the control circuit 20 starts the motor 26, brings out the beginning end of the tape 24 on the business side, and after the beginning end comes out. The tape 24 is put into a playback state, and the business message recorded on the tape 24 is sent out to the line side. here,
The start end of the message tape 24 is detected by the rotation detection circuit 28 in the same manner as the start end of the response message tape 23 described above. Further, the final position of the business tape 24 can be determined when the number of revolutions when the start end is output matches the number of revolutions during playback operation, and the playback operation is ended at this position and the next control signal is sent. Waiting.

Here, the recording operation of the business message according to the present invention will be explained. First, in the previous explanation of remote control, it is assumed that the remote control signal is defined as follows.

(il PIN number 2) (2) Yotanabe is a 2-digit number that can be set arbitrarily by the owner of the device.
Here, it is assumed that "12" is set as an example.

(iil Replay from the beginning of the message
(value) Fast-forwarding a message for a certain period of time: En (2) 匪G
v) Rewinding the message for a certain period of time: Box (3) Open (
■) Recording the business message Duplicate ■ (Xun Recording the response message: 圓 圓 口 ■ Ending the response message: Enclose E Listening to the recorded business message or dubbing the response message by remote control) In other words, for operations such as recording and playback, the user must first input a password known only to the owner.When the device detects the password, it enters a remote control state and waits for the next operation signal.

Next, when control signals such as (ii) to Gy) are input, the device performs operations corresponding to the respective signals. For example, G
When the open (5) value of vl is input, the response message is cued, and the response message is recorded using the input signal from the line side. This operation is similar to the recording operation of the response message from the microphone described above, and the signal input is from microphone 1.
0, but via the path ``line terminal 1 - relay contact J3 -) lance 7 - gate 14'', and everything from the recording amplifier 8 onwards is the same.

Recording M's business message is necessary, for example, when listening to a customer's business from a remote location and recording instructions to a third party. It will then be recorded.

After automatically answering the incoming call, the device operates the remote control signal receiving circuit 13 to monitor the remote control signal from the line, so it is possible to identify the remote control signal by the MF multiplied signal described above. Therefore, if you first receive a password like <i), you will be in the normal remote control state for recording, playback, etc., and only if you receive a recording signal of a business message like (v), It is possible to stop sending the message without waiting for the detection of the end of the response message, immediately shift to the business recording state, and move on to recording the business message. This operation is the same as the above-mentioned operation of recording messages from the line.

FIG. 2 shows an example of the above operation.

Therefore, if you tell customers who frequently record messages on their answering machines to enter the V[[ signal when they hear a response message, they will not be able to listen to the response message they have been listening to for a long time. (The business can be recorded immediately without needing to be done. Also, it is possible to prevent such customers from eavesdropping on the business messages recorded by remote control.

(Effects of the Invention) As explained above, according to the present invention, since the remote control method is provided with a control system that only allows input, the inconvenience of not being able to record the business until after listening to a long response message can be solved. This has the advantage of improving user convenience.
