Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a remote recording control system for an answering machine configured to allow remote control.

(Prior art and its problems) This type of answering machine is attached to a telephone set, and is configured so that the user of the telephone can control the answering machine by remote control. However, the purpose of remote control in conventional answering machines is to determine whether or not a call is received from a third party other than the user while the user is away, and how the content of the call is recorded when the call is received. The purpose of this is to listen to and play back the recorded content using remote control in order to confirm whether the content is correct or not. In this way, when the recorded content is played back and listened to by remote control, the remote control signal is not recorded.

However, one of the users of the telephone records some message on the answering machine using remote control, and attempts to transmit the message to other users by remote control playback. In this case, since the remote control signal is also recorded at the same time as the recording of the business, the reproduced remote control signal may be confused with a new remote control signal from the outside, resulting in control malfunction.

(Objective and Features of the Invention) The present invention is to prevent a remote control signal during the recording operation from causing a malfunction in the subsequent control of the answering machine even if a message is recorded on the answering machine by remote control. This provides a remote recording control system that allows for

To achieve this objective, the remote recording control method of the present invention
a remote control recording/playback means that shifts to a remote control mode in response to a remote control start signal, performs recording or playback designated by the transmitted control signal, and stops the recording or playback operation in response to a remote control end signal; rewinding means for rewinding the recording tape by at least a predetermined length of time that exceeds the reception period of the remote control termination signal when the remote control termination signal is received; The present invention is characterized by comprising an erasing means for performing silent recording in the forward direction for a length of time and erasing the recording of the remote control end signal from the tape of the recording.

(Structure and operation of the invention) The present invention will be explained in detail below with reference to the drawings.

First, a recording area allocation format in one example of the recording tape used in the present invention will be explained. FIG. 1 shows an example of this recording area allocation, and one of the features is that the recording area is sequentially divided into a large number of blocks on the recording tape 1 as shown in the figure, and furthermore, Another feature is that a response area AM for recording response messages and message areas G and S for recording message messages are allocated to one recording tape. The response area is located at an intermediate position between the start end ST and the end end ED of the recording tape, and consists of a response recorded message block AM and a response-only message block AMb. The response-only message block AMb is a recording block that records a response-only message (for example, "We are closed today,""I am out of the office," etc.) that does not involve recording the business.
For example, a time length of 60 seconds is assigned. The response recording message block AM is for recording a response message with a recording of the message (for example, "I'm not home right now. I'll record your message, so please speak when the beep sounds. Please go ahead.") A recording block to record,
For example, a time length of <60 seconds, which is the same as AM, is assigned. After the response area static, the -i task area G is sequentially arranged in each block GI+GZ'-'l GIO as shown in the figure, with a recording gap of 6 seconds between blocks, for example, with a time length of 40 seconds.

In this case, recording is performed using a microphone at the desired recording block Sl, 5 of the device.
2. This can be done by directly sending a message to S3 or s4, or it can be accessed by remote control using a PIN number etc. after connection from the subscriber line, and the predetermined recording blocks S,, S, etc. can be recorded.

Message recording can be performed on Ss or S4. Recording block S1. S2. The time lengths of Ss and S4 are, for example, general recording blocks G, G2.・-G. <40 seconds, which is the same as the time length of .

The recording tape 1 is stopped so that the first standby point Pl corresponding to the head of the response recording message block AM of the normal response area AM faces the head, and when a call is received, the message of the response recording message block AM is recorded. After playing and sending out, recording blocks G+, Gz, -G+ of general business area G
Oppose the empty block that is the first among +, and record the message at the time of the incoming call on that empty block. With a similar operation,
When messages have been recorded in all of the recording blocks G1゜G2+ ・-'+ G I O, the second message block corresponding to the beginning of the response-only message block AM is
The recording tape 1 is stopped so that the head faces the standby point P2, and control is performed so that a response-only message is reproduced and sent in response to an incoming call. The recording block Sl, -54 in the specific message area S can be accessed when controlled by the control button or by remote control using a PIN code when receiving a call, and records the specific message message or the recorded content. is controlled so that it can be played.
