Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a telephone equipped with a recording/playback function.

(Prior art and its problems) An answering machine with a recording and playback function attached to a telephone set, which has the function of recording a message from a caller when an incoming call is received while the user is away, and playing back the recorded content at a desired time. is widely used. However, with conventional answering machines, there is a response tape that records the response message issued to the other party when a call is received, and a message recorder that records the message from the other party that comes in response to this response message. Since the tape is provided separately, two systems of recording and reproducing mechanisms are required, making the device large and uneconomical. As a solution to this drawback, a configuration has already been proposed in which a recording tape having two recording tracks is used, one recording track is used for recording the response message, and the other recording track is used for recording the business message. has been done. However, even in this latter case, since a plurality of tracks are provided, the recording/reproducing mechanism must have a complicated structure to accommodate the plurality of tracks.

Furthermore, since the recording tapes of conventional answering machines are used without any particular division within the recording area of a series of recording tapes, the importance of the recorded information is not particularly relevant when reproducing the message contents. The disadvantage is that unless you replay all of the information, you will not be able to understand the outline of the information. This is a particularly serious drawback when listening to the contents of a message by remote control from an outside line.

In addition, conventional answering machines are used only to record the message of the other party when receiving a call from an outside line, and if the answering machine has multiple owners, There are no plans to use this answering machine for communication between owners.

(Object of the Invention) In view of the above drawbacks of the prior art, the present invention records a response message and a message on a single recording track, and records a plurality of recording blocks to which the recording track is sequentially assigned. Use it by dividing it into
Furthermore, the recording block is provided with a voice message type telephone integrally formed with the telephone so as to record not only the voice input from the line but also the direct input from the microphone.

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

First, the allocation format of the recording tape recording area 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. Response area AM for recording response messages and message area G for recording message messages.
Another feature is that S is assigned to one recording tape. The response area AM is arranged at an intermediate position between the start end ST and the end ED of the recording tape, and consists of a response recorded message block AM _a and a response-only message block AM _b . The response-only message block AM _b 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, for 60 seconds. A length of time has been assigned. Answer recording message block
AM _a is a recording block that records response recording messages accompanied by recording of business matters (for example, "I am not home at the moment. I will record your business, so please speak when the beep sounds. Please go ahead."). Yes, and for example, a time length of 60 seconds is assigned like AM _b . After the response area AM, there is a general business area G for each block G ₁ , G ₂ ..., G ₁₀ , for example.
They are arranged sequentially as shown in the diagram with a recording gap of ₆ seconds between blocks with a time length _{of 40 seconds} . Record the content of the call. One of the features of the present invention is that the recording blocks S ₁ , S ₂ , S ₃ , S ₄ of the specific business area S are provided outside the recording blocks G ₁ , G ₂ , ..., G ₁₀ of the general business area G. This feature is that the recording blocks _S1 ,... _S4 of this specific message area S can store specific message messages instead of so-called "memos" for mutual communication among multiple parties using this telephone. Record. Recording in this case can be done by directly putting a message into the desired recording block S ₁ , S ₂ , S ₃ or S ₄ of the device using a microphone, or by remote control after connection from the subscriber line. Access can be made using a password or the like, and recording of a message can be performed in a predetermined recording block S ₁ , S ₂ , S ₃ or S ₄ . The time lengths of recording blocks S ₁ , S ₂ , S ₃ , S ₄ are, for example, general business recording blocks G, G ₂ ,...G ₁₀
40 seconds is selected, the same as the time length of .

The recording tape 1 is stopped so that the first special point _P1 , which corresponds to the beginning of the response recording message block AM _a of the normal response area AM, faces the head, and when a call is received, the response recording message block is stopped.
After reproducing and transmitting the message of AM _a , the receiver moves to the first blank block among the recording blocks G ₁ , G _{2 ,} . In a similar operation, when messages have been recorded in all recording blocks G ₁ , G ₂ , ..., G ₁₀ , the head is sent to the second waiting point P ₂ corresponding to the beginning of the response-only message block AM _b . Recording tape 1 so that
is stopped, and the system is controlled to play and send a response-only message in response to incoming calls. Recording blocks S ₁ ,...S ₄ in the specific message area S can be accessed when controlled by the control button or by remote control using a PIN number when receiving a call, and can be accessed to record specific message messages or Control is performed so that the recorded content can be played back.
