Abstract

PURPOSE:To receive message transfer only when a transfer receiver himself is convenient by executing automatic dialing to a transfer destination only when it comes to be a previously set time so as to execute message transfer. CONSTITUTION:A control circuit 5 which detects that the previously set timer time agrees with a present time, discriminates the recording condition of a receiving tape TP2 based on the detected result, automatically dials a previously set telephone number when the message is discriminated to have been recorded and transmits all the messages from a caller which have been recorded until then is provided. The message of the caller which have been recorded in the receiving tape TP2 is transferred only at the previously set time, and therefore a user himself can confirm the message of the caller which has been transferred only at that time. Thus, the operability for using the automatic answering telephone set itself can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an answering machine having a message transfer function.

Conventional technology A call circuit is activated by a telephone call from a caller, and a response message (OG) is sent from a response tape (08M tape).
M), once the message from the caller is recorded on the receiving tape (IOM) after sending, the function automatically dials a preset telephone number and sends out the message on the previously recorded receiving tape. A telephone answering machine having the following is known. At the destination of this answering machine, in order to listen to the recorded message, the user must lift the handset of the telephone that is emitting the incoming call signal (ringer signal) to form a communication circuit (0FF-HO).
OK status), confirm that it is a message forwarding phone, and enter the PIN number (security code) using the DTMF signal on the phone to hear and confirm the received message. be.

Conventional answering machines with this type of message forwarding function either send a normal response message urging the other party to record the message, or send out a specific signal (beep) when forwarding a message. The user listens to this response message or a specific signal, confirms that the call is a message forwarding call, enters the security code, and can listen to the recorded message on the receiving tape. Ta.

Problems to be Solved by the Invention However, with the above-mentioned conventional mobile phones, if the person who set up the message forwarding is asleep, it is extremely annoying that the call is a message forwarding call. be. In other words, with conventional answering machines, the message is forwarded after a predetermined period of time after the caller's message has been recorded on the receiving tape, so it is not always convenient for the user who wants to have the message forwarded. The problem was that it wasn't good.

Therefore, the present invention provides the following information only when setting the time for message transfer.
To provide an answering machine capable of transferring previously recorded messages from a caller.

Means for Solving the Problems In order to solve the above problems, the answering machine of the present invention has the following features:
It detects that the preset timer time matches the current time, uses this detection result to determine the recording status of the receiving tape, and automatically calls the preset telephone number when it determines that a message has been recorded. The system is characterized in that it is configured to dial and transmit all previously recorded messages from the caller.

1 Effect: With the above-described configuration, the present invention transfers the caller's message recorded on the receiving tape only at a preset time, and the user himself/herself can receive the call transferred only at that time. You can check the messages of other people. Therefore, message forwarding is eliminated in cases where message forwarding cannot be confirmed, such as when the user is asleep or out of the house, and the usability of the answering machine itself can be improved.

A handset 7 has a built-in speaker for receiving calls and a microphone for sending calls, and is connected to the speech circuit 6. Reference numeral 8 denotes an input unit having a group of keys for inputting control conditions such as mode switching and inputting a telephone number to the control circuit 6, and is used for setting answering mode and message forwarding standby state, inputting security code and forwarding telephone number, etc. This is what we do. Also, 9a
is a DTMF generator which generates a dial tone signal based on the encoded output of the control circuit 6 based on the key input at the input section 8, and sends it out to the telephone line via the speech circuit 6. On the other hand, 9b is DTMF
The receiver receives the dial tone signal input from the telephone line through the speech circuit 6 and inputs it as a constant coded signal to the control signal.

1o is a mechanism section and a response tape TP.

It has a mechanism that drives the receiving tape TP2, a mechanism that drives the receiving tape TP2, and a motor V that drives the mechanism, and both mechanisms have plungers (not shown) that directly control the running of the tape. . 11
A motor driver circuit outputs a control signal for driving the motor M of the mechanism section 10 based on a command from the control circuit 6. Reference numeral 12 denotes a reel stand rotation detection circuit, which detects the rotation of the reel stand rotated by the tape running of both tapes TP or TP2 using an on/off signal from a Hall element, etc., and inputs it to the control circuit 6. . 13 is a lensoid driver circuit, and the above tape T
This circuit drives the slide of the plunger in the mechanism section 1o described above in order to selectively drive it according to control conditions such as playback and fast forwarding of TP2, and outputs an output based on a control command from the control circuit 6. The output of this solenoid driver circuit 13 is the response/response as well as driving the plunger.
It is also input to the reception switching circuit 14, and the response tape TP,
The output of side messages and the output of messages on the receiving tape TP2 side are switched.

15 is a tape amplifier, which carries both of the tapes TP and T.
It constitutes a recording amplifier or a playback amplifier for P2, and switching between recording and playback is performed by commands from the control circuit 6, and signal input during recording and signal output during playback are performed via the speech circuit 6. .

Reference numeral 16 denotes a display whose display contents are driven by the output of the display drive circuit 17 based on the commands from the control circuit 6, and displays the number of calls stored in the control circuit 6 and the input transfer destination. In addition, in a normal state, a time display based on the output of a clock section similarly configured in the control circuit 6 is performed. Also,
Reference numeral 18 denotes a recording microphone for recording onto the response tape TP1, and its output is input to the tape amplifier 16.

Here, the control circuit 6 includes a timer means shown in FIG. 4. This timer means includes an oscillation circuit O8C including a crystal oscillator, a timer counter TM that counts the output of the oscillation circuit O8C, data input from an input port (timer setting time), and the current time from the timer counter TM. an accumulator 5CO into which data is input; and a memory R that stores timer setting time data via the accumulator 5CC.
AM, and a logical operation unit LU to which the data of the memory RAM is applied via the register and the data of the current time via the accumulator 5CC is applied, and which compares the current time and the timer setting time. The match signal from the logical operation unit LU is outputted to the output port through the latch circuit.

In this timer means, data (timer setting time) input from the input port is written and stored in the memory R5M through the accumulator 500. On the other hand, the current time is obtained by dividing the frequency of the crystal oscillation signal and inputting it to the accumulator 5CC through the timer counter TM. The comparison between the current time and the timer setting time is performed using the logical operation unit LU.
This is done using the data in the accumulator 5CC and the data in the memory RAM, and outputs it to the output port through the latch. The data inputted from the input port is data from the input section 8, and data from the key telephone set via the telephone line.

Next, the messages recorded on the response tape TP will be explained with reference to □ and FIG. 2.

A response tape TP is generated by key operation of the input section 8.

At this time, the control circuit 6 drives the plunger via the solenoid driver circuit 13 to put the tape TP and the side mechanism into the recording state, and also outputs a response/recording state.
The reception switching circuit 14 is switched to the response circuit side, and the motor M is driven via the motor driver circuit 11. At this time, the response tape TP is stretched from the beginning of the tape to point a (
(corresponding to the leader tape section) forms a blank section and stops at this point. By starting the mechanism at this point a, a normal answering message prompting the caller to record is recorded as the first answering message (OGMl).
Regarding the constraints on the OGM 10 time length, this example does not specifically stipulate, but it is assumed that once recording is started, the tape TP is run, and then the point where it stops is the end point. The range from this point to this point b is defined as the range of OGM 1. Next, by starting recording again from point b, a second response message (OGM2) is sent to the reception tape TP.
Record a message informing you that 2 has been recorded to the end and cannot record any more, and mark the end point as C.
shall be. Similarly, recording starts further from this 0 point, and as the third response message (03M3), when the message is forwarded, a forwarding notification message that clearly informs the loved one at the forwarding destination that the call is forwarded, such as "This call This is a message forwarding phone call. Please call ○○.'' Record a message such as "Please call ○○." That is, by notifying the loved one (00 himself/herself) who will receive the transfer, the call can be reliably made even if another receiver picks up the phone. Then, the tape is stopped at point d where the recording of OGM 3 is completed, and this point d becomes the message end of this response tape TP. In addition, the above points a to d
The point is set based on the count of pulse generation (falling edge thereof) by the Hall element based on the number of rotations of the reel base from the beginning of the tape, and is sequentially stored in the control circuit 5.

With the above configuration, the operation will be explained in the third section below.
This will be explained with reference to the flowchart shown in the figure.

First, a case where the answering state is set in the initial settings (step 21) will be described. There is an incoming call from the calling party at the input terminals T, T2 of the telephone line, and the call is input to the control circuit 6 via the ringer circuit 2 and the ringer detection circuit 3 (
Step 22). Therefore, it is determined in step 23 whether the number of rings set in advance by the input unit 8 is 2 or 4, and if the setting is 2, then step 24 is carried out, and if it is 4, then step 26 is carried out, and the control circuit 6 0FF-HO
An OK command is output to the interface circuit 4, and the telephone line enters the 0FF-HOOK state. Then, the control circuit 6 further determines in step 26 whether or not the receiving tape TP2 is in a recordable state. The tape is stored in memory, and judgment is made based on whether the tape capacity is full. If recording is possible, a 00M1 sending command is issued in step 27, and the control circuit 6 outputs control signals for driving the motor driver circuit 11 and solenoid driver circuit 13, and the mechanism unit 10
drives the response tape TP, switches the switching circuit 14 to the response side, and sends the response message of OGM1 through the tape amplifier 16 and the speech circuit 6, and further through the interface circuit 4 and the bridge rectifier circuit 1 to the telephone line. The caller is prompted to record on the receiving tape TP2. Here, the sending of the message of OGM1 is completed by detecting point b on the response tape TP by the count output from the reel rotation detection circuit 12.

Thereafter, in step 28, a command to record the received message is issued, the solenoid driver circuit 13 is driven by the output of the control circuit 6, the plunger and the switching circuit 14 are switched to the received message recording state, and the message is recorded via the telephone line. The caller's message is recorded on the receiving tape TP2.

Then, when the caller hangs up, the signal (voltage fluctuation or idle/green time detection signal for a certain period or more) is detected, and the control circuit 6 outputs the 0N-HOOK command to the interface circuit 4, and the 0N-HOOK command is output from the control circuit 6 to the interface circuit 4. Becomes HOOK state (Step 2
9). On the other hand, if it is determined in step 26 that the entire receiving tape has been recorded and no further recording is possible, the process proceeds to step 3o and issues a command to output the response message of 08M2. With this command, the response tape TP of the mechanism part 1o is run to point b of the tape TP without sending out the message of OGML, and by detecting this point by pulse counting due to the rotation of the reel stand,
The response message of 08M2 is sent in the 0FF-HOOK state. When the message sending reaches the 0 point on the tape TP and ends, the control circuit 5 outputs an 0N-HOOK command upon detection, and step 2
It becomes 9. In this step 29, the message recording operation for reception in the answering state is terminated, but if the presence or absence of message transfer (MT) setting is not determined in the next step 31, the operation is terminated.

Next, a case where the message transfer mode is set will be explained. Once the message forwarding mode is set,
After the receiving message recording operation is completed, the process passes through step 31 and proceeds to the next step 32. That is, in this step 32, the 0N-HOOK state is first entered in step 29, and after a certain timer time (for example, 16 seconds), the 0N-HOOK state is reached.
In the FF-HOOK state, the telephone number of the forwarding destination preset in the memory of the control circuit 6 is automatically dialed. After 0N-11001 in step 29, the message transfer setting is detected in step 31, and the response tape TP is transferred to the beginning of the OGMs, that is, the 0 point, before or during the timer time elapse. Drive and standby so that This 03M3 cueing is performed at least until the auto dialing is completed.

This auto dialing is performed by the control circuit 6 via the I) TMF generator 9a. After auto-dialing, in step 33, the response tape TP is played back and the message 03M3 is sent out. The transmission of this 00M3 message is, for example, within 2 minutes (step 34).
), if the security code is input during the transmission (step 36), the process proceeds to the next step 36. Here, the security code is set in advance by the person who set the forwarding destination in the input section 8 and the control circuit 6, and when this security code is input from the forwarding destination, it is transmitted via the telephone line to the bridge. Rectifier circuit 1 → interface circuit 4 →
By inputting the signal to the control circuit 6 via the speech circuit 6 and the DTMF receiver circuit 9b, the receiving message reproduction state of step 36 is established. This message was recorded in step 28 and is therefore the forwarded recipient (principal).
The contents can be known even after a short period of time has elapsed since the message was recorded for answer reception. In the call in step 34 above, the message recorded on 03M3 is repeatedly played and sent for the set time (2 minutes), but
Even if the person on the phone at this time is not the person who is being called, the call can be taken over because the name of the transferee to be called is recorded in VcOGM3 as described above. Further, the set time in step 34 continues even if the transfer destination is busy. If the security code is not input within the set time, the state will be 01i-1100 in step 3. Step 36
In the reception message reproduction state, the control circuit 6 reproduces the last message recorded on the reception tape TP2 of the mechanism section 10, and after a certain period of time has elapsed after the end of message transmission, the control circuit 6 Step 3
The program proceeds to step 7, where an 0N-1 (to 00) command is output, and the interface circuit 4 is placed in the 0N-noox state, thereby completing the message transfer operation.

Next, a case where the timer message transfer mode is set will be explained. When setting the timer message transfer mode, automatic dialing is not performed in step 31 and then in step 32 after the recording operation of the received message is completed, and the message is not automatically dialed until the timer time set in advance by the timer means is reached. All messages recorded on tape are transferred. To explain this operation with reference to Fig. 6, when the timer message transfer mode is set, when the recording operation of the received message is completed, the state is 0N-HOOK, and the answering mode is maintained until the next call arrives. Wait there. When the timer time preset by the timer means is reached, it is determined in step 62 whether or not the time coincides with the current time. If the time coincides, the process proceeds to step 63 and it is determined whether or not there is a message on the receiving tape. This determination of the presence or absence of a tape message for reception is carried out by inputting pulses from the reel rotation detection device 12 into the control circuit 6 and counting them. If the current time does not match the timer time in step 62, it is held in the ON-HOOK state in step 61-, and if it is determined in step 63 that there is no message, it is held in the ON-HOOK state in step 61. On the other hand, if it is determined in step 63 that there is a message, the process advances to the next step 64. This step 6
In step 4, the state is first set to 0N-HOOK in step 61, and after a certain timer time (for example, 16 seconds), the 0N-HOOK state is reached.
In the FF-HOOK state, the telephone number of the forwarding destination preset in the memory of the control circuit 6 is automatically dialed. Here, after 0N-HOOK in step 61 above, step 5
2. Detect the message transfer setting in step 63, and drive the response tape TP to the beginning of 03M3, that is, the 0 point, and keep it on standby before or during the timer time elapse. . This 03M3 cueing is performed at least until the auto dialing is completed. This auto dialing is performed by the control circuit 6 via the DTMF generator e&. After auto-dialing, in step 66, the response tape TP is played back and the message 03M3 is sent. This OGMa
The message will be sent within, for example, two minutes (step 66), and if the security code is input during the sending (step 67), the process will proceed to the next step 68. here,
The security code is set in advance by the transfer destination setter in the input section 8 or the memory section of the control circuit 6. When this security code is input from the transfer destination, the bridge rectifier circuit 1 → By inputting the received signal to the control circuit 6 via the interface circuit 4→speech circuit 6→DTMF receiver circuit 9b, the receiving message reproduction state is entered in step 68. This message was recorded in step 28 and is therefore the forwarded recipient (
person) can know the contents of the message recording for answer reception. In the call to step 66 above, 03
The message recorded on M3 is played repeatedly for a set time (2 minutes) and sent out, but even if the person on the phone at this time is not the person who was called, the transferred recipient will be called on 03M3 as described above. Since the name of the person is recorded, it can be inherited. Further, the set time in step 66 continues even if the transfer destination is busy. If the security code is not input within the set time, the state will be 0N-1001m in step 5e. In the reception message reproduction state of step 6B, the control circuit 6 is connected to the reception tape T of the mechanical unit 10.
All the messages recorded on P2 are played back, and the receiving tape TP2 of the mechanism section 1o is rewound at high speed to the beginning of the tape. After a certain period of time has elapsed after the end of this message transmission, the control circuit 6 proceeds to step 69 and outputs the ON-HOOK command, setting the interface circuit 4 in the ON-HOOK state and completing the message transfer operation.

Effects of the Invention As described above, according to the present invention, when forwarding a recorded message to a caller, the forwarding destination is automatically dialed and the message is forwarded only when a preset time has arrived. It is possible to provide an extremely excellent telephone answering machine that allows the young person to receive message forwarding only when it is convenient for him/herself, and that can reliably accomplish the original purpose of message forwarding.
