Abstract

PURPOSE:To listen to only the massage that is not listenal and to automatically set a waiting mode after listening by storing the start point and end point of the message, which is stored in a tape for reception, in a memory. CONSTITUTION:When a PLAY key 3-1 is depressed in the automatic answering mode of an automatic answering telephone system, the rewinding of a tape 8 is started after the position of the tape 8 for reception at that time is stored in the memory. This rewinding is started from the position where the PLAY key 31 is depressed the last time (the data of the position are stored in the memory at the beginning of that time) or when the PLAY key 3-1 is not depressed the last time, rewinding is continued to the start point of the tape and switched to reproduction later. When the tape 8 for reception reaches the position of the tape where the PLAY key 3-1 is depressed, reproduction is stopped and after several seconds, the waiting state is automatically recovered. Therefore, the message from a caller recorded in the tape 8 for reception can be heard just by depressing the PLAY key 3-1 and the waiting state is automatically recovered.

[Function] PLAY in the answering mode of the answering machine
When the key is pressed, the position of the receiving tape at that time is stored in the memory and then the rewinding of the receiving tape is started.
This rewind is played at the position where the PLAY key was pressed last time (the position data is stored in the memory at the start point of that time) or when the PLAY key was not pressed last time, after rewinding to the tape start point. Switch to. When the receiving tape reaches the position of the tape on which the PLAY key is pressed, the reproduction is stopped, and after a few seconds, the reproduction is automatically restored to the standby state.

[0006]

The structure and function of the present invention will be described below. FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a one-chip microprocessor (CP
U), the memory RO in which the program is stored
M, a RAM (including a register) that is a memory for storing and processing data at the tape position is built in.
The AM data is backed up by the backup battery 2. I-1 is an input port, O-1 is an output port, I / O-1 to I / O-4 are input / output ports, I
NT is an interrupt terminal, and T1 is a count input terminal.

Reference numeral 3 is a keyboard having a "play" key,
4 is a tape drive circuit for driving the receiving tape 8 in a rewinding state, a reproducing state, etc., 5 is a microphone for recording a response message, and 6 is a response message (OGM) for the I / O-1. This is an OGM recording / playback unit that records or plays back under the control of. Further, 7 is an ICM recording / reproducing section for recording or reproducing a message (ICM) from a calling party under the control of the I / O-4, and 8 is for recording a message (ICM) from the calling party. A receiving tape, 9 is an erasing head, and 10 is a recording / reproducing head.

Reference numeral 11 is a light emitting diode, 12 is a phototransistor, and a shutter 13 interlocking with a reel stand (not shown) of the receiving tape 8 is arranged between the light emitting diode 11 and the phototransistor 12, and A pulse train corresponding to the running of the receiving tape 8 is output from the phototransistor.

The pulse train is applied to the count input terminal T1 and stored in the RAM as position data of the receiving tape 8 as described later. Reference numeral 14 is a line monitoring circuit capable of detecting a calling signal and a caller's on-hook, 15 is a line transformer for connecting the telephone lines L1 and L2 to the present apparatus, and 16 is a speaker.

Next, a series of operations as an answering machine will be described with reference to the flowchart of FIG. When the power of this device is turned on, it will be in the absence mode, and step 20
It becomes a standby state waiting for the arrival of the calling signal of. In step 21 where the call signal does not come, the PL of the keyboard 3
The interruption of the AY key 3-1 (playback key) is permitted.

When a calling signal originated by the calling party is applied to the telephone lines L1 and L2, the calling signal is detected at step 20 through the line monitoring circuit 14 and the input port I-1. Step 20 is affirmative. Then, the interruption of the PLAY key is prohibited (step 22), the relay Y-1 is turned on, and the telephone lines L1 and L2 are closed via the contact point y1-1. At this point, the ringing signal is stopped, and the caller and the device are in a call state.

Then, the command from the I / O port I / O-1 starts the transmission of the response message (OGM) previously recorded in the OGM recording / reproducing unit 6 (step 24). At the next step 25, it is determined whether the sending of the response message is completed or not at the input / output port I / O-
Detected via 1. When the sending of the response message ends, step 25 becomes negative, and the beep tone made by the program is sent through the output port O-2, the amplification circuit (not shown) of the OGM recording / playback unit 6, and the line transformer 15. (Step 26).

In the next step 27, the counter built in the CPU 1 is started, and when the running of the receiving tape is started as described below, counting of the pulse for determining the position of the tape is started.

Subsequently, the receiving tape 8 is driven via the tape driving circuit 4, and the ICM recording / reproducing section 7 is switched to recording by a command from the input / output port I / O-4, whereby the receiving tape 8 is received. Start recording a message from the caller.

When the running of the receiving tape 8 is started as described above, the shutter 13 which rotates in accordance with the running of the receiving tape 8 blocks the light beam from the light emitting diode 11, so that the phototransistor 12 outputs a pulse train. Then, this pulse is counted by the counter.

If the capacity of the counter is sufficient while the receiving tape is running, the data of the counter can always be stored in the counter, but if the counter has a small capacity such as 8 bits. Alternatively, the counter data may be transferred to the memory RAM.

Now, in the recording of the caller's message described above, in step 29, the caller makes a telephone call (not shown).
Continue until you go on-hook. This on-hook of the caller is detected via the line monitoring circuit 14 when the caller changes the voltage of the telephone line when the caller is on-hook.

Here, the recording is stopped (step 3
0), the above up counter also stops (step 3
1) The relay Y-1 is turned off to release the above-mentioned telephone line closure (step 32), and the standby state of step 20 is restored.

The above operation is repeated for each incoming call, and the caller's message is stored in the receiving tape 8.

Next, the owner of the apparatus returns home, and in order to reproduce and listen to the caller's message recorded on the above-mentioned receiving tape, the soft touch PLAY key 3- of the keyboard 3 is used. Press 1. Here, the subroutine "PLAY" in FIG. 3 is called by the interrupt operation.

Here, for the sake of convenience, the case where the PLAY key 3-1 is first pressed to listen to the messages from a plurality of callers for the first time is the first round, and after that, the messages are recorded from the callers, and the second time is described above. Press the PLAY key 3-1
The case of listening to the message from the caller who has not been heard is called the second round.

A register (not shown) in the CPU 1 serves as a round counter for storing the maximum value of the round in order to store the number of rounds.
I'm using one of Since this register can specify the address of the memory RAM in the CPU 1, data can be written to the RAM at that address or the RAM can be specified.
The data stored in can be read.

The initial value of the round counter is "0". That is, when the receiving tape 8 is newly inserted,
Alternatively, the round counter is set to "0" by a program through a contact (not shown) which switches when the tape is exchanged, and the receiving tape 8 is rewound to the starting point (this flowchart is not shown). ).

For convenience, the address of the RAM when the round counter is "0" is "0" as shown in FIG.
And The data in the RAM at this time is "0" because the receiving tape 8 used in this embodiment has no leader tape and can record the message of the caller from the tape starting point.
Is. When a receiving tape with a leader tape is used, the data is not "0", for example, "10", because the tape is in a standby state after passing through the leader tape.
The data "0" is entered.

Now, as described above, for the first time the PLAY key 3 is pressed.
When -1 is pressed, the round counter becomes "1" in step 40. At this time, if the up counter counts, for example, "1234" as the tape running amount, this count value is transferred to the RAM of the address "1" (steps 41 and 42).

In the next step 43, in order to determine the rewinding amount of the receiving tape 8, the data of the RAM in the preceding stage, that is, the data of the address "0" this time is read, for example, register 0 (not shown). Transfer to.

In the next step 44, the up counter is started as a down counter. CP
Since the counter built in U1 is only an up counter, it is processed by a program and used as a down counter. Moreover, the rewinding of the receiving tape 8 is started (step 45).

Then, in step 46, the count value of the down counter ("0" in the above example) and the value of the register 0 ("0" in the above example and "()" means data. ) Is affirmative, step 46 is affirmative, the above-described rewinding is stopped, and the down counter is switched to the up counter (steps 47 to 49).

Further, in the next step 50, R of the next stage
With the data of AM, that is, the data "1234" at the address "1" shown in FIG. 4, the data transferred to the memory RAM in step 42 is transferred to, for example, the register 1 (not shown).

Then, the reproduction of the receiving tape 8 is started (step 51), and when the count value of the up counter indicating the running amount of the tape coincides with the value of the register 1 ("1234" in the above example), step 52. Becomes affirmative, and the beep tone generated by the program is amplified by the speaker 16 via the input / output port I / O-4 and the amplification circuit (not shown) of the ICM recording / playback unit 7, and the message from the caller is sent. The owner is notified that the reproduction is completed (step 53).

Then, the 5-second timer is operated (step 54). If necessary, an operation such as rewinding the receiving tape by an appropriate amount and then reproducing it can be performed during the operation of the 5-second timer, but the flowchart is not shown because it is not directly related to the present invention.

When the above 5 seconds have passed, this subroutine is terminated and the standby state waiting for the incoming call signal in step 20 of FIG. 2 is automatically restored.

After returning to the standby state as described above, several messages from the caller are recorded, and when the owner presses the PLAY key for the second time, the round counter is clear as described above. Is "2", memory RAM
Is "2", and the tape running amount up to this time is "2468" shown in FIG. 4, for example, and the receiving tape is the starting point of this round (or also called "starting point of the round"). After rewinding to "1234" indicating "," reproduction is switched to, playback of the receiving tape 8 is stopped at the tape position "2468", and the standby state is restored after several seconds.

[0034]

As described above, according to the present invention, when a message from a caller recorded on a receiving tape is reproduced and listened to, a message which has not been listened to can be displayed by simply pressing the PLAY key. It is efficient because it can be heard and automatically returns to the standby state.
