Abstract

PURPOSE:To prevent malfunction of an automatic reply device by setting and recording a pattern of end signal of a reply message, reproducing and sending a signal recorded through automatic incoming, detecting the end signal from the sent signal and stopping the transmission. CONSTITUTION:An end signal pattern setting means 100 sets a pattern of an end signal of a reply message where a sound signal of a prescribed audible frequency and a silence signal are repeated, a recording means 101 records a reply message including a music and records the end signal of the pattern set to the end of the reply message. A call incoming automatically is reproduced by a reproducing means 102 and sent to a line. A pattern end signal detection means 104 monitors a signal sent to the line to stop the drive of the reproducing means 102 when the end signal of the set pattern is detected. Since the end signal having the set pattern is rarely included in a music, malfunction due to mis-detection of the end signal is prevented.

Conventionally, when an automatic response device of this type records a response message in advance, it records a 1K message at the end of the response message, for example.
The end signal of a predetermined audible frequency of Hz is recorded for a continuous period of, for example, one second, and when a call is automatically received, this response message is played back and sent, and when the end signal is detected, it is determined that the sending of the response message has ended. ing.

Problems to be Solved by the Invention However, since the conventional automatic response device described above uses an end signal of an audible frequency, the music superimposed on the response message is a signal with the same frequency and duration as the end signal of the response message. If it includes, there is a problem of malfunction.

If you use terminal a to set the end signal of a pattern where the sound time is 0.15 seconds and the silent time is 0.3 seconds, the sound time will be 0.15 seconds. Silence time is 0.4
A terminal C is provided for setting the end signal of the 5 second pattern, and each setting signal is detected by the microprocessor 16.

The microprocessor 16 includes a timer 17 for measuring the sound time and silent time of the end signal of the response message;
It is equipped with a counter 18 for counting the number of repetitions of the end signal of the response message, and is based on the detection signals of the incoming call detection circuit 2, the silence detection circuit 4, the filter circuit 5, the pattern setting switch 19, and the detection signal of the operation section (not shown). , controls the office line switch 3, amplifier 6.9.11.13, oscillator 14, and deck 15, as will be described later.

Next, we will discuss the operation of the above embodiment, especially the microprocessor 16.
The operation will first be explained for the case where a response message including music is recorded.

In FIG. 1, when an operator (not shown) starts recording a response message, the amplifier 9.11 is driven and the deck 15 is controlled to be in a recording state.

Therefore, when music is input from the external input terminal 1o and a response message is input from the microphone 12, the respective audio signals are amplified and mixed by the amplifiers 9 and 11, and then recorded on the recording/playback head 7 and the magnetic tape 8. Ru.

Next, when the operation unit performs an operation to end recording of the response message, the drive of the amplifier 9.11 is stopped, and the oscillator is activated according to the pattern set by the pattern setting switch 19 and the number of repetitions set in advance in the counter 18. 1
4, and the deck 15 is stopped.

Therefore, as shown in FIG.
At the end of the response message on which the music is superimposed, the end signal of the pattern set by the pattern setting switch 19 is repeatedly recorded.

Next, the operation when sending a response message will be explained with reference to FIG.

When a calling signal is input from the office line through terminal 1 and the incoming call detection circuit 2 detects this signal, it closes the office line by controlling the office line switch 3, drives the amplifier 6, and also switches on the deck. 15 to the playback state.

Therefore, as shown in FIG.
The signal is reproduced by the amplifier 6, amplified by the amplifier 6, and sent to the office line via the office line switch 3 and terminal 1.

In this case, in step 31 shown in FIG. 4, a predetermined frequency (l K H
It is determined whether or not a sound signal of z) is detected, and if this signal is detected, the process proceeds to step 32 and subsequent steps.

In step 32.33, the timer 17 determines whether the duration of the sound signal is 0.15 seconds or not, and if the sound signal continues for this time, the process proceeds to step 34 and thereafter;
If not to continue, return to step 31.

Therefore, even if the response message or music contains a signal of the same frequency as the sound signal, if it does not continue for 015 seconds, it will not be determined as the end signal of the response message.

In Steps 34, 35, and 36, the set time of the silent time is determined based on the setting status of terminals a, b, and c of the pattern setting switch 19, and the determination results are shown in Step 3.
7.38.39, the end signal silence time (0, 1
5 seconds, 0.3 seconds, 045 seconds) and proceed to step 40.

In step 40, it is determined whether or not the silent time has reached the set value based on the detection signal of the silent detection circuit 4, the set value of the silent time, and the timer 17, and if the silent time has reached the set value, step 4
1, and if not reached, return to step 31.

Therefore, if the silent period does not continue for the set time, the detection of the end signal is invalidated, and the end signal is detected from the beginning again from step 31.

In step 41, the counter 18 is incremented,
In the following step 42, the value of the counter 18 changes to the set value (
For example, it is determined whether or not it is "3"), and in the case of No, the process proceeds to step 43.

In step 43, based on the detection signal of the filter circuit 5,
By determining whether or not a signal of a predetermined frequency (I KHz) is detected, it is determined whether or not a sound signal of the next period is detected, and if it is not detected, the process returns to step 31 and ends. Signal detection is performed from the beginning, and when a signal is detected, the process returns to step 32 to detect the next cycle of a sound signal and a silent signal.

In step 42, when an end signal of a sound signal and a silence signal is detected for a predetermined number of repetitions of "3", step 4
4, the detection of the end signal is regarded as valid, and the driving of the amplifier 6 is stopped, the central office line is opened by controlling the central office line switch 3, and the reproduction is stopped by controlling the deck 15. and cue up.

Therefore, according to the above embodiment, when the response message includes music, it is rare for the music to include frequency components of the above pattern, and malfunctions can be prevented.

Additionally, if music is recorded that includes a signal with the same frequency components and duration as the set pattern, the pattern can be changed by changing the pattern using the pattern setting switch 19.
Malfunctions can be prevented.

It goes without saying that the end signal is not limited to the pattern and frequency described above.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention includes means for setting a pattern of an end signal of a response message in which a sound signal and a silent signal of a predetermined audible frequency repeat, and an end signal of a pattern set by the setting means. When a call is automatically received, this recorded signal is played back and sent out, and when the end signal of the pattern is detected, the signal transmission is stopped. It is rare for music to include a signal with a repeating pattern of a sound signal and a silent signal for a predetermined period of time. Therefore, it is possible to prevent malfunctions due to erroneous detection of an end signal.
