JPH0514477A - Automatic answering telephone set - Google Patents

Abstract

PURPOSE:To avoid a trouble and to eliminate the need for reproduction operation when a message recorded during absence is heard by allowing an acoustic reproduction means to reproduce a message automatically when the message is recorded on a message recording area based on a detection output from a human body detection means. CONSTITUTION:When a possessor of the automatic answering telephone set returns to his room and is close to a sensing range of an infrared ray sensor 9, the infrared ray sensor 9 outputs an output signal in response to the accessed distance to a comparator circuit 10. The comparator circuit 10 compares the output signal from the infrared ray sensor 9 with a preset threshold level and outputs a sensing signal to a microprocessor 20 when the output signal exceeds the threshold level. When the microprocessor 20 detects the detection signal from the comparator circuit 10, the microprocessor 20 discriminates it that the possessor returns to its room and uses a message presence destination means 21 to discriminate whether or not a message is recorded in a message recording area 5 and when the message is recorded, the message is reproduced from a speaker 12 via a voice output circuit 11.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an answering machine, and particularly when a message is recorded, the message is automatically reproduced when the owner returns and approaches the answering machine. It is configured so that it can be heard.

[0002]

2. Description of the Related Art In a conventional answering machine, when the owner returns and listens to a message recorded while he / she is away, he / she manually operates a switch to perform a reproducing operation.

[0003]

As described above, in the conventional answering machine, when listening to a message recorded during absence, an operation for reproduction is required, which is troublesome and the message is not recorded. There is a problem that it is difficult to understand because you have to look at the display to know whether or not it is present.

[0004]

Therefore, the present invention has been conceived in order to solve such a problem, and includes a message recording area for recording a message and a human body detecting means for detecting the approach of a human body. The sound reproducing means is provided, and based on the detection output from the human body detecting means, the message is reproduced from the sound reproducing means when the message is recorded in the message recording area.

[0005]

[Function] Since the answering machine is provided with the human body detecting means, when it is detected that the owner has returned to the room,
Since the message can be automatically reproduced from the message recording area, if the message addressed to the owner is recorded, the message can be heard immediately.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, an answering machine has an office line connection terminal 1 for connecting an office line, an incoming signal detection circuit 2 for detecting an incoming signal, and a microprocessor 20 for controlling the entire device. And a line switch 3 for closing the line, a voice circuit 6, and a receiver 7 and a microphone 8 connected to the voice circuit 6, and further being absent from the caller. It is provided with a response message sending circuit 4 for notifying a message, a message recording area 5 for recording a message, and a message presence / absence determining means 21 for determining whether or not a message is recorded in the message recording area 5.

In addition to the above, the answering machine includes an infrared sensor 9 for detecting the approach of a human body, and a comparison circuit 10 for judging whether or not the output of the infrared sensor 9 exceeds a certain threshold value. There is.

Next, the operation of the answering machine having the above arrangement will be described. When the caller receives an incoming call, the incoming call signal is applied to the incoming call detection circuit 2 from the station line connection terminal 1, and the incoming call detection circuit 2 outputs the detection signal to the microprocessor 20. The microprocessor 20 has an incoming detection circuit 2
Upon detecting the detection signal from, the station line switch 3 is closed, and subsequently the response message sending circuit 4 is activated to send a reply message to the caller to the effect that the caller is out. Then, the message from the caller is recorded in the message recording area 5.

When the owner of the answering machine returns to the room and approaches the detection range of the infrared sensor-9, the infrared sensor-9 compares the output signal corresponding to the approached distance with a comparison circuit.
Output to 10. The comparison circuit 10 compares the output signal from the infrared sensor-9 with a preset threshold value (for example, a value when approaching up to 3 m), and when the threshold value is exceeded, the detection signal is sent to the microprocessor 20. Output.

Upon detecting the detection signal from the comparison circuit 10, the microprocessor 20 determines that the owner has returned to the room, and the message presence / absence determining means 21 records a message in the message recording area 5. If it is recorded, it is determined whether or not there is a speaker 12 through the audio output circuit 11.
Play more.

(Other Embodiments) When a human body approaches the answering machine and an output signal is generated from the infrared sensor 9 after a message from a caller is recorded in the message recording area 5, the microprocessor 20 Starts the timing operation of the first timer 13 and waits for a predetermined time to elapse. After the output from the first timer 13 after a predetermined time has elapsed, the microprocessor 20 reproduces the message recorded in the message recording area 5 from the speaker 12 via the voice circuit 11.
The message can be prevented from being cut off and can be heard after the user is in a relaxed state.

When the answering set switch 15 is set, the microprocessor 20 starts the time counting operation of the second timer 14, and after a predetermined time has elapsed, the second timer 14 is started.
If the infrared sensor 9 is disabled by not accepting the output of the comparison circuit 10 until the end of the time counting operation of the above, the operation of the human body detecting means after the owner has sufficiently left from the answering machine. It is possible to prevent the erroneous reproduction during the presence in the room after the setting.

[0013]

According to the answering machine of the present invention, since the human body detecting means for detecting the approach of the human body is provided, when the owner returns to the room, the message addressed to the owner is recorded. For example, since the message is automatically played and the message can be heard, it is not necessary to care whether the message is recorded or not, and the operation of listening to the message is extremely simple. .
