Abstract

PURPOSE:To improve the effect of crime prevention without giving any unpleasant feeling to a caller by opening a line if the voice from the caller is not detected even after the voice response is repeated after the closing of the telephone line in an automatic answering device of an user's telephone set. CONSTITUTION:When a call signal is incoming, a control section 2 detects it and transmits it to a control circuit 5, then a line closing signal is fed to the control section 2, which closes the telephone line 1. Then a response message is transmitted for a prescribed number of times from a voice response section 6, a changeover switch 8 is switched during the period when no response message is transmitted and the response from the caller is awaited. When the voice of the caller is incoming, the voice response section 6 transmits the automatic answering message. If no response comes from the caller, the telephone line 1 is opened. In using a voice by means of reproduction of a tape, the caller cannot recognize it as the voice from the automatic answering device only with listening to the voice response.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an in-room telephone device that automatically answers a call, records a caller's message, and monitors or controls indoor devices. It concerns a response device.

[Background technology]

Conventionally, answering machines that automatically answer upon receiving a call signal and record a message of the caller's name, or telephone units that monitor or control the status of each glaze sensor, air conditioner, lighting equipment, etc. "Hello ○○
It's O○. I'm away at the moment. ”, ``I'm out of the office,'' etc., and then it starts recording the caller's message, and if a PIN is entered, it can monitor the indoor equipment or perform surveillance, etc. It had started. However, as mentioned above, telling an unspecified caller that you are away is extremely problematic in terms of crime prevention; If the caller is silent, the device will not transmit audio, which will cause discomfort if the caller is making a call. It's difficult. In other words, if the time until the line is released is short, even if the caller intends to make a call, if the device side does not say anything, there is a risk that the caller will lose the timing to say something and the line will be abandoned. It is necessary to open the line for calls as soon as possible. Furthermore, if the first response sound is "Moshi-moshi" and this is sent as a synthesized voice, there is a high risk that the caller will realize that it is some kind of answering device. [Purpose of the present invention] The purpose of the present invention is to prevent the caller from repeating voice responses after the telephone line is closed, thereby causing discomfort to the caller, and to prevent the telephone line from being closed in response to malicious calls. Another purpose is to improve the crime prevention effect by making it impossible to tell that the answering device is an answering machine just by listening to the voice response after the telephone line is closed.

[Disclosure of the invention]

Embodiment In FIG. 1, (1) is a telephone line, which is connected to a control unit (2), and the control unit (2) has a reputation detection and self-#J response function, and a telephone line (3). Connecting. (4) is an input/output interface, which is connected to the control circuit (5). It is equipped with a III control circuit (5), CPU, ROM, RAM, etc. (6) is the voice response section, and (7) is the voice test 1. i
-1 capital, (8) is a changeover switch, and control circuit (5
) is switched according to the output.

When a calling signal like the one in No. 22(a) arrives from the telephone line (]) made by m11, the control 5(2) detects this calling signal and
A calling signal detection signal as shown in Figure (b) is transmitted to the control circuit (5) via the input/output interface (4). The control circuit (5) thereby becomes an input/output interface (4).
A signal for disconnecting the line 1Y as shown in FIG. 2(c) is transmitted to the control section (2) via the control section (2), and the control section (2) closes the telephone line (1). After that, as shown in FIG. 2(d), the voice response unit (6)
A response message is sent out a fixed number of times, and during a period in which no response message is sent out, the selector switch (8) is switched to wait for a response from the calling party. When the caller's voice arrives as shown in Figure 2(e), the voice response unit (6) sends an answering message indicating that the caller is not at home as shown in Figure 2(f).After that, the answering machine function is activated. Start the telephone control function. If there is no response from the caller, the telephone line 1+) is released.

Second Embodiment vj Figure 3 shows a second embodiment of the present invention, in which (9) is a tape playback unit that plays back an endless recording of real voices, and only the first response message is recorded on this tape. The caller is sent from the playback section (9), and when the caller makes some kind of response, a voice synthesized voice is used to inform that the caller is away. In other words, after automatic response, selector switch (8)
is turned to the b side, the caller's response tone is immediately played back, and a response tone is started to be transmitted. During the silent period of the endless tone, the voice detecting section (7) detects the caller's response tone. This system can be easily configured by simply adding a tape playback unit (9), and the first answer tone alerts the caller to the answering device R.
It does not make you think that ft has responded.

〔Effect of the invention〕

As described above, the present invention opens the telephone line if no voice is detected from the caller even after repeating the voice response after the telephone line is opened, so the voice response is repeated after the telephone line is closed. In addition to preventing the caller from feeling uncomfortable when making a call, the telephone line can be opened to malicious calls, and furthermore, the voice response after the telephone line is closed can be reproduced by the playback unit to reproduce the real voice. Therefore, it is possible to prevent the user from knowing that it is an answering machine Fjt just by listening to the voice response after the telephone line is closed, and the crime prevention effect can be improved.
