JPH06164700A - Telephone set with automatic answering function - Google Patents

Abstract

PURPOSE:To easily operate a telephone set and to prevent an automatic answering function from being forgotten to turn on by utilizing the signals of the presence and absence of a human body from a human body detection means and automatically switching the operating state of the automatic answering function. CONSTITUTION:First, the presence and absence of the human body is detected by detecting infrared rays emitted from the human body by a human body detection sensor 1 for which a pyroelectric infrared ray sensor is used. Then, signals from the human body detection sensor 1 are processed by a signal processing circuit 2, the signals of the absence of the user of the telephone set are outputted when no human body is detected continuously for 5 minutes for instance and the signals of the presence are outputted in the other cases. Then, by using the signals, an automatic answering function control circuit 3 operates the automatic answering function when the user is absent and stops the automatic answering function when the user is present. Thus, the automatic answering function of the telephone set with the automatic answering function can be in a state corresponding to the presence and absence of the human body without a manual operation.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone with an answering machine.

[0002]

2. Description of the Related Art Generally, a telephone with an answering machine functions in the same manner as a telephone without an answering machine by stopping the answering machine when the user is at home, and also when the user goes out. In such a case, by operating the answering machine function, it is possible to receive a message from a telephone that is not in the office, store the message, and listen to the stored message after returning home.

[0003]

However, in such a conventional telephone with an answering machine, the user has to operate / stop the answering machine every time he / she goes out or returns home.

[0004]

As means for solving the above problems, a telephone with an answering machine according to the present invention is provided with a sensor for detecting the presence or absence of a human body, a circuit for processing a signal from the sensor, and a circuit for processing the signal from the sensor. And a circuit for controlling the operating state of the answering machine function according to the processing result.

[0005]

In the telephone with an answering machine of the present invention constructed as described above, the presence or absence of the user is detected by the human body detecting means. Therefore, by using this signal to switch the operating state of the answering machine, it is possible to automatically switch the operating state of the answering machine corresponding to the presence or absence of the user. Further, since the user is not always within the detection range of the human body detection means, a signal processing circuit for performing processing such that if the human body is not detected for a certain period of time, it is determined that the user has gone out. It is possible to provide a telephone with an answering machine having an advanced automatic answering machine automatic switching function with less malfunction by providing the.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a telephone with an answering machine function according to the present invention will be described in detail below with reference to the drawings. 1 is a schematic view of a telephone with an answering machine showing an embodiment of the present invention, FIG.
2 is a flow chart for explaining the operation of the schematic view of FIG. 1. First, the presence or absence of a human body is detected by detecting infrared rays emitted from the human body by the human body detection sensor (1) using a pyroelectric infrared sensor. Next, the signal from the human body detection sensor is processed by the signal processing circuit (2). For example, if there is no human body detection for 5 minutes in a row, the user of the telephone is absent. Give out. Then, using this signal, the answering machine function control circuit (3) operates the answering machine function when the user is absent, and stops the answering machine function when the user is present. As described above, the answering machine function of the telephone with an answering machine can be brought into a state corresponding to the presence or absence of a human body without human operation. Although a pyroelectric infrared sensor is used as the human body detection sensor here, other infrared sensors such as a thermoelectric infrared sensor may be used, or a human body may be detected by another method such as an ultrasonic sensor.
The time for determining the absence of the user is set to 5 minutes here, but may be other than this.

[0007]

As described above, the present invention has an industrial value in that it simplifies the operation of a telephone with an answering machine and can provide a telephone with an answering machine without forgetting to switch the answering machine.
