The operation of the apparatus according to the present invention, particularly the operation of the control unit 170 of the cordless telephone 100 will be mainly described with reference to FIGS. A case where a human sensor is provided as the sensor 816 in the door phone 810 or the door phone monitor 820 will be described.

  As shown in FIG. 8, in step S201, the control unit 170 of the base unit 100A sets the answering machine function to be valid or invalid based on, for example, a signal input from the answering machine function setting switch 120, and sets the answering machine function. Is disabled, the sensors 816 and 826 are set to the off state to perform normal processing. On the other hand, when the telephone answering machine function is enabled, the process proceeds to step S202. The set sensor 826 is set to an on state. Hereinafter, for example, the operation of the control unit 170 when the answering machine function is valid will be described.

The control unit 170 includes a timer that measures a specified time, for example.
This timer is mainly used to discriminate between an intruder and the user himself / herself. If the e-mail is immediately sent to the user's mobile phone or the terminal device 50 when the sensor 816 reacts, the movement of the user who has returned home is detected by the sensors 816 and 826, and the e-mail is sent. Will end up.

Therefore, since an e-mail is transmitted to a mobile phone or the like every time the user returns home, a timer is used in this embodiment in order to prevent this problem. The set time of the timer is set to be approximately equal to the time required for the setting of the answering machine function to be canceled after the user comes home and is detected by the sensors 816 and 826. Normally, the answering machine function is set and canceled by an operation button on the main unit 110a. Therefore, when it is detected by the sensor 826, the set time of the timer is considerably shortened, and the doorphone remote from the main unit 110a is used. When it is detected by the sensor 816 of 810, the set time of the timer becomes long. For example, when the sensor is provided in the main unit 110a body, the set time of the timer becomes relatively short.

  The control unit 170 proceeds to the process of step S204 when the abnormality detection by the sensors 816 and 826 continues for a set time of the timer or more, otherwise, the control unit 170 remains in the process of step S202.
