  In step S2, it is determined whether the message transmission condition is satisfied. If the message transmission conditions are met (Yes in step S2), the process proceeds to step S21 (C). If the message transmission conditions are not met (No in step S2), the process proceeds to step S3.

  In step S3, it is determined whether the infrared sensor 3 has detected a person. When the infrared sensor 3 detects (Yes in Step S3), the process proceeds to Step S4, and the detected time is stored as sensor information (Step S4). When the detection is not performed by the infrared sensor 3 (No in step S3), the process proceeds to step S31 (D).

  In step S5, it is determined whether there is a new message. When the message processing means 21 receives a new arrival message, the message incoming detection means 10 of the charger 1 can detect the presence of a new arrival message by receiving message reception information via the short-range wireless communication circuit 105. it can.

  If there is a new message (Yes in step S5), the process proceeds to step S6. If there is no new message (No in step S5), the process proceeds to step S1 (A).

In step S <b> 7, notification to the subject is performed using the drive leg 8. The operation of the drive leg 8 is determined based on the sender ID, and the operation for each sender is executed.

  In step S8, it is determined whether the infrared sensor 3 has detected a person. When the infrared sensor 3 detects (Yes in Step S5), the process proceeds to Step S6, and the detected time is stored as sensor information (Step S6). In step S <b> 7, notification to the subject is performed using the drive leg 8. Thus, notification can be performed after confirming that the subject is in the vicinity, and unnecessary notifications can be reduced.

  If the portable device 2 is not attached in step S1 (No in step S1), the process proceeds to step S11 (B) in FIG. In step S11, it is determined whether the infrared sensor 3 has detected a person. When the infrared sensor 3 detects (Yes in Step S11), the process proceeds to Step S12, and the detected time is stored as sensor information (Step S12). And it notifies to a subject using the drive leg 8 (step S13).

  If the message transmission condition is met in step S2 (Yes in step S2), the process proceeds to step S21 (C) in FIG. In step S <b> 21, it is determined whether a sensor information output request has been made via a message transmitted to the mobile device 2.

  When a sensor information output request is made (Yes in step S21), the stored earliest sensor information is output to the portable device 2 by the short-range wireless communication circuit 105 (step S22). Then, the CPU 101 gives a transmission command to the portable device 2 so as to transmit the contents of the sensor information as a message to a registration destination registered in advance (step S23). This transmission command is given to the portable device 2 via the short-range wireless communication circuit 105.

  A transmission command is given to the message processing means 21 via the short-range wireless communication circuit 206. The message processing means 21 transmits an email containing the delivered sensor information to one or more registration destinations registered in advance as contact information. In this embodiment, a message transmission instruction is issued via the short-range wireless communication circuit 105, but a message transmission command or the like may be transmitted using electromagnetic coupling of the charging circuit.

  If the sensor information output request has not been made (No in step S21), the sensor information is periodically reported to the registration destination (S24). When the earliest sensor information has already been notified to the registrant (Yes in step S25), the process returns to step S1 (A). If the earliest sensor information has not been notified to the registrant yet (No in step S25), the stored earliest sensor information is output to the portable device 2 via the short-range wireless communication circuit 105 (step). S26). Then, the CPU 101 gives a transmission command to the portable device 2 so as to transmit the contents of the sensor information as a message to a registered destination registered in advance (step S27).

  When the detection is not performed by the infrared sensor 3 (No in step S3), the process proceeds to step S31 (D) in FIG. In step S31, it is determined whether or not a person has been detected by the infrared sensor 3 for a predetermined time.

  If a person is detected by the infrared sensor 3 during a predetermined time (Yes in step S31), the process returns to step S1 (a). If no person is detected by the infrared sensor 3 for a predetermined time (No in step S31), it is determined that the location of the subject is unknown (S32). The CPU 101 gives a transmission command to the portable device 2 so as to transmit the message to the registered destination registered in advance using the determination content as the content of the message (step S37).

  A communication circuit may be provided on the charger 1 side, a message communication program such as a mailer may be installed, and the message may be transmitted from the charger 1 to the registration destination.

  FIG. 9 shows a processing flowchart of the processing program 210 of the mobile device 2. In FIG. 9A, it is first determined whether there is a new message (step S41). When the message processing means 21 receives a new arrival message (Yes in step S41), the process proceeds to step S51 (F). If the message processing means 21 has not received a new arrival message in step S41 (No in step S41), the process proceeds to step S42.

  In step S42, it is determined whether or not there is a message reproduction request. If the playback switch 5 is pressed and there is a message playback request (Yes in Step S42), the stored earliest machine sound is played back using the playback means 22 (Step S44), and the process returns to Step S41 (E). . In the present embodiment, the mechanical sound is reproduced using the speaker of the portable device 2, but the speaker may be provided in the charger 1 and may be reproduced by the charger 1.

  In step S43, it is determined whether or not there is a message transmission request.
