  In FIG. 7, the subunit | mobile_unit side control part 21 determines whether the proximity sensor 11 turned ON (step S41). Note that the proximity sensor 11 is turned on by electrostatically detecting the cellular phone 100 when a visitor holds the cellular phone 100 over the lens unit 13A of the CCD camera 13.

  If the proximity sensor 11 is turned on, the handset-side control unit 21 determines that the visitor's mobile phone 100 has been detected, and captures the QR code displayed on the display unit 100A of the visitor's mobile phone 100. Therefore, an image capturing process is performed on the CCD camera 13 by the image processing unit 17 (step S42).

  The subunit | mobile_unit side control part 21 performs a QR code prior recognition process with respect to the CCD camera 13, after performing the image capturing process in the image process part 17 (step S43).

  After executing the QR code pre-recognition process by the image processing unit 17, the slave unit side control unit 21 starts the QR code imaging operation from the display screen of the visitor's mobile phone 100 by the CCD camera 13 (step S44). . It is assumed that the visitor holds the QR code being displayed on the display unit 100A of his / her mobile phone 100 over the lens unit 13A of the CCD camera 13 on the handset 2 side.

  The subunit | mobile_unit side control part 21 performs QR code recognition process with respect to the image | video of QR code imaged with CCD camera 13 (step S45). The QR code recognition process is a process for determining whether or not a QR code captured from the display screen of the mobile phone 100 can be normally recognized as a QR code.

  The subunit | mobile_unit side control part 21 determines whether a QR code is recognition OK by QR code recognition processing (step S46).

  If it is determined that the QR code is recognized OK, the slave unit side control unit 21 turns on the blue LED 20A (step S47), and transmits the image of the recognized QR code to the parent unit 3. (Step S48), the processing operation is terminated.

  FIG. 8 is a flowchart showing the processing operation of the system control unit 70 in the parent device 3 related to the parent device side visitor notification processing of the present embodiment.

  In the parent side visitor notification process shown in FIG. 8, when a visitor's QR code image captured by the CCD camera 13 of the slave unit 2 is received, the QR code corresponding to this QR code is converted into a QR management information table 68. In this process, the music information corresponding to the QR code is read from the music information memory 62 and the music information is output from the speaker 51 as a sound.

  In FIG. 8, the system control unit 70 determines whether or not a video of a visitor's QR code has been received from the slave unit 2 through the external interface 54 (step S61). The system control unit 70 temporarily stores the video received from the slave unit 2 in the camera image processing memory 56 and recognizes the QR code from the video on the camera image processing memory 56 through the QR code recognition processing unit 60. .

  If the QR code image is received in step S61, the system control unit 70 determines whether the QR identification number 81 corresponding to the QR code is in the QR management information table 68 through the memory control unit 69. Determination is made (step S62).

  When the system control unit 70 determines through the memory control unit 69 that there is a QR identification number 81 corresponding to the QR code, the system control unit 70 reads the QR identification number 81 from the QR management information table 68 (step S63), and the QR identification number It is determined whether or not the expiration date information 84 corresponding to 81 is in the QR management information table 68 (step S64).

  If it is determined through the memory control unit 69 that the expiration date information 84 corresponding to the QR identification number 81 exists, the system control unit 70 determines whether or not the current date and time is within the expiration date (step S65). When the expiration date information 84 is set to “none”, it is determined that the expiration date is indefinite.

  When the system control unit 70 determines that the current date and time is within the expiration date, the system control unit 70 determines that the QR code is valid, and obtains the music information number 85 corresponding to the QR identification number 81 from the QR management information table 68. Reading (step S66), the music information corresponding to the music information number 85 is read from the music information memory 62 (step S67).
