  The main functions of the constituent units 11 to 13 and 41 to 48 constituting the interphone slave device 10 and the interphone master device 40 will be described. First, in the intercom handset 10, the light receiving unit 11 receives an infrared communication signal emitted by the mobile phone terminal 20 of the visitor. The display unit 12 is a display panel such as a liquid crystal or an EL, and displays various messages. The doorbell 13 is a button (or switch) provided on a general intercom. When the visitor presses the finger with a finger, the visitor 13 is informed of the visitor to the resident through the interphone master unit 40. .

  Next, in the intercom base unit 40, the control unit 41 controls the operation of the entire intercom apparatus. The search unit 42 receives information such as the telephone number of the visitor's mobile phone terminal 20 from the control unit 41, and searches the data in the internal database 43 including the visitor information that the resident has previously input. The display unit 44 is a display panel having the same configuration and function as the display unit 12 of the intercom slave device 10 described above. The storage unit 45 is, for example, a readable / writable semiconductor memory for storing information sent from the control unit 41, such as visit date / time of a visitor, mobile phone number, and the like. For example, in the case of a specific visitor who is expected to visit, the mail function unit 46 reports the visit of the visitor to the outdoor mobile phone terminal 50 via the telephone line 30 or the like. The mail transmission setting unit 47 is a switch for turning on / off the mail function 46. For example, when a resident goes out, the mail transmission setting unit 47 is set to ON. The speaker unit 48 is means for making a call with a visitor who has pressed the doorbell 13.

  Next, the operation of the intercom apparatus according to the present invention shown in FIGS. 1 and 2 will be described with reference to the flowcharts of FIGS. FIG. 3 shows a “telephone number acquisition routine”. FIG. 4 shows a “telephone number search routine”. FIG. 5 is a “telephone number search # 2 routine”. FIG. 6 is a “business mail acquisition routine”. FIG. 7 shows a “mail transmission routine”.

  First, the “phone number acquisition routine”, that is, the operation until acquiring the telephone number of the mobile phone terminal 20 of the visitor will be described with reference to FIG. A visitor depresses the doorbell 13 of the intercom handset 10 (step A1). Then, as usual, a ringing tone sounds from the speaker unit 48 of the receiving-side interphone master unit 40 to notify that there is a visitor when at home. In addition, when the doorbell 13 is pressed by the visitor, the control unit 41 is powered on (step A2). In this way, in a normal state where there are no visitors, the control unit 41 is put in a standby state by turning off the power supply of the control unit 41, and wasteful power consumption is suppressed. When the control unit 41 is activated, the control unit 41 sends a signal to the intercom handset 10 and displays a message such as “Please send the phone number of the mobile phone terminal 20 by infrared communication” on the display unit 12. The message is displayed and the visitor is prompted to perform infrared communication of his / her mobile phone number to the intercom handset 10 (step A3).

  Therefore, the visitor transmits the telephone number of the mobile phone terminal 20 from the mobile phone terminal 20 to the interphone handset 10 by infrared communication. Ir (infrared communication) data transmitted from the visitor's mobile phone terminal 20 is received by the light receiving unit 11 and demodulated by the control unit 41 of the intercom base unit 40. And it is judged whether the telephone number of the visitor's mobile telephone terminal 20 was acquired normally (step A4). If not normally acquired (step A4: N), the process returns to the above-described step A3 to prompt the transmission again. On the other hand, when it is acquired normally (step A4: Y), the telephone number is stored in the storage unit 45 and transmitted to the search unit 42 (step A5). This completes the operation of the “telephone number acquisition routine”, and executes the “telephone number search routine” B0 described later with reference to FIG.

  Next, with reference to the flowchart of FIG. 4, the “telephone number search routine” B0, that is, the operation until the telephone number of the mobile phone terminal 20 of the visitor is acquired and the visitor is identified from this telephone number will be described. The control unit 41 that has acquired the telephone number transmits the telephone number to the search unit 42 in order to determine a visitor from the telephone number acquired in the “phone number acquisition routine”. The search unit 42 accesses the internal database 43 built in the intercom base unit 40, that is, the telephone directory database 43 previously created by the resident (step B1). Then, the acquired telephone number is searched, and it is determined whether or not a telephone number that matches the acquired telephone number exists in the internal database 43 (step B2).

  If there is a telephone number that matches the acquired telephone number in the internal database 43 in step B2 described above (step B2: Y), the search unit 42 acquires the telephone directory information that is the registration source of the telephone number. (Step B3), and returns the signal to the control unit 41. Upon receiving this signal, the control unit 41 first saves this signal in the storage unit 45. Next, the signal is transmitted to the display unit 44 of the intercom base unit 40, and the telephone book information of the visitor is displayed on the display unit 45 of the intercom base unit 40 (step B4). Next, it is determined whether or not the switch of the mail transmission setting unit 47 is ON (step B5). When the switch of the mail transmission setting unit 47 is in the ON state (step B5: Y), the process proceeds to a “mail transmission routine” E0 described later with reference to the flowchart of FIG. On the other hand, when the switch of the mail transmission setting unit 47 is not ON (step B5: N), this operation is terminated.

  On the other hand, in step B2, if there is no telephone number that matches the acquired telephone number in the internal database 43 (step B2: N), the “phone number search # 2 routine described with reference to the flowchart of FIG. “Transition to C0.

  Next, the “phone number search # 2 routine” C0 will be described with reference to the flowchart of FIG. This “telephone number search # 2 routine” C0 is an operation in which the search unit 42 searches for a telephone number by external access. When the search result of the internal database 43 is NG (step B2: N), the search unit 42 accesses the external database 31 using the telephone line 30 (step C1). Then, the search unit 42 searches for a telephone number that matches the telephone number obtained from the telephone directory of the content providing the telephone number search service, that is, the external database 31 (step C2).

  As a result of searching from the external database 31, if the same telephone number as the telephone number acquired from the visitor exists (step C2: Y), the search unit 42 will search for the company name or name where the telephone number is registered. A signal including the telephone book information is acquired and returned to the control unit 41 (step C3). Upon receiving this signal, the control unit 41 first stores this signal in the storage unit 45. Next, the signal is transmitted to the display unit 44, and the phone book information of the visitor's company name or name is displayed on the display unit 44 of the intercom master unit 40 (step C4).

  Next, it is determined whether or not the SW of the mail transmission setting unit 47 is ON (step C5). When the switch (SW) of the mail transmission setting unit 47 is ON (step C5: Y), the process proceeds to a “mail transmission routine” E0 described later with reference to FIG. On the other hand, when the SW of the mail transmission setting unit 47 is not ON (step C5: N), the operation is terminated. Further, when the same telephone number does not exist in the external database 31 in the above-described step C2 (step C2: N), the process proceeds to a “message mail acquisition routine” D0 described later with reference to FIG.

  Next, with reference to the flowchart of FIG. 6, the “message mail acquisition routine”, that is, the operation when the visitor cannot be identified even after connecting to the external database 31 will be described. This operation is an operation of requesting a visitor to create a message by e-mail and acquiring the message e-mail. The search unit 42 that is the search result NG in the external database 31 transmits a signal of the search result NG to the control unit 41 (step D1). Receiving this signal, the control unit 41 transmits and displays a message signal “Create a message by e-mail and make infrared communication” on the display unit 12 of the intercom 10. Receiving this signal, the intercom handset 10 displays the above message on the display unit 12 to create a message for the visitor and inform the visitor to perform infrared communication (step D2).

  Accordingly, the visitor creates an email with the contents of the message using the mobile phone terminal 20. Then, the Ir data transmitted by infrared communication is received by the light receiving unit 11 (step D3). The Ir data is transmitted to the control unit 41, and the control unit 41 that has received the Ir data demodulates the data and extracts a message mail, and stores a signal including information on the telephone number and the message mail in the storage unit 45. And displayed on the display unit 44 (step D4).

  And it is judged whether SW of the mail transmission setting part 47 is ON (step D5). When the SW of the mail transmission setting unit 47 is ON (step D5: Y), the process proceeds to a “mail transmission routine” E0 described later with reference to the flowchart of FIG. On the other hand, if the SW of the mail transmission setting unit 47 is not ON (step D5: N), the operation is terminated.

  Next, the “mail transmission routine” E0 will be described with reference to the flowchart of FIG. First, the signal transmitted from the control unit 41 to the display unit 44 is transmitted to the mail function unit (or mail transmission means) 46 (step E1). Then, the mail function unit 46 accesses the outside using the telephone line 30 (step E2). Finally, the mail function unit 46 transmits the signal transmitted from the control unit 41 to the mobile phone terminal 50 of the resident (Step E3), and ends the operation. As a result, the resident confirms the visitor's telephone number and the contents of the e-mail (message) by e-mail.
