That is, the communication control device 5 connects the parent machine 2 and the child machine 1 of the household A1 called by the visitor B1, and relays communication (call) between the two. Hereinafter, the operation of the walkie-talkie system 100 of the present embodiment will be described with reference to Figs. 2 to 5 . In the following, unless otherwise specified, the main body of the operation will be described as the slave unit 1 (or the master unit 2). However, the first control unit 11 of the slave unit 1 (or the second control unit 21 of the parent unit 2) is actually used. ) as the main body. For example, "the slave 1 shoots the visitor B1" means that "the first control unit 11 of the slave 1 captures the visitor B1 by controlling the imaging device 121 via the first video processing unit 12". As shown in FIG. 2, first, when the child machine 1 detects the visitor B1 by, for example, a built-in human body sensor, the visitor B1 is photographed (step S101). Further, the slave unit 1 may be configured to capture the visitor B1 when, for example, the first operation unit 15 accepts an input. Next, the child machine 1 is displayed on the first display unit 13 using the first screen for inputting the room number of the respondent (step S102). Further, the child machine 1 accepts the input of the room number of the visitor B1 on the first screen (step S103). As shown in FIG. 3A, the first display area 131, the second display area 132, and the third display area 133 are displayed on the first screen of the first display unit 13. The first display region 131 is a circular region located above the first display portion 13 . The image (still image) of the photographed visitor B1 is displayed in the first display area 131. The second display area 132 is an area located on the lower side of the first display area 131. In the second display area 132, the message "Please enter the number of the respondent's room" is displayed, and the message that prompts the visitor B1 to input the room number and the room number input by the visitor B1. In FIG. 3A, since the visitor B1 has not yet entered the room number, the room number is not displayed in the second display area 132. Further, in the second display area 132, an animation in which a plurality of circular shapes are moved like a liquid with time passage is displayed. Further, whether or not the animation system is displayed in the second display area 132 is arbitrary. The third display area 133 is an area located on the lower side of the second display area 132. A so-called telephone type numeric key 151 is displayed in the third display area 133. In the present embodiment, the first operation unit 15 and the first display unit 13 constitute a touch panel. That is, the third display area 133 is also the first operation unit 15. Therefore, when the visitor B1 presses the numeric key 151, the first operation unit 15 accepts the input of the room number. Further, the visitor B1 inputs the room number of the resident A1 of the respondent by pressing the number key 151. At this time, as shown in FIG. 3B, the input room number is displayed on the second display area 132. Next, as shown in FIG. 2, the child machine 1 is displayed on the first display unit 13 using the second screen for inputting the prior information (step S104). Further, the child machine 1 accepts the input of the prior information of the visitor B1 on the second screen (step S105). As shown in FIG. 4A, the first display area 131, the second display area 132, the third display area 133, and the fourth display area 134 are displayed on the second screen of the first display unit 13. The image of the visited visitor B1 is displayed in the first display area 131 in the same manner as the first screen. In the second display area 132, a message such as "please select a cause" and the like, which prompts the visitor B1 to input the prior information, and the pre-information input by the visitor B1 (here, the relationship with the occupant, the cause) are displayed. In the present embodiment, the visitor B1 can also input the prior information by voice using the first microphone 141. Therefore, the message "Please press and hold the microphone button and speak" is also displayed in the second display area 132. The fourth display area 134 is an area located on the left side of the first display area 131. The room number input by the visitor B1 is displayed in the fourth display area 134. Here, the child machine 1 can output the sound data for prompting the visitor B1 to input the prior information from the first speaker 142, thereby prompting the visitor B1 to input the prior information by voice. In other words, the slave unit 1 may perform at least one of displaying the message prompting the input of the prior information and outputting the voice prompting the input of the prior information. Moreover, the child machine 1 can also prompt the visitor B1 to input the prior information before the visitor B1 inputs the room number (that is, before executing step S102 (refer to FIG. 2). In the third display area 133, a plurality of (here, five) selection buttons 152 and a microphone button 153 for sound input are displayed instead of the numeric keys 151. Any one of the plurality of selection buttons 152 and the microphone button 153 has a circular shape. The plurality of selection buttons 152 respectively display characters indicating the attributes of the visitor B1 such as "friends", "couriers", and "others". Therefore, the visitor B1 presses any one of the plurality of selection buttons 152, and the first operation unit 15 (that is, the input unit 3) accepts the input of the attribute of the visitor B1 (that is, the prior information). Here, the first operation unit 15 may be configured to accept, for example, the input of the name of the visitor B1 as the attribute of the visitor B1. In this case, the first display unit 13 only needs to display the software keyboard in the third display area 133. Further, the visitor B1 presses the microphone button 153 to speak to the first microphone 141, and the first microphone 141 (that is, the input unit 3) receives the input of the prior information. For example, if the visitor B1 is a courier, the visitor B1 can input the voice "I am a ○○ courier company and have your goods delivered." In FIG. 4A, the illustration of the first microphone 141 is omitted. Here, the visitor B1 inputs the advance information by pressing the selection button 152 displayed as "Express" in the plurality of selection buttons 152. At this time, as shown in FIG. 4B, the attribute of the input visitor B1 (that is, the prior information) is displayed on the second display area 132. When the visitor B1 completes the input of the prior information, the child machine 1 performs a call to the occupant of the resident A1 designated by the visitor B1. That is, as shown in FIG. 2, the child machine 1 transmits a call signal including the advance information to the parent machine 2 (step S106). At this time, the child machine 1 transmits a video signal including the image of the visitor B1 to the parent machine 2 together with the call signal. Further, the child machine 1 can display, for example, an animation indicating that the occupant is calling on the first display unit 13. Of course, the slave unit 1 can also be configured to perform a call of the occupant by the visitor B1 operating the call button after inputting the prior information. In this case, in addition to the plurality of selection buttons 152 and the microphone button 153 in the third display area 133, the call button is also displayed. Further, the first display unit 13 may be configured not to display the call button until the input of the prior information is completed, and display the call button after the completion of the input of the prior information. In this configuration, since the call of the occupant cannot be made before the visitor B1 inputs the prior information, the visitor B1 can be more surely prompted to input the prior information. As shown in FIG. 2, the parent machine 2 sounds the calling tone, and causes the light-emitting unit 27 to emit light, thereby notifying the occupant of the intention of calling (step S107). The light-emitting unit 27 emits light in a light-emitting color corresponding to the content of the prior information transmitted from the slave unit 1. For example, when the attribute of the visitor B1 indicated by the prior information is "friend", the light-emitting portion 27 emits blue. Further, for example, if the attribute of the visitor B1 indicated by the prior information is "Express", the light-emitting portion 27 emits green. Further, the parent machine 2 outputs the prior information transmitted from the slave unit 1 (step S108). In other words, the second control unit (control unit) 21 of the parent machine 2 outputs the prior information from the output unit 4 before starting the conversation with the visitor B1 via the slave unit 1. When the prior information is the text data, the parent machine 2 causes the text data to be displayed on the second display unit 23 (output unit 4). Further, when the prior information is the voice data, the parent machine 2 outputs the voice data from the second speaker 242 (output unit 4). At this time, the parent machine 2 also displays the image of the visitor B1 transmitted from the slave unit 1 on the second display unit 23. Here, if the prior information is the voice data, the parent machine 2 alternately repeats the output of the voice data and the ringing of the calling sound as described later until the input of the occupant to the second operation unit 25 is accepted. Further, when the parent machine 2 includes both the sound data and the text data, the parent machine 2 can output both the sound data from the second speaker 242 and the text data on the second display unit 23. Further, when the prior information is the sound data, the parent machine 2 can also output the sound data from the second speaker 242, convert the sound data into text data, and display the converted text data on the second display unit 23. Further, when the prior information is the text data, the parent machine 2 can also display the text data on the second display unit 23, convert the text data into sound data, and output the converted sound data from the second speaker 242. In the example shown in FIG. 5, the first display area 231 and the second display area 232 are displayed on the second display unit 23 of the parent machine 2. The image of the visitor B1 captured by the imaging device 121 is displayed in the first display area 231. The second display area 232 is an area located at a lower portion of the first display area 231. The "Express" string is displayed as the prior information in the second display area 232. Further, the parent machine 2 can display the text information of the prior information on, for example, the display area at the corner of the first display area 231 (so-called sub-screen). In this case, in the first display area 231, the text information of the prior information is displayed on the sub screen, and the image of the visitor B1 is displayed on the display area other than the sub screen. In addition, the second display area 232 is not required in this case. At this time, as shown in FIG. 2, the parent machine 2 accepts the input of the occupant to the second operation unit 25 (step S109). The occupant confirms the prior information on the call, thereby selecting the next action in the case of grasping the attributes of the visitor B1. Here, since the visitor B1 is a courier, the occupant confirms the image of the visitor B1 displayed on the second display unit 23 and the attribute "the courier" of the visitor B1, thereby confirming whether the visitor B1 is a known courier. personnel. Next, if the occupant judges that the visitor B1 is a known courier, the operation of unlocking the electric lock of the shared porch gate is not required to make a call with the visitor B1. Next, as shown in FIG. 2, the second control unit (control unit) 21 unlocks the electric lock of the shared entrance gate (step S110). Moreover, when the occupant cannot judge whether the visitor B1 is a known courier, the operation of answering the call can be performed, and the attribute of the visitor B1 is confirmed by the call. Here, in the previous walkie-talkie system, if there is a call from the slave 1 to the occupant, the first occupant must make a voice to talk with the visitor B1, thereby confirming the attribute of the visitor B1. Therefore, the personal information of the occupants (such as gender and age) is unintentionally leaked to the visitor B1 or the third party around by the voice of the occupant. Further, in the previous walkie-talkie system, some are configured to display the image of the visitor B1 on the parent machine 2 when receiving a call from the slave 1 to the occupant. In this configuration, there is a possibility that the occupant only watches the image of the visitor B1 and cannot grasp the attribute of the visitor B1, and therefore pretends not to be at home due to the alert. On the other hand, in the walkie-talkie system 100 of the present embodiment, the walkie-talkie unit 1 includes the input unit 3 (the first operation unit 15 and the first microphone 141) that inputs the prior information. The second control unit (control unit) 21 of the walkie-talkie machine 2 is configured to input the advance information input from the input unit 3 from the output unit 4 (the second display unit 23, the second) before starting the conversation with the visitor B1. Speaker 242) output. Therefore, in the walkie-talkie system 100 of the present embodiment, the occupant can grasp the attribute of the visitor B1 without having to talk to the visitor B1. That is, in the walkie-talkie system 100 of the present embodiment, the information from the visitor B1 is given to the occupant before the occupant gives the information to the visitor B1. Therefore, in the walkie-talkie system 100 of the present embodiment, the occupant can unlock the electric lock of the gate of the shared entrance without having to sound to the visitor B1 or the third party. That is, the walkie-talkie system 100 of the present embodiment is not easy for the personal information of the occupant to be inadvertently known to a third party. Further, in the walkie-talkie system 100 of the present embodiment, the occupant can more easily grasp the attribute (especially the cause) of the visitor B1 than the case where the image of the visitor B1 is only judged, and the warning is lowered. Pretend not to be at home. Furthermore, in the walkie-talkie system 100 of the present embodiment, the visitor B1 must input the advance information to the input unit 3 of the slave unit 1. Therefore, in the walkie-talkie system 100 of the present embodiment, the input unit 3 is provided to suppress the suspicious person who calls only to listen to the occupant's voice to confirm the occupant's attributes (for example, gender and age). Further, in the walkie-talkie system 100 of the present embodiment, the second control unit (control unit) 21 simultaneously outputs the advance information from the output unit 4 to the occupant who calls the resident A1 from the walkie-talkie slave unit 1. Therefore, the occupant can immediately grasp the attributes of the visitor B1 by confirming the prior information. Of course, the timing of outputting the prior information from the output unit 4 may be before the call or after the call. Further, in the walkie-talkie system 100 of the present embodiment, the walkie-talkie machine 2 may be provided with an operation unit that accepts an operation input for playing the advance information. The operation unit is constituted by, for example, a part of the second operation unit 25. Further, the second control unit (control unit) 21 may be configured to output the prior information from the output unit 4 when the operation unit receives the operation input. In this configuration, since it is necessary for the occupant to operate the operation unit to start playing the pre-existing information, the discomfort of the occupant due to the continuous playback of the prior information during the call is reduced. Further, in the walkie-talkie system 100 of the present embodiment, the walkie-talkie machine 2 includes a storage unit 211 and a play unit 251. The memory unit 211 memorizes the history of the prior information. The playback unit 251 receives a play input for playing back information of the pre-memory stored in the storage unit 211. Further, the second control unit (control unit) 21 is configured to output the prior information stored in the storage unit 211 from the output unit 4 when the playback unit 251 accepts the playback input. In this configuration, the occupant can grasp, for example, what kind of visitor B1 has come during the outing. Further, whether or not the walkie-talkie machine 2 is provided with the storage unit 211 and the playback unit 251 is arbitrary. Further, in the walkie-talkie system 100 of the present embodiment, the input unit 3 includes a plurality of selection buttons 152 corresponding to the contents of the prior information. Further, the first communication unit (communication unit) 16 is configured to transmit, to the intercom base unit 2, pre-information corresponding to the selection button 152 operated by the input unit 3 among the plurality of selection buttons 152. In this configuration, the visitor B1 can input the prior information with a simple operation. Further, whether or not the input unit 3 is provided with the selection button 152 is arbitrary. For example, the input unit 3 may be configured to input advance information only by voice. Further, in the walkie-talkie system 100 of the present embodiment, the walkie-talkie machine 2 includes a light-emitting portion 27 that emits light in at least one of a plurality of types of light-emitting colors. Further, the second control unit (control unit) 21 is configured to cause the light-emitting unit 27 to emit light in a plurality of kinds of light-emitting colors corresponding to the content of the prior information. In this configuration, the occupant can check the attribute of the visitor B1 at a position away from the walkie-talkie machine 2 by observing the illuminating color of the light-emitting unit 27. Further, whether or not the walkie-talkie machine 2 is provided with the light-emitting unit 27 is arbitrary. However, in the walkie-talkie system 100 of the present embodiment, whether or not the walkie-talkie handset 1 is provided with the imaging device 121 is arbitrary. For example, when the interphone unit 1 does not include the imaging device 121, the input unit 3 preferably inputs the pre-information by voice. That is, in this configuration, the occupant can judge whether or not the sound is familiar by listening to the voice of the visitor B1. Therefore, even if there is no image of the visitor B1, the occupant can grasp the attribute of the visitor B1. Further, in the walkie-talkie system 100 of the present embodiment, the second control unit (control unit) 21 converts the text data into mechanical sound data when the prior information is the text data, and converts the converted sound data from the first 2 speaker 242 (output unit 4) is output. Further, when the prior information is the sound data, the second control unit (control unit) 21 can convert the sound data into the text data by the voice recognition, and display the converted text data on the second display unit 23 (output Department 4). Further, in the interphone system 100 of the present embodiment, the second display unit 23 (output unit 4) may be configured to emit light in accordance with the content of the prior information in a plurality of types of illuminating colors. For example, the second control unit (control unit) 21 causes the second display unit 23 to emit light before starting the communication with the visitor B1 via the child machine 1, thereby outputting the prior information from the second display unit 23. Similarly to the light-emitting unit 27, for example, when the attribute of the visitor B1 indicated by the prior information is "friend", the second display unit 23 emits light in blue. Further, for example, if the attribute of the visitor B1 indicated by the prior information is "Express", the second display unit 23 emits green. The second display unit 23 can emit a display device such as a liquid crystal display or an organic EL display, or can emit a solid-state light-emitting element such as a light-emitting diode. Further, even if the second display unit 23 (output unit 4) emits light and outputs the information of the prior information, the base unit 2 may include the light-emitting unit 27. Further, in the walkie-talkie system 100 of the present embodiment, the hall intercom is the intercom unit 1, but other configurations may be employed. For example, when the shared entrance does not have a hall intercom, the doorbell that is installed outside the household A1 may be the intercom unit 1. Further, the walkie-talkie system 100 of the present embodiment may be, for example, a single-family house. In this case, the walkie-talkie handset 1 is placed outside the entrance or the entrance, and the walkie-talkie master 2 is placed in the home. That is, in the walkie-talkie system 100 of the present embodiment, the walkie-talkie machine 2 may be installed in a household (or a house) as long as the walkie-talkie machine 1 is installed outside the household (or house). (Variation Example of Intercom Machine) Hereinafter, the interphone unit 1A according to a modification of the embodiment will be described. In addition to the configuration of the first display unit 13 and the first operation unit 15, the interphone unit 1A of the modified example is common to the interphone unit 1 of the embodiment. Therefore, the description of the configuration common to the interphone unit 1 of the embodiment will be omitted below. In addition, the walkie-talkie handset 1A will be simply referred to as "slave 1A" hereinafter. As shown in FIGS. 6A and 6B, the child machine 1A of the present modification includes the first operation unit 15A instead of the first operation unit 15 including a touch panel. The first operation unit 15A is composed of a so-called telephone type numeric key switch 154 and a push button switch 155. Therefore, the visitor B1 can input the room number of the resident A1 of the respondent by pressing the number key switch 154 (refer to FIG. 6A). Further, in the present variation example machine 1A, the first display unit 13 displays the fifth display area 135 as the second screen instead of the third display area 133 as shown in FIG. 6B. In the fifth display area 135, an option for selecting the attribute of the visitor B1 (here, the relationship with the occupant, the cause) is displayed. In the example shown in FIG. 6B, the display is displayed in the fifth display area 135 as "1. Friend", "2. The family and other options for the future visitor B1's attributes and numbers. Therefore, the visitor B1 can input the advance information by pressing the numeric key switch 154 corresponding to the own attribute. Further, in the child machine 1A of the present modification, the visitor B1 can call the occupant of the designated household A1 by operating the button switch 155 when the second screen is displayed. Here, it is preferable that the second display area 132 of the first display unit 13 displays a message such as "Please press the call button after selecting the cause" as shown in FIG. 6B. In this case, the visitor B1 is easy to understand that the prior information must be entered before the call can be made. (Other Modifications) In the present embodiment, the parent machine 2 can have a switching function of turning on/off the function of accepting the above-mentioned prior information input. According to this configuration, the occupant of the resident A1 can invalidate the function of inputting the prior information input when the mother machine 2 is operated. Further, the switching function may be any one of the components of the walkie-talkie system 100, and may be, for example, a management room master equipped with a management room. According to this configuration, the administrator can invalidate the function of inputting the prior information to all the households A1 by operating the management room master. In this embodiment, the prior information may further include the accompanying information as an attribute of the visitor B1. The accompanying information is, for example, more detailed information about the visitor B1. For example, when the visitor B1 is a courier, the accompanying information is the weight, size, sender, and product name of the goods delivered to the occupant by the courier. In this case, the input unit 3 may be configured to include pre-information input including the accompanying information. Further, the first communication unit (communication unit) 16 may be configured to transmit the advance information to the parent machine 2 including the attached information. In the present embodiment, the parent machine 2 may perform the pre-notification when the room number is input in step S103 (see FIG. 2) or when the input of the prior information is accepted in step S105 (see FIG. 2). The pre-notification refers to the notice used to notify the occupants of the visit of the visitor B1. In other words, the second control unit (control unit) 21 may be configured to execute a pre-notification to notify the visitor B1 of the visit before the input unit 3 accepts the input of the prior information. The pre-notification can be performed by, for example, the second control unit 21 of the parent machine 2, causing the light-emitting unit 27 to emit light in a different color from that in the case of the prior information. Further, the pre-notification can be executed by, for example, the second control unit 21 of the parent machine 2, which causes the sound having a volume lower than the calling sound and having a different tone color from the calling sound to be sounded from the second speaker 242. Of course, the second control unit 21 of the parent machine 2 can also perform both the notification of the light emission by the light-emitting unit 27 and the notification of the sound from the second speaker 242 as a pre-notification. According to the above configuration, for example, the occupant of the resident A1 of the collective house is not easily scared by the unexpected ringing call. That is, the occupant of the resident A1 of the collective residence is different from the occupant of the single-family residence, and it is difficult to hear the environmental sound generated by the visitor B1 before the visitor B1 calls the occupant (for example, the sound of stopping the vehicle such as a bicycle, etc.). Therefore, if the parent machine 2 does not perform the pre-notification, the occupant of the resident A1 of the collective house may be scared by the unexpected ringing call. On the other hand, when the parent machine 2 performs the pre-notification, the occupant of the resident A1 of the collective house is not easily noticed by the visitor B1 before the call tone is heard, so that it is not easily scared by the ringing call. In the present embodiment, the second control unit (control unit) 21 of the parent machine 2 can be configured to perform the input unit 3 of the slave unit 1 by communicating with the first communication unit (communication unit) 16 of the slave unit 1. It is used to process the input of prior information (hereinafter referred to as "accept processing"). In other words, as in the present embodiment, the acceptance processing can be executed by the child machine 1 and the parent machine 2 instead of the reception processing. Hereinafter, an example of the operation of the above configuration will be described with reference to Fig. 7 . The operation shown in FIG. 7 is basically the same as the operation shown in FIG. 2, and the same reference numerals are given to the same operations, and the description thereof is omitted. After receiving the room number input of the visitor B1 in step S103, the child machine 1 transmits an acceptance signal notifying the intention to the parent machine 2 (step S11). When receiving the reception signal, the parent machine 2 transmits to the slave unit 1 a start signal for causing the child machine 1 to start accepting the prior information input (step S112). The start signal includes, for example, a second screen material for inputting prior information. When receiving the start signal, the slave 1 displays the second screen data included in the start signal on the first display unit 13 (step S104). In addition, the start signal may also include, for example, sound data or text data for prompting the input of prior information. In this case, in step S104, if the slave device 1 includes the voice data in the received start signal, the slave 1 outputs a voice prompting the input of the prior information. Further, in step S104, if the slave device 1 includes the character data in the received start signal, a message prompting the input of the prior information is displayed. Further, each of the child machines 1 transmits an information signal including the received prior information to the parent machine 2 every time the information input of the visitor B1 is accepted (step S113). Here, the child machine 1 transmits the prior information that has been accepted as input to the parent machine 2 as separate data. Thereafter, the parent machine 2 transmits, for example, after the last information signal received from the information signal received by the slave unit 1 to the slave unit 1 to cause the slave unit 1 to end the end signal for receiving the prior information input (step S114). . When receiving the end signal, the slave 1 transmits a call signal to the parent machine 2 (step S115). The call signal may include prior information as in step S106, or may not include. In the above example, the slave unit 1 executes only the processing of displaying the second screen on the first display unit 13 with the start signal as a trigger, and the processing of transmitting the information signal to the parent machine 2 as the reception processing. That is, in this example, the parent machine 2 autonomously executes the acceptance processing. On the other hand, the slave unit 1 functions only as a repeater that relays the advance information input to the parent machine 2, and does not have a function of performing the reception processing spontaneously. According to this configuration, the processing load of the slave unit 1 can be reduced, and as a result, the resources of the slave unit 1 or the communication control device 5 can be reduced. (Method and Program) The following functions of the walkie-talkie system 100 of the present embodiment can be realized by the following control method of the walkie-talkie system 100.
