  The first label information L11 is information indicating a first function group FG1 (see FIG. 5) including three functions corresponding to the labels L101 to L103 (see FIG. 3A). The second label information L12 is information indicating a second function group FG2 (see FIG. 5) including three functions corresponding to the labels L104 to L106 (see FIG. 4A). The third label information L13 is information indicating a third function group FG3 (see FIG. 5) including two functions corresponding to the labels L107 and L108 (see FIG. 4E). The function group FG0 including the first function group FG1 to the third function group FG3 is stored in the built-in memory (or the storage unit 16) of the slave unit side control unit 13.

  The display unit 18 displays the first label information L11 in the first screen state (the output state of the basic guide image IM0 or the fourth guide image IM4). The display unit 18 displays the second label information L12 in the second screen state (the output state of the first guide image IM1). The display unit 18 displays the third label information L13 in the third screen state (the output state of the fifth guide image IM5). For example, when the display unit 18 transitions from the first screen state to the second screen state, the function corresponding to each function button 140 is also switched from the first function group FG1 to the second function group FG2. Therefore, the function corresponding to each function button 140 can be easily switched in the slave unit side control unit 13.

  Each of the display areas R <b> 1 to R <b> 4 is defined so as not to protrude to the upper area of the function button 140 adjacent to the corresponding function button 140. Specifically, the display area R2 is defined so as not to protrude to the upper area of the first function button 141 (or the third function button 143) adjacent to the corresponding second function button 142. Therefore, it becomes easier to understand the correspondence between the four function buttons 140 and the functions indicated in the label information L1. Further, the appearance of the handset 1 as a whole is also improved.

  The display areas R1 to R4 may be areas on the data that cannot be viewed or may be visible areas. The visually recognizable area may be, for example, an image area surrounded by a square frame, or an image area displayed in a color different from the surrounding colors.

  The label L100 is displayed in any one of the display areas R1 to R4 and indicates the function of the corresponding function button 140 among the four function buttons 140. When the label L100 is included in the guide image, the function indicated by the label L100 is executed by pressing the function button 140 immediately below the label L100. In other words, the four labels L100 are not always displayed in the display areas R1 to R4. For example, only the three labels L100 may be displayed in order from the left (see FIG. 3A). For example, when the label L100 is not displayed in the rightmost display region R4, no function is executed even if the fourth function button 144 is pressed.

  By the way, the subunit | mobile_unit side control part 13 has a function as the setting part 130, as shown to FIG. 2A. The setting unit 130 sets function assignments for the four function buttons 140 based on a predetermined setting input from the outside (for example, the constructor of the child device 1 or the administrator of the child device 1).

  For example, in a state where a specific guidance image is output on the display unit 18, when an administrator performs a specific operation input with a high secure level that a resident or the like does not know using the slave unit side operation unit 14 or the like, The subunit | mobile_unit side control part 13 makes the display part 18 output the guidance image for a setting. While viewing the guidance information displayed in the guidance image for setting, the administrator performs setting input regarding which function is assigned to the label L100 of which label information L1 with respect to each function button 140. If the display unit 18 is, for example, a touch panel display, a function corresponding to each label L100 is selected from a list of a plurality of types of functions displayed in the pull-down menu for each function button 140 by a touch operation with a fingertip. May be. The information input here is stored in the built-in memory (or storage unit 16) of the slave unit side control unit 13.

  That is, with respect to the same function button 140 (for example, the first function button 141), “function A” is executed in the first label information L11, “function B” in the second label information L12, and so on. Multiple functions can be set. At the stage where the handset 1 is manufactured, for example, a plurality of types of functions that can be set are registered in the built-in memory of the handset-side controller 13, and standard functions are assigned to the function buttons 140 as defaults. Assigned. The types of functions that can be set may be added after construction of the slave unit 1 through a memory card, a telecommunication line, or the like.

  As described above, since the slave unit side control unit 13 has a function as the setting unit 130, it is possible to assign a function according to the installation environment of the slave unit 1, a request, or the like.

  In addition, the setting unit 130 may be configured to set the label information L1 displayed as an image on the display screen 180 based on a specific setting input from the outside (constructor or administrator). For example, it may be possible to set which label information L1 is displayed on the basic guidance image IM0. Further, the label L100 included in the label information L1 may be changed in units of character string data. It is desirable that the setting input can be performed by the handset side operation unit 14 and a touch operation on the screen while viewing the guide information displayed on the setting guide image on the display unit 18. In this case, the label display according to the installation environment of the subunit | mobile_unit 1 or a request | requirement etc. is attained.

  By the way, in this embodiment, the four function buttons 140 are arranged below the imaging unit 11. Therefore, when the operator H1 operates the function button 140, the possibility that the operator H1's hand or the like enters the imaging region of the imaging unit 11 and the operator H1's face cannot be appropriately captured can be reduced.

(2.3) Configuration of Base Unit Next, the configuration of the base unit 2 will be described. As shown in FIG. 2A, the base unit 2 includes a base unit side transmission unit 21, a display unit 22, a base unit side control unit 23, a base unit side operation unit 24, a video processing unit 25, and a storage unit 26.

In FIG. 2A, the second trunk line 62 and the branch line 63 are shown by one line. The parent device side transmission unit 21 is configured to be capable of bidirectional communication with the child device 1 via the communication unit 32 of the control device 3. The parent device side transmission unit 21 is configured to transmit a communication signal to the child device 1. The communication signal includes an audio signal and a control signal. Moreover, the main | base station side transmission part 21 receives a communication signal transmitted from the subunit | mobile_unit 1 via the communication part 32, and acquires an audio | voice signal, a video signal, etc. by demodulating the received communication signal. The audio signal is output to the calling unit 29 via the parent device side control unit 23, and the video signal is output to the display unit 22 via the parent device side control unit 23.

  The display unit 22 is configured to display a video from the video processing unit 25 (for example, a video captured by the imaging unit 11 of the slave unit 1). The display unit 22 is a liquid crystal display, for example. When the parent device 2 includes a touch panel display, the touch panel display may serve as both the display unit 22 and the parent device side operation unit 24.

  The master unit side operation unit 24 is configured to receive an operation of a person (for example, a resident). When a predetermined operation (for example, a push operation) is performed on the parent device side operation unit 24 in a state where the parent device side transmission unit 21 receives a call signal for calling a resident, the child device 1 and the parent device 2 is in a state where a voice call is possible.

  The video processing unit 25 is configured to receive a video signal from the slave unit 1 received by the base unit side transmission unit 21 and process a video included in the video signal by signal processing. The video processing unit 25 is configured to perform, for example, a synthesis process that combines a plurality of videos. The video processing unit 25 is realized by a device such as a DSP or FPGA, for example.

  The parent device side control unit 23 is constituted by, for example, a microcomputer having a CPU and a memory as main components. The microcomputer functions as the parent device control unit 23 by the CPU executing the program stored in the memory. Here, the program executed by the CPU is recorded in advance in the memory of the microcomputer, but may be provided by being recorded on a recording medium such as a memory card, or may be provided through an electric communication line such as the Internet. .

  The parent device side control unit 23 is configured to control the parent device side transmission unit 21 and the display unit 22. Further, the parent device side control unit 23 is configured to control the video processing unit 25. The parent device side control unit 23 controls the parent device side transmission unit 21 to cause the parent device side transmission unit 21 to transmit a communication signal to the child device 1 and causes the parent device side transmission unit 21 to transmit the communication signal from the child device 1. The communication signal is received. The communication signal to the handset 1 includes an audio signal and a control signal. The communication signal from the slave unit 1 includes an audio signal, a video signal, a control signal, and the like. The parent device side control unit 23 controls the display unit 22 to display the video transmitted from the child device 1 on the display unit 22.

  The storage unit 26 includes a readable / writable memory. The storage unit 26 is a flash memory, for example. The storage unit 26 stores the video sent from the child device 1. In the present embodiment, the storage unit 26 is provided outside the parent device side control unit 23, but may be provided inside the parent device side control unit 23. That is, the storage unit 26 may be a built-in memory of the parent device side control unit 23.

  The notification unit 27 is configured to output a ringing tone, for example. When there is a call from slave unit 1, base unit side control unit 23 causes notification unit 27 to output a ringing tone at a predetermined timing. In other words, when there is a call from the child device 1, the parent device side control unit 23 causes the notification unit 27 to perform a notification operation for notifying that there is a call from the child device 1. Note that the notification unit 27 may be configured to output a voice instead of a ringing tone.

(2.4) Configuration of Control Device Next, the configuration of the control device 3 will be described. As illustrated in FIG. 2A, the control device 3 includes a signal processing unit 31 and a communication unit 32.

  The communication unit 32 is a communication interface for communicating with the child device 1 and the parent device 2. The communication unit 32 is connected to the child device 1 via the first trunk line 61. The communication unit 32 is connected to the parent device 2 via the second trunk line 62, the branch line 63, and the branching device 5. The communication unit 32 is configured to be capable of bidirectional communication with the slave unit side transmission unit 12 of the slave unit 1. The communication unit 32 is configured to be capable of bidirectional communication with the parent device side transmission unit 21 of the parent device 2. That is, the communication unit 32 is configured to relay communication between the parent device side transmission unit 21 and the child device side transmission unit 12. Therefore, the communication unit 32 relays the communication signal transmitted from the child device side transmission unit 12 of the child device 1 and transmits it to the plurality of parent devices 2. Here, the communication signal transmitted from the child device 1 includes information (for example, an address or the like) for specifying the parent device 2 as a transmission destination. For this reason, only the parent device 2 in which the address assigned to itself matches the address included in the communication signal among the plurality of parent devices 2 can receive the communication signal. The communication unit 32 relays a communication signal transmitted from each of the plurality of parent devices 2 and transmits the relayed signal to the child device 1.

  The signal processing unit 31 is configured by, for example, a microcomputer having a CPU and a memory as main components. The microcomputer functions as the signal processing unit 31 when the CPU executes a program stored in the memory. Here, the program executed by the CPU is recorded in advance in the memory of the microcomputer, but may be provided by being recorded on a recording medium such as a memory card, or may be provided through an electric communication line such as the Internet. .

  The signal processing unit 31 is configured to control the communication unit 32. Specifically, the signal processing unit 31 controls the communication unit 32 to transmit a communication signal transmitted from the child device 1 to the plurality of parent devices 2 and from each of the plurality of parent devices 2. The communication signal to be transmitted is transmitted to the slave unit 1.

(2.5) Function Button Hereinafter, the function executed by pressing the function button 140 will be described in detail with reference to the guide images IM0 to IM5 shown in FIGS. 3A to 4E. The types of functions described below are merely examples and are not particularly limited. Also, which function is assigned to which function button 140 is not particularly limited. The assignment of functions may be changed as appropriate via the setting unit 130 according to the installation environment of the intercom system 10 or a request.

  The basic guide image IM0 in FIG. 3A includes first label information L11 as label information L1. The first label information L11 includes, for example, labels L101 to L103.

  A label L101 in FIG. 3A indicates “English”. When the operator H1 presses the first function button 141 under the label L101, the Japanese character guide displayed in the guide image is switched to the English character guide (see FIG. 4A: first guide image IM1). . At this time, the function of each function button 140 is also switched from the first function group FG1 to the second function group FG2.

  4A includes second label information L12 as label information L1. The leftmost label L104 indicates “Japanese”. When the first function button 141 is pressed, the English character guide displayed in the guide image is switched to the original Japanese character guide. The function of each function button 140 is also switched from the second function group FG2 to the original first function group FG1.

  3B, when the label information L1 includes character string data having a predetermined length or more, like the “English (English)” of the label L101 in FIG. 3B, the display unit 18 displays the character string data in a plurality of rows or columns. The images may be displayed separately (in this case, two lines). In this case, even if the character string data is longer than the predetermined length, the correspondence between the four function buttons 140 and the functions indicated in the label information L1 can be easily understood. Further, the appearance of the handset 1 as a whole is also improved.

  A label L102 in FIG. 3A indicates “management room”. When the operator H1 presses the second function button 142 below the label L102, a call to the management room is started (see FIG. 4B: second guidance image IM2). In this case, the function of each function button 140 is temporarily switched to the “invalid state”. That is, in the screen state of the second guide image IM2, no function is executed regardless of which function button 140 is pressed. Regarding the call to the management room, it is not necessary to press the call button N4, or the call to the management room may be started after the call button N4 is further pressed after the second function button 142 is operated. .

  A label L103 in FIG. 3A indicates “Notice”. When the operator H1 presses the third function button 143 below the label L103, an operation process related to “notification” is started (see FIG. 4D: fourth guidance image IM4). The fourth guide image IM4 is substantially the same as the basic guide image IM0, but the guide information “Please press the room number” displayed in the upper area of the display screen 180 is, for example, “Hold the ID collation key over” Switch to the guide information "Please". However, the function of each function button 140 is maintained in the state of the first function group FG1. In the screen state of the fourth guide image IM4, for example, various services can be provided if authentication is successful by holding an ID card having an ID verification key over the ID verification unit Y1 (non-contact key reader) at the bottom of the housing X1. Transition to a guide image (not shown) on which information is displayed. This “notice” function is a function that provides service information for residents who own ID cards, not mainly for visitors. By executing this function, the resident who owns the ID card confirms the information on locking / unlocking of the dwelling entrance, the presence / absence of deliveries, the alarm occurrence status in the dwelling unit, etc. in the guidance image after the transition. be able to.

  In the state where the guidance information “please press the room number” is output as in the basic guidance image IM0 (or the first guidance image IM1), the room number is input using the number buttons N1, and the call button N4 is entered. When is pressed, a transition is made to the third guide image IM3 (see FIG. 4C). Then, a call is started to the call destination of the corresponding room number (room 1024 in the illustrated example). Also in this case, the function of each function button 140 is temporarily switched to the “invalid state”. When the third guidance image IM3 is being output, when the operator H1 blows a voice according to the guidance information “Please tell me your name, I will be the agent”, the voice data is recorded, and the master unit The contents of 2 are notified during the call.

  A fifth guide image IM5 in FIG. 4E is an image for guiding that a call is in progress. For example, in the state of the second guide image IM2 or the third guide image IM3 that is the guide image being called, when the callee resident responds with the parent device 2, the transition is made to the fifth guide image IM5. In this case, the function of each function button 140 in the invalid state is switched to the state of the third function group FG3.

  Here, two labels L107 and L108 are included in the fifth guide image IM5. A label L107 indicates “low volume”. A label L108 indicates “high volume”. The label L107 is displayed in the display area R3, and the label L108 is displayed in the display area R4. When the third function button 143 below the label L107 or the fourth function button 144 below the label L108 is pressed, the reception volume of the handset 1 during a call is changed. In short, the reception volume decreases every time the third function button 143 is pressed, and conversely, the reception volume increases every time the fourth function button 144 is pressed. Note that the label L100 is not displayed in the display areas R1 and R2, and no function is executed even if the first function button 141 and the second function button 142 are pressed.

  When the call with the parent device 2 ends, the fifth guide image IM5 changes to the original basic guide image IM0, and the function of each function button 140 switches from the third function group FG3 to the first function group FG1.

  As described above, in the present embodiment, the four function buttons 140 are provided, so that the operator H1 can directly execute a function assigned in advance to each function button 140. In addition, since the function corresponding to one function button 140 also changes according to the label information L1 displayed on the display screen 180, more functions than the number of function buttons 140 can be added to the slave unit 1. Therefore, the convenience can be improved.

(3) Modifications The above embodiment is only one of various embodiments of the present disclosure. The above embodiment can be variously modified according to the design and the like as long as the object of the present disclosure can be achieved. Further, the same function as the slave unit side control unit 13 according to the above embodiment is embodied by a control method of the intercom entrance device (slave unit 1), a computer program, or a non-temporary recording medium storing the computer program. May be.

  Hereinafter, modifications of the embodiment will be listed. The modifications described below can be applied in appropriate combinations. Hereinafter, the above embodiment may be referred to as a “basic example”.

  The subunit | mobile_unit 1 in this indication contains the computer system in the subunit | mobile_unit side control part 13 grade | etc., For example. The computer system mainly includes a processor and a memory as hardware. When the processor executes the program recorded in the memory of the computer system, the function as the slave unit side control unit 13 in the present disclosure is realized. The program may be recorded in advance in a memory of a computer system, may be provided through a telecommunication line, or recorded in a non-transitory recording medium such as a memory card, an optical disk, or a hard disk drive that can be read by the computer system. May be provided. A processor of a computer system includes one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The plurality of electronic circuits may be integrated on one chip, or may be distributed on a plurality of chips. The plurality of chips may be integrated into one device, or may be distributed and provided in a plurality of devices.

  In addition, it is not an essential configuration for the slave unit 1 that a plurality of functions in the slave unit 1 are integrated into one casing X1, and the constituent elements of the slave unit 1 are distributed and provided in a plurality of casings. It may be done. Furthermore, at least some of the functions of the child device 1 such as the child device side control unit 13 may be realized by, for example, cloud (cloud computing). On the contrary, all the functions of the subunit | mobile_unit 1 may be integrated to one housing | casing X1 like the said embodiment.

(3.1) Modification 1
When the slave unit 1 is configured to communicate with the master unit 2 across a plurality of buildings via the control device 3, in the basic example, a call is made by combining the numeric button N1 and the asterisk button N2. Has been done. When calling the main unit 2 in the 1024 room of the first building, “1 * 1024” is input.

  In this modification, a function capable of selecting “building” is assigned to the function of the function button 140. 6A to 6C are schematic views of guide images in the present modification.

  When the display unit 18 of the present modification displays the specific label information L1 as an image, at least one of the plurality of function buttons 140 includes a plurality of call target groups G1 each including one or a plurality of call destinations. A function to select a specific call target group G1. The “call target group G1” referred to here corresponds to a “building” including a plurality of call destinations (master 2). However, the “call target group G1” may correspond to, for example, a management room or a multipurpose room as long as there is one call destination (master unit 2).

  FIG. 6A shows a sixth guide image IM6 of this modification. The sixth guide image IM6 corresponds to the basic guide screen IM0 of the basic example, and when the display unit 18 detects a person such as a visitor by the sensor 17, the output of the sixth guide image IM6 is started. In the upper area of the display screen 180, guidance information “Please select a building number” is output. In the sixth guide image IM6, a function capable of selecting a ridge is assigned to the first function button 141 and the second function button 142. In this modification, it is assumed that the label information L1 includes fourth label information L14 and fifth label information L15. The fourth label information L14 is label information of the sixth guide image IM6 (see FIG. 6A). The fifth label information L15 is label information of the eighth guide image IM8 (see FIG. 6C).

  The fourth label information L14 includes, for example, labels L109 to L111.

  A label L109 indicates “first building”. When the operator H1 presses the first function button 141 below the label L109, inputs the room number and presses the call button N4, the seventh guide image IM7 (see FIG. 6B) for guiding that the call is being performed. ). Then, a call is started to the 1024 room of the first building.

  The label L110 indicates “second building”. When the operator H1 presses the second function button 142 under the label L110, inputs the room number and presses the call button N4, the call is started for the corresponding room number of the second building.

  A label L111 indicates “Notice”. Since the function when the third function button 143 under the label L111 is pressed is the same as the function corresponding to the label L103 of the basic example, the description is omitted here.

  By the way, when the operator H1 presses the asterisk button N2 that is the auxiliary button P1 and then presses the call button N4 in the screen state of the sixth guide image IM6, for example, the eighth guide image IM8 (see FIG. 6C). ).

  The fifth label information L15 includes, for example, labels L112 to L115. Labels L112 to L114 respectively indicate “kids room”, “meeting room”, and “guest room”. A label L115 indicates “management room”. In short, the operator H1 can switch the selectable call target group G1 to another call target group G1 through the auxiliary button P1.

  When the operator H1 presses the function button 140 under any one of the labels L112 to L115, a call is started to the parent device 2 installed in the corresponding multipurpose room or management room.

  According to this configuration, the “building” can be selected by the function button 140, and the convenience is further improved. Moreover, even when the number of the call target groups G1 exceeds the number of the function buttons 140, the possibility that the convenience is lowered can be reduced by the auxiliary buttons.

  Note that names such as “first building”, “second building”, and “kids room” shown on the label L100 may be appropriately changed by the setting unit 130 described in the basic example. For example, “first building” and “second building” may be changed to “west building”, “east building”, and the like.

(3.2) Modification 2
In the first modification, the selectable call target group G1 is switched to another call target group G1 through the operation of the auxiliary button P1. However, this switching may also be assigned as a function of the function button 140.

  In the present modification, at least one of the four function buttons 140 has a function of transitioning the display image (guide image) so that the label information L1 currently displayed on the display unit 18 is displayed with another label information L1. Have 7A and 7B are schematic views of guide images in the present modification.

  FIG. 7A shows a ninth guide image IM9 of this modification. The ninth guidance image IM9 corresponds to the basic guidance screen IM0 of the basic example, and when the display unit 18 detects a person such as a visitor by the sensor 17, the ninth guidance image IM9 starts outputting the ninth guidance image IM9. In the upper area of the display screen 180, guidance information “Please select a building number” is output. In the ninth guide image IM9, functions capable of selecting a ridge are assigned to the first to third function buttons 141 to 143. In addition, a function for transitioning the display image is assigned to the fourth function button 144.

  In this modification, it is assumed that the label information L1 includes sixth label information L16 and seventh label information L17. The sixth label information L16 is label information of the ninth guide image IM9 (see FIG. 7A). The seventh label information L17 is label information of the tenth guide image IM10 (see FIG. 7B).

  The sixth label information L16 includes, for example, four labels L116 to L119. Labels L116 to L119 respectively indicate “first building”, “second building”, “third building”, and “next”. When the operator H1 presses the function button 140 below any of the labels L116 to L118 in the screen state of the ninth guide image IM9, inputs the room number and presses the call button N4, the corresponding building A call is initiated for the room number. On the other hand, when the operator H1 presses the fourth function button 144 under the label L119 in the screen state of the ninth guidance image IM9, the transition is made from the ninth guidance image IM9 to the tenth guidance image IM10 (see FIG. 7B). .

  The tenth guide image IM10 includes, for example, four labels L120 to L123. Labels L120 to L123 indicate “fourth building”, “fifth building”, “sixth building”, and “notice”, respectively.

  According to this configuration, the fourth function button 144 has a function of transitioning the display image so that the label information L16 currently displayed is displayed with another label information L17. Therefore, more functions than the number of function buttons 140 can be added, and even in such a case, the possibility that convenience may be reduced can be reduced.

  In particular, in the present modification, the fourth function button 144 has a function of switching the call target group G1 that can be selected from the plurality of call target groups G1. That is, the operator H1 switches the three selectable call target groups G1 (first building to third building) to another three selectable call target groups G1 (fourth building to sixth building). Can do. Therefore, even when the number of call target groups G1 exceeds the number of function buttons 140, the possibility that convenience may be reduced can be reduced.

(3.3) Other Modifications In the basic example, the function button 140 is provided separately from the display unit 18 as the operation member M1 that can be mechanically pushed backward. However, when the display unit 18 includes a touch panel display, the function buttons 140 may be displayed on the display screen 180 as an image. For example, a button-shaped image corresponding to the function button 140 may be output below each of the display areas R1 to R4. The operator H1 may execute various functions corresponding to the function buttons 140 output on the display screen 180 by performing a touch operation.

  When the display unit 18 includes a touch panel display, the buttons N1 to N4 other than the function buttons 140 may be displayed on the display screen 180 as images. In other words, the room number may be input, the call is confirmed, the call is canceled, and the like by a touch operation on the screen. In short, the touch panel display may serve as both the display unit 18 and the slave unit side operation unit 14.

  In the basic example, the number of function buttons 140 is four, but the number is not particularly limited as long as it is two or more.

  In the second modification, the function button 140 is assigned a function for transitioning the display image, which corresponds to “next” of the label L119.
