  The subunit | mobile_unit side control part 13 is comprised by the microcomputer which mainly has CPU (Central Processing Unit) and memory, for example. The microcomputer functions as the slave unit side control unit 13 when the CPU executes 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 subunit | mobile_unit side control part 13 is comprised so that the imaging part 11 and the subunit | mobile_unit side transmission part 12 may be controlled. Furthermore, the subunit | mobile_unit side control part 13 is comprised so that the video processing part 15 and the display part 18 may be controlled.

  The subunit | mobile_unit side control part 13 controls the imaging part 11, and makes the imaging part 11 image | video. In the present embodiment, for example, when the handset-side control unit 13 detects a person such as a visitor with the sensor 17, the handset-side control unit 13 activates the image capturing unit 11 to start capturing a person. The slave-side control unit 13 controls the display unit 18 to superimpose a real-time image being captured by the imaging unit 11 on the guide image that guides the input of the room number, and outputs the superimposed image to the display screen 180 (see FIG. 3A). In addition, the slave unit side control unit 13 causes the master unit 2 to display an image captured by the imaging unit 11 while calling the master unit 2 that is the call destination C1 and during communication between the slave unit 1 and the master unit 2. Send it out.

  The slave unit side control unit 13 controls the slave unit side transmission unit 12 to cause the slave unit side transmission unit 12 to transmit a communication signal to the master unit 2 and causes the slave unit side transmission unit 12 to transmit the communication signal from the master unit 2. Receive a communication signal. The communication signal to the master unit 2 includes an audio signal, a video signal, a control signal, and the like. The communication signal from the master unit 2 includes an audio signal and a control signal.

  The subunit | mobile_unit side control part 13 controls the video process part 15, and makes the video process part 15 process the image | video contained in the video signal from the imaging part 11. FIG. The video processed by the video processing unit 15 is transmitted from the slave unit side transmission unit 12 to the master unit 2.

  The subunit | mobile_unit side control part 13 is comprised so that various functions may be performed according to the operation input received with the some push button P1. The subunit | mobile_unit side control part 13 is comprised so that the function corresponding to the said guidance image may be performed based on the relationship with the guidance image currently displayed on the display screen 180 of the display part 18. FIG. For example, when the number button N1 is operated while the guidance image for prompting the input of the room number is displayed on the display screen 180, the handset-side control unit 13 displays the input number on the display screen 180. To output. Then, when the call button N4 is operated after the room number is input, the slave unit side control unit 13 starts calling the master unit 2 that is the call destination C1.

  Moreover, the subunit | mobile_unit side control part 13 performs a predetermined function, when each function button (function key) 140 receives operation input. For example, when the leftmost function button 140 is pressed, the slave-side controller 13 switches the Japanese character guide information to the English character guide information. In addition, for example, when the second function button 140 from the left is pressed, the slave-side controller 13 directly calls the management room.

  The storage unit 16 includes a readable / writable memory. The storage unit 16 is, for example, a flash memory. The storage unit 16 stores the video imaged by the imaging unit 11. The storage unit 16 of the present embodiment is provided outside the slave unit side control unit 13, but may be provided inside the slave unit side control unit 13. That is, the storage unit 16 may be a built-in memory of the slave unit side control unit 13.

  The display unit 18 includes a display screen 180 formed of a liquid crystal touch panel display, for example. The display part 18 comprises a part of the subunit | mobile_unit side operation part 14 as above-mentioned. The display unit 18 outputs (image display) the basic guide image G0 and the first guide image G1 to the third guide image G3 as shown in FIGS. 3A to 4B under the control of the slave unit side control unit 13. The basic guidance image G0 is an image that prompts the visitor to input the callee information A1 (room number). The first guide image G1 is an image that displays (presents) each time the callee information A1 is input one digit at a time. The second guide image G2 is an image for guiding that the parent device 2 (call destination C1) corresponding to the call destination information A1 is being called. The third guide image G3 is an image for guiding that the handset 1 is in a call with the base unit 2. These guide images G0 to G3 are merely examples, and the number of types of guide images and the display contents thereof are not particularly limited.

  Here, the display unit 18 controls the second period T2 out of the first period T1 during the call of the call destination C1 and the second period T2 during the call with the call destination C1 under the control of the handset side control unit 13. The call destination information A1 is displayed with low visibility and low visibility. The low display with low visibility is, for example, a display abstracted from the first image B1 (see FIGS. 3B and 6A) of the callee information A1 displayed at the time of operation input, and is a mosaic display. That is, the display unit 18 displays the second image B2 that has been subjected to mosaic processing in the second period T2. The second image B2 has lower visibility than the unprocessed first image B1. The mosaic process may be a blur process or an inversion process. It is desirable that the mosaic process is capable of reversible conversion.

  In addition, before the second period T2, the display unit 18 switches the call destination information A1 to a low display in response to reception of a predetermined operation under the control of the slave unit side control unit 13. The predetermined operation may be a touch operation on the display unit 18 or a push operation on any one of the push buttons P1 (for example, the asterisk button N2, the erase button N3, the call button N4, or the function button 140). In the case of a push operation on the function button 140, the display unit 18 may perform guidance display so that the operator H1 knows that the function button 140 is pressed to switch to the low display. That is, the slave unit 1 performs the low display at the start of the second period T2 during the call (time t4 in FIG. 5) even if there is no operation input related to switching to the low display. Prior to the second period T2, the operator H1 can select whether to enable / disable low display. The term “before the second period T2” includes, for example, a first period T1 and a third period T3 before the call. As an example, the third period T3 is a period from the time when the operator H1 first performs an operation input to the slave unit side operation unit 14 until the time when the call button N4 for confirming the input of the call destination information A1 is pressed. .

  Further, the display unit 18 cancels the low display in response to the reception of the specified operation under the control of the slave unit side control unit 13. The prescribed operation may be a touch operation on the display unit 18 or a push operation on any one of the push buttons P1 (for example, the asterisk button N2, the erase button N3, the call button N4, or the function button 140). In the case of a push operation on the function button 140, the display unit 18 may perform guidance display so that the operator H1 can know that the low display is released by pressing the function button 140. Hereinafter, the touch operation on the display unit 18 will be described.

  As shown in FIG. 3B, the display unit 18 displays, for example, a square button-shaped operation region R1 written as “ON”. "Mosaic" is written beside the operation area R1. When the operator H1 touches the inside of the operation region R1 indicated as “ON” with the fingertip, the handset-side control unit 13 executes a switching process for lowering the call destination information A1. That is, the subunit | mobile_unit side control part 13 produces | generates 2nd image B2 which performed the mosaic process with respect to 1st image B1 currently displayed, and displays the 2nd image B2 on the display part 18. FIG. In the example shown in the figure, the operation region R1 labeled “ON” is displayed as an example when the first guide image G1 is in a screen state, but may be displayed when another guide image is in a screen state.

  In addition, the display unit 18 displays an image of the operation region R1, for example, “OFF” while displaying the second image B2 subjected to the mosaic process. When the operator H1 touches the inside of the operation area R1 indicated as “OFF” with the fingertip, the handset-side control unit 13 executes a release process for canceling the low display of the callee information A1. That is, the slave-side controller 13 restores the currently displayed second image B2 to the original first image B1 and causes the display 18 to display it.

  In this way, the display unit 18 displays the operation region R1 indicated as “ON” or “OFF” on the screen, so that the operator H1 can switch the callee information A1 to a low display at an arbitrary timing. The low display can be canceled. Therefore, convenience is improved. In the present embodiment, since the display unit 18 functions as an input interface for switching to low display and canceling low display, for example, a dedicated push button is provided around the display unit 18 or any of the existing ones. It is not necessary to assign the function to the push button P1.

  The canceling function is not an essential configuration, and the handset 1 may have only a function of switching to low display. Specifically, for example, when the display unit 18 accepts a push operation and switches to low display while displaying an operation region or guidance for switching to low display, the display unit 18 hides the operation region or guidance. Good. In this case, by disabling the low display, for example, it is possible to prevent a situation where a person other than the operator H1 who is present near the handset 1 interrupts and operates to confirm the callee information A1. it can.

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. 2, 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 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 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) Operation of Interphone System Hereinafter, the operation of the interphone system 10 will be described with reference to FIGS. 3A to 5.

  First, when the sensor 17 of the child device 1 detects a visitor at time t0 (see FIG. 5), the child device 1 activates the imaging unit 11, and the basic screen shown in FIG. 3A is displayed on the display screen 180 of the display unit 18. A guide image G0 is output. The basic guidance image G0 includes character guidance information that prompts the user to input the callee information A1 (room number). In addition, a visitor's own video is superimposed and output on the basic guidance image G0.

  Subsequently, at time t1 in FIG. 5, it is assumed that the visitor starts to input the call destination information A1 using the slave unit side operation unit 14 in accordance with the basic guide image G0 (room 1024 in the illustrated example). The time t1 is the time when the first operation input to the slave unit side operation unit 14 is performed. Here, the numeric button N1 of “1” is pressed first, but when calling directly to the management room, the function button 140 may be pressed first instead of the numeric button N1. Alternatively, if the operation area R1 labeled “ON” is displayed on the display unit 18, the operation area R1 may be pressed first.

  When the operator H1 starts to input the callee information A1, the handset 1 changes the screen display from the basic guide image G0 to the first guide image G1 shown in FIG. 3B. The display unit 18 sequentially outputs to the first guide image G1 every time the callee information A1 is input one digit at a time. Finally, when the operator H1 presses the call button N4, the input of the call destination information A1 is confirmed (time t2), and the slave unit 1 is connected to the master unit of the 1024 room, which is the call destination C1, via the control device 3. At 2, the call is started. In this illustrative example, the third period T3 is, for example, a period from time t1 to t2. In the illustrated example, the operation area R1 labeled “ON” is displayed in the first guidance image G1, but it is assumed here that the operator H1 does not touch the operation area R1 within the third period T3. If the operator H1 touches the operation area R1 before pressing the call button N4 for confirming the input of the call destination information A1, the call destination information A1 is displayed in a low level within the third period T3. .

  The subunit | mobile_unit 1 changes a screen display from the 1st guidance image G1 to the 2nd guidance image G2 shown to FIG. 4A by pushing the call button N4 at the time t2. In the second guide image G2, for example, guide information “Please wait as it is” is presented. On the other hand, in base unit 2, ringing tone output is started from time t2.

  Suppose that the operator H1 performs a touch operation on the operation region R1 represented as “ON” in the screen state of the second guide image G2 (time t3). Then, the subunit | mobile_unit 1 switches 1st image B1 of the callee information A1 currently displayed on the 2nd guidance image G2 to 2nd image B2 made low-display. After time t3, the callee information A1 is displayed as an image with low visibility. In addition, the slave unit 1 displays an operation area R1 labeled “OFF” for canceling the low display during the low display.

  Here, it is assumed that a resident in the room 1024 that is the call destination C1 responds with the parent device 2 at time t4. The subunit | mobile_unit 1 starts the telephone call with the main | base station 2, and changes a screen display from the 2nd guidance image G2 to the 3rd guidance image G3 shown to FIG. 4B. Also in the third guide image G3, the low display of the callee information A1 is continued until the call ends (time t5). In the illustrated example, for example, the first period T1 is a period from time t2 to t4, and the second period T2 is a period from time t4 to t5. In this example, the low display is already being executed at the time t4. If the low display is not being executed, the slave unit 1 switches the first image B1 to the second image B2 at the time t4. .

  As described above, in the present embodiment, the call destination information A1 is displayed with low visibility and low display, so that it is possible to reduce the possibility that the callee information A1 is known to others who are present around the handset 1. Therefore, it is possible to improve confidentiality regarding the callee information A1.

(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 the 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 essential for the slave unit 1 that a plurality of functions in the slave unit 1 are integrated into one casing, and the constituent elements of the slave unit 1 are provided in a plurality of casings. It may be. 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 into one housing | casing like the said embodiment.

(3.1) Modification 1 (not shown)
In the basic example, the callee information A1 can be displayed with low visibility and low display. However, the display part 18 of the subunit | mobile_unit 1 is good also as non-display of callee information A1 (refer FIG. 6B). In FIG. 6B, all four-digit numbers in the callee information A1 are switched to asterisk notation. Also in this case, it is preferable that the display unit 18 outputs an operation area in which the callee information A1 can be switched to non-display and non-display can be canceled in the guide image. Note that the non-display period and the low display period may be mixed. For example, the display unit 18 may display the call destination information A1 at a low level in the first period T1, and hide the call destination information A1 at the second period T2. In the example of FIG. 6B, the display unit 18 is not displayed by replacing all four digits of the callee information A1 with the asterisk notation, but does not display any symbols or the like, that is, “blank”. By doing so, it may be hidden.

  Further, the non-display of the callee information A1 may be displayed in stages other than the four-digit number being switched to non-display in a lump. For example, as shown in FIGS. 8A to 8E, each time the operator H1 inputs a single digit, an unprocessed number is displayed for a short time (for example, 1 second), and the display is not displayed instantaneously. It may be switched to. In this case, the call destination information A1 is not displayed within the third period T3.

(3.2) Modification 2 (other low display)
In the basic example, the low display is realized by mosaic display. However, the display is not limited to mosaic display as long as the display is lower in visibility than the first image B1 (see FIGS. 3B and 6A) of the callee information A1 displayed at the time of operation input.

  The low display may be, for example, a display including any one or more of the following first display, second display, and third display.

  The first display is a display smaller than the display size of the callee information A1 (see FIG. 6A) displayed at the time of operation input. FIG. 6C shows an example of the first display (third image B3). The number size (font size) of the third image B3 is smaller than the number size of the first image B1.

  The second display is a display in which at least a part of the display area of the callee information A1 displayed at the time of operation input is missing. FIG. 6D shows an example of the second display (fourth image B4). The fourth image B4 is a state in which “0” and “4” are missing from the four numbers “1024” included in the first image B1. In the second display, in addition to being omitted in units of numbers such as “0” and “4”, the numbers themselves are partially displayed such that the upper half of the numbers “0” is omitted and displayed as “U”. It may be in a missing state.

  The third display is a display that is more abstract than the callee information A1 that is displayed when an operation is input. The mosaic display of the basic example is included in the third display. 7A to 7C show examples of the third display other than the mosaic display. In the example of FIG. 7A (fifth image B5), the callee information A1 is abstracted in the display of attribute information “resident”. In the example of FIG. 7B (sixth image B6), the callee information A1 is abstracted to display attribute information “management room”. In the example of FIG. 7C (seventh image B7), the callee information A1 is abstracted into a distorted number display.

  Further, the low display may be a display in a state where the color is lighter than the number of the original first image B1 as in the eighth image B8 shown in FIG. 7D. The low display may be a display in which the color of the number of the callee information A1 is adjusted to a color close to the surrounding colors (for example, similar colors). The low display may be a blinking display as in the ninth image B9 shown in FIG. 7E. In the case of blinking display, for example, it is preferable that the disappearing period is sufficiently longer than the visible period.

  According to this configuration, it is possible to reduce the display of the call destination information A1 with a simple configuration (only image processing).

(3.3) Modification 3 (instruction from the parent device or information terminal)
In the basic example, the call destination information A1 is displayed in a low level in response to reception of a predetermined operation on the child device 1. The predetermined operation in the basic example is a touch operation on the display unit 18 or a push operation on the push button P1 (the asterisk button N2, the erase button N3, the call button N4, or the function button 140). That is, in the basic example, the slave unit 1 is configured to be able to select valid / invalid of low display (may be non-display) based on the determination of the operator H1.

  However, the subunit | mobile_unit 1 may be comprised so that the callee information A1 may be switched to low display (or non-display) by receiving the signal (for example, the instruction signal or setting signal mentioned later) from the outside.

  First, a configuration in which the parent device 2 (communication device) transmits an “instruction signal” to the child device 1 will be described with reference to FIG. In addition, about the component substantially common with the main | base station 2 of a basic example, illustration in FIG. 9 and description may be abbreviate | omitted suitably.

  As shown in FIG. 9, the base unit 2 (communication device) includes an instruction unit Y1 and an input unit Y2.

  The input unit Y2 is configured to accept an input from the outside (for example, a resident). Here, the input part Y2 is comprised by the main | base station side operation part 24 (push button) which receives the input by pushing operation from a resident, for example. However, if the display unit 22 of the parent device 2 is a touch panel type liquid crystal display, the input unit Y2 may be configured by the display unit 22 that receives an input by a touch operation or the like from a resident. Further alternatively, the input unit Y2 may be configured by a microphone that receives voice input from a resident.

  The instruction unit Y1 is configured to transmit to the child device 1 an instruction signal for switching the call destination information to low display (or non-display) in response to an input to the input unit Y2. Here, the parent device side control unit 23 further includes an instruction unit Y1. In other words, the base-side control unit 23 further has a function as the instruction unit Y1.

  On the other hand, when the slave unit side control unit 13 of the slave unit 1 receives the instruction signal from the master unit 2, the call destination information A1 of the display unit 18 is switched to low display (or non-display) according to the instruction signal. . For example, when receiving the instruction signal within the first period T1 during the call, the handset-side controller 13 immediately switches the call destination information A1 to low display (or non-display).

  The base unit 2 is preferably configured to notify the display status of the call destination information A1 in the handset 1 (for example, whether it is low display) from the display unit 22 or the like during a call (or during a call). .

  According to this configuration, the confidentiality of the callee information A1 can be improved by input from the parent device 2.

  There is a possibility that a person who operates the handset 1 may neglect or forget the act of performing a predetermined operation on the handset 1 and switching the call destination information A1 to low display (or non-display). is there. In particular, for example, children tend to be less aware of the confidentiality of the callee information A1, and if they are accustomed to operating the handset 1 on a regular basis, it is easy to neglect that action.

  On the other hand, the callee information A1 in the child device 1 can be switched from the parent device 2 to the low display (or non-display). Therefore, if a resident (for example, a parent) inputs to the input unit Y2 within the first period T1 during a call, the child who operates the handset 1 can cope with the above action. In the basic example, the low display is automatically executed at the start of the second period T2 during the call (time t4 in FIG. 5), but it is automatically set at the start of the second period T2 during the call. Even if the display is not reduced, the display can be reduced by the input to the input unit Y2 of the base unit 2.

  Next, a configuration in which the information terminal 50 (communication device) transmits an “instruction signal” to the child device 1 via the parent device 2 will be described with reference to FIG.

  Hereinafter, the information terminal 50 will be described. The information terminal 50 is a communicable portable terminal such as a mobile phone, a smartphone, or a tablet. The information terminal 50 installs dedicated application software (first communication application software) that communicates with the parent device 2 via the router 60 (see FIG. 9) in the dwelling unit E1 using short-range wireless communication. . When a resident carrying the information terminal 50 is in the house, the information terminal 50 communicates with the parent device 2 by starting the first communication application software.

  The information terminal 50 also installs dedicated application software (second communication application software) for communicating with the parent device 2 (or the control device 3) via the public network NT1, such as the Internet, the server device 250, and the router 60. is doing. When the resident carrying the information terminal 50 is outside the home, the information terminal 50 communicates with the parent device 2 (or the control device 3) by starting the second communication application software. In the master unit 2 (or the control device 3), identification information (telephone number, Mac address information, etc.) of the information terminal 50 is registered in advance. Whether the resident is in the house or out of the house, for example, the resident's presence / absence is managed by declaring the resident's absence by pressing the “absence button” provided as the operation unit 24 of the parent device 2 in advance. May be. FIG. 9 shows, as an example, communication between the information terminal 50 and the parent device 2 when a resident carrying the information terminal 50 is outside the house.

  Moreover, the subunit | mobile_unit 1 transmits a calling signal, a video signal, etc. to the information terminal 50 via the main | base station 2 in the dwelling unit E1. The subunit | mobile_unit 1 may transmit a calling signal, a video signal, etc. to the information terminal 50 via the control apparatus 3. FIG. When a resident carrying the information terminal 50 is in the house, the parent device 2 transmits a call signal to the information terminal 50 via the router 60. When the resident carrying the information terminal 50 is outside the home, the base unit 2 transmits a call signal together with the identification information to the server device 250, and the server device 250 sends a call signal to the information terminal 50 corresponding to the received identification information. Send. When the resident carrying the information terminal 50 is outside the home, the control device 3 may transmit a call signal together with the identification information to the server device 250 via a gateway connected to the public network NT1. Then, the server device 250 may transmit a call signal to the information terminal 50 corresponding to the received identification information. Therefore, if the operator H1 executes a call from the handset 1, a ringing sound is also output to the information terminal 50, and the resident can use the information terminal 50 to watch the image of the operator H1 both inside and outside the house. , Call is possible.

  Here, the information terminal 50 (communication device) includes a processing unit 51 and an input unit 52, as shown in FIG.

  The input unit 52 is configured to accept an input from the outside (for example, a resident). Here, the input part 52 is comprised by the touchscreen liquid crystal display (display part) with which the information terminal 50 is provided, for example. The input unit 52 receives an input by a touch operation or the like from a resident. The input unit 52 may be configured by a push button type operation unit provided in the information terminal 50. That is, the input unit 52 may accept an input by a push operation from a resident. Further alternatively, the input unit 52 may be configured by a microphone included in the information terminal 50. That is, the input unit 52 may accept a voice input from a resident.

  The processing unit 51 is constituted by, for example, a microcomputer having a CPU and a memory as main components. The microcomputer functions as the processing unit 51 when the CPU executes 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 processing unit 51 includes an instruction unit 510 as shown in FIG. In other words, the processing unit 51 has a function as the instruction unit 510.

  The instruction unit 510 is configured to transmit to the child device 1 an instruction signal for switching the call destination information to a low display (or non-display) in response to an input to the input unit 52. The instruction unit 510 transmits an instruction signal to the child device 1 via the router 60 and the parent device 2 when a resident carrying the information terminal 50 is in the house. When the resident who carries the information terminal 50 is outside the home, the instruction unit 510 transmits an instruction signal to the child device 1 via the public network NT1, the server device 250, the router 60, and the parent device 2. For example, when the server apparatus 250 receives an instruction signal together with the identification information of the parent device 2 from the information terminal 50, the server device 250 transmits the instruction signal to the parent device 2 of the corresponding identification information. When the resident carrying the information terminal 50 is outside the home, the instruction unit 510 may transmit an instruction signal to the child device 1 via the public network NT1, the server device 250, the gateway, and the control device 3.

  On the other hand, when the slave unit side control unit 13 of the slave unit 1 receives an instruction signal from the information terminal 50 via the master unit 2 (or the control device 3) or the like, the display unit 18 is called according to the instruction signal. The previous information A1 is switched to low display (or non-display). For example, when receiving the instruction signal within the first period T1 during the call, the handset-side controller 13 immediately switches the call destination information A1 to low display (or non-display).

  The information terminal 50 is preferably configured to notify the display status of the callee information A1 in the handset 1 (for example, whether it is low display) from the display unit or the like during a call (or during a call).

  According to this configuration, the confidentiality of the callee information A1 can be improved by an input from the information terminal 50.

  By the way, the main | base station 2 and the information terminal 50 may perform the setting regarding the low display (or non-display) of callee information A1 with respect to the subunit | mobile_unit 1 in advance. In other words, the subunit | mobile_unit 1 may be comprised so that the callee information A1 may be switched to low display (or non-display) by receiving the "setting signal" as a signal from the outside beforehand (preliminary setting). . The presetting may include, for example, settings for enabling / disabling low display. Further, the presetting may include setting for non-display validity / invalidity. The presetting may include a setting related to selection of low display or non-display.

  The base unit 2 is configured to display a setting screen on the display unit 22 by receiving a specific operation, and to receive a pre-setting through a touch operation on the setting screen from a resident or the like. Further, the information terminal 50 is configured to display a setting screen on the display unit by receiving a specific operation, and to receive a pre-setting through a touch operation on the setting screen from a resident or the like. When the parent device 2 and the information terminal 50 accept the advance setting, the parent device 2 and the information terminal 50 transmit a setting signal to the child device 1. The subunit | mobile_unit 1 memorize | stores the setting content in the memory | storage part 16 of an own machine according to the received setting signal. Then, when an input of the room number from the operator H1 actually occurs, the slave unit 1 refers to the storage unit 16 and displays the call destination information A1 in a low display according to the setting content corresponding to the input room number. (Or non-display) is executed (or not executed). Even in this configuration, the confidentiality of the callee information A1 can be improved by an input from the parent device 2 or the information terminal 50.

  Note that the functions similar to those of the communication device (base unit 2 and information terminal 50) in the modified example 3 are the processing method of the communication device (base unit 2 and information terminal 50), a computer program, or a non-temporary recording of the computer program. It may be embodied by a recording medium or the like.

(3.4) Other Modifications In the basic example, even when there is no operation input related to switching to low display, the period during which low display is executed is only the second period T2 during a call, The first period T1 may be included, and the third period T3 may also be included.

  In the basic example, the slave unit 1 executes the low display in the second period T2 during a call even if there is no operation input related to switching to the low display. However, the subunit | mobile_unit 1 may be comprised so that the operator H1 can select the effective / invalidity of low display also in the 2nd period T2 during a telephone call.

  In the basic example, the slave unit 1 is configured to be able to accept an operation input related to switching to low display and the cancellation thereof. However, the configuration for receiving such an operation input is not an essential configuration in the slave unit 1. The subunit | mobile_unit 1 may be comprised so that switching to non-display or low display may be performed at a predetermined timing.

  In the basic example, the display unit 18 is a touch panel type liquid crystal display, but may not be a touch panel type. The subunit | mobile_unit side operation part 14 may be comprised only from the some push button P1. That is, switching to low display (or non-display) and cancellation of low display (or non-display) may be performed by a push operation on any push button P1.

  In the basic example, the input and determination of the room number is performed by pressing the plurality of push buttons P1. However, the plurality of push buttons P <b> 1 are not essential components for the child device 1. The subunit | mobile_unit side operation part 14 is comprised only from the display part 18, and the input and determination of a room number may also be performed by the touch operation to the display part 18. FIG.

  The non-display and various low-display functions in the basic example and the modified examples 1 and 2 may be appropriately changed according to the installation environment or the request of the slave unit 1. For example, even if the contractor or manager of the slave unit 1 can select either the non-display function or the low-display function through a touch operation on the display unit 18 of the slave unit side operation unit 14 Good. In addition, when a low display function is selected, it may be possible to select which one of a plurality of types of low display functions is adopted.

  The various low display functions described above may be applied in combination. When the callee information A1 is a four-digit number “1024”, a different low-display function may be assigned to each number. For example, “1” may be a mosaic display, “0” may be a small number size, “2” may be a light color, and “4” may be a distorted number display.

(4) Advantages As described above, the intercom entrance apparatus (slave unit 1) according to the first aspect includes the display unit (18). The display unit (18) displays the callee information (A1) accepted by the operation input. The call destination information (A1) is information for specifying the call destination (C1). The display unit (18) displays the call within at least one of the first period (T1) during which the call destination (C1) is calling and the second period (T2) during which a call is being made with the call destination (C1). The previous information (A1) can be hidden or displayed with low visibility. According to the first aspect, it is possible to improve confidentiality regarding the callee information (A1).

  Regarding the intercom entrance apparatus (slave device 1) according to the second aspect, in the first aspect, the display unit (18) displays the callee information (A1) in a non-displayed or low state in response to reception of a predetermined operation. It is preferable to switch to display. According to the 2nd aspect, it can switch to non-display or low display at arbitrary timings, and the convenience is improved.

  Regarding the intercom entrance apparatus (slave unit 1) according to the third aspect, in the first or second aspect, the display unit (18) is configured to respond to a signal received from the outside of the interphone entrance apparatus (slave unit 1). It is preferable to switch the call destination information (A1) to non-display or low display.
