DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an intercom device and a control system incorporating the intercom device according to the present invention will be described with reference to the drawings.

[0015] Fig. 1 is a configuration diagram showing an intercom device 1 according to the present invention. As shown in Fig. 1, the intercom device 1 is used, for example, in an apartment building or other collective housing M in which a plurality of dwelling units are partitioned within a single building. The intercom device 1 includes a collective entrance device 10 (10A to 10C: an example of an entrance device), a management room master device 20, a room master device 30, and a control device 40. The collective entrance device 10, the management room master device 20, the room master device 30, and the control device 40 are connected to each other via a network (in this example, a LAN: Local Area Network) through which communication is performed according to a general-purpose protocol.

[0016] The collective entrance unit 10A-10C (hereinafter collectively referred to as collective entrance unit 10) are installed at the building entrance or common space of the collective housing M. The collective entrance unit 10 is configured, for example, to be able to call the resident room master unit 30 and the management room master unit 20 in the collective housing M. The collective entrance unit 10 is also configured, for example, to be able to capture video of visitors.

[0017] Examples of collective entrance machines 10 include contact-type collective entrance machines equipped with a stationary operation reception unit (hardware device) as shown in collective entrance machines 10A and 10C, and non-contact-type collective entrance machines equipped with an aerial display type touch display as shown in collective entrance machine 10B. For example, the contact-type collective entrance machine 10A is equipped with an operation unit 11 for inputting room numbers, etc., a call unit 12 for talking with residents, etc., a camera 13 for photographing visitors, a display unit 14 for displaying various information, etc. The non-contact-type collective entrance machine 10B is equipped with a camera 120 for photographing visitors, an aerial touch display 100 for displaying an image in the air (hereinafter referred to as an aerial image), etc.

[0018] The collective entrance unit 10A-10C stores unique information (for example, collective entrance unit ID: identification) that identifies each collective entrance unit. The collective entrance unit 10 is connected to the control device 40 via an intercom line (dedicated line) L1. The collective entrance unit 10 can communicate with the room master unit 30 and the management room master unit 20 via the control device 40. In this example, three collective entrance units (collective entrance units 10A-10C) are connected to the control device 40, but the number of units that can be connected is not limited to this number.

[0019] The control room master unit 20 is installed in a control room of an apartment building. The control room master unit 20 includes an operation unit 21, a call unit 22, a display unit 23, etc. The control room master unit 20 stores unique information (e.g., a control room master unit ID, etc.) that identifies the control room master unit. The control room master unit 20 is connected to the control device 40 via an intercom line L2. The control room master unit 20 can communicate with the room master units 30, the collective entrance unit 10, etc. via the control device 40.

[0020] The room master unit 30 is installed in each residence of the apartment building. The room master unit 30 includes a display unit 31, an operation unit 32, and a call unit 33. The room master unit 30 stores unique information (e.g., a room master unit ID) that identifies each room master unit. The room master unit 30 is connected to the control device 40 via an intercom line L3. The room master unit 30 can communicate with the collective entrance unit 10, the management room master unit 20, and the like via the control device 40.

[0021] The control device 40 controls communications between the collective entrance unit 10, the management room master unit 20, and the room master unit 30, which are connected via an intercom line. The control device 40 stores unique information (e.g., a control device ID) that identifies the control device.

[0022] 2 is a schematic diagram of a collective entrance device 10B equipped with an aerial touch display 100. As shown in FIG. 2, the collective entrance device 10B includes an aerial touch display 100 capable of displaying an aerial image G toward a visitor W, and a control unit 110 that controls the operation of the aerial touch display 100.

[0023] The aerial touch display 100 includes a display device 101, an optical member 102, and a detection unit 103.

[0024] Display device 101 is a device that emits light P for generating aerial image G. Display device 101 is composed of, for example, a light source (such as an LED (Light Emitting Diode)), a lens unit, a liquid crystal display, etc. Display device 101 is communicatively connected to control unit 110. Aerial image G is formed in, for example, a rectangular shape (see FIG. 7).

[0025] The optical member 102 is a member that reflects and transmits the light P emitted from the display device 101, and forms an aerial image G in a predetermined space to be displayed toward the visitor W. The light emitted from the display device 101 is reflected by and transmitted through the optical member 102, and is collected at a position that is plane-symmetrical to the optical member 102. The collected light diverges again, and is observed by the visitor W as the aerial image G in the space above the aerial touch display 100.

[0026] The detection unit 103 detects an operation input by the visitor W with respect to the aerial image G. The detection unit 103 is configured with a three-dimensional distance sensor capable of measuring the distance to an object in space. The detection unit 103 is communicatively connected to the control unit 110.

[0027] The control unit 110 controls the display device 101 and the detection unit 103 of the aerial touch display 100. For example, the control unit 110 determines the spatial position and movement of the fingertip of the visitor W based on information acquired by the detection unit 103. The control unit 110 also changes the display content of the aerial image G generated by the light P emitted from the display device 101 in response to an operation input to the aerial image G from the visitor W. The control unit 110 also changes the display position, display angle, display mode, etc. of the aerial image G generated by the light P emitted from the display device 101 in response to the visitor W operating the aerial image G.

[0028] First embodiment 3 is a diagram showing the aerial touch display 100 of the collective entrance device 10B in the intercom device 1 of the first embodiment. As shown in FIG. 3, the collective entrance device 10B includes a camera 120 (an example of a sensor) for capturing an image of a visitor W in front of the aerial touch display 100. The camera 120 is disposed at a position where it is possible to capture a facial image of the visitor W. For example, the camera 120 is installed in the space above and behind the aerial touch display 100.

[0029] The intercom device 1 of the first embodiment operates, for example, as follows.

[0030] The camera 120 captures an image of the visitor W and detects the eye level of the visitor W from the captured facial image of the visitor W. The camera 120 transmits the detected eye level information of the visitor W to the control unit 110.

[0031] Based on the received eye-line information of visitor W, control unit 110 determines the display position of the aerial image G to be displayed to visitor W. Control unit 110 compares the eye-line height of visitor W with a predetermined threshold value, and determines the display position of the aerial image G based on the comparison result. When the eye-line height of visitor W is equal to or greater than the predetermined threshold value, control unit 110 sets the display position of the aerial image G higher than when the eye-line height is less than the predetermined threshold value.

[0032] For example, in the case of visitor W1, control unit 110 compares eye level H1 of visitor W1 with a predetermined threshold, and when eye level H1 is equal to or greater than the predetermined threshold, displays the display position of aerial image G1 to be displayed to visitor W1 at height h1. In the case of visitor W2, control unit 110 compares eye level H2 of visitor W2 with a predetermined threshold, and when eye level H2 is less than the predetermined threshold, displays the display position of aerial image G2 to be displayed to visitor W2 at height h2. The reference position for height is the position of optical member 102.

[0033] The control unit 110 sets the height h1 of the display position of the aerial image G1 displayed to a visitor W1 whose eye line height H1 is equal to or greater than a predetermined threshold value to be higher than the height h2 of the display position of the aerial image G2 displayed to a visitor W2 whose eye line height H2 is less than the predetermined threshold value.

[0034] Control unit 110 changes the display position at which aerial image G is displayed to a predetermined display position by changing the position and angle of display device 101 in housing 100a of aerial touch display 100. Specifically, control unit 110 changes the display position of aerial image G by changing the facing position and facing angle of display device 101 with respect to optical member 102. For example, when aerial image G2 is to be displayed at a position lower than aerial image G1, the position of display device 101 in housing 100a may be higher than the position of display device 101 when aerial image G1 is displayed. Thereby, when aerial image G2 is displayed, the angle of incidence of light P emitted from display device 101 with respect to optical member 102 is made acuter than the angle of incidence when aerial image G1 is displayed, so that aerial image G2 can be displayed at a position lower than aerial image G1.

[0035] As described above, the intercom device 1 of the first embodiment includes a collective entrance device 10B (an example of an entrance slave device) for a visitor W to call a resident and talk to him / her, and a room master device 30 for a resident to respond to the call from the collective entrance device 10B. The collective entrance device 10B includes an aerial touch display 100 for displaying an aerial image G toward the visitor W, and a control unit 110 for changing the display position of the aerial image G. The aerial touch display 100 includes a display device 101 that emits light for generating the aerial image G, an optical member 102 that reflects and transmits the light to form an image of the aerial image G in a predetermined space, and a detection unit 103 that detects an operation input of the visitor W on the aerial image G. According to this configuration, the display position of the aerial image G used as an operation reception unit of the collective entrance device 10B can be changed, so that the operability of the collective entrance device 10B equipped with the aerial touch display 100 is greatly improved.

[0036] Moreover, the intercom device 1 further includes a camera 120 that is arranged in a predetermined space and can detect the eye height H of the visitor W. The control unit 110 changes the display position of the aerial image G based on the eye height H of the visitor W detected by the camera 120. Specifically, when the eye height H of the visitor W is equal to or greater than a predetermined threshold, the control unit 110 raises the display position of the aerial image G higher than when the eye height H is lower than the predetermined threshold. In this way, by changing the display position of the aerial image G according to the eye height H of the visitor W, the operability of the collective entrance device 10B equipped with the aerial touch display 100 is not impaired even when the visitor W is, for example, a person shorter than normal (e.g., a child) or a person taller than normal (e.g., a foreigner). Therefore, good operability can be provided for any visitor W.

[0037] In the above first embodiment, the camera 120 is installed in the space above the rear of the aerial touch display 100, but the present invention is not limited to this. For example, the camera 120 may be installed in the housing of the aerial touch display 100. In addition, when a contact-type collective entrance machine 10A having a stationary hardware device is installed together with the aerial touch display 100, a camera common to the camera 13 installed in the collective entrance machine 10A may be used.

[0038] (Modification) FIG. 4 is a diagram showing a modified example of the air touch display 100 shown in FIG. The operation of the intercom device 1 equipped with the modified aerial touch display 100A is, for example, as follows.

[0039] Camera 120 captures an image of visitor W and detects the eye level of visitor W from the captured face image of visitor W. Camera 120 transmits the detected eye level information of visitor W to control unit 110A.

[0040] Based on the received line-of-sight information of visitor W, control unit 110A determines the display angle of the aerial image G to be displayed to visitor W. For example, control unit 110A compares the height of the line of sight of visitor W with a predetermined threshold value, and determines the display angle of the aerial image G based on the comparison result.

[0041] When the height of the line of sight of visitor W is higher than a predetermined threshold, control unit 110A sets the display angle of aerial image G3 so that, for example, the bottom side bs of rectangular aerial image G3 is tilted in a direction closer to visitor W than the top side ts. Also, when the height of the line of sight of visitor W is higher than a predetermined threshold, control unit 110A may set the display angle of aerial image G3 so that the image surface of aerial image G3 is approximately perpendicular to the front-to-rear direction of aerial touch display 100A. Note that the side of aerial touch display 100A that visitor W faces is defined as the front side of aerial touch display 100A.

[0042] For example, when visitor W's line of sight is high (in the case of a tall visitor), the display angle of aerial image G3 may be set so that the elevation angle of the image plane is large, as shown in aerial image G3, and when visitor W's line of sight is low (in the case of a short visitor), the display angle of aerial image G4 may be set so that the elevation angle of the image plane is smaller than that of aerial image G3, as shown in aerial image G4.

[0043] In addition, when the height of the visitor W's line of sight is below a predetermined threshold value, the control unit 110A may set the display angle of the aerial image G5 so that, for example, the upper side ts of the rectangular aerial image G5 is inclined in a direction closer to the visitor W than the lower side bs, as shown in Figure 4 for the aerial image G5.

[0044] Control unit 110A changes the position and angle of display device 101 in housing 100Aa of aerial touch display 100 to change the display angle at which aerial image G is displayed to a predetermined display angle. Specifically, control unit 110A changes the facing position and facing angle of display device 101 with respect to optical member 102 to change the display angle of aerial image G. For example, when aerial image G4 is displayed, the position of display device 101 in housing 100a may be made higher than the position of display device 101 when aerial image G3 is displayed, and the angle of display device 101 may be changed. Thereby, when aerial image G4 is displayed, the angle of incidence of light P emitted from display device 101 with respect to optical member 102 is made more acute than the angle of incidence when aerial image G3 is displayed, so that aerial image G4 can be displayed at a lower position than aerial image G3 and with an elevation angle of the image plane smaller than that of aerial image G3.

[0045] As described above, according to the intercom device 1 equipped with the modified aerial touch display 100A, the collective entrance device 10B includes the aerial touch display 100A for displaying the aerial image G toward the visitor W, and the control unit 110A for changing the display angle of the aerial image G. As a result, the display angle of the aerial image G used as the operation reception unit of the collective entrance device 10B can be changed, greatly improving the operability of the collective entrance device 10B equipped with the aerial touch display 100A.

[0046] Furthermore, according to intercom device 1 equipped with aerial touch display 100A of the modified example, the display angle of aerial image G can be changed according to eye height H of visitor W detected by camera 120. Specifically, when the eye height of visitor W is equal to or lower than a predetermined threshold, the display angle can be changed so that upper side ts of rectangular aerial image G is inclined in a direction closer to visitor W than lower side bs. Therefore, for example, even if visitor W is a person shorter than normal (such as a child), the operability of collective entrance device 10B is not impaired.

[0047] Furthermore, according to the intercom device 1 equipped with the modified aerial touch display 100A, when the height of the visitor W's line of sight is higher than a predetermined threshold value, the display angle is changed so that the aerial image G is vertical, or so that the lower side bs is tilted in a direction closer to the visitor W than the upper side ts. As a result, when a person of normal height or taller than normal operates the aerial touch display 100A, the aerial image G is displayed at the same angle as the operation unit of the conventional collective entrance device 10A as a stationary hardware device, so that the aerial touch display 100A can be operated without discomfort.

[0048] Second Embodiment Fig. 5 is a schematic diagram of a control system S11 that controls the intercom device 1 of the second embodiment. The control system S11 is used in an intercom system equipped with the intercom device 1. As shown in Fig. 5, the control system S11 includes a collective entrance unit 10A (an example of hardware equipment), a collective entrance unit 10B, a camera 120, a room master unit 30 (see Fig. 1), and a control device 40 (see Fig. 1).

[0049] As described in Fig. 1, the collective entrance machine 10A has an operation unit 11 as an operation receiving unit. When the display unit 14 of the collective entrance machine 10A is configured as a touch display, the display unit 14 functions as the operation receiving unit. The collective entrance machine 10A also has a control unit 15 that controls the operation of the collective entrance machine 10A.

[0050] As described in Fig. 2, the collective entrance machine 10B has an aerial touch display 100 and a control unit 110. The aerial touch display 100 has a display device 101, an optical member 102, and a detection unit 103, and displays an aerial image G toward a visitor W (an example of a user). The control unit 110 controls the operation of the aerial touch display 100. In addition, the control unit 110 is connected to be able to communicate with the control unit 15 of the collective entrance machine 10A via an intercom line L1.

[0051] The camera 120 is a camera that can detect a visitor W and capture an image of the detected visitor W. In this embodiment, since the collective entrance machine 10A and the collective entrance machine 10B are installed side by side, a single camera 120 is provided as a camera shared by both collective entrance machines. The camera 120 is connected to the collective entrance machine 10A and the collective entrance machine 10B so as to be able to communicate with each other. In addition, when the collective entrance machine 10A and the collective entrance machine 10B are installed side by side, for example, the camera 13 provided in the collective entrance machine 10A may be used as a camera shared by both collective entrance machines.

[0052] The room master unit 30 (an example of a calling device) is a device that can be called based on a calling operation from the collective entrance unit 10A or the collective entrance unit 10B, as described with reference to FIG.

[0053] 1, the control device 40 is connected to the collective entrance device 10 and the room master device 30, and controls communication between the collective entrance device 10 and the room master device 30. When a call operation is input to the collective entrance device 10A and the collective entrance device 10B, the control device 40 executes a call process to call the room master device 30 based on a call signal received from the control unit 15 of the collective entrance device 10A and the control unit 110 of the collective entrance device 10B.

[0054] An example of the operation of the control system S11 having such a configuration will be described with reference to FIG. First, the control system S11 detects a visitor W by the camera 120 (step S1). The camera 120 starts capturing an image of the detected visitor W (step S2). The camera 120 also transmits a detection signal notifying the fact that the visitor W has been detected to the collective entrance device 10A and the collective entrance device 10B.

[0055] Next, based on the received detection signal, control unit 15 of collective entrance unit 10A transitions from a standby state to an operating state, displays a predetermined image on display unit 14, and sets operation unit 11 to an operable reception state (step S3). Based on the received detection signal, control unit 110 of collective entrance unit 10B transitions from a standby state to an operating state and starts displaying aerial image G (step S4). As a result, collective entrance unit 10A and collective entrance unit 10B transition to an input waiting state in which they wait for operation input from visitor W.

[0056] Next, for example, suppose that a first operation input from visitor W is made to the operation unit 11 of collective entrance machine 10A, and furthermore, a second operation input from visitor W is made to the aerial image G of collective entrance machine 10B. In this case, the control unit 15 of collective entrance machine 10A accepts the first operation input (step S5). The control unit 110 of collective entrance machine 10B accepts the second operation input (step S6). The control units 15 and 110 transmit and receive the accepted reception information to each other, and determine which of the first and second operation inputs was accepted later. Specifically, the control units 15 and 110 determine whether the first operation input was accepted later than the second operation input (step S7).

[0057] If it is determined that the first operation input was received after the second operation input (Yes in step S7), the control units 15 and 110 cancel the process based on the second operation input received first, and execute the process based on the first operation input received later (step S8).On the other hand, if it is determined that the first operation input was not received after the second operation input (No in step S7), the control units 15 and 110 cancel the process based on the first operation input received first, and execute the process based on the second operation input received later (step S9).

[0058] For example, suppose that visitor W first performs a second operation input on the aerial image G of collective entrance unit 10B, but becomes confused about the operation method midway through the operation, so stops the second operation input and performs a first operation input on operation unit 11 of collective entrance unit 10A. In this case, control unit 15 and control unit 110 cancel the process based on the first second operation input to collective entrance unit 10B, and execute the process based on the later first operation input to collective entrance unit 10A.

[0059] For example, suppose visitor W first starts a first operation input to operation unit 11 of collective entrance unit 10A, but stops touching operation to operation unit 11 midway through the operation and performs a second operation input to aerial image G of collective entrance unit 10B. In this case, control unit 15 and control unit 110 cancel the process based on the first operation input to collective entrance unit 10A that was performed first, and execute the process based on the second operation input to collective entrance unit 10B that was performed later.

[0060] Moreover, the control system S11 may operate, for example, as follows. First, similarly to the above operation example, collective entrance device 10A displays a predetermined image on display unit 14 and sets operation unit 11 to an operable reception state based on the detection signal received from camera 120. Collective entrance device 10B starts displaying aerial image G based on the detection signal received from camera 120.

[0061] Next, for example, suppose that one of the first operation input of visitor W to the operation unit 11 of collective front door unit 10A and the second operation input of visitor W to the aerial image G of collective front door unit 10B is accepted, and a call process of the room master unit 30 corresponding to the operation input is started. Then, suppose that the other of the first operation input of visitor W to the operation unit 11 of collective front door unit 10A and the second operation input of visitor W to the aerial image G of collective front door unit 10B is accepted after the call process is started. In this case, the control unit 15 of collective front door unit 10A and the control unit 110 of collective front door unit 10B send and receive reception information of the operation inputs they have accepted, and determine which of the first and second operation inputs was accepted first, and confirm that the call process of the room master unit 30 corresponding to the first operation input has been started. Based on the discrimination results and confirmation results, the control unit 15 and the control unit 110 stop accepting the other operation input (subsequent operation input) and execute processing (processing after the call processing) based on one operation input (initial operation input).

[0062] For example, visitor W first performs a second operation input on the aerial image G of collective entrance unit 10B, and a call process of the room master unit 30 corresponding to the second operation input is started. However, after the call process is started, visitor W becomes worried that the operation may have been incorrect, and starts a first operation input on the operation unit 11 of collective entrance unit 10A. In this case, control unit 15 and control unit 110 do not accept the first operation input started later on to collective entrance unit 10A, and continue to execute the call process based on the first second operation input to collective entrance unit 10B.

[0063] This process is also the same when the order of the second operation input to the aerial image G of the collective entrance unit 10B and the first operation input to the operation unit 11 of the collective entrance unit 10A is reversed; once the call process based on the operation input made first to the collective entrance unit is started, no subsequent operation inputs to the collective entrance unit are accepted.

[0064] As described above, the control system S11 for controlling the intercom device 1 of the second embodiment includes a collective entrance device 10A (hardware device) having an operation unit 11, an aerial touch display 100 (collective entrance device 10B) having a display device 101, an optical member 102, and a detection unit 103 for displaying an aerial image G, and a control unit 15 for controlling the collective entrance device 10A and a control unit 110 for controlling the aerial touch display 100. When the control units 15 and 110 receive both a first operation input by a visitor W to the operation unit 11 and a second operation input by a visitor W to the aerial image G, the control units 15 and 110 cancel the process based on the first operation input of the first operation input and the second operation input that were received first, and execute the process based on the second operation input that was received later. According to this configuration, even if there is a mixture of operation input to the contact-type collective entrance unit 10A, which is a hardware device, and operation input to the non-contact-type collective entrance unit 10B, which touches an aerial image, the later operation input is given priority, thereby making it possible to improve the control quality of the intercom device 1, in which both hardware devices and aerial images coexist.

[0065] Moreover, the control system S11 that controls the intercom device 1 of the second embodiment further includes a camera 120 that detects a visitor W. Then, when the visitor W is detected by the camera 120, the control unit 110 starts displaying the aerial image G. According to this configuration, the aerial image G is displayed only when a visitor W is present, so that the load on the control system S11 can be reduced and the power consumption of the aerial touch display 100 can be reduced.

[0066] In addition, the control system S11 that controls the intercom device 1 of the second embodiment further includes a room master unit 30 that can be called by accepting a first operation input to the operation unit 11 of the collective entrance unit 10A or a second operation input to the aerial image G of the collective entrance unit 10B. Then, when the control unit 15, 110 starts the call processing of the room master unit 30 by accepting one of the first operation input and the second operation input, and then accepts the other of the first operation input and the second operation input, it executes processing based on one operation input without accepting the other operation input. If the other operation input is made after the call processing of the room master unit 30 is started by one operation input, and the other operation input is given priority, there is a risk that the called party will be confused and appropriate control will not be possible. In contrast, according to the above configuration, after the call processing by one operation input is started, the other operation input is canceled without being accepted, and the processing based on one operation input is continued, so that the called party is not confused and control quality can be maintained.

[0067] In the second embodiment, the control system S11 is used in an intercom system, but the present invention is not limited to this. For example, the control system S11 may be used in a nurse call system. In this case, a conventional nurse call master unit installed in a nurse station corresponds to a contact-type hardware device. An aerial touch display that displays the aerial image G to medical staff is installed next to the conventional nurse call master unit in the nurse station. A nurse call slave unit that allows a patient to call a nurse or that receives a call from the nurse call master unit corresponds to a calling device.

[0068] Third embodiment Next, an intercom system S12 equipped with the intercom device 1 of the third embodiment will be described with reference to Fig. 5 again. As shown in Fig. 5, the intercom device 1 in the intercom system S12 includes a contact-type collective entrance device 10A equipped with stationary hardware, a non-contact-type collective entrance device 10B that touches an aerial image G, a camera 120, and a room master device 30 (see Fig. 1).

[0069] The collective entrance unit 10A has an operation unit 11, a display unit 14, and a control unit 15, similar to the configuration described in the second embodiment.

[0070] The collective entrance device 10B has a first sensor 210 and a second sensor 220 in addition to the aerial touch display 100 and the control unit 110, which are configured as described in the second embodiment above. The first sensor 210 and the second sensor 220 are communicatively connected to the control unit 110. The aerial touch display 100 includes a display device 101, an optical member 102, and a detection unit 103, and displays an aerial image G toward a visitor W. The control unit 110 controls the operation of the aerial touch display 100.

[0071] The first sensor 210 detects the opening and closing of a first entrance K1 of the apartment building M. The first sensor 210 detects that a visitor W has passed through the first entrance K1 by detecting the opening and closing of the first entrance K1. The second sensor 220 detects the opening and closing of a second entrance K2 of the apartment building M. The second sensor 220 detects that a visitor W has passed through the second entrance K2 by detecting the opening and closing of the second entrance K2. The first entrance K1 and the second entrance K2 are automatic doors that open and close by detecting the presence or absence of a visitor W.

[0072] The collective entrance unit 10A and the collective entrance unit 10B are installed at a building entrance E2 provided between a first entrance K1 and a second entrance K2 of the apartment house M. The first sensor 210 is disposed near the first entrance K1 disposed between the building entrance E2 and the outside E1. The second sensor 220 is disposed near the second entrance K2 disposed between the building entrance E2 and the living area E3.

[0073] As described in the second embodiment above, the camera 120 detects the visitor W and captures an image of the detected visitor W. As described in the second embodiment above, the room master unit 30 is a device that can be called based on a call operation from the collective entrance unit 10A or the collective entrance unit 10B.

[0074] The intercom device 1 in the intercom system S12 operates, for example, as follows. When a visitor W visiting the apartment complex M passes through the first entrance K1, the first sensor 210 detects the opening and closing operation of the first entrance K1, and transmits a detection signal to the control unit 110 indicating the detection.

[0075] Control unit 110 starts displaying aerial image G toward visitor W based on the detection signal received from first sensor 210.

[0076] Next, the second entrance K2 is opened when the visitor W performs, for example, a predetermined operation input on the displayed aerial image G. Then, when the visitor W passes through the second entrance K2, the second sensor 220 detects the opening and closing operation of the second entrance K2, and transmits a detection signal indicating the detection to the control unit 110.

[0077] Control unit 110 stops the display of aerial image G based on the detection signal received from second sensor 220.

[0078] As described above, the intercom device 1 of the third embodiment includes a collective entrance device 10B for a visitor W to call a resident and a room master device 30 for a resident to respond to the call from the collective entrance device 10B. The collective entrance device 10B includes an aerial touch display 100 for displaying an aerial image G to a visitor W, the aerial touch display 100 having a display device 101 for emitting light for generating the aerial image G, an optical member 102 for reflecting and transmitting the light to form the aerial image G in a predetermined space, and a detection unit 103 for detecting an operation input of the visitor W on the aerial image G, a control unit 110 for controlling the aerial touch display 100, and a first sensor 210 for detecting the visitor W. Then, when the visitor W is detected by the first sensor 210, the control unit 110 starts displaying the aerial image G. According to this configuration, the operability can be improved by using the aerial touch display 100 as the collective entrance device 10B. Furthermore, since the aerial image G is displayed only when a visitor W is present, the power consumption of the aerial touch display 100 can be reduced.

[0079] Furthermore, according to intercom device 1 of the third embodiment, first sensor 210 is placed near first entrance K1 installed between building entrance E2 where collective entrance device 10B is installed and outside E1, and control unit 110 starts displaying aerial image G based on detection of opening or closing of first entrance K1 by first sensor 210. Therefore, the timing of starting display of aerial image G in response to the arrival of visitor W can be controlled with a simple configuration.

[0080] Moreover, the intercom device 1 of the third embodiment further includes a second sensor 220 disposed near a second entrance K2 installed between the building entrance E2 and the living area E3. Then, the control unit 110 stops the display of the aerial image G based on the detection of opening / closing of the second entrance K2 by the second sensor 220. According to this configuration, the display of the aerial image G is stopped based on the visitor W finishing the operation on the aerial image G of the aerial touch display 100, so that the effect of reducing the power consumption of the aerial touch display 100 can be further enhanced.

[0081] (Fourth embodiment) An example of an aerial image displayed on the aerial touch display 100 of the collective entrance device 10B in the intercom device 1 of the fourth embodiment will be described with reference to Figs.

[0082] The collective entrance machine 10B includes a camera 120 for capturing an image of a visitor W in front of the aerial touch display 100. The camera 120 is a camera capable of detecting the attributes of the visitor W based on the captured face image of the visitor W. The attributes of the visitor W include, for example, the height and age of the visitor W, or whether the visitor W is a person associated with the apartment complex M. The fact that the visitor W is a person associated with the apartment complex M is determined by capturing a face image in advance and registering it in the collective entrance machine 10B. The associated person may include, for example, a resident of the apartment complex M, the resident's relatives, friends, etc. The camera 120 is installed, for example, in the space above the rear of the aerial touch display 100, as described in the first embodiment.

[0083] Fig. 7 shows a first display mode of an aerial image G displayed by the aerial touch display 100. As shown in Fig. 7, the aerial image G in the first display mode is provided with a visitor image display section C1 and a call operation reception section C2. A facial image of a visitor W captured by the camera 120 is displayed on the visitor image display section C1. On the call operation reception section C2, a numeric keypad 41 for inputting the room number to be called, a call button 42 to be pressed after inputting the room number, a cancel button 43 with which the input number can be cancelled, etc. are displayed.

[0084] FIG. 8 shows a second display mode of the aerial image G displayed by the aerial touch display 100. As shown in FIG. 8, the entire area of ​​the aerial image G in the second display mode is composed of the call operation receiving section D. The call operation receiving section D is provided with an operation message section D1 in which the operation content of the aerial image G is displayed, a first operation section D2 in which a numeric keypad 51 for inputting the room number to be called is displayed, and a second operation section D3 in which a call button 52 to be pressed after inputting the room number is displayed. The second display mode is a mode with a simpler display mode than the first display mode shown in the call operation receiving section C2 of FIG. 7. The second display mode is, for example, a mode in which the number of operation buttons included in the call operation receiving section D is smaller than that in the first display mode, and the size of the operation buttons is larger. In addition, the second display mode is a mode in which the display characters are composed of only hiragana.

[0085] FIG. 9 shows a third display mode of the aerial image G displayed by the aerial touch display 100. As shown in FIG. 9, the aerial image G in the third display mode is provided with a visitor image display section F1 and a call operation reception section F2. The visitor image display section F1 displays a face image of the visitor W captured by the camera 120. The call operation reception section F2 displays an operation message 61 indicating the operation content of the aerial image G, a room number 62 indicating the visit destination in the apartment building M selected on the aerial touch display 100 side, a call button 63 for calling the selected room number, and the like. The third display mode is a mode that is displayed when the visitor W is determined to be a person associated with the apartment building M. In the third display mode, in order to improve the operability of the call input of the associated visitor W, for example, the input operation process of the room number is omitted.

[0086] The air touch display 100 in the intercom device 1 of the fourth embodiment operates, for example, as follows. The camera 120 captures an image of the visitor W and detects the height and age of the visitor W from the captured facial image of the visitor W. The camera 120 transmits the detected attribute information of the visitor W, such as the height and age, to the control unit 110.

[0087] Control unit 110 determines whether or not the height or age of visitor W is equal to or greater than a predetermined threshold value, based on the attribute information of visitor W received from camera 120. When control unit 110 determines that the height or age of visitor W is equal to or greater than a predetermined threshold value, it displays a first display mode in which numeric keypad 41, call button 42, cancel button 43, etc. are displayed in call operation receiving section C2 of aerial image G, as shown in Fig. 7.

[0088] On the other hand, when control unit 110 determines that visitor W's height or age is lower than a predetermined threshold, it displays a second display mode in which an operation message section D1, a first operation section D2, and a second operation section D3 are provided in call operation reception section D of aerial image G, as shown in Fig. 8. Control unit 110 displays the operation content in hiragana in operation message section D1, for example, "Please enter the room number and then press 'Call'". Then, first operation section D2 and second operation section D3 display the minimum number of buttons that can execute the operation content.

[0089] Furthermore, the aerial touch display 100 in the intercom device 1 of the fourth embodiment may operate, for example, as follows. Camera 120 captures an image of visitor W and detects from the captured facial image of visitor W whether visitor W is a person associated with apartment complex M. Camera 120 transmits the detected attribute information to control unit 110.

[0090] When the control unit 110 recognizes the visitor W as a person associated with the apartment complex M based on the attribute information of the visitor W received from the camera 120, it displays a third display mode in which an operation message 61, a room number 62, a call button 63, and the like are displayed in the call operation reception section F2 of the aerial image G as shown in FIG. 9. When the control unit 110 detects that the visitor W is an associated visitor W, it displays a room number associated with the visitor W, for example, "103", without the visitor W inputting an operation, and displays, for example, "If the displayed room number is correct, please press "Call" (call button 63)" as the operation message 61. In this case, when the call button 63 is pressed, for example, the door of the apartment complex entrance may be unlocked when the visitor W is a resident of the apartment complex M, and a call process to the room number "103" may be started when the visitor W is a friend.

[0091] On the other hand, if the control unit 110 recognizes that the visitor W is not a person associated with the apartment building M, it displays a first display mode in which a numeric keypad 41, a call button 42, a cancel button 43, etc. are displayed in the call operation reception section C2 of the aerial image G, as shown in Figure 7.

[0092] Also, for example, if the control unit 110 determines that the height or age of visitor W is lower than a predetermined threshold value and further that visitor W is a person associated with the apartment building M, it may display the room number associated with the visitor W in the first operation unit D2 of the call operation reception unit D in the aerial image G shown in Figure 8 without the visitor W having to enter any input operation, and may display "Please press 'Call'" in hiragana in the operation message unit D1.

[0093] As described above, the intercom device 1 of the fourth embodiment includes a collective entrance device 10B for a visitor W to call a resident and a room master device 30 for a resident to respond to a call from the collective entrance device 10B. The collective entrance device 10B includes an aerial touch display 100 for displaying an aerial image G to a visitor W, the aerial touch display 100 having a display device 101 for emitting light for generating the aerial image G, an optical member 102 for reflecting and transmitting the light to form an image of the aerial image G in a predetermined space, and a detection unit 103 for detecting an operation input of the visitor W on the aerial image G, and a control unit 110 for controlling the aerial touch display 100. The control unit 110 changes the display mode of the call operation reception unit C2 included in the aerial image G. According to this configuration, the display mode of the call operation reception unit C2 displayed on the aerial image G can be changed in the aerial touch display 100 used as the collective entrance device 10B, so that the operability of the collective entrance device 10B is greatly improved.

[0094] Moreover, the intercom device 1 of the fourth embodiment further includes a camera 120 that is arranged in a predetermined space and is capable of detecting attributes of a visitor W. Then, the control unit 110 changes the display mode of the call operation reception unit C2 based on the attributes detected by the camera 120. With this configuration, by changing the display mode of the call operation reception unit C2 in the aerial image G according to the attributes of the visitor W, such as the height or age of the visitor W, a novel collective entrance device 10B with excellent operability for various visitors W can be provided.

[0095] According to the intercom device 1 of the fourth embodiment, the attribute is at least one of the height and age of the visitor W. When the height or age is equal to or greater than a predetermined threshold, the control unit 110 displays the call operation reception unit C2 in the first display mode, and when the height or age is lower than the predetermined threshold, the control unit 110 displays the call operation reception unit D in the second display mode, which is a display mode simpler than the first display mode. For this reason, for example, when the visitor W is a child, the call operation reception unit D is displayed in the second display mode, which is a simple display mode, thereby providing an aerial touch display 100 that is easy for children to operate.

[0096] According to the intercom device 1 of the fourth embodiment, the second display mode includes at least one of a mode in which the number of operation buttons included in the call operation receiving unit D is reduced and a mode in which the size of the operation buttons is increased, compared to the first display mode. Therefore, even children can easily operate the aerial touch display 100.

[0097] Furthermore, according to the intercom device 1 of the fourth embodiment, the attributes include whether or not the visitor W is a person associated with the apartment building M in which the collective entrance device 10B is installed. If the visitor W is a person associated with the apartment building M, the control unit 110 displays the call operation reception unit F2 in a third display mode different from the first display mode, and if the visitor W is not a person associated with the apartment building M, the control unit 110 displays the call operation reception unit C2 in the first display mode. In this way, by adopting different display modes depending on whether the visitor W is, for example, a resident or not, it is possible to ensure security while improving operability.

[0098] Furthermore, according to the intercom device 1 of the fourth embodiment, the first display mode is a display mode including at least the numeric keypad 41, and the third display mode is a display mode including at least a display of a room number 62 in an apartment building M to which the visitor W is associated. Therefore, when the visitor W is a resident, a relative, a friend, or the like, a call button that allows the visitor W to directly call the associated room number 62 can be displayed in the aerial image G, thereby greatly improving operability.

[0099] Furthermore, for example, when the control unit 110 determines that the visitor W is a foreigner based on the attribute information received from the camera 120, the control unit 110 may change the language notation of the call operation reception units C2, D, and F2 to a predetermined foreign language. According to this configuration, for example, when there is a high possibility that the visitor is a foreigner, the call operation reception units C2, D, and F2 are displayed in English instead of Japanese, thereby improving the operability of the aerial touch display 100.

[0100] The present invention is not limited to the above-described embodiment, and can be freely modified, improved, etc. as appropriate. The material, shape, size, numerical value, form, number, location, etc. of each component in the above-described embodiment are arbitrary and not limited as long as the present invention can be achieved.
