Description

[Technical field]

[0001] The present invention relates to a technique for inputting lighting setting information. [Background technology]

[0002] Lighting has been used in various places for a long time. In general homes, the amount of light and color tone of lighting are rarely set precisely, but in art galleries and museums, the illuminance and color tone of lighting are often set precisely. However, the operation for setting the illuminance and color tone of lighting is not easy, and it has been a big burden for the person setting it. One example of a technology for reducing such a burden is disclosed in Patent Document 1. The technology disclosed in Patent Document 1 aims to provide a lighting control device that allows a user to easily change the dimming level and color adjustment level, and provides multiple operating modes, namely a dimming mode and a color adjustment mode, making it possible to perform dimming and color adjustment with a single lighting control device.

[0004] However, for example, in art galleries and museums, a large number of lights are installed due to their size. Therefore, even if the technology disclosed in Patent Document 1 is used, it is a huge burden to set the light intensity and color tone for each light individually. Furthermore, in art galleries and museums, the exhibits change for each exhibition that is held several times a year. Each time, it is necessary to reset the setting information such as the light intensity and color tone of each light to an optimal setting, which is a heavy burden for the workers. Such problems are not limited to art galleries and museums, but are common to facilities that use multiple lighting. In view of the above circumstances, the present invention aims to provide a technology that makes it possible to reduce the effort required to set up lighting in facilities that use multiple lighting. [Means for solving the problem]

[0012] Hereinafter, specific configuration examples of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram showing a system configuration of a dimming control system 100 of the present invention. The dimming control system 100 includes a plurality of lighting fixtures 10, a dimming control device 20, and a setting information input device 30. The dimming control system 100 is a system for setting and controlling the light intensity and color tone of a plurality of lighting fixtures 10. In the following description, an illuminance value is used as one piece of information indicating the light intensity of the lighting fixtures 10. However, other values ​​may be used as the information indicating the light intensity. For example, the information indicating the light intensity may be information indicating the ratio of the maximum output of the lighting, or information indicating the step of the dimming value. The plurality of lighting fixtures 10, the dimming control device 20, and the setting information input device 30 are communicatively connected via a network 90. ​​The network 90 may be a network using wireless communication or a network using wired communication. The network 90 may be configured by combining a plurality of networks. The network through which the lighting fixtures 10 and the dimming control device 20 communicate with each other may be configured by using different networks.

[0013] Lighting fixture 10 is a lighting device capable of changing illuminance and color tone between multiple levels. The power to lighting fixture 10 is turned on and off in response to a control signal transmitted from dimming control device 20. Lighting fixture 10 changes its illuminance and color tone in response to the control signal transmitted from dimming control device 20. Each lighting fixture 10 may be fixedly installed at a predetermined position.

[0014] The dimming control device 20 controls the operation of each lighting fixture 10 included in the dimming control system 100. For example, the dimming control device 20 controls the illuminance and color tone of each lighting fixture 10. The dimming control device 20 may control each lighting fixture 10 using, for example, a unique communication protocol, or may control each lighting fixture 10 using a specific existing communication protocol. Specific examples of existing communication protocols include DALI (registered trademark), DMX512, DALI2, etc.

[0015] The dimming control device 20 is configured using information devices such as a personal computer or a dedicated device. Fig. 2 is a diagram showing a specific example of a functional configuration of the dimming control device 20. The dimming control device 20 includes a communication unit 21, a storage unit 22, and a control unit 23. Each functional unit of the dimming control device 20 will be described below.

[0016] The communication unit 21 is a communication device that communicates with other devices. The communication unit 21 communicates with other devices (for example, the lighting fixture 10 and the setting information input device 30) via a network 90, for example.

[0017] The storage unit 22 is configured using a storage device such as a magnetic hard disk device, a semiconductor storage device, etc. The storage unit 22 functions as a map information storage unit 221, a template information storage unit 222, a group information storage unit 223, and a setting information storage unit 224, for example.

[0018] The map information storage unit 221 stores information (hereinafter referred to as "map information") related to a map of a facility in which lighting fixtures 10 are installed (hereinafter referred to as "target facility"). The map information stores, for example, a map of an area in which at least lighting fixtures 10 are installed in the target facility, information indicating the locations where each lighting fixture 10 is installed, and destination information (e.g., device identification information, address information, etc.) used when transmitting control information to each lighting fixture 10. By referring to the map information stored by the map information storage unit 221, the computer can display on the map where each lighting fixture 10 is installed in the target facility. In addition, by referring to the map information stored by the map information storage unit 221, the computer can obtain destination information for transmitting a control signal to each lighting fixture 10 specified on the map by the user.

[0019] The template information storage unit 222 stores template information. The template information has information on the illuminance of each lighting fixture 10 for each predetermined unit (hereinafter referred to as a "lighting set") that includes multiple lighting fixtures. The illuminance information of each lighting fixture 10 defined in the template information may be, for example, a relative value of the illuminance of each lighting fixture 10 (hereinafter referred to as "relative illuminance") or an absolute value of the illuminance of each lighting fixture 10. The template information may further include information on color tone (for example, color temperature).

[0020] FIG. 3 is a diagram showing a specific example of a lighting set. One lighting set includes multiple lighting fixtures 10, and the installation position of each lighting fixture 10 is determined. For example, the lighting set of FIG. 3 includes four lighting fixtures 10 (10_1 to 10_4) provided to illuminate an exhibition space 50. In the lighting set, the relative value (ratio) of illuminance between each lighting fixture 10 at each position and other lighting fixtures included in the same lighting set is determined as the relative illuminance. For example, the relative illuminance may be determined as follows in the lighting set shown in FIG. 3. Lighting fixture 10_1:5 Lighting fixture 10_2:20 Lighting fixture 10_3:10 Lighting fixture 10_4:2

[0021] When the relative illuminance of a lighting set is determined in this manner, the ratio of the illuminance of the four lighting fixtures 10 is changed while maintaining the above-mentioned relative illuminance relationship. For example, when an operation to increase the illuminance of this lighting set is performed, the settings are updated so that the illuminance value of each lighting fixture 10 is increased while maintaining the above-mentioned relative illuminance relationship. For example, when the four lighting fixtures 10 used in the lighting set of FIG. 3 have the same maximum illuminance value, Lighting fixture 10_1: 10% of maximum illuminance Lighting fixture 10_2: 40% of maximum illumination Lighting fixture 10_3: 20% of maximum illumination Lighting fixture 10_4: 4% of maximum illumination

[0022] The illuminance of each lighting device may be set as follows. If an operation to lower the illuminance of this lighting set is subsequently performed, Lighting fixture 10_1: 5% of maximum illumination Lighting fixture 10_2: 20% of maximum illumination Lighting fixture 10_3: 10% of maximum illumination Lighting fixture 10_4: 2% of maximum illumination

[0023] The illuminance of each lighting device may be set as follows. Note that, although the illuminance of each lighting device 10 is shown here as a percentage of the maximum illuminance, it may be expressed in other ways. For example, it may be expressed as a number of steps separated by a predetermined width from the minimum illuminance to the maximum illuminance, or it may be expressed as an absolute value of illuminance.

[0024] The lighting set shown in FIG. 3 is only one specific example, and lighting sets of other modes may be defined. Furthermore, multiple types of lighting sets may be defined in one target facility. The template information may further include label information in addition to the relative illuminance for each lighting set. The label information is information indicating the situation in which the template is used. For example, information indicating the type of exhibit for which the template is used may be given as the label information. As specific examples of the type of exhibit, values ​​such as hanging scroll, folding screen, and kimono may be given. Information indicating the center of gravity of light may be defined as the label information. For example, label information such as the entire wall surface and the center of the eyeline (gaze line) may be defined.

[0025] The group information storage unit 223 stores group information. The group information is information about a group including one or more lighting devices 10. The group information may be defined, for example, in units of one or more lighting sets. The group information includes information about the lighting devices 10 included in the group. The group information may be defined, for example, by a user, or may be determined in advance. The group information may be deleted or updated, for example, by a user.

[0026] The setting information storage unit 224 stores setting information. The setting information includes setting values ​​such as illuminance and color tone for each lighting device 10.

[0027] The control unit 23 is configured using a processor such as a CPU (Central Processing Unit) and a memory. The control unit 23 functions as a recording control unit 231, a setting support unit 232, and a lighting control unit 233 by the processor executing a program. All or part of the functions of the control unit 23 may be realized using hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). The above program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a semiconductor storage device (for example, an SSD: Solid State Drive), or a storage device such as a hard disk or a semiconductor storage device built into a computer system. The above program may be transmitted via an electric communication line.

[0028] The recording control unit 231 acquires predefined map information and template information from another device (e.g., the setting information input device 30 or another device) and records it in the storage unit 22. For example, when the dimming control system 100 is introduced into the target facility, the recording control unit 231 may receive map information registered in the initial settings from another device and record it in the map information storage unit 221.

[0029] The setting support unit 232 supports the user in setting the illuminance and color tone of each lighting fixture 10. For example, the setting support unit 232 provides information required for setting to the setting information input device 30 used by the user. For example, the setting support unit 232 may provide template information or group information to the setting information input device 30. For example, the setting support unit 232 receives information set based on the template information or group information (information on settings given per lighting set, information on settings given per group) from the setting information input device 30, calculates setting values ​​for each lighting fixture 10 included in each lighting set or each group based on the received information, and records the calculated values ​​in the setting information storage unit 224. Note that the calculation of the setting values ​​for each lighting fixture 10 included in each lighting set or each group may be performed in the setting information input device 30. In this case, the setting support unit 232 receives setting values ​​for each lighting fixture 10 from the setting information input device 30 and records the received values ​​in the setting information storage unit 224.

[0030] The setting support unit 232 may transmit data of a graphical user interface for changing illuminance on a lighting set basis or a group basis to the setting information input device 30. In this case, the setting support unit 232 may receive information indicating a change in setting caused by a user operation on the graphical user interface (information on settings given on a lighting set basis, information on settings given on a group basis) from the setting information input device 30. The setting support unit 232 calculates setting values ​​for each lighting device 10 included in each lighting set or each group based on the received information, and records the calculated values ​​in the setting information storage unit 224. Note that the setting values ​​for each lighting device 10 included in each lighting set or each group may be calculated in the setting information input device 30. In this case, the setting support unit 232 receives setting values ​​for each lighting device 10 from the setting information input device 30, and records the received values ​​in the setting information storage unit 224.

[0031] The lighting control unit 233 controls the illuminance and color tone of each lighting fixture 10 based on the setting information stored in the setting information storage unit 224. When information indicating whether to power a lighting fixture 10 on or off is input from the setting information input device 30 or a switch device (not shown), the lighting control unit 233 controls the power on or off of each lighting fixture 10 based on the input information.

[0032] 4 is a diagram showing a specific example of the functional configuration of the setting information input device 30. The setting information input device 30 is configured using information devices such as a smartphone, a tablet, a personal computer, a dedicated device, etc. The setting information input device 30 includes a communication unit 31, an operation unit 32, a display unit 33, a storage unit 34, and a control unit 35.

[0033] The communication unit 31 is a communication device. The communication unit 31 may be configured as, for example, a network interface. The communication unit 31 performs data communication with other devices via the network 90 in response to the control of the control unit 35. The communication unit 31 may be a device that performs wireless communication or a device that performs wired communication.

[0034] The operation unit 32 is configured using existing input devices such as a keyboard, a pointing device (mouse, tablet, etc.), buttons, a touch panel, etc. The operation unit 32 is operated by a user when inputting a user's instruction to the setting information input device 30. The operation unit 32 may be an interface for connecting an input device to the setting information input device 30. In this case, the operation unit 32 inputs an input signal generated in the input device in response to a user's input to the setting information input device 30. The operation unit 32 may be configured using a microphone and a voice recognition device. In this case, the operation unit 32 performs voice recognition on a word spoken by the user, and inputs character string information of the recognition result to the setting information input device 30. The operation unit 32 may be configured in any way as long as it is configured to input a user's instruction to the setting information input device 30.

[0035] Display unit 33 is an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display. Display unit 33 displays a graphical user interface for setting the illuminance and color tone of lighting device 10. Data for the displayed graphical user interface may be stored in advance in storage unit 34, or may be provided from dimming control device 20 via network 90. ​​Display unit 33 may be an interface for connecting an image display device to setting information input device 30. In this case, display unit 33 generates a video signal for displaying image data, and outputs the video signal to the image display device connected to itself.

[0036] The storage unit 34 is configured using a storage device such as a magnetic hard disk device, a semiconductor storage device, etc. The storage unit 34 stores information used by the control unit 35.

[0037] The control unit 35 is configured using a processor such as a CPU and a memory. The control unit 35 functions as a communication control unit 351 and a display control unit 352 by the processor executing a program. All or part of the functions of the control unit 35 may be realized using hardware such as an ASIC, a PLD, or an FPGA. The above program may be recorded on a computer-readable recording medium. The computer-readable recording medium is, for example, a portable medium such as a flexible disk, a magneto-optical disk, a ROM, a CD-ROM, or a semiconductor storage device (e.g., SSD), or a storage device such as a hard disk or a semiconductor storage device built into a computer system. The above program may be transmitted via an electric communication line.

[0038] The communication control unit 351 controls communication with the dimming control device 20 via the communication unit 31. For example, the communication control unit 351 receives data from the dimming control device 20 and passes the received data to the display control unit 352. For example, the communication control unit 351 transmits the data passed from the display control unit 352 to the dimming control device 20.

[0039] The display control unit 352 displays a user interface screen on the display unit 33 based on graphical user interface data obtained from the storage unit 34 or the dimming control device 20. The display control unit 352 obtains operation information indicating the result of an operation performed by the user on the displayed user interface via the operation unit 32, and passes information obtained in accordance with the operation information to the communications control unit 351. This information is transmitted to the dimming control device 20 by the communications control unit 351. The display control unit 352 may calculate individual setting values ​​for each lighting device 10 in accordance with input values ​​for each lighting set or each group input in response to a user operation. In this case, the calculated values ​​are transmitted to the dimming control device 20 by the communications control unit 351.

[0040] 5 is a diagram showing a specific example of a graphical user interface displayed on the display unit 33. On the screen, one or more template buttons 41, a map image 42, multiple lighting set images 43, a lighting set management button group 45, a group management button group 46, an illuminance operation area 47, a color tone operation area 48, and a save button 49 are displayed.

[0041] Each template button 41 is an image indicating a template. For example, in the example of Fig. 5, a character string indicated by the label information of each template is displayed in an area of ​​each template button 41. Each template button 41 has a different display mode. For example, the color of the area of ​​each template button 41 may be different.

[0042] The map image 42 shows an image showing a map showing a part or the whole of the target facility. In the area inside the map image 42, images showing the lighting fixtures 10 corresponding to their installation positions and images showing the lighting sets are displayed. In this embodiment, a lighting set image 43 is displayed for each lighting set. A label (identification information) is given to each lighting set, and the label is also displayed in the lighting set image 43. For example, at the position of the lighting set image 43 shown as L1, four lighting fixtures 10 of the lighting set given the label L1 are installed. The display mode of each lighting set image 43 is a display mode corresponding to the template set for that lighting set. For example, the template of a hanging scroll is set for the lighting set at the position of the lighting set image 43 displayed in the same display mode as the display mode of the hanging scroll of the template button 41.

[0043] A user can easily set a template for each lighting set by operating the template button 41 and the lighting set image 43. Any specific operation method may be implemented. For example, a template may be set for a lighting set at a position of a lighting set image 43 by dragging the template button 41 to be applied to that position. In this case, the display control unit 352 transmits operation information related to the drag and information related to a combination of a template and a lighting set to the dimming control device 20 via the communication control unit 351. The setting support unit 232 of the dimming control device 20 records in the template information storage unit 222 that the designated template is to be applied to the designated lighting set in accordance with the received information.

[0044] The lighting set management button group 45 includes a user interface for performing an operation to set a plurality of lighting sets as a group. For example, the lighting set management button group 45 includes buttons (in FIG. 5, buttons L1 to L8) indicating some or all of the lighting sets displayed on the map image 42, a select all check box, and a create group button. When setting a new group, the user operates each button indicating the lighting sets to be included in the group to select them, and then operates the create group button to generate a group including the lighting sets selected at that time. When the select all check box is selected, all lighting sets displayed on the map image 42 can be selected at once.

[0045] The group management button group 46 includes a user interface for performing operations to manage multiple groups. For example, the group management button group 46 includes buttons (buttons G1 to G4 in FIG. 5) that indicate some or all of the groups displayed on the map image 42, and a group deletion button. When the user wants to delete a group, he or she operates the button for the group to be deleted to select it, and then operates the group deletion button to delete one or more groups that were selected at that time.

[0046] Illuminance operation area 47 displays a user interface for operating the illuminance of lighting device 10. For example, a user can set the illuminance of lighting device 10 being operated by operating operation bar 471, operation bar 472, up button 473, and down button 474. The illuminance value determined in response to the operation of the operation bars and buttons (473, 474) is displayed in illuminance value display area 475. For example, the illuminance may be displayed as a percentage of the maximum illuminance of lighting device 10 (e.g., 0% to 100%), or as an absolute value of the illuminance (tone value). In the example of FIG. 5, both the percentage and the absolute value are shown. However, only one of the percentage and the absolute value may be displayed.

[0047] A user interface for manipulating the color tone of the lighting device 10 is displayed in the color tone operation area 48. For example, the user can set the color tone of the lighting device 10 being operated by operating the operation bar 481 or the up button or down button. The color tone value determined in response to the operation of the operation bar or button is displayed in the color tone value display area 482. For example, the color tone may be represented by a color temperature value or another value.

[0048] Save button 49 is a button for setting the illuminance and color tone values ​​currently indicated in the illuminance operation area 47 and color tone operation area 48 for the lighting device 10 that is the target of operation at the time the save button 49 is operated. In response to the save button 49 being operated, the display control unit 352 transmits information indicating the setting target and information indicating the setting value to the dimming control device 20. The information indicating the setting target may be information indicating an individual lighting device 10, information indicating a lighting set, or information indicating a group. The information indicating the setting value may be a setting value for an individual lighting device 10, a value set for the lighting set, or a value set for the group.

[0049] A user can operate (change or set) the illuminance and color tone of the selected lighting fixtures 10, the selected lighting set, or all the lighting fixtures 10 included in the selected lighting set or group collectively by selecting one or more lighting fixtures 10, one or more lighting sets, or one or more groups. For example, the user selects a button indicating a lighting fixture, lighting set, or group for which the user wants to set the illuminance and color tone on the map image 42, the lighting set management button group 45, or the group management button group 46. This operation selects the setting target. Then, the user operates the illuminance operation area 47 or the color tone operation image 48. This operation collectively sets all the lighting fixtures 10 included in the selected lighting set or group. At this time, the relative relationship (ratio) of the illuminance of all the lighting fixtures 10 included in the selected lighting set or group remains fixed, and the illuminance value is changed. For example, downlights (lighting fixtures 10) may be distributed in a plane, and the illuminance may be changed at each location, and then the illuminance value may be changed while maintaining the relative relationship (ratio) of each. For example, in the case of indirect lighting, the illuminance value may be set by fine-tuning each of the lighting fixtures 10 arranged in a line, taking into consideration the presence or absence of walls or beams, and then the illuminance value may be changed while maintaining the relative relationship (ratio) between each of them.

[0050] FIG. 6 is a diagram showing a specific example of a template generation screen. In the example shown in FIG. 6, each lighting fixture 10 included in one lighting set is displayed as an image according to its installation position on the left side. On the right side, an illuminance operation area 61 for setting the illuminance and color tone of each lighting fixture 10, a collective illuminance operation area 62 for collectively setting the illuminance of all lighting fixtures included in one lighting set, and a collective color tone operation area 63 for collectively setting the color tone of all lighting fixtures included in one lighting set are shown. Template information can be generated on this template generation screen. Note that the operation area for setting the color tone (color tone operation area 63) does not have to be displayed on the template generation screen. In other words, the template generation screen may be configured so that only the illuminance of the lighting fixtures can be collectively set.

[0051] For example, illuminance operation area 61_1 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_1, illuminance operation area 61_2 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_2, illuminance operation area 61_3 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_3, and illuminance operation area 61_4 is an illuminance operation area 61 for setting the illuminance of lighting fixture 10_4. By operating the operation bar in each illuminance operation area 61, it is possible to set the illuminance of lighting fixture 10 corresponding to each illuminance operation area 61. By operating these illuminance operation areas 61, it is possible to set the relative illuminance relationship of each lighting fixture 10 included in the lighting set of the template to be generated.

[0052] The summary illuminance operation area 62 is an operation area for changing the overall brightness while maintaining the relative illuminance relationships currently set by each illuminance operation area 61. The summary color tone operation area 63 is an operation area for setting the color tone of each lighting fixture 10 included in the lighting set of this template. By operating the summary color tone operation area 63, the color tone of each lighting fixture 10 included in the lighting set is set to the same value.

[0053] In the dimming control system 100 configured in this manner, the illuminance values ​​of multiple lighting fixtures 10 can be changed collectively while maintaining the relative relationships (ratios) between the illuminance values. For example, the illuminance values ​​of each lighting fixture 10 included in a lighting set can be changed while maintaining the relative relationships between the illuminance values. Generally, an optimal lighting environment is achieved by combining multiple lighting fixtures. As described above, the illuminance of multiple lighting fixtures 10 can be changed collectively while maintaining the relationships (ratios) between the combination of multiple lighting fixtures, which reduces the labor required for the work and enables appropriate illuminance settings.

[0054] In addition, in the dimming control system 100, by defining a template, it is possible to easily set the illuminance and color tone of each lighting fixture 10 by applying the template to each combination of multiple lighting fixtures (for example, a lighting set). In addition, information indicating the situation in which the template is used can be defined as label information of the template. For example, information indicating the type of exhibit may be given. By defining the template in this way, it is possible to easily select a template according to the purpose and set the illuminance of multiple lighting fixtures. In general, it is necessary to adjust the illuminance of each lighting fixture according to a detailed lighting production (how it is presented) that matches the exhibit. Furthermore, the illuminance of the exhibit is strictly controlled, and it is essential to show the exhibit and to adjust the illuminance finely. Even in such an environment, it is possible to easily perform settings according to the exhibit by applying the template of the dimming control system 100. Note that the specific example of the template shown in FIG. 6 is merely an example, and other types of templates may be defined. For example, a template for wall washer lighting or the like may be defined.

[0055] (Modification) The dimming control device 20 does not necessarily have to be configured as a single device. For example, the dimming control device 20 may be configured using a plurality of information processing devices. The plurality of information processing devices constituting the dimming control device 20 may be communicably connected via a communication path such as a network 90, and may be configured as a system such as a cluster machine or a cloud. For example, the recording control unit 231 and the setting support unit 232 may be realized in a computer installed at a position away from the target facility via a communication path such as the network 90, and the lighting control unit 233 may be realized in a computer installed in the target facility. In this case, the computer functioning as the lighting control unit 233 may be, for example, an information processing device such as a personal computer, or may be realized using a simple information processing device such as a single board computer. The dimming control device 20 and the setting information input device 30 may be configured as an integrated information processing device.

[0056] When manipulating (changing or setting) the illuminance of multiple lighting devices 10 collectively, the illuminance may be changed by fixing the magnitude relationship between each of the lighting devices 10, rather than fixing the relative relationship (ratio) of the illuminance of all the lighting devices 10 included in the group. For example, the magnitude relationship may be maintained, and the extent or ratio of the change in illuminance of each lighting device 10 may vary depending on the values ​​before and after the change. A specific example will be described below. Lighting fixture 10_1: 100% of maximum illumination Lighting fixture 10_2: 80% of maximum illumination Lighting fixture 10_3: 30% of maximum illumination Lighting fixture 10_4: 10% of maximum illumination

[0057] When the illuminance of each lighting device is set as above, the ratio of 10:8:3:1 may be changed while maintaining the magnitude relationship. For example, when the illuminance of these four lighting devices 10 is lowered, the values ​​may be changed as follows: Lighting fixture 10_1: 50% of maximum illumination Lighting fixture 10_2: 45% of maximum illumination Lighting fixture 10_3: 22% of maximum illumination Lighting fixture 10_4: 8% of maximum illumination

[0058] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and designs that do not deviate from the gist of the present invention are also included. [Explanation of symbols]
