[Embodiment]
First, with reference to FIG. 1, the outline | summary of the illuminating device 10 which concerns on embodiment is demonstrated. FIG. 1 is a view showing an outline of a lighting device 10 according to the embodiment. In addition, below, the case where the illuminating device 10 which concerns on embodiment makes exhibition objects, such as a picture, irradiation object, for example in a museum, a museum, etc. is demonstrated.

  In museums and museums, it is necessary to adjust the lighting for the exhibits every time they are replaced. In particular, when the lighting device is attached to a ceiling, the worker needs to work at a high place such as adjusting the direction of illumination of the lighting device by climbing on a stepladder.

  On the other hand, there is a lighting device capable of adjusting the radiation direction by remote control such as wireless. In such a lighting device, although work at a high place by the worker becomes unnecessary, the lighting direction of each lighting device needs to be adjusted individually by the worker. Therefore, there is room for improvement in simplifying the adjustment of the illumination direction of the illumination device.

  Therefore, the illumination device 10 according to the embodiment detects the irradiation area to be irradiated and drives the irradiation direction toward the irradiation area. Moreover, the illumination device 10 according to the embodiment makes it possible to determine which illumination device 10 illuminates the irradiation region with the plurality of illumination devices 10.

  That is, the illumination device 10 according to the embodiment determines the illumination device 10 that is optimal for the illumination area designated by the worker among the plurality of illumination devices 10. Then, the optimal illumination device 10 drives the irradiation direction to irradiate the irradiation area.

  In the example shown in FIG. 1, the case where two pictures are irradiation areas is shown, and two lighting devices 10 light the picture in the front in the drawing from the front in the drawing, and the lighting device 10 in the back is the back in the drawing. It shows the case of irradiating the painting on the side.

  As described above, in the lighting device 10 according to the embodiment, the operator only needs to designate the irradiation area, so that the adjustment of the irradiation direction can be simplified.

  Next, the structure of the illuminating device 10 which concerns on embodiment using FIG. 2 is demonstrated. FIG. 2 is a view showing a configuration example of the lighting device 10 according to the embodiment.

  As shown in FIG. 2, the lighting device 10 includes a base 20, a drive unit 30, a lighting unit 40, and a control unit 50. The base 20 is fixed to a mounting portion 5 such as a writing rail, for example. The base 20 is formed in, for example, a rectangular shape in appearance, and the control unit 50 is accommodated inside.

  The lighting rail shown in FIG. 2 is a part, and the lighting device 10 is shown fixed to the lighting rail. In addition, the lighting rail has a power line, and the current flowing through the power line is a power source of the lighting device 10.

  The drive unit 30 includes a first drive unit 31 and a second drive unit 32. The drive unit 30 adjusts the irradiation direction of the illumination unit 40 by rotating the first drive unit 31 and the second drive unit 32 based on the control of the control unit 50.

  Specifically, the first drive unit 31 and the second drive unit 32 are respectively configured by a motor and a gear (not shown). The first drive unit 31 adjusts the pan direction of the illumination unit 40 by rotating around the rotation axis C1 in the vertical direction. The second drive unit 32 adjusts the tilt direction of the illumination unit 40 by rotating around a rotation axis C2 orthogonal to the rotation axis C1.

  The illumination unit 40 has a light source such as a fluorescent lamp or an LED ((Light Emitting Diode)). The illumination unit 40 lights up according to the control of the control unit 50. In the illumination unit 40, the irradiation direction is defined by the drive unit 30.

  The control unit 50 is a controller that controls each unit of the lighting device 10, and is realized by, for example, a microprocessor or the like. The details of the control unit 50 will be described later with reference to FIG.

  Next, a specific example of the internal configuration of the lighting apparatus 10 according to the embodiment will be described with reference to FIG. FIG. 3 is a block diagram of the lighting device 10 according to the embodiment.

  As shown in FIG. 3, the lighting device 10 according to the embodiment further includes a communication unit 11, a sensor unit 15, and a storage unit 60 in addition to the drive unit 30, the illumination unit 40, and the control unit 50 described above. .

  The communication unit 11 is a communication module that communicates with other lighting devices 10, a management terminal managed by a worker, and the like. In the present embodiment, the communication unit 11 can use at least one of wired and wireless communication methods.

  The sensor unit 15 detects information indicating an irradiation area to be irradiated. The sensor unit 15 is, for example, an infrared sensor that detects an infrared ray, and detects positional information of the irradiation area, an irradiation condition to the irradiation area, and the like from the marker M disposed in the vicinity of the irradiation area. Here, a specific example of the process by the sensor unit 15 will be described using FIGS. 4 to 6.

  FIG. 4 is a diagram showing a specific example of the detection process of the marker M according to the embodiment. FIG. 5 is a view showing a specific example of the irradiation area Ri according to the embodiment. FIG. 6 is a view showing a specific example of irradiation conditions according to the embodiment.

  As shown in FIG. 4, the sensor unit 15 detects the infrared ray emitted from the marker M to detect the marker M. For example, the worker places the marker M in the vicinity of the display object to be irradiated (in the example shown in FIG. 4, the upper part of the display object) and turns on the marker M, that is, emits infrared light.

  Thereby, infrared rays are emitted from the marker M, and the sensor unit 15 detects such infrared rays. At this time, the sensor unit 15 can obtain the angle θ at which the marker M exists from the arrival direction of the infrared light, and can obtain the distance L1 to the marker M from the reception intensity of the infrared light.

  The sensor unit 15 also derives the relative position with respect to the marker M by calculating the horizontal distance L2 and the vertical distance h1 based on the distance L1 and the angle θ of the marker M with respect to the vertical direction. Then, the sensor unit 15 specifies the irradiation area Ri based on the infrared ray emitted from the marker M.

  Specifically, the sensor unit 15 can specify a range set in advance with the position of the marker M as a reference as the irradiation area Ri. The example shown in FIG. 5 shows the case where the predetermined range in which the marker M is at the upper end center of the irradiation area Ri is the irradiation area Ri.

  The operator can also designate the irradiation area Ri by changing the infrared radiation pattern (for example, the on / off cycle, the wavelength, and the like) of the marker M. For example, the worker can specify the emission pattern according to the irradiation area Ri corresponding to the number of the picture. And the sensor part 15 can identify the magnitude | size of designated irradiation area | region Ri based on this radiation | emission pattern.

  The sensor unit 15 can also detect the irradiation condition for the irradiation area Ri using infrared communication with the marker M. For example, as shown in FIG. 6, such irradiation conditions include an incident angle Rθ with respect to the irradiation area Ri and an irradiation prohibited area Rp which prohibits irradiation.

  The incident angle Rθ and the irradiation inhibition area Rp can be arbitrarily set by the operator. Moreover, it is also possible to set the illumination intensity which illuminates radiation range Ri, color temperature, the number of illuminations etc. as radiation conditions.

  For example, the operator can set two illumination numbers as the irradiation condition, and set different illuminances and color temperatures for one lighting device 10 and the other lighting device 10. Further, for example, it is also possible to divide the irradiation area Ri into a plurality of areas and to set the illuminance and the color temperature for each area.

  In addition, for example, the sensor unit 15 acquires information on the irradiation target and the exhibit from the marker M, and the lighting device 10 can also irradiate the irradiation area Ri so as to be the irradiation mode suitable for the exhibit. is there. In other words, the illumination device 10 can also irradiate the irradiation target in the irradiation mode according to the type of the irradiation target.

  Specifically, the illumination device 10 irradiates so that the illuminance is equal to or less than a predetermined threshold when the irradiation target is a picture, and irradiates so that the illuminance is equal to or more than the predetermined threshold when the irradiation target is pottery You may decide to do it.

  As described above, in the illumination device 10 according to the embodiment, the operator simply selects the type of the illumination target by setting the illumination mode according to the type of the illumination target in advance. It becomes possible to set to become an appropriate irradiation mode. Thereby, the operator's operation of the marker M can be simplified.

  In the above-mentioned example, although a case where sensor part 15 detects information about irradiation field Ri based on infrared rays emitted from marker M was explained, it is not limited to this.

  For example, the sensor unit 15 may detect an ultrasonic wave or a sound wave instead of infrared light, for example, the sensor unit 15 is configured by a camera, and the marker M is detected based on a camera image captured by the camera. You may decide to do it.

  For example, the actual dimensions of the marker M may be registered in the sensor unit 15, and the relative position with the marker M may be determined based on the dimensions of the marker M appearing in the camera image and the actual dimensions. Alternatively, the sensor unit 15 may configure such a camera as a stereo camera, and use such stereo camera to determine the relative position with respect to the marker M.

  Alternatively, the sensor unit 15 may analyze the inside of the space by laser and detect the marker M. Furthermore, instead of the marker M, the sensor unit 15 may detect an exhibit by image analysis processing using a camera image, and identify the exhibit as the irradiation area Ri. That is, the sensor unit 15 can also detect the irradiation area Ri based on the display object to be irradiated instead of the marker M. Further, the sensor unit 15 may detect the area irradiated by the operator with the laser pointer as the irradiation area Ri instead of the marker M. Thus, the sensor unit 15 may not necessarily detect the marker M.

  Returning to the description of FIG. 3, the control unit 50 will be described. The control unit 50 has a program defining various processing procedures and the like, and an internal memory for storing required data, and executes various processings by these, and particularly as closely related to the present invention, The determination unit 51 and the adjustment unit 52 are provided.

  The determination unit 51 determines the lighting device 10 that emits the irradiation region Ri based on the information indicating the irradiation region Ri detected by the sensor unit 15 and the information detected by the sensor unit 15 included in the other lighting device 10. Do.

  First, the determination unit 51 calculates an irradiation mode in which the irradiation area Ri input from the sensor unit 15 can be irradiated by the illumination unit 40 of the own device. For example, as the irradiation mode, the determination unit 51 calculates each parameter such as the range that can be irradiated to the irradiation area Ri, the incident angle Rθ, the illuminance, and the color temperature.

  Subsequently, the determination unit 51 calculates the fulfillment rate of each parameter with respect to the irradiation condition. For example, the determination unit 51 calculates the fulfillment rate based on the parameter information 61 stored in the storage unit 60.

  For example, in the parameter information 61, each parameter such as an illumination range that can be illuminated by the illumination unit 40, illuminance, and color temperature is stored. For example, the irradiation area that can be irradiated is determined according to the drive area of the drive unit 30.

  That is, when the determination unit 51 drives the drive unit 30 (the first drive unit 31 and the second drive unit 32; see FIG. 2) such that the illumination unit 40 irradiates the irradiation region Ri, the determination unit 51 applies to the irradiation region Ri. The irradiation range of the illumination unit 40 is calculated.

  At this time, when the irradiation prohibited condition Rp is included in the irradiation condition, the determination unit 51 can also calculate the irradiation range which can irradiate the irradiation area Ri by avoiding the irradiation prohibited region Rp by the illumination unit 40. It is. Furthermore, when the incident angle Rθ is included in the irradiation condition, the determination unit 51 can also calculate whether the irradiation area Ri can be irradiated at the incident angle Rθ.

  Further, the determination unit 51 can calculate, for example, the illuminance capable of irradiating the irradiation area Ri with the illumination unit 40 based on the light emission intensity of the illumination unit 40 and the distance from the illumination unit 40 to the irradiation area Ri. For example, the determination unit 51 calculates the value of the illuminance to be larger as the distance to the irradiation region Ri decreases.

  In addition, the determination unit 51 is an illumination unit 40 necessary to irradiate the irradiation region Ri according to the distance from the illumination unit 40 to the irradiation region Ri (hereinafter also referred to as irradiation distance) or the size of the irradiation region Ri. Calculate the light distribution angle and the light emission intensity of Specifically, it is necessary to widen the light distribution angle as the irradiation distance is shorter, and it is necessary to narrow the light distribution angle as the irradiation distance is longer. Moreover, it is necessary to narrow the light distribution angle as the irradiation area Ri is smaller, and it is necessary to widen the light distribution angle as the irradiation area Ri is larger.

  Moreover, since the illumination intensity per unit area becomes smaller as the light distribution angle becomes wider, it is necessary to intensify the light emission intensity of the illumination unit 40. On the other hand, since the illuminance per unit area increases as the light distribution angle is narrowed, the light emission intensity of the illumination unit 40 needs to be weakened.

  And the determination part 51 calculates the fullness rate of the own apparatus with respect to irradiation conditions using said parameter. At this time, the determination unit 51 can calculate the fulfillment rate by, for example, weighting different for each parameter.

  That is, when importance is placed on the ratio of the irradiation range to the irradiation region Ri among the irradiation conditions, the determination unit 51 weights the irradiation range heavily to calculate the fulfillment rate, or places importance on the illumination weight when emphasizing the illuminance. It is possible to weigh and calculate the fulfillment rate.

  Subsequently, the determination unit 51 transmits the calculated fullness rate to the other lighting device 10 through the communication unit 11 and receives the fullness rate calculated by the other lighting device 10 through the communication unit 11.

  And the determination part 51 determines the illuminating device 10 which irradiates radiation range Ri by comparing each fullness rate. Here, the specific example of the process by the determination part 51 is demonstrated using FIGS. 7-9.

  7 to 9 are diagrams showing specific examples of the determination process by the determination unit 51 according to the embodiment. As illustrated in FIG. 7, the determination unit 51 determines the lighting device 10 that emits the irradiation area Ri by comparing the filling rates calculated by the plurality of lighting devices 10 a to 10 c.

  For example, when the fulfillment rate of the own device is the highest, the determination unit 51 determines the lighting device 10 that emits the irradiation region Ri as the own device. In the example shown in FIG. 7, since the fulfillment rate of the illumination device 10 b is the highest, the illumination device 10 b illuminates the illumination region Ri.

  That is, among the plurality of lighting devices 10, the lighting device 10 having the highest fulfillment rate with respect to the irradiation condition of the irradiation region Ri irradiates the irradiation region Ri. That is, in the lighting device 10 according to the embodiment, the radiation rate of the lighting device 10 suitable for radiating the radiation region Ri is calculated by comparing the filling rate of the own device with the filling rate of the other lighting devices 10. It will be assigned to Ri.

  In addition, the determination unit 51 may determine the lighting device 10 to be irradiated with the irradiation region Ri by comparing the distance from each lighting device 10 to the irradiation region Ri and other parameters without being limited to the fulfillment rate. .

  By the way, depending on the performance of each lighting device 10, the position of the radiation area Ri, and the like, there are cases where the lighting conditions of one radiation area Ri can not be satisfied with one lighting device 10. In such a case, the determination unit 51 sets a plurality of illumination devices 10 for emitting the irradiation region Ri.

  For example, as shown in FIG. 8, when none of the lighting devices 10 a to 10 c satisfies the fulfillment rate below a predetermined value (for example, 90%), the lighting device 10 emits the irradiation area Ri for the plurality of lighting devices 10. decide.

  The example shown in the figure shows the case where the fulfillment rate is 98% when the irradiation area Ri is irradiated with both the illumination device 10a (fill rate 40%) and the illumination device 10b (fill rate 70%). There is. As described above, when the fulfillment rate of each of the plurality of lighting devices 10 does not satisfy the predetermined value, the determining unit 51 may calculate the fill rate in the case of irradiating the irradiation region Ri with the plurality of lighting devices 10. it can.

  Then, when the fulfillment rate exceeds a predetermined value, that is, when the irradiation condition is satisfied, the determination unit 51 determines the plurality of lighting devices 10 as the lighting device 10 that irradiates the irradiation region Ri.

  That is, the illumination device 10 according to the embodiment cooperates with the plurality of illumination devices 10 and illuminates the illumination region Ri when the illumination condition is not satisfied by one illumination device 10. Thus, the illumination device 10 according to the embodiment can satisfy various illumination conditions by irradiating the irradiation region Ri with the plurality of illumination devices 10.

  By the way, when a plurality of irradiation areas Ri are set, the illumination apparatus 10 according to the embodiment irradiates the next irradiation area Ri excluding the illumination apparatus 10 determined as the illumination apparatus 10 for irradiating the irradiation area Ri. The lighting device 10 is determined.

  For example, as shown in FIG. 9, the case where the irradiation area Ri1 and the irradiation area Ri2 are set will be described. For example, after determining the lighting device 10 that emits the irradiation region Ri1, the determining unit 51 determines the lighting device 10 that emits the next irradiation region Ri2.

  Specifically, first, the determination unit 51 compares the sufficiency rate of each lighting device 10 with respect to the irradiation region Ri1. The example shown in the figure shows the case where the fulfillment rate of the lighting device 10a is higher than that of the other lighting devices 10b and 10c.

  Therefore, the determination unit 51 of the lighting device 10a determines the lighting device 10 as the lighting device 10 that emits the irradiation region Ri1. Here, the illumination device 10a is excluded from the candidates for the illumination device 10 that illuminates the next illumination region Ri2 in order to illuminate the illumination region Ri1.

  That is, as shown to the same figure, in the state which fixed the illuminating device 10a, the sufficiency rate with respect to radiation range Ri2 is compared with the illuminating device 10b and the illuminating device 10c except the illuminating device 10a. In the example shown in the figure, since the fulfillment rate of the illumination device 10b is higher than the fulfillment rate of the illumination device 10c, the illumination device 10b is determined as the illumination device 10 that illuminates the irradiation region Ri2.

  As described above, in the lighting device 10 according to the embodiment, the lighting device 10 that irradiates the next irradiation region Ri is determined excluding the lighting device 10 that irradiates the irradiation region Ri, with respect to the plurality of irradiation regions Ri. It becomes possible to assign an appropriate lighting device 10 to each.

  Note that, for example, when it is desired that the worker change the assignment of the lighting device 10 after the lighting devices 10 to be irradiated to the plurality of irradiation regions Ri are respectively determined, a reset instruction is given to the worker terminal (not shown) When input, it is also possible to determine the illumination device 10 that illuminates each of the illumination regions Ri again among the plurality of illumination devices 10.

  Returning to the description of FIG. 3, the adjustment unit 52 will be described. The adjustment unit 52 adjusts at least one of the illuminance, the light distribution angle, and the color temperature of the illumination unit 40. The adjustment unit 52 adjusts the illuminance and the light distribution angle of the illumination unit 40 so as to match the irradiation condition.

  Further, when the illumination unit 40 includes a plurality of light sources having different color temperatures, the adjustment unit 52 can adjust the light emission intensities of the plurality of light sources such that the color temperature corresponds to the irradiation condition. Moreover, in the illuminating device 10 which concerns on embodiment, it is also possible to set the time-sequential change of an illumination aspect as irradiation conditions.

  For example, the operator can set an irradiation condition such that the irradiation area Ri becomes brighter gradually, an illumination condition such that the color temperature changes in time series, and an irradiation condition such that the irradiation area Ri blinks .

  In such a case, the adjustment unit 52 can also adjust the illuminance and the color temperature of the illumination unit 40 according to the irradiation condition. As described above, the adjustment unit 52 can adjust the illumination and the color temperature according to the irradiation condition to satisfy the variety-rich irradiation condition.

  The drive unit 30 drives the illumination unit 40 so as to satisfy a predetermined irradiation condition. The drive unit 30 drives the first drive unit 31 and the second drive unit 32 (see FIG. 2) based on the parameters instructed from the determination unit 51. That is, the drive unit 30 drives the illumination unit 40 so as to irradiate the irradiation region Ri, when the own device is determined to be the illumination device 10 that irradiates the irradiation region Ri.

  Next, a processing procedure performed by the lighting device 10 according to the embodiment will be described with reference to FIG. Drawing 10 is a flow chart which shows the processing procedure which lighting installation 10 concerning an embodiment performs.

  As shown in FIG. 10, first, the sensor unit 15 detects information on the irradiation region Ri (step S101). Subsequently, the sensor unit 15 acquires the irradiation condition of the irradiation area Ri (step S102).

  Subsequently, the determination unit 51 calculates the filling rate for the irradiation condition (step S103), and compares the filling rate with the filling rate of the other lighting devices 10 (step S104). Subsequently, the determination unit 51 determines whether the fulfillment rate of the own device is the largest (step S105).

  Here, when the fulfillment rate of the own device is the maximum (step S105, Yes), the determination unit 51 determines the illumination device 10 to irradiate the irradiation area Ri for the own device, and the drive unit 30 determines the illumination unit 40. After driving (step S106), the process ends.

  On the other hand, when the fulfillment rate of the own device is not the maximum (No at step S105), the determination unit 51 determines whether the illumination condition is satisfied by the other lighting devices 10 (step S106). If the illumination condition is not satisfied by another illumination device 10 (step S107, No), the drive unit 30 drives the illumination unit 40 (step S106) when the illumination condition including the own device is satisfied. Finish.

  Moreover, the illumination device 10 ends the process when the illumination condition is satisfied by another illumination device 10 (step S107, Yes).

  As described above, the illumination device 10 according to the embodiment is an illumination device having the drive type illumination unit 40, and includes the sensor unit 15, the determination unit 51, and the drive unit 30. The sensor unit 15 detects information indicating an irradiation area Ri to be irradiated. The determination unit 51 determines the lighting device 10 that irradiates the irradiation area Ri based on the information detected by the sensor unit 15 and the information detected by the sensor unit 15 included in the other lighting device 10. The drive unit 30 drives the illumination unit 40 so as to irradiate the irradiation area Ri, when the own device is determined to be the illumination apparatus 10 for irradiating the irradiation area Ri. Thereby, in the illumination device 10 according to the embodiment, the operator only has to designate the irradiation area Ri, so that the adjustment of the irradiation direction can be simplified.

  Further, in the embodiment described above, the drive unit 30 drives the illumination unit 40 so as to satisfy a predetermined irradiation condition. As a result, since the irradiation area Ri is irradiated so as to satisfy the irradiation condition, it is possible to appropriately respond to the request of the worker.

  Further, in the embodiment, the determining unit 51 compares the irradiation mode in which the own device can irradiate the irradiation area Ri with the irradiation mode in which the other lighting devices 10 can irradiate, and irradiates the irradiation area Ri. Decide. Thereby, it can be determined as the lighting device 10 which irradiates the irradiation area Ri for the appropriate lighting device 10.

  Further, in the embodiment, the determination unit 51 determines the illumination device 10 that illuminates the illumination region Ri for the illumination device 10 having a high fulfillment rate to the illumination condition among the own device and the other illumination devices 10. Thereby, it can be determined to be the lighting device 10 that irradiates the lighting area Ri to the appropriate lighting device 10.

  Further, in the embodiment, when the irradiation condition is satisfied by the plurality of lighting devices 10, the determination unit 51 determines the lighting device 10 that irradiates the irradiation region Ri for the plurality of lighting devices 10. Thereby, since irradiation field Ri is irradiated with a plurality of lighting installation 10, a fullness rate to irradiation conditions can be raised.

  Further, in the embodiment, the determination unit 51 determines the lighting device 10 that can irradiate the irradiation area Ri with respect to the lighting device 10 capable of irradiating the irradiation area Ri while avoiding the irradiation prohibited area Rp included in the irradiation condition. Thereby, it can be determined to be the lighting device 10 that emits the irradiation area Ri for the lighting device 10 close to the request of the worker.

  Further, in the embodiment, when there is a plurality of irradiation regions Ri, the determination unit 51 except the lighting device 10 determined as the lighting device 10 that irradiates the irradiation region Ri is the lighting device 10 that irradiates the next irradiation region Ri. Decide. As a result, since the lighting device 10 to which the irradiation area Ri is assigned does not irradiate the other irradiation areas Ri, the lighting devices 10 can be appropriately allocated to the respective irradiation areas Ri.

  In the embodiment, the sensor unit 15 detects the irradiation area Ri based on the position of the marker M disposed in the irradiation area Ri. As a result, the worker only needs to change the position of the marker M, so the work of the worker can be simplified.

  Moreover, the embodiment further includes an adjustment unit 52 that adjusts at least one of the illuminance and the color temperature of the illumination unit 40. Thereby, since the variation of the irradiation aspect can be increased, it can respond to various irradiation conditions.

  By the way, although the case where the illuminating device 10 makes a display object irradiation target was demonstrated in embodiment mentioned above, it is not limited to this. That is, for example, the lighting device 10 can also be used as a general lighting device. In addition, when the sensor unit 15 is configured by a camera, the illumination device 10 may track and track a person to be illuminated. In other words, the illumination device 10 can use any object to be irradiated. Moreover, although the case where the illuminating device 10 was installed in the attaching part 5 (refer FIG. 2) attached to the ceiling was demonstrated in embodiment mentioned above, the illuminating device 10 is attached to the attaching part 5 attached to a floor or a side wall. It may be installed.

  Moreover, although embodiment mentioned above demonstrated the case where the illuminating device 10 was fixed and installed, it is not limited to this. For example, the lighting device 10 may be installed to drive on a rail. Thereby, since the range which can be irradiated by the illuminating device 10 can be expanded, it becomes possible to satisfy various irradiation conditions.

  Although the embodiments of the present invention have been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. This embodiment and its modifications are included in the invention described in the claims and the equivalents thereof as well as included in the scope and the gist of the invention.
