(First embodiment)
FIG. 1 is a block diagram illustrating a functional configuration of the display device 10 according to the first embodiment. FIG. 2 is a diagram illustrating a main part of the elevator 20 in which the display device 10 is used. The display device 10 according to the present embodiment includes a display unit 150, a boarding time storage unit 160, a time determination unit 130, and an information determination unit 140. The display unit 150 is attached to the inner surface of the car 22 of the elevator 20. The boarding time storage unit 160 stores person identification information for identifying persons with each other in association with time specifying information. The time specifying information is information for specifying the time that the person is supposed to board the car 22. The time determination unit 130 acquires the person identification information of the passenger who has boarded the car 22, and uses the acquired person identification information and the boarding time storage unit 160 to estimate the time when the passenger will board the car 22 ( Hereinafter, it is described as an assumed time). The information determination unit 140 determines information to be displayed on the display unit 150 using the estimated time determined by the time determination unit 130. Details will be described below.

  As described above, the display unit 150 is attached to the inner surface of the car 22 of the elevator 20 and displays information to be shown to the passengers who are on the car 22. This information is information on a building (for example, a building) in which the elevator 20 is installed, an advertisement, and the like, and is stored in the information storage unit 170 included in the display device 10. The information storage unit 170 stores a plurality of information. And the information determination part 140 determines the information displayed on the display part 150 among the information memorize | stored in the information storage part 170 using the assumption time which the time determination part 130 determined. As described above, the estimated time is a time when the passenger is assumed to board the car 22. And the information determination part 140 selects the information which a display is complete | finished within this assumption time, for example, and displays it on the display part 150. FIG.

  The information stored in the information storage unit 170 is updated repeatedly (for example, periodically) by the information update unit 175 included in the display device 10. For example, the information update unit 175 reads information stored in the information server 30 outside the display device 10 and stores the information in the information storage unit 170. Note that the information stored in the information server 30 is also updated repeatedly (for example, periodically), but the update frequency of the information storage unit 170 by the information update unit 175 is lower than the update frequency of the information server 30. For example, when the information stored in the information server 30 is updated every day, the information stored in the information storage unit 170 is updated every week. However, the update frequency of the information server 30 and the update frequency of the information storage unit 170 are not limited to the above example.

  The display device 10 further includes an imaging unit 110, an image analysis unit 120, and a boarding time update unit 165.

  The imaging unit 110 captures the inside of the car 22 of the elevator 20 and generates image data. In other words, the imaging unit 110 images the face of a person who has boarded the car 22. The frame rate of the image captured by the imaging unit 110 is arbitrary. For example, the frame rate may be a rate that constitutes a moving image (for example, 29 frames / second or more), or a rate that does not constitute a moving image (for example, 15 frames / second or less).

  The image analysis unit 120 analyzes the image data generated by the imaging unit 110. As an example, the image analysis unit 120 performs a feature amount extraction process. The feature amount extracted here includes a feature amount for individually identifying a human face.

  The time determination unit 130 determines the estimated time using the feature amount extracted by the image analysis unit 120. Details of the processing performed by the time determination unit 130 will be described later using a flowchart.

  The boarding time update unit 165 updates the information stored in the boarding time storage unit 160 by using the elevator usage record for each person. The use results of the elevators by person are generated by using the analysis result of the image analysis unit 120, for example. Details of the processing performed by the boarding time updating unit 165 will be described later using a flowchart.

  As shown in FIG. 2, the elevator 20 includes a control unit 24. The control unit 24 controls the vertical movement of the car 22 using information output from the operation unit 26 provided on the inner surface of the car 22. The information output from the operation unit 26 includes information indicating at which floor the car 22 should be stopped.

  FIG. 3 is a diagram illustrating an example of a data configuration of information stored in the boarding time storage unit 160 in a table format. In the example shown in the figure, the boarding time storage unit 160 stores time specifying information for each person identification information. The time specifying information is information indicating a value obtained by statistically processing past boarding times, for example. Examples of the statistical process include, but are not limited to, an average value calculation process, a mode value calculation process, a minimum value specifying process, and a maximum value specifying process. In the person who lives or works in the building where the elevator 20 is installed, the floor to get on and the floor to get off are often determined. In such a case, the accuracy of the time specifying information stored in the boarding time storage unit 160 is increased.

  Furthermore, the boarding time storage unit 160 may store information indicating the boarding performance on the elevator 20 (hereinafter referred to as boarding performance information) for each person identification information. The boarding result information includes information indicating the boarding date and information indicating the boarding time. This boarding result information is generated using an analysis result by the image analysis unit 120, as will be described later. Note that the data configuration of the information stored in the boarding time storage unit 160 is not limited to the example shown in the figure.

  FIG. 4 is a diagram illustrating an example of a data configuration of information stored in the information storage unit 170 in a table format. In the example shown in this figure, the information storage unit 170 stores information to be displayed (display data) and links the display data with the length of time to display the display data (moving image data). In the case of playback time). The information storage unit 170 may further store target attributes of information to be displayed (for example, gender and age group) in association with display data. The display data may be still image data or moving image data.

  FIG. 5 is a diagram illustrating an example of a hardware configuration of the display device 10. The main configuration of the display device 10 is realized using an integrated circuit. This integrated circuit includes a bus 402, a processor 404, a memory 406, a storage device 408, an input / output interface 410, and a network interface 412. The bus 402 is a data transmission path through which the processor 404, the memory 406, the storage device 408, the input / output interface 410, and the network interface 412 transmit / receive data to / from each other. However, the method of connecting the processors 404 and the like is not limited to bus connection. The processor 404 is an arithmetic processing unit realized using a microprocessor or the like. The memory 406 is a memory realized using a RAM (Random Access Memory) or the like. The storage device 408 is a storage device realized using a ROM (Read Only Memory), a flash memory, or the like.

  The input / output interface 410 is an interface for connecting the bus 402 to a device. In this figure, an imaging device 414 and a display device 416 are connected to the input / output interface 410. The imaging device 414 is an example of the imaging unit 110 in FIG. 1, and the display device 416 is an example of the display unit 150 in FIG.

  The network interface 412 is an interface for connecting the display device 10 to an external communication network. A method of connecting the network interface 412 to the communication network may be a wireless connection or a wired connection.

  The storage device 408 stores a program module for realizing each functional element of the display device 10. The processor 404 implements each function of the display device 10 by reading this program module into the memory 406 and executing it.

  The hardware configuration of the integrated circuit described above is not limited to the configuration shown in this figure. For example, the program module may be stored in the memory 406. In this case, the integrated circuit may not include the storage device 408.

  Note that each element of the display device 10 illustrated in FIG. 5 may be housed in one housing. In this case, the display device 10 is a tablet-type terminal, for example, and can be attached to the inner surface of the car 22 later. In this case, the imaging unit 110, the image analysis unit 120, the time determination unit 130, the information determination unit 140, the display unit 150, the boarding time storage unit 160, the boarding time update unit 165, the information storage unit 170, and the information update of the display device 10 The part 175 is provided in the car 22.

  Further, the imaging device 414 may be a surveillance camera attached to the car 22 in advance. The display device 416 may be a display device that is attached to the car 22 in advance.

  In addition, at least one of the image analysis unit 120, the information determination unit 140, the display unit 150, the boarding time storage unit 160, the boarding time update unit 165, the information storage unit 170, and the information update unit 175 of the display device 10 illustrated in FIG. The part may be located outside the car 22. The functional elements located outside the car 22 are realized using, for example, a cloud type device.

  FIG. 6 is a flowchart illustrating an example of processing performed by the display device 10. In the example shown in this flowchart, the display device 10 uses a facial feature amount as human identification information.

  When the car 22 arrives at the target floor, the control unit 24 of the elevator 20 stops the car 22 and then opens the door of the car 22 and the door of the floor. Then, a person gets on the car 22. The imaging unit 110 generates image data including the face of a person who has boarded the car 22 (hereinafter referred to as a passenger) and outputs the image data to the image analysis unit 120 of the display device 10. The image analysis unit 120 generates a facial feature amount included in the image data (step S20). At this time, the image analysis unit 120 may further determine the attributes of the passenger, such as sex and age group.

  Next, the time determination unit 130 of the display device 10 uses the feature amount corresponding to the feature amount generated by the image analysis unit 120, that is, the feature amount having the highest degree of matching, from the feature amount stored in the boarding time update unit 165. select. And the time determination part 130 reads the time specific information linked | related with the selected feature-value from the boarding time update part 165 (step S40). Then, the time determination unit 130 determines the estimated time using the read time specifying information (step S60). For example, when the time specifying information indicates a statistically processed value of the past boarding time, the time determination unit 130 sets this value as the assumed time. However, the time determination unit 130 may use a value obtained by subtracting a predetermined value from the value indicated by the time specifying information or a value obtained by multiplying a value indicated by the time specifying information by a predetermined coefficient as the assumed time. The coefficient used here is, for example, more than 0 and 1 or less, but is not limited to this. For example, when the time specifying information is defined as a minimum value of past boarding times or a value close thereto, the above-described coefficient is, for example, 1 or more and N or less. Here, N is determined based on the floor number of the structure in which the elevator 20 is installed. For example, if the arc structure is 10 stories, N will be 10.

  Next, the information determination unit 140 of the display device 10 reads information to be displayed on the display unit 150 from the information storage unit 170 using the estimated time determined by the time determination unit 130, and outputs the read information to the display unit 150. (Step S80). For example, the information determination unit 140 selects the longest information from information whose display time is less than or equal to the estimated time. Further, when the information stored in the information storage unit 170 is advertisement information, and the information storage unit 170 stores each advertisement information in association with a display time and a unit price, the information determination unit 140 Information to be displayed may be selected / combined so that the total value of the displayed advertisement unit prices is maximized. Note that the unit price described above may vary depending on the cumulative number of advertisements displayed. In this case, the unit price stored in the information storage unit 170 reflects this variation as needed.

  In addition, when the image analysis unit 120 determines the attribute of the passenger, the information determination unit 140 selects information that matches the attribute determined by the image analysis unit 120 and then further performs selection processing using the assumed time. Is preferably performed.

  And the display part 150 displays the information received from the information determination part 140, and makes the passenger of the cage | basket | car 22 visually recognize.

  Note that the image analysis unit 120 also outputs the facial feature amount included in the image data to the boarding time update unit 165. The boarding time update unit 165 measures the boarding time of the passenger using the feature amount output from the image analysis unit 120 (step S100), and updates the boarding time storage unit 160 (step S120).

  Specifically, when a passenger gets in the car 22, the boarding time update unit 165 can recognize the feature amount of the passenger. Thereafter, when the passenger gets out of the car 22, the boarding time update unit 165 cannot recognize the feature amount of the passenger. The boarding time storage unit 160 recognizes the time during which the feature amount of a certain passenger has been recognized as the time that the passenger has been in the car 22, and adds this boarding time to the boarding result together with the boarding date and time. In addition, the information corresponding to the feature amount among the information stored in the boarding time storage unit 160 is updated. Furthermore, the boarding time update unit 165 updates the time specifying information using the updated boarding performance.

  The boarding time update unit 165 acquires information specifying information output to the display unit 150 from the information determination unit 140 and associates this information with the passenger identification information in the boarding time storage unit 160. It may be memorized. In this way, the information displayed on the display unit 150 is stored in the boarding time storage unit 160 for each passenger. In this case, the information determination unit 140 can select information to be displayed on the display unit 150 so that the same information is not displayed on the display unit 150 more than the reference number of times in step S80.

  In addition, on a specific floor such as the first floor, a plurality of passengers may get on at the same time. In this case, the image generated by the imaging unit 110 includes a plurality of passenger faces. Then, in step S20, the image analysis unit 120 generates a feature amount for each of the plurality of passengers. In this case, the time determination unit 130 reads the time specifying information corresponding to each of the plurality of feature amounts in step S40, and further determines the estimated time using the plurality of time specifying information in step S60. For example, the time determination unit 130 sets a temporary estimated time corresponding to each of the plurality of pieces of time specifying information, and sets the longest of the temporary estimated times as the assumed time. Note that the time determination unit 130 may set the shortest of the temporary estimated times as the estimated time.

  Moreover, the display apparatus 10 may specify the person boarding the elevator 20 using biometric information other than a face image. For example, the display device 10 may further include an audio data generation unit that generates audio data and an audio data analysis unit that analyzes the audio data. In this case, the display device 10 can also specify a person who is on the elevator 20 using voiceprint authentication. The display device 10 can also identify a person who is on the elevator 20 using both face authentication and voiceprint authentication.

  As described above, according to the present embodiment, the display device 10 determines information to be displayed on the display unit 150 by analyzing the image data generated by the imaging unit 110. Therefore, the time from when the passenger gets on the car 22 of the elevator 20 until the information starts to be displayed on the display unit 150 can be shortened. Moreover, since it is not necessary to communicate with the control part 24 of the elevator 20, the display apparatus 10 can be installed in the elevator 20 easily.

  In this embodiment, person identification information may be registered in advance in the boarding time storage unit 160. As such a case, when the elevator 20 is installed in a condominium, there is a case where the personal identification information of the resident of the apartment is registered in advance. In addition, when the elevator 20 is installed in an office building, there is a case in which person identification information of a person working in the office building is registered in advance. In this case, the information storage unit 170 may separately store information for people registered in the boarding time storage unit 160 and information for people not registered in the boarding time storage unit 160. . Then, when a person who is not registered in the boarding time storage unit 160 is in the car 22, the information determination unit 140 performs the above-described process even if there are other people registered in the boarding time storage unit 160. Alternatively, information for a person who is not registered in the boarding time storage unit 160 may be selected. However, when only a person who is not registered in the boarding time storage unit 160 is on the car 22, the information determination unit 140 does not perform the above-described processing and is for people who are not registered in the boarding time storage unit 160. Information may be selected.

(Second Embodiment)
The display device 10 according to the present embodiment has the same configuration as that of the display device 10 according to the first embodiment, except that information to be displayed can be changed according to time. Specifically, in this embodiment, the data configuration of the boarding time storage unit 160 is different from that of the first embodiment.

  FIG. 7 is a diagram illustrating a data configuration of the boarding time storage unit 160 in the present embodiment in a table format. In the present embodiment, the boarding time storage unit 160 stores time specifying information by time range (by time). Such a data structure is suitable, for example, when the elevator 20 is installed in an office building.

  For example, at times when people are expected to leave the office and when they are expected to leave the company, passengers often move between the floor where the entrance of the office building is located and the floor where the passenger's workplace is located. . On the other hand, at other times, the passenger often travels between the floor where the passenger's workplace is located and the floor where other people's workplace is located or where the conference room is located. For this reason, the boarding time memory | storage part 160 is the time range when the passenger is boarding the car 22 of the elevator 20 in the time range where it is assumed that a person goes to the office, the time range where it is assumed that he leaves the office, and other time ranges. The lengths of are likely to be different. In the present embodiment, the boarding time storage unit 160 stores different time specifying information for each time range in order to cope with this.

  And the time determination part 130 of the display apparatus 10 shows the time specific information corresponding to the present time among several time specific information linked | related with the feature-value of a passenger's face in step S60 of FIG. , Selecting from the boarding time storage unit 160. As a result, the information displayed on the display device 10 can change depending on the time.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. Further, the boarding time storage unit 160 stores time specifying information by time range (by time). For this reason, even if the assumed value of the length of time that the passenger is in the car 22 varies depending on the time, the display device 10 displays information that matches the estimated value of the boarding time at that time. 150 can be displayed.

(Third embodiment)
The display device 10 according to the third embodiment is the first implementation except for the data structure of the data stored in the boarding time storage unit 160, the generation process of the assumed time, and the update process of the boarding time storage unit 160. It is the structure similar to the display apparatus 10 which concerns on a form or 2nd Embodiment.

  FIG. 8 is a diagram illustrating a functional configuration of the display device 10 according to the present embodiment. As will be described later, the time specifying information includes not the length of time in which the car 22 has been boarded but the floor where the passenger is likely to get out of the car 22. And the time determination part 130 determines the time required for the movement between these floors to assumption time. In addition, the boarding time update unit 165 updates the boarding time storage unit 160 using the information acquired from the image analysis unit 120 and the information acquired from the control unit 24 of the elevator 20.

  Each diagram of FIG. 9 is a diagram showing a data configuration of the boarding time storage unit 160 in the present embodiment in a table format. In the present embodiment, the boarding time storage unit 160 stores two types of data.

  First, as shown in FIG. 9A, the boarding time storage unit 160 stores time specifying information and boarding results for each person identification information. The time specifying information indicates at least the floor where the person is likely to get off. Moreover, the boarding time memory | storage part 160 has memorize | stored the time required in order to move from a certain floor to another floor, as shown in FIG.9 (B). Then, the time determination unit 130 calculates the time required to move from the current floor, that is, the floor on which the passenger has boarded, to the floor indicated by the time specifying information, that is, the floor where the passenger is expected to get off. ) To determine the estimated time.

  In the example shown in FIG. 9A, the boarding time storage unit 160 stores a plurality of floors (for example, two) as time specifying information for one person identification information. In this case, for example, the time determination unit 130 acquires, from the control unit 24, the current moving direction (upward or downward) of the car 22 and the current floor, that is, the floor on which the passenger has boarded. And using this acquired information and time specific information, the floor where a passenger is expected to get off is specified. For example, when the car 22 moves down, the time determination unit 130 selects a floor below the current floor among the floors stored in the boarding time storage unit 160. On the other hand, when the car 22 moves up, the time determination unit 130 selects a floor above the current floor among the floors stored in the boarding time storage unit 160.

  Further, in the example shown in FIG. 9B, the boarding time storage unit 160 stores the time required for movement for each combination of the floor on which the user has boarded and the floor to get off. However, the boarding time storage unit 160 may store the time required for the difference movement for each difference between the floor on which the boarding is carried and the floor to which the boarding descends (movement for one floor, movement for the second floor,...). .

  Also in the present embodiment, the time specifying information shown in FIG. 9A may be set for each time range as shown in FIG.

  Next, the update process of the boarding time storage unit 160 in the present embodiment will be described. The information acquired by the boarding time updating unit 165 from the control unit 24 of the elevator 20 includes information indicating the floor on which the car 22 of the elevator 20 is stationary. The image analysis unit 120 analyzes the image data generated by the imaging unit 110 while the car 22 is stationary, thereby generating a feature amount of the face of the person who gets on and off the car 22 while the car 22 is stationary. And output to the boarding time updating unit 165. In addition, the boarding time updating unit 165 uses the information acquired from the control unit 24 to identify the floor on which the car 22 is located when the vehicle is stationary. And the boarding time update part 165 specifies the floor which the passenger got on, and the floor which got down for every passenger using these information. For example, when the image analysis unit 120 detects a new face feature amount on a certain floor, it is determined that a person corresponding to this face has come on that floor. On the other hand, when the image analysis unit 120 no longer detects a feature amount of a certain face on a certain floor, it is determined that a person corresponding to this face has descended on that floor. Then, the boarding time update unit 165 updates the boarding time storage unit 160 using the specified floor. For example, the boarding time update unit 165 causes the boarding time storage unit 160 to store the floor on which the passenger has boarded, the floor on which the passenger has boarded, and the boarding date and time as a boarding result in association with the passenger identification information (boarding). Update of the time storage unit 160).

  Moreover, the boarding time update part 165 updates the floor with high possibility that the person gets off, ie, time specific information, using the boarding performance after update. For example, the boarding time updating unit 165 stores one or more of the upper ranks when arranged in the descending order of the number of times of getting off as at least part of the time specifying information.

  As described above, also in the present embodiment, as in the first embodiment, the display device 10 determines the information to be displayed on the display unit 150 by analyzing the image data generated by the imaging unit 110. Therefore, the time from when the passenger gets on the car 22 of the elevator 20 until the information starts to be displayed on the display unit 150 can be shortened.

(Fourth embodiment)
FIG. 10 is a diagram illustrating a functional configuration of the display device 10 according to the fourth embodiment. The display device 10 according to the present embodiment has the same configuration as the display device 10 according to the third embodiment, except for the updating method of the boarding time storage unit 160.

  Specifically, the display device 10 includes an acceleration sensor 168. The boarding time updating unit 165 uses the output from the acceleration sensor 168 instead of acquiring information from the control unit 24. Specifically, the boarding time updating unit 165 first recognizes that the car 22 of the elevator 20 is stationary and the current floor (the floor before the movement). The current floor recognition process is performed using, for example, information acquired from the outside or information manually input by a user of the display device 10 or a maintenance staff.

  Thereafter, when the acceleration sensor 168 detects an upward acceleration, the boarding time updating unit 165 determines that the car 22 has started to move upward. Thereafter, the acceleration sensor 168 detects the downward acceleration, and when the acceleration subsequently becomes zero, it is determined that the car 22 is stationary. Then, the boarding time updating unit 165 identifies the number of floors to which the car 22 has moved using the moving time of the car 22, and uses the number of floors, the moving direction, and the floor before moving to determine the position of the car 22 after moving. (Floor) is specified.

  Conversely, the boarding time updating unit 165 determines that the car 22 has started to move downward when the acceleration sensor 168 detects downward acceleration from the state where the car 22 is stationary. Thereafter, the acceleration sensor 168 detects the upward acceleration, and when the acceleration becomes zero after that, it is determined that the car 22 is stationary. Then, the boarding time updating unit 165 identifies the number of floors to which the car 22 has moved using the moving time of the car 22, and uses the number of floors, the moving direction, and the floor before moving to determine the position of the car 22 after moving. (Floor) is specified.

  By repeating the above processing, the boarding time updating unit 165 can continue to recognize the current position of the car 22.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. Further, unlike the third embodiment, since there is no need to communicate with the control unit 24, the display device 10 can be easily installed in the car 22.

(Fifth embodiment)
The display device 10 according to the present embodiment has the same configuration as that of any of the above-described embodiments except that it is determined whether or not to perform the processing illustrated in FIG. Specifically, the information determination unit 140 determines information to be displayed on the display unit 150 using the time determined by the time determination unit 130 when the current time is included in the first time range. On the other hand, when the current time is included in the second time range different from the first time range, the information determination unit 140 displays the current time on the display unit 150 in a different manner from when included in the first time range. Decide what information you want.

  FIG. 11 is a flowchart illustrating an example of processing performed by the display device 10 in the present embodiment. First, the time determination unit 130 of the display device 10 determines whether or not the current time is within a preset time range (hereinafter referred to as a first time range). When the current time is in the first time range (step S10: Yes), the display device 10 performs the processes shown in steps S20 to S120. On the other hand, when the current time is not within the first time range (step S10: No), that is, when the current time is included in a second time range different from the first time range, it is determined in advance. Information to be displayed on the display unit 150 is determined according to the given schedule (step S12). For example, the information update unit 175 acquires the advertisement display schedule from the information server 30 and stores it in the information storage unit 170.

  In the present embodiment, the first time range is set so as to include, for example, a time when the car 22 is getting on and off abruptly. In this case, the processing shown in steps S20 to S120 is performed at a time when there is little getting on and off the car 22.

(Sixth embodiment)
In the display device 10 according to the present embodiment, when a plurality of passengers have boarded the elevator 20, the time determination unit 130 is the first except that the estimated time is corrected using the number of passengers of the elevator 20. This is the same as the display device 10 according to any one of the first to fifth embodiments.

  When a plurality of passengers have boarded on a certain floor, the time determination unit 130 determines the estimated time for each passenger as shown in FIG. This determination method is as shown in the first embodiment. In the present embodiment, as in the third embodiment, the boarding time storage unit 160 stores a floor on which the person is likely to get off as at least a part of the time specifying information. For this reason, the time determination unit 130 can specify, for each passenger, how many times the elevator 20 stops at another floor before the passenger arrives at the desired floor (hereinafter referred to as a stop floor number). . The greater the number of stops, the longer the passenger will be in the elevator 20. Therefore, the time determination unit 130 corrects the estimated time for each passenger using the stop floor number of the passenger. For example, as shown in FIG. 12B, the time determination unit 130 increases the estimated time as the stop floor number increases. As an example, the time determination unit 130 adds a value obtained by multiplying the stop rank by a constant to the estimated time.

  And the time determination part 130 determines the assumption time which the information determination part 140 should use when selecting the information which should be displayed on the display part 150 using the assumption time after correction | amendment for every passenger. This processing is, for example, as shown in the first embodiment.

  In addition, it is preferable that this process is performed whenever the elevator 20 stops and a person gets on and off. For example, it is assumed that a person gets on the middle floor or a person who has been assumed to have the longest boarding time gets off the middle.

  According to this embodiment, the same effect as that of the first embodiment can be obtained. Further, since the boarding time for each passenger when a plurality of passengers have boarded is corrected using the stop floor number, the estimated time can be calculated with high accuracy. As a result, the information determination unit 140 Information to be provided to the user can be selected with high accuracy.

  As mentioned above, although embodiment and the Example were described with reference to drawings, these are illustrations of this invention and can also employ | adopt various structures other than the above.
