(Embodiment)
The in-vehicle electronic device operating device 10 according to the present exemplary embodiment allows a driver or other operator to move a pointer displayed on the screen using a touch pad installed on the center console, thereby selecting an input operation or the like. I do. In such an operation, it is necessary to set the size of the touch pad to a certain extent so that there is no operation that is too fine for the operator. However, there are cases where a large touchpad cannot be placed on the center console because a cup holder or other equipment is installed. In the present embodiment, as an outline, even if a small touchpad is used, an interface that can be operated comfortably is realized by preventing the operator from overrunning the operation.

  FIG. 1 is a schematic diagram showing an entire in-vehicle electronic device operating device 10 according to the present embodiment. FIG. 2 is a functional block diagram showing a schematic configuration of the in-vehicle electronic device operating device 10 of FIG. The in-vehicle electronic device operating device 10 includes a display unit 11, an input unit 12, a control unit 13, and a storage unit 14. FIG. 3 is a schematic diagram illustrating an example of an image displayed on the display unit 11. FIG. 3A shows an example of a menu screen, and FIG. 3B shows an example of an air conditioner operation screen. FIG. 4 is a diagram schematically showing a cross section when the input unit 12 is viewed from the side surface direction.

  As shown in FIG. 1, the display unit 11 has at least one screen. The display unit 11 may be configured by an arbitrary display device such as a liquid crystal display. When the display unit 11 is configured by a liquid crystal display, for example, the display unit 11 is disposed on an instrument panel. The display device constituting the display unit 11 may be a touch panel display or a display incapable of touch operation. In the following description, it is assumed that the display unit 11 is a display that cannot be touched.

  The in-vehicle electronic device operating device 10 may include a so-called head-up display type device in addition to or instead of the display unit 11. In this case, the head-up display type device has a light emitting unit that generates display information as display light, reflects the generated display light toward an observer such as a driver, and the virtual image through the front windshield. Is displayed. The observer is not limited to the driver and may be a passenger sitting in the passenger seat.

  The display unit 11 displays operation buttons 15 for controlling the in-vehicle electronic device. In-vehicle electronic devices to be controlled include, for example, air conditioning, car navigation, audio, electronic mirrors, and the like. The operation buttons for controlling these in-vehicle electronic devices are, for example, “return”, “forward”, “home”, “decision”, “various menus”, “temperature high / low”, “current location”, “volume” This includes items such as “large / small”, “enlargement / reduction”, “speed fast / slow”, “lane change”, or “distance long / short”. The display unit 11 may display each operation button as a character or an icon.

  FIG. 3A shows an example (menu screen) of a display screen displayed by the display unit 11. The display screen of FIG. 3A includes a plurality of operation buttons (15a to 15g). Hereinafter, these operation buttons are also collectively referred to as operation buttons 15. Although the operation button 15 according to the present embodiment is substantially rectangular, the present invention is not limited to this, and the shape of the operation button 15 may be any shape, for example, a circle or an ellipse. The display unit 11 uses operation buttons 15a for displaying various applications, operation buttons 15b for using a telephone, operation buttons 15c for controlling an air conditioner, operation buttons 15d for using car navigation, and audio. An operation button 15e is displayed. Similarly, the display unit 11 displays an operation button 15f for returning to the home screen, and an operation button 15g for returning to the previous screen.

  FIG. 3B shows another example of the display screen (air conditioner operation screen). The display screen of FIG. 3B also includes a plurality of operation buttons (15h to 15q). The display unit 11 includes an operation button 15h for increasing the air volume of the air conditioner, an operation button 15i for decreasing the air volume, an operation button 15j for switching the air conditioner mode, and an operation button 15k for increasing the set temperature of the air conditioner. An operation button 15l for reducing the set temperature, an operation button 15m for switching to the auto mode, an operation button 15n for switching the inside air circulation, an operation button 15o for using the defroster, and a defroster for the rear window. And an operation button 15q for switching the use of the compressor.

  The input unit 12 is arranged on the center console as shown in FIG. The input unit 12 includes a touch pad 121 and a tact switch 122 as shown in FIG. As shown in FIG. 4, the operator places his / her arm and wrist on the armrest and palmrest, and touches the touchpad 121 with, for example, a finger.

  The touch pad 121 detects contact by a contact object such as an operator's hand or a stylus pen at a corresponding contact position (input position). In particular, the touch pad 121 detects contact with a part of the operator's hand, for example, a finger at a corresponding input position. The operator manipulates information displayed on each screen constituting the display unit 11 by performing a touch operation on the touch pad 121 of the input unit 12. The touch pad 121 is formed of, for example, transparent glass, and a touch sensor configured by an arbitrary method such as a resistive film method, a capacitance method, a surface acoustic wave method, an infrared method, or an electromagnetic induction method can be used. . In the following description, it is assumed that the touch pad 121 is a capacitive touch pad. The size of the touch pad 121 is preferably 4 inches. By reducing the size of the touch pad 121, a cup holder, another device, or the like can be disposed on the center console.

  As shown in FIG. 4, the tact switch 122 is disposed immediately below the touch pad 121 and supported by the substrate. When the touch pad 121 is displaced downward by the operator's pressing, the tact switch 122 is turned on by the pressing. The tact switch 122 is turned off when the push of the operator is released and the touch pad 121 returns to the original position. When the operator depresses the touch pad 121, the tact switch 122 is turned on to obtain a click feeling.

  In FIG. 4, one tact switch 122 is arranged at the central portion immediately below the touch pad 121. However, the tact switch 122 is not limited to this, and any number can be used as long as the pressure from the touch pad 121 can be detected. It may be arranged at any place. For example, one tact switch 122 may be disposed on the outer periphery of the tact switch 122 immediately below the touch pad 121, or a plurality of tact switches 122 may be disposed at dispersed positions. For example, by arranging a plurality of tact switches 122 directly below the touch pad 121, the input unit 12 may be configured to detect a pressure from the touch pad 121 for each predetermined area of the touch pad 121. Good. That is, the input unit 12 may be configured to detect at which position on the touch pad 121 the operator has pressed when a plurality of fingers of the operator are in contact with the touch pad 121 at the same time. Good.

  The configuration unit arranged immediately below the touch pad 121 is not limited to the tact switch 122, and may be any configuration as long as the pressing from the touch pad 121 can be detected. For example, instead of the tact switch 122, a pressure sensitive sensor such as a piezoelectric element may be disposed immediately below the touch pad 121.

  In addition to the touch pad 121 and the tact switch 122, the input unit 12 may include a filter in order to remove an unnecessary detection signal of the touch pad 121 due to vibration during traveling of the vehicle.

  The control unit 13 is a processor that controls and manages the entire in-vehicle electronic device operating device 10 including each functional block of the in-vehicle electronic device operating device 10. The control unit 13 includes a processor such as a CPU (Central Processing Unit) that executes a program that defines a control procedure, and the program is stored in the storage unit 14, for example.

  The control unit 13 acquires contact information detected on the touch pad 121 from the input unit 12 as an input signal. Specifically, the control unit 13 acquires detection information related to a contact object, for example, contact with an operator's finger and a corresponding input position. The control unit 13 identifies accurate position coordinates on the touch pad 121 where the touch operation is performed based on the detection information regarding the corresponding input position.

  The control unit 13 acquires a signal related to the on state or the off state of the tact switch 122 from the input unit 12. Specifically, when the operator depresses the tact switch 122 via the touch pad 121, the control unit 13 acquires an on-state signal. When the operator stops pressing the touch pad 121 and releases the pressing of the tact switch 122, the control unit 13 acquires a signal in an off state. The control unit 13 identifies the on state or the off state of the tact switch 122 based on the acquired signal.

  The memory | storage part 14 can be comprised with a semiconductor memory, a magnetic memory, etc., and memorize | stores the various information mentioned above, the program for operating the vehicle electronic device operating device 10, etc. The storage unit 14 also functions as a work memory.

  FIG. 5 is a schematic diagram illustrating an example of a correspondence relationship between a predetermined area of the input unit 12 and an operation area on the screen configuring the display unit 11. FIG. 5A shows a predetermined region R1 of the input unit 12 (touch pad 121). FIG. 5B shows an operation area R <b> 2 on the screen constituting the display unit 11.

  The control unit 13 sets a predetermined region R1 of the input unit 12 and an operation region R2 on the screen constituting the display unit 11. The predetermined region R1 of the input unit 12 is a region for performing a touch operation with a part of the operator's hand. The back side in FIG. 5A is an area on the touch pad 121 farthest from the wrist when the operator's arm and wrist are placed on the armrest and palmrest, respectively. The near side is the opposite side of the back side.

Here, each coordinate of the region R1 corresponds to each coordinate of the region R2 on a one-to-one basis. For example, the coordinates (x _i , y _i ) of the region R1 in FIG. 5A correspond to the corresponding coordinates (x _j , y _j ) of the region R2 in FIG. 5B. When the lower left of the region R1 in FIG. 5A is the origin related to the region R1, and the lower left of the region R2 in FIG. 5B is the origin related to the region R2, (x _i , y _i ) of the region R2 The following relationship holds between (x _j , y _j ).
x _j = α × x _i ........................... (1)
y _j = β × y _i (2)
Α and β in the formulas (1) and (2) are values larger than 1. When the aspect ratios of the region R1 and the region R2 are the same, α = β. When the aspect ratio of the region R2 of the region R1 is different, α and β are set as appropriate according to the aspect ratio.

The coordinates (x _j, y _j) on the screen in order to operate (selection, etc.) the operation button 15 located on the coordinates (x _i, y _i) of the region R1 may be a touch operation. Thus, in this embodiment, touch input based on absolute coordinates is employed.

  Here, in the case of touch input using absolute coordinates, the smaller the size of the touch pad 121, the quicker the operation pointer 16 moves due to the operation on the touch pad 121, and hunting or overshooting of the operation is likely to occur. . In particular, when the touch pad 121 is 4 inches, these problems are likely to appear remarkably as compared to a size of the touch pad 121 of 5 inches or more. Therefore, in the present embodiment, the occurrence of these problems is suppressed by optimizing the display method of the operation pointer 16. Hereinafter, the display method of the operation pointer 16 will be described in detail.

When the input unit 12 detects an input by the operator's hand, the display unit 11 displays the operation pointer 16 at a display position corresponding to the input position based on the control of the control unit 13. That is, if the input position is the coordinates (x _i , y _i ) of the area R1, the operation pointer 16 is displayed at the display position of the coordinates (x _j , y _j ) of the area R2. FIGS. 6A and 6B are diagrams showing examples in which the operation pointer 16 is displayed on the display screens shown in FIGS. 3A and 3B, respectively. As shown in FIG. 6A, the operation pointer 16 has a certain degree around a display position (for example, coordinates (x _j , y _j )) corresponding to an input position (for example, coordinates (x _i , y _i )). It is a circle of the size (predetermined radius). The display unit 11 displays the operation pointer 16 in a spotlight shape. That is, the display part 11 displays the part which overlaps with the operation pointer 16 among the operation buttons 15 so that visual recognition is possible. In FIG. 6A, a part of the operation button 15 c and a part of the operation button 15 d overlap the operation pointer 16. However, the overlapped portion is displayed so as to be visible. As described above, the display unit 11 displays the overlapping portion of the operation button 15 and the operation pointer 16 so that the operation button 15 can be determined instead of being hidden by the operation pointer 16.

  The inside of the operation pointer 16, that is, the inside of the circular area is set so that at least one of display color and luminance is different from the outside of the area. Specifically, for example, the color inside the operation pointer 16 is set to yellow or the like. Alternatively, for example, the brightness inside the operation pointer 16 is increased. Thus, the recognition speed inside the operation pointer 16 can be increased by making the display mode inside the operation pointer 16 different and raising the position of the operation pointer 16. This is due to the same effect as the effect that the visual field space range is specified by applying a spotlight to the object (also referred to as a visual frame effect). Thus, according to the operation pointer 16 in this embodiment, the operation button 15 to be selected, that is, the target operation button can be easily grasped. In the above description, the color or the like inside the operation pointer 16 is changed. However, the present invention is not limited to this, and the color or the like of the area outside the operation pointer 16 may be changed. Specifically, for example, the color outside the operation pointer 16 is set to gray. Alternatively, the brightness outside the operation pointer 16 may be lowered.

Further, the display unit 11 highlights the operation button 15 corresponding to the input position. Specifically, when the input position is the coordinates (x _i , y _i ) of the region R1, the control unit 13 displays, on the display unit 11, the operation button 15 positioned at the coordinates (x _j , y _j ) of the region R2. Highlight it. That is, the display unit 11 highlights the operation button 15 where the center of the operation pointer 16 exists. Thereby, the operation button 15 in the selected state can be easily grasped. In FIG. 6A and FIG. 6B, the operation button 15d and the operation button 15i are highlighted. When the control unit 13 acquires a signal indicating that the tact switch 122 is turned on in the highlighted state, the control unit 13 determines the selection of the operation button 15. That is, if the selection of the operation button 15d is confirmed in FIG. 6A, the car navigation function screen is displayed and the car navigation can be used. If the selection of the operation button 15i is confirmed in FIG. 6B, the air volume of the air conditioner is reduced to a certain extent.

The size of the operation pointer 16 will be described in detail with reference to FIG. As shown in FIG. 7A, at least some of the operation buttons 15 (operation buttons 15a to 15e in FIG. 7A) are aligned in a predetermined direction (here, the horizontal direction). . In FIG. 7A, the interval between the arranged operation buttons 15 (hereinafter referred to as the alignment pitch) is L1. Here, the alignment pitch is the distance between the farthest ends of the adjacent operation buttons 15 among the plurality of operation buttons 15 to be aligned. That is, for example, the distance between the left side of the operation button 15c and the right side of the operation button 15d corresponds to the alignment pitch. In FIG. 7A, there is a gap between the operation buttons 15 to be aligned. Therefore, the alignment pitch L1 is expressed as follows.
L1 = L3 × 2 + d ... Formula (3)
In Expression (3), L3 is the width (horizontal width) of the operation buttons 15 in the alignment direction, and d is the width of the gap between the operation buttons 15. Note that L1 is equal to twice the size (width in the selection direction of the operation button 15) in the selection direction (here, the horizontal direction) when the operator performs a selection operation.

  When there is no gap between the operation buttons 15 (when d = 0), the alignment pitch L1 is equal to twice the width (horizontal width) of the operation buttons 15 in the alignment direction. In FIG. 7B, since there is no gap between the operation buttons 15, the alignment pitch L <b> 1 is twice the width of the operation buttons 15. In FIG. 7B, the operation buttons 15 (character buttons) are arranged in the vertical direction and the horizontal direction. Preferably, in this case, the alignment pitch is determined based on a shorter width (here, the lateral width).

  As shown in FIG. 7, the present embodiment is characterized in that the width L2 of the operation pointer 16 is equal to or larger than the alignment pitch L1. Here, the width L2 of the operation pointer 16 is the width of the operation pointer 16 in a predetermined direction. The predetermined direction is the same as the predetermined direction in which the operation buttons 15 are aligned, and is a horizontal width here. The width is a width at a position including the center of the operation pointer 16. When the operation pointer 16 is circular, the width of the operation pointer 16 is equal to the diameter. Thus, since the width L2 of the operation pointer 16 is equal to or greater than the alignment pitch L1, the size (width) of the operation pointer 16 is a size that can include the adjacent operation buttons 15.

  FIG. 8 is a diagram showing the relationship between the size of the operation pointer 16 and the ease of selection operation. FIG. 8A shows a comparative example. The width (diameter) of the operation pointer 16 of the comparative example is smaller than that of the operation button 15. When the operation button 15y is selected with the operation pointer 16 having the size shown in FIG. 8A, the operator is conscious of trying to align the operation pointer 16 with the center of the operation button 15y. Therefore, a fine operation must be performed, and the operation button 15 and the operation pointer 16 are watched.

  On the other hand, FIG. 8B shows a case where the operation button 15y is selected by the operation pointer 16 of the present embodiment. In this case, if the center 160 of the operation pointer 16 is included in the area of the operation button 15y, the operation button 15y is selected. Since the size of the operation pointer 16 is larger than the alignment pitch, it is difficult to be aware of trying to align the center of the operation pointer 16 with the center of the operation button 15y. This eliminates the need for fine operations. Further, since the size of the operation pointer 16 is relatively large, the movement is felt slower than the operation pointer having a small size as in the comparative example, and the movement becomes easy to visually recognize. Therefore, for example, when the operation pointer 16 is moved by performing a slide operation, the operation pointer 16 can be easily moved to the target position.

  In the above, the lower limit of the size of the operation pointer 16 is shown. On the other hand, the upper limit of the size of the operation pointer 16 is determined based on the number of operation buttons 15 included in the circular area of the operation pointer 16. Preferably, the number of operation buttons 15 is 10 or less. In the example shown in FIG. 7A, the number of operation buttons 15 included in the operation pointer 16 is 2, and the size is set to 3 at the maximum even if the operation pointer 16 is moved to another location. Yes. In the example shown in FIG. 7B, the number of operation pointers 15 included in the operation pointer 16 is ten. Since the number of the operation buttons 15 that can be visually recognized by the operator in a short time (for example, within 2 seconds) is 10 or less, the size of the operation pointer 16 is limited in this way, so that the target operation buttons can be displayed in a short time. Can be easily grasped.

  Next, the operation of the vehicle electronic device operating device according to the embodiment of the present invention will be described with reference to the flowchart shown in FIG.

  First, the display unit 11 displays the operation buttons 15 for controlling the in-vehicle electronic device (step S10).

  Next, the control part 13 determines whether the input part 12 detected the input by the operator's hand (step S20). If no input is detected, step S20 is repeated. When the input is detected, the control unit 13 acquires the contact information detected on the touch pad 121 from the input unit 12 as an input signal. Specifically, the control unit 13 identifies an accurate position coordinate on the touch pad 121 where the touch operation is performed based on detection information regarding the input position, and the display unit 11 operates the display position according to the input position. The pointer 16 is displayed (step S30). As described above, the width of the operation pointer 16 displayed on the display unit 11 is equal to or larger than the alignment pitch of the aligned operation buttons 15.

Furthermore, the control part 13 highlights the operation button 15 according to an input position by the display part 11 (step S40). Specifically, when the input position is a predetermined coordinate (x _i , y _i ), the control unit 13 emphasizes the operation button 15 positioned at the coordinate (x _j , y _j ) of the region R2 on the display unit 11. Display. When there is no operation button 15 to be highlighted at the input position, the control unit 13 does not highlight any operation button 15.

  Subsequently, the control unit 13 determines whether or not the tact switch 122 is on (step S50). If the tact switch 122 is not on, the process returns to step S20. On the other hand, when the tact switch 122 is on, the control unit 13 determines the selection of the operation button 15 (step S60) and ends the process.

  As described above, according to the in-vehicle electronic device operating device 10 according to the present embodiment, since the width of the operation pointer 16 is equal to or larger than the alignment pitch of the operation buttons 15, the movement of the operation pointer 16 can be felt slowly. In addition, this makes it possible to prevent hunting and overshooting of operations, so that a plurality of aligned operation buttons can be selected more easily.

  In this embodiment, the example in which the width of the operation pointer is equal to or larger than the alignment pitch has been described, but the present invention is not limited to this. For example, as in the example shown in FIG. 10A, the width L2 of the operation pointer 16 may be larger than the width L3 of the predetermined operation button 15 (the operation button 15d in this case). When there are a plurality of operation buttons 15 having different sizes on the display screen, the width of any one of the operation buttons 15 may be used as a reference. For example, the width of the operation button 15f (horizontal or vertical width in FIG. Any of these may be used as a reference. As described above, the movement of the operation pointer 16 can be made to feel slow by making the width of the operation pointer 16 larger than the width of the predetermined operation button 15. Further, operation hunting and overshoot can be prevented.

  Further, as in the example shown in FIG. 10B, the width L2 of the operation pointer 16 is larger than a predetermined operation button 15 (here, the operation button 15d), and at least two of the plurality of arranged operation buttons 15 are operated. The size may overlap with the button 15 (in this case, the operation buttons 15c and 15d). In this manner, the movement of the operation pointer 16 can be made to feel slow by making the size of the operation pointer 16 overlap the two operation buttons 15. In addition, hunting and overshooting of operations can be prevented.

  In addition, the in-vehicle electronic device operating device 10 according to the present embodiment employs touch input based on absolute coordinates. According to the in-vehicle electronic device operating device 10 according to the present embodiment, even if the touch pad 121 is downsized, the operability can be prevented from being impaired, and the small touch pad 121 can be comfortably touched by absolute coordinates. Input can be made. In particular, with touch input using absolute coordinates, it is not necessary to slide the operation pointer 16 to the operation position, and it is possible to quickly operate the operation buttons 15 existing at positions farther than touch input using relative coordinates. Further, since it is not necessary to perform a sliding operation on the touch pad 121, it is not necessary to consider the friction of the touch pad 121. Particularly in summer, when the interior of the vehicle gets hot and the fingers sweat, it may be difficult to slide the finger on the touchpad. If the touch input is based on absolute coordinates, it is not necessary to perform a slide operation, so that it can be operated comfortably.

  As described above, in this embodiment, it is preferable to employ touch input based on absolute coordinates, but touch input based on relative coordinates may be employed, and in this case, the present invention can be applied. . In the case of touch input using relative coordinates, a slide operation is performed on the touch pad, and the operation position on the screen is determined based on the amount and speed of the slide operation.

  In this embodiment, an example in which the operation pointer 16 is circular has been described. However, the present invention is not limited to this, and the operation pointer 16 may be substantially circular (for example, an ellipse). When the operation pointer 16 is oval, the width of the operation pointer 16 is the length of the long axis or the length of the short axis.

  Alternatively, the shape of the operation pointer 16 is not limited to a substantially circular shape, and may be a substantially rectangular shape or a polygonal shape (for example, a triangle). For example, when the operation pointer 16 is a triangle, the width of the operation pointer 16 may be any one of the three sides. Or the average value of the length of three sides may be sufficient. Alternatively, the height of the triangle may be the width of the operation pointer 16. Preferably, the shape of the operation pointer 16 is line symmetric or point symmetric. By making the shape of the operation pointer 16 line-symmetric or point-symmetric, the consciousness of aligning the center of the operation pointer 16 with the center of the operation button 15 can be made less effective and the operability can be improved.

  Note that the display unit 11 may display the boundary line of the operation pointer 16 in a blurred manner. Thus, by displaying the boundary line of the operation pointer 16 in a blurred manner, the consciousness of aligning the center of the operation pointer 16 with the center of the operation button is more difficult to work, and the operability can be further improved.

  The display unit 11 may display the inside of the substantially circular area of the operation pointer 16 offset from the front or the depth direction compared to the outside of the area. By doing so, the inside of the region of the operation pointer 16 is offset and displayed, so that the target operation button 15 can be easily grasped. Note that the display unit 11 may perform only offset display without changing the display color and brightness inside the region of the operation pointer 16 from the outside. In this way, it is possible to easily grasp the target operation button 15 without changing the visibility between the inside and outside of the area of the operation pointer 16.

  The display unit 11 according to the present embodiment displays the operation pointer 16 with a constant size on a certain display screen. When the display screen is switched to another display screen, the display unit 11 may change the size of the operation pointer 16. That is, the display unit 11 may change the size of the operation pointer 16 at the time of transition of the display screen (at the time of switching) according to the layout of the display screen. Specifically, the display unit 11 displays another display screen in which at least one of the size and arrangement of the operation buttons 15 is different, and changes the size of the operation pointer 16 when displaying another display screen. To do. For example, the display unit 11 may change the size of the operation pointer 16 on the display screen shown in FIGS. 6A, 6B, and 7B according to the layout of the screen. By doing so, the operability can be improved even when another display screen in which at least one of the size and arrangement of the operation buttons is different is displayed.

  In the present embodiment, when there is one input position (when there is a so-called single touch input), the operation pointer 16 shown in FIG. 6 is displayed. However, multi-touch reception is also possible. When the input unit 12 detects a multi-touch input, the operation pointer 16 may not be displayed. Alternatively, the operation pointer 16 may be displayed with a smaller size. In this case, the control unit 13 performs various operations based on the multi-touch operation (for example, an enlargement operation if a pinch operation or the like). By doing so, the operability can be improved without unnecessarily displaying the operation pointer 16 during the multi-touch operation.

  In the present embodiment, the selection of the operation button 15 is confirmed when the tact switch 122 is on, but the present invention is not limited to this. For example, the tact switch 122 may not be provided, and the selection of the operation button 15 may be confirmed by a tap operation on the operation button 15. Alternatively, the selection of the operation button 15 may be confirmed when the touched finger or the like is separated in a state where the operation button 15 is highlighted.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various modifications and corrections based on the present disclosure. Therefore, it should be noted that these variations and modifications are included in the scope of the present invention. For example, the functions included in each means, each step, etc. can be rearranged so that there is no logical contradiction, and a plurality of means, steps, etc. can be combined or divided into one. .
