In an input system using such an input device, there is a problem in that, simultaneously with the operation using the input device, other operations performed by touching the input surface are limited. For example, in an input system in which a touch panel in which the number of contact points that can be detected at the same time is three and an input device provided with three conductors are combined, another touch is performed while an operation using the input device is performed. The location cannot be detected. Therefore, another operation cannot be performed at the same time as the operation using the input device. In addition, it is difficult to realize an input device having a small-diameter shape such as a knob because the three conductors must be provided at intervals that can be clearly identified.

A main body having a surface, a first conductor portion provided on the first surface, and a second conductor portion provided on the second surface. The first conductor portion and the second conductor portion are electrically connected to each other, and the first conductor portion has a first surface in the in-plane direction of the first surface when viewed from a direction perpendicular to the first surface. It is characterized in that it has a directivity capable of specifying the direction of the first conductor portion.

  Hereinafter, an input device, an input device, and an input system according to an embodiment of the present invention will be described in detail with reference to the drawings. The present invention is not limited to this embodiment.

Embodiment 1.
1 is a perspective view of an input system according to a first embodiment of the present invention. The input system 1 includes an input device 200 and an input device. The touch panel 100 shown in FIG. 1 is a detection device and constitutes a part of the input device. The detailed configuration of the input device will be described later. A user of the input system 1 brings the input device 200 into contact with the input surface 100a of the touch panel 100 to perform an input operation of information via the touch panel 100. In the input system 1, various display objects are displayed on the display unit on which the touch panel 100 is overlapped according to the position and type of the input device 200 that is in contact with the input surface 100a. The display unit will be described later. In the input system 1, various displayed display objects are changed according to the change in the orientation of the input device 200 that is brought into contact with the input surface 100a.

  First, the input device 200 will be described. FIG. 2 is a perspective view of the input device according to the first embodiment. FIG. 3 is a side view of the input device according to the first embodiment. FIG. 4 is a plan view of the input device according to the first embodiment. FIG. 5 is a bottom view of the input device according to the first embodiment.

  The input device 200 includes a main body 2 formed of an insulating material. The main body 2 has a bottom surface 2a that is a first surface. The bottom surface 2a is a flat surface. As shown in FIG. 5, in the first embodiment, the bottom surface 2a has a circular shape when viewed from the direction perpendicular to the bottom surface 2a. In the input operation using the input device 200, the bottom surface 2a contacts the input surface 100a of the touch panel 100.

  The main body 2 has a gripping surface 2b that is a second surface. In the first embodiment, the grip surface 2b is a cylindrical surface. When the bottom surface 2a is in contact with the input surface 100a of the touch panel 100, the grip surface 2b does not contact the input surface 100a of the touch panel 100. The grip surface 2b is a portion that a user who operates the input device 200 grips by hand.

  A first conductor portion 3 made of a conductor is provided on a part of the bottom surface 2a of the main body 2. As shown in FIG. 5, the first conductor portion 3 is provided so as to contact the outer peripheral edge of the bottom surface 2a. The first conductor portion 3 has a shape having directivity capable of specifying the in-plane orientation of the bottom surface 2a when viewed from the direction perpendicular to the bottom surface 2a. For example, a shape that is not rotationally symmetrical is a shape that has directivity. The state in which the first conductor portion 4 is oriented is the initial state. When the first conductor 3 is rotated from the initial state within the plane of the bottom surface 2a and the first conductor 3 is not rotationally symmetrical, the first conductor 3 is not rotated until it returns to the initial state. The state does not overlap with the state. Therefore, if the first conductor portion 3 has a shape that is not rotationally symmetric, it is possible to specify the direction. For example, if the first conductor portion 3 is a rotationally symmetric square, the orientation cannot be specified because the first conductor portion 3 overlaps with the initial state every 90 ° rotation in the plane of the bottom surface 2a. As shown in FIG. 5, the first conductor portion 3 has a directional shape by forming a pentagonal shape that is not rotationally symmetric. Since the first conductor portion 3 has a directional shape, if the positional relationship between the first conductor portion 3 and the input device 200 is known, the position and orientation of the first conductor portion 3 will change. The position and orientation of the input device 200 can be grasped.

  By associating the shape and size of the first conductor portion 3 with the type of the input device 200, if the shape and size of the first conductor portion 3 are grasped, the type of the input device 200 is grasped. It becomes possible.

  A second conductor portion 4 formed of a conductor is provided on the grip surface 2b of the main body 2. The second conductor portion 4 is provided over the entire circumference of the grip surface 2b, which is a cylindrical surface, in the circumferential direction. Since the second conductor portion 4 is provided over the entire circumference of the gripping surface 2b in the circumferential direction, when the user grips the gripping surface 2b, the second conductor portion 4 does not contact the user. It is easy for your hands to come into contact.

  The main body 2 is provided with a connection conductor portion 5 which is formed of a conductor and electrically connects the first conductor portion 3 and the second conductor portion 4 to each other. Since the first conductor portion 3 and the second conductor portion 4 are electrically connected, when the hand of the user who holds the holding surface 2b contacts the second conductor portion 4, the first conductor portion 3 3 becomes the same potential as the human body of the user. The connecting conductor portion 5 is not limited to being provided on the surface of the main body 2. The connection conductor portion 5 may be provided inside the main body 2 as long as the first conductor portion 3 and the second conductor portion 4 are electrically connected. Further, in the following description, the first conductor portion 3 is in contact with the input surface 100a means that the gripping surface 2b is gripped by the user and has the same potential as the human body of the user. Touches the input surface 100a.

  Next, the touch panel 100 will be described. As shown in FIG. 1, the touch panel 100 has an input surface 100a. When the human body or the conductor comes into contact with the input surface 100a, the touch panel 100 grasps the position where the human body or the conductor comes into contact based on the change in capacitance.

  The input surface 100a is a surface that covers a display unit described later. The display unit displays an image such as a display object. Various display objects displayed on the display unit are visible through the input surface 100a. The touch panel 100 accepts various input operations by touching the display object displayed on the display unit and the input surface 100a. For example, when it is detected that the user's finger touches the area of the input surface 100a that overlaps the area where the number is displayed, it is determined that the input operation for selecting the number is performed. In the following description, making the display displayed on the display unit visible through the touch panel 100 is also referred to as simply displaying on the touch panel 100.

  Next, the input device will be described. FIG. 6 is a diagram illustrating a functional configuration of the input-target device according to the first embodiment. The input device 110 includes a detection device 101 and an information processing device 102. The detection device 101 is the touch panel 100.

  The detection device 101 outputs, to the information processing device 102, contact information indicating that a human body or a conductor has contacted the input surface 100a based on the change in capacitance. FIG. 7 is a diagram schematically showing the input surface of the detection device according to the first embodiment. FIG. 7 shows a state in which the contact of the first conductor portion 3 is detected. One square of the grid shown in FIG. 7 is the minimum unit capable of detecting the contact of the conductor due to the change of the electrostatic capacitance. The contact information output by the detection device 101 is information indicating the position of the square where the capacitance has changed. The information indicating the position of the square where the electrostatic capacitance has changed is, for example, coordinate information.

  The data storage unit 14 includes a shape holding unit 121 and a setting holding unit 122. The data storage unit 14 holds information for identifying the input device 200 that is in contact with the input surface 100a of the touch panel 100 and determining the display object to be displayed on the display unit 16.

  The shape holding portion 121 holds information indicating the shapes of the plurality of first conductor portions 3 different from each other. FIG. 8 is a diagram showing an example of another shape of the first conductor portion in the first embodiment. The shape shown in FIG. 8 has the same number of corners as the pentagonal first conductor portion 3 illustrated in FIG. 5, but the shape is different. The pentagonal shape shown in FIG. 5 and the like is the shape of pattern 1, and the shape shown in FIG. 8 is the shape of pattern 2.

  The setting holding unit 122 holds information for identifying the input device 200 from the shape of the first conductor portion 3. FIG. 9 is a diagram showing information stored in the setting storage unit according to the first embodiment. Details of the information stored in the setting storage unit 122 will be described later.

  The detection device connection interface 11 is an interface to which the detection device 101 is connected. The contact information output from the detection device 101 is input to the data processing unit 13 through the detection device connection interface 11.

  The data processing unit 13 includes a detection area generation unit 130, a feature point extraction unit 131, a shape determination unit 132, and a size calculation unit 133. The detection area generation unit 130 determines the area in which the human body or the conductor is in contact with the detection device 101, based on the information input to the data processing unit 13.

  The detection area generation unit 130 generates the detection area 21, which is the area in contact with the input surface 100a, from the information indicating the position of the mass where the electrostatic capacitance has changed, which is the contact information. The detection area generation unit 130 functions as a conductor detection unit that detects that the first conductor unit 3 is in contact with the input surface 100a. The detection area generation unit 130 determines the area in which the mass whose change in capacitance exceeds the threshold value is in contact, and generates the detection area 21. When the first conductor portion 3 comes into contact with the input surface 100a, the shape of the detection region 21, which is an aggregate of masses whose capacitance has changed, also changes to a pentagon, which is the shape of the first conductor portion 3. The shape will be close.

  The feature point extraction unit 131 extracts a corner that is a feature point from the shape of the detection area 21. FIG. 10 is a diagram showing a detection example of feature points in a state where the contact of the first conductor portion shown in FIG. 7 is detected. As shown in FIG. 10, five feature points A to E are extracted from the detection area 21 generated by the contact of the pentagonal first conductor portion 3. The five feature points A to E are extracted as coordinate information.

  The shape determination unit 132 determines from the coordinate information of the extracted feature points A to E whether the shape of the detection region 21 approximates any one of the plurality of shapes stored in the data storage unit 14. If the shape determination unit 132 determines that the shape of the detection region 21 does not approximate any one of the plurality of shapes held in the data storage unit 14 or if the feature points are not extracted, the detection device It is determined that the user's finger is in contact with 101. As shown in FIG. 10, if the shape connecting the characteristic points A to E with a line is a pentagonal shape, and the information on the pentagonal shape is also stored in the data storage unit, the shape determination unit 132 causes the shape determination unit 132 to detect the detection area 21. Is approximated to the shape held in the storage unit.

  When it is determined that the shape of the detection area 21 is similar to the shape held in the storage unit, the dimension calculation unit 133 determines the length a, which is the distance between the characteristic point A and the characteristic point B, as the characteristic point A. It is calculated using the coordinates of and the coordinates of the characteristic point B. The length a is the length of the first conductor portion 3 along the outer periphery of the bottom surface 2a of the input device 200. The dimension calculation unit 133 calculates the normal direction indicated by the arrow G in FIG. In the shape of the detection area 21 shown in FIG. 10, the normal direction G is the characteristic point from the intersection F of the line connecting the characteristic points A and C and the line connecting the characteristic points B and E. It is defined in the direction towards D.

  Here, the information stored in the setting storage unit 122 illustrated in FIG. 9 will be described. In the information stored in the setting storage unit 122, the type of the input device 200, the shape of the first conductor portion 3, the length a, the length b, and the type of display object are associated with each other.

  The type of the input device 200 is held as information such as No1 and No2. The shape of the first conductor portion 3 is held by information such as pattern 1 and pattern 2.

  FIG. 11 is a diagram illustrating the center of gravity of the bottom surface of the input device according to the first embodiment. The length b is information indicating the center of gravity position O of the bottom surface 2a of the input device 200. In the shape of the pattern 1 shown in FIG. 10, the length b from the intersection F of the line connecting the characteristic points A and C and the line connecting the characteristic points B and E toward the characteristic point D. The point separated by just the point is the center of gravity O of the bottom surface 2a.

  The type of display object indicates the type of display object displayed when the input device 200 is brought into contact with the input surface 100a. FIG. 12 is a diagram showing a display example on the touch panel in the input system according to the first embodiment. In FIG. 12, an arc-shaped bar graph is displayed around the input device 200. The arc-shaped bar graph becomes the display object of the pattern V shown in FIG. In the display object of the pattern V, the color and the like are different between the one end side and the other end side of the bar graph. In FIG. 12, the difference in color and the like is represented by the presence or absence of hatching.

  FIG. 13 is a diagram showing another display example on the touch panel in the input system according to the first embodiment. In FIG. 13, an arc-shaped bar graph is displayed around the input device 200, and A, B, C, D, and E are displayed from one end side to the other end side of the bar graph. The arc-shaped bar graph on which A, B, C, D, and E are displayed becomes the display object of the pattern W shown in FIG. Further, outside the arc-shaped bar graph in which A, B, C, D, and E are displayed, a pointer indicating which area of A, B, C, D, and E is selected is displayed. ing.

  FIG. 14 is a diagram showing still another display example on the touch panel in the input system according to the first embodiment. In FIG. 14, a plurality of buttons are displayed on the side of the input device 200. A, B, C, and D are displayed on each of the buttons. The buttons on which A, B, C, and D are displayed become the display objects of the pattern X shown in FIG. Further, the buttons displayed as A, B, C, and D can be changed in color and the like from the other buttons to determine which button is selected. In FIG. 14, the difference in color and the like is represented by the presence or absence of hatching, and the button with B is selected.

  The data processing unit 13 directs the information indicating the position of the intersection F, the information indicating the length a, the information indicating the length b, the information indicating the normal direction, and the information indicating the position of the center of gravity O to the display generating unit 15. Output.

  The display generation unit 15 causes the display unit 16 to display the display object based on the information output from the data processing unit 13. For example, as shown in FIG. The process when the first input device 200 contacts the input surface 100a will be described. The data processing unit 13 outputs "10" as information indicating the length a. The data processing unit 13 outputs “20” as information indicating the length b.

  The input device 200 in which the length a is “10” and the length b is “20” is No. 1 is an input device. The display generation unit 15 causes the display unit 16 to display the pattern V display object. Specifically, the bar graph shown in FIG. 12 is displayed on touch panel 100.

  The display generation unit 15 grasps the position of the input device 200 based on the information indicating the position of the center of gravity O output from the data processing unit 13, and determines the position where the bar graph is displayed. The display generation unit 15 detects the orientation of the input device 200 by using the information indicating the normal direction output from the data processing unit 13, and the size of the area of the bar graph having a different color depending on the orientation. To decide. The display generation unit 15 causes the touch panel 100 to display a bar graph having different colors depending on the size of the determined area. The display generation unit 15 also functions as an orientation determination unit that determines the orientation of the first conductor portion 3. By rotating the input device 200 in the direction indicated by the arrow P in FIG. 12, the orientation of the input device 200 changes.

  When the orientation of the input device 200 changes and the position of the detection area 21 changes, the data processing unit 13 recalculates the information indicating the normal direction and the information indicating the position of the center of gravity O, and causes the display generation unit 15 to calculate the information. To output.

To display on the display unit 16. For example, by associating the sizes of regions of different colors in the bar graph with numerical values, it becomes possible to input a numerical value corresponding to the rotation of the input device 200 to an external device through the input system 1. For example, when the input system 1 is provided in a processing device that is an external device, the rotation of the input device 200 can be performed by associating the size of the regions of different colors in the bar graph with the numerical value indicating the processing speed of the processing device. It is possible to change the processing speed by increasing or decreasing the numerical value. That is, the user can operate the input device 200 like a dial that changes an input value by a rotating operation.

  No. When the second input device 200 is brought into contact with the input surface 100a, a bar graph on which the display objects A, B, C, D, and E of the pattern W are displayed is displayed. The position of the display object indicating which of the areas A, B, C, D, and E is selected is changed according to the change in the orientation of the input device 200.

  No. When the input device 200 of No. 3 is brought into contact with the input surface 100a, the buttons displaying A, B, C, and D, which are the patterns X, are displayed. Depending on the change in orientation of the input device 200, different colored buttons can be changed to indicate which button is selected.

  FIG. 15 is a flowchart showing a procedure of displaying a display object on the touch panel using the input device in the input system according to the first embodiment. The detection device 101 monitors whether or not the capacitance has changed. When a change in capacitance is detected (step S1), coordinate information indicating the detection area 21 where the capacitance has changed on the input surface 100a is output to the data processing unit 13 (step S2). Next, extraction of the characteristic points of the detection area 21 and determination of whether the shape of the detection area 21 approximates the shape held in the data storage unit 14 are performed.

  If the feature point is not extracted (step S3, No), or if the shape of the detection area 21 does not approximate to the shape held in the data storage unit 14 (step S4, No), the contact with the input surface 100a is used. The process proceeds as if it were the person's finger (step S10).

  If the characteristic points are extracted (step S3, Yes) and it is determined that the shape of the detection region 21 approximates the shape held in the data storage unit 14 (step S4, Yes), the length a and the length are b, the normal direction, the position of the intersection F, and the position of the center of gravity O are calculated (step S5). A display object corresponding to the input device 200 is displayed based on the length a, the length b, the normal direction, the position of the intersection F, and the position of the center of gravity O (step S6).

  When the position of the detection area 21 changes while the display object is displayed (Yes in step S7), the normal direction, the position of the intersection F, and the position of the center of gravity O are calculated again (step S8). . The display object is changed according to the recalculated normal direction, the position of the intersection F, and the position of the center of gravity O (step S9). If the position of the detection area 21 does not change (step S7, No), the display object does not change.

The memory 302 is a RAM (Random Access Memory), a ROM (Read Only Memory), or the like. The memory 302 stores a program that executes the function of the data processing unit 13. The function of the data processing unit 13 is realized by the processor 301. The function of the data storage unit 14 is realized by the memory 302.

  According to the input system described above, since the first conductor portion 3 has a shape having directivity that is not rotationally symmetrical, one bottom surface 2a of the input device 200 is provided with one first conductor portion 3. For example, the orientation of the input device 200 can be grasped, and the display object according to the orientation can be displayed. Further, the center of gravity and size of the input device 200 can be grasped using the feature points, and the display object can be displayed at a position corresponding to the position and size of the center of gravity.

  Further, only one detection area is required to detect the contact with the input surface 100a. Therefore, even with the touch panel 100 in which the number of detection areas that can be detected at the same time is limited, it is possible to perform an operation that touches more places on the input surface 100a, in addition to the operation using the input device 200. Become.

  When a plurality of conductors are provided on the bottom surface of the input device and the direction of the input device is grasped based on the detection result of each conductor, it is necessary to secure a space for providing the plurality of conductors. Also, the contact of each of the plurality of conductors must be clearly detected. Therefore, it is necessary to provide the conductors sufficiently separated from each other, and the input device also becomes large. In the first embodiment, if the one first conductor portion 3 is provided, the direction and the like of the input device 200 can be grasped, so that the input device 200 can be downsized. FIG. 17 is a diagram showing a modification of the input device according to the first embodiment. As shown in FIG. 17, it is possible to reduce the size of the input device 200 by thinning the cylindrical portion where the second conductor portion 4 is provided.

  18 and 19 are diagrams showing modifications of the first conductor portion according to the first embodiment. As shown in FIGS. 18 and 19, the first conductor portion 3 may be formed in various shapes as long as it has a directivity that is not rotationally symmetrical.

The same components as those in the above-described embodiment are designated by the same reference numerals and detailed description thereof will be omitted. The input device 201 according to the second embodiment is provided with the third conductor portion 6. The third conductor portion 6 is provided at a position where the first conductor portion 3 is in contact with the input surface 100a and is not in contact with the input surface 100a.

  Even if the third conductor portion 6 is not in contact with the input surface 100a, the capacitance changes when the third conductor portion 6 approaches the input surface 100a. However, the change in capacitance is smaller than the change in capacitance that occurs when the first conductor portion 3 contacts the input surface 100a.

  It is possible to detect the position of the third conductor portion 6 by increasing the sensitivity of the detection device 101 that configures the input surface 100a, that is, by lowering the threshold value of the change in the detected capacitance. The detection area generation unit 130 also functions as a conductor detection unit that detects that the first conductor unit 3 has approached the input surface 100a. FIG. 21 is a diagram schematically showing a state in which the contact of the first conductor portion with the input surface and the proximity of the third conductor portion are detected in the second embodiment. The state in which the sensitivity of the detection device 101 is increased is referred to as the ID detection mode. The threshold value in the ID detection mode is the first threshold value.

  For example, the number of the third conductor portions 6, the positional relationship, or the distance d between the first conductor portion 3 and the third conductor portion 6 can be changed by the user. The data storage unit 14 holds information in which the number of the third conductor portions 6, the positional relationship, or the distance d between the first conductor portion 3 and the third conductor portion 6 and the display object are associated with each other. With such a configuration, different display objects can be displayed by the same input device 201 depending on the position of the first conductor portion 3 detected in the ID detection mode and the number, positional relationship, and number of the third conductor portions 6. It becomes possible to display. The objects that can be identified based on the number of the third conductor portions 6, the positional relationship, or the distance d between the first conductor portion 3 and the third conductor portion 6 are not limited to display objects. For example, the user may be identified by associating the number and the positional relationship of the third conductor portions 6 or the distance d between the first conductor portion 3 and the third conductor portion 6 with the user.

When the sensitivity of the detection device 101 is lower than that in the ID detection mode, that is, when the threshold value of the change in the detected capacitance is increased, the change in the capacitance caused by the third conductor portion 6 approaching the input surface 100a is suppressed. It will not be detected. On the other hand, the contact of the first conductor portion 3 having a large change in capacitance with the input surface 100a is detected. The operation mode is a state in which the sensitivity of the detection device 101 is low. The threshold value in the operation mode is the second threshold value. The second threshold is greater than the first threshold. In the operation mode, the operation according to the flowchart shown in FIG. 15 is possible.

  FIG. 22 is a diagram showing a relationship between sensitivity and time of the detection device according to the second embodiment. When the display object to be displayed is specified in the ID detection mode, the display object to be displayed can be specified while accepting the operation using the input device 201 by shifting to the operation mode. After that, when the operation in the operation mode is completed, the mode shifts to the ID detection mode again.

Embodiment 3.
FIG. 23 is a perspective view of the input device according to the third embodiment of the present invention. FIG. 24 is a sectional view of the input device according to the third embodiment. The same components as those in the above-described embodiment are designated by the same reference numerals and detailed description thereof will be omitted.

  In the input device 202 according to the third embodiment, the main body 2 has a through hole 2c penetrating toward the input surface 100a. The movable portion 7 is inserted into the through hole 2c. The movable portion 7 has a facing surface 7a facing the input surface 100a with the bottom surface 2a being in contact with the input surface 100a. The facing surface 7a is the third surface. A fourth conductor portion 8 is provided on the facing surface 7a. A conductor portion is also provided on the top surface 7b of the movable portion 7, and the conductor portion provided on the top surface portion 7b and the fourth conductor portion 8 are electrically connected. Therefore, when the user touches the top surface 7b, the fourth conductor portion 8 has the same potential as the human body of the user.

  The movable portion 7 is movable between a position where the facing surface 7a contacts the input surface 100a and a position where the facing surface 7a does not contact the input surface 100a with the bottom surface 2a of the main body 2 contacting the input surface 100a. ing.

  A biasing portion 9 is provided between the main body 2 and the movable portion 7. The urging unit 9 urges the movable unit 7 in a direction away from the input surface 100a. Therefore, when the external force is not applied to the movable portion 7 in the state where the first conductor portion 3 is in contact with the input surface 100a, the fourth conductor portion 8 provided in the movable portion 7 is separated from the input surface 100a. There is. When the user pushes the top surface 7b of the movable portion 7 against the urging force of the urging portion 9, the movable portion 7 moves toward the input surface 100a, and the fourth conductor portion 8 moves the input surface 100a. To contact.

  According to this configuration, in addition to the operation of rotating the input device 202 while bringing the first conductor portion 3 into contact with the input surface 100a, the movable portion 7 is pushed in to bring the fourth conductor portion 8 into contact with the input surface 100a. Operations can also be performed.

  For example, in the case where the display object is displayed as shown in FIG. 14, when the movable portion 7 is pushed to bring the fourth conductor portion 8 into contact with the input surface 100a, the color is different from that of the other buttons B. The button can be selected. Note that regardless of the type of display object, another application may be activated when the movable portion 7 is pushed to bring the fourth conductor portion 8 into contact with the input surface 100a. It should be noted that it is necessary to identify that it is the fourth conductor portion 8 that contacts the input surface 100a, not the finger. For example, it may be determined that the fourth conductor portion 8 has come into contact with the input surface 100a when the detection area 21 in which the contact has been detected overlaps the bottom surface size shown in FIG. Alternatively, the shape of the fourth conductor portion 8 is stored in advance, and when the shape of the detection region 21 matches the stored shape of the fourth conductor portion 8, the fourth conductor portion 8 becomes the input surface 100a. You may judge that it contacted.

  When the user stops pushing the movable portion 7 and the fourth conductor portion 8 separates from the input surface 100a, the operation according to the flowchart shown in FIG. 15 becomes possible. The input device 202 may also be provided with the third conductor 6 that does not contact the input surface 100a as in the second embodiment.

  The configurations shown in the above embodiments show an example of the content of the present invention, and can be combined with other known techniques, and the configurations of the configurations are possible without departing from the gist of the present invention. It is also possible to omit or change parts.
