The present invention relates to an input device capable of inputting information by using a change in electrostatic capacity.

Background

A touch panel is used which detects an operation on an input surface by using a change in capacitance.

SUMMERY OF THE UTILITY MODEL

In the input system disclosed in patent document 1, a plurality of conductors are provided in the input device in order to grasp the position and orientation of the input device. The number and intervals of contact portions on the input surface that can be simultaneously detected by the touch panel may be limited. In the input device disclosed in patent document 1, a plurality of conductors are brought into contact in order to grasp the position and orientation of the input device. In the input system using the input device as described above, there is a problem that another operation performed by contacting the input surface simultaneously with an operation using the input device is limited. For example, in an input system in which a touch panel having 3 contact portions that can be simultaneously detected and an input device provided with 3 conductors are combined, while an operation using the input device is performed, other contact portions cannot be detected. Therefore, it is impossible to perform other operations simultaneously with the operation using the input device. Further, since it is necessary to provide the input device at intervals at which 3 conductors are clearly recognized, it is difficult to realize a small-diameter input device such as a knob.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an input device capable of grasping the position and orientation of the input device through 1 conductor part and displaying a display object corresponding to an operation.

In order to solve the above problems and achieve the object, the present invention includes: a main body having a 1 st surface that contacts an input surface of the touch panel and a 2 nd surface that does not contact the input surface in a state where the 1 st surface contacts the input surface; a 1 st conductor part provided on the 1 st surface; and a 2 nd conductor part provided on the 2 nd surface. Characterized in that the 1 st conductor part and the 2 nd conductor part are electrically connected, and the 1 st conductor part has a shape having directivity capable of determining the orientation of the 1 st conductor part in the in-plane direction of the 1 st surface when viewed from the direction perpendicular to the 1 st surface.

Effect of the utility model

The input device according to the present invention has an effect that the position and orientation of the input device can be grasped by 1 conductor part, and the display object corresponding to the operation can be displayed.

Detailed Description

Hereinafter, an input device, an input-receiving device, and an input system according to embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, the present invention is not limited to the embodiment.

Embodiment 1.

Fig. 1 is a perspective view of an input system according to embodiment 1 of the present invention. The input system 1 has an input device 200 and an input-receiving device. The touch panel 100 shown in fig. 1 is a detection device and constitutes a part of an input device. The detailed configuration of the input device will be described later. The 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 superimposed, according to the position and type of the input device 200 that is in contact with the input surface 100 a. The display unit will be described later. In the input system 1, various display objects to be displayed are changed in accordance with a change in the orientation of the input device 200 in contact with the input surface 100 a.

First, the input device 200 will be explained. Fig. 2 is a perspective view of the input device according to embodiment 1. Fig. 3 is a side view of the input device according to embodiment 1. Fig. 4 is a plan view of the input device according to embodiment 1. Fig. 5 is a bottom view of the input device according to embodiment 1.

The input device 200 includes a main body 2 made of an insulating material. The main body 2 has a bottom surface 2a as a 1 st surface. The bottom surface 2a is a flat surface. As shown in fig. 5, in embodiment 1, the bottom surface 2a has a circular shape when viewed from a direction perpendicular to the bottom surface 2 a. In an input operation using the input device 200, the bottom surface 2a is in contact with the input surface 100a of the touch panel 100.

The main body 2 has a grip surface 2b as a 2 nd surface. In embodiment 1, the grip surface 2b is a cylindrical surface. In a state where the bottom surface 2a is in contact with the input surface 100a of the touch panel 100, the grip surface 2b is not in contact with the input surface 100a of the touch panel 100. The grip surface 2b is a portion gripped by a hand of a user who operates the input device 200.

A 1 st conductor portion 3 formed of a conductor is provided on a part of the bottom surface 2a of the main body 2. As shown in fig. 5, the 1 st conductor part 3 is provided to be in contact with the outer peripheral edge of the bottom surface 2 a. The 1 st conductor portion 3 has a shape having directivity capable of determining an in-plane direction of the bottom surface 2a when viewed from a direction perpendicular to the bottom surface 2 a. For example, the shape that is not rotationally symmetrical is a shape having directivity. The state in which the 1 st conductor portion 4 is present is set as an initial state. When the 1 st conductor 3 is rotated from the initial state within the plane of the bottom surface 2a, if the 1 st conductor 3 is not rotationally symmetrical, the 1 st conductor will not be overlapped with the initial state if the conductor is not rotated until the conductor returns to the initial state. Therefore, if the 1 st conductor portion 3 is not rotationally symmetrical, the orientation thereof can be determined. For example, if the 1 st conductor part 3 is a rotationally symmetrical square, it is overlapped with the initial state every 90 ° rotation in the plane of the bottom surface 2a, and therefore the orientation thereof cannot be determined. The 1 st conductor portion 3 has a shape having directivity by having a pentagonal shape which is not rotationally symmetrical as shown in fig. 5. Since the 1 st conductor 3 has a directional shape, if the positional relationship between the 1 st conductor 3 and the input device 200 is known, the position and the orientation of the input device 200 can be grasped from the position and the orientation of the 1 st conductor 3.

By associating the shape and size of the 1 st conductor part 3 with the type of the input device 200, the type of the input device 200 can be grasped if the shape and size of the 1 st conductor part 3 are grasped.

The grip surface 2b of the body 2 is provided with a 2 nd conductor portion 4 formed of a conductor. The 2 nd conductor portion 4 is provided over the entire circumference in the circumferential direction of the grip surface 2b as a cylindrical surface. Since the 2 nd conductor portion 4 is provided over the entire circumference along the circumferential direction of the grip surface 2b, the 2 nd conductor portion 4 is easily touched by the hand of the user when the user grips the grip surface 2 b.

The main body 2 is provided with a connection conductor portion 5 formed of a conductor and electrically connecting the 1 st conductor portion 3 and the 2 nd conductor portion 4. Since the 1 st conductor portion 3 and the 2 nd conductor portion 4 are electrically connected, if the hand of the user holding the holding surface 2b comes into contact with the 2 nd conductor portion 4, the 1 st conductor portion 3 has the same potential as the human body of the user. The connection conductor part 5 is not limited to be provided on the surface of the main body 2. If the 1 st conductor portion 3 and the 2 nd conductor portion 4 are electrically connected, the connection conductor portion 5 may be provided inside the main body 2. In the following description, the 1 st conductor portion 3 is in contact with the input surface 100a, which means that the grip surface 2b is gripped by the user and the 1 st conductor portion 3 having the same potential as the human body of the user is in contact with the input surface 100 a.

Next, the touch panel 100 will be explained. As shown in fig. 1, the touch panel 100 has an input surface 100 a. As the touch panel 100, if a human body or a conductor comes into contact with the input surface 100a, the position where the human body or the conductor comes into contact is grasped based on a change in electrostatic capacity.

The input surface 100a is a surface covering a display section described later. The display unit displays an image of a display object or the like. Various display objects displayed on the display unit can be visually recognized through the input surface 100 a. The touch panel 100 receives various input operations by contact of a display object displayed on the display unit with the input surface 100 a. For example, when it is detected that the finger of the user touches the area of the input surface 100a overlapping with the area where the number is displayed, it is determined that the input operation for selecting the number is performed. In the following description, the display that can be visually recognized on the display portion by the touch panel 100 will be simply referred to as displaying on the touch panel 100.

Next, the input device will be explained. Fig. 6 is a diagram showing a functional configuration of an input-target device according to embodiment 1. The input device 110 includes the detection device 101 and the information processing device 102. The detection device 101 is a touch panel 100.

The detection device 101 outputs contact information indicating that a human body or a conductor is in contact with the input surface 100a to the information processing device 102 based on a change in the capacitance. Fig. 7 is a diagram schematically showing an input surface of the detection device according to embodiment 1. Fig. 7 shows a state where the contact of the 1 st conductor portion 3 is detected. The 1 square of the lattice shown in fig. 7 is the minimum unit capable of detecting the contact of the conductor by the change in the electrostatic capacity. The contact information output from the detection device 101 is information indicating the position of a square where there is a change in capacitance. The information indicating the position of the square where the change in capacitance occurs is, for example, coordinate information.

The information processing device 102 includes a data storage unit 14, a detection device connection interface 11, a data processing unit 13, a display generation unit 15, and a display unit 16.

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

The shape storage unit 121 stores information indicating the shapes of the 1 st conductor parts 3 different from each other. Fig. 8 is a diagram showing another example of the shape of the 1 st conductor part in embodiment 1. The shape shown in fig. 8 is the same as the number of corners of the 1 st conductor part 3 having a pentagonal shape as illustrated in fig. 5, but the shape is different. The pentagonal shape shown in fig. 5 and the like is the shape of the pattern 1, and the shape shown in fig. 8 is the shape of the pattern 2.

The setting storage unit 122 stores information for specifying the input device 200 based on the shape of the 1 st conductor unit 3. Fig. 9 is a diagram showing information stored in the setting storage unit in embodiment 1. 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 connect with the detection device 101. The contact information output from the detection device 101 is input to the data processing unit 13 via the detection device connection interface 11.

The data processing unit 13 includes a detection region generating unit 130, a feature point extracting unit 131, a shape determining unit 132, and a size calculating unit 133. The detection area generating unit 130 determines an area where a human body or a conductor is in contact with the detection device 101 based on information input to the data processing unit 13.

The detection area generating unit 130 generates the detection area 21, which is an area where contact with the input surface 100a exists, based on the contact information, that is, information indicating the position of the square where the change in capacitance exists. The detection region generating unit 130 functions as a conductor detecting unit for detecting contact between the 1 st conductor unit 3 and the input surface 100 a. The detection region generation unit 130 determines that a block having a change in capacitance exceeding a threshold value is a region where contact is present, and generates the detection region 21. When the 1 st conductor 3 is in contact with the input surface 100a, the shape of the detection region 21, which is an aggregate of squares having a change in capacitance, is also a shape close to a pentagon, which is the shape of the 1 st conductor 3.

The feature point extracting unit 131 extracts a corner portion as a feature point from the shape of the detection region 21. Fig. 10 is a diagram showing an example of detection of the characteristic point in a state where the contact of the 1 st conductor part shown in fig. 7 is detected. As shown in fig. 10, 5 feature points a to E are extracted from a detection region 21 of a pentagonal shape generated by the contact of the 1 st conductor part 3. The 5 feature points a to E are extracted as coordinate information.

The shape determination unit 132 determines which shape of the plurality of shapes stored in the data storage unit 14 the shape of the detection region 21 is approximate to, based on the coordinate information of the extracted feature points a to E. When determining that the shape of the detection region 21 is not similar to any of the plurality of shapes stored in the data storage unit 14 or when the feature point is not extracted, the shape determination unit 132 determines that the finger of the user is in contact with the detection device 101. As shown in fig. 10, if the shape in which the feature points a to E are connected by a line is a pentagonal shape, the shape determination unit 132 determines that the detection area 21 is similar to the shape stored in the storage unit when the data storage unit also stores information on the pentagonal shape.

When determining that the shape of the detection region 21 is similar to the shape stored in the storage unit, the size calculation unit 133 calculates the length a, which is the distance between the feature point a and the feature point B, using the coordinates of the feature point a and the coordinates of the feature point B. The length a is the length of the 1 st conductor part 3 along the outer periphery of the bottom surface 2a of the input device 200. The size calculation unit 133 calculates a normal direction indicated by an arrow G in fig. 10. The normal direction G is defined in the shape of the detection region 21 shown in fig. 10 as a direction from an intersection F between a line connecting the feature point a and the feature point C and a line connecting the feature point B and the feature point E toward the feature point D.

Here, information stored in the setting storage unit 122 shown in fig. 9 will be described. The information stored in the setting storage unit 122 is associated with the type of the input device 200, the shape, length a, and length b of the 1 st conductor unit 3, and the type of the display object.

The type of the input device 200 is stored in information such as No1 and No 2. The shape of the 1 st conductor 3 is stored by information such as the pattern 1 and the pattern 2.

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

The type of display object indicates the type of display object displayed when the input device 200 is in contact with the input surface 100 a. Fig. 12 is a diagram showing an example of display on a touch panel in the input system according to embodiment 1. In fig. 12, a circular arc-shaped bar graph is shown around the input device 200. The arc-shaped histogram is a display object of the pattern V shown in fig. 9. In the display object of the pattern V, colors and the like are different on one end side and the other end side of the histogram. In fig. 12, the difference in color or the like is indicated by the presence or absence of shading.

Fig. 13 is a diagram showing another example of display on the touch panel in the input system according to embodiment 1. In fig. 13, an arc-shaped histogram is displayed around the input device 200, and A, B, C, D, E is displayed from one end side of the histogram to the other end side. The arc-shaped histogram displayed in A, B, C, D, E is the display target of the pattern W shown in fig. 9. Further, a pointer indicating which region A, B, C, D, E is selected is displayed on the outer side of the arc-shaped histogram displayed at A, B, C, D, E.

Fig. 14 is a diagram showing another example of display on the touch panel in the input system according to embodiment 1. In fig. 14, a plurality of buttons are displayed on the side of the input device 200. The buttons are each displayed at A, B, C, D. The button that has been displayed with A, B, C, D is the display target of pattern X shown in fig. 9. The button displayed at A, B, C, D changes its color or the like from the other buttons, and it can be determined which button has been selected. In fig. 14, the state in which the button displayed as B is selected is shown by showing the presence or absence of a difference in color or the like by hatching.

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

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, the processing in the case where No.1 input device 200 shown in fig. 9 is in contact with 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 having the length a of "10" and the length b of "20" is the input device of No. 1. The display generation unit 15 causes the display unit 16 to display the display object of the pattern V. Specifically, the histogram shown in fig. 12 is displayed on the 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 position O output from the data processing unit 13, and determines the position at which the histogram is displayed. The display generation unit 15 detects the orientation of the input device 200 using the information indicating the normal direction output from the data processing unit 13, and determines the size of the region having a different color in the histogram in accordance with the orientation. The display generation unit 15 displays a histogram having different colors in the determined area size on the touch panel 100. The display generation unit 15 also functions as a direction determination unit that determines the direction of the 1 st conductor unit 3. In fig. 12, the input device 200 is rotated in the direction indicated by the arrow P, and the orientation of the input device 200 is changed.

If 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 outputs the information to the display generation unit 15. The display generation unit 15 changes the size of the region where the position and color of the histogram are different and displays the region on the display unit 16 based on the information indicating the normal direction and the information indicating the position of the center of gravity position O, which are output again from the data processing unit 13. For example, if the size of the region in the histogram in which the colors are made different is associated with a numerical value, it is possible to input the numerical value corresponding to the rotation of the input device 200 to the external apparatus through the input system 1. For example, when the input system 1 is provided in a processing device as an external device, the size of the region in which the colors are different in the histogram and a numerical value indicating the processing speed of the processing device are associated with each other, and the numerical value can be increased or decreased by rotating the input device 200 to change the processing speed. That is, the user can operate the input device 200 like a dial that changes an input value by a rotation operation.

When the input device 200 of No.2 is in contact with the input surface 100a, a bar graph in which A, B, C, D, E is displayed as a display object of the pattern W is displayed. The position of the display object indicating which region A, B, C, D, E has been selected changes in accordance with the change in the orientation of the input device 200.

When the input device 200 of No.3 is in contact with the input surface 100a, the button displaying the pattern X, that is, displaying A, B, C, D is displayed. The button having a different color is changed in accordance with the change in the orientation of the input device 200 to indicate which button has been selected.

Fig. 15 is a flowchart showing a procedure of displaying a display object on a touch panel using an input device in the input system according to embodiment 1. The detection device 101 monitors the presence or absence of a change in capacitance. If the change in capacitance is detected (step S1), the coordinate information of the detection region 21 indicating that there is a change in capacitance on the input surface 100a is output to the data processing unit 13 (step S2). Next, the feature points of the detection area 21 are extracted, and whether or not the shape of the detection area 21 is similar to the shape stored in the data storage unit 14 is determined.

If the feature point is not extracted (No at step S3) and the shape of the detection region 21 is not similar to the shape stored in the data storage unit 14 (No at step S4), the user' S finger is in contact with the input surface 100a and the processing is performed (step S10).

When the feature point is extracted (Yes at step S3) and it is determined that the shape of the detection region 21 is similar to the shape stored in the data storage unit 14 (Yes at step S4), the length a, the length 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 position O (step S6).

When the position of the detection region 21 changes while the display object is displayed (Yes at 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 object change is displayed in accordance with the recalculated normal direction, the position of the intersection F, and the position of the center of gravity position O (step S9). If the position of the detection region 21 does not change (No at step S7), the display object does not change.

Fig. 16 is a diagram showing a hardware configuration of the information processing apparatus according to embodiment 1. The information processing apparatus 102 can be realized by the processor 301, the memory 302, and the display unit 16 shown in fig. 16. The processor 301 is a CPU (also referred to as a Central Processing Unit, arithmetic Unit, microprocessor, microcomputer, dsp (digital Signal processor), system lsi (large Scale integration), or the like. The memory 302 is a ram (random Access memory), a rom (read Only memory), or the like. The memory 302 stores a program for executing the function of the data processing unit 13. The function of the data processing section 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 1 st conductor portion 3 has a non-rotationally symmetrical directivity, if the 1 st conductor portion 3 is provided on the bottom surface 2a of the input device 200, the orientation of the input device 200 can be grasped, and a display object corresponding to the orientation can be displayed. Further, the center of gravity and the size of the input device 200 can be grasped using the feature points, and the display object can be displayed at a position matching the position and the size of the center of gravity.

In addition, the number of detection areas for detecting contact with the input surface 100a may be 1. Therefore, even in the touch panel 100 in which the number of simultaneously detectable detection regions is limited, in addition to the operation using the input device 200, the operation of contacting more portions of the input surface 100a can be performed.

When a plurality of conductors are provided on the bottom surface of the input device and the orientation of the input device is grasped based on the detection results of the conductors, it is necessary to secure a space for providing the plurality of conductors. In addition, the contact of each of the plurality of conductors needs to be detected clearly. Therefore, the conductors need to be sufficiently separated from each other, and the input device is also large-sized. In embodiment 1, if 1 of the 1 st conductor portions 3 is provided, the orientation and the like of the input device 200 can be grasped, and therefore the input device 200 can be downsized. Fig. 17 is a diagram showing a modification of the input device according to embodiment 1. As shown in fig. 17, the input device 200 can be downsized by making the cylindrical portion provided for the 2 nd conductor portion 4 thin.

Fig. 18 and 19 are views showing modifications of the 1 st conductor part in embodiment 1. As shown in fig. 18 and 19, if the conductor 1 is formed in a shape having directivity that is not rotationally symmetrical, the conductor 3 can be formed in various shapes.

Embodiment 2.

Fig. 20 is a sectional view of an input device according to embodiment 2 of the present invention. Note that the same components as those of the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The input device 201 according to embodiment 2 is provided with the 3 rd conductor part 6. The 3 rd conductor portion 6 is provided at a position not in contact with the input surface 100a in a state where the 1 st conductor portion 3 is in contact with the input surface 100 a.

Even if the 3 rd conductor part 6 does not contact the input surface 100a, the capacitance changes as the 3 rd conductor part 6 approaches the input surface 100 a. However, the change in capacitance is smaller than that caused by the contact of the 1 st conductor portion 3 with the input surface 100 a.

The position of the 3 rd conductor part 6 can be detected by increasing the sensitivity of the detection device 101 constituting the input surface 100a, that is, by lowering the threshold value of the change in capacitance to be detected. The detection region generating unit 130 also functions as a conductor detecting unit that detects the approach of the 1 st conductor unit 3 to the input surface 100 a. Fig. 21 is a diagram schematically showing a state in which the contact of the 1 st conductor part with the input surface and the approach of the 3 rd conductor part are detected in embodiment 2. The state in which the sensitivity of the detection device 101 is increased is set as the ID detection mode. The threshold of the ID detection mode is set to the 1 st threshold.

For example, the user can make the number and positional relationship of the 3 rd conductor parts 6 or the distance d between the 1 st conductor part 3 and the 3 rd conductor part 6 different. Information relating to the number and positional relationship of the 3 rd conductor part 6 or the distance d between the 1 st conductor part 3 and the 3 rd conductor part 6 and the display object is stored in the data storage part 14. With the above configuration, even the same input device 201 can display different display objects by the number, positional relationship, and number of the 1 st conductor part 3 and the 3 rd conductor part 6 detected in the ID detection mode. The objects that can be recognized based on the number and positional relationship of the 3 rd conductor portions 6 or the distance d between the 1 st conductor portion 3 and the 3 rd conductor portion 6 are not limited to the display objects. For example, the number and positional relationship of the 3 rd conductor part 6 or the distance d between the 1 st conductor part 3 and the 3 rd conductor part 6 may be associated with the user, so that the user can be identified.

If the sensitivity of the detection device 101 is lowered, that is, if the threshold for the change in capacitance to be detected is increased, as compared with the ID detection mode, the change in capacitance due to the proximity of the 3 rd conductor portion 6 to the input surface 100a is not detected. On the other hand, the contact of the 1 st conductor portion 3 with a large change in capacitance with the input surface 100a is detected. The state in which the sensitivity of the detection device 101 is reduced is set as the operation mode. The threshold in the operation mode is set to the 2 nd threshold. The 2 nd threshold is less than the 1 st threshold. In the operation mode, an operation along the flowchart shown in fig. 15 can be performed.

Fig. 22 is a graph showing the relationship between the sensitivity and time of the detection device in embodiment 2. If the display object to be displayed is identified in the ID detection mode, the operation mode is switched to the operation mode, whereby the operation using the input device 201 can be accepted and the display object to be displayed can be identified. Then, if the operation in the operation mode is completed, the ID detection mode is shifted again.

Embodiment 3.

Fig. 23 is a perspective view of an input device according to embodiment 3 of the present invention. Fig. 24 is a sectional view of the input device according to embodiment 3. Note that the same components as those in the above embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

In the input device 202 according to embodiment 3, a through hole 2c penetrating toward the input surface 100a is formed in the main body 2. The movable portion 7 is inserted into the through hole 2 c. The movable portion 7 has a facing surface 7a facing the input surface 100a with the bottom surface 2a in contact with the input surface 100 a. The opposing surface 7a is the 3 rd surface. The 4 th conductor part 8 is provided on the facing surface 7 a. A conductor portion is further provided on the top surface 7b of the movable portion 7, and the conductor portion provided on the top surface portion 7b is electrically connected to the 4 th conductor portion 8. Therefore, the user touches the top surface 7b, and the 4 th conductor part 8 is set to the same potential as the human body of the user.

The movable portion 7 can move to a position where the opposing surface 7a contacts the input surface 100a and a position where the opposing surface 7a does not contact the input surface 100a in a state where the bottom surface 2a of the main body 2 contacts the input surface 100 a.

An urging portion 9 is provided between the main body 2 and the movable portion 7. The biasing portion 9 biases the movable portion 7 in a direction away from the input surface 100 a. Therefore, if no external force is applied to the movable portion 7 in a state where the 1 st conductor portion 3 is in contact with the input surface 100a, the 4 th conductor portion 8 provided in the movable portion 7 is separated from the input surface 100 a. When the user pushes the top surface 7b of the movable portion 7 against the biasing force of the biasing portion 9, the movable portion 7 moves in a direction approaching the input surface 100a, and the 4 th conductor portion 8 comes into contact with the input surface 100 a.

According to this configuration, in addition to the operation of rotating the input device 202 while bringing the 1 st conductor portion 3 into contact with the input surface 100a, the operation of pressing the movable portion 7 into contact with the 4 th conductor portion 8 with the input surface 100a can be performed.

For example, as shown in fig. 14, when the movable portion 7 is pushed in and the 4 th conductor portion 8 is brought into contact with the input surface 100a when the display object is displayed, the button B having a color different from that of the other buttons can be selected. Further, regardless of the type of the display object, when the movable portion 7 is pushed in and the 4 th conductor portion 8 is brought into contact with the input surface 100a, another application may be started. Further, it is necessary to identify not the finger but the 4 th conductor part 8 which is in contact with the input surface 100 a. For example, when the detection region 21 in which contact is detected is a region overlapping the bottom surface size shown in fig. 11, it can be determined that the 4 th conductor part 8 is in contact with the input surface 100 a. Alternatively, the shape of the 4 th conductor part 8 may be stored in advance, and when the shape of the detection region 21 matches the stored shape of the 4 th conductor part 8, it may be determined that the 4 th conductor part 8 is in contact with the input surface 100 a.

When the user stops pushing the movable portion 7 and separates the 4 th conductor portion 8 from the input surface 100a, the operation according to the flowchart shown in fig. 15 can be performed. The input device 202 may be provided with the 3 rd conductor 6 which is not in contact with the input surface 100a as in embodiment 2.

The configuration described in the above embodiment is an example of the contents of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or changed without departing from the scope of the present invention.
