Description

Input device

This disclosure relates to an input device.

Conventionally, for example, in a rotation operation type input device, a lower case that holds a fixed electrode and a movable electrode are held and rotated with respect to the lower case to rotate the movable electrode relative to the fixed electrode. An input device including a rotating body is known (see, for example, Patent Document 1). In such an input device, a metal click spring is built in to give a click feeling at each predetermined rotation angle when the rotating body is rotated by the user.

International Publication No. 2016/975907

In recent years, in order to improve the design, it has been required that the input device be formed so as to have translucency as a whole. However, since the click spring built in the input device is made of metal, the actual situation is that the light transmitted through the input device is blocked.

An object of the present disclosure is to provide an input device that can realize a click feeling without using a metal click spring and can enhance the translucency inside the device.

In the input device according to one aspect of the present disclosure, the first electrode, the support supporting the first electrode, the fixed body fixed to the support, the second electrode, and the second electrode are designated as the first electrode. By holding, rotating or moving the second electrode with a space between them, the second electrode can be moved closer to or further away from the first electrode, and the moving body can be engaged with the moving body to form a fixed body. On the other hand, it is an operating body that is held in a fixed body so as to be relatively movable, and is arranged between the moving body and the fixed body to rotate or move the moving body by being operated by the user. The moving body is provided with an urging portion that applies an urging force to the support side to the moving body, and the moving body has a plurality of concave portions recessed in a direction orthogonal to the moving direction in which the moving body moves and a plurality of convex portions protruding in the direction. The portions have a concavo-convex structure in which the portions are continuously and alternately arranged along the moving direction, and the urging portions are arranged between the elastic body for applying the urging force and the concavo-convex structure and the elastic body. It has a pressing body that elastically deforms the elastic body in conjunction with the movement of the moving body, and a holding body that is fixed to the fixed body and holds the elastic body and the sphere in a variable manner. The moving body, the operating body, the elastic body, the pressing body, and the holding body have translucency.

In the input device according to one aspect of the present disclosure, the first electrode, the support supporting the first electrode, the fixed body fixed to the support, the second electrode, and the second electrode are designated as the first electrode. In a state of being engaged with a moving body that moves the second electrode closer to or further away from the first electrode in the direction of movement by holding, rotating or moving in a state of facing each other at intervals. An operating body that is held in the fixed body so as to be relatively movable with respect to the fixed body, and is arranged between the moving body and the fixed body with the operating body that rotates or moves the moving body by being operated by the user. The moving body is provided with an urging portion that applies an urging force to the support side to the moving body, and the moving body has a plurality of recesses recessed in a direction orthogonal to the moving direction in which the moving body moves and projects in the direction thereof. A plurality of convex portions have a concavo-convex structure in which a plurality of convex portions are continuously and alternately arranged along a moving direction, and the urging portion is between an elastic body for applying an urging force and the concavo-convex structure and the elastic body. It has a pressing body that is arranged and elastically deforms the elastic body in conjunction with the movement of the moving body, and a holding body that is fixed to the fixed body and holds the elastic body and the pressing body in a variable manner. The fixed body, the moving body, the operating body, the elastic body, the pressing body, and the holding body have translucency.

According to this, since the elastic body, the pressing body, and the holding body, which are structures for giving a click feeling to the operating body, have translucency, the click spring made of metal is not required. It is possible to enhance the translucency inside the input device while realizing a click feeling.

In particular, since the support, fixed body, moving body, operating body, elastic body, pressing body, and holding body forming the input device have translucency, the input device 10 as a whole can be optically produced. ..

Further, the holding body is formed with a concave relief portion that receives elastic deformation of the elastic body, and the relief portion is formed at a portion opposite to the pressing body with the elastic body as a reference.

According to this, since the holding body is provided with a concave relief portion that receives elastic deformation of the elastic body, the internal space of the relief portion becomes a space for the elastic body to escape. Therefore, elastic deformation of the elastic body can be promoted, and even a thin elastic body can be smoothly elastically deformed and elastically restored. Therefore, the elastic body can be made thin.

Further, the concave-convex structure is arranged closer to the support than the holding body, and the pressing body and the elastic body are arranged in this order on the uneven structure.

According to this, since the pressing body and the elastic body are arranged in this order on the uneven structure, the urging force toward the support caused by the elastic body is applied to the moving body via the pressing body and the uneven structure. Can be granted. Therefore, the urging force toward the support can be reliably applied to the moving body.

In addition, the pressing body moves up and down in conjunction with the moving uneven structure. When the pressing body is irradiated with light, it may be diffusely reflected and flicker due to its ascending / descending motion. In the present embodiment, since the elastic body is arranged outside the pressing body, the flicker caused by the pressing body is less noticeable. As a result, the optical effect can be enhanced.

In addition, the portion of the pressing body in contact with the concave-convex structure is curved so as to bulge toward the concave-convex structure.

According to this, since the portion of the pressing body in contact with the uneven structure is curved so as to protrude toward the uneven structure side, the pressing body can be rolled on the uneven structure.

Also, the pressing body is a sphere.

According to this, since the pressing body is a sphere, the sphere can be moved smoothly on the uneven structure, and smooth operability can be realized.

Further, the first electrode has a reference potential electrode and two or more sets of transmitting and receiving electrodes, and the reference potential electrode is at least one set of transmitting and receiving electrodes out of two or more sets of transmitting and receiving electrodes. As a result of the second electrode approaching the electrode, two or more sets of transmit and receive electrodes face at least a part of the second electrode, and the first set of transmit and receive electrodes are arranged in the first region. And the second set of transmitting and receiving electrodes arranged in the second region, and the phase when the first set of transmitting and receiving electrodes approaches or moves away from the second electrode is the second. The pair of transmit and receive electrodes are out of phase when approaching or moving away from the second electrode.

According to this, the second electrode rotates or moves in a state of facing the first electrode at a predetermined interval in a moving direction with respect to at least two sets of the transmitting electrode and the receiving electrode. Approach or move away. Therefore, the electrical state between the first electrode and the second electrode changes during rotation or movement. By detecting this change in the electrical state, it is possible to detect the relative movement amount between the first electrode and the second electrode even without the third electrode. Since the first electrode and the second electrode face each other with a predetermined interval even during relative movement, friction does not occur. Therefore, damage to the first electrode and the second electrode can be suppressed, and the quality can be maintained for a long period of time.

Further, the pair of transmitting and receiving electrodes arranged in the first region and the set of transmitting and receiving electrodes arranged in the second region have different phases when approaching or moving away from the second electrode. ing. Therefore, the phase is different from the change in the electric state caused by the first set and the change in the electric state caused by the second set. By detecting this phase difference, it is possible to detect the direction of rotation as well.

Further, the reference potential electrode does not have to face a part of the second electrode when the second electrode does not approach at least one set of the transmitting electrode and the receiving electrode.

Further, the reference potential electrode may face a part of the second electrode even when the second electrode does not approach at least one set of the transmitting electrode and the receiving electrode.

Further, when the second electrode approaches at least one set of the transmitting electrode and the receiving electrode, the area of the portion of the reference potential electrode facing the second electrode may increase.

[Embodiment]
The embodiments described below are all specific examples of the present disclosure. Numerical values, shapes, materials, components, arrangement positions and connection forms of components, steps, order of steps, etc. shown in the following embodiments are examples, and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, the components not described in the independent claims indicating the embodiment according to the present disclosure will be described as arbitrary components. The embodiment of the present disclosure is not limited to the current independent claims, but may be expressed by other independent claims.

[Structure of input device]
FIG. 1 is a perspective view showing a schematic configuration of an input device 10 according to an embodiment. FIG. 2 is an exploded perspective view of the input device 10 according to the embodiment. FIG. 3 is an exploded perspective view of the input device 10 according to the embodiment as viewed from a direction different from that of FIG. FIG. 4 is a cross-sectional view of the input device 10 according to the embodiment. Specifically, FIG. 4 is a cross-sectional view of the cut surface including the IV-IV line in FIG. In the following description, for convenience of explanation, the operating body 50 side is described as upward and the touch sensor 200 side is described as downward, but this is merely an example, and the above-described position may be used depending on the installation mode (posture) of the input device 10. It may not be a relationship.

As shown in FIGS. 1 to 4, the input device 10 is installed on the touch sensor 200, and is a device that detects the amount of rotational movement by rotating the touch sensor 200. Specifically, the input device 10 has a support 20, a fixed body 30, a moving body 40, an operating body 50, an urging portion 60, a first electrode 70, and a second electrode 80. ing.

The support 20 is a substrate made of a translucent resin. In the present embodiment, the support 20 is shared with the substrate of the touch sensor 200. Therefore, an electrode pattern for multipoint detection (not shown) and a first electrode 70 for the input device 10 are formed on at least one of the pair of main surfaces of the support 20 to support the support. Has been done. The electrode pattern and the first electrode 70 are transparent electrodes made of, for example, ITO. As described above, the first electrode 70 is the electrode of the touch sensor 200. The main surface of the support 20 is covered with a cover lens 21 made of a translucent member such as glass. The second electrode 80 is arranged at a position facing the first electrode 70 with the cover lens 21 interposed therebetween. A translucent adhesive layer (not shown) is interposed between the layers, and each member is adhered by the adhesive layer.

Here, on the back side of the touch sensor 200, a display panel 300 as an image display unit for displaying an image is arranged. The display panel 300 is a liquid crystal panel, an organic EL panel, or the like. An electrical shielding layer 400 is arranged between the display panel 300 and the touch sensor 200. That is, it can be said that the shielding layer 400 is arranged on the opposite side of the first electrode 70 from the second electrode 80. The shielding layer 400 can shield electrical noise from the display panel 300 arranged on the back side of the input device 10. Therefore, the shielding layer 400 may be arranged at least in a region overlapping the entire first electrode 70. However, if the shielding layer 400 is arranged in a wider range than the first electrode 70, it is possible to exert a higher noise reduction effect. The shielding layer 400 is a transparent electrode made of, for example, ITO.

The fixed body 30 is a member fixed on the main surface of the support body 20. The fixed body 30 is formed in a cylindrical shape by, for example, a translucent resin. A pair of notches 31 are formed at positions facing each other at the upper end portion of the fixed body 30. An annular convex portion 32 continuous over the entire circumference is formed in the lower portion of the outer peripheral surface of the fixed body 30.

The moving body 40 is a member that rotates with respect to the fixed body 30. The moving body 40 is formed in a bottomed cylindrical shape by, for example, a translucent resin. The moving body 40 is arranged so as to be concentric with the fixed body 30. That is, the center of rotation of the moving body 40 and the center of the fixed body 30 are arranged coaxially.

At the upper end of the moving body 40, a pair of notches 45 are formed at positions facing each other with the rotation center in between. On the outer periphery of the bottom side of the moving body 40, a collar portion 41 protruding outward is provided over the entire circumference. An uneven structure 42 is formed on the upper surface of the collar portion 41. In the concave-convex structure 42, a plurality of concave portions 43 recessed in a direction orthogonal to the moving direction (rotational direction) of the moving body 40 and a plurality of convex portions 44 protruding in the direction are arranged alternately and continuously along the moving direction. ing. Specifically, the concave portion 43 is recessed downward in a concave curved surface shape, and the convex portion 44 is projected upward in a convex curved surface shape. The upper surface of the concave-convex structure 42, that is, the upper surface of the flange portion 41 has a smoothly wavy shape.

A second electrode 80 is attached to the lower surface of the moving body 40. The second electrode 80 is a transparent electrode made of, for example, ITO. A cover lens 21 is interposed between the second electrode 80 and the first electrode 70, and the second electrode 80 and the first electrode 70 are in a state of facing each other with a predetermined interval. That is, the moving body 40 holds the second electrode 80 in a state of facing the first electrode 70 at a predetermined interval.

The moving body 40 rotates in conjunction with the operation of the operating body 50 by the user, and even during this rotational movement, the second electrode 80 and the first electrode 70 face each other with a predetermined interval. It is in a state. Due to the rotational movement of the moving body 40, a part of the second electrode 80 repeatedly approaches or moves away from the first electrode 70 in the moving direction.

The operating body 50 is a member that is held so as to be relatively movable with respect to the fixed body 30 in a state of being engaged with the moving body 40. The operating body 50 is a member that rotates the moving body 40 when operated by the user. Specifically, the operating body 50 is formed in a cylindrical shape by, for example, a translucent resin. The operating body 50 is arranged so as to be concentric with the moving body 40. That is, the center of rotation of the operating body 50, the center of rotation of the moving body 40, and the center of rotation of the moving body 40 are arranged coaxially. An annular top plate 51 extending inward over the entire circumference is formed at the upper end of the operating body 50.

FIG. 5 is an enlarged cross-sectional view showing a part of the input device 10 according to the embodiment. As shown in FIG. 5, the top plate portion 51 is a lid portion that closes the space between the fixed body 30 and the moving body 40. The inner peripheral surface of the top plate portion 51 is arranged flush with respect to the inner peripheral surface of the moving body 40. The lower surface of the top plate portion 51 has a stepped shape such that the inner peripheral portion 511 is above the outer peripheral portion 512. The outer peripheral portion 512 of the top plate portion 51 is in contact with the upper surface of the fixed body 30, which restricts the downward movement of the operating body 50. On the other hand, the inner peripheral portion 511 of the top plate portion 51 is separated from the upper surface of the moving body 40. As a result, the axial force is not applied from the operating body 50 to the moving body 40.

On the inner peripheral surface of the top plate portion 51, a plurality of claw portions 53 that engage with the annular convex portion 32 of the fixed body 30 are arranged at predetermined intervals in the circumferential direction. The claw portion 53 is a portion protruding inward from the inner peripheral surface of the top plate portion 51. The claw portion 53 is arranged below the annular convex portion 32 so as to overlap the annular convex portion 32 of the fixed body 30 in the axial direction. Even if the operating body 50 rises and is about to be separated from the fixed body 30, the claw portion 53 is locked by abutting on the annular convex portion 32. That is, the structure is such that the operating body 50 does not come off from the fixed body 30. Further, since the claw portion 53 and the annular convex portion 32 are not mutually regulated in the circumferential direction, the operating body 50 is held so as to be relatively movable with respect to the fixed body 30. Since the lower surface of the claw portion 53 is an inclined surface that inclines outward as it goes downward, when the operating body 50 is assembled to the fixed body 30, the inclined surface is guided by the annular convex portion 32. The operating body 50 is smoothly elastically deformed. When the claw portion 53 passes through the annular convex portion 32, the operating body 50 returns to its original shape.

As shown in FIG. 4, on the lower surface of the top plate portion 51, a pair of convex pieces 52 projecting downward are arranged at positions facing each other. The convex piece 52 is fitted in the notch 45 of the moving body 40. As a result, the rotational movement of the operating body 50 is transmitted to the moving body 40 via the convex piece 52 and the notch 45, and the moving body 40 rotates. The notch 45 of the moving body 40 is a portion to which an acting force is applied from the operating body 50 when the operating body 50 moves.

As shown in FIGS. 2 to 5, the urging portion 60 is a portion that is arranged between the moving body 40 and the fixed body 30 and imparts urging force to the support 20 side to the moving body 40. is there. The urging portion 60 is arranged at a position different from that of the notch 45. As a result, the acting force from the operating body 50 and the urging force from the urging unit 60 are independently applied to the moving body 40 at different locations.

Specifically, the urging portion 60 has a holding body 61, an elastic body 62, and a sphere 63.

The holding body 61 is a member that is fixed to the fixed body 30 and variably holds the elastic body 62 and the sphere 63. Specifically, the holding body 61 is, for example, a member formed in a circular shape by a translucent resin. The holding body 61 is arranged so as to be concentric with the moving body 40. That is, the center of the holding body 61 and the center of rotation of the moving body 40 are arranged coaxially.

At the upper end of the holding body 61, a pair of protrusions 611 fitted to each notch 31 of the fixed body 30 are formed at positions facing each other with the rotation center interposed therebetween. The pair of protrusions 611 project outward from the outer peripheral surface of the holding body 61. The holding body 61 is fixed to the fixed body 30 by fitting the pair of protrusions 611 into each notch 31 of the fixed body 30.

Further, a pair of slits 612 whose lower surface is open is formed on the lower surface of the holding body 61. The pair of slits 612 are located at positions different from the pair of protrusions 611, and are arranged at positions facing each other with the center of rotation interposed therebetween. An elastic body 62 and a sphere 63 are housed in each slit 612. That is, a pair of elastic body 62 and sphere 63 is provided. Each slit 612 is arranged at a position overlapping the flange portion 41 of the moving body 40. That is, since each slit 612 overlaps the outer peripheral portion of the moving body 40, the elastic body 62 and the sphere 63 accommodated in each slit 612 also overlap the outer peripheral portion of the moving body 40.

As shown in FIG. 5, the upper portion of the slit 612 is formed in a truncated cone shape that tapers toward the top. An elastic body 62 is attached below the truncated cone-shaped portion. The portion of the slit 612 above the elastic body 62 is a relief portion 64 that receives elastic deformation when the elastic body 62 is pressed upward. The relief portion 64 is formed in the truncated cone shape described above, but in other words, it is formed in a concave shape that is recessed upward. The internal space of the relief portion 64 is a space for the elastic body 62 to escape. Due to such a space, elastic deformation of the elastic body 62 is promoted, and the elastic body 62 can be smoothly elastically deformed and elastically restored. Further, since the relief portion 64 has a tapered shape, it is possible to secure the wall thickness around the relief portion 64 while undergoing elastic deformation of the elastic body 62. Thereby, it is possible to suppress the vulnerability of the holding body 61 due to the slit 612.

The elastic body 62 is, for example, a plate body made of a translucent resin. The elastic body 62 is a member having lower rigidity than other members (support 20, fixed body 30, moving body 40, operating body 50, holding body 61, and sphere 63). Specifically, the elastic body 62 is formed of a translucent silicone resin. The elastic body 62 may be formed of a translucent material having elasticity, or may be formed in a shape exhibiting elasticity by using a translucent material. In the slit 612, a sphere 63 is rotatably arranged below the elastic body 62.

The sphere 63 is an example of a pressing body that elastically deforms the elastic body 62 in conjunction with the movement of the moving body 40. The sphere 63 is, for example, a sphere formed of a translucent resin. The sphere 63 is placed on the upper surface of the concave-convex structure 42 in the moving body 40. As described above, the sphere 63, the elastic body 62, and the holding body 61 are arranged upward in this order on the uneven structure 42. Since they are arranged in this order, the urging force toward the support 20 caused by the elastic body 62 can be applied to the moving body 40 via the sphere 63 and the concave-convex structure 42.

Specifically, when the moving body 40 rotates with respect to the fixed body 30 and the holding body 61, the concave portions 43 and the convex portions 44 of the concave-convex structure 42 pass alternately under the sphere 63. Therefore, the sphere 63 fluctuates up and down.

For example, in a state where the recess 43 is directly below the sphere 63, as shown in FIG. 5, the sphere 63 is lowered and does not push up the elastic body 62. The elastic body 62 retains its original shape. On the other hand, when the recess 43 separates from directly below the sphere 63, the sphere 63 gradually rises following the wavy shape of the upper surface of the concave-convex structure 42. As the sphere 63 pushes up the elastic body 62 with this rise, the elastic body 62 is elastically deformed. When the elastic body 62 is elastically deformed, the elastic body 62 tries to elastically return, so that the restoring force (urging force) acts on the sphere 63. As a result, the sphere 63 pushes down the uneven structure 42. That is, the moving body 40 is given an urging force from the urging portion 60 to the support 20 side.

The alternate long and short dash line portion in FIG. 5 shows the sphere 63 and the elastic body 62 when the sphere 63 is placed on the apex of the convex portion 44. In this state, the elastic body 62 is in the most elastically deformed state, and the moving body 40 receives the largest urging force from the urging portion 60. Due to the rotation of the moving body 40, the urging force increases from the apex of the concave portion 43 to the apex of the convex portion 44 passing through the sphere 63. On the other hand, the urging force decreases from the apex of the convex portion 44 to the apex of the concave portion 43 passing through the sphere 63. That is, when the apex of the convex portion 44 passes through the sphere 63, the urging force changes from increasing to decreasing, and this switching is transmitted to the user via the operating body 50 as a click feeling.

Here, the urging force applied to the moving body 40 by the urging unit 60 is caused by the elastic body 62 and the sphere 63 in each slit 612. That is, the urging unit 60 applies an urging force to the moving body 40 from each of a pair of positions overlapping the outer peripheral portion of the moving body 40 at a position sandwiching the rotation center of the moving body 40. Therefore, the urging force can be applied to the moving body 40 in a well-balanced manner.

Even in a state where the recess 43 is directly below the sphere 63, the sphere 63 may push up the elastic body 62. In this case, the sphere 63 always receives the urging force from the elastic body 62. That is, the moving body 40 is always subjected to the urging force from the urging portion 60 to the support 20 side.

[First electrode and second electrode]
Next, the first electrode 70 and the second electrode 80 will be described in detail. FIG. 6 is a plan view showing the first electrode 70 and the second electrode 80 according to the embodiment. In FIG. 6, the first electrode 70 is provided with dot hatching, and the outer shape of the second electrode 80 is indicated by a broken line. As described above, the first electrode 70 is provided on the main surface of the support 20, and the second electrode 80 is provided on the lower surface of the moving body 40.

As shown in FIG. 6, the first electrode 70 has a ground electrode 71 and at least two sets of a transmitting electrode 72 and a receiving electrode 73.

The ground electrode 71 is an example of a reference potential electrode, and has a first ground electrode 74 (first reference electrode potential) and a second ground electrode 75 (second reference potential electrode). The reference potential electrode may be an electrode having a reference potential other than the ground potential. The first ground electrode 74 is formed in a substantially circular shape. The second ground electrode 75 is formed so as to surround the first ground electrode 74 at a predetermined interval. The region R between the first ground electrode 74 and the second ground electrode 75 is formed in a substantially annular shape. This region R is divided into a first region R1 and a second region R2. The first region R1 is a region on the left side of the region R, and the second region R2 is a region on the right side of the region R. In this way, the first region R1 and the second region R2 have the same area. A part of the ground electrode 71 is arranged at the boundary portion between the first region R1 and the second region R2. Specifically, a part of the second ground electrode 75 is arranged at the upper boundary portion in FIG. In FIG. 6, a part of the first ground electrode 74 is arranged at the lower boundary portion.

Further, in the region R, a plurality of sets of transmission electrodes 72 and reception electrodes 73 are arranged. Specifically, the transmission conductive pattern 77 forming each set of transmission electrodes 72 is arranged along the outer circumference of the first ground electrode 74 in the region R. In the transmission conductive pattern 77, a plurality of transmission electrodes 72 are arranged radially along the circumferential direction. Each transmission electrode 72 is formed in a rod shape extending outward. Hereinafter, among the plurality of transmission electrodes 72, the transmission electrode 72 arranged in the first region R1 is referred to as the first transmission electrode 721, and the transmission electrode 72 arranged in the second region R2 is referred to as the second transmission electrode 722. There is.

The plurality of first transmission electrodes 721 are arranged at regular intervals H in the circumferential direction. Similarly, the plurality of second transmitting electrodes 722 are also arranged at regular intervals H in the circumferential direction, but the second transmitting electrode 722 is out of phase with the first transmitting electrode 721. For example, it is assumed that the plurality of first transmission electrodes 721 are arranged at equal intervals in the circumferential direction starting from a position shifted to the left by an angle α with respect to the upper boundary portion. On the other hand, the plurality of second transmission electrodes 722 are arranged at equal intervals in the circumferential direction with respect to the upper boundary portion in the right direction and starting from a position deviated by an angle β larger than the angle α.

A pair of receiving

conductive patterns

781 and 782 forming each set of receiving electrodes 73 are arranged along the inner circumference of the second ground electrode 75 in the region R. Of the pair of receive

conductive patterns

781 and 782, one of the received conductive patterns 781 is arranged in the first region R1, and the other received conductive pattern 782 is arranged in the second region R2. In one receiving conductive pattern 781 and the other receiving conductive pattern 782, a plurality of receiving electrodes 73 are arranged radially along the circumferential direction. Each receiving electrode 73 is formed in a rod shape extending inward.

Hereinafter, among the plurality of receiving electrodes 73, the receiving electrode 73 arranged in the first region R1 is referred to as the first receiving electrode 731, and the receiving electrode 73 arranged in the second region R2 is referred to as the second receiving electrode 732. There is. In the present embodiment, 14 sets of the first transmitting electrode 721 and the first receiving electrode 731 are provided in the first region R1, and 14 sets of the second transmitting electrode 722 and the second receiving electrode 732 are provided in the second region R2. There are sets.

Each first receiving electrode 731 faces a pair of first transmitting electrodes 721 at regular intervals W in the circumferential direction. Each second receiving electrode 732 faces the paired second transmitting electrode 722 at a constant interval W in the circumferential direction. As described above, since the first transmitting electrode 721 and the second transmitting electrode 722 have different phases, the first receiving electrode 731 and the second receiving electrode 732 also have different phases. In this embodiment, the case where the transmitting electrode 72 is arranged inside and the receiving electrode 73 is arranged outside is illustrated, but the positional relationship between the transmitting electrode and the receiving electrode may be reversed.

The second electrode 80 has a circular portion 81, an outer ring portion 82, and a plurality of connecting portions 83. The circular portion 81 is a circular portion and substantially overlaps with the first ground electrode 74 in a plan view. The outer ring portion 82 is a portion concentric with the circular portion 81 that surrounds the circular portion 81 over the entire circumference at a predetermined interval. The outer ring portion 82 substantially overlaps with the second ground electrode 75 in a plan view. 32 of the plurality of connecting portions 83 are provided in the present embodiment. The plurality of connecting portions 83 are arranged between the circular portion 81 and the outer ring portion 82, and are arranged at equal intervals along the circumferential direction. Specifically, the connecting portions 83 are arranged at intervals H in the circumferential direction. Each connecting portion 83 has a rod shape along the radial direction, and is connected to the circular portion 81 and the outer ring portion 82.

The second electrode 80 rotates as the moving body 40 rotates. At this time, the second electrode 80 rotates with a predetermined distance from the first electrode 70. During rotation, each connecting portion 83 repeatedly approaches or retreats from each transmitting electrode 72 and receiving electrode 73 in the circumferential direction. At this time, each connecting portion 83 arranged in the first region R1 has a uniform positional relationship with respect to each pair of the first transmitting electrode 721 and the first receiving electrode 731. Each connecting portion 83 arranged in the second region R2 has a uniform positional relationship with respect to each set of the second transmitting electrode 722 and the second receiving electrode 732. However, as described above, the phases of the first transmitting electrode 721 and the first receiving electrode 731 and the second transmitting electrode 722 and the second receiving electrode 732 are different from each other. Therefore, the phases of the connecting portions 83 when approaching or moving away from them are also different.

FIG. 7 is a schematic view of the positional relationship between the first electrode 70 and the second electrode 80 according to the embodiment as viewed from the side. In FIG. 7, a set of the first transmitting electrode 721 and the first receiving electrode 731 of the first electrode 70 are collectively illustrated, and a set of the second transmitting electrode 722 and the second receiving electrode 732 are collectively illustrated. ing.

(A) of FIG. 7 shows the first state. The first state includes the area where the first transmitting electrode 721 and the first receiving electrode 731 overlap with the connecting portion 83 of the second electrode 80 (superimposed area S1), and the second transmitting electrode 722 and the second receiving electrode 732. Is a state in which the area overlapped with the connecting portion 83 (superimposed area S2) is equal. Here, the transmitting electrode 72 and the receiving electrode 73 of each set are arranged apart from each other in the circumferential direction, but the region between them is also a region forming the transmitting electrode 72 and the receiving electrode 73. Therefore, when the region also overlaps with the connecting portion 83, it is included in the overlapping areas S1 and S2.

(B) in FIG. 7 shows the second state. The second state is a distance L1 in which the first transmitting electrode 721 and the first receiving electrode 731 are separated from the connecting portion 83, and a distance L2 in which the second transmitting electrode 722 and the second receiving electrode 732 are separated from the connecting portion 83. It is a state of equalization. In addition, "equal" is not only completely the same, but also includes those containing a slight difference of about several percent. That is, it may be substantially equal. This is the same even if it is equivalent.

The second electrode 80 rotates relative to the first electrode 70. Therefore, the transition from the first state to the second state and the transition from the second state to the first state are repeatedly performed. Further, during rotation, the circular portion 81 of the second electrode 80 always faces the first ground electrode 74, and the outer ring portion 82 of the second electrode 80 also faces the second ground electrode 75. Always facing each other. Therefore, even while the second electrode 80 is rotating, the electrical coupling between the circular portion 81 and the first ground electrode 74 becomes strong, and the electrical coupling between the outer ring portion 82 and the second ground electrode 75 Becomes stronger.

Here, the electric capacity between the transmitting electrode 72 and the receiving electrode 73 and the connecting portion 83 becomes smaller when the superposed area is the largest. On the contrary, when the transmitting electrode 72 and the receiving electrode 73 and the connecting portion 83 are farthest apart, the electric capacity becomes large. From each receiving electrode 73, the amount of change in the electric capacity at that time is output as an electric signal.

[Control configuration]
Next, the control configuration of the input device 10 will be described. FIG. 8 is a block diagram showing a control configuration of the input device 10 according to the embodiment. As shown in FIG. 8, the input device 10 includes a first electrode 70, a touch sensor 200, and a control unit 90 electrically connected to the display panel 300. The control unit 90 includes a CPU, a RAM, and a ROM, and the CPU expands a program stored in the ROM into the RAM and executes the program to execute various processes. The control unit 90 applies electric power to the transmitting electrode 72 of the first electrode 70, and detects the relative movement amount of the second electrode 80 with respect to the first electrode 70 based on the electric signal received from the receiving electrode 73. To do. The detection of the movement amount will be described later. The control unit 90 also receives the input signal from the touch sensor 200, and controls the display content of the display panel 300 based on the input signal and the detected movement amount.

For example, the control unit 90 controls the emission color of the pixel group overlapping the support 20 on the display panel 300. As a result, the display panel 300 irradiates the support 20 with light. As described above, each member of the input device 10 (support 20, fixed body 30, moving body 40, operating body 50, urging portion 60, first electrode 70, and second electrode 80) has translucency. Therefore, the light emitted from the display panel 300 guides each member. Therefore, the light from the display panel 300 can give an optical effect to each member.

[Detection of movement amount]
Next, the detection of the movement amount will be described. FIG. 9 is an explanatory diagram for explaining the detection of the movement amount of the input device 10 according to the embodiment. FIG. 9A shows a change in capacitance between the first electrode 70 and the second electrode 80 during rotation. Specifically, the capacitance change formed by the first transmitting electrode 721 and the first receiving electrode 731 and the connecting portion 83 is defined as the first capacitance change Q1, and the second transmitting electrode 722, the second receiving electrode 732, and the connecting portion 83 are connected to each other. The capacity change to be made is referred to as the second capacity change Q2. The first capacitance change Q1 and the second capacitance change Q2 have waveforms having different phases from each other. At the point P11 of the first capacitance change Q1, the overlapping area between the first transmitting electrode 721 and the first receiving electrode 731 and the connecting portion 83 is the largest, and at the point P12, the first transmitting electrode 721 and the first receiving electrode The distance between the 731 and the connecting portion 83 is the largest. Similarly, at the point P21 of the first capacitance change Q1, the overlapping area between the second transmitting electrode 722 and the second receiving electrode 732 and the connecting portion 83 is the largest, and at the point P22, the second transmitting electrode 722 and the second transmitting electrode 722 and the second (Ii) The distance between the receiving electrode 732 and the connecting portion 83 is the largest.

Here, in FIG. 9A, the point P10 is set as the mechanical operation origin of the input device 10. The point P10 is a location corresponding to the second state, and is near the intersection of the first capacitance change Q1 and the second capacitance change Q2. At point P10, at least one of the first capacitance change Q1 and the second capacitance change Q2 may be calibrated so that the first capacitance change Q1 and the second capacitance change Q2 intersect.

(B) of FIG. 9 shows the change in the electrical state during rotation. Here, the electrical state is the amount of change of the first capacitance change Q1 and the second capacitance change Q2, respectively. This amount of change is detected as an electric signal in the control unit 90. In FIG. 9B, the waveform of the capacitance change rate (Δc / c) of the first capacitance change Q1 is the first waveform W1, and the waveform of the capacitance change rate of the second capacitance change Q2 is the second waveform W2. The control unit 90 distinguishes a portion of each of the first waveform W1 and the second waveform W2 as an ON signal and a portion below a predetermined threshold value as an OFF signal. The distinction result is shown in FIG. 9 (c). In FIG. 9C, the distinction result T1 for the first waveform W1 and the distinction result T2 for the second waveform W2 are shown.

At the operating origin (point P10), each of the first waveform W1 and the second waveform W2 is generated on the negative side with respect to a predetermined threshold value, so that the distinction results T1 and T2 are also OFF signals at the operating origin. It is common in. If the point P19 is set as the operating origin, the ON signal and the OFF signal are mixed at the operating origin, which is not preferable.

The control unit 90 sets the portion where each of the first waveform W1 and the second waveform W2 becomes an ON signal as the movement amount per unit. In the present embodiment, the movement amount per unit is the movement amount for one click.

Further, the control unit 90 determines that the case where the first waveform W1 outputs the ON signal first and the second waveform W2 outputs the ON signal later within the movement amount per unit is "normal rotation". The case where the second waveform W2 outputs the ON signal first and the first waveform W1 outputs the ON signal later is determined to be "reversal".

In the present embodiment, the case where the location corresponding to the second state is the operating origin is illustrated, but the location corresponding to the first state may be the operating origin. In this case, the control unit 90 may invert the first waveform and the second waveform according to their respective positive and negative values to distinguish between an ON signal and an OFF signal.

[Effects, etc.]
As described above, the input device 10 according to the present embodiment includes the first electrode 70, the support 20 that supports the first electrode 70, the fixed body 30 fixed to the support 20, and the second electrode 80. A moving body that moves the second electrode 80 closer to or further away from the first electrode 70 by holding the second electrode 80 in a state of facing the first electrode 70 at a predetermined interval and rotating the second electrode 80. The operating body 50 is held in the fixed body 30 so as to be relatively movable with respect to the fixed body 30 while being engaged with the moving body 40, and the moving body 40 is rotated by being operated by the user. The moving body 40 has an operating body 50 and an urging portion 60 which is arranged between the moving body 40 and the fixed body 30 and imparts an urging force to the support 20 side to the moving body 40. A concavo-convex structure 42 in which a plurality of recesses 43 recessed in a direction orthogonal to the moving direction in which the moving body 40 moves and a plurality of convex portions 44 protruding in the direction are continuously and alternately arranged along the moving direction. The urging portion 60 is arranged between the elastic body 62 for applying the urging force and the concave-convex structure 42 and the elastic body 62, and elasticizes the elastic body 62 in conjunction with the movement of the moving body 40. It has a sphere 63 to be deformed and a holding body 61 fixed to the fixed body 30 and holding the elastic body 62 and the sphere 63 in a variable manner, and operates the support 20, the fixed body 30, and the moving body 40. The body 50, the elastic body 62, the sphere 63, and the holding body 61 have translucency.

According to this, since the elastic body 62, the sphere 63, and the holding body 61, which are structures for giving a click feeling to the operating body 50, have translucency, a metal click spring is not used. However, it is possible to enhance the translucency inside the input device 10 while realizing a click feeling.

In particular, since the support 20, the fixed body 30, the moving body 40, the operating body 50, the elastic body 62, the sphere 63, and the holding body 61 forming the input device 10 have translucency. , The input device 10 as a whole enables an optical effect.

Further, the uneven structure 42 is arranged closer to the support 20 than the holding body 61, and the sphere 63 and the elastic body 62 are arranged in this order on the uneven structure 42.

According to this, since the sphere 63 and the elastic body 62 are arranged in this order on the concave-convex structure 42, the urging force toward the support 20 caused by the elastic body 62 is applied to the sphere 63 and the concave-convex structure 42. It can be imparted to the moving body 40 via. Therefore, the urging force toward the support 20 can be reliably applied to the moving body 40.

Further, the sphere 63 moves up and down in conjunction with the moving uneven structure 42. When the sphere 63 is irradiated with light, it may be diffusely reflected by the ascending / descending motion to cause flicker. In the present embodiment, since the elastic body 62 is arranged outside the sphere 63, the flicker caused by the sphere 63 is less noticeable. As a result, the optical effect can be enhanced.

Further, the pressing body that elastically deforms the elastic body 62 in conjunction with the movement of the moving body 40 is the sphere 63. According to this, since the pressing body is the sphere 63, the sphere 63 can be smoothly moved on the uneven structure 42, and smooth operability can be realized.

Further, the input device 10 first sets the first electrode 70, the support 20 that supports the first electrode 70, the fixed body 30 fixed to the support 20, the second electrode 80, and the second electrode 80. The moving body 40 and the moving body 40 move the second electrode 80 closer to or farther from the first electrode 70 in the moving direction by holding the electrode 70 in a state of facing each other at a predetermined distance and rotating the electrode 70. An operating body 50 that is held so as to be relatively movable with respect to the fixed body 30 in an engaged state, and the operating body 50 that rotates the moving body 40 by being operated by the user, and the moving body 40 and the fixed body. It has an urging portion 60, which is arranged between the 30 and 30 and applies an urging force toward the support 20 to the moving body 40.

According to this, since the urging unit 60 applies the urging force toward the support 20 to the moving body 40, the first electrode 70 supported by the support 20 is held by the moving body 40. It can be pressed toward the electrode 80. As a result, even when the moving body 40 is moving, the second electrode 80 is pressed against the first electrode 70, and the distance between them is kept constant. Therefore, the change in the electrical state between the first electrode 70 and the second electrode 80 can be reliably detected. Therefore, the sensitivity of changes in the electrical state of the input device 10 can be maintained.

Further, the moving body 40 is independently given the acting force given by the operating body 50 and the urging force given by the urging unit 60 at the time of movement.

According to this, since the acting force given by the operating body 50 and the urging force given by the urging unit 60 at the time of movement are independently applied to the moving body 40, the acting force and the urging force can be obtained. It can act on different locations on the moving body 40. Therefore, the moving body 40 can be moved smoothly. Since the moving body 40 moves smoothly, friction with respect to the first electrode 70 and the second electrode 80 can also be suppressed.

Further, in the moving body 40, a plurality of recesses 43 recessed in a direction orthogonal to the moving direction in which the moving body 40 moves and a plurality of convex portions 44 protruding in the direction are continuously and alternately alternately arranged along the moving direction. The concavo-convex structure 42 is arranged, and the urging portion 60 is arranged between the elastic body 62 for applying the urging force and the concavo-convex structure 42 and the elastic body 62, and is linked to the movement of the moving body 40. It has a sphere 63 that elastically deforms the elastic body 62, and a holding body 61 that is fixed to the fixed body 30 and holds the elastic body 62 and the sphere 63 in a variable manner.

Here, due to the movement of the moving body 40, the urging force received from the elastic body 62 increases from the apex of the concave portion 43 of the concave-convex structure 42 to the apex of the convex portion 44 passing through the sphere 63. On the other hand, the urging force received from the elastic body 62 decreases from the apex of the convex portion 44 to the apex of the concave portion 43 passing through the sphere 63. That is, when the apex of the convex portion 44 passes through the sphere 63, the urging force changes from an increase to a decrease, so that this switching can be transmitted to the user as a click feeling.

Further, the holding body 61 is formed with a concave relief portion 64 that receives elastic deformation of the elastic body 62, and the relief portion 64 is on the side opposite to the sphere 63 with respect to the elastic body 62 in the holding body 61. It is formed in the site.

According to this, since the holding body 61 is provided with a concave relief portion 64 that receives elastic deformation of the elastic body 62, the internal space of the relief portion 64 is a space for the elastic body 62 to escape. Therefore, elastic deformation of the elastic body 62 can be promoted, and even a thin elastic body 62 can be smoothly elastically deformed and elastically restored. Therefore, the elastic body 62 can be made thin.

Further, the moving body 40 and the operating body 50 rotate around the center of rotation, and the urging portion 60 sandwiches the center of rotation of the moving body 40 and moves from a pair of positions overlapping the outer peripheral portion of the moving body 40. Gives urging power to 40.

According to this, the pair of urging portions 60 are positioned to sandwich the rotation center of the moving body 40, and urging force is applied to the moving body 40 from the pair of positions overlapping the outer peripheral portion of the moving body 40. Therefore, it is possible to give a well-balanced urging force to the moving body 40. Therefore, the second electrode 80 can be stably pressed against the first electrode 70.

Further, the input device 10 according to the present embodiment is in a state where the ground electrode 71 and the first electrode 70 having at least two sets of the transmitting electrode 72 and the receiving electrode 73 face the first electrode 70 at a predetermined interval. The ground electrode 71 is provided with two or more sets of transmitting electrodes and a second electrode 80 that moves the transmitting electrode 72 and the receiving electrode 73 closer to or further away from each other in the moving direction by rotating. Of the 72 and the receiving electrode 73, as a result of the second electrode 80 approaching at least one set of the transmitting electrode 72 and the receiving electrode 73, the second electrode 80 faces at least a part of the second electrode 80, and two or more sets of transmitting electrodes are transmitted. The electrodes 72 and the receiving electrode 73 include a first set of transmitting electrodes 72 and receiving electrodes 73 arranged in the first region R1 and a second set of transmitting electrodes 72 and receiving electrodes 73 arranged in the second region R2. Including, the phase when the first set of the first transmitting electrode 721 and the first receiving electrode 731 approaches or moves away from the second electrode 80 is such that the second set of the second transmitting electrode 722 and the second receiving electrode 732 are included. , It is different from the phase when approaching or moving away from the second electrode 80.

According to this, the second electrode 80 moves with respect to at least two sets of the transmitting electrode 72 and the receiving electrode 73 by rotating in a state of facing the first electrode 70 at a predetermined interval. Approach or move away in the direction. Therefore, during rotation, the electrical state between the first electrode 70 and the second electrode 80 changes. By detecting this change in the electrical state, it is possible to detect the relative movement amount between the first electrode 70 and the second electrode 80 even without the third electrode. Since the first electrode 70 and the second electrode 80 face each other with a predetermined interval even during relative movement, friction does not occur. Therefore, damage to the first electrode 70 and the second electrode 80 can be suppressed, and the quality can be maintained for a long period of time.

Further, the first set of the first transmitting electrode 721 and the first receiving electrode 731 arranged in the first region R1 and the second set of the second transmitting electrode 722 and the second receiving electrode 732 arranged in the second region R2. However, the phases when approaching or moving away from the second electrode 80 are different. Therefore, the phase is different from the change in the electric state caused by the set arranged in the first region R1 and the change in the electric state caused by the set arranged in the second region R2. By detecting this phase difference, it is possible to detect the direction of rotational movement.

Further, one or more reference potential electrodes are ground electrodes 71.

According to this, since the reference potential electrode is the ground electrode 71, it is not necessary to add a power supply, and the circuit configuration can be simplified.

Further, the operating origins of the input device 10 are a superposed area S1 in which the first set of the first transmitting electrode 721 and the first receiving electrode 731 overlap the second electrode 80, and the second set of the second transmitting electrode 722 and the second. This is a state (first state) in which the superposed area S2 on which the receiving electrode 732 overlaps the second electrode 80 is substantially equal.

Alternatively, the operating origin of the input device 10 is a distance L1 in which the first set of first transmitting electrode 721 and the first receiving electrode 731 are separated from the second electrode 80, and the second set of second transmitting electrodes 722 and second. This is a state (second state) in which the receiving electrode 732 is substantially equal to the distance L2 away from the second electrode 80.

According to this, since the operating origin of the input device 10 is the first state or the second state, the change in the electrical state caused by the set arranged in the first region R1 and the change in the electrical state are arranged in the second region R2. The origin of operation is near the intersection with the change in electrical state caused by the set. As a result, at the origin of operation, the change in the electrical state caused by the set arranged in the first region R1 and the change in the electrical state caused by the set arranged in the second region R2 are generated. Since it occurs on the same side of the positive side or the negative side with respect to a predetermined threshold value, these distinction results are also shared between the ON signal and the OFF signal at the operating origin. Thereby, it is possible to more accurately detect the relative movement amount between the first electrode 70 and the second electrode 80. Therefore, the quality of the input device 10 can be improved without using the third electrode.

Further, the area of the first region R1 and the area of the second region R2 are substantially the same.

As a result, the change in the electrical state caused by the set arranged in the first region R1 and the change in the electrical state caused by the set arranged in the second region R2 can be made equal. The phase difference of these changes in the electrical state can be detected more reliably. Therefore, the quality of the input device 10 can be improved without using the third electrode.

Further, at least two sets of the transmitting electrode 72 and the receiving electrode 73 are arranged side by side along the ring, and one or more ground electrodes 71 are arranged with the first ground electrode 74 arranged inside the ring. , A second ground electrode 75 arranged on the outer side of the ring.

According to this, since the ground electrode 71 has the first ground electrode 74 and the second ground electrode 75, the electrical coupling of the ground potential can be strengthened, and the electrical state of the first electrode 70 can be increased. The change can be large. If the change in the electrical state of the first electrode 70 can be made large, the detection accuracy can be improved.

Further, the first electrode 70 and the second electrode 80 are transparent electrodes.

According to this, since the first electrode 70 and the second electrode 80 are transparent electrodes, the information on the back side of the input device 10 can be transmitted through the first electrode 70 and the second electrode 80. Therefore, it is possible to realize an input device 10 having a high design.

Further, the first electrode 70 is an electrode of the touch sensor 200.

According to this, since the electrode of the touch sensor 200 is used as the first electrode 70, when the input device 10 is installed on the touch sensor 200, the electrode of the touch sensor 200 and the first electrode 70 of the input device 10 are separated. Can also be used. Therefore, it is possible to reduce the number of parts.

Further, the input device 10 further includes an electrical shielding layer 400 arranged on the opposite side of the second electrode 80 in the first electrode 70.

According to this, since the electrical shielding layer 400 is arranged on the side of the first electrode 70 opposite to the second electrode 80, the noise from the electrical equipment arranged on the back side of the input device 10 is blocked by the shielding layer 400. Can be blocked with. Therefore, it is possible to more accurately detect the relative movement amount between the first electrode 70 and the second electrode 80.

Further, the input device 10 holds and supports the display panel 300 (image display unit), the translucent support 20 which is arranged on the display panel 300 and supports the first electrode 70, and the second electrode 80. A translucent moving body 40 that rotates and moves with respect to the body 20 is provided, and the display panel 300 irradiates at least one of the support 20 and the moving body 40 with light, and irradiates the light to the support 20 and the moving body 40. Guide light to at least one of the bodies 40.

According to this, the display panel 300 irradiates at least one of the support 20 and the moving body 40 with light, and guides the light to at least one of the support 20 and the moving body 40. On the other hand, an optical effect can be applied.

Further, since a part of the ground electrode 71 is arranged at the boundary portion between the first region R1 and the second region R2, electrical interference between the first region R1 and the second region R2 is unlikely to occur. Become. As a result, it is possible to accurately detect the change in the electrical state between the first transmitting electrode 721 and the first receiving electrode 731 and the change in the electrical state between the second transmitting electrode 722 and the second receiving electrode 732. It becomes.

[Modification example]
Next, a modified example will be described. In the following description, the same parts as those in the above embodiment may be designated by the same reference numerals and the description thereof may be omitted. FIG. 10 is an explanatory diagram schematically showing a layout example of the first electrode according to the present disclosure.

This layout is called the first layout.

In FIG. 10B, the first region R1b and the second region R2b of the first electrode 70B form concentric circles. This layout is called the second layout.

Specifically, in the second electrode 80C1, the number of connecting portions 83 installed is halved as compared with the second electrode 80 according to the embodiment. Specifically, the number of connected portions 83 of the second electrode 80C1 is 16. Therefore, the distance between the connecting portions 83 of the second electrode 80C1 in the circumferential direction is wider than that of the second electrode 80 according to the embodiment.

The first electrode 70C1 has a ground electrode 71c1 and at least two sets of transmitting electrodes 72c1 and receiving electrodes 73c1.

The ground electrode 71c1 has a first ground electrode 74c1 and a second ground electrode 75c1. The first ground electrode 74c1 is formed in a substantially circular shape. The annular region surrounding the first ground electrode 74c1 is the region Rc. This region Rc is divided into a first region R1c and a second region R2c. Further, the first region R1c is evenly divided into two in the circumferential direction, and is divided into a first division region c11 and a second division region c12. The second region R2c is evenly divided into two in the circumferential direction, and is divided into a third division region c23 and a fourth division region c24.

Further, the second ground electrode 75c1 includes a plurality of divided ground electrodes. The plurality of divided ground electrodes are the first divided ground electrode 76c1, the second divided ground electrode 77c1, the third divided ground electrode 78c1, and the fourth divided ground electrode 79c1.

The first division ground electrode 76c1 is partially extended so as to overlap the outer ring portion 82 of the second electrode 80C1 in a plan view, and the tip portion thereof is a boundary between the first division region c11 and the second division region c12. It is located in.

The second divided ground electrode 77c1 is partially extended so as to overlap the outer ring portion 82 of the second electrode 80C1 in a plan view, and its tip portion is a boundary between the third divided region c23 and the fourth divided region c24. It is located in.

The tip of the fourth division ground electrode 79c1 is arranged at the boundary between the second division region c12 and the fourth division region c24.

As described above, since a part of the ground electrode 71c1 is arranged at each boundary portion, electrical interference is less likely to occur between the divided regions.

Further, a plurality of sets of transmission electrodes 72c1 and reception electrodes 73c1 are arranged in the region Rc. Specifically, the transmission conductive pattern 77c forming each set of transmission electrodes 72c1 is arranged along the outer circumference of the first ground electrode 74c1 in the region Rc. In the transmission conductive pattern 77c, a plurality of transmission electrodes 72c1 are radially arranged along the circumferential direction. Each transmission electrode 72c1 is formed in a rod shape extending outward.

Within each divided region, three sets of transmitting electrodes 72c1 and three sets of receiving electrodes 73c1 are provided. As compared with the above embodiment, since the transmitting electrode 72c1 and the receiving electrode 73c1 are thinned out, the distance between the sets in the circumferential direction is widened. Further, in each divided region, a plurality of sets of transmitting electrodes 72c1 and receiving electrodes 73c1 are arranged so as to have different phases in the circumferential direction from a plurality of sets of transmitting electrodes 72c1 and receiving electrodes 73c1 in other divided regions. .. Therefore, a phase difference occurs in the capacitance change between the transmitting electrode 72c1 and the receiving electrode 73c1 and the connecting portion 83 of the second electrode 80C1 in each divided region during rotation.

FIG. 15 is an explanatory diagram for explaining the detection of the movement amount of the input device according to the modified example 4. FIG. 15A shows the capacitance change between the first electrode 70C1 and the second electrode 80C1 during rotational movement. Specifically, the capacitance change formed by the plurality of sets of transmission electrodes 72c1 and reception electrode 73c1 and the connecting portion 83 in the first partition region c11 is referred to as the first capacitance change Q11. The capacitance change between the plurality of sets of transmission electrodes 72c1 and reception electrode 73c1 and the connecting portion 83 in the second division region c12 is referred to as the second capacitance change Q12.

Points P20 and P30 are locations corresponding to the second state, are near the intersection of the first capacitance change Q11 and the third capacitance change Q13, and are the intersections of the second capacitance change Q12 and the fourth capacitance change 14. It is in the vicinity.

(B) of FIG. 15 shows the change in the electrical state during rotation. Here, the electrical state is the amount of change of each of the first capacitance change Q11 to the fourth capacitance change Q14. This amount of change is input to the control unit 90 as an electric signal. In FIG. 15B, the waveform of the capacitance change rate of the first capacitance change Q11 is the first waveform W11, the waveform of the capacitance change rate of the second capacitance change Q12 is the second waveform W12, and the waveform of the third capacitance change Q13. The waveform of the capacitance change rate is the third waveform W13, and the waveform of the capacitance change rate of the fourth capacitance change Q14 is the fourth waveform W14. As described above, as compared with the above-described embodiment, the interval in the circumferential direction of each set is widened, so that the amount of change can be increased. As a result, the accuracy of position detection is improved.

The control unit 90 distinguishes each of the first waveform W11 to the fourth waveform W14 as an ON signal for a portion above a predetermined threshold value and an OFF signal for a portion below the predetermined threshold value. The distinction result is shown in FIG. 15 (c). FIG. 15 (c) shows the distinction result T11 for the first waveform W11, the distinction result T12 for the second waveform W12, the distinction result T13 for the third waveform W13, and the distinction result T14 for the fourth waveform W14. There is.

At the operating origin (point P20), each of the first waveform W11 to the fourth waveform W14 is generated on the negative side with respect to a predetermined threshold value, so that the distinction results T11 to T14 are also OFF signals at the point P20. It is common in. The control unit 90 sets the portion where each of the first waveform W11 and the third waveform W13 is an ON signal as the movement amount per unit. In the present embodiment, the movement amount per unit is the movement amount for one click.

At the operating origin (point P30), each of the first waveform W11 to the fourth waveform W14 is generated on the negative side with respect to a predetermined threshold value, so that the distinction results T11 to T14 are also OFF signals at the point P20. It is common in. The control unit 90 sets the portion where each of the second waveform W12 and the fourth waveform W14 is an ON signal as the movement amount for one click.

Even in this case, the control unit 90 can determine "forward rotation" and "reverse rotation" based on the appearance order of each waveform within the movement amount per unit.

On the other hand, the receiving electrode 73c2 has a plurality of tooth portions 735c protruding toward the paired transmitting electrode 72c2. The plurality of tooth portions 725c and the plurality of tooth portions 725c are alternately arranged along the radial direction in a separated state. In this way, since the transmitting electrode 72c2 and the receiving electrode 73c2 have a comb-tooth shape, the distance between the transmitting electrode 72c2 and the receiving electrode 73c2 is increased to increase the sensitivity, but the area is made larger than that in the rod shape to increase the capacity. Can be secured.
