Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the DJ equipment described in Non-Patent Document 1 above, the platter is rotatably connected to the platter, and it is not easy for the user to remove the platter from the platter. For this reason, it is difficult to adjust the frictional force between the platter and the platter. Regarding such a problem, since the preference for the frictional force between the platter and the platter, that is, the preference for the operating feeling of the platter is likely to be divided, a configuration capable of adjusting the frictional force has been demanded.

Means for Solving the Problems

[0005] The rotary operator according to the first aspect of the present invention includes a first rotating body that can rotate about a virtual rotation axis, a second rotating body that is detachably provided and that rotates integrally with the first rotating body and can rotate about the rotation axis individually from the first rotating body, and a friction adjusting member that is covered by the second rotating body when viewed from the second rotating body side with respect to the first rotating body and that adjusts the frictional force between the first rotating body and the second rotating body. The first rotating body has an arrangement portion where the friction adjusting member is detachably arranged and a first engaging portion. The second rotating body has a second engaging portion with which the first engaging portion can engage.

[0006] The operating device according to the second aspect of the present invention includes the rotary operator according to the first aspect.

[0007] The acoustic control device according to the third aspect of the present invention includes the operating device according to the second aspect.

MODE FOR CARRYING OUT THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [External Configuration of Acoustic Control Device] FIG. 1 is a plan view showing an acoustic control device 1 according to the present embodiment. In FIG. 1, for ease of viewing, reference numerals are attached only to a part of a plurality of buttons BT, a part of a plurality of levers LV, a part of a plurality of sliders SL, and a part of a plurality of dials DL included in the acoustic control device 1. As shown in FIG. 1, the acoustic control device 1 according to the present embodiment includes a housing 11, a plurality of operators 12 provided on the housing 11, and a control unit (not shown) provided inside the housing 11. The control unit outputs an operation signal for adjusting the playback state of the input music according to the user's operations on the plurality of operators 12, or outputs an audio signal of the music whose playback state has been adjusted. That is, the audio control device 1 has a function as an operation device that transmits an operation signal corresponding to the user's operation on the operator 12 to a music playback device (not shown) connected to the audio control device 1. In other words, the audio control device 1 includes an operation device having a rotary operator 2 described later. Alternatively, the audio control device 1 has a function as a music playback device that transmits an audio signal of the music played in response to an operation on the operator 12 to an audio output device (not shown) such as a speaker connected to the audio control device 1.

[0010] [Configuration of Operators] The plurality of operators 12 are operating means provided on the top surface 11A of the housing 11 facing the user. The plurality of operators 12 include two rotary operators 2, a plurality of buttons BT, a plurality of levers LV, a plurality of sliders SL, and a plurality of dials DL. When each operator 12 is operated by the user, it outputs an operation signal corresponding to the operation state to the control unit.

[0011] [Configuration of Rotary Operator] FIG. 2 is a perspective view of the rotary operator 2 viewed from the top surface side, and FIG. 3 is a perspective view of the rotary operator 2 viewed from the bottom surface side. Also, FIG. 4 is an exploded perspective view of the rotary operator 2 viewed from the top surface side, and FIG. 3 is an exploded perspective view of the rotary operator 2 viewed from the bottom surface side. As shown in FIGS. 2 to 4, the rotary operator 2 includes an operator body 3 and a second rotating body 9. The operator body 3 has a base member 4, a first rotating body 5, a plate 6, a display unit 7, and a friction adjustment member 8. The rotary operator 2 is a jog dial in which the first rotating body 5 and the second rotating body 9 rotate about the rotation axis Rx when the rotary operator 2 is in use, that is, a so-called motorized jog dial.

[0012] In the following description, three mutually orthogonal directions are defined as the +X direction, +Y direction, and +Z direction. The +Z direction is, for example, the direction from the bottom surface to the top surface of the housing 11. The +Z direction is the direction toward the second rotating body 9 with respect to the first rotating body 5 described later. When the upward direction as viewed from the +Z direction coincides with the +Y direction, the right direction is the +X direction. Although not shown, the opposite direction of the +X direction is the -X direction, the opposite direction of the +Y direction is the -Y direction, and the opposite direction of the +Z direction is the -Z direction. That is, on the top surface side of the rotation operator 2 is the +Z direction, and on the bottom surface side is the -Z direction. In the rotation operator 2, the base member 4, the first rotating body 5, the plate 6, the display unit 7, the friction adjustment member 8, and the second rotating body 9 are arranged in the +Z direction.

[0013] [Configuration of the base member] FIG. 6 is a perspective view of the base member 4 and the first rotating body 5 as viewed from the +Z direction. The base member 4 is fixed inside the housing 11 and rotatably supports the first rotating body 5 and the second rotating body 9 about the virtual rotation axis Rx, and also supports the display unit 7. As shown in FIGS. 5 and 6, the base member 4 includes a housing portion 41, a shaft portion 42, a first detection unit 43, and a drive device 44.

[0014] The housing portion 41 is formed in a disk shape and constitutes the exterior of the rotation operator 2 in the -Z direction. The housing portion 41 has a recess 411 that opens in the +Z direction. The recess 411 is recessed from the +Z direction surface toward the -Z direction and is formed in a substantially circular shape as viewed from the +Z direction. Inside the recess 411, the shaft portion 42, the first detection unit 43, and the drive device 44 are arranged.

[0015] The shaft portion 42 stands upright in a substantially cylindrical shape in the +Z direction from a position substantially at the center of the recess 411. The shaft portion 42 rotatably supports the first rotating body 5 and the second rotating body 9 and supports the display unit 7 so as not to rotate. That is, the shaft portion 42 constitutes the rotation axis Rx of the first rotating body 5 and the second rotating body 9. The extension line of the central axis of the shaft portion 42 along the +Z direction coincides with the rotation axis Rx. The shaft portion 42 has a through hole 421 that penetrates the shaft portion 42 in the +Z direction. A cable CA connected to the display unit 7 is inserted into the through hole 421. That is, one end of the cable CA is connected to the display unit 7 fixed to the shaft portion 42, and the other end extends outside the rotary operator 2 by inserting through the through hole 421 in the -Z direction.

[0016] The first detection unit 43 is disposed on the inner surface of the recess 411. The first detection unit 43 detects the rotation state of the first rotating body 5. Specifically, the first detection unit 43 detects the rotation direction and rotation speed of the first rotating body 5. The rotation state of the first rotating body 5 detected by the first detection unit 43 is output to the above-described control unit. In the present embodiment, the first detection unit 43 has a photo interrupter that detects the light passing through the slit provided in the rotation detection disk 53 (see FIG. 7) of the first rotating body 5 to detect the rotation state of the first rotating body 5. However, as long as the first detection unit 43 can detect the rotation state of the first rotating body 5, other configurations may be used.

[0017] The drive device 44 is provided at the bottom of the recess 411 and rotates the first rotating body 5 under the control of the control unit. That is, the rotary operator 2 includes a drive device 44 that rotates the first rotating body 5. In the present embodiment, the drive device 44 has a coil 441 and a substrate 442. A plurality of coils 441 are provided around the shaft portion 42. The substrate 442 is provided in the recess 411 so as to cover the plurality of coils 441 in the +Z direction. Although detailed illustration is omitted, the substrate 442 supports the plurality of coils 441 and circuit elements such as Hall elements. The substrate 442 is formed in a ring shape when viewed from the +Z direction. The substrate 442 has an opening 443 provided at the center of the substrate 442 when viewed from the +Z direction. The shaft portion 42 is inserted through the opening 443 along the +Z direction and is exposed to the substrate 442 in the +Z direction. However, the configuration of the drive device 44 is not limited to such a configuration, and any configuration may be used as long as the first rotating body 5 can rotate about the rotation axis Rx.

[0018] [Configuration of the first rotating body] FIG. 7 is a perspective view of the first rotating body 5 as viewed from the -Z direction. FIG. 8 is a view showing a cross section of the base member 4 and the first rotating body 5 along the XZ plane. The first rotating body 5 is a so-called platter that is rotatably attached to the shaft portion 42 via bearings BR1 and BR2 about the rotation axis Rx. The first rotating body 5 is arranged to cover the base member 4 in the +Z direction as shown in FIGS. 3 to 5. The first rotating body 5 includes a main body portion 51 as shown in FIGS. 6 to 8, and also has a cylindrical portion 52, a rotation detection disk 53, a holding member 54, a magnet 55, and an engagement piece 56 as shown in FIGS. 7 and 8.

[0019] The main body portion 51 is formed in a frustum shape as shown in FIG. 6. That is, the main body portion 51 is formed in a circular shape when viewed from the +Z direction, and the outer diameter of the main body portion 51 increases as it goes in the -Z direction. The main body portion 51 has a concave portion 511 and an arrangement portion 512. The concave portion 511 is provided at a position including the rotation axis Rx when viewed from the +Z direction. The concave portion 511 is recessed from the +Z-direction surface 51A in the -Z direction and is formed in a circular shape when viewed from the +Z direction. A cylindrical portion 52 protruding in the -Z direction is provided at the center of the bottom of the concave portion 511, and a plurality of openings 5111 for exposing the claw portions 562 of the engagement piece 56 described later are provided on the inner surface of the concave portion 511. A sheet member SM for reducing the frictional resistance of the plate 6 with respect to the first rotating body 5 is arranged on the bottom surface 511A of the concave portion 511. As a material of the sheet member SM, HDPE (high-density polyethylene) can be exemplified. However, it is not limited to this, and the material of the sheet member SM can be appropriately changed. The arrangement portion 512 is provided outside the concave portion 511 when viewed from the +Z direction on the +Z-direction surface 51A. That is, the arrangement portion 512 is provided along the periphery of the first rotating body 5 centered on the rotation axis Rx. More specifically, the arrangement portion 512 is provided in a ring shape along the circumferential direction centered on the rotation axis Rx and is a concave portion recessed from the surface 51A in the -Z direction. A friction adjustment member 8 is detachably arranged in the arrangement portion 512.

[0020] As shown in Fig. 7, the cylindrical portion 52 is formed in a cylindrical shape. As shown in Fig. 8, bearings BR1 and BR2 are provided inside the cylindrical portion 52 in series at a predetermined interval along the +Z direction. Each of the bearings BR1 and BR2 is a radial bearing, and in this embodiment, it is a ball bearing (deep groove ball bearing). The inner rings BR11 and BR21 of the bearings BR1 and BR2 are fixed to the peripheral surface of the shaft portion 42, and the outer rings BR12 and BR22 are fixed to the cylindrical portion 52. With such bearings BR1 and BR2, the first rotating body 5 is rotatably supported by the shaft portion 42. Note that the bearings BR1 and BR2 are not limited to ball bearings, and may be other radial bearings such as angular contact ball bearings, or may be sliding bearings.

[0021] As shown in Fig. 7, the rotation detection disk 53 is a disk-shaped member having a circular shape when viewed from the -Z direction. As shown in Fig. 8, the rotation detection disk 53 is fixed to the surface 51B in the -Z direction of the main body portion 51. Although not shown, a plurality of slits extending radially around the rotation axis Rx are arranged along the circumferential direction around the rotation axis Rx on the rotation detection disk 53. A part of the periphery of the rotation detection disk 53 where the plurality of slits are provided is inserted into the photointerrupter included in the first detection unit 43. Thereby, the rotation state of the first rotating body 5 is detected by the first detection unit 43.

[0022] As shown in Figs. 7 and 8, the holding member 54 is disposed in the -Z direction with respect to the rotation detection disk 53, and is fixed to the surface 51B together with the rotation detection disk 53 by a screw S1. The holding member 54 is a disk that holds a magnet 55 on its surface in the -Z direction. The magnet 55 is provided on the surface of the holding member 54 facing the -Z direction. The magnet 55 acts on the drive device 44 to rotate the first rotating body 5 about the rotation axis Rx.

[0023] The engaging piece 56 corresponds to the first engaging portion, engages with the second rotating body 9, and suppresses the detachment of the second rotating body 9 from the operating element body 3. As shown in FIG. 6, a plurality of engaging pieces 56 are arranged at equal intervals along the circumferential direction centered on the rotation axis Rx when viewed from the +Z direction. In the present embodiment, four engaging pieces 56 are provided. Each engaging piece 56 is formed in a substantially L shape as shown in FIG. 8. The engaging piece 56 has a mounting portion 561, a claw portion 562, and an elastic portion 563.

[0024] The mounting portion 561 is a portion along the XY plane. A screw S2 is inserted through the mounting portion 561, and the engaging piece 56 is attached to the main body portion 51 by fixing the screw S2 to the peripheral portion of the surface 51B of the main body portion 51. The claw portion 562 is formed in a claw shape. The claw portion 562 is exposed into the recess 511 through the opening 5111. The claw portion 562 is inserted into the engaging portion 96 of the second rotating body 9 to suppress the detachment of the second rotating body 9 from the first rotating body 5, that is, the detachment of the second rotating body 9 from the operating element body 3.

[0025] The elastic portion 563 is provided between the mounting portion 561 and the claw portion 562 and is a portion that can be elastically deformed toward the mounting portion 561 side. When the second rotating body 9 is attached to the operating element body 3, when the claw portion 562 is pressed radially outward about the rotation axis Rx by the second rotating body 9, the elastic portion 563 elastically deforms toward the mounting portion 561 side and allows the claw portion 562 to move toward the mounting portion 561 side. On the other hand, when the pressing of the claw portion 562 by the second rotating body 9 is released, the elastic portion 563 moves the claw portion 562 to the side opposite to the mounting portion 561. Thereby, the state in which the claw portion 562 can engage with the second rotating body 9 is maintained.

[0026] [Configuration of the Plate] FIG. 9 is a perspective view of the plate 6 viewed from the +Z direction, and FIG. 10 is a perspective view of the plate 6 viewed from the -Z direction. As shown in FIGS. 9 and 10, the plate 6 is formed in a substantially disk shape. The plate 6 is attached to the shaft portion 42 so as to be rotatable about the rotation axis Rx, and is disposed within the concave portion 511 of the first rotating body 5. The plate 6 is connected to the second rotating body 9 and, together with the second rotating body 9, is rotatable about the rotation axis Rx independently of the first rotating body 5. As shown in FIG. 9, the plate 6 includes a rotation detection disk 61, and as shown in FIGS. 9 and 10, the plate 6 also includes a support member 62.

[0027] As shown in FIG. 9, the rotation detection disk 61 is formed in a ring shape when viewed from the +Z direction and is fixed to the support member 62. A plurality of slits (not shown) are provided in the inner edge side portion of the rotation detection disk 61 on the +Z direction surface. Similar to the plurality of slits of the rotation detection disk 53, the plurality of slits are provided radially about the rotation axis Rx and are arranged along the circumferential direction about the rotation axis Rx. The portion of the rotation detection disk 61 where the plurality of slits are provided is disposed at a position overlapping with a second detection portion 73 (see FIGS. 12 and 13) described later when viewed from the +Z direction. Although details will be described later, the second detection portion 73 uses the plurality of slits to detect the rotation state of the plate 6 and, thus, the rotation state of the second rotating body 9.

[0028] The support member 62 is rotatably supported by the shaft portion 42 while supporting the rotation detection disk 61. The support member 62 has an opening 63, a protruding portion 64, and a plurality of notches 65. The opening 63 is provided in a circular shape at the center of the plate 6 when viewed from the +Z direction. A bearing BR3 is provided within the opening 63. The inner ring BR31 of the bearing BR3 is fixed to the shaft portion 42 (see FIG. 6), and the outer ring BR32 is fixed to the inner edge of the opening 63. By fixing the inner ring BR31 of such a bearing BR3 to the shaft portion 42, the plate 6 is rotatably attached to the shaft portion 42. In the present embodiment, a sliding bearing is adopted as the bearing BR3. However, the present invention is not limited thereto, and a rolling bearing may be adopted as the bearing BR3.

[0029] As shown in Fig. 9, the protrusion 64 protrudes in the +Z direction from the peripheral edge of the plate 6. When the plate 6 and the second rotating body 9 are connected, the protrusion 64 is inserted into the recess 99 of the second rotating body 9 from the -Z direction. Each of the plurality of notches 65 is provided at the peripheral edge of the plate 6. When the plate 6 and the second rotating body 9 are connected, the protrusion 98 of the second rotating body 9 is inserted into each notch 65 from the +Z direction. Note that one protrusion 64 and the plurality of notches 65 are provided at equal intervals along the circumferential direction centered on the rotation axis Rx at the peripheral edge of the plate 6. In the present embodiment, three notches 65 are provided. Among the four portions that are equally spaced in the circumferential direction centered on the rotation axis Rx, one protrusion 64 is arranged in one portion, and the remaining three portions are provided with notches 65.

[0030] The -Z direction surface 62A of the support member 62, that is, the -Z direction surface of the plate 6, is in contact with the bottom surface 511A (see Fig. 6) of the recess 511 of the first rotating body 5 via the sheet member SM (see Fig. 6). For this reason, when the first rotating body 5 is rotated about the rotation axis Rx, the plate 6 rotates integrally with the first rotating body 5. On the other hand, when the second rotating body 9 connected to the support member 62 is rotated about the rotation axis Rx, the plate 6 rotates integrally with the second rotating body 9 while sliding along the bottom surface 511A. However, the sheet member SM is not necessarily provided, and the surface 62A and the bottom surface 511A may be in direct contact.

[0031] [Configuration of the display unit] The display unit 7 displays an image according to the image information input from the control unit. The display unit 7 is arranged at the center of the rotation operator 2 in the +Z direction. More specifically, the display unit 7 is arranged at a position in the +Z direction relative to the plate 6 within the recess 511 of the first rotating body 5, and as shown in Figs. 4 and 5, is arranged at a position overlapping the rotation axis Rx when viewed from the +Z direction. The outer diameter of the display unit 7 when viewed from the +Z direction is smaller than the outer diameter of the plate 6 when viewed from the +Z direction. Such a display unit 7 is fixed to the shaft portion 42, and the rotation of the display unit 7 about the rotation axis Rx is restricted.

[0032] FIG. 11 is a perspective view of the display unit 7 viewed from the +Z direction, and FIG. 12 is a perspective view of the display unit 7 viewed from the -Z direction. As shown in FIGS. 11 and 12, the display unit 7 includes a display panel 71, a housing portion 72, and a second detection unit 73. The display panel 71 is connected to the control unit via a cable CA, and displays an image according to the image information input from the control unit.

[0033] FIG. 13 is a plan view of the display unit 7 with the cover 723 removed from the housing main body 721, viewed from the +Z direction. The housing portion 72 includes a housing main body 721 that houses the display panel 71 and the second detection unit 73, and a cover 723 that is detachably attached to the housing main body 721. When the cover 723 is removed from the housing main body 721, as shown in FIG. 13, the second detection unit 73 provided on the housing main body 721 is exposed in the +Z direction. As shown in FIG. 12, the housing main body 721 has a cylindrical fixing portion 722 that protrudes in the -Z direction from the central position when viewed from the -Z direction. The fixing portion 722 is a portion fixed to the shaft portion 42.

[0034] The second detection unit 73 detects the rotation state of the plate 6 as the rotation state of the second rotating body 9, and outputs the detected rotation state of the second rotating body 9 to the above-described control unit via the cable CA. In the present embodiment, similar to the first detection unit 43, the second detection unit 73 has a photo interrupter that detects the light passing through the slit provided in the plate 6 to detect the rotation state of the plate 6, and thus the rotation state of the second rotating body 9. However, the second detection unit 73 may have other configurations as long as it can detect the rotation state of the second rotating body 9.

[0035] [Configuration of Friction Adjusting Member] As shown in FIGS. 4 and 5, the friction adjustment member 8 is a ring-shaped sheet member disposed in the placement portion 512 of the first rotating body 5. When the second rotating body 9 is attached to the operator body 3, the friction adjustment member 8 is disposed between the first rotating body 5 and the second rotating body 9 to adjust the frictional force between the first rotating body 5 and the second rotating body 9. That is, the friction adjustment member 8 adjusts the frictional force during the user's operation on the second rotating body 9. In the present embodiment, two friction adjustment members 8 are provided. However, the number of the friction adjustment members 8 disposed in the placement portion 512 and between the first rotating body 5 and the second rotating body 9 is not limited to this and can be appropriately changed. For example, when it is desired to increase the frictional force, more friction adjustment members 8 are disposed, and when it is desired to decrease the frictional force, fewer friction adjustment members 8 are disposed. That is, the frictional force when one friction adjustment member 8 is disposed between the first rotating body 5 and the second rotating body 9 is smaller than the frictional force when two friction adjustment members 8 are disposed. Also, even when one friction adjustment member 8 is disposed, the frictional force by the friction adjustment member 8 with a small thickness is smaller than the frictional force by the friction adjustment member 8 with a large thickness. Also in the present embodiment, the friction adjustment member 8 is formed of a resin containing PET (polyethylene terephthalate). However, the friction adjustment member 8 is not limited to this and may have a portion constituted by felt or may be formed of other resins. That is, the material of the friction adjustment member 8 is not limited to PET and may be, for example, felt. Thus, the frictional force can also be adjusted by disposing the friction adjustment member 8 formed of a material different from PET. Furthermore, the frictional force can also be adjusted by the thickness of the friction adjustment member 8. That is, the frictional force can be adjusted by adjusting the number, thickness, and material of the friction adjustment members 8 disposed between the first rotating body 5 and the second rotating body 9.

[0036] [Configuration of the Second Rotating Body] FIG. 14 is a perspective view of the plate 6 and the second rotating body 9 viewed from the +Z direction, and FIG. 15 is a perspective view of the plate 6 and the second rotating body 9 viewed from the -Z direction. The second rotating body 9 is provided on the operator body 3 so as to be rotatable about the rotation axis Rx. The second rotating body 9 rotates integrally with the first rotating body 5 and is also provided so as to be rotatable independently of the first rotating body 5 clockwise and counterclockwise according to the operation of the user. Specifically, the second rotating body 9 is placed on the first rotating body 5 so as to cover the display unit 7 and the friction adjusting member 8 in the +Z direction, and contacts the first rotating body 5 and rotates about the rotation axis Rx together with the first rotating body 5. Further, the second rotating body 9 is connected to the plate 6 and can rotate about the rotation axis Rx together with the plate 6 independently of the first rotating body 5. The second rotating body 9 includes an operation panel 91 and a support member 92.

[0037] The operation panel 91 is a portion that is touched by the user when the user rotates the second rotating body 9 in the second rotating body 9. The operation panel 91 is a disk that constitutes the +Z direction surface of the second rotating body 9 and is attached to the support member 92. When the second rotating body 9 is attached to the operator body 3, the operation panel 91 covers the display unit 7 and the friction adjusting member 8 in the +Z direction. The operation panel 91 has a light transmitting portion 911 at the center of the operation panel 91 as viewed from the +Z direction. That is, the operation panel 91 has a light transmitting portion 911 at a position corresponding to the display panel 71 of the display unit 7 as viewed from the +Z direction. The light transmitting portion 911 transmits the light emitted from the display unit 7. The user can observe the image displayed by the display unit 7 through the light transmitting portion 911.

[0038] The support member 92 supports the operation panel 91 and is connected to the plate 6. The support member 92 has an opening 93, a support portion 94, a cylindrical portion 95, an engaging portion 96, and a connecting portion 97. The opening 93 is formed in a circular shape at the center of the support member 92 as viewed from the +Z direction. The support portion 94 supports the operation panel 91 on the +Z direction surface. The support portion 94 is formed in a ring shape having substantially the same outer diameter as the +Z direction surfaces of the operation panel 91 and the first rotating body 5 outside the opening 93 as viewed from the +Z direction. Therefore, when the second rotating body 9 is attached to the operator body 3, the friction adjusting member 8 is covered in the +Z direction by the support portion 94.

[0039] Incidentally, although illustration is omitted, when the second rotating body 9 and the plate 6 are connected, if the friction adjusting member 8 is not disposed in the disposing portion 512 of the first rotating body 5, a gap is formed between the surface 94A of the supporting portion 94 and the disposing portion 512. In other words, the second rotating body 9 contacts the first rotating body 5 via the friction adjusting member 8. In the present embodiment, the disposing portion 512 and the supporting portion 94 are connected via the friction adjusting member 8, and the disposing portion 512 is used as a sliding surface of the friction adjusting member 8 and the second rotating body 9. Thereby, the load generated when the user scratches the operation panel 91 can be dispersed by the friction adjusting member 8 and transmitted to the first rotating body 5. Then, as described above, according to the number, thickness, and material of the friction adjusting member 8, the operation feeling when the second rotating body 9 is relatively rotated with respect to the first rotating body 5 can be made different.

[0040] FIG. 16 is a view showing an enlarged part of a cross section of the second rotating body 9 along the XZ plane. As shown in FIG. 16, a stepped portion 941 is provided at the peripheral edge of the supporting portion 94. That is, the second rotating body 9 has a stepped portion 941 provided at the peripheral edge of the supporting portion 94. The stepped portion 941 makes the outer diameter of the -Z direction portion of the supporting member 92 smaller than the outer diameter of the +Z direction portion. That is, the stepped portion 941 makes the outer diameter of the portion of the supporting member 92 on the first rotating body 5 side smaller than the outer diameter of the portion on the side opposite to the first rotating body 5. By inserting a fingernail of the user into such a stepped portion 941, it becomes easy to remove the second rotating body 9 from the operating element body 3. In the present embodiment, the stepped portion 941 is provided in the +Z direction with respect to the +Z direction surface 51A of the first rotating body 5. Therefore, the fingernail of the user is easily caught by the stepped portion 941.

[0041] As shown in Fig. 15, the cylindrical portion 95 protrudes cylindrically in the -Z direction from the inner edge of the opening 93. When the second rotating body 9 is placed on the first rotating body 5, the cylindrical portion 95 is inserted into the concave portion 511 of the first rotating body 5 from the +Z direction. That is, the outer diameter of the cylindrical portion 95 is smaller than the inner diameter of the concave portion 511 formed in a circular shape when viewed from the +Z direction. When the second rotating body 9 is attached to the operator body 3, the display portion 7 is disposed inside the cylindrical portion 95.

[0042] The engaging portion 96 corresponds to the second engaging portion. The engaging portion 96 is provided on the outer peripheral surface of the cylindrical portion 95 along the circumferential direction centered on the rotation axis Rx. The engaging portion 96 is a concave portion along the circumferential direction centered on the rotation axis Rx and is recessed toward the rotation axis Rx. In other words, the engaging portion 96 is a groove portion along the circumferential direction. When the second rotating body 9 is attached to the operator body 3, the claw portion 562 of the engaging piece 56 provided on the first rotating body 5 is inserted into the engaging portion 96. Thereby, the detachment of the second rotating body 9 from the operator body 3 (the first rotating body 5) is restricted. As described above, the engaging piece 56 has an elastic portion 563 that can be elastically deformed toward the mounting portion 561 side of the claw portion 562, that is, radially outward about the rotation axis Rx. For this reason, when the second rotating body 9 is pulled upward in the +Z direction from the operator body 3 (the first rotating body 5) with a force equal to or greater than a predetermined force, the claw portion 562 is disengaged from the engaging portion 96. Thereby, the second rotating body 9 can be removed from the operator body 3.

[0043] The connecting portion 97 is a portion of the second rotating body 9 that is connected to the plate 6. The connecting portion 97 is provided at the -Z direction end of the cylindrical portion 95. The connecting portion 97 includes protruding portions 98 provided at three of four portions provided at equal intervals along the circumferential direction centered on the rotation axis Rx when viewed from the -Z direction, and one concave portion 99 provided at one portion. The three protruding portions 98 protrude in the -Z direction from the -Z direction end of the cylindrical portion 95. Each protruding portion 98 is inserted into the corresponding notch 65 of the plurality of notches 65 provided on the plate 6 from the +Z direction. One recess 99 is recessed in the +Z direction from the end in the -Z direction of the cylindrical portion 95. The protruding portion 64 of the plate 6 is inserted into the recess 99 from the -Z direction.

[0044] [Cross-sectional structure of the rotary operator] FIG. 17 is a view showing an enlarged part of a cross-section along the XZ plane of the rotary operator 2. As described above, the second rotating body 9 is placed on the first rotating body 5, contacts the first rotating body 5 directly or via the friction adjusting member 8, and is connected to the plate 6 which is the third rotating body fixed to the shaft portion 42 so as to be rotatable about the rotation axis Rx. Thus, the second rotating body 9 rotates integrally with the first rotating body 5 about the rotation axis Rx, and rotates integrally with the plate 6 separately from the first rotating body 5 about the rotation axis Rx according to the rotation operation of the user. Further, when the second rotating body 9 is removed, the arrangement portion 512 of the first rotating body 5 is exposed, and the friction adjusting member 8 arranged between the first rotating body 5 and the second rotating body 9 can be exchanged. The characteristics of such an acoustic control device 1 will be described in detail with reference to FIG. 17.

[0045] The first rotating body 5 is supported by the shaft portion 42 so as to be rotatable about the rotation axis Rx by fixing the inner rings BR11, BR21 of the bearings BR1, BR2 provided in the cylindrical portion 52 to the shaft portion 42 of the base member 4. The first rotating body 5 is rotated clockwise or counterclockwise as viewed from the +Z direction by a plurality of magnets 55 provided on the holding member 54 by a driving device 44 arranged in the recess 411 of the base member 4. The plate 6 is supported by the shaft portion 42 so as to be rotatable about the rotation axis Rx by fixing the inner ring BR31 of the bearing BR3 provided in the opening 63 to the shaft portion 42. In the +Z direction with respect to the plate 6, a display portion 7 fixed to the shaft portion 42 is arranged.

[0046] The second rotating body 9 is arranged so as to cover the display portion 7 and the arrangement portion 512 of the first rotating body 5 in the +Z direction, and the friction adjusting member 8 arranged in the arrangement portion 512 is arranged between the first rotating body 5 and the second rotating body 9. The cylindrical portion 95 of the second rotating body 9 is inserted into the concave portion 511 of the first rotating body 5, the protruding portion 98 of the second rotating body 9 is inserted into the notch 65 of the plate 6, and the protruding portion 64 (see FIG. 9) of the plate 6 is inserted into the concave portion 99 (see FIG. 15) of the second rotating body 9, whereby the second rotating body 9 is connected to the plate 6. Thereby, the second rotating body 9 and the plate 6 are integrated, and the second rotating body 9 is supported by the shaft portion 42 so as to be rotatable about the rotation axis Rx via the plate 6. Since such a second rotating body 9 is placed on the first rotating body 5, it rotates integrally with the first rotating body 5. On the other hand, since the second rotating body 9 is in contact with the first rotating body 5 via the friction adjusting member 8, it can rotate relatively about the rotation axis Rx with respect to the first rotating body 5. That is, the second rotating body 9 can rotate independently of the first rotating body 5. The rotation state of the first rotating body 5 is detected by the first detection unit 43 (see FIG. 6) provided in the base member 4, and the rotation state of the second rotating body 9 is detected by the second detection unit 73 provided in the display unit 7 fixed to the shaft portion 42 detecting the rotation state of the plate 6.

[0047] Note that the claw portion 562 of the engaging piece 56 as the first engaging portion in the first rotating body 5 is arranged to be engageable with the engaging portion 96 as the second engaging portion in the second rotating body 9. Thereby, the detachment of the second rotating body 9 from the operating element main body 3 is restricted. On the other hand, when the second rotating body 9 is pulled upward in the +Z direction by a force equal to or greater than a predetermined force, a pressing force acting radially outward about the rotation axis Rx acts on the claw portion 562 in contact with the engaging portion 96. Due to the pressing force, the elastic portion 563 is elastically deformed, and the claw portion 562 moves radially outward about the rotation axis Rx. Thereby, the second rotating body 9 can be removed from the operating element main body 3, and the friction adjusting member 8 provided in the arrangement portion 512 of the first rotating body 5 is exposed, and the friction adjusting member 8 can be replaced.

[0048] [Effects of the Embodiment] The acoustic control device 1 according to the present embodiment described above has the following effects. The acoustic control device 1 functions as an operating device including the rotary operating element 2. The rotation operator 2 includes a first rotating body 5, a friction adjustment member 8, and a second rotating body 9. The first rotating body 5 is rotatable about an imaginary rotation axis Rx. The second rotating body 9 is provided detachably attached to the operator body 3. The second rotating body 9 is rotated integrally with the first rotating body 5 and is rotatable about the rotation axis Rx independently of the first rotating body 5. The friction adjustment member 8 is covered by the second rotating body 9 as viewed from the side of the second rotating body 9 with respect to the first rotating body 5, and adjusts the frictional force between the first rotating body 5 and the second rotating body 9. The first rotating body 5 has a placement portion 512 where the friction adjustment member 8 is detachably arranged, and an engagement piece 56. The engagement piece 56 corresponds to a first engagement portion. The second rotating body 9 has an engagement portion 96 with which the claw portion 562 of the engagement piece 56 can engage. The engagement portion 96 corresponds to a second engagement portion.

[0049] According to such a configuration, by removing the second rotating body 9 that covers the friction adjustment member 8, the friction adjustment member 8 arranged in the placement portion 512 can be exposed. Thereby, by replacing the friction adjustment member 8, the frictional force between the first rotating body 5 and the second rotating body 9 can be adjusted. Therefore, the frictional force can be adjusted according to the user's preference, and the operation feeling of the rotation operator can be adjusted according to the user. Further, the claw portion 562 of the engagement piece 56 of the first rotating body 5 can engage with the engagement portion 96 of the second rotating body 9. And the claw portion 562 restricts the detachment of the second rotating body 9 by engaging with the engagement portion 96. Thereby, it is possible to prevent the second rotating body 9 from being unexpectedly removed from the operator body 3.

[0050] The rotation operator 2 includes a drive device 44 that rotates the first rotating body 5. According to such a configuration, the first rotating body 5 can always be rotated when the rotation operator 2 is used. For this reason, the rotation operator 2 can be configured like a turntable that rotates a record turntable.

[0051] In the rotation operator 2, the friction adjustment member 8 has a ring shape centered on the rotation axis Rx. The placement portion 512 is provided along the periphery of the first rotating body 5 centered on the rotation axis Rx. According to such a configuration, since the friction adjustment member 8 is ring-shaped, the frictional force between the first rotating body 5 and the second rotating body 9 can be adjusted substantially uniformly in the circumferential direction centered on the rotation axis Rx. Therefore, it is possible to easily adjust the operating feeling of the rotation operator 2.

[0052] The rotation operator 2 is provided between the first rotating body 5 and the second rotating body 9, and includes a plate 6 that can rotate about the rotation axis Rx independently of the first rotating body 5. The plate 6 corresponds to the third rotating body. The second rotating body 9 has a connecting portion 97 connected to the plate 6. According to such a configuration, since the second rotating body 9 is connected to the plate 6 that can rotate about the rotation axis Rx independently of the first rotating body 5, the second rotating body 9 can be configured to be rotatable about the rotation axis Rx independently of the first rotating body 5.

[0053] The rotation operator 2 includes a second detection unit 73 that detects the rotation state of the plate 6 as the rotation state of the second rotating body 9. According to such a configuration, the second detection unit 73 can be arranged inside the first rotating body 5. Therefore, the rotation operator 2 can be configured more compactly compared to the case of directly detecting the rotation state of the second rotating body 9.

[0054] The rotation operator 2 includes a display unit 7 arranged at a position overlapping the rotation axis Rx when viewed from the second rotating body 9 side with respect to the first rotating body 5. According to such a configuration, various displays can be implemented by the display unit 7 provided on the rotation operator 2. Therefore, the versatility of the rotation operator 2 can be enhanced. Also, it is possible to easily arrange the display unit 7 at the center of the second rotating body 9 when viewed from the +Z direction. Thereby, it is possible for the user to easily observe the display by the display unit 7.

[0055] In the rotation operator 2, the second rotating body 9 has a light-transmitting portion 911 at a position covering the display unit 7 when viewed from the second rotating body 9 side with respect to the first rotating body 5. According to such a configuration, the second rotating body 9 can be provided so as to cover the display unit 7. According to this, compared with the case where the second rotating body 9 is provided while avoiding the display unit 7, the area of the second rotating body 9 that the user can contact can be expanded. Therefore, the operability of the second rotating body 9 can be improved. Further, since the second rotating body 9 that covers the display unit 7 has the light-transmitting portion 911, the display by the display unit 7 can be visually recognized through the light-transmitting portion 911.

[0056] In the rotation operator 2, the first rotating body 5 includes the rotation axis Rx when viewed along the rotation axis Rx, and has a concave portion 511 that is recessed on the side opposite to the second rotating body 9. That is, the first rotating body 5 includes the rotation axis Rx when viewed from the +Z direction, and has a concave portion 511 that is recessed in the -Z direction. The plate 6 as the third rotating body and the display unit 7 are disposed in the concave portion 511. According to such a configuration, since the plate 6 and the display unit 7 are provided in the concave portion 511 of the first rotating body 5, the rotation operator 2 can be configured compactly.

[0057] In the rotation operator 2, the second rotating body 9 has a cylindrical portion 95. The cylindrical portion 95 is formed in a cylindrical shape centered on the rotation axis Rx and is inserted into the concave portion 511. The engaging portion 96 as the second engaging portion is provided on the cylindrical portion 95. According to such a configuration, since the cylindrical portion 95 is inserted into the concave portion 511, it is possible to prevent the second rotating body 9 from accidentally detaching from the first rotating body 5. Further, the engaging portion 96 is provided on the cylindrical portion 95. According to this, it is possible to easily maintain the engagement state between the claw portion 562 of the engaging piece 56 as the first engaging portion and the engaging portion 96 inside the first rotating body 5, and prevent the second rotating body 9 from accidentally detaching from the first rotating body 5. Therefore, the second rotating body 9 can be stably rotated.

[0058] In the rotation operator 2, the plate 6 as the third rotating body is provided on the side opposite to the second rotating body 9 with respect to the display unit 7. According to such a configuration, the display unit 7 is sandwiched between the second rotating body 9 and the plate 6. According to this, the plate 6 can be disposed in the concave portion 511 without blocking the display by the display unit 7. Therefore, the rotation operator 2 can be configured compactly.

[0059] The rotation operator 2 includes a shaft portion 42. The shaft portion 42 constitutes a rotation axis Rx and individually supports each of the first rotating body 5 and the plate 6 rotatably. According to such a configuration, not only can the first rotating body 5 be stably supported, but also the second rotating body 9 connected to the plate 6 can be stably supported.

[0060] In the rotation operator 2, the second rotating body 9 has a stepped portion 941. The stepped portion 941 is provided at the periphery of the support portion 94 of the second rotating body 9 and makes the outer diameter of the portion on the first rotating body 5 side smaller than the outer diameter of the portion on the side opposite to the first rotating body 5. According to such a configuration, when detaching the second rotating body 9 from the first rotating body 5, for example, it is possible to easily insert a finger nail into the stepped portion 941 of the second rotating body 9. Therefore, the operation when detaching the second rotating body 9 from the first rotating body 5 can be simplified.

[0061] In the rotation operator 2, the friction adjustment member 8 is formed of a resin containing polyethylene terephthalate. According to such a configuration, compared with the case where the friction adjustment member 8 is formed of felt or other resins, when the friction adjustment member 8 is interposed, the second rotating body 9 can be smoothly rotated with respect to the first rotating body 5. Therefore, by adjusting the number of friction adjustment members 8 disposed between the first rotating body 5 and the second rotating body 9 or the like, it is easy to adjust the frictional force between the first rotating body 5 and the second rotating body 9, and thus the operation feeling of the second rotating body 9.

[0074] In the above embodiment, it was assumed that the rotary operator 2 was provided in the acoustic control device 1 having the function of the operating device. That is, it was assumed that the acoustic control device 1 includes the rotary operator 2. However, the present invention is not limited to this, and the present invention is applicable to a rotary operator provided in an operating device. Further, the rotary operator according to the present invention can be used alone. Furthermore, even when the rotary operator of the present invention is applied to an operating device and an acoustic control device, the configurations of the operating device and the acoustic control device are not limited to the above-described configurations, and may have other configurations.

[0075] [Summary of the Invention] The summary of the present invention is appended below. [1] The rotary operator includes a first rotating body that can rotate about a virtual rotation axis, a second rotating body that is detachably provided and rotates integrally with the first rotating body and can rotate about the rotation axis individually from the first rotating body, and a friction adjustment member that is covered by the second rotating body when viewed from the second rotating body side with respect to the first rotating body and adjusts the frictional force between the first rotating body and the second rotating body. The first rotating body has an arrangement portion where the friction adjustment member is detachably arranged and a first engaging portion. The second rotating body has a second engaging portion with which the first engaging portion can engage.

[0076] According to such a configuration, by removing the second rotating body that covers the friction adjustment member, the friction adjustment member arranged in the arrangement portion can be exposed. Thereby, the frictional force between the first rotating body and the second rotating body can be adjusted by replacing the friction adjustment member or performing an operation of adjusting the frictional force generated by the friction adjustment member on the friction adjustment member. Therefore, the frictional force can be adjusted according to the user's preference, and the operation feeling of the rotary operator can be adjusted according to the user. Further, the first engaging portion of the first rotating body can be engaged with the second engaging portion of the second rotating body. Therefore, for example, when one of the first engaging portion and the second engaging portion restricts the detachment of the second rotating body, it is possible to prevent the second rotating body from being unexpectedly removed. On the other hand, for example, when one of the first engaging portion and the second engaging portion guides the rotation of the second rotating body, the relative rotation of the second rotating body with respect to the first rotating body can be stably performed.

[0077] [2][1] The rotary operator according to [1] may further include a driving device for rotating the first rotating body. According to such a configuration, the first rotating body can always be rotated when the rotary operator is used. Therefore, the rotary operator can be configured like a turntable that rotates a record disc.

[0078] [3][1] or [2] In the rotary operator according to [1], the friction adjusting member may have a ring shape centered on the rotary shaft, and the arranging portion may be provided along the periphery of the first rotating body centered on the rotary shaft. According to such a configuration, since the friction adjusting member has a ring shape, the frictional force between the first rotating body and the second rotating body can be adjusted substantially uniformly in the circumferential direction centered on the rotary shaft. Therefore, it is possible to easily adjust the operating feeling of the rotary operator.

[0079] [4][3] In the rotary operator according to [3], a third rotating body is provided between the first rotating body and the second rotating body and is rotatable about the rotary shaft independently of the first rotating body, and the second rotating body may have a connecting portion connected to the third rotating body. According to such a configuration, since the second rotating body is connected to the third rotating body that is rotatable about the rotary shaft independently of the first rotating body, the second rotating body can be configured to be rotatable about the rotary shaft independently of the first rotating body.

[0080] [5][4] In the rotary operator according to [4], a detecting portion for detecting the rotational state of the third rotating body as the rotational state of the second rotating body may be provided. According to such a configuration, the detection unit can be arranged inside the first rotating body. Therefore, compared with the case of directly detecting the rotation state of the second rotating body, the rotating operator can be configured in a more compact manner.

[0081] In the rotating operator according to [6][4] or [5], a display unit may be provided at a position overlapping the rotation axis when viewed from the second rotating body side with respect to the first rotating body. According to such a configuration, various displays can be implemented by the display unit provided on the rotating operator. Therefore, the versatility of the rotating operator can be enhanced. Also, when viewed from the second rotating body side with respect to the first rotating body, the display unit can be easily arranged at the center of the second rotating body. Thereby, it is possible to make it easier for the user to observe the display by the display unit.

[0082] In the rotating operator according to [7][6], the second rotating body may have a light-transmitting portion at a position covering the display unit when viewed from the second rotating body side with respect to the first rotating body. According to such a configuration, the second rotating body can be provided so as to cover the display unit. According to this, compared with the case where the second rotating body is provided while avoiding the display unit, the area of the second rotating body that the user can contact can be expanded. Therefore, the operability of the second rotating body can be enhanced. Further, since the second rotating body covering the display unit has a light-transmitting portion, the display by the display unit can be visually recognized through the light-transmitting portion.

[0083] In the rotating operator according to [8][7], the first rotating body has a concave portion that includes the rotation axis when viewed along the rotation axis and is recessed on the side opposite to the second rotating body, and the third rotating body and the display unit may be arranged in the concave portion. According to such a configuration, since the third rotating body and the display unit are provided in the concave portion of the first rotating body, the rotating operator can be configured in a more compact manner.

[0084] In the rotary operator described in [9][8], the second rotating body is formed in a cylindrical shape centered on the rotation axis and has a cylindrical portion inserted into the concave portion, and the second engaging portion may be provided on the cylindrical portion. According to such a configuration, since the cylindrical portion is inserted into the concave portion, it is possible to prevent the second rotating body from accidentally detaching from the first rotating body. Further, the second engaging portion is provided on the cylindrical portion. According to this, it is possible to easily maintain the engaged state between the first engaging portion and the second engaging portion inside the first rotating body, and to prevent the second rotating body from accidentally detaching from the first rotating body. Therefore, the second rotating body can be stably rotated.

[0085] In the rotary operator according to any one of

[10] [6] to [9], the third rotating body may be provided on the side opposite to the second rotating body with respect to the display portion. According to such a configuration, the display portion is sandwiched between the second rotating body and the third rotating body. According to this, the third rotating body can be arranged in the concave portion without blocking the display by the display portion. Therefore, the rotary operator can be configured compactly.

[0086] In the rotary operator according to any one of

[11] [4] to

[10] , a shaft portion that constitutes the rotation axis and individually supports each of the first rotating body and the third rotating body so as to be rotatable may be provided. According to such a configuration, the first rotating body can be stably supported, and the second rotating body connected to the third rotating body can be stably supported.

[0087] In the rotary operator according to any one of

[12] [1] to

[11] , the second rotating body may be provided on the periphery of the second rotating body and have a stepped portion that makes the outer diameter of the portion on the first rotating body side smaller than the outer diameter of the portion on the side opposite to the first rotating body. According to such a configuration, when detaching the second rotating body from the first rotating body, for example, a finger nail can be easily inserted into the stepped portion of the second rotating body. Therefore, the operation when detaching the second rotating body from the first rotating body can be simplified.

[0088]

[13] In the rotary operator according to any one of [1] to

[12] , the friction adjusting member may be formed of a resin containing polyethylene terephthalate. According to such a configuration, compared with the case where the friction adjusting member is formed of felt or other resin, when the friction adjusting member is interposed, the second rotating body can be smoothly rotated with respect to the first rotating body. Therefore, by adjusting the number of friction adjusting members disposed between the first rotating body and the second rotating body, etc., it is possible to easily adjust the frictional force between the first rotating body and the second rotating body, and thus the operating feeling of the second rotating body.
