The support member 4 is provided with mounting holes 4a, 4a having substantially the same inner diameter as the outer diameters of the steps 3a, 3a, and holding holes 4b, 4b for mounting the rotary operation component 6, respectively. An interval L2 is set between the mounting holes 4a. The distance between the holding holes 4b and 4b is set to be the same as the distance L between the mounting holes 1a and 1b. Distance L1 between posts 3 and 3 and mounting hole 4
The distance L2 between the holes a and 4a is designed to be the same distance (L1 = L2).

[0004] As shown in FIG. 5 (B), the mounting holes 4 a of the support member 4 are inserted into the tips of the columns 3, 3, respectively, so that the mounting holes 4 a are formed in the steps 3 a, 3 a of the columns 3, 3. , 4a can be fitted. In this state, the screws 5, 5 are screwed into the screw holes 3b, 3b, so that the support member 4 is fixedly provided at the tips of the columns 3, 3. Support member 4
Is mounted with a rotary operation component 6 such as a variable resistor, a variable capacitor or a variable coil. The rotary operation component 6 includes a main body 6a, a threaded portion 6b, and an operation shaft 6c. A thread groove is threaded on the outer peripheral surface of the threaded portion 6b, and the nut 7 can be screwed into the thread groove. In FIG. 5B, the threaded portion 6b of the rotary operation component 6 is inserted into the holding hole 4b of the support member 4, and the nut 7 is fastened to the threaded portion 6b, so that the rotary operation component 6 is fixed.

[0005] A light guide member 8 is interposed between the back surface of the operation panel 1 and the support member 4. The light guide member 8 is formed of a transparent resin such as acrylic, and has insertion holes 8a, 8a through which the operation shaft 6c of the rotary operation component 6 is inserted.
It has receiving portions 8b, 8b into which the operation knobs 2, 2 are inserted, and ring-shaped ribs 8c, 8c. As shown in FIG. 5B, the light guide members 8, 8 are mounted on the back surface of the operation panel 1 with the ribs 8c, 8c fitted on the edges of the mounting holes 1a, 1b. Support member 4 on which rotary operation parts 6 and 6 are mounted

The operation shafts 6c, 6c are exposed outside the device 1. This operation axis 6
By attaching the operation knobs 2 and 2 to the tips of c and 6c, it is possible to manually adjust the rotation of the rotary operation parts 6 and 6, for example, so that volume control and sound quality adjustment such as high sound and low sound can be performed. Become.

When the operation knobs 2, 2 are mounted, the outer peripheral surfaces of the base ends of the operation knobs 2, 2 face the inner peripheral surfaces of the ribs 8c, 8c. Then, an illuminating member such as an LED or a lamp provided on the support member 4 or the like emits light,
Light transmitted through the inside of the light guide member 8 is emitted from the ribs 8c, 8c to the outside of the operation panel 1, and the area around the operation knobs 2, 2 is brightly illuminated.

[0007]

In this type of operation device, a plurality of mounting holes 1a and 1b are formed in the operation panel 1, and a plurality of rotary operation parts are mounted on a support member 4 fixed inside the operation panel 1. 6, 6 are fixed. Therefore, the tolerance of the distance L between the mounting holes 1a and 1b of the operation panel 1 is
The mounting position tolerance of the support member 4 with respect to the operation panel 1 and the tolerance of the distance L between the holding holes 4b and 4b of the pointing member 4 are accumulated, and the mounting holes 1a and 1b and the rotary operation component 6 mounted on the support member 4 are accumulated. , 6 are likely to be displaced from the rotating shafts 6c, 6c. Therefore, the operation panel 1
It is necessary to provide a clearance between the mounting holes 1a, 1a and the outer peripheral surface of the operation knob 2. However, if the clearance is not formed with a sufficient clearance size, the operation knob 2 cannot be mounted on the operation panel 1 or the outer peripheral portion of the operation knob 2 is , The rotational load may increase.

If the clearance is formed at a location hidden behind the operation knob 2, the operation panel 1 will feel uncomfortable when the operation panel 1 is viewed from the front even if the clearance is extremely large. Nothing. However, as shown in FIGS. 5A and 5B, the ribs 8c of the light guide member 8 are fitted into the mounting holes 1a and 1b of the operation panel 1, and the outer peripheral surface of the operation knob 2 faces the inside of the rib 8c. And rib 8
In the structure in which the clearance C is formed between the inner peripheral surface of the operating knob 2 and the outer peripheral surface of the operating knob 2, if the clearance is too large, the operating knob 2 will not move when the operating panel 1 is viewed from the front.
The appearance of the outer peripheral portion is impaired. Further, if the clearance C around each operation knob 2 is not uniform, the outer periphery of the operation knob 2 cannot be uniformly illuminated by the rib 8c. I feel uncomfortable.

Therefore, conventionally, as shown in FIG. 6, one mounting hole 4a of the supporting member 4 is elongated in the X-axis direction.
a ', the position of the support member 4 can be adjusted in the X direction with respect to the operation panel 1, and the mounting hole 1a of the operation panel 1 can be adjusted.
1b and the position of the rotary operation parts 6 and 6 fixed to the support member 4 can be adjusted. However, in this structure, although the relative position between the operation panel 1 and the support member 4 can be adjusted, the mounting holes 1a and 1
It is difficult to ensure that the distance L between the knob b and the distance between the centers of the rotary operation parts 6 and 6 fixed to the support member 4 is consistent, and the outer peripheral surface of the operation knob 2 and the light guide member 8 Ribs 8
It is still difficult to set the clearance C between the inner peripheral surface c and the inner peripheral surface uniformly over the entire circumference.

The present invention has been made to solve the above-mentioned conventional problems, and makes it possible to adjust a relative position between a mounting part formed on an operation panel and a rotary operation part fixed inside the operation panel. It is an object of the present invention to provide an operation device in which an operation knob can always be mounted on an operation panel with an optimum clearance.

Further, according to the present invention, when a clearance is formed between the outer peripheral surface of the operation knob and the operation panel, or between the outer peripheral surface of the operation knob and the light guide member, the clearance of the outer periphery of the operation knob is kept constant over the entire circumference. It is an object of the present invention to provide an operation device which can be operated in a timely manner.

[0012]

According to the present invention, there is provided an operation panel, a rotary operation component provided inside the operation panel, a support member for supporting the rotary operation component inside the operation panel, In an operation device provided with an operation knob rotatably inserted into the operation panel and fixed to a shaft of the rotation operation component, the rotation operation component and a movable member to which the rotation operation component is fixed, Attached to the support member with a movement margin in a direction orthogonal to the axis, a part of the movable member is hooked on the support member,
The rotation operating component and the movable member are prevented from rotating.

[0013] For example, a sleeve is inserted into an insertion hole formed in the support member with a margin for movement in a direction orthogonal to the axis, and a rotary operation component and a movable member are fixed to the sleeve. Becomes

According to the present invention, the rotary operation component is mounted on the support member provided inside the operation panel with a margin for movement. This movement allowance is preferably in all directions orthogonal to the axis of the rotary operation component. By providing this movement allowance, even if the tolerance of positional deviation is accumulated between the mounting hole or the like on which the operation knob is mounted on the operation panel and the support member, the rotation operation part and the operation panel can be fitted. The rotary operation component follows the position. Therefore, even if the operation knob does not have an excessive clearance with respect to the operation panel, the operation knob mounted on the operation panel and the shaft of the rotary operation component can be reliably connected. Further, since a part of the movable member is hung by the support member to prevent rotation, the rotation of the operation knob does not cause the rotation operation component and the movable member to rotate freely.

In the above, it is preferable that at least a part of the movable member is resiliently pressed by the support member to prevent the rotational operation component and the movable member from rattling in the axial direction with respect to the support member. .

In this case, the movable member may be resiliently pressed against the supporting member by a leaf spring or a coil spring separate from the movable member, or the movable member may be formed by a leaf spring or the like, and the movable member may be moved by itself. May be resiliently pressed by the support member. By employing this resilient structure, it is possible to prevent the rotational operation component and the movable member from rattling in the axial direction with respect to the support member, and to prevent rattle noise.

Further, a light guide member for transmitting illumination light is provided inside the operation panel, and the operation knob or the shaft is rotatably inserted into a reference hole formed in the light guide member. Is preferred.

That is, in the present invention, the operation knob or
The operation knob and the axis of the rotary operation component can be connected even if the axis of the rotary operation component has little clearance in the direction orthogonal to the axis with a minimum clearance from the reference hole.
The reference hole in this case may be formed in the operation panel,
It may be formed on the light guide member, or may be formed on components other than the operation panel and the light guide member.

Further, the light guide member has a rib formed on the outer periphery of the operation knob, and the outer peripheral surface of the operation knob in a state where the operation knob or the shaft is rotatably inserted into the reference hole. A substantially uniform clearance can be formed over the entire circumference between the rib and the rib.

In this case, since the operation knob is supported rotatably with respect to the reference hole, if both the rib and the reference hole are formed in the light guide member, the outer peripheral surface of the operation knob and the operation panel are formed. The dimensions of the light guide member and the ribs that appear can be made uniform over the entire circumference.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 shows an embodiment of the operating device of the present invention, and is a partial cross-sectional view showing a separated state of each member, FIG. 2 is a cross-sectional view showing a state where each member of FIG. 1 is assembled, and FIG. FIG. 4 is a front view showing a member and a movable member, and FIG. 4 is a partial sectional view showing another embodiment. The operating device shown in FIG.
It is provided in a vehicle-mounted audio device, a navigation system, and the like. A mounting hole 11a is formed in the operation panel 11 of the electronic device. On the rear surface (Y2 side in the figure) of the operation panel 11, a column 13, a light guide member 18, a rotary operation component 16, an adjustment mechanism A, and the like are provided. The adjusting mechanism A includes a support member 14, a movable member 19,
It is composed of a sleeve 20 and the like.

The operation panel 11 is formed of, for example, an ABS resin. At this time, the mounting holes 11a and the columns 13 are formed integrally with the operation panel 11. A step 13a having a convex cross section is formed at the tip of the column 13, and screw holes 13b, 13b are formed at the end face. The support member 14 is formed of, for example, a metal plate, and has a mounting hole 1.
4a, 14a, a through hole 14b, and a square through hole 14c are formed. The mounting hole 14a of the support member 14 is externally inserted into the step 13a of the support 13 and the support member 14 is fixed to the support 13 by screws 15,15.

On the Y2 side of the support member 14, a movable member 19 is provided. The movable member 19 is formed by stamping a thin metal plate as shown in FIG. 3, and has elasticity so that it can function as a leaf spring.
The movable member 19 has a hook at one end (X1 side) of the main body 19A. A bent portion 19 </ b> B exhibiting elasticity is formed by bending integrally with the hooking portion, and is inserted into a through-hole 14 c that functions as a rotation preventing portion formed in the support member 14. Also, the main body 19A adjacent to the bent portion 19B
, A convex portion 19b protruding toward the illustrated Y1 side is formed by pressure. The projection 19b is formed by, for example, punching, and has a very small height α1.

The main body 19A of the movable member 19 has a fixing hole 19 at a position overlapping with the through hole 14b of the support member 14.
a is drilled. The inner diameter W3 of the fixing hole 19a is formed to be smaller than the inner diameter W2 of the through hole 14b (W2> W3), and a rotary operation component 16 described later is inserted into the fixing hole 19a. A light guide member 18 is provided between the back surface of the operation panel 11 and the support member 14. On the Y1 side of the light guide member 18, the mounting hole 11a is provided.
A ring-shaped rib 18c having an outer diameter substantially the same as the inner diameter of the ring 18c is provided. The inside of the rib 18c of the light guide member 18 is a receiving portion 18b to which the operation knob 12 is attached. A reference hole 18a is formed in the center of the receiving portion 18b. In the assembled state shown in FIG. 2, the rotary operation component 16 and the operation knob 12 are attached with reference to the reference hole 18a.

As shown in FIG. 2, the rib 18c formed on the light guide member 18 is fitted into the mounting hole 11a of the operation panel 11 from the Y2 direction in the drawing, whereby the mounting hole 11a
Then, the receiving portion 18b and the rib 18c of the light guide member 18 and the reference hole 18a appear. The light guide member 18 is
For example, it is formed of a transparent resin such as acrylic, and is provided inside the operation panel 11 with a lamp or an LED.
When light from a light emitting member (not shown) such as a light transmitting member passes through the inside of the light guide member 18, the rib 18 around the operation knob 12 is turned on.
c is illuminated brightly.

As shown in FIG. 1, the rotary operation part 16 includes
An operation shaft 16c protrudes from the main body 16a.
A threaded portion 16b is provided around the root of c. Screw part 16
A thread groove is threaded on the outer peripheral surface of b, and a nut 17 can be screwed onto the thread groove. The rotary operation component 16 is inserted into the fixing hole 19 a of the movable member 19, and is also inserted into the through hole 14 b of the support member 14 and screwed by the nut 17. However, before the nut 17 is tightened, a sleeve 20 as shown in FIG. 1 is interposed. The sleeve 20 includes a cylindrical portion 20a and a flange portion 20b continuous with the cylindrical portion 20a.

As shown in FIGS. 1 and 2, the sleeve 2
0 of the cylindrical portion 20a is equal to the through hole 1 of the support member 14.
4b is smaller than the inner diameter W2 (W1 <W
2). The length (height in the Y-axis direction) h of the cylindrical portion 20a
Is formed longer than the thickness t1 of the support member 14 (h> t1), and a slight gap α2 is formed between the support member 14 and the movable member 19. With the sleeve 20 inserted into the through hole 14b of the support member 14, the threaded portion 16b of the rotary operation component 16 is inserted into the sleeve 20, and the bottom surface 20c contacts the movable member 19, The nut 17 is fastened to the threaded portion 16b, and the rotary operation component 16, the sleeve 20, and the nut 17 are fixed with the movable member 19 therebetween, as shown in FIG. In this state, the rotary operation component 16 is securely fixed to the movable member 19, but is not restrained at all by the support member 14.

The bent portion 19B of the movable member 19 is inserted into the above-described square through hole 14c. The difference in width in the Z direction between the square through hole 14c and the bent portion 19B in FIG. Is slight. However, in the movable member 19,
The portion apart from the bent portion 19B is the bent portion 19B
As a fulcrum, there is a rotation margin as shown by a broken line in FIG. The movable member 19 is movable in the X1-X2 direction with respect to the support member 14. Therefore, the rotary operation component 16 fixed to the movable member 19 can freely move in the direction orthogonal to the axial direction of the operation shaft 16c within the range of the difference between the diameter W1 of the sleeve 20 and the inner diameter W2 of the through hole 14b. You can move. Further, the movable member 19 functions as a leaf spring, and the distal end portion of the bent portion 19B is resiliently pressed by the support member 14, and the convex portion 19b is repressed by the support member 14. The left end side of the movable member 19 in the figure is urged in the counterclockwise direction with the convex portion 19b as a fulcrum, and the flange portion 20b of the sleeve 20 is pressed against the support member. Therefore, the rattling of the rotary operation component 16 in the axial direction is suppressed, so that rattle noise and the like can be dealt with.

For example, as shown in FIG.
By setting the height α1 of 9b sufficiently larger than the gap α2 between the support member 14 and the movable member 19, (α1>
α2), the rattling of the rotary operation component 16 can be suppressed without causing the bending portion 19B to resiliently press the support member 14. That is, the projection 19 b presses the back surface of the support member 14 to attach the rotary operation component 16 to the X.
Since the end of the movable member 19 on the second side is urged in the Y2 direction in the drawing, it is possible to prevent the rotational operation component 16 from being pressed by the support member 14 and causing rattling. Therefore, the bent portion 19B does not necessarily need to be provided to extend in the X1 direction beyond the through-hole 14c. The support member 1 of the movable member 19
Since the elastic pressure on 4 is weak due to the elasticity of the movable member 19 itself, it does not prevent the movable member 19 from moving in a direction orthogonal to the operation shaft 16c.

Further, as shown in FIG.
The operation shaft 16c is inserted into the reference hole 18a of the light guide member 18 and the mounting hole 11a (the rib 18) of the operation panel 11 is inserted.
Exposed in c). The operation knob 12 is mounted from the front (Y1 side) of the operation panel 11. At this time, the operation knob 1
The second shaft portion 12a is rotatably inserted into the reference hole 18a of the light guide member 18, and the operation shaft 16c of the rotary operation component 16 is fitted into the fitting hole 12c formed on the end face of the shaft portion 12a. Is done. In this state, the outer peripheral surface 12 at the base end of the operation knob 12 is
b faces the inner surface of the rib 18c of the light guide member 18. In FIG. 2, an outer peripheral surface 12b of a shaft portion 12a of the operation knob 12,
The gap between the reference hole 18a is indicated by S2, and the clearance between the outer peripheral surface 12b at the base end of the operation knob 12 and the inner peripheral surface of the rib 18c is indicated by S1. In FIG. 2, S1 and S2 are shown with the same dimensions, but in reality, S2 is sufficiently smaller than S1, and the shaft portion 12a is rotatably held with reference to the reference hole 18a. Therefore, the base outer peripheral surface 1 of the operation knob 12
The clearance S1 between 2b and the inner surface of the rib 18c can be made uniform on the outer periphery of the operation knob 12.

Also, as described above, the shaft 1 of the operation knob 12
2a is inserted into the reference hole 18a of the light guide member 18,
The rotary operation component 16 supported by the support member 14 is movable together with the movable member 19 with respect to the support member 14. Therefore, the operation shaft 16c of the rotary operation component 16 follows the operation knob 12 and is fitted into the fitting hole 12c. Therefore, even if there is an error in the mounting position of the support member 14 with respect to the operation panel 11, the operation knob 12 that is mounted based on the reference hole 18a and the rotary operation component 16 can be reliably connected. Further, when the operation knob 12 is rotated, the engaging portion of the movable member 19 is engaged with the through-hole 14 c of the support member 14, so that the movable member 19 and the rotary operation component 16 can freely move together with the operation knob 12. There is no rotation.

In the above description, the operation panel 11
Although only one operating device is shown in FIG. 1, it is needless to say that a case where a plurality of operating devices are provided can be handled. In this case, a plurality of mounting holes 11 a are formed in the operation panel 11, and a plurality of rotation operation parts 16 and a movable member 19 are attached to the support member 14. At this time, a pair of movable members 19 are hung in one through-square hole 14c, and the rotating operation parts 16 are attached to the opposite ends of the movable members 19, respectively, so that the operating device is installed in a smaller space. can do.

The operation knob 12 is supported so as to be always rotatable with respect to the operation panel 11 in an optimum state.
Further, as shown in FIG. 2, when the rib 18c of the light guide member 18 appears on the outer periphery of the operation knob 12, the operation knob 12 is mounted with reference to the reference hole 18a.
The ribs 18c of the light guide member 18 are uniformly distributed around the operation knob 12.
Is located, and the outer periphery of the operation knob 12 can be uniformly illuminated. Further, in the illustrated embodiment, the operation knob 12
Is rotatably held with a minimum gap with respect to the reference hole 18a of the light guide member 18.
The operation shaft 16c of the rotary operation component 16 may be rotatably held in the reference hole 18a of the light guide member 18 with a minimum gap.

[0034]

According to the present invention described in detail above, it is possible to correct the positional relationship between the operation knob attached to the operation panel and the rotary operation component. Therefore, the operation knob is always held in an optimal state (minimum clearance) by the operation panel, and the operation knob and the shaft of the rotary operation component are securely connected.
Therefore, when the light guide member appears on the outer periphery of the operation knob, the operation knob and the light guide member can be arranged concentrically, and the outer periphery of the operation knob can be uniformly illuminated. Further, when the movable member is configured to be resiliently pressed by the support member, it is possible to prevent rattling between the rotary operation component and the movable member.
