Description

  The present invention relates to an operating device.

  As an operation device, there is a device such as a pointing device capable of operating on a two-dimensional operation surface defined by an X axis and a Y axis direction orthogonal thereto. In such an operation device, an operation knob can be operated on a predetermined two-dimensional operation surface to indicate an arbitrary position, and further, the operation knob is pressed in the Z-axis direction orthogonal to the X-axis and the Y-axis. Thus, it is possible to perform position determination input for the designated position.

  In such an operation device, an operation knob is provided at the swing tip of a swing lever that swings along a spherical locus. For this reason, there is a problem that if the pressing operation in the Z-axis direction is performed at a position where the tilt angle of the swing lever is large, the indicated position is easily shifted, and a determination input is made at a position different from the position where the determination input is desired. .

  As a technique for solving such a problem, as disclosed in Patent Document 1, an X slider that slides the operation knob in parallel in the X-axis direction between the operation knob and the swing lever, and the operation knob together with the X slider are moved to the Y-axis. There is a technique of interposing a Y-slider that slides parallel to the direction. In this case, the X slider and the Y slider stacked on the rocking lever in the Z-axis direction slide on a spherical surface or a plane having a diameter larger than that of the rocking lever. When the pressing operation is performed, positional deviation in the X-axis direction and the Y-axis direction is unlikely to occur.

Japanese Patent Application No. 2008-246263

  However, the above configuration including the X slider and the Y slider has the following problems. That is, the number of parts is large, the backlash due to accumulation of dimensional variations increases, and the number of parts is large, so that the number of assembling steps is large and the cost is high. Furthermore, the difference in mass and size between the X-axis direction and the Y-axis direction of the movable part that moves in response to an operation from the user causes a backlash and a difference in friction. There is a problem that a difference occurs in the feeling, and in particular, an operation feeling in a direction oblique to the X direction and the Y direction is deteriorated.

  In addition, the two parts of the X slider and Y slider are made into one part as an XY slider that can move on the two-dimensional operation surface, and the configuration is made to slide on the two-dimensional plane, thereby minimizing the increase in the number of parts. Although a method can also be considered, in this case, a new problem arises that the operation knob rotates around the Z axis as the operation knob is moved in a two-dimensional direction. That is, if the operation knob has a simple design that is circular with a single color, there is no problem even if the operation knob rotates, since the user cannot see it, but the surface of the rectangular operation knob or operation knob As an operation knob with higher design, such as a pattern is drawn, is adopted, the appearance and the orientation of the design become more prominent due to the rotation of the operation knob accompanying the operation, and the design is deteriorated.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an operating device that reduces the number of parts for improving operational feeling and cost, and that does not change the attitude of the operating knob when operating the operating knob.

Means for Solving the Problems and Effects of the Invention

  In order to solve the above-described problems, an operating device according to the present invention includes a first rotation mechanism that enables a swing lever to rotate around a predetermined Y axis, and an X axis that is perpendicular to the Y axis. A second rotation mechanism that enables the first rotation mechanism to rotate about the X axis so that the swing lever can rotate about the X axis, and the swing lever is non-rotated about its own lever axis. An operating device having a swinging mechanism to be supported and having a movable operating part attached to the swinging tip side of the swinging lever and capable of moving in a two-dimensional direction defined by the X-axis direction and the Y-axis direction. It is assumed.

  According to the premise configuration of the present invention, in the state where the lever axial direction of the swing lever (hereinafter referred to as the z-axis direction) is matched with the Z-axis direction, the direction that matches the X-axis direction of the swing lever is the x-axis direction, Similarly, when the direction that coincides with the Y-axis direction in the swing lever is determined as the y-axis direction, the swing lever is swung in each direction, and the movable operation unit is viewed from above the Z-axis. As indicated by the lines x and y, the direction of the rocking lever in the x-axis direction is constantly maintained in the X-axis direction, while the direction of the rocking lever in the y-axis direction is relative to the X-axis and Y-axis. When operated in an oblique direction, it rotates around the Z axis, deviating from the Y axis direction. Therefore, when the movable operation unit is attached to the swing lever and operated obliquely with respect to the X axis and the Y axis, when the movable operation unit is viewed from above the Z axis, the movable operation unit appears to rotate around the Z axis. As a result, the appearance of the movable operation unit and the direction of the design become slanted, which impairs the design.

Therefore, the operating device of the present invention is based on the above configuration,
An X-axis direction extending portion that extends to the X-axis direction side with respect to the lever axis direction, and a spherical surface having a spherical outer surface and a spherical center on the lever axis line, A rotation preventing portion having a portion, and
The movable operation part is formed with a sliding opening for slidably holding the rocking tip side of the rocking lever. The sliding opening has an X-axis extending part on the Y-axis. Y-axis direction opposing wall portions that are opposed in a manner sandwiched from both sides in the direction, and spherical surface holding wall portions that sandwich the spherical portion from both sides in the X-axis direction and both sides in the Y-axis direction are formed.
When the movable lever is operated in a two-dimensional direction and the swing lever swings, the X-axis extending portion of the swing lever always extends in the X-axis direction when viewed in the Z-axis direction. Rotating around the Z-axis that occurs in the spherical part of the swing lever during the swinging operation, while always restricting the rotation of the sliding opening in the movable operation portion around the Z-axis of the opposing wall in the Y-axis direction. Is absorbed by the rotational sliding of the spherical surface portion and the spherical surface holding wall portion of the sliding opening in the movable operation portion, so that the movement operation of the movable operation portion is a parallel movement with the posture always kept constant. It is made in the form.

  In the present invention, when the swing lever is swung in each direction and the movable operation unit is viewed from above the Z-axis, as indicated by the line x in FIG. Is made by paying attention to the fact that the direction always coincides with the X-axis direction. According to the configuration of the present invention, when the swing lever is swung in each direction, the x-axis direction of the swing lever is always aligned with the X-axis direction. The X-axis direction extending portion provided on the distal end side also always extends in the X-axis direction side, and the movable operation portion sandwiching the X-axis direction extending portion in the Y-axis direction extends in the X-axis direction. The rotation around the lever axis z is restricted by the portion, and as a result, the rotation of the movable operation portion around the lever axis z is prevented. On the other hand, in the y-axis direction of the swing lever, when the movable operation unit is operated obliquely with respect to the X-axis and the Y-axis, the Y-axis direction rotates around the Z-axis as indicated by the line y in FIG. It will deviate from the direction. However, since the movable operation part is provided so as to be rotatable and slidable relative to the spherical part provided on the swinging tip side of the swinging lever, the swinging lever can be rotated around the Z axis. It will not rotate. Accordingly, the posture of the movable operation unit does not rotate around the Z axis, and a parallel movement operation can be performed while maintaining the same posture.

  Further, according to the configuration of the present invention, since the X slider and the Y slider may be made into one component, the number of components can be reduced, the operation feeling can be improved, and the cost can be suppressed. Specifically, the sliding opening portion has a cylindrical opening shape that allows the displacement in the Z-axis direction accompanying the swinging motion of the X-axis extending portion and the spherical surface portion of the swinging lever that is slidably held. The movable operation part can be formed by the X-axis direction side and the Y-axis direction provided on the base member on the apparatus main body side so that the displacement in the Z-axis direction accompanying the swinging operation is absorbed by the sliding opening. It can be configured as an XY slider that can slide on a spherical sliding surface having a diameter larger than the swing radius of the swing lever that spreads to the side. As a result, the movable operation unit can be moved in contact with the spherical sliding surface. Note that the spherical sliding surface includes a flat surface perpendicular to the Z-axis direction in which the rocking radius of the rocking lever is infinite. Further, by adopting a configuration in which the movable operation unit and the spherical sliding surface are in surface contact, the rotation of the movable operation unit around the X axis and the Y axis can be restricted, and the attitude of the movable operation unit can be kept constant. Operation in a two-dimensional direction while maintaining this is possible.

  In the present invention, the movable operation unit is sandwiched by a guide member provided on the apparatus main body side and having a guide surface facing the base surface in the lever axial direction, and is in a two-dimensional direction along the spherical sliding surface. It can be configured to be guided so as to be able to move only. As a result, the movement of the movable operation unit that slides on the spherical sliding surface is guided in the up and down directions, so that the operation is stabilized and the operational stability is increased.

  In the present invention, a slight gap is taken into consideration between the swinging tip side of the swinging lever and the sliding opening of the movable operation unit that holds the swinging lever in consideration of manufacturing errors and assembly errors of each component. At this time, the movable operating portion has a backlash that urges the swinging tip side of the swinging lever disposed in the sliding opening against a part of the inner wall surface in the sliding opening. An urging member for prevention can be provided. Thereby, it becomes possible to prevent the play which arises by a clearance gap, and it can improve an operation feeling. In a configuration having a cylindrical opening that can allow displacement in the Z-axis direction associated with the swinging motion of the swing lever, the backlash prevention biasing member is located at the swing tip of the swing lever within the slide opening. By configuring so that a part of the inner wall surface is urged in a direction orthogonal to the Z-axis direction, displacement of the swing lever in the Z-axis direction is not hindered.

  In the present invention, the sliding opening portion of the movable operation portion can be formed to have an opening shape that allows the X-axis direction extending portion of the swinging lever to be slidably held and the Z-axis direction displacement of the spherical portion. According to this configuration, it is possible to absorb the displacement in the Z-axis direction of the movable operation unit due to the rocking displacement of the rocking lever, and it is possible to move the movable operation unit on a certain plane.

  Specifically, the sliding opening can be formed as a cylindrical opening having an axis in the Z-axis direction so that the displacement of the spherical portion in the Z-axis direction is allowed. Thereby, the spherical surface portion of the swing lever can be smoothly moved up and down in the Z-axis direction. In addition, the Y-axis opposing wall extends in the Z-axis direction and is connected to the cylindrical opening so that displacement in the Z-axis direction of the X-axis extending part is allowed in the sliding opening. A Y-axis direction opening extending in the direction can also be formed. By having the Y-axis direction opening connected to the cylindrical opening, the sliding opening of the movable operation unit can be formed more simply. In addition, the sliding opening can be formed with a Z-axis direction lower end opening that has a larger opening area on the lower side in the Z-axis direction than the spherical surface holding wall. As a result, interference between the swing lever that swings and the sliding opening can be eliminated.

  In the present invention, a Z-axis direction pressing operation mechanism capable of pressing the movable operation unit in the Z-axis direction can be provided. If the movable operation unit is configured to be able to perform a parallel operation on a two-dimensional plane, it is difficult to shift the indicated position when the movable operation unit is pressed in the Z-axis direction. In this case, the sliding opening portion can be formed with an opening shape that can allow displacement in the Z-axis direction accompanying the pressing operation of the X-axis direction extending portion and the spherical portion of the swinging lever that is slidably held. . More specifically, the sliding opening includes the maximum displacement in the Z-axis direction associated with the rocking motion of the X-axis extending portion and the spherical surface portion of the rocking lever that is slidably held, and the Z-axis direction associated with the pressing operation. It can be formed with an opening shape that allows both maximum displacements simultaneously.

  In the configuration including the base member, the Z-axis direction pressing operation mechanism is configured such that when the movable operation unit is pressed, the base member is displaced in the Z-axis direction together with the movable operation unit. When the movable operation unit is pressed, the base member that comes into contact with the movable operation unit is also pushed down, so that a more stable pressing operation can be performed. In this case, it is preferable to include an urging unit that applies an urging force in the opposite direction to the displacement caused by the pressing operation so that the movable operation unit and the base member can be automatically returned from the pressing operation.

  The operating device 1 shown in FIG. 1 includes a movable operating unit 2 on the device main body 3 that can be moved in a two-dimensional direction defined by an X axis that defines a predetermined direction and a Y axis that is orthogonal thereto. As shown in FIGS. 2 and 3, the apparatus main body 3 includes a swing lever 21, a swing mechanism 20 that supports the swing lever 21 so as to be swingable in the two-dimensional direction, and a swing mechanism 20. And a lower case 19 for housing the container.

  The operation device 1 here is an on-vehicle operation device mounted on a vehicle such as an automobile, and is movable above the gravity direction (here, the same direction as the Z-axis direction orthogonal to the Z-axis and the Y-axis). The operation unit 2 can be operated in the front-rear direction (Y-axis direction) and the left-right direction (X-axis direction) of the vehicle, and as shown in FIG. 14, a display provided separately according to the operation direction of the operation The position indicating image (pointer) P displayed on the screen 320a of the apparatus 320 is moved. Thereby, the operation image (button) B displayed on the screen 320a can be instructed, and further determined by pressing the movable operation unit 2 downward (Z-axis direction) at the instructed position. Input can be made.

  The movable operation unit 2 is attached to the rocking tip side of the rocking lever 21 and receives the operation in the two-dimensional direction from the user. Specifically, an operation knob 10 that receives a user operation, and an XY sliding portion (XY slider) 16 that is slidably arranged in a two-dimensional direction on a sliding receiving member 17 fixed to the apparatus main body 3 side. And a lever holding part 15 for holding the rocking tip of the rocking lever 21 and an operation lever 14 for connecting the lever holding part 15 and the operation knob 10 so that each of them is non-rotated around the Z axis. It is fixed to.

  The operation knob 10 has a shape in which a rotation change in appearance can be visually recognized when the operation knob 10 is rotated around the Z axis in a state where the movable operation unit 2 is disposed on the swing knob 21. As shown in the Z-axis direction view, it is formed in a substantially quadrangular shape in plan view with rounded corners formed at the corners. Below the operation knob 10 in the Z-axis direction, the operation lever 14 is fixed so as to be non-rotatably held around the Z-axis. Here, the upper end of the cylindrical operation lever 14 in the Z-axis direction is cut out so as to have a non-circular cross section (here, cut out so as to form a cross section D), and the back side of the operation knob 10 In addition, a fitting hole corresponding to the shape of the upper end portion in the Z-axis direction is provided, and the upper end portion in the Z-axis direction of the operation lever 14 and the fitting hole portion of the operation knob 10 are press-fitted and fitted. Both are fixed non-rotating around the Z axis.

  The XY sliding portion 16 has three or more projecting portions (here, four locations) 160 protruding downward in the Z-axis direction, and each is formed on the upper surface of the sliding receiving member (base member) 17 in the Z-axis direction. The sliding surface (base surface) 170b comes into contact with the sliding surface 170b and can slide on the sliding surface 170b. By forming the protrusion 160, the contact area with the slide surface 170b is reduced, and as a result, the sliding friction is reduced and the operation feeling is improved. The slide surface 170b here forms a spherical sliding surface (here, a flat surface with an infinite diameter) having a diameter larger than the rocking radius of the rocking lever 21 held by the lever holding portion 15. Further, as shown in FIG. 2, the slide surface 170 b is formed as a bottom surface of a recess that is formed on the top surface of the slide receiving member 17 in the Z-axis direction and is recessed downward in the Z-axis direction, and corresponds to each protrusion 160. The inner wall surface 17b of the recess is formed so that the sliding surface is partitioned, and the movement of each projection 160 outside the partition region is restricted.

  Further, the XY sliding portion 16 is prevented from being pulled upward in the Z-axis direction and rotating around the X-axis and the Y-axis by the upper case 12. Here, the XY sliding portion 16 is slidably arranged with three or more contact points with respect to the sliding surface 170b, and thus the movable operation portion 2 can be rotated around the X axis and the Y axis. Is prevented. More specifically, the XY sliding portion 16 has four contact portions 160 that are formed so as to protrude downward from the lower corner portion of the Z-axis direction in the Z-axis direction, and these are in surface contact with the slide surface 170b. It is slidably arranged. On the other hand, the upper case 12 fixed to the apparatus main body 3 side has a guide surface 12a facing the slide surface 170b in the Z-axis direction, and the sliding movement of the movable operation unit 2 is performed on the slide surface 170b. It functions as a guide member that guides only in the two-dimensional direction along. The upper case 12 is fixed to the sliding receiving member 17 (here, fastening and fixing by a fastening member 12e such as a screw), and both of them constitute a part of the apparatus main body 3.

  The movable operation unit 2 includes an upper end opening 12c in which the XY sliding unit 16 and the lever holding unit 15 are accommodated in the upper case 12, and the operation lever 14 is formed above the upper case 12 in the Z-axis direction. It is arranged in a form protruding from. The upper end opening 12c is covered with an opening protection covering member 11 fixed to the operation lever 14 on the lower side of the operation knob 10 in the Z-axis direction. The covering member 11 is integrally attached to the operation lever 14 so as not to rotate about the Z axis, and forms a part of the movable operation unit 2. Further, the upper case 12 and the covering member 11 are also covered with a palm rest 200 that forms an outer cover, and the operation lever 14 protrudes from the opening at the upper end in the Z-axis direction of the palm rest 200 and the operation knob 10 is exposed. The palm rest 200 is fixed to the lower cover 19 (fastening and fixing with a fastening member such as a screw).

  The lower cover 19 accommodates the swing mechanism 20, and the swing lever 21 protrudes upward in the Z-axis direction. An opening 20c for projecting the swing lever 21 is formed on the upper surface portion 20a of the lower cover 19, and a determination for performing a determination input at the position indicated by the movable operation portion 2 is provided on the upper surface portion 20a. A switch support member 18 provided with an input switch 182 is placed. The switch support member 18 is a plate-like member having an opening 18c for projecting the swing lever 21 at the center. The decision input switch 182 is a tact switch, and a plurality of the decision input switches 182 are provided around the center of the opening 18c, and are arranged so as to be pressed from above the Z axis. Here, the pressing operation receiving member 181 is provided at three positions around the center of the opening 18c every 90 degrees, and at the remaining one position, the pressing operation receiving member 181 that only receives the pressing operation from above the Z-axis is provided. The slide receiving member 17 is arranged on the upper side of the switch support member 18 in the Z-axis direction. A lower end portion of the slide receiving member 17 projects downward from the Z-axis in order to press the determination input switch 182 on the switch support member 18. A pressing portion 170 is provided. When the movable operation portion 2 is pressed downward in the Z-axis direction, the XY sliding portion 16 presses the slide receiving member (base member) 17, thereby causing the slide receiving member 17 together with the movable operating portion 2 to move. By displacing in the Z-axis direction (Z-axis direction pressing operation mechanism), the pressing unit 170 presses the decision input switch 182. Further, here, a spring member (biasing means) 20B for applying an urging force in the opposite direction to the displacement caused by the pressing operation is provided at the oscillating center portion 20A of the oscillating lever 21, and the pressing operation is released. Then, the movable operation portion 2 and the slide receiving member 17 are automatically returned to the positions at the time of the non-pressing operation by the biasing force of the spring member. Here, a spring member (biasing means) that applies an urging force in the opposite direction to the displacement caused by the pressing operation may be provided in the tact switch 182.

  On the other hand, the swing mechanism 20 that swingably supports the swing lever 21 includes a first swing mechanism 30 that allows the swing lever 21 to rotate around a predetermined X axis, and the swing lever 21. A second rotation mechanism 35 that can rotate about the Y axis together with the first rotation mechanism 30 to be held, and a z axis that holds the swing lever 21 so that it does not rotate about its own lever axis (z axis). And a rotation control mechanism. The swing mechanism 20 here is a gimbal mechanism as shown in FIG.

  Specifically, the first rotation mechanism 30 is swung by the first rotation shaft portion 29 that is rotatably supported by the first rotation support portion 31 so as to have a rotation axis in the X-axis direction. The lever 21 can be swung around the rotation axis. The rotation support part 31 here has X-axis direction opposing plate parts 31a and 31a that sandwich the rocking lever 21 so as to face the X-axis direction. Both the X-axis direction opposing plate portions 31a and 31a and the swing lever 21 are provided with through-hole portions 31h and 23h penetrating in the X-axis direction. A rotating shaft portion 29 is disposed. A head portion having a diameter larger than that of the through-hole portion 31h is provided at an end portion on the first side in the axial direction of the rotation shaft portion 29, and this is provided as one through-hole of the X-axis direction opposing plate portions 31a and 31a. On the second side, a slip-off preventing member 28 such as a C-ring is attached to the outer side of the other X-axis direction opposing plate portion 31a, and the rotation shaft is inserted through the second side. The part 29 is prevented from coming off.

  In this way, the swing lever 21 is held so as to be rotatable around the axis of the rotary shaft portion 29 disposed therethrough. However, the oscillating lever 21 does not oscillate and rotate around the X axis together with the rotation support portion 31 and is sandwiched in the X axis direction between the X axis direction opposing plate portions 31a and 31a forming the rotation support portion 31. Thus, the guide is guided so as to be swingable only in the Y-axis direction. Further, the through-hole portion forming portion 23 in which the through-hole portion 23 h is formed in the swing lever 21 has a shape in surface contact with the rotation support portion 31. Thereby, the rotation of the swing lever 21 around the Y axis and the Z axis with respect to the rotation support portion 31 is restricted.

  On the other hand, the second rotation mechanism 35 is provided by a second rotation shaft portion 39 that is rotatably supported by a second rotation support portion 191 that is fixed to the apparatus main body side so as to have a rotation axis in the Y-axis direction. The first rotation mechanism 30 can be rotated around the rotation axis, and the swing lever 21 can be swung around the rotation axis. Here, the rotation support portion 191 is frames 191 and 191 facing each other fixed (fastened and fixed) to the lower case 19, in order to penetrate the cylindrical rotation shaft portion 39 extending linearly therethrough. Through-hole portions 191h and 191h are provided. A removal preventing member 38 such as a C-ring is attached to the projecting tip side of the rotation shaft portion 39 to prevent the rotation shaft portion 39 from coming off. The rotation shaft portion 39 supported by the frames 191 and 191 is restricted from rotating around the X axis and the Z axis with respect to the frames 191 and 191.

  In this case, when the swing lever 21 swings around the Y axis, the swing lever 21 is displaced in the X axis direction, so the first rotation support portion 31 that sandwiches the swing lever 21 from both sides in the X axis direction. (One of the X-axis direction opposing plate portions 31a, 31a) is pressed in the swing direction (X-axis direction). Thereby, the swing lever 21 swings itself around the Y axis together with the first rotation support portion 31.

  Further, the second rotation shaft portion 39 has an axis line in the Y-axis direction orthogonal to the rotation axis line (X-axis direction) of the first rotation shaft portion 29, and from both ends of the rotation support portion 31 in the Y-axis direction. Projected in the Y-axis direction. More specifically, the first rotation support portion 31 protrudes outward in the Y-axis direction from the upper ends of the Y-axis facing plate portions 32, 32 provided at both ends of the X-axis facing plate portions 31a, 31a. To do. The Y axis direction opposing plate portions 32, 32 are the bases of the second rotary shaft portions 39, 39, and are opposed to each other in the Y axis direction at both ends outside the X axis direction opposing plate portions 31a, 31a. The direction opposing plate portions 31a and 31a are fixed integrally. Also, a gimbal gear 33 (described later) is integrally fixed to one of the Y-axis direction opposing plate portions 32, 32, and a reference position detection member 34 (described later) is integrally fixed to the other (both are screws here). Etc.). The rotary body 30 around the Y axis is configured to include the second rotary shaft portion 39, the first rotary support portion 31 (31a, 32), the base portion 32, the gimbal gear 33, and the reference position detection member 34. .

  In such a rocking mechanism (gimbal mechanism) 20, the rocking lever 21 rotates around the X axis on a rotating coordinate system that rotates around the Y axis. That is, the second rotation support portion 191 that supports the second rotation shaft portion 39 so as to be rotatable in the Y-axis direction is fixed to the apparatus main body in the form of a base, and the first rotation support portion 31. Is pivotably supported only around the Y axis, and the rocking lever 21 is pivotable around the Y axis together with the pivot support portion 31 by causing the rocking displacement only in the X axis direction (X axis direction). Can be swung). On the other hand, the first rotation shaft portion 29 attached to the first rotation support portion 31 that can be rotated around the Y axis is supported by the first rotation shaft portion 29 so as to be rotatable around the X axis. 21 can be swung around the X axis. Further, the swing lever 21 is restricted from rotating around the Z-axis with respect to the rotation support portion 31 by the through-hole portion forming portion 23 and the rotation support portion 31, and the rotation support portion 31 includes the rotation shaft portion 39 and the frame. 191 and 191 restrict the rotation around the Z-axis with respect to the apparatus main body 3. These constitute a rotation restriction mechanism around the z-axis to prevent the swing lever 21 from rotating around the Z-axis with respect to the apparatus main body 3. Yes.

  However, in a state in which the lever axis direction of the swing lever 21 (hereinafter referred to as the z-axis direction) coincides with the Z-axis direction, the direction that coincides with the X-axis direction of the swing lever 21 is the x-axis direction. 21, when the direction that coincides with the Y-axis direction is determined as the y-axis direction, the swing lever 21 is swung in each direction, and the swing tip of the swing lever 21 is viewed from above in the Z-axis direction. As shown by the x-axis and y-axis in FIG. 17, the orientation of the swing lever 21 in the x-axis direction is constantly maintained in the X-axis direction, while the orientation of the swing lever 21 in the y-axis direction is the X-axis and When operated in an oblique direction with respect to the Y axis, the position is shifted from the Y axis direction and rotated around the Z axis. As a specific example, FIG. 18 shows calculation results when XY coordinates as shown in FIG. 17 are determined and the swing lever 21 is rotated 16 ° around the X axis and 16 ° around the Y axis. According to this result, the Y component in the AB direction before rotation and the A ″ B ″ direction after rotation in both XY directions is zero, the x-axis direction remains constant, and the y-axis direction does not rotate. It turns out that rotation has arisen.

  As described above, the swing lever 21 is normally attached to the swing lever 21 with the movable operating unit 2 on the rotational coordinate system that rotates about the Y axis. When the movable operation unit 2 is operated obliquely with respect to the Y axis, the movable operation unit 2 appears to rotate around the Z axis when viewed from above the Z axis. As shown in FIG. 3, the movable operation unit 2 here has a shape in which the rotation change of the appearance can be visually recognized when the operation knob 10 rotates around the Z axis. Since it is visually recognized, there is a possibility of deteriorating the design. For this reason, in the present invention, in order to prevent such rotation of the movable operation unit 2 around the Z axis, the movable operation unit 2 and the swing lever 21 have the following mounting structure.

  That is, as schematically shown in FIGS. 11 and 12, the rotation preventing portion 100 is provided on the swinging tip side of the swinging lever 21 (here, the swinging tip portion). The rotation prevention unit 100 includes an X-axis direction extending portion 102 extending to the X-axis direction side with respect to the lever axis line z direction, and a spherical surface portion 101 having an outer peripheral surface having a spherical shape and a spherical center on the lever axis line z. And have. On the other hand, the movable operation part 2 is formed with a sliding opening 150 that holds the swinging tip side of the swinging lever 21 so as to be slidable inside. This sliding opening 150 restricts the rotation around the Z axis and allows the displacement in the X axis direction so as to oppose the X axis extending portion 102 from both sides in the Y axis direction. Opposite wall portions 152a and 152a, and spherical portion holding wall portions 151a and 151a that hold the spherical portion 101 from both sides in the X-axis direction and both sides in the Y-axis direction so as to be able to rotate and slide.

  Further, the sliding opening 150 here has a cylindrical opening shape that allows the X-axis direction extending portion 102 and the spherical surface portion 101 of the swinging lever 21 to slide and hold to be displaced in the Z-axis direction. More specifically, a cylindrical opening 151 having a cylindrical inner wall surface having an axis in the Z-axis direction so that the spherical portion 101 can be displaced in the Z-axis direction, and an X-axis extending portion 102. The X-axis direction opening 152 is formed so as to extend in the X-axis direction so as to be connected to the cylindrical opening 151 so that the Z-axis direction displacement is allowed, and the Z-axis direction lower end side of the cylindrical opening 151 The lower side in the Z-axis direction does not interfere with the two-dimensional swinging motion of the swing lever 21 centered on the spherical portion 101 that occurs in the swing lever 21 held in the cylindrical opening 151. And a Z-axis direction lower end opening 153 formed so as to increase the opening area.

  Here, the operation of the swing lever 21 and the movable operation unit 2 will be specifically described.

  When the swing lever 21 is swung around the Y axis from the neutral position (see FIG. 18E) (see FIG. 18B or FIG. 18H), the x-axis direction of the swing lever 21 itself is In the Z-axis direction view, it always coincides with the X-axis direction, and the y-axis direction of the swing lever 21 itself always coincides with the Y-axis direction in the Z-axis direction view. Therefore, when the swing operation occurs, the spherical surface portion 101 of the swing lever 21 presses the inner wall surface on the X-axis direction side in the cylindrical opening 151 of the movable operation portion 2 in the X-axis direction. Thus, the inside of the cylindrical opening 151 rotates and slides around the Y axis, and the movable operation unit 2 is displaced in the X-axis direction, while the movable operation unit is slid on the inner wall surface in the cylindrical opening 151. 2 is also displaced in the Z-axis direction. Similarly to the spherical surface portion 101, the X-axis direction extension portion 102 of the swing lever 21 rotates in the X-axis direction opening portion 152 of the movable operation portion 2 around the Y-axis, and the Z-axis direction and the Z-axis direction. Displace in the direction. However, since the movable operation unit 2 is always held slidably mounted on the slide surface 170a, the spherical portion 101 and the X-axis extending portion 102 of the swing lever 21 are in the Z-axis direction. Even if the displacement occurs, the displacement does not follow the Z-axis direction, and the spherical surface portion 101 and the X-axis direction extension portion 102 slide along the inner wall surface in the sliding opening 150 in the Z-axis direction. By moving, the displacement of the spherical surface portion 101 and the X-axis direction extension portion 102 in the Z-axis direction is absorbed, and its own Z-axis direction position is held at a fixed position in contact with the slide surface 170a.

  When the swing lever 21 is swung around the X axis from the neutral position (see FIG. 18E) (see FIG. 18D or FIG. 18F), the x-axis direction of the swing lever 21 itself is The y-axis direction of the swing lever 21 itself coincides with the Y-axis direction when viewed in the Z-axis direction. Therefore, when the swing operation occurs, the spherical surface portion 101 of the swing lever 21 presses the inner wall surface on the Y axis direction side in the cylindrical opening 151 in the movable operation portion 2 in the Y axis direction. In the cylindrical opening 151, the movable operating part is rotated and slid around the Y-axis, and the movable operating part 2 is displaced in the Y-axis direction, while the movable operating part is slid on the inner wall surface in the cylindrical opening 151. 2 is also displaced in the Z-axis direction. Similarly to the spherical surface portion 101, the X-axis direction extension portion 102 of the swing lever 21 also presses the inner wall surface on the Y-axis direction side in the X-axis direction opening 152 in the movable operation portion 2 in the Y-axis direction. The X-axis direction opening 152 is displaced in the Y-axis direction and the Z-axis direction so as to rotate and slide around the Y-axis. However, since the movable operation unit 2 is always held slidably mounted on the slide surface 170a, the spherical portion 101 and the X-axis extending portion 102 of the swing lever 21 are in the Z-axis direction. Even if the displacement occurs, the displacement does not follow the Z-axis direction, and the spherical surface portion 101 and the X-axis direction extension portion 102 slide along the inner wall surface in the sliding opening 150 in the Z-axis direction. By moving, the displacement of the spherical surface portion 101 and the X-axis direction extension portion 102 in the Z-axis direction is absorbed, and its own Z-axis direction position is held at a fixed position in contact with the slide surface 170a.

  When the swing lever 21 is swung from the neutral position (see FIG. 18 (e)) to both the X axis and the Y axis (FIGS. 18 (a), (c), (g), (i )), The x-axis direction of the swing lever 21 itself coincides with the X-axis direction when viewed in the Z-axis direction, but the y-axis direction of the swing lever 21 rotates around the Z-axis when viewed in the Z-axis direction. . Therefore, when the swing operation occurs, the spherical surface portion 101 of the swing lever 21 has both the X-axis direction side surface and the Y-axis direction side wall surface in the cylindrical opening 151 of the slide opening 150. In the form of pressing both in the X-axis direction and the Y-axis direction, the inside of the cylindrical opening 151 is rotated and slid around both the X-axis and the Y-axis. While displacing in the diagonal direction between both directions, it is also displaced in the Z-axis direction by sliding on the inner wall surface in the cylindrical opening 151. Similarly to the spherical surface portion 101, the X-axis direction extension portion 102 of the swing lever 21 also presses the inner wall surface on the Y-axis direction side in the X-axis direction opening 152 in the movable operation portion 2 in the Y-axis direction. The X-axis direction opening 152 is displaced in the oblique direction and the Z-axis direction so as to rotate and slide both around the Y-axis and around the X-axis. However, since the movable operation unit 2 is always held slidably mounted on the slide surface 170a, the spherical portion 101 and the X-axis extending portion 102 of the swing lever 21 are in the Z-axis direction. Even if a displacement occurs, it does not move in the Z-axis direction following this, and the spherical surface portion 101 and the X-axis direction extending portion 102 are slid along the inner wall surface in the sliding opening 150 in the Z-axis direction. By moving, the displacement of the spherical surface portion 101 and the X-axis direction extension portion 102 in the Z-axis direction is absorbed, and its own Z-axis direction position is held at a fixed position in contact with the slide surface 170a. Further, the y-axis direction of the swing lever 21 itself is rotated from the Y-axis direction around the Z-axis when viewed in the Z-axis direction, but the movable operation unit 2 does not rotate and follow this, Since the spherical surface portion 101 of the swing lever 21 rotates and slides in the cylindrical opening portion 151 in the sliding opening portion 150, it rotates relative to the movable operation portion 2. It is continuously held in a fixed posture in contact with the slide surface 170a.

  In this way, when the movable operation unit 2 is operated in a two-dimensional direction and the swing lever 21 swings accordingly, the x-axis direction of the swing lever 21 itself is the X-axis direction when viewed in the Z-axis direction. Since they always coincide with each other, the X-axis direction extending portion 102 of the swing lever 21 always protrudes in the X-axis direction when viewed in the Z-axis direction. For this reason, since the Y-axis direction opposing wall portions 152a and 152a of the movable operation unit 2 are always kept in a state of sandwiching the X-axis direction extension portion 102, the movable operation unit 2 does not rotate around the Z axis. . Further, the swinging movement of the swing lever 21 may cause the spherical portion 101 of the swing lever 21 to rotate such that its own y-axis direction is rotationally displaced about the Z-axis when viewed in the Z-axis direction. This rotation is absorbed when the spherical portion 101 of the swing lever 21 rotates and slides in the spherical portion holding wall portions 151a and 151a of the movable operation portion 2, thereby changing the posture of the movable operation portion 2. Nor. Further, the rotation preventing portion 100 provided on the swinging tip side of the swing lever 21 can be relatively displaced in the Z-axis direction with respect to the movable operation portion. Even if the moving tip side is displaced in the Z-axis direction, the movable operation unit 2 is held in contact with the slide surface 170a and does not change its posture. Therefore, the movable operation unit 2 can be operated in parallel in a two-dimensional direction. When operated, the appearance and the design direction of the operation knob 10 are inclined, and the design is not impaired.

  Here, as shown in FIG. 12 (b), there is a slight difference between the swing lever 21 and the sliding opening 150 of the movable operation unit 2 in consideration of manufacturing errors and assembly errors of each part. Although there is a gap, rattling due to this gap may occur if this is left as it is, so that the rocking lever 21 and the inner wall surface of the sliding opening 150 are always kept in contact with each other. A prevention urging member 13 is provided. Here, an opening 130 for biasing member arrangement formed so as to be connected to the sliding opening 150 is formed, and the center of the opening 130 is directed in the lever axis z direction of the swing lever 21. The leaf spring protruding in this manner is provided as the backlash preventing urging member 13 and continuously urges the swing lever 21 in the direction orthogonal to the Z-axis direction (here, the Y-axis direction). More specifically, as shown in FIG. 11, the opening 130 penetrates the movable operation unit 10 (here, the lever holding unit 15) in the Z-axis direction, and the backlash preventing urging member 13 is rocked. The movable operating portion 10 in a state where the moving lever 21 is held can be easily assembled by being inserted into the opening 130 from above in the Z-axis direction.

  Further, in the sliding opening 150 in the movable operation unit 2, the cylindrical opening 151 that holds the spherical portion 101 on the rocking tip side of the rocking lever 21 so as to be capable of rotating and sliding has an axis in the Z-axis direction. The stroke in the Z-axis direction is the maximum displacement in the Z-axis direction accompanying the swinging motion of the swing lever 21 and the maximum in the Z-axis direction for pressing the decision input switch 182 to the deepest part. Even when both displacements occur at the same time, the spherical portion 101 of the swing lever 21 is formed with such a length as to be sandwiched from both sides in the X-axis direction and both sides in the Y-axis direction. With this stroke secured, a Z-shaped opening having a truncated cone shape is formed on the lower side in the Z-axis direction so as not to interfere with the two-dimensional swing operation of the swing lever 21 having the spherical portion 101 as the swing center. An axial lower end opening 153 is formed.

  The swing mechanism 20 is provided with a swing member 40 that swings integrally with the first rotation mechanism 30. The oscillating member 40 allows the oscillating displacement around the axis of the second rotating shaft 39 of the oscillating lever 21 (around the Y axis), and around the axis of the first rotating shaft 29 together with the oscillating lever 21. Is fixed to the apparatus main body 3 so as to be rotatable. Specifically, the rocking member 40 includes a third rotation shaft portion 49 and a third rotation shaft portion 49 having an axis line that coincides with the rotation axis line of the first rotation shaft portion 29, and X A pivot support 192 that pivots around the shaft and the swing lever 21 are held in such a manner as to allow swing displacement about the axis of the second rotary shaft 39, while the first of the swing lever 21 is held. And a lever holding portion 41 that swings around the axis of the rotating shaft 49 by the swinging motion of the one rotating shaft 29 around the axis. The lever holding portion 41 is formed with a through-hole portion 41 h that penetrates the lower end portion 22 of the swing lever 21 in the Z-axis direction. The stepped portion 22d provided in 21 is arranged so as to abut. The through-hole portion 41h is formed long in the axial direction (X-axis direction) of the second rotating shaft portion 39, and the lever lower end portion 22 disposed through the longitudinal direction of the through-hole portion 41h (X-axis direction). It can slide along. The rotation support portions 192 are frames 192 and 192 that are fixed (fastened and fixed) to the lower case 19 and face each other, and are provided with through-hole portions 192h for penetrating the third rotation shaft portion 49, respectively. It is done.

  As a result, the rocking member 40 is pressed by the inner wall surface of the through hole 41h where the lever lower end 22 of the rocking lever 21 opposes the Y-axis direction as the rocking lever 21 swings around the X axis. As a result, it rotates about the X axis and swings and displaces in the Y-axis direction. On the other hand, when the swing lever 21 swings around the Y axis, the swing lever 21 moves in the through hole 41h in the Y axis. By simply sliding in the direction, the swing member 40 itself is not displaced.

  The gimbal gear 33 and the center detection member 34 are fixed integrally with the base portions 32 and 32 of the second rotary shaft portion 39 (here, fastened and fixed by a fastening member such as a screw). Swing around the axis. On the other hand, the gimbal gear 43 and the center detection member 44 also extend from the X axis direction both ends of the lever holding portion 41 that extends in the X axis direction in the rotation shaft portion 40 of the third rotation shaft portion 39. It is integrally fixed to the base portions 42 and 42 (here, fastened and fixed by a fastening member such as a screw) and swings around the axis of the third rotating shaft portion 39. The rocking body 40 around the X axis is configured to have a third rotating shaft portion 49, a lever holding portion 41, a base portion 42, a gimbal gear 43, and a reference position detecting member 44.

  By the way, the operation device 1 of the present embodiment is configured such that the movable operation unit 2 can move in the two-dimensional direction in the manner described above, and the operation reaction force against the movement operation in the two-dimensional direction. And an operation reaction force transmitting means 70 for transmitting the operation reaction force applied by the operation reaction force applying means 50 to the movable operation unit 2. Furthermore, an operation amount detection means 60 for detecting an operation amount to the operation knob 10 (movable operation unit 2) such as a movement direction and a movement amount of a two-dimensional movement operation to the movable operation unit 2 is provided. The operation reaction force applying means 50, the operation reaction force transmitting means 70, and the movement detection means 60 are disposed inside the apparatus main body 3 (in this case, the lower case 19).

  Here, the operation reaction force transmission means 70 is the gimbal gears 33 and 43 provided in the swing mechanism 20. The gimbal gears 33 and 43 are fixed so as to swing together with the second rotating mechanism 35 and the swinging member 40 that swings together with the first rotating mechanism 30. A rack portion is formed on the free end side opposite to the swing center of the gimbal gears 33, 43, and each rack portion has tooth portions 33g, 43g along a rotation locus around the corresponding rotation shaft portions 39, 49. Is formed. The gears 51X are attached to the rotation output shafts 50Xa and 50Ya of the actuators (motors) 50X and 50Y constituting the operation reaction force applying means 50 by the teeth 33g and 43g provided at the swinging tip. , 51Y (the reference numeral 51Y is not shown, but is attached to the rotation output shaft 50Ya in the same manner as the gear 51X). The actuators 50X and 50Y give a rotational driving force to the rotation output shafts 50Xa and 50Ya, and the gears 51X and 51Y (and further, as the movable operation unit 2 is moved and operated in a two-dimensional direction). An operation reaction force is applied that prevents or promotes the rotation operation transmitted to the rotation output shaft portions 50Xa and 50Ya). The actuators 50X and 50Y are driven and controlled by the control unit 300, and apply an operation reaction force according to the screen indication status of the position indication image P to the rotation output shaft portions 50Xa and 50Ya.

  Further, potentiometers 60X and 60Y for outputting detection signals indicating the respective rotation amounts are attached to the rotation output shaft portions 50Xa and 50Ya. As the movable operation unit 2 moves in the two-dimensional direction, the gimbal gears 33 and 43 swing around the axes of the rotary shafts 39 and 49 in the second rotation mechanism 35 and the swing member 40, and swing motion thereof. Is converted into the rotational motion of the corresponding rotation output shaft portions 50Xa, 50Ya, the rotation amount of each rotation output shaft portion 50Xa, 50Ya depends on the swing direction and swing amount of the gimbal gears 33, 43, and hence the movable operation portion. The movement position information of is reflected. The movement detection unit 60 is a potentiometer 60 that detects the rotation amount, and inputs a detection signal indicating the rotation amount to the control unit 300. The control unit 300 calculates the amount of displacement of the movable operation unit 2 from the input detection signal, and moves the position instruction image (pointer) P displayed on the screen 320a of the display device 320 according to this. That is, the control unit 300 functions as an indicated position detection unit that calculates the indicated position on the two-dimensional operation surface of the movable operation unit 2 based on the swing rotation amount of the gimbal gears 33 and 43. Here, the potentiometer 60 may be incorporated in the gears 51X and 51Y (potentiometer gear), or may be attached to the rotation output shaft portions 50Xa and 50Ya of the motors 50X and 50Y constituting the actuator so as to be integrally rotatable. Good.

  Reference position detecting means 61X and 61Y for detecting the reference positions of the potentiometers 60X and 60Y are also provided. Here, the light emitting unit and the light receiving unit are opposed to each other with the swing locus of each of the reference position detecting members 34 and 44 interposed therebetween, and light output from the light emitting unit is blocked by the reference position detecting members 34 and 44. As the light receiving unit is not detected, the control unit 300 recognizes the reference position.

  As illustrated in FIG. 14, the control unit 300 includes a CPU, a ROM, a RAM, and the like, and includes an external storage device 310, a signal input unit 301 that captures a switch signal output from the determination switch 182, and the control unit 300.

The first and second motor drivers 302 and 304 are connected to a display driver 321 that drives the display device 320 in accordance with a display device drive signal output from the control unit 300.

  The external storage device 310 has a program for displaying the button B on the screen 320a of the display device 320, and detection signals from the potentiometer gears 51X and 51Y that are input in accordance with a two-dimensional movement operation of the operation knob 10. Based on the program, the program for calculating the display position of the pointer P, the program for moving the pointer P on the screen 60a based on the calculated display position of the pointer P, and the pointer P enters the button B displayed on the screen A program for driving and controlling the actuators 50X and 50Y so as to give a sense of moderation, and an actuator for giving a pulling force that prevents the pointer P located on the button B displayed on the screen from moving out of the button B On the button B displayed on the screen, the program for controlling the drive of 50X and 50Y, the decision switch H. 182 includes a variety of well-known operation programs in the pointing device, such as a program for executing control corresponding to the button B to which the operation input has been performed, and these are executed by the control unit 300. Is done.

  Although one embodiment of the present invention has been described above, this is merely an example, and the present invention is not limited to this, and the knowledge of those skilled in the art can be used without departing from the spirit of the claims. Various modifications based on this are possible. Hereinafter, an embodiment different from the above embodiment will be described.

And a second rotating mechanism that allows the first rotating mechanism to rotate about the X axis so that the first rotating mechanism can rotate about the X axis. Other swing mechanisms may be employed as long as they are supported in a rotating form.

  For example, the present invention can be applied to a gimbal mechanism disclosed in Japanese Patent Application Laid-Open No. 2003-308127 and a spherical bearing type joystick mechanism as illustrated in FIG. In the case of FIG. 15, both the lever groove 402h formed in the X-axis direction in the X-axis side drive link 402 and the lever groove 401h formed in the Y-axis direction in the Y-axis side drive link 401 are both in the Z-axis direction. A rocking lever 421 is disposed so as to penetrate through. A plate portion 410 having flat surfaces 410 a and 410 a is provided at the lower end portion of the swing lever 421, and the swing lever 421 is brought into surface contact with the groove side surface 401 a of the lever groove 401 h of the Y-axis side drive link 401.

That is, in the swing mechanism 400 of FIG. 15, the swing lever 411 to which the movable operation unit 2 is attached is held by the Y-axis side drive link 401 in a non-rotating manner around its own lever axis line z. On the other hand, the swing lever 411 can be rotated around the X axis by the X-axis side drive link 402 without being particularly restricted from rotating around the lever axis z. Yes. As in the above-described embodiment, the rotation preventing portion 100 is provided on the rocking tip side of the rocking lever 21.

  In addition, the rotation prevention part 100 can comprise the whole operating device compactly by shortening the length of az axis line direction. For example, in the above embodiment, the rotation preventing unit 100 configured as shown in FIG. 16A may be cut out at the upper end in the z-axis direction of the spherical surface portion 101 as shown in FIG. (Here, cut out perpendicular to the z-axis: spherical portion 101 ′), as shown in FIG. 16C, not only the upper end of the spherical portion 101 in the z-axis direction but also the z-axis of the extending portion 102 in the X-axis direction. The upper end in the axial direction may also be cut out (here, cut out perpendicular to the z-axis: X-axis direction extending portion 102 ′). Only the upper end in the z-axis direction of the X-axis extending portion 102 may be cut out.
