  In recent years, with the diversification of various electronic devices, there has been an increasing demand for operation devices using magnets from the viewpoint of generating a strong operational feel and improving durability.

  As a conventional example of an operating device using this magnet, Patent Document 1 proposes a rotary operating device 916 that can provide a good moderation feel (click feeling). 16A and 16B are diagrams illustrating a conventional rotary operation device 916.

  However, in the configuration of the conventional example, the movable magnet 912 and the fixed magnet 915 are assembled at a predetermined interval, and the movable magnet 912 only rotates with respect to the fixed magnet 915. The request to change the operation feel could not be met. On the other hand, in addition to the method using a permanent magnet as in the conventional example, the operation feeling can be made variable by using an electromagnet. However, not only the configuration of the apparatus becomes complicated, but also it is necessary to continuously energize the electromagnet in order to keep the operation member at a predetermined position after the operation, which increases power consumption. There was a problem.

  The present invention solves the above-described problems, and an object of the present invention is to provide an operation feeling variable operation device that has a click feeling and can change the operation feeling.

In order to solve this problem, an operation feeling variable operation device is disposed on the operation member side, an operation member that can be operated by an operator, a support member that movably supports the operation member, and An operation feeling variable operation device comprising a first magnet and a second magnet disposed to face the first magnet, wherein the first magnet and the second magnet generate an operation feeling. Thus, at least one of the first magnet and the second magnet is magnetized with different magnetic poles alternately adjacent to each other at a predetermined interval, and the first magnet and the second magnet are opposed to each other. Magnetic force changing means for changing the area of the projection surface, and the magnetic force changing means relatively moves the first magnet and the second magnet in a vertical direction substantially perpendicular to the moving direction of the operation member. the moved by changing the area of the orthogonal projection plane, in proportion to the area, before Is characterized by gradual varying the magnetic force generated between the first magnet second magnet.

  According to this, the operation feeling variable operation device of the present invention can increase the magnetic force to increase the operation feeling and reduce the magnetic force to decrease the operation feeling. For this reason, the operation feeling generated with respect to the operator can be varied according to the use situation. In addition, the first magnet moves with the movement of the operation member, and the magnetic force between the first magnet and the second magnet is attracted or repelled. For this reason, a good click feeling can be given to the operator at a predetermined interval. Therefore, it is possible to provide an operation feeling variable operation device that has a click feeling and can change the operation feeling.

  According to this, it is possible to gradually change the magnetic force in proportion to the area of the orthogonal orthogonal projecting surface. This makes it possible to set a fine magnetic force. Furthermore, for example, compared with a case where the magnetic force generated between the first magnet and the second magnet is changed by changing the distance between the first magnet and the second magnet (when the magnetic force is changed in inverse proportion to the square of the distance). Thus, it is possible to easily create a change in magnetic force, and it is possible to finely vary the operation feeling generated for the operator according to the usage situation.

  According to this, the area of the orthogonal projection surface where the first magnet disposed on the operation member side and the second magnet disposed facing the first magnet face each other can be easily changed. This makes it possible to finely vary the operation feeling generated for the operator with a simple structure. In addition, since the area of the orthogonal projection plane is changed by moving in a relatively vertical direction, movement against the magnetic force does not occur, so that less force is required when changing the magnetic force. For this reason, it is possible to easily change the operation feeling.

  Further, in the operation feeling variable operation device according to the present invention, the magnetic force changing means includes a movable member on which the second magnet is disposed, a base member that supports the movable member so as to be movable in the vertical direction, An operation knob operable by an operator, wherein the base member has a flat base and a columnar columnar portion disposed on an upper surface of the base on the movable member side, and the columnar The portion is inserted into a through hole formed in the movable member and engaged with the operation knob, and an outer edge of the columnar portion guides the movement of the movable member in the vertical direction. It is said.

  According to this, even if the movable member provided with the second magnet is moved in order to make the magnetic force generated between the first magnet and the second magnet different, the position of the operation member does not change. Can be left. Accordingly, when the operator operates the operation member after changing the magnetic force, the position operated by the operator is not changed, so that the operation can be performed without a sense of incongruity, and the operability is not deteriorated.

  Further, in the operation feeling variable operation device according to the present invention, the columnar portion is rotatably arranged with respect to the base, and the magnetic force changing means is provided on an engagement member provided on a side surface of the columnar portion, A cam member provided on the movable member, wherein the engagement member and the cam member are disposed so as to be in contact with each other, the operation knob is operated, and the engagement member is rotated along with the rotation of the columnar portion.

  According to this, the movement of the movable member in the vertical direction can be easily and reliably performed, and the movement of the movable member in the vertical direction can be arbitrarily stopped. For this reason, the area of the orthogonal projection surface facing the first magnet and the second magnet can be changed steplessly. This makes it possible to make the operation feeling generated for the operator more finely while having a simple structure.

  In the operation feeling variable operation device according to the present invention, the magnetic force changing means includes an elastic member that biases the movable member, and the elastic member is disposed between the base and the movable member. It is characterized by that.

  According to this, the movement in the vertical direction of the movable member, and in turn, the second magnet disposed on the movable member can be suppressed, and rattling of the operation feeling variable operation device associated with vibration and operation can be prevented. . As a result, it is possible to suppress abnormal noise of the operation feeling variable operation device due to rattling.

  In the operation feeling variable operation device according to the present invention, the operation member is rotatable about a rotation axis, and the operation member has at least a part of a circumference of a circle around the rotation axis. The first magnet is disposed along the first magnet, and the second magnet is disposed facing the first magnet.

  According to this, with the configuration described above, it is possible to provide a rotary operation feel variable operation device with excellent operability.

  In the operation feeling variable operation device according to the present invention, a plurality of the first magnets are arranged symmetrically with respect to the rotation axis.

  According to this, a plurality of second magnets arranged opposite to the first magnet are also arranged point-symmetrically around the rotation axis. For this reason, the balance of the magnetic field formed between the first magnet and the second magnet is improved with respect to the rotation operation of the operation member. As a result, the operational feel is improved, and as a result, the operability is enhanced.

  The operation feeling variable operation device of the present invention can increase the magnetic force to increase the operation feeling and reduce the magnetic force to decrease the operation feeling.

FIG.

  First, the operation member 10 of the operation feeling variable operation device 100 uses a synthetic resin such as polybutylene terephthalate (PBT), as shown in FIGS. 3 and 5, and can be operated by an operator. It is comprised from the part 11, the operation shaft part 12 fitted with the operation part 11, and the holding | maintenance part 13 integrated with the operation shaft part 12. FIG. The operation member 10 is configured to be rotatable about the rotation axis KJ shown in FIG. 1 in response to the operation of the operator, and moves in the movement direction KD (rotation direction) shown in FIG. A pivoting action is performed. The moving direction KD at this time is the direction of the rotation operation along the XY plane shown in FIG.

  As shown in FIGS. 3 and 5, the operation portion 11 of the operation member 10 has a columnar shape that is easy for an operator to hold, and one end portion of the operation shaft portion 12 is inserted and screwed. As a result, the operation shaft portion 12 is fitted.

  Further, as shown in FIGS. 3 and 5, the holding portion 13 of the operation member 10 is formed integrally with the operation shaft portion 12, and includes a substrate body 13b having a cylindrical hole portion 13c, and a substrate body 13b. And a pair of side walls 13a each extending perpendicularly (in the direction along the Z direction shown in FIG. 5). The rotation axis KJ mentioned above passes through the center of the hole 13c.

  Next, as shown in FIG. 3, the support member 20 of the operation feeling variable operation device 100 includes two ring-shaped bearings 21 and a plate-like support body 22 having arm portions 22a extending in three directions. It is comprised. Then, as shown in FIG. 4, the two bearings 21 are housed in the hole 13 c of the holding portion 13 and are assembled so that one side is closed by the support body 22. Although not shown, the support 22 is fixed to the cover member 60 by screwing. In this manner, the holding portion 13 of the operation member 10 is disposed between the cover member 60 and the support body 22, so that the support member 20 supports the operation member 10 with the support body 22 and is supported by the bearing 21. The operation member 10 can be rotated. Note that, as shown in FIG. 6, a columnar portion 52d of a magnetic force changing means 50 described later is inserted into a hole provided in the center of the bearing 21 and the support 22 shown in FIG.

  Next, the first magnet 30 of the operation feeling variable operation device 100 is fixed to the iron yoke 31 shown in FIG. 3 using a plurality of permanent magnets, and as shown in FIG. 5 and FIG. The holding portion 13 is disposed inside each of the pair of side walls 13a. The plurality of permanent magnets of the first magnet 30 are arranged such that different magnetic poles are alternately adjacent to each other at a predetermined interval.

  Further, as shown in FIG. 8, the first magnet 30 is disposed along a part of the circumference of a circle with the rotation axis KJ as the center, and accompanying the turning operation of the operation member 10 by the operator. Then, the rotation operation is performed along the movement direction KD along the circumference of the circle around the rotation axis KJ. Although the operation is not shown, the first magnet 30 is moved while maintaining a constant distance from the second magnet 40 facing the first magnet 30.

  Further, as shown in FIG. 8, a plurality of (two in the first embodiment of the present invention) the first magnets 30 are arranged symmetrically about the rotation axis KJ. Accordingly, a plurality of second magnets 40 arranged to face the first magnet 30 are also arranged point-symmetrically about the rotation axis KJ. For this reason, a well-balanced magnetic field can be formed between the first magnet 30 and the second magnet 40 with respect to the rotation operation of the operation member 10.

  Similar to the first magnet 30, the second magnet 40 of the variable operation feeling operation device 100 uses a plurality of permanent magnets, is fixed to the iron yoke 41 shown in FIG. 3, and is attached to the magnet holder 42.

Are arranged so as to face each other.

  Further, like the first magnet 30, the plurality of permanent magnets of the second magnet 40 are arranged so that different magnetic poles are alternately adjacent at a predetermined interval. Thereby, in accordance with the movement of the first magnet 30 accompanying the movement of the operation member 10, the magnetic force is attracted or repelled continuously between the first magnet 30 and the second magnet 40. For this reason, an operation feeling can be generated by the first magnet 30 and the second magnet 40, and a good click feeling can be given to the operator at a predetermined interval. In particular, in the first embodiment of the present invention, both the first magnet 30 and the second magnet 40 are arranged such that a plurality of permanent magnets having different magnetic poles are alternately adjacent at a predetermined interval. Since magnetic force is generated mutually, attraction or repulsion of stronger magnetic force occurs. For this reason, a stronger click feeling can be given to the operator.

  Further, as described above, a plurality of second magnets 40 (two in the first embodiment of the present invention) are arranged symmetrically about the rotation axis KJ (see FIG. 8). That is, the first magnet 30 and the second magnet 40 are arranged opposite to each other on a concentric circle. In addition, since the rotation operation of the operation member 10 is performed along the circumference of a concentric circle with the rotation axis KJ as the center, the operation is excellent because the operation is unified to the rotation operation with the rotation axis KJ as the center. The rotary operation feeling variable operation device 100 can be provided. In addition, since both the first magnet 30 and the second magnet 40 are provided (two in the first embodiment), a stronger magnetic force can be attracted or repelled. A stronger click feeling can be given. In the first embodiment of the present invention, a plurality of permanent magnets are used side by side on the first magnet 30 and the second magnet 40. However, the present invention is not limited to this. For example, a single permanent magnet is used. The magnetic poles may be magnetized adjacent to each other at a predetermined interval.

Further, the second window hole 62a has an opening larger than the outer shape of the operation shaft portion 12 of the operation member 10, and enables the operation member 10 to move along the moving direction KD.

  Next, the operation of the operation feeling variable operation device 100 according to the first embodiment of the present invention will be described. FIG. 13 is a view for explaining the operation of the variable operation feeling operation device 100 according to the first embodiment of the present invention, and FIG. 13 (a) is a side view operated from the state of FIG. 10 (b). FIG. 13 (b) is a side view showing a further operation from the state of FIG. 13 (a). FIG. 14 is a view for explaining the operation of the operation feeling variable operation device 100 according to the first embodiment of the present invention. FIG. 14 (a) shows the first magnet 30 in the state of FIG. 10 (b). FIG. 14B is a side view schematically showing the second magnet 40, and FIG. 14B is a side view schematically showing the first magnet 30 and the second magnet 40 in the state of FIG. FIG. 14C is a side view schematically showing the first magnet 30 and the second magnet 40 in the state of FIG. FIG. 14 is a view of the first magnet 30 and the second magnet 40 viewed from the X1 side shown in FIG. 10B and FIG.

  First, in the first embodiment of the present invention, in the initial state, the variable operation feeling operation device 100 is configured such that the engaging member 55 contacts the base body 54a of the cam member 54 as shown in FIGS. It is arrange | positioned so that it may not contact with the cam part 54c of the cam member 54. FIG. In that case, the orthogonal projection surface T3 (T3a) where the first magnet 30 and the second magnet 40 face each other has an area as shown in FIG. The magnitude of this area determines the strength of the magnetic force generated between the first magnet 30 and the second magnet 40.

  Next, when the operation knob 56 shown in FIG. 2A is rotated in the clockwise direction, the columnar portion 52d of the base member 52 rotates in the clockwise direction, and is engaged with the rotation of the columnar portion 52d. The member 55 rotates in the clockwise direction. Then, the engaging member 55 and the cam portion 54c of the cam member 54 come into contact with each other, and the engaging member 55 is moved from the state shown in FIG. 10B to the state shown in FIG. 13A. It moves along the surface 54d. At this time, the engaging member 55 pushes the cam member 54, and the movable member 51 pushed through the cam member 54 moves downward (Z2 direction shown in FIG. 13) along the vertical direction VD. It becomes.

  And the 2nd magnet 40 arrange | positioned by the movable member 51 will also move below along the perpendicular direction VD. In this way, the first magnet 30 and the second magnet 40 are relatively moved in the vertical direction VD. In the state of FIG. 13A, the orthogonal projection surface T3 (T3b) where the first magnet 30 and the second magnet 40 face each other has an area as shown in FIG. The orthographic projection surface T3b shown in FIG. 14 (b) has a smaller area than the orthographic projection surface T3a shown in FIG. 14 (a). Thereby, the magnetic force generated between the first magnet 30 and the second magnet 40 can be changed to a smaller one.

  Further, when the operation knob 56 is rotated in the clockwise direction, the engaging member 55 moves along the cam surface 54d of the cam portion 54c from the state shown in FIG. 13A to the state shown in FIG. 13B. Finally, the cam portion 54c reaches the concave top portion 54e. In the state of FIG. 13B, the orthogonal projection surface T3 (T3c) where the first magnet 30 and the second magnet 40 face each other has an area as shown in FIG. The orthographic projection plane T3c shown in FIG. 14C has a smaller area than the orthographic projection plane T3b shown in b).

  Thus, in the operation feeling variable operation device 100 according to the first embodiment of the present invention, the area of the orthogonal projection surface T3 where the first magnet 30 and the second magnet 40 face each other is changed, and is proportional to the area. Since the magnetic force is gradually changed, the magnetic force can be easily and finely changed. For example, the magnetic force is adjusted more finely than when the magnetic force is changed by changing the distance between the first magnet 30 and the second magnet 40 (when the magnetic force is changed in inverse proportion to the square of the distance). Yes.

  Further, in the first embodiment of the present invention, the magnetic force changing means 50 moves the first magnet 30 and the second magnet 40 relatively along the vertical direction VD. It is possible to easily change the area of the orthogonal projection surface T3 where the first magnet 30 and the second magnet 40 disposed on the movable member 51 face each other. This makes it possible to finely vary the operation feeling generated for the operator with a simple structure. Further, since the area of the orthogonal projection plane T3 is changed by moving the first magnet 30 and the second magnet 40 relatively vertically, the direction is substantially perpendicular to the vector of the magnetic force generated mutually. Therefore, since the force required for adjusting the magnetic force is small, the magnetic force can be easily changed.

  Furthermore, in the first embodiment of the present invention, the second magnet 40 is mounted on the movable member 51 as a means for moving the first magnet 30 and the second magnet 40 in the vertical direction VD relatively. It is movable in the vertical direction VD. For this reason, even if the movable member 51 provided with the second magnet 40 is moved in order to make the magnetic force generated between the first magnet 30 and the second magnet 40 different, the position of the operation member 10 Can remain unchanged. As a result, when the operator operates the operation member 10 after changing the magnetic force, there is no change in the position operated by the operator, so that the operation can be performed without a sense of incongruity, and the operability is not lowered.

  On the other hand, when the operator rotates the operation knob 56 shown in FIG. 2 (a) in the counterclockwise direction, the variable operation feeling type operation device 100 changes from the state shown in FIG. 13 (b) to the state shown in FIG. 13 (a). After that, it is easily returned to the state of FIG. As described above, in the first embodiment of the present invention, the operation knob 56 is operated as a means for moving the movable member 51 in the vertical direction VD (the Z direction shown in FIG. 13), thereby engaging with the operation knob 56. A configuration is used in which the engaging member 55 moves along the cam surface 54d of the cam member 54 provided on the movable member 51 in accordance with the rotation of the combined columnar portion 52d. For this reason, the movement of the movable member 51 in the vertical direction VD can be performed smoothly and easily and reliably. This makes it possible to finely vary the operation feeling generated for the operator with a simple structure.

  The effects of the variable operation feeling operation device 100 according to the first embodiment of the present invention configured as described above will be described below.

  The operation feeling variable operation device 100 according to the first embodiment of the present invention includes a magnetic force changing unit 50 that varies the magnetic force generated between the first magnet 30 and the second magnet 40 that are arranged to face each other. Therefore, the operation feeling can be increased by increasing the magnetic force, and the operation feeling can be decreased by decreasing the magnetic force. For this reason, the operation feeling generated with respect to the operator can be varied according to the use situation. In addition, at least one of the first magnet 30 and the second magnet 40 is magnetized with different magnetic poles alternately adjacent to each other at a predetermined interval, so that the first magnet 30 moves as the operating member 10 moves. As a result, the magnetic force between the first magnet 30 and the second magnet 40 is attracted or repelled. For this reason, a good click feeling can be given to the operator at a predetermined interval. Accordingly, it is possible to provide the operation feeling variable operation device 100 that has a click feeling and can change the operation feeling.

  Further, since the magnetic force changing means 50 changes the area of the orthogonal projection surface T3 where the first magnet 30 and the second magnet 40 face each other, the magnetic force gradually increases in proportion to the area of the opposite orthogonal projection surface T3. Can be changed. This makes it possible to set a fine magnetic force. Further, for example, when the magnetic force generated between the first magnet 30 and the second magnet 40 is changed by changing the distance between the first magnet 30 and the second magnet 40 (change in inverse proportion to the square of the distance). As compared with the case (3), it is possible to easily create a change in the magnetic force, and it is possible to make the operation feeling generated for the operator finely different according to the use situation.

  In addition, since the magnetic force changing means 50 moves the first magnet 30 and the second magnet 40 relatively along the vertical direction VD, the first magnet 30 and the first magnet disposed on the operation member 10 side. The area of the orthogonal projection surface T3 facing the magnet 30 and the second magnet 40 disposed facing the magnet 30 can be easily changed. This makes it possible to finely vary the operation feeling generated for the operator with a simple structure. In addition, since the area of the orthogonal projection plane T3 is changed by moving in the vertical direction VD, movement against the magnetic force does not occur, so that less force is required when changing the magnetic force. . For this reason, it is possible to easily change the operation feeling.

  Further, since the base member 52 that guides the movement of the movable member 51 in the vertical direction VD is provided, the movable member 51 can be easily moved in the vertical direction VD. For this reason, even if the movable member 51 provided with the second magnet 40 is moved in order to make the magnetic force generated between the first magnet 30 and the second magnet 40 different, the position of the operation member 10 Can remain unchanged. As a result, when the operator operates the operation member 10 after changing the magnetic force, there is no change in the position operated by the operator, so that the operation can be performed without a sense of incongruity, and the operability is not lowered.

  Further, when the operation knob 56 is operated, the engaging member 55 is moved along the cam surface 54 d of the cam member 54 provided on the movable member 51 with the rotation of the columnar portion 52 d engaged with the operation knob 56. It is configured to move. For this reason, the movement of the movable member 51 in the vertical direction VD can be performed smoothly and easily and reliably. This makes it possible to finely vary the operation feeling generated for the operator with a simple structure.

  Further, since the magnetic force changing means 50 includes the elastic member 53 that urges the movable member 51, the movement of the movable member 51 and thus the second magnet 40 disposed on the movable member 51 is suppressed in the vertical direction VD. Can do. As a result, it is possible to prevent rattling of the operation feeling variable operation device 100 associated with vibration and operation, and to suppress abnormal noise of the operation feeling variable operation device 100 due to rattling.

  Further, the operating member 10 is rotatable about the rotation axis KJ, the first magnet 30 is disposed along a part of the circumference of the circle centered on the rotation axis KJ, and the second magnet 40 is the second magnet 40. A single magnet 30 is disposed so as to face each other. With such a configuration, it is possible to provide a rotary operation feel variable operation device 100 with excellent operability.

  In addition, since the plurality of first magnets 30 are arranged symmetrically with respect to the rotation axis KJ, the plurality of second magnets 40 arranged opposite to the first magnet 30 are also symmetrical with respect to the rotation axis KJ. Will be placed. For this reason, the balance of the magnetic field formed between the first magnet 30 and the second magnet 40 is improved with respect to the rotation operation of the operation member 10. As a result, the operational feel is improved, and as a result, the operability is enhanced.

  In addition, this invention is not limited to the said embodiment, For example, it can deform | transform and implement as follows, These embodiments also belong to the technical scope of this invention.

For example, as shown in FIG. 15C, the area of the orthogonal projection surface T3e may be changed by relatively rotating the first magnet 30c and the second magnet 40c. In FIG. 15C, the first magnet 30c is rotated, but either one or both of the first magnet 30c and the second magnet 40c may be rotated.

<Modification 6>
In the first embodiment, the magnetic force changing means 50 includes the cam member 54 and the engaging member 55, and the movable member 51 is moved along the vertical direction VD by the cam structure.

Although not shown, the magnetic force changing means of Modification 6 includes a new pressing member on the side surface of the columnar portion 52d so that the columnar portion 52d of the base member 52 is engaged with the base 52a by a screw structure. When the operation knob 56 is operated and the columnar portion 52d rotates, the pressing member presses the movable member 51 with the rotation of the columnar portion 52d. Accordingly, the movable member 51 can be easily and reliably moved in the vertical direction VD, and since the screw is cut, the movement of the movable member 51 in the vertical direction VD can be arbitrarily stopped. For this reason, the area of the orthogonal projection surface T3 where the first magnet 30 and the second magnet 40 face each other can be changed steplessly. This makes it possible to make the operation feeling generated for the operator more finely while having a simple structure.

<Modification 7>

Also good. Accordingly, the movement of the movable member 51 in the vertical direction VD can be stopped corresponding to the flat portion or the recessed portion, and the area of the orthogonal projection surface T3 where the first magnet 30 and the second magnet 40 face each other can be reduced. It can be changed in stages.

Can be changed.
