Description

The present invention relates to an operating device and an electronic device, and more particularly to an operating device that generates a click feeling when the user operates the device.

Generally, an electronic device such as a digital camera is provided with a rotation operation device for setting shooting conditions and selecting various functions by rotating a rotation operation member such as a dial. Then, some of these types of rotation operation devices are designed to generate a click feeling at the time of operation, and the user can intuitively grasp the operation amount by the generation of the click feeling.

Conventionally, a configuration using an elastic member and a cam has been used to impart (generate) this click feeling. However, in this configuration, repeated use may cause wear and weaken the click feeling.

To solve such a problem, for example, a click feeling is obtained by using the attractive force and the repulsive force of the ring-shaped multi-pole magnet and the fixed magnet that are rotated integrally with the rotation operation member and multi-pole magnetized in the circumferential direction. Some of them are given (Patent Document 1).

With reference to FIGS. 2 to 5, the sub-dial device 50 includes a dial operation unit (rotation operation member) 501 operated by the user. The dial operation unit 501 can rotate about the rotation shaft 50a. The dial operation unit 501 is formed with an uneven shape along the circumferential direction on its circumferential surface so that it can be easily rotated by a finger. A set button 51 is arranged in the center of the dial operation unit 50, and the changed set value can be determined by pressing down the set button 51. A dial holding member 502 is arranged on the back surface side of the dial operating portion 501, and the magnet holding member 503 is fastened to the dial holding member 502. As a result, the dial operation unit 501 is rotatably held by the dial holding member 502.

A shield member 508 and a multi-pole magnet 505 are arranged on the magnet holding member 503. When the dial operation unit 501 is rotated by the user, the multi-pole magnet 505 is integrally rotated.

As shown in FIG. 5A, the multi-pole magnet 505 is formed in a ring shape, and S poles and N poles are alternately arranged along the circumferential direction, and these plurality of magnetic poles are in the direction of the rotation axis 50a. It is magnetized in. In the illustrated example, the multi-pole magnet 505 has 20 poles at equal intervals, but the distance between the magnetic poles and the number of poles are not limited to the illustrated example.

The shield member 508 is a magnetic material and is arranged between the magnet holding member 503 and the multi-pole magnet 505. The shield member 508 can prevent the magnetic flux from the multi-pole magnet 505 from leaking to the dial operation unit 501 side. Further, the shield member 508 shields the magnetic field noise flowing from the outside from the magnetic field noise, and suppresses the influence of the magnetic field noise at the time of rotation detection described later.

A detection board 506 is arranged below the dial operation unit 501 and the set button 51, and the operation amount of the dial operation unit 501 is detected by the detection board 506.

As shown in FIG. 4B, the hole IC 506a is arranged on the detection substrate 506, and the hole IC 506 faces the multi-pole magnet 505. Then, the magnetic flux density of the multi-pole magnet 505 can be detected by the Hall IC 506a, and the rotation step amount according to the rotation direction and the number of poles of the dial operation unit 501 can be obtained according to the detection result.

The Hall IC 506a and the multi-pole magnet 505 are not in contact with each other, and a clearance (gap) is set within a range in which a magnetic field can be detected.

A set button detection unit 506b is provided on the detection board 506, and the set button detection unit 506b is formed of an elastic member and is in contact with the lower end of the set button 51. Then, when the set button 51 is pressed down, the set button detection unit 506b is deformed, and the pressing of the set button 51 is detected by the continuity of the pattern formed on the detection board 506.

The movable magnet (movable portion) 507 shown in FIG. 5B is a magnet for imparting a click feeling, and is rotatably held by the dial base portion 504. The movable magnet 507 has at least two poles of magnetic poles. In the illustrated example, the movable magnet 507 is defined by two magnets as a first magnetic pole surface (first magnetic pole portion) 507a and a second magnetic pole surface (second magnetic pole portion) 507b.

As shown in FIG. 4B, the movable magnet 507 is arranged in the vicinity of the multi-pole magnet 505 in a direction in which the magnetizing surfaces face each other, and the number of movable magnets 507 increases depending on the combination of magnetic poles of the movable magnet 507 and the multi-pole magnet 505. An attractive force (attractive force) or a repulsive force is generated between the polar magnet 505 and the movable magnet 507 (the attractive force and the repulsive force are acting forces).

FIG. 6 is a diagram showing a state before the dial operation unit is operated in the sub-dial device shown in FIG. Further, FIG. 7 is a diagram showing a state in which the dial operation unit is being operated in the sub-dial device shown in FIG. Further, FIG. 8 is a diagram showing a state in which the dial operation unit is operated in the sub-dial device shown in FIG. 3 to complete the rotation for one magnetic pole.

With reference to FIGS. 6 to 8, the generation of a click feeling when the user operates the dial operation unit 501 will be described. In addition, in FIGS. 6 to 8, the positional relationship between the multi-pole magnet 505, the movable magnet 507, and the hall IC 506a when the dial operation unit 501 is rotated is schematically shown. The hatched portion indicates the north pole, and the hollow (white background) portion indicates the south pole.

FIG. 6 shows a stable state in which the dial operation unit 501 is not operated, and the S pole of the multi-pole magnet 505 and the N pole which is the first magnetic pole surface 507a of the movable magnet 507 face each other and face each other. Adsorption power is working. At this time, there is a gap between the multi-pole magnet 505 and the movable magnet 507, and they are not in contact with each other. Further, the N pole of the multi-pole magnet 505 is located near the N pole which is the second magnetic pole surface 507b, and repulsive forces are generated from each other.

Therefore, the positional relationship between the multi-pole magnet 505 and the movable magnet 507 is stable in the state shown in FIG. 6, and the force for stopping the dial operation unit 501 acts by the attraction between the multi-pole magnet 505 and the first magnetic pole surface 507a. To do. In the illustrated example, in order to obtain a stable static force, the overlapping area of the first magnetic pole surface 507a and the multipolar magnet 505 is set to be 7 times or more the overlapping area of the second magnetic pole surface 507b and the multipolar magnet 505. Will be done. The second magnetic pole surface 507b and the multi-pole magnet 505 do not have to overlap.

When the user rotates the dial operation unit 501 in the clockwise (CW) direction from the state shown in FIG. 6, the state shifts to the state shown in FIG. By the rotation operation by the user, the suction between the S pole of the multi-pole magnet 505 and the N pole which is the first magnetic pole surface 507a of the movable magnet 507 is separated. Subsequently, as the multi-pole magnet 505 rotates in the CW direction, the north pole of the multi-pole magnet 505 approaches the north pole which is the first magnetic pole surface 507a, and a repulsive force begins to be generated.

On the other hand, since the S pole of the multi-pole magnet 505 approaches the N pole of the second magnetic pole surface 507b, an attractive force begins to be generated. The state shown in FIG. 7 is an unstable state, and the above-mentioned suction force and repulsive force generate a force in the direction of transition to the state shown in FIG.

In the process of transitioning from the state shown in FIG. 6 to the state shown in FIG. 8, the overlapping area of the second magnetic pole surface 507b and the multipolar magnet 505 is the overlapping area of the first magnetic pole surface 507a and the multipolar magnet 505. The magnitude of the superposed area is reversed from the state shown in FIG.

When the rotation operation is continued from the state shown in FIG. 7, the state shifts to the state shown in FIG. In this state, the south pole of the multi-pole magnet 505 and the north pole of the second magnetic pole surface 507b of the movable magnet 507 are opposed to each other, and an attractive force acts. Similar to the state shown in FIG. 6, the multi-pole magnet 505 and the movable magnet 507 are not in contact with each other. Further, the N pole of the multi-pole magnet 505 is located in the vicinity of the N pole which is the first magnetic pole surface 507a, and repulsive forces are generated from each other.

Therefore, in FIG. 8, which is one magnetic pole from the state shown in FIG. 6, that is, in the state of being rotated by 18 degrees, a force for stopping the rotation of the dial operation unit 501 acts. Then, as in the state shown in FIG. 6, the overlapping area of the second magnetic pole surface 507b and the multipolar magnet 505 is set to be 7 times or more the overlapping area of the first magnetic pole surface 507a and the multipolar magnet 505. Magnet. The first magnetic pole surface 507a and the multipole magnet 505 do not have to overlap.

During the transition to the state shown in FIGS. 6 to 8 by the rotation operation by the user, after the attraction between the first magnetic pole surface 507a and the multi-pole magnet 505 is separated, the dial operation unit 501 has one magnetic pole ( 18 degrees) A force that is attracted to the rotated phase works. As a result, when the user rotates the dial operation unit 501, a click feeling can be obtained for each magnetic pole step, and a more intuitive rotation operation becomes possible. When the dial operation unit 501 is operated in the counterclockwise direction (CCW), the states change in the order shown in FIGS. 8 to 6, and a click feeling can be obtained in the same manner.

By the way, as shown in FIG. 6, the width W of the first magnetic pole surface 507a and the second magnetic pole surface 507b of the movable magnet 507 is set to be substantially the same as the width of one magnetic pole of the multipolar magnet 505. As a result, it is possible to provide the user with a click feeling with less play when the dial operation unit 501 is operated. When the width W is shorter than the width of one magnetic pole of the multi-pole magnet 505, the margin (time) from the start of operating the dial operation unit 501 to the acquisition of a click feeling becomes large.

Further, from the state shown in FIGS. 6 to 8, the multi-pole magnet 505 and the movable magnet 507 give a click feeling by an attractive force and a repulsive force without contacting each other in a direction substantially parallel to the magnetizing plane. By imparting a click feeling in a non-contact manner in this way, it is possible to construct a highly durable dial operation device that is less likely to be worn even if repeated operations are performed.

As shown in FIGS. 6 to 8, during the dial operation, one of the magnetic pole surfaces of the multi-pole magnet 505 and the movable magnet 507 is always superimposed, and an attractive force or a repulsive force is generated and a force acts on each other. .. As a result, the dial operation feeling is not lost during the operation, and the click feeling can be stably given.

FIG. 9 is a diagram showing a cross section taken along the line BB shown in FIG.

Here, the arrangement of the rotation shaft of the movable magnet 507 will be described with reference to FIG. As described with reference to FIGS. 6 to 8, the movable magnet 507 rotates in a range from a state in which the movable magnet 507 is substantially superimposed on the ring-shaped multipolar magnet 505 to the inside of the ring shape. The rotation shaft of the movable magnet 507 is provided with a minute fitting backlash for rotation. Therefore, when the state transitions from FIG. 6 to FIG. 7, as shown in FIG. 9, the movable magnet 507 is tilted due to the repulsive force between the multipolar magnet 505 and the movable magnet 507.

By arranging the rotating shaft inside the ring shape, the movable magnet 507 is tilted so that the inside of the ring shape is lowered, and the repulsive force causes the movable magnet 507 to move in a desired direction (dashed line arrow). work.

In the illustrated example, the state in which the movable magnet 507 repeats rotation toward the inside of the ring shape is shown, but a form in which the movable magnet 507 rotates outward is also possible, and in that case, the rotation shaft is also the same. It is desirable to place it on the outside of the ring shape.

In the first embodiment of the present invention, a click feeling is given by the multi-pole magnet 505 and the movable magnet 507 magnetized in the thrust direction with respect to the rotating shaft 50a. However, regarding the magnetizing direction, for example. , May be magnetized in the radial direction. Further, although the rotation axis 50a of the multipolar magnet 505 and the rotation axis of the movable magnet 507 are in the same direction, the direction is not limited to the same direction, and for example, the rotation axis may be rotated by 90 degrees.

As described above, in the first embodiment of the present invention, in an operating device such as a sub-dial device, it is possible to improve the small size and durability while giving a click feeling at the time of rotation operation.

[Second Embodiment]
Next, an example of the operating device according to the second embodiment of the present invention will be described.

FIG. 10 is a perspective view showing an example of an operating device according to a second embodiment of the present invention. 11A and 11B are views showing the slider operating device shown in FIG. 10 in an exploded manner, FIG. 11A is a diagram showing a multi-pole magnet, and FIG. 11B is a diagram showing a movable magnet.

In the first embodiment described above, a dial operating device using a dial as the operating device has been described. On the other hand, in the second embodiment, an operation device that uses a slide operation instead of the rotation operation (hereinafter, referred to as a slide operation device in the second embodiment) will be described.

The slide operation device is used, for example, in an imaging device such as a digital camera, and is used when making various settings in the same manner as the dial operation device described above. Further, also in the second embodiment, the slide operation amount is detected by the Hall IC.

The slider operating device has a slider holding member 901, and the slider 902 is held by the slider holding member 901 so as to be movable (sliding movable) in the direction of the solid arrow. The slider 902 is formed with a slide operation shape portion 902a used when the user slides the slider 902. A multi-pole magnet 903 is fixed to the slider 902 so as to slide integrally. The slide operation shape portion 902a is formed with irregularities so that the fingers do not slip easily when the user operates the slide operation shape portion 902a.

As shown in FIG. 11A, the multi-pole magnet 903 is magnetized so that the S pole and the N pole are alternately arranged along the moving direction of the slider 902. In the illustrated example, the multipole magnet 903 has 10 magnetic poles, but the distance between the magnetic poles and the number of magnetic poles are not limited to this example.

A movable magnet 904 is rotatably held in the slider holding member 901 around a rotating shaft 901b. The slider holding member 901 is provided with a stopper-shaped portion (regulating member) 901a that regulates the rotation range of the movable magnet 904. The movable magnet 904 has a first magnetic pole surface 904a and a second magnetic pole surface 904b.

The movable magnet 904 is a magnet for imparting a click feeling by an attractive force and a repulsive force with respect to the multipolar magnet 903. The movable magnet 507 described in the first embodiment has two N poles, but in the illustrated example, the movable magnet 904 has an S pole and an N pole.

As shown in FIG. 10, the movable magnet 904 is arranged in the vicinity of the multi-pole magnet 903 with its magnetizing surfaces facing each other, and the multi-pole magnet 903 and the movable magnet 904 are arranged according to the combination of magnetic poles. Generates adsorption and repulsion.

FIG. 12 is a diagram showing a state in which the slider is not operated in the slide operation device shown in FIG. FIG. 13 is a diagram showing a state in which the slider is operated from the state shown in FIG. Further, FIG. 14 is a diagram showing a state in which the slider is further operated from the state shown in FIG.

In FIG. 12, the S pole of the multi-pole magnet 903 and the N pole, which is the first magnetic pole surface 904a of the movable magnet 904, face each other, and attractive forces act on each other. Further, the S pole of the multi-pole magnet 903 is located in the vicinity of the S pole which is the second magnetic pole surface 904b, and repulsive forces are generated from each other. Therefore, the positional relationship between the multi-pole magnet 903 and the movable magnet 904 is stable in the state shown in FIG. 12, and the force that keeps the slider 902 in the state shown in FIG. 12 by attracting the multi-pole magnet 903 and the first magnetic pole surface 904a. Occurs.

When the slider 902 is slid to the left in the figure from the state shown in FIG. 12, the state shown in FIG. 13 shifts. By the user's operation, the suction between the south pole of the multi-pole magnet 903 and the north pole of the first magnetic pole surface 904a of the movable magnet 904 is separated. Subsequently, the N pole of the multi-pole magnet 903 approaches the N pole of the first magnetic pole surface 904a, and the movable magnet 904 rotates in the direction indicated by the broken line arrow due to the repulsive force.

At this time, even if the magnet rotates in the direction opposite to the direction indicated by the broken line arrow, the movable magnet 904 abuts on the stopper-shaped portion 901a, so that the rotation in the direction opposite to the direction indicated by the broken line arrow is restricted.

In this way, the stopper-shaped portion 901a regulates the movement of the movable magnet 904 in the wrong direction, and can surely give a click feeling.

The state shown in FIG. 13 is an unstable state, and the repulsive force and the suction force described above exert a force to shift to the state shown in FIG.

When the sliding operation is further continued, the state shown in FIG. 13 shifts to the state shown in FIG. Here, the north pole of the multi-pole magnet 903 and the south pole of the second magnetic pole surface 904b of the movable magnet 904 are close to each other to generate an attractive force. Further, the N pole, which is the first magnetic pole surface 904a, is close to the N pole of the multi-pole magnet 903, and repulsive forces are generated from each other. Due to these suction force and repulsive force, a force for stopping the vehicle at a position moved by the width S2 from the state shown in FIG. 12 acts.

After the reaction force that separates the multi-pole magnet 903 and the first magnetic pole surface 904a acts by sequentially shifting to the states shown in FIGS. 12 to 14 by the user's slide operation, the multi-pole magnet 903 and the second The attractive force due to the magnetic pole surface 904b acts.

As a result, when the user touches and operates the slide operation shape portion 902a, a click feeling can be obtained at preset intervals, and the slide operation can be performed more intuitively. When the slide operation shape portion 902a is operated in the opposite direction, a transition can be obtained in the states shown in FIGS. 14 to 12 to obtain a click feeling.

In the second embodiment described above, the width S2 and the width S1 of the magnetic poles are not the same, and the interval at which the click feeling occurs can be changed, and as described in the first embodiment, one magnetic pole can be used. Not limited.

In the second embodiment, the horizontal slide operation has been described, but for example, the operation member may be latitudeed along the curved rail.

As described above, in the second embodiment of the present invention, in an operation device such as a slide operation device, it is possible to improve the small size and durability while giving a click feeling at the time of the slide operation.

It is sectional drawing along the line.

In FIG. 16A, the S pole of the multi-pole magnet 505 and the first magnetic pole surface 607a (N pole) of the movable magnet 607 face each other. In addition, in FIG. 16A, the magnetic pole (N pole) of the first magnetic pole surface 607a is shown in a state where the surface facing the multi-pole magnet 505 is transmitted. In this state, the magnetic field lines (not shown) of the inclined portion 607a1 and the flat surface portion 607a3 of the first magnetic pole surface 607a are directed to the S pole of the multipole magnet 505.

In FIG. 16C, the inclined portion 607a1 of the first magnetic pole surface 607a and the north pole of the multi-pole magnet 505 face each other. In this state, magnetic field lines are generated from the inclined portion 607a1 in the normal direction of the surface (arrow N). Therefore, a repulsive force is generated between the first magnetic pole surface 607a and the N pole of the multi-pole magnet 505, and the movable magnet 607 receives a force in the direction opposite to the arrow N.

When the moving direction of the movable magnet 607 is indicated by an arrow R, as shown in FIG. 16E, the angle AN formed by the arrow N and the arrow R is an obtuse angle. Therefore, the force received by the movable magnet 607 includes a component in the arrow R direction, and a force that rotates the movable magnet 607 in the arrow R direction acts.

As described in the first embodiment, when the first magnetic pole surface 507a is completely parallel to the multipolar magnet 505, the direction is opposite to the desired direction at the timing when the movable magnet 507 starts to move due to the repulsive force of the magnetic poles. It may rotate in the direction of. In this case, the second magnetized surface 507b cannot be attracted, and a desired click feeling cannot be generated.

Therefore, if a stopper or the like is provided to regulate the rotation direction of the movable magnet 507 only in a desired direction, the stopper and the movable magnet 507 collide with each other, so that sound is generated and durability is lowered.

Therefore, in the third embodiment, the inclined portion 607a1 whose normal direction of the surface forms an obtuse angle with the moving direction of the movable magnet 607 is formed on the first magnetic pole surface 607a of the movable magnet 607. As a result, when the movable magnet 607 is rotated by the repulsive force, the movable magnet 607 can be reliably rotated in a desired direction. As a result, it is possible to prevent the generation of sound and the deterioration of durability and obtain a good click feeling.

In FIG. 16 (f), the movable magnet 607 starts rotating, and a repulsive force continues to act between the first magnetic pole surface 607a and the north pole of the multi-pole magnet 505. On the other hand, an attractive force acts between the second magnetic pole surface 607b and the S pole of the multi-pole magnet 505. When the multi-pole magnet 505 rotates in the CW direction, the second magnetic pole surface 607b of the movable magnet 607 is attracted to the S pole of the multi-pole magnet 505 as in the first embodiment. Then, the movable magnet 607 rotates to a position where the first magnetic pole surface 607a does not face the multipolar magnet 505 and becomes a stable state. In this process, a click feeling can be obtained in the same manner as in the first embodiment.

The width w1 and the width w2 of the inclined portions 607a1 and 607a2 of the first magnetic pole surface 607a are equal as described above, and the inclinations are also the same. Therefore, for example, even when the multi-pole magnet 505 rotates in the direction opposite to that of FIG. 16B (CCW direction) from the state of FIG. 16A, the movable magnet 607 is specified in the same manner as in the above-described operation. It can be reliably rotated in the direction to obtain a good click feeling.

Further, since the first magnetic pole surface 607a and the second magnetic pole surface 607b have the same shape, when the multipolar magnet 505 is rotated from a state where the second magnetic pole surface 607b side faces the multipolar magnet 505. But you can get a click feeling as well.

As shown in FIG. 15B, the width w3 of the flat surface portion 607a3 is larger than the width w1 of the inclined portion 607a1 and the width w2 of the inclined portion 607a2. Here, the above effect can be obtained even if the width w3 is set to zero and the entire surface of the first magnetic pole surface 607a is set as a slope. However, since the magnetic force is reduced in the component in the direction orthogonal to the magnetic pole surface of the multipolar magnet 505 due to the slope, there is a concern that the click feeling is weakened.

Therefore, as described above, the inclined portions 607a1 and 607a2 are formed at both ends of the first magnetic pole surface 607a with a predetermined width, and the remaining portion is a flat surface portion 607a3 parallel to the multipolar magnet 505. As a result, it is possible to prevent the movable magnet 607 from reversing and obtain a good click feeling while minimizing the decrease in the click feeling. The shape of the movable magnet 607 is not limited to forming an inclined portion.

FIG. 17 is a diagram for explaining another example of the movable magnet used in the dial operating device according to the third embodiment of the present invention. 17 (a) is a view seen from above, and FIG. 17 (b) is a cross-sectional view taken along the line FF shown in FIG. 17 (a).

In FIG. 17A, a first magnetizing surface 707a and a second magnetizing surface 707b are formed at both ends of the movable magnet 707, respectively. Then, the stepped portion 707a1 and the stepped portion 707a2 and the stepped portion 707b1 and the stepped portion 707b2 may be provided on the magnetized surface. In this case, both the first magnetizing surface 707a and the second magnetizing surface 707b are N poles.

As shown in FIG. 17B, due to the presence of the step portion 707b1, the magnetic field in the vicinity of the second magnetized surface 707b has a component in the arrow P direction orthogonal to the direction of the step. As a result, when the step portion 707b1 faces the north pole of the multipole magnet (not shown), it receives a force in the opposite direction of the arrow P, that is, in the direction of the arrow R in which the movable magnet 707 rotates. ..

In this way, the above-mentioned effect can be obtained even if a step is provided instead of the slope.

As described above, also in the third embodiment of the present invention, in the dial operation device, it is possible to improve the small size and durability while giving a click feeling at the time of the rotation operation.

[Fourth Embodiment]
Next, an example of the operating device according to the fourth embodiment of the present invention will be described.

FIG. 18 is a diagram for explaining the movement of the movable magnet in the operating device according to the fourth embodiment of the present invention. FIG. 18A is a diagram showing the relationship between the multipolar magnet and the movable magnet from above, and FIG. 18B is a diagram showing the relationship between the multipolar magnet and the movable magnet from the side. 18 (c) is a view showing the movable magnet from above, and FIG. 18 (d) is a view showing the movable magnet from the side.

In the illustrated example, a click feeling is generated by using a multi-pole magnet 805 having 12 magnetic poles and a movable magnet 807 that reciprocates along a predetermined axis. The movable magnet 807 can move only in the direction of the arrow T and in the direction opposite to the arrow T in the drawing.

A first magnetized surface 807a (N pole) is formed on one end of the movable magnet 807 on a surface facing the multi-pole magnet 805, and a second magnetized surface 807b (S pole) is formed on the other end. There is. In the state shown in FIG. 18A, the S pole of the multipole magnet 805 and the first magnetized surface 807a (N pole) are attracted to each other and are in a stable state. When the multi-pole magnet 805 rotates in the CW direction from this state, the north pole of the multi-pole magnet 805 and the first magnetizing surface 807a repel each other, and the movable magnet 807 moves in the direction of the arrow T. At the same time, the second magnetizing surface 807b and the north pole of the multi-pole magnet 805 start to attract, so that the movable magnet 807 is attracted in the direction of arrow T.

When the multi-pole magnet 805 is rotated by one magnetic pole in this way, a click feeling is generated by the repulsive force and the attractive force as in the above-mentioned example.

As shown in FIG. 18C, slope portions 807a1 and 807a2 and slope portions 807b1 and 807b2 are formed on the first magnetized surface 807a and the second magnetized surface 807b, respectively. The slope portions 807a1 and 807a2 face the same direction, and the angle formed by the arrow N in the normal direction and the arrow T in the moving direction of the movable magnet 807 is tilted so as to be an obtuse angle.

Therefore, when the multi-pole magnet 805 rotates from the state shown in FIG. 18A, the repulsive force acting on the movable magnet 807 has a component in the arrow T direction, so that the movable magnet 807 can be reliably moved in the desired direction. It can be moved to (arrow T).

Further, the slope portions 807b1 and 807b2 are slopes having a normal line having an obtuse angle with respect to the vector in the direction opposite to the arrow T. As a result, even when the multi-pole magnet 805 rotates from the state where the second magnetizing surface 807b faces the multi-pole magnet 805, the movable magnet 807 is moved in a desired direction (direction opposite to the arrow T). Can be done.

The slope portions 807a1, 807a2, 807b1 and 807b2 have the same shape except for the direction of inclination. A flat surface portion 807a3 is formed between the slope portions 807a1 and 807a2, and a flat surface portion 807b3 is formed between the slope portions 807b1 and 807b2. Therefore, the same click feeling can be generated regardless of the position of the movable magnet 807 in the rotation direction of the multi-pole magnet 805. Furthermore, the movable magnet 807 can be reliably moved in a desired direction while preventing a decrease in the click feeling.

In this way, even if the movable magnet 807 is reciprocated to generate a click feeling, if the magnetized surface of the movable magnet 807 is tilted in an obtuse angle with respect to the moving direction vector of the movable magnet 807, it is certain. Can generate a click feeling.

As described above, also in the fourth embodiment of the present invention, it is possible to improve the small size and durability while imparting a click feeling.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various modifications and modifications can be made within the scope of the gist thereof.
