Description

  The present invention relates to a moderation device that gives moderation to operation of an operation member.

  Conventionally, a rotary switch device used for various controls of an automobile, for example, a moderation surface portion having alternating ridges and valleys formed on the inner surface of the case, like the switch device disclosed in Patent Document 1, It has a moderation mechanism comprising a coil spring provided on the rotor side in the case and a ball urged so as to abut on the moderation surface portion by the coil spring.

According to the moderation mechanism having such a configuration, when the user performs the switch operation by rotating the operation knob, the ball moves over the peak portion to the valley portion with the rotation of the rotor. Depressed. That is, the feedback force applied to the operation knob changes before and after the ball exceeds the mountain. Thereby, moderation is given to rotation of the operation knob (operation member).
Japanese Utility Model Publication No. 5-94922

  In the above-mentioned Patent Document 1, the rotation angle at which the moderation is given when the operation member is rotated (hereinafter referred to as the moderation angle) is limited by the formation pitch (angle pitch) of the peak and valley portions of the moderation surface. There is a problem. As a solution to this problem, a moderation device having the configuration shown in FIG. 20 is considered.

  In FIG. 20, for example, a shaft 103 a is rotatably supported on the apparatus main body 102 attached to an appropriate part on the back side of the instrument panel 101. An operation portion 103b is attached to an end portion (upper end portion in the drawing) of the shaft 103a that protrudes to the surface side of the instrument panel 101 so as to rotate integrally with the shaft 103a. In this case, the operation member 103 is comprised by the operation part 103b and the axis | shaft 103a. Further, a disk 105a of the rotary encoder 105 for detecting the rotational position of the operation member 103 is attached to the lower end of the shaft 103a so as to rotate integrally with the shaft 103a.

  Further, the attracted portion 106 is provided on the lower end side of the shaft 103a so as to rotate integrally with the shaft 103a, and the attracted body 106a made of a magnetic plate is attached to the upper surface of the attracted portion 106. . An electromagnet 107 is provided above the attracted body 106a so that the electromagnet 107 can rotate independently of the shaft 103a and can move up and down at a minute distance. Spring plates 108 and 108 made of synthetic resin are provided between the electromagnet 107 and the apparatus main body 102. One end of each of the spring plates 108 and 108 is attached to the apparatus main body 102, and the other end is the It is attached to an electromagnet 107. The spring plates 108 and 108 provide resistance against the rotation of the shaft 103a. An appropriate operation object is attached to or connected to the shaft 103a.

  In the configuration shown in this figure, the electromagnet 107 is normally disconnected, and when the operation member 103 is rotated by the user, the shaft 103a, the disk 105a, and the attracted portion 106 rotate together. When the operation member 103 is rotated by a predetermined angle, the rotary encoder 105 detects this predetermined angle, and based on this, a control unit (not shown) energizes the electromagnet 107. Then, the electromagnet 107 and the object to be adsorbed 106a are in an adsorbed state, and the electromagnet 107, the object to be adsorbed 106a, and the operation member 103 are in an integrated state. Accordingly, when the user further rotates the operation member 103 from this state, the other end of the spring plates 108 and 108 is elastically deformed in the rotation direction, thereby generating a spring force in the restoring direction, and the user rotates. When resistance is received and the electromagnet 107 is turned off, there is no rotational resistance. Moderation is given by the difference in rotational resistance.

  However, in this configuration, since the spring plates 108 and 108 made of synthetic resin are used, it is difficult to set a shape for achieving a spring function, and it is also difficult to select a material for setting the spring force. There was a problem that was difficult. In addition, it is difficult to set subtle settings such as a smoothness degree of moderation or a sudden degree.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a moderation device in which the moderation angle can be easily set and the moderation feeling can be easily set.

  In order to achieve the above-described object, the moderation device according to claim 1 includes an operation member provided in the device main body so as to be rotatable, and a substantially V-shaped concave surface provided so as to rotate integrally with the operation member. A rotation resistance receiving portion having a portion, a coil spring and a pressing member made of steel wire, and pressing the pressing member against the concave portion of the rotation resistance receiving portion by the spring force of the coil spring. A rotation applying mechanism having a resistance applying means for applying a rotation resistance, a drive member that rotates integrally with the resistance applying means, a driven member that is rotated based on the rotation of the drive member, and the apparatus main body. An electromagnet that allows rotation of the driven member when power is cut off and attracts the driven member to fix the driven member in a non-rotating state when energized, and a position that detects a rotation position of the operation member Detection means and the position detection means And a control means for controlling disconnection of the electromagnet according to the rotation position of the operation member, and when the electromagnet is disconnected, the rotation resistance receiving portion and the resistance applying means are accompanied by the rotation of the operation member. The drive member and the driven member of the rotation transmission mechanism rotate, and the driven member is attracted to the electromagnet and fixed in a non-rotating state when the electromagnet is energized. The drive member and the resistance applying means are fixed to the non-rotating state.

  In the above configuration, when the electromagnet is disconnected, when the user rotates the operation member, the rotation resistance receiving unit rotates together with the operation member, and the resistance applying unit rotates together with the operation member. Therefore, when the electromagnet is turned off, both the turning resistance receiving portion and the resistance applying means are turned in accordance with the turning operation of the operation member, and a feeling of moderation does not occur. At this time, the drive member of the rotation transmission mechanism rotates integrally with the resistance applying means, and the driven member is also rotated based on the rotation of the drive member. When the operating member reaches a predetermined rotation position, the predetermined rotation position is detected by the position detection means, and the electromagnet is energized by the control means. By this energization, the driven member of the rotation transmission mechanism is attracted to the electromagnet and fixed in the non-rotation state. Then, the driving member and the resistance applying means are also fixed in a non-rotating state, and the pressing member of the resistance applying means slides relatively on the concave surface portion of the rotating resistance receiving portion against the spring force of the coil spring. Thus, the spring force of the coil spring is increased and the resistance is increased. When the operation member reaches a predetermined rotation position, the electromagnet is cut off, and the rotation of the driven member is allowed. Accordingly, the rotation of the resistance applying means and the drive member is also allowed. And the resistance is lost. A feeling of moderation occurs due to a sudden change in resistance caused by the coil spring.

  In the case of this configuration, the moderation angle can be easily changed by changing the predetermined rotation position. Moreover, it has a rotation resistance receiving part which has a substantially V-shaped concave surface part, and a steel wire coil spring and a pressing member, and the said pressing member is made into the said concave surface part of a rotation resistance receiving part with the spring force of this coil spring. With the resistance applying means for pressing against the rotation force to give the rotation resistance, the moderation is given, so the selection of the coiled spring and the setting of the inclination angle of the concave part can set the interval and strength of the moderation feeling. It becomes easy. Further, in this case, when the resistance applying means is fixed in the non-rotating state, the electromagnet can be attracted and fixed only by the driven member of the rotation transmitting mechanism, so that the electromagnet can be reduced in size.

  In order to achieve the same object, the moderation device according to claim 2 is an operation member provided on the device main body so as to be capable of turning operation, a turning resistance receiving portion having a substantially V-shaped concave portion, and a steel wire. The coil spring and the pressing member are provided so as to rotate integrally with the operation member. The spring force of the coil spring presses the pressing member against the concave portion of the rotation resistance receiving portion. A rotation applying mechanism having a resistance applying means for applying a rotation resistance, a drive member that rotates integrally with the rotation resistance receiving portion, and a driven member that is rotated based on the rotation of the drive member; An electromagnet provided in the apparatus main body, which allows the driven member to rotate when power is cut off and attracts the driven member to fix the driven member in a non-rotating state when energized, and detects the rotational position of the operating member. Position detecting means to detect and detected by this position detecting means Control means for controlling the disconnection of the electromagnet according to the rotation position of the operation member, and when the electromagnet is disconnected, the resistance applying means and the rotation resistance receiving portion are associated with the rotation of the operation member. Based on the fact that the drive member and the driven member of the rotation transmission mechanism are rotated together with the rotation transmission mechanism, and the driven member is attracted to the electromagnet and fixed in the non-rotation state when the electromagnet is energized. The drive member and the rotation resistance receiving portion are configured to be fixed in a non-rotation state.

  The moderation device according to claim 2 is configured such that, in the moderation device according to claim 1 described above, the positions of the rotation resistance receiving portion and the resistance applying means are switched, and the resistance applying means is always rotated integrally with the operation member. This is different from claim 1. In the moderation device of claim 2 configured as described above, the same effect as that of the moderation device of claim 1 can be basically obtained only by changing the positions of the rotational resistance receiving portion and the resistance applying means. Can do.

  According to the first and second aspects of the present invention, the moderation angle can be easily set, and various settings such as the moderation feeling can be easily performed. In addition, it is possible to reduce the size of the electromagnet.

  Now, the first moderation device 9 and the second moderation device 10 have the same configuration, and the first moderation device 9 will now be described. As shown in FIG. 1, the first moderation device 9 includes a device case 12 as a device body. The operation case 13 constituting the operation member is rotatably supported on the device case 12. One end portion of the first swing member 7 is attached to the end portion of the operation shaft 13 protruding from the one end portion of the apparatus case 12 so as to rotate integrally. In the operation shaft 13, a cylindrical sleeve-shaped rotation resistance receiving portion 14 is provided at an end inside the apparatus case 12 so as to rotate integrally with the operation shaft 13. A substantially V-shaped concave surface portion 15 is formed on the inner surface of the rotational resistance receiving portion 14 as shown in FIG. The concave portion 15 is substantially V-shaped with the slope 15a and the slope 15b.

  A first shaft 16 is rotatably provided at a substantially central portion in the device case 12. The first shaft 16 is disposed on the same axis as the operation shaft 13, and a base end portion (left end portion in FIG. 1) is rotatably supported on the bottom portion 12 a of the apparatus case 12. A resistance applying means 17 is provided on the outer peripheral portion of the first shaft 16 on the distal end side. The resistance applying means 17 includes a guide tube 18, a coil spring 19 made of steel wire, and a pressing member 20.

  The guide cylinder 18 is disposed so as to protrude radially outward from the outer peripheral portion of the first shaft 16, and is attached to the first shaft 16 so as to rotate integrally therewith. A bullet-shaped pressing member 20 is accommodated and disposed at the tip of the guide cylinder 18 so as to be movable in the axial direction of the guide cylinder 18. In the guide tube 18, the coil spring 19 is accommodated and disposed in a compressed state so as to be positioned between the pressing member 20 and the first shaft 16. Due to the spring force of the coil spring 19, the pressing member 20 is pressed and urged toward the center of the valley of the concave surface portion 15 as shown in FIG. 2.

  In the first shaft 16, a drive gear (gear) 21 constituting a drive member is attached to an outer peripheral portion of an intermediate portion in the axial direction so as to rotate integrally with the first shaft 16. Therefore, the first shaft 16, the resistance applying means 17, and the drive gear 21 are configured to rotate integrally around the first shaft 16.

  An X-direction electromagnet 22x (also shown in FIG. 7), which is a substantially cylindrical electromagnet, is disposed in the device case 12 between the first shaft 16 and the side wall 12b of the device case 12. Has been. The X-direction electromagnet 22x is fixed to an electromagnet holder 23 provided in a fixed state on the side wall 12b of the device case 12. In addition, the electromagnet in the 2nd moderation apparatus 10 is provided as the electromagnet 22y for Y directions (refer FIG. 7).

  The electromagnet holder 23 is provided with a shaft support portion 24, and a second shaft 25 is rotatably supported by the shaft support portion 24. The second shaft 25 is disposed in parallel with the first shaft 16 in a state of passing through the hollow portion 26 of the X-direction electromagnet 22x. A driven gear (gear) 27 constituting a driven member is attached to a distal end portion of the second shaft 25 protruding from the hollow portion 26 so as to rotate integrally with the first shaft 16. The driven gear 27 is made of a magnetic material and is disposed so as to be close to the X-direction electromagnet 22x. When the driven gear 27 is made of a nonmagnetic material, a magnetic member to be attracted is provided on the surface of the driven gear 27 on the X-direction electromagnet 22x side. As shown in FIG. 3, the teeth 27a of the driven gear 27 are engaged with the teeth 21a of the drive gear 21, and the driven gear 27 is also rotated when the drive gear 21 is rotated. Become. The drive gear 21 and the driven gear 27 constitute a rotation transmission mechanism 29.

  The X-direction position sensor 9a is a position detection means, and is composed of, for example, a potentiometer. The X-direction position sensor 9a detects the rotational position (angular position) of the joystick member 6 in the X direction, and thus the rotational position of the operation shaft 13. The rotation position detection signal is given to the control device 11. The X-direction position sensor 9 a is also included in the first moderation device 9.

  The Y-direction position sensor 10a is also a position detecting means, and is composed of, for example, a potentiometer. The Y-direction rotation position (angular position) of the joystick member 6 and the rotation position of the operation shaft 13 are also included. This rotation position detection signal is given to the control device 11. This Y-direction position sensor 10 a is included in the second moderation device 10.

  The control device 11 shown in FIG. 7 includes a microcomputer and the like. The control means in the first moderation device 9, the control means in the second moderation device 10, and the vehicle screen operation system 1 It also serves as a control means, and further has a function of instructing to select one of a plurality of icons displayed on the display device 2. The control device 11 receives the rotation position detection signal from the X-direction position sensor 9a and the Y-direction position sensor 10a and receives the X-direction electromagnet 22x of the first moderation device 9 and the second moderation device 10. The Y-direction electromagnet 22y is energized and de-energized at a predetermined rotational position. In addition, although this power interruption pattern is mentioned later, it is changed with the display screen of the said display apparatus 2. FIG.

  The operation of the first moderation device 9 will be described. 1 and 2, the X-direction electromagnet 22x is disconnected (the Y-direction electromagnet 22y is also disconnected). In this state, the pressing member 20 is pressed and urged to the center of the valley of the concave surface portion 15 of the rotation resistance receiving portion 14. Further, the teeth 21 a of the drive gear 21 of the rotation transmission mechanism 29 and the teeth 27 a of the driven gear 27 are engaged with each other. Since the X-direction electromagnet 22x is disconnected, the driven gear 27 is not attracted to the X-direction electromagnet 22x, and the driven gear 27 is allowed to rotate.

  If the user tilts the joystick member 6 in the XL direction in FIG. 4 from this state, the first swing member 7 swings in the XL direction, and the operation shaft 13, the rotation resistance receiving portion 14, The X-direction position sensor 9a rotates integrally in the direction of arrow A in FIG.

  In this case, as described above, the pressing member 20 is pressed and urged to the center of the valley of the concave surface portion 15 of the rotation resistance receiving portion 14, and the driven gear 27 is rotatable with respect to the X-direction electromagnet 22x. Accordingly, the pressing member 20 also rotates integrally with the rotation resistance receiving portion 14 (see FIG. 9A). That is, when the X-direction electromagnet 22x is disconnected, both the rotational resistance receiving portion 14 and the resistance applying means 17 are rotated in accordance with the tilting operation of the joystick member 6, and no sense of moderation is generated (FIG. 8). , Angle range a1 ° in FIG. At this time, the drive gear 21 rotates integrally with the first shaft 16, and the driven gear 27 meshed with the drive gear 21 is also rotated.

  When the angle range a1 ° is exceeded, the X-direction electromagnet 22x is energized, and the X-direction electromagnet 22 attracts or fixes the driven gear 27 by this energization. As a result, the driven gear 27 is fixed in a non-rotatable state, and accordingly, the drive gear 21, the first shaft 16, and the resistance applying means 17 are also fixed in a non-rotatable state. On the other hand, the rotation resistance receiving portion 14 continues to rotate in the direction of arrow A in response to a rotation operation force by the user. At this time, as shown in FIG. 9B, the inclined surface 15a of the concave surface portion 15 of the rotational resistance receiving portion 14 comes into sliding contact with the pressing member 20, and the spring force of the coil spring 19 in the pressing direction increases. The user feels the rotation resistance strongly through the rotation resistance receiving portion 14. As a result, the user feels resistance, that is, moderation (angle range a2 ° in FIG. 8).

  When the X-direction electromagnet 22x is disconnected when the angle range a2 ° is exceeded, the X-direction electromagnet 22x is no longer attracted or attracted to the driven gear 27, and the driven gear 27 is rotated. The moderation feeling is released and the click feeling acts. When the X-direction electromagnet 22x is disconnected in this way, the pressing member 20 of the resistance applying means 17 returns to the center of the valley of the concave surface portion 15 of the rotation resistance receiving portion 14 again, and the rotation resistance receiving portion 14 and It comes to rotate integrally.

Note that the operation of the second moderation device 10 is basically the same as that of the first moderation device 9, and a detailed description thereof will be omitted.
Here, an operation of the vehicle screen operation system 1 configured by the joystick device 3 and the display device 2 having such a configuration (operation of the control means of the vehicle screen operation system 1) will be described. Now, it is assumed that the joystick member 6 is at the center position in the X direction and the Y direction. The rotation position of the joystick member 6 in the X direction and the Y direction is determined by the rotation position detection signal of the operation shaft 13 of the first moderation device 9 and the second position by the X direction position sensor 9a of the first moderation device 9. This is detected based on the rotational position detection signal of the operation shaft 13 of the second moderation device 10 by the Y-direction position sensor 10a of the moderation device 10 of the moderation device.

  In this case, the tilt range in the X direction of the joystick member 6 is αx ° (see FIG. 4), and the tilt range in the Y direction is αy °. Assume that the icons m1, m2, m3, m4, m5, and m6 of FIG. 10 are now displayed on the display screen M of the display device 2. The icon m1 means a 50 sound search for destination setting or facility search.

  In this state, a virtual screen (according to the detection result of the X-direction position sensor 9a detecting the X-direction center and the Y-direction position sensor 10a detecting the Y-direction center) by the joystick member 6 at the center position. The instruction point P is substantially at the center of the active area (instructable area) Ma of the screen M of the display device 2 as shown in FIG.

  When the joystick member 6 is operated in the YF direction in this state, for example, as shown in FIG. 12, in the operation region y1 corresponding to the area between the icon m2 and the icon m5, the Y-direction electromagnet of the second moderation device 10 22y is energized, a feeling of moderation is given at this time, and a click feeling acts when the power is cut off.

  For example, when the operation angle of the joystick member 6 reaches the icon m2 region, it is detected that the Y-direction position sensor 10a has reached the icon m2, and the icon m2 is displayed in a discriminatory manner (such as making it brighter). It is instructed to select m2. In addition, the X direction area | region of this icon m2 is made into the power disconnection area | region. In this icon m2, when the joystick member 6 is operated, for example, in the XR direction, the virtual point moves from the disconnection region x1 to the energization region x2, so the X direction electromagnet 22x is energized and moves to the next icon m3. The power is cut off at the place.

  As described above, the areas between the icons are energized areas, and the icon area and the outermost icon outer area are deenergized areas. In other words, moderation is given when an icon is operated.

  In addition, for example, when the selection switch (not shown) is turned on when the icon m1 is instructed to be selected by the joystick member 6, the screen is switched to FIG. In this case, although the number of icons increases, the X-direction electromagnet 22x and the Y-direction electromagnet 22y are energized and disconnected as shown in FIG. For example, when the joystick member 6 is pointing to the icon mn, if the joystick member 6 is tilted in the X direction, the X-direction electromagnet 22x is turned off as shown in FIG. When the tilting operation is performed in the Y direction, the Y-direction electromagnet 22y is disconnected as shown in FIG. Also in this case, between the icons is an energized area, and the icon area and the outermost icon outer area are an uninterrupted area, and a moderation is given when the icons are operated.

According to the above embodiment, the following effects can be obtained.
Since the first moderation device 9 and the second moderation device 10 are configured to apply moderation by energization and disconnection of the X-direction electromagnet 22x and the Y-direction electromagnet 22y, respectively, the X-direction electromagnets 22x and Y The moderation angle can be easily changed by changing the timing at which the direction electromagnet 22y is energized and de-energized (the rotation position of the operation shaft 13). Further, by setting the spring force of the coil spring 19 of the resistance applying means 17 and setting the inclination angle of the concave surface portion 15 of the rotation resistance receiving portion 14, the moderation feeling can be easily set and the interval can be easily set.

  Further, in this case, a rotation transmission mechanism 29 including a drive gear 21 and a driven gear 27 is provided between the resistance applying means 17 and the electromagnet (X-direction electromagnet 22x, Y-direction electromagnet 22y), and resistance is applied. When the means 17 is fixed in the non-rotating state, the electromagnet is adsorbed and fixed only by the driven gear 27 of the rotation transmitting mechanism 29. For this reason, since the driven gear 27 can be set small, it is possible to reduce the size of the electromagnets (the X-direction electromagnet 22x and the Y-direction electromagnet 22y). Further, since the drive gear 21 and the driven gear 27 are engaged with each other, the current position can be maintained even when the electromagnets (the X-direction electromagnet 22x and the Y-direction electromagnet 22y) are disconnected.

  Here, for example, in the first moderation device 9, the operating shaft 13 rotates in one direction (refer to the direction of arrow A in FIG. 2), and the X-direction electromagnet 22 x switches from the disconnected state to the energized state. The rotation direction of the operation shaft 13 is reversed in the middle of the rotation (rotation in the direction opposite to the arrow A), and the rotation position of the operation shaft 13 is a position at which the X-direction electromagnet 22x is switched to the disconnected state. May pass. In such a case, in this embodiment, as shown in FIG. 3, there is a gap 30 between the teeth 22a of the drive gear 21 and the teeth 27a of the driven gear 27. When reversed (in FIG. 3, the rotation direction of the drive gear 21 changes from the direction of the arrow A to the direction opposite to the arrow A), the teeth 22a of the drive gear 21 and the teeth 27a of the driven gear 27 correspond to the gap 30. A state where the gears do not mesh with each other temporarily occurs, and a state where the driven gear 27 does not rotate temporarily even when the drive gear 21 rotates is generated. Since the resistance corresponding to the gap 30 is not generated, the pressing member 20 of the resistance applying unit 17 does not start climbing the slope of the concave surface portion 15 of the rotational resistance receiving portion 14. For this reason, even when the rotation direction of the operating shaft 13 is reversed, the position where the X-direction electromagnet 22x is disconnected before the pressing member 20 starts to climb the slope of the concave portion 15 can be detected. It can be prevented from occurring.

  According to the joystick device 3 of the above-described embodiment, the first moderation device 9 for imparting moderation in the X direction of the joystick member 6 and the second moderation device 10 for imparting moderation in the Y direction are both electromagnets (X direction). Therefore, it is possible to contribute to a reduction in cost as compared with the case of using a motor, and the moderation responsiveness is also good. Further, according to the vehicle operation system 1 in the present embodiment, moderation can be given at a timing that matches the number, arrangement, and size of the icons displayed on the display device 2, and the operability related to the display screen is improved. To do.

(Second embodiment)
Next, a second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and different parts will be described. The second embodiment is different from the first embodiment in the configuration of the rotation transmission mechanism in the moderation device (the first moderation device 9 and the second moderation device 10).

  Since the first moderation device 9 and the second moderation device 10 have the same structure, the first moderation device 9 will be described as a representative. The rotation transmission mechanism 35 includes an elongated link 36 that constitutes a drive member, and a circular rotation plate 37 that constitutes a driven member. Among these, the link 36 has one end connected to the first shaft 16 so as to rotate integrally with the first shaft 16, and has an engaging convex portion 38 at the other end. The rotation plate 37 is connected to the second shaft 25 so as to rotate integrally with the second shaft 25 and has a guide groove 39 extending in the radial direction. The engaging projection 38 is slidably inserted into the guide groove 39. The rotating plate 37 is made of a magnetic material and is disposed so as to be close to the X-direction electromagnet 22x. When the rotating plate 37 is made of a nonmagnetic material, a magnetic member to be attracted is provided on the surface of the rotating plate 37 on the X-direction electromagnet 22x side.

  In the above-described configuration, the X-direction electromagnet 22x is now disconnected, and the pressing member 20 of the resistance applying unit 17 is pressed and urged to the central portion of the concave portion 15 of the rotational resistance receiving portion 14 (see FIG. 2). Assume that the engaging convex portion 38 of the link 36 in the rotation transmission mechanism 35 is inserted in the innermost part of the guide groove 39 in the rotation plate 37 as shown in FIG. In the state where the X-direction electromagnet 22x is in a disconnected state, the rotation plate 37 is allowed to rotate. In this state, when the operation shaft 13 (rotation resistance receiving portion 14) is rotated in the direction of arrow A in FIG. 2, the resistance applying means 17 is also rotated in the direction of arrow A together with the first shaft 16. The Further, the link 36 together with the first shaft 16 also rotates in the direction of arrow A in FIG. Then, as shown in FIGS. 16A to 16C, the engaging plate 38 slides on the guide groove 39 of the rotating plate 37, and the rotating plate 37 has an arrow about the second shaft 25. It is rotated in the B1 direction. When the operation shaft 13 (the turning resistance receiving portion 14) is turned in the direction opposite to the arrow A in FIG. 2, the resistance applying means 17, the link 36, and the turning plate 37 are the same as described above. It is turned in the opposite direction. In this case, since the engaging convex part 38 needs to be inserted in the guide groove 39, it is necessary to limit the rotation range of the link 36 to β (see FIG. 16C).

  On the other hand, for example, when the X-direction electromagnet 22x is energized when the link 36 is rotated in the direction of arrow A and reaches the position shown in FIG. The directional electromagnet 22x is fixed by suction or suction. Thereby, the rotation plate 37 is fixed in a non-rotatable state, and accordingly, the link 36, the first shaft 16, and the resistance applying means 17 are also fixed in a non-rotatable state. On the other hand, the rotation resistance receiving portion 14 continues to rotate in the direction of arrow A in response to a rotation operation force by the user. At this time, the slope 15a of the concave surface portion 15 of the rotation resistance receiving portion 14 comes into sliding contact with the pressing member 20, and the spring force of the coil spring 19 in the pressing direction increases, and the user moves the rotation resistance receiving portion 14 to the rotation resistance receiving portion 14. Thus, the rotation resistance is felt strongly (see FIG. 9B). When the X-direction electromagnet 22x is deenergized, the X-direction electromagnet 22x is not attracted or attracted to the rotation plate 37, and the rotation plate 37 is allowed to rotate. The pressing member 20 returns to the center of the valley of the concave surface portion 15 of the rotation resistance receiving portion 14 again and rotates integrally with the rotation resistance receiving portion 14. As a result, the moderation feeling is canceled and a click feeling is applied.

  Also in the second embodiment having such a configuration, it is possible to obtain basically the same effects as those of the first embodiment described above. In the second embodiment, the rotation transmission mechanism 35 is a rotation plate having a link 36 having an engagement projection 38 and a guide groove 39 in which the engagement projection 38 is slidably moved. 37, the electromagnet (X-direction electromagnet 22x, Y-direction electromagnet 22y) is adsorbed and fixed when the resistance applying means 17 is fixed in the non-rotating state. Only 37 is sufficient. For this reason, it is possible to reduce the size of the electromagnets (X-direction electromagnet 22x, Y-direction electromagnet 22y) by setting the rotation plate 37 small. Further, since the engaging convex portion 38 of the link 36 is inserted into and engaged with the guide groove 39 of the rotating plate 37, even if the electromagnet (the X-direction electromagnet 22x, the Y-direction electromagnet 22y) is disconnected, The position can be maintained.

  Further, in the second embodiment, the rotation transmission mechanism 35 is constituted by the link 36 having the engagement convex portion 38 and the rotation plate 37 having the guide groove 39, as shown in FIG. Even if the first shaft 16 that is the rotation center of the link 36 and the second shaft 25 that is the rotation center of the rotation plate 37 are slightly displaced in the lateral direction (see the displacement dimension C), If the engaging convex portion 38 is inserted and engaged with the guide groove 39, the movement of the link 36 can be transmitted to the rotating plate 37, and if the rotating plate 37 is fixed so as not to rotate, the link 36 can be fixed. Can also be fixed non-rotatable. For this reason, a slight axial deviation due to assembly can be allowed.

In the above-described second embodiment, the engaging convex portion 38 may be provided on the rotating plate 37 side, and the guide groove 39 may be provided on the link 36 side.
(Third embodiment)
18 and 19 show a third embodiment of the present invention, which differs from the first embodiment described above in the following points. That is, in the third embodiment, the positions of the rotational resistance receiving portion and the resistance applying means are interchanged. Specifically, the configuration is as follows.

A rotation resistance receiving portion 41 having a substantially V-shaped concave surface portion 40 is integrally provided at the distal end portion of the first shaft 16. The concave portion 40 is substantially V-shaped by the slope 40a and the slope 40b. In this case, as long as the rotation resistance receiving portion 41 is configured to rotate integrally with the first shaft 16, the rotation resistance receiving portion 41 may be configured by a separate member. The resistance applying means 17 is provided on the inner surface of the cylindrical portion 42 provided integrally with the operating shaft 13 so as to rotate integrally with the cylindrical portion 42. Similarly to the first embodiment, the resistance applying means 17 includes a guide cylinder 18, a coil spring 19, and a bullet-shaped pressing member 20, so that the guide cylinder 18 rotates integrally with the cylindrical portion 42. The pressing member 20 is pressed and biased to the concave portion 15 by being fixed. In addition, the outer peripheral part at the front end side of the guide cylinder 18 is formed in a tapered shape so as to be tapered.
Even in the case of such a configuration, basically the same operational effects as those of the first embodiment can be obtained.

(Other embodiments)
The present invention is not limited to the above-described embodiments, and can be modified or expanded as follows.
The rotation position detection means for detecting the rotation position of the operation shaft 13 is not limited to a potentiometer, and may be a rotary encoder or a combination of a plurality of Hall ICs and magnetic poles. Further, the pressing member may be spherical instead of the bullet shape.
