  An X-direction electromagnet 14x (also shown in FIG. 6), which is a substantially cylindrical electromagnet, is attached to the electromagnet holder 12a in the apparatus case 12, and the shaft 13 serves as a hollow portion of the X-direction electromagnet 14x. It is inserted. The electromagnet in the second moderation device 10 is provided as a Y-direction electromagnet 14y (see FIG. 6).

A cylindrical sleeve-shaped rotation resistance receiving portion 15 is provided on the right side of the X direction electromagnet 14x in the shaft 13 so as to rotate integrally with the shaft 13, and the inner surface of the rotation resistance receiving portion 15 is provided. As shown in FIG. 2, a substantially V-shaped concave surface portion 16 is formed. The concave portion 16 is substantially V-shaped with the slope 16a and the slope 16b.
Further, a resistance applying means 17 is provided on the shaft 13 portion inside the rotation resistance receiving portion 15. The resistance applying unit 17 includes a member to be attracted 18, a coil spring 19 made of steel wire, a pressing member 20, and a guide tube 21.

  The attracted member 18 is made of a magnetic material, and has a cylindrical portion 18a and a large attracted portion 18b formed at the lower end of the cylindrical portion 18a. The attracted portion 18b is opposed to the X-direction electromagnet 14x in the axial direction. The attracted member 18 is rotatably fitted to the shaft 13.

  The guide cylinder 21 is attached to the cylindrical portion 18a of the attracted member 18 so as to extend in the centrifugal direction, and the pressing member 20 is movably accommodated and disposed in the distal end side of the guide cylinder 21. Yes. Further, the coil spring 19 is accommodated in a compressed state inside the guide tube 21. The coil spring 19 is composed of a steel wire, for example, a spring steel wire. As shown in FIG. 2, the pressing member 20 is pressed and urged by the spring force of the coil spring 19 toward the center of the valley of the concave surface portion 16.

  The X-direction position sensor 9a is a rotation position detecting means, and is composed of, for example, a potentiometer. The X-direction position sensor 9a detects a rotation position (angular position) of the joystick member 6 in the X direction, and this 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 rotational position detecting means, and is composed of, for example, a potentiometer, and detects the rotational position (angular position) of the joystick member 6 in the Y direction. The position detection signal is given to the control device 11. The Y-direction position sensor 10 a is included in the second moderation device 10.

  The control device 11 shown in FIG. 6 includes a microcomputer and the like, and controls the control means in the first moderation device 9, the control means in the second moderation device 10, and the control of the vehicle screen operation system. It also serves as a means, and further has a function of instructing 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 14x of the first moderation device 9 and the second moderation device 10. The Y-direction electromagnet 14y is energized and deenergized 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 in order to help understanding. 1 and 2, the X-direction electromagnet 14x is disconnected (the Y-direction electromagnet 14y is also disconnected). In this state, the pressing member 20 is pressed and urged to the central part of the valley of the concave surface portion 16 of the rotational resistance receiving portion 15, so that the attracted member 18 can rotate with respect to the shaft 13. If the user tilts the joystick member 6 in the XL direction of FIG. 3 from this state, the first swing member 7 swings in the XL direction, and the shaft 13, the rotation resistance receiving portion 15, X The 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 16 of the rotation resistance receiving portion 15, and the attracted member 18 is rotatable with respect to the shaft 13. The pressing member 20 also rotates integrally (see FIG. 8A). That is, when the X-direction electromagnet 14x is disconnected, both the rotation resistance receiving portion 15 and the resistance applying means 17 are rotated in accordance with the tilting operation of the joystick member 6, and no feeling of moderation occurs (FIG. 7). , Angle range a1 ° in FIG.

  When the angle range a1 ° is exceeded, the X-direction electromagnet 14x is energized, and the electromagnet 14 attracts and fixes the attracted portion 18b facing the attracted member 18 by this energization. As a result, the pressing member 20 is fixed in a non-rotatable state. In contrast, the rotation resistance receiving portion 15 is continuously rotated in the direction of arrow A in response to the rotation operation force by the user. At this time, as shown in FIG. 8B, the inclined surface 16b of the concave surface portion 16 of the rotational resistance receiving portion 15 is in sliding contact with the pressing member 20, and the spring force of the coil spring 19 in the pressing direction increases. The rotation resistance receiving portion 15 makes the user feel the rotation resistance strongly. As a result, a feeling of resistance, that is, moderation acts on the user (angle range a2 ° in FIG. 7). When the X-direction electromagnet 14x is disconnected when the angle range a2 ° is exceeded, the suction fixation or suction fixation is released, the moderation feeling is released, and a click feeling is applied.

  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 position detection signal of the shaft 13 of the first moderation device 9 by the position sensor 9a of the first moderation device 9 and the second moderation device 10. Is detected based on the rotation position detection signal of the shaft 13 of the second moderation device 10 by the Y-direction position sensor 10a.

  In this case, the tilt range that is the operable range in the X direction of the joystick member 6 is αx ° (see FIG. 3), and the tilt range that is the operable range in the Y direction is αy °. Assume that the icons m1, m2, m3, m4, m5, and m6 of FIG. 9 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 (instructible area) Ma of the screen M of the display device 2 as shown in FIG.

  In this state, when the joystick member 6 is operated in the YL direction, for example, as shown in FIG. 11, the Y-direction electromagnet of the second moderation device 10 in the operation region y1 corresponding to the icon m2 and the icon m5. 14y 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 in the XL direction, for example, the virtual point moves from the power disconnection region x1 to the energization region x2, so the X direction electromagnet 14x 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.

  For example, when the icon m1 is instructed to be selected by the joystick member 6, when the determination switch (not shown) is turned on, the screen is switched to FIG. In this case, the number of icons increases, but the X-direction electromagnet 14x and the Y-direction electromagnet 14y are energized and disconnected as shown in FIG. For example, when the joystick member 6 indicates the icon mn, if the joystick member 6 is tilted in the X direction, the X-direction electromagnet 14x is turned off as shown in FIG. When the tilting operation is performed in the YL direction or the XR direction, the Y-direction electromagnet 14y 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 joystick device 3 of this embodiment, the first moderation device 9 that imparts moderation in the X direction (first operation direction) of the joystick member 6 and the moderation in the Y direction (second operation direction). Since each of the second moderation devices 10 that imparts a moderation imparts moderation using the electromagnets 14x and 14y, it is possible to contribute to a reduction in cost and good moderation response. Furthermore, since the moderation can be given by energization and power interruption of the electromagnets 14x and 14y, the timing for giving the moderation can be appropriately set by setting the timing of this power interruption. Further, the setting of the inclination angle between the coil spring 19 and the concave surface portion 16 makes it easy to set the moderation feeling and the interval.

  Moreover, according to the vehicle operation system 1 of the present embodiment, in addition to the same effects as described above, moderation is provided at a timing that matches the number, arrangement, and size of the icons displayed on the display device 2. This improves the operability associated with the display screen.

  In the above-described embodiment, the rotation resistance receiving portion 15 of the rotation resistance receiving portion 15 and the resistance applying means 17 is provided so as to be integrally rotatable with the shaft 13 that is the rotation member. The resistance applying means 17 is configured to rotate integrally with the shaft 13 when the electromagnets 14x and 14y are disconnected, and is attracted to the electromagnets 14x and 14y and fixed in a non-rotating state when the electromagnets 14x and 14y are energized. However, as shown in FIGS. 13 and 14 shown as the second embodiment of the present invention, the resistance applying means 17 is provided so as to be integrally rotatable with a sleeve 13a formed on the shaft 13, and the rotational resistance receiving member is provided. The portion 15 is provided on the member to be attracted 18 having a circular flat plate shape, and rotates integrally with the shaft 13 when the electromagnets 14x and 14y are disconnected, and is attracted to the electromagnets 14x and 14y when the electromagnets 14x and 14y are energized. Non-rotating It may be configured to be constant. In short, one of the rotation resistance receiving portion and the resistance applying means is provided so as to be integrally rotatable with the rotation member, and the other is integrally rotated with the rotation member when the electromagnet is disconnected. What is necessary is just to set it as the structure which is attracted | sucked to this electromagnet at the time of electricity supply, and is fixed to a non-rotating state.

  In the third embodiment having such a configuration, for example, when the joystick member 6 is operated in the direction of the arrow XL in FIG. 15, the electromagnet 14x is energized in the energization region R2 portion, and operation resistance is given. That is, the joystick member 6 does not hit one end (operation limit portion) or the other end (operation limit portion) of the slit 8a, and can prevent a sense of incongruity such as a hit during operation and occurrence of a hit sound. It is. Further, when the joystick member 6 is operated in the direction of the arrow YL in FIG. 15, the electromagnet 14y is energized in the energization region R4, and an operation resistance is given, so that the joystick member 6 is provided with the slit 8a. It does not hit one end portion (operation limit portion) or the other end portion (operation limit portion), and can prevent a sense of incongruity such as a hit at the time of operation and occurrence of a hit sound.

As described above, according to the third embodiment, the joystick member 6 does not hit the operation limit portion at the time of the operation related to the display screen M, and the uncomfortable feeling of the operation can be eliminated.

However, as shown in FIGS. 17 and 18 showing the fourth embodiment of the present invention, the entire display screen M is the active area. It may be. In this case, the inner peripheral area corresponds to the portion R from the outermost end of the display screen M. In the third and fourth embodiments, the operation limit portion of the joystick member 6 is exemplified by both end portions of the slits 7a and 8a of the swing members 7 and 8. However, for the swing restriction provided separately. A stopper may be used.
