    • A multi-directional input apparatus includes an operating member including a shaft portion which extends to the outside, a housing having an opening through which the shaft portion extends and configured to support the operating member in a tiltable manner, interlocking members moved by the operating member when the shaft portion is tilted, and detectors which detect changes in the positions of the interlocking members. A sliding member is externally fitted to the shaft portion such that the sliding member is movable in an axial direction, and a coil spring is disposed between a flange provided on the shaft portion and the sliding member. A rubbing surface of the sliding member is in elastic contact with a receiving surface on an inner wall of an annular edge portion surrounding the opening. The rubbing surface and the receiving surface are spherical surfaces centered on a tilting center of the shaft portion.
    • 多向输入装置包括操作构件,该操作构件包括延伸到外部的轴部,具有开口的壳体,所述轴部通过该开口延伸并构造成以可倾斜的方式支撑操作构件,由操作构件移动的互锁构件 当轴部倾斜时,检测器检测互锁构件的位置的变化。 滑动构件外部装配到轴部,使得滑动构件可沿轴向移动,并且螺旋弹簧设置在设置在轴部分上的凸缘和滑动构件之间。 滑动构件的摩擦表面与围绕开口的环形边缘部分的内壁上的接收表面弹性接触。 摩擦面和接收面是以轴部的倾斜中心为中心的球面。

    • A force-feedback multidirectional input device includes a slider slidably supported by a support base and an operation knob joined to the slider. In a sliding operation, the slider operates in conjunction with actuating members included in a force-feedback unit. Therefore, a sense of force based on the sliding is fed back to the operation knob. Furthermore, the slider is elastically urged by coil springs toward an inner bottom surface of a housing space defined in the support base. In a depressing operation, the operation knob presses the support base downward against the urging force of coil springs. Therefore, a vertically movable member joined to the support base is moved downward along guide portions (convex rails and concave grooves). Thus, a push switch provided on a pedestal (circuit board) is pressed and activated by the vertically movable member.
    • 力反馈多向输入装置包括由支撑基座可滑动地支撑的滑块和连接到滑块的操作旋钮。 在滑动操作中,滑块与包括在力 - 反馈单元中的致动构件一起操作。 因此,基于滑动的力的感觉被反馈到操作旋钮。 此外,滑块被螺旋弹簧弹性地推向限定在支撑基座中的壳体空间的内底表面。 在按压操作中,操作旋钮克服螺旋弹簧的推力向下按压支撑底座。 因此,与支撑基座接合的可升降构件沿着引导部(凸轨和凹槽)向下移动。 因此,设置在基座(电路板)上的按钮开关被可垂直移动的构件按压并启动。
