  • Patent number: 8322239
    Abstract: A controller capable of realizing continuous click feelings within an operation range of the controller and a specific click feeling at a specific position of the operation range with continuous natural maneuvering feeling. When a first member to which an element shaft of an electronic device is fixed is rotated relatively to a second member to which an element body of the electronic device is fixed to rotate the shaft, the controller adjusts the control amount the element. A notch array, formed of a serration and a first pawl, and a position confirmation means, formed of a notch and a pawl, are disposed between the first member and the second member. Both members are disposed oppositely with respect to the shaft. A center click feeling, different from the feeling in the notch array, can be obtained at the center within the range of the notch array.

  • Patent number: 7256679
    Abstract: A stick lever unit is provided that is capable of eliminating uncomfortable feeling during manipulation of the stick, as well as, minimizing breaking of a wiring conductor of the variable resistor. The stick lever unit includes a fixing member, a first variable resistor attached to the fixing member, a first rotational member rotatably journalled to the fixing member for rotationally controlling the first variable resistor, a second variable resistor attached to the first rotational member, and a second rotational member having a stick lever and being rotationally journalled to the first rotational member to rotationally control the second variable resistor. The wiring conductors of the second variable resistor are derived out from the lead-out hole in the rotational shaft of the first rotational member, which is attached to the second variable resistor.

  • Patent number: 7250844
    Abstract: A stick lever unit for a radio-controlled device that is capable of easily changing the type of stick lever holding mechanism by a user is provided. The stick lever unit includes a fixing member to which a variable resistor is attached, a rotational member equipped with a stick lever, the rotational member being journaled to the fixing member and having an arc-shaped groove on a periphery thereof, and a pressure member bridged to the fixing member for pressing the arc-shaped groove. The pressure member has resilient plates of two types which can be suitably selected by means of an adjustment member.

  • Patent number: 7102561
    Abstract: A radio control transmitter capable of enhancing controllability of a remotely controlled unit, for example a model car includes a control unit having switches 8 for controlling the neutral positions of servos that operate based on control inputs of a throttle trigger 3 and a steering wheel 4, wherein the switches 8 are provided on a control unit 10 that rotatably supports the steering wheel 4, corresponding to a mount 2a of a main body. The control unit 10 is detachably installed corresponding to the mount 2a of the main body, while capable of being attached to a discretionary position in the direction of rotation. Accordingly, the position of the switches 8 can be adjusted to meet the needs of a user. Consequently, the user can operate the controlled unit with enhanced controllability.
