摘要： The present invention relates to an electronic illumination apparatus which may be used in audio equipment. The electronic illumination apparatus allows recognition of the position of rotational operation of a knob by the light from a built-in light emitting diode. The object of the present invention is to provide an illumination type electronic part of rotational operation which is readily adaptable to changes in specifications for the rotational operation shaft. The disclosed apparatus also is able to withstand a strong thrust force applied to the rotational operation shaft, to reduce the hitting sound emitted from the rotatable stopper of the rotational operation shaft, and also to light up the illumination means disposed on the end of the rotational operation shaft in a stable manner. In order to achieve the foregoing object, the rotational operation shaft is made in a simple hollowed cylindrical shape, and the rotor having a stopper for restricting the extent of its rotational motion is prepared separately from the rotational operation shaft, preferably by resin molding. More preferably, the rotor is made of a transparent resin and integrally molded together with the light collecting lens for the light emitting apparatus.

摘要： A potentiometer includes a rotatably mounted lever which acts as a follower member adapted to lie in contact with a moveable finger, the movement of which the lever is to follow, the lever being biassed at all times towards the finger by resilient return means.The lever is in the form of a fork having two arms whereby it is adapted to embrace the finger. Whichever one of these arms is in the trailing position with respect to the direction of rotation in which the lever is biassed by the return means is longer than the other arm. In the embodiment described, the longer arm is an active arm, the shorter arm being a security arm.

摘要： A torque takeout mechanism for a rotary electronic part, such as a potentiometer, comprises a first rotor capable of rotating with the rotating shaft of the electronic part, a second rotor engaging with the first rotor, a flat plate disposed between the first and second rotors, a spring member resiliently sandwiched between the first rotor and the flat plate, and an O-ring made from rubber and resiliently sandwiched between the second rotor and the flat plate. The flat plate is held to the body of the electronic part so as not to be rotatable with the rotating shaft, but the plate is movable lonitudinally of the rotating shaft.

摘要： A potentiometer comprises a housing having a resistance element disposed therewithin, a spur gear rotatably housed within the housing and drivingly engaged with a worm gear that is rotatably supported by the housing for rotating the spur gear when such worm gear is externally turned. A resilient wiper assembly carried by the spur gear for rotation therewith sweeps the resistance element and applies a resilient force to the spur gear to urge the latter in a direction away from the resistance element. The spur gear has a toothless area defined at a portion of the toothed periphery thereof which corresponds in position to one end of the resistance element. The toothless area has a tapered face engageable with the worm gear to displace the spur gear in the opposite direction against the resiliency of the wiper assembly when the wiper means is brought to the end of the resistance element wherefore the spur gear can be disengaged from the worm gear.

摘要： A variable resistor for use in a frequency regulator comprises an actuator having an intermediate portion pivotally supported by a casing, and a pair of opposite actuating end portions exposed from the casing. A pair of opposite feed pawls depend from the actuator to engage a rotor pivotally supported by the casing between the opposite feed pawls. The rotor has on peripheral edges thereof teeth meshing with the feed pawls, and carries a slider. A resistor base plate is mounted on the casing and has an arcuate resistor layer facing the slider of the rotor. The actuator is angularly movable in response to depression of one at a time of the actuating end portions thereof for turning the rotor in one direction through meshing engagement between the feed pawls and the teeth to thereby cause the slider to slide on the arcuate resistor layer. Therefore, the resistance of the variable resistor can be varied simply by pushing the actuator angularly back and forth. The variable resistor also includes a first light-emitting element for indicating operation of the variable resistor and a second light-emitting element for indicating an angular position of the rotor.

摘要： A device is disclosed for use with adjustable rotary controls such as potentiometers that have a push and/or pull feature to provide a means for locking the control knob and to provide varying amounts of drag force to aid in fine adjustments. A locking shoe assembly having integral locking shoes with cam surfaces is attached to the control panel with the rotary control shaft extending through its center. A locking knob with internal cams fits over the locking shoe assembly and is held in place with an annular retention ring. A control knob with an integral land surface is attached to the rotary shaft and extends into the locking shoe assembly. Rotation of the locking knob engages the various cam surfaces thus binding the land surface and the control knob.
