Abstract
There is provided a combined variable resistor assembly provided with position indicator means for indicating positions of individual variable resistors by respective bright spots adapted to be moved by manipulating the associated variable resistors. This variable resistor assembly may find use mainly for electronic tuners, and with which the present states of the individual variable resistors for volume control, balance control, sound quality control and so forth can be known at a glance at the indicator means.
Claims6
A combined variable resistor assembly provided with position indicator means, comprising a panel formed with a plurality of slots, variable resistors corresponding in number to the number of said slots and mounted on said panel, slide members slidably engaged in said respective slots, said variable resistors having respective operable shafts and terminals extending straight and in the same direction, each of said variable resistors further including a brush holder rotatable in unison with said operable shaft, first pulleys secured to the operable shaft of said respective variable resistors, second pulleys paired with said respective first pulleys and rotatably mounted on the front side of said panel at respective positions spaced from the slidable span of the respective associated slide members, rope means each passed through each pair of said first and second pulleys and connected to each said slide member, a light source, and optical fibers each having one end held in the neighborhood of said light source and the other end connected to each said slide member.
