<p>PURPOSE:To provide a fader unit whose state can be displayed and whose wiring operations can be facilitated. CONSTITUTION:A fader base 1 has a displaying face and a sliding groove. A roller bearing 25 is slidably held in place and a slider 22 is passed through the sliding groove and a control 23 is mounted on that portion of the slider 22 which projects from the sliding groove. A variable impedance base 31 is perpendicularly attached to the fader base 1 and two resistance patterns 32, 33 are disposed on the outside surface of the base 31 and parallel to each other along the longitudinal direction of the base, and a slider 27 is brought into contact with each pattern. A display drive base 41 is installed parallel to the variable impedance base 31. Light emission diodes 451-4510 and an IC chip 44 are mounted, respectively, on the side of the interval 40 of the display drive base 41 and on the side of the fader base 1 of the display drive base 41. A terminal portion 51 is projected from the end of the display drive base 41. The output terminals 521--5210 of the variable impedance base 31 and the display drive base 41 are provided in the terminal portion 51.</p> |
