Indicator device with 2 pointers
DRIVE
January 30, 2002
The device has two pointer shafts each driven by a dedicated pointer drive and two mutually concentric scales (1,2), each associated with a separate pointer. One shaft (8) is eccentric with respect to the scales and its associated pointer (6) is an optical one with a rotatable light conductor (7) mounted radially on the eccentric pointer shaft and a light conducting system of fixed light conductors (11) leading to scale indicating segments.
