ABSTRACT:
A multitask button, cascade illumination control panel is provided. In one embodiment, successive keying of a single reduction button sequences the system to a 98% reduction, 76% reduction, and 65% reduction, respectively, back to 1-1 reduction. The stepping of the illumination lamps indicating each reduction mode occurs immediately. However, there is a deferred movement of the lens. In other words, there will be delayed response to offset any needless dithering of the machine before the appropriate lens movement is made.
