Abstract
Weighing apparatus is disclosed including an operating device for displacing a weighing beam arresting assembly to its arresting position, and for simultaneously effecting illumination of all of the segments of a multi-segment display device. In one embodiment, a manually operable rotatable shaft is provided having a pair of cams thereon for operating the beam arresting assembly and for operating a switch to cause illumination of all of the display segments, respectively. In a second embodiment, closing of a switch to effect illumination of all of the display segments is accompanied by the energization of a motor to displace the arresting assembly to its arresting position.
