ABSTRACT:
Described is a multi-optic scanner that can detect and/or measure weight placed on its vertical plate. In one embodiment, a portion of the vertical plate is positioned under a portion of a horizontal plate so that a force exerted on the vertical plate is transferred, whole or in part, to the horizontal plate. In alternate embodiments, one or more sensors are coupled to the vertical plate for detecting a force on the plate. The sensors can be coupled to an alert, such as an audible signal, to warn an operator of a misread weight.
