Abstract
A multi-plane scanner having a dual plane scanner with a horizontal window and a vertical window and a load cell/weigh platter weighing apparatus such that the weigh platter itself is a dual plane object with vertical and horizontal sections. The size and orientation of the planes of the weigh platter correspond to the size and orientation of the scan windows of the dual plane scanner, and each plane of the weigh platter has a transparent area (typically central), or "platter window", corresponding to a respective scan windows of the scanner for allowing transmission of scanned optical beams and optical barcode signals through each of the planes of the weigh platter. The platter is sufficiently rigid to permit accurate weighing whether the object being weighed is placed solely on the horizontal section of the platter or in part on the vertical section. The vertical and horizontal sections of the platter are sealed together to prevent passage of debris therebetween.
