ABSTRACT:
An optical scanner weigh plate mounting apparatus which does not include fasteners requiring removal in order to gain access to the underside of the weigh plate and to a scan module within the scanner. The weigh plate mounting apparatus includes a pair of pivot arms, a load distributing member, pivot flanges for pivotally coupling the pivot arms at their first ends to the load distributing member, pivot pins for pivotally coupling the pivot arms at their second ends to the weigh plate, and a spacer between the load distributing member and a weight measuring device within the scanner for raising the weigh plate to a position flush with a checkout counter in which the scanner is installed. The mounting apparatus provides hands-free operating positions. In a closed position, the weigh plate sits substantially parallel to and above the pivot arms. In a first opened hands-free position, the weigh plate sits against a first side of the counter to expose the underside of the weigh plate. In a second opened hands-free position, the weigh plate sits against a second side of the counter to expose the scan module.
