Abstract
The embodiments described herein provide improved scanner assemblies that include a first plastic body, a second plastic body, a movable scanning platform and a drive device. The first plastic body includes a first plurality of coupling structures, while the second plastic body includes a second plurality of coupling structures. The moveable scanning platform is positioned between the first plastic body and the second plastic body, and each of the first plurality of coupling structures is welded to a corresponding one of the second plurality of coupling structures.
Claims20
A scanner assembly, comprising:
- a first plastic body, the first plastic body including a first plurality of coupling structures;
- a second plastic body, the second plastic body including a second plurality of coupling structures, each of the second plurality of coupling structures welded to corresponding one of the first plurality of coupling structures;
