Modular information processing apparatus

Abstract

A modular, multi-function information processing device suitable for point-of-sale (POS) station arrangements wherein separate printer and controller components are individually housed and arranged in a stacked vertical configuration. This arrangement save space by minimizing the overall footprint of the station. The connection between these components can be easily established or terminated for performing maintenance on a particular component or subassembly. Subassemblies within the housing may be extracted without impacting the overall structure of the device or use of the other components, and additional components can be easily added. Additionally, the reliability of the apparatus and constituent components and subassemblies is further improved through the implementation of electrostatic countermeasures, including component to component grounding and automatic grounding of the entire apparatus when users insert a key into a central locking mechanism electrically connected to a common electronic and physical reference.
