DOCUMENT SCANNER WITH INSTANT RETRIEVAL PROCESS

摘要

An improved document scanner for imaging documents and decoding coded indicia such as bar codes and magnetic strips is disclosed. In a preferred embodiment, the scanner incorporates a set of emergency exit instructions so that a user can always retrieve sensitive documents at a moment's notice. These instructions include receiving an emergency exit command from a jamming sensor or from the user, and then attempting mechanical translation toward a first exit and further subsequent translation toward a second exit. If the document is not successfully retrieved, the scanner prepares for manual document extraction as detailed herein.
