Abstract
A document processing system includes a feeder stage for feeding documents and a transport stage downstream of the feeder stage for receiving the fed documents. The transport stage includes a document transport track defining a document transport path along which the documents are conveyed. The transport stage further includes an image camera located along the document transport track for performing document imaging. The document transport track includes a camera window at the image camera to allow the image camera to view passing documents. The camera window is positioned proud into the document transport path to facilitate wiping of the camera window with the passing documents.
Claims12
A document processing system, the document processing system comprising:
- a feeder stage for feeding documents;
- a transport stage downstream of the feeder stage for receiving the fed documents, the transport stage including a document transport track defining a document transport path along which the documents are conveyed, the transport stage further including an image camera located along the document transport track for performing document imaging, the document transport track including a camera window at the image camera to allow the image camera to view passing documents;
- wherein the camera window has a generally planar top that is positioned proud into the document transport path to facilitate wiping of the camera window with the passing documents and an upstream side of the camera window is chamfered to define a lead-in angle with respect to the generally planar top so as to avoid upsetting the passing documents, and wherein the camera window, including the lead-in angle thereof, are unitary and consist of the same material.
An imager assembly for use in a document transport, the document transport including a document transport track defining a document transport path along which the documents are conveyed, the imager assembly comprising:
- an image camera located along the document transport track for performing document imaging, the document transport track including a camera window at the image camera to allow the image camera to view passing documents;
- wherein the camera window has a generally planar top that is positioned proud into the document transport path to facilitate wiping of the camera window with the passing documents, wherein an upstream side of the camera window is chamfered to define a lead-in angle so as to avoid upsetting the passing documents, and wherein the camera window, including the lead-in angle thereof, are unitary and consist of the same material.
A method of configuring a document processing system, the document processing system including a feeder stage for feeding documents, and a transport stage downstream of the feeder stage for receiving the fed documents, the transport stage including a document transport track defining a document transport path along which the documents are conveyed, the transport stage further including an image camera located along the document transport track for performing document imaging, the document transport track including a camera window at the image camera to allow the image camera to view passing documents, wherein the camera window has as generally planar top, the method comprising:
- positioning the camera window proud into the document transport path to facilitate wiping of the camera window with the passing documents;
- and
- providing an upstream side of the camera window with a chamfer to define a lead-in angle with respect to the generally planar top so as to avoid upsetting the passing documents during operation of the document processing system, and wherein the camera window, including the lead-in angle thereof, are unitary and consist of the same material.
