摘要:
A roller assembly for releasably latching a roller to a drive shaft in which a cylindrical roller body has an internal bore and a one-way clutch through which the drive shaft protrudes into a recess within the cylindrical roller body, the recess retaining a spring that engages the drive shaft, and a cap having a cam fixedly rotates about the cylindrical roller body so that the cam engages and urges the spring outward releasing the drive shaft.

In a document processing array, an imaging/illumination arrangement for illuminating and imaging the documents at one or several imaging-sites as they are rapidly transported there-past, each site having, as its illumination source, a hollow Lambertian integrating cylinder housing lamps which project essentially all their light onto the inner cylinder walls to be reflected/diffused thereby in Lambertian fashion and sent to the imaging site(s).

An arrangement for illuminating documents in a document-processing system wherein a large number of documents are rapidly and continuously transported past one or more imaging stations, each station having, for illumination, an integrating structure which houses one or more cylindrical, integrating Lambertian reflecting/diffusing cavities, each cavity having one or more like light sources, so that each cavity generates and projects a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating imaging camera means and optical guide means to couple the illumination beam to the face of the documents at the imaging station and to couple the image of the document to the imaging camera.

A leak tolerant liquid cooling system for electrical components comprises a cooling circuit which contains a pump and conduits that circulate a liquid coolant past the electrical components and through the bottom chamber of a purge tank. This purge tank also has a top chamber which is connected to the bottom chamber through a passageway; and, the bottom chamber is sized such that the liquid coolant passes through it with a velocity which is low enough to let any air bubbles in the coolant rise and move by buoyancy through the passageway into the top chamber. Air is purged from the top chamber through a valved output port by forcing liquid coolant into the top chamber through a valved input port. To complete this purge quickly, the passageway between the purge tank chambers is configured in a way which hinders the flow of coolant from the top chamber to the bottom chamber while the coolant is being forced into the top chamber. As the air purging occurs, the coolant continues to be pumped past the electrical components through the cooling circuit.

A low-profile document feeding machine includes a feeder, a hopper, at least one processing device, and an output pocket. The feeder feeds documents one at a time from a document stack in the hopper for processing by the at least one processing device and reception by the output pocket. The hopper has a hopper floor including a hopper floor extension that extends beyond a footprint of the low-profile document feeding machine so as to better support longer documents. The hopper floor extension extend a to a sufficient extent such that a total length of the hopper floor is at least about 5.5 inches.
摘要:
A document processing device and method of processing documents are disclosed. In one aspect, a document processing device includes a path of travel of documents through the document processing device, the path of travel including an approximately straight portion between a document tray and a document outlet and a return path to the document tray. The document processing device also includes a magnetic ink character recognition reader placed adjacent to the path of travel, and oriented to read magnetic characters printed on a document passing along the path of travel, the document having a front surface and a rear surface. The document processing device also includes an image capture device placed adjacent to the approximately straight portion of the path of travel and oriented to capture an image of the document passing along the path of travel. A plurality of rollers at least partially defines the path of travel, and includes a drive roller configured to route documents along the path of travel. A one-way gate defines a portion of the path of travel, the one-way gate capable of cooperating with the drive roller to reverse the orientation of the front and rear surfaces of the document within the path of travel.

A compact, desktop document processor for use on a counter-top is provided. A low-profile document feeding machine includes a feeder, a hopper, at least one processing device, and an output pocket. The apparatus further includes a reversible motor including a shaft, a first one-way clutch, a second one-way clutch, a nudger device, and a jogging device. The nudger device is drivingly connected to the motor through the first one-way clutch such that driving the motor in a forward direction drives the nudger device to urge a document from a document stack in the hopper into the feeder. The jogging device is drivingly connected to the motor through the second one-way clutch such that driving the motor in a reverse direction drives the jogging device to align the documents in the document stack prior to feeding.

A hand-separable ribbon spool shaft assembly adapts a plain ribbon spool so as to provide drive and location functions. The shaft assembly is composed of at least two shaft parts that are assembled to the ribbon spool and cooperate to provide a manual hand-action locking mechanism. First and second ends of the shaft assembly provide bearing and locating surfaces when the shaft assembly is positioned in a printer. The bearing and locating services allow the ribbon spool shaft assembly to rotate during operation of the printer, and the assembly further includes a gear drive means for driving the rotating ribbon spool.

An arrangement for illuminating objects wherein a large number of objects are rapidly and continuously transported past one or more stations, each illuminated by a cylindrical, integrating Lambertian reflecting/diffusing cavity having one or more like light sources therein so as to generate and project a highly intense, highly uniform and highly diffuse beam of illumination, while incorporating optical guide means to couple said illumination beam to the face of the objects at said station and to couple the reflected image of the object back to the cavity.
摘要:
A mounting array for a planar photo-sensitive imaging CCPD disposed in a camera and adapted to facilitate both position-adjustment and securement of the CCPD in five senses, i.e. Left/Right, up/down, in/out, pitch angle and red angle; third array comprising a planar circuit board for receiving and carrying the CCPD; a pair of like threaded posts projected from the camera to penetrate through respective oversized holes in the board; two pairs of front/rear washers each adapted to adjustably affix the board on a respective post and so facilitate Left/Right, up/down and roll angle adjustment of the board in the oversized holes; the washer means also facilitating in/out adjustment of the board and, by differential-adjustment between both washer pairs further facilitating pitch angle adjustment.
