Appl. No.:

09/478245

Inventors:

James Gabriel Brewington - Raleigh NC
Richard Hunter Harris - Raleigh NC

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

B41J 201

US Classification:

347105, 400659

Abstract:

A thermal printing station includes a split rotary platen, which is driven in rotation to move a paper web across a thermal print head held against the split rotary platen. The split rotary platen includes a motor-driven shaft, a main platen roll driven by the shaft, and a platen roll extension, which is slidable along the shaft between a first position, in which the platen roll extension is engaged with to turn with the main platen roll, and a second position, in which the platen roll extension is disengaged from the main platen roll, being allowed to remain stationary due to friction forces arising from contact with the thermal print head. The first position is used for printing on a wide paper web, while the second position is used for printing on a narrow paper web, which extends only along the main platen roll. A clip is attached to the shaft to hold the platen roll extension in the first or second position.

Abstract:

A tilt mechanism of the type for interconnecting two members in a manner such that the two members may be moved and placed in various positions in relation to one another. The tilt mechanism comprising: an outer mandrel connected to a first member; an intermediate mandrel connected to a second member, the intermediate mandrel being movably disposed about a portion of the outer mandrel; an inner mandrel in functional connection with the outer and intermediate mandrel; a first spring functionally connected about a portion of the outer mandrel and the inner mandrel in a manner such that the first spring resists movement when moved in a first direction and releases tension when moved in a second direction; and a second spring functionally connected about a portion of the intermediate mandrel and the inner mandrel in a manner such that the second spring resists movement when moved in a second direction and releases tension when moved in a first direction.

International Classification:

B41J 360

US Classification:

400188, 400150, 271 65, 271186

Abstract:

A printer for printing on both sides of a document includes first printing document guides, through which a document is driven for printing on a first side of the document, second printing document guides, through which the document is driven for printing on a second side of the document, and transfer document guides, into which the document is driven between motions within the first and second printing document guides, with a deflector determining the printing document guide into which a document is driven from the transfer document guides. A print head is pivotally mounted between the printing document guides, being pivoted between a position adjacent the first printing document guides and a position adjacent the second printing document guides.

International Classification:

H04N 5655

US Classification:

348827, 2482781, 361681

Abstract:

A computer display includes a pivotally mounted upper housing having a display screen, a brake used to retard pivoting motion of this upper housing, and a release mechanism for releasing the brake so that the upper housing can be freely moved. The display screen is preferably a touchscreen, which is touched to indicate a selection made by the user, with the brake resisting a tilting movement of the screen as it is touched. In a first version, two brakes are used to retard motion in both directions, with a single release wheel being turned in one direction to allow rearward motion of the upper housing and in another direction to allow forward motion of the upper housing. In a second version, a single brake is released by stopping motion of a release mandrel to unwrap a clutch spring. In a third version, two brakes, operating near opposite edges of the upper housing to stop downward movement of the upper housing, provide a particularly stiff mechanism for mounting the upper housing, and are simultaneously released by turning a knob to pivot a shaft.

Abstract:

A gear drive system for a printer designed to print upon a continuous roll of paper and having a blade used to cut off printed portions of paper from the paper roll is implemented. The gear drive system consists of a drive shaft , a slip clutch , a clutch gear , a drive gear , and a staggered gear which controls the paper cutter blade. During printing, clutch allows the drive shaft shaft to slip relative to the clutch gear. When printing stops, clutch locks clutch gear which is engaged with the first portion of staggered gear and causes staggered gear to rotate until the second portion of staggered gear engages the drive gear. Staggered gear is then driven by the drive gear. A cutter blade is controlled by staggered gear , with the blade cutting off the paper as the drive gear is in reverse rotation. After the paper is cut, drive gear resumes its forward rotation, rotating staggered gear and consequently, rotating cutter blade away from the paper. After the blade has been rotated, staggered gear continues to turn, until the drive gear disengages with the second portion of the staggered gear.

Abstract:

An apparatus, system, and method are disclosed for authenticating a scanned document. Namely, the apparatus includes an ultraviolet (UV) illumination source, a photosensor array, an image processing module, and an image verification module. The UV illumination source illuminates a document having a UV image printed thereon. The photosensor array senses the UV image while the document and UV image are illuminated by the UV illumination source. The image processing module digitally processes the sensed UV image. The image verification module compares the processed UV image with a corresponding benchmark image to determine if the scanned document is authentic.
