Filed:

Jul 26, 1974

Appl. No.:

5/492175

Inventors:

Robert H. Townsend - Richardson TX

Assignee:

Xerox Corporation - Stamford CT

International Classification:

G03G 1510

US Classification:

355 10

Abstract:

A xerographic apparatus having an improved liquid developer applicator is disclosed. The liquid developer applicator comprises a hollow, cylindrical, deformable fluid dispensing sleeve member having an outer elastomeric layer characterized by an outer surface having a relief pattern for carrying fluid developer provided from a reservoir to a photoconductor surface. The hollow, cylindrical, deformable fluid dispensing sleeve is also characterized by multiple inner layers which are provided to impart desirable properties and characteristics to the sleeve member. The fluid developer applicator is particularly useful in developing latent electrostatic images on photoconductor surfaces.

US Classification:

235485

Abstract:

A tracking mount assembly is provided for use with an electronic typewriter magnetic card support platform having a top surface and a card guide surface thereon. The tracking mount assembly includes a bridge frame with a lead screw and a guide shaft mounted in the frame. A pair of lugs extend from the frame and are formed with alignment surfaces thereon. The alignment surfaces of the lugs engage the card guide surface of the card support platform to align thelead screw and guide shaft relative to the card guide surface. The lead screw and guide shaft are further aligned relative to the plane of the top surface of the card support platform by the connection between the bridge frame and the card support platform.

International Classification:

G03G 1500

US Classification:

355 3R

Abstract:

An electrostatic reproduction machine with photosensitive member on which latent electrostatic images of an original being reproduced are made following charging of a photosensitive member, the images being developed or transferred to a sheet of copy paper which is thereafter fused to form a permanent copy. A transparent platen supports the original with one or more relatively low power flash lamps being provided to illuminate the original resting on the platen. The light image produced is transmitted by an optical system to the photosensitive member to discharge the same selectively in accordance with the original. A movable optical system is provided to permit the light image to be projected onto the photosensitive member more than once in accommodation of the relatively low power of the flash lamps.

US Classification:

Abstract:

A magnetic card drive assembly for use with an electronic typewriter is provided for driving a magnetic card supported on a platform with a top surface and a card guide surface thereon. The magnetic card drive assembly includes a drive wheel supported for rotation on a frame. The frame has an alignment surface formed thereon for mating with cooperating alignment faces of a pair of lugs extending from the card platform. The engagement of the alignment surface of the drive wheel frame against the alignment faces of the lugs automatically aligns the frame and the drive wheel relative to the card guide surface. The drive wheel is further alignable relative to the plane of the top surface of the card platform by adjustment of one of three retaining screws connecting the drive wheel frame to the card platform. This screw cooperates with a compression spring acting between the frame and the card platform to position the periphery of the drive wheel tangent to the plane of the top surface of the card platform.

Abstract:

An electrostatic reproduction machine with photosensitive member on which latent electrostatic images of an original being reproduced are made following charging of a photosensitive member, the images being developed or transferred to a sheet of copy paper which is thereafter fused to form a permanent copy. A transparent platen supports the original with one or more lamps being provided to illuminate the original resting on the platen. The light image produced is transmitted by an optical system to the photosensitive member to discharge the same selectively in accordance with the original. A movable optical system is provided to permit the light image to be projected onto and in synchronism with the moving photosensitive member, in accommodation of the relatively low power of the flash lamps.

Appl. No.:

5/512580

Inventors:

Robert H. Townsend - Richardson TX

Assignee:

Xerox Corporation - Stamford CT

International Classification:

B65H 506

US Classification:

271274

Abstract:

A magnetic card transport subsystem for an electronic typewriter comprises a reversible drive roll and a coacting pinch roll which form a nip through which a magnetic card is passed. The drive roll and pinch roll coact to move the card in opposite directions. The pinch roll is so mounted that it can rock and be self-leveling to permit the full width of the pinch roll to engage the card and uniformly distribute pressure thereto. A mechanism for adjusting the pinch roll for alignment purposes is also provided.

Abstract:

A magnetic card transport system for use with an electronic typewriter includes a magnetic head assembly mountable on a bridge frame having a lead screw and a guide shaft mounted thereon. The magnetic head assembly includes a magnetic head attached to a head support. The head support is connected by leaf springs to a thread receiving structure having threads and adjacent guideways formed along an axis transverse to the longitudinal axis of the magnetic head. A clamp member is attached to the head support for engaging the threads against the lead screw and the guideways against the guide shaft whereby the magnetic head is automatically aligned relative to the lead screw and the guide shaft. The magnetic head is adjustable relative to the head support about the roll, pitch and skew or azimuth axes. The leaf spring attachment between the head support and the thread receiving structure permits resistive movement of the magnetic head relative to the lead screw and guideway.
