A sheet registration system for a sheet handling device has a plurality of driven belts. Each belt is entrained about a driven roller and an idler roller. The driven rollers are fixedly mounted on a common drive shaft that is connected to a motor. The idler rollers each have a shaft and the idler shafts are coaxially aligned and parallel to the common drive shaft. Adjacent idler shafts are interconnected. The idler rollers are cantilevered about the common drive shaft and may be pivoted thereabout. The gravitational force on the cantilevered idler rollers provide the normal pressure on the belts to produce the frictional force necessary to acquire and register incoming sheets. Selective pivoting of the idler rollers in response to sheet media parameters inputted to a control panel by an end user automatically varies the normal pressure of the idler rollers and adjusts the frictional force of the belts.

A fuser module for a compact printer or copier includes therein a decurler which shares a common drive means with the fuser rolls. The decurler comprises a set of deformable rollers disposed on a decurling roll, the total length of deformable rollers being less than 25% of the effective length of the decurling roll. The module pivots open for jam clearance from either the fuser rolls or decurler.

In a reproduction machine, a static elimination device for removing static charge from a sheet of material being conveyed along a sheet path through a sheet handling machine. The static elimination device includes a thin flexible support member having a first length suitable for spanning across the sheet path, and a first width defining an area with the first length for supporting a static charge removing member. The static charge removing member has a second length substantially equal to the first length of the support member, and a second width greater than the first width of the support member, and is mounted to the support member. In particular, the static removing member comprises a conductive fabric for mounting in a static removing relationship with a sheet being conveyed along the sheet path of the sheet handling machine. The fabric consists of innumerable thin fibers forming fabric segments. Each thin fiber has a conductive plating, and each segment of the fabric includes a non-woven innumerable number of the thin fibers forming a compressed, and bonded pile having highly random orientations of individual fibers.

In a reproduction machine, a user clearable convenience stapler assembly. The convenience stapler assembly includes a stapling apparatus having a stapler head for stapling together a set of copy sheets, and a mounting assembly for mounting and supporting the stapling apparatus to a portion of a frame of the reproduction machine. The stapling apparatus is mounted and supported such that staple jams within the stapler head are clearable by an ordinary user of the reproduction machine. The mounting assembly includes a pivot plate sub-assembly for mounting to the stapling apparatus, and a support sub-assembly for supporting the pivot plate sub-assembly and the stapling apparatus in a stapling position and in a jam clearing position. The pivot plate sub-assembly has integrally formed therein hinge tabs for forming part of a pivot assembly for the stapling apparatus and pivot plate sub-assembly, and a latching aperture for receiving a latching stop member from the support sub-assembly. The support sub-assembly has integrally formed therein tab claw arrangements for receiving and pivotably retaining the hinge tabs of the pivot plate sub-assembly, a latching stop member for latching the pivot plate sub-assembly through the latching aperture, and spring members for retaining the pivot plate sub-assembly and the stapling apparatus in the stapling position and jam clearing position, thus allowing an ordinary user of the reproduction machine to safely and easily pivot the stapling apparatus and pivot plate sub-assembly into the jam clearing position.

Reducing the operating impact noise of a moving bins sorter of the type in which the bins of the sorter are sequentially incremented with a rotatable open mouthed 'C' cam drive, where the open ends of the 'C' cam on opposite sides of the open mouth provide operative bin engaging cam surfaces for engaging a cam engaging portion of the bins, without adversely affecting the contacting surfaces wear rate, by providing cantilevered arms of limited flexibility supporting the bin engaging end portions of the 'C' cam to provide limited flexing of at least one of the bin engaging end portions of the 'C' cam when at least one of these bin engaging end portions operatively engages a bin, for impact noise reduction. The 'C' cam may further include an internal chordal cross brace. The 'C' cam may further include undercut or relieved areas to make the cantilevered arms thinner adjacent the bin engaging end portions, and/or a highly resilient donut shaped member mounted internally of the open mouth of the 'C' cam and positioned to partially engage the cam engaging portion of the bin entering the open mouth of the 'C' cam.

In a reproduction apparatus outputting copy sheets via exit rollers to be stacked in an adjacent stacking tray, which exit rollers are also reversible to feed a selected copy sheet still in the nip back into the reproduction apparatus to be further processed, the previously outputted and stacking copy sheets are prevented from being recaptured by these reversed rotation exit rollers, by automatically interposing a one-way gate or trap and baffle between the stacking copy sheets and the exit rollers, to prevent accidental reacquisition of those sheets into the reversed rollers, but which gate or trap is automatically deflected out of the way of a sheet being outputted from the nip of the exit rollers by the outputted sheet itself, without requiring any other actuating mechanism. Preferably this is a deflectable portion of a unitary shield member, with a sheet edge catching lip on top thereof positioned and adapted to ride against the bottom of the selected sheet being reverse fed, to catch the edge of, and deflect into an integral concave sheet edge trap, any other sheet being dragged back with the selected sheet towards the nip of the rollers. Preferably an arcuate baffle portion also extends outside of the periphery of the bottom exit roller, which may also be so deflectable.

An optical scanning system for a compact copier wherein a scanning carriage is reciprocated beneath a platen containing an original document to be copied. The drive system for the carriage includes a cable which moves the carriage through its scan cycle while continually exerting upon the carriage a biasing moment sufficient to neutralize undesirable carriage force couples associated with high scanning rates.
