Apparatus for transferring seriatim related transferable images from sequentially spaced image-receiving areas on the member onto a surface of a moving receiver sheet. The transfer apparatus includes a mechanism which captures the lead and trail edges of a receiver sheet. A portion of the sheet intermediate the lead and trail edges is self-supporting. The mechanism moves to repetitively circulate a captured sheet along a path through a position at which such sheet is in transfer relation to a transferable image on the member. A charger is located adjacent to such position on the opposite side of the sheet from the member to effect transfer of the transferable images. The movement of the mechanism is synchronized with the image-receiving areas on the member to sequentially register the captured sheet accurately with the related transferable images at such position so that the images are transferred to such sheet in accurate superimposed register.

An improved receiver sheet transport in apparatus for transferring related transferable marking particle images seriatim, from spaced areas on a member, onto a receiver sheet. The apparatus successively moves a receiver sheet into transfer relation with each of the related transferable images on the member. The receiver sheet is attached to the apparatus so that a portion of the receiver sheet intermediate the lead and trail edges is self-supporting. When such self-supporting portion of the receiver sheet is in transfer relation with the related transferable images on the member, transfer of such related images onto the receiver sheet in accurate superimposed register is effected. The apparatus includes a sheet positioning member, operatively associated with an area on the member, for positioning such lead edge of the receiver sheet relative to such area to accurately align the receiver sheet with such area during image transfer.

Receiver sheet transport with alignment means

A registration mechanism registers document sheets on a copier platen at an edge of the platen surface. The mechanism includes a unique gate member that moves relative to the platen edge to either register a document sheet or to permit the sheet to be driven past the edge and over a sheet deflector. For duplex copying, the deflector can be raised to guide the leading edge of the sheet over the platen edge as the sheet is returned to the platen for copying a second side of the sheet.

Registration mechanism

An improved apparatus for reverse buckle feeding of sheets seriatim from a sheet supply stack. The sheet feeding apparatus includes a feed roller, mounted for rotation about a longitudinal axis. The feed roller has a frictional sheet feeding peripheral surface in juxtaposition with one of the sheets of such stack. A second roller is mounted for rotation within the feed roller about a second axis which is parallel to the longitudinal axis of the feed roller. The second roller has a frictional sheet engaging peripheral surface, a portion of which extends through an opening in the peripheral surface of the feed roller radially beyond such surface. The second roller acts to urge the engaged sheet in the direction opposite to the feed direction. The feed roller and the second roller are simultaneously rotated in opposite directions about their respective axes, whereby the sheet engaging surface and the sheet feeding surface sequentially engage each sheet of the stack to first separate (buckle) and then feed the same from the stack. The apparatus may further include means to facilitate unimpeded movement of a fed sheet, relative to the sheet feeding surface, once the fed sheet is moving under the influence of a downstream transport. Such means also acts to prevent premature feeding of subsequent sheets.

A convenience copier is provided with the capability for producing duplex, collated copies in page-sequential order, or an approximation thereof. The copier includes a processing section for establishing visible representations of the original, feeding sections for presenting the original sheets and copy sheets to the processing section on a one-original-sheet one-copy-sheet basis, and inverting means for presenting both faces of the original sheets to the processing section for copying and both faces of the copy sheets to the processing section for receiving the visible representations. The original sheets are circulated to the processing section in a manner suitable for producing collated copies and inverted with each circulation in a manner suitable for producing the copies in page sequential order.
