Digital scanning of document sheets with a substantially vertical scanning system is provided by sequentially feeding the uppermost document from an upright input loading and image viewing area to a scanning head, and then to an output, along a sheet feeding path which is substantially linear, planar and vertical, but also somewhat rearwardly inclined, defined by a correspondingly rearwardly inclined document rear supporting surface and a substantially horizontal bottom edge supporting surface providing a lateral movement guide and at least initial gravitational registration and support of the bottom edges of the loaded documents. The scanned documents can be automatically ejected to stack in the collated order in which they were fed to be scanned by automatically deflecting them forwardly (outwardly) from their substantially vertical rearwardly inclined lateral movement path onto a forwardly inclined stacking area.

Automatic document scanner with upright visible document images

A document handler, such as used in a digital copier, includes an input tray and an output tray, connected by a paper path. Along the paper path are disposed two scan heads, one to record image data from each side of the sheet. The two scan heads are separated from each other along the paper path by a pitch length longer than a sheet to be scanned. The arrangement allows an image on each side of the sheet to be scanned at an exclusive time. For long sheets, a recirculation path, associated with the paper path, is used to allow the sheet to re-enter the paper path: in this way, one side of the sheet is scanned with one scan head, and then the other side is scanned with the other scan head.
