A document copier for producing photocopies from a book or equivalent bound volume, wherein a scanner housing (16) has a wedge-shaped surface with a window (18) in one face, and is mounted above a V-shaped book support (20) with provision for vertical relative movement therebetween so that a page of an open book on the book support can be located against the window. The scanner within the housing is movable to relay strip images via an optical system including reflector devices and a lens onto a photo-sensitive surface moved in synchrony with the scanner, the optical path length being kept constant (FIG. 1). |
