Abstract: An attachment for converting a moving platen copier into a fixed platen copier, wherein at least part of the moving platen is replaced by a housing (26) having a window scanned by a scanner unit (30) from which strip images, reflected from a document to be copied and which is located against the window, and relayed by reflector means (38, 40), a lens (44) and reflecting device (46) onto the photosensitive surface (22). The scanning unit and reflector means are connected to the drive from the original platen so as to be synchronously driven in a manner which maintains a constant optical path length (FIG. 2).

Abstract: A book support has a pair of platens set in a V-shape and a felxible web spanning between the platens at the base of the V-shape. The platens may be mounted so that they can move towards and away from one another to accommodate books of different sizes and/or opened at different positions.

Abstract: A photocopying device which is to be attached to a conventional photocopying machine, gives to the machine the capability of copying from bound books. The device has a V-shaped book rest for supporting a book in an open condition and a scanning head with a light source. The device can be mounted on a photocopying machine so that light from the scanning head is reflected from a page of the book back to the drum of the photocopying machine, along the same route as is taken by light travelling to the drum during conventional operation, without the device.

Abstract: A document carrier, typically for supporting a book to be copied in a document copier by location of an opened page against an inclined window in a scanner housing, which carrier comprises a pair of separate plates (26, 28) supported in a trough-like configuration by arms (27, 29) which connect the backs of the plates to a movable platform (30), springs (31, 33) being provided, preferably to act between the platform and the supporting arms, to urge the plates into their said trough-like configuration (FIG. 2).

Abstract: A document scanner includes a wedge-shaped scanner housing (16, 18), vertically movable on a main housing (10) to locate an inclined scanned window against a document resting on a trough-like document support (14) beneath the scanner housing. The scanner housing is manually movable up and down for location against and removal from a document to be copied, and counterbalancing means are provided within the main housing to facilitate such vertical housing movement.

Abstract: 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).
