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. |
