Abstract
Abstract A book copier including a cabinet having an upwardly opening exposure aperture with illuminating means within the cabinet trained into the aperture and an optical system for scanning the aperture and transmitting an image therefrom to a copy element, has a carriage reciprocably mounted thereon to transport an original to be scanned across the aperture, and means for driving the carriage reciprocably comprising a coupling rack reciprocable with the carriage and respective driving gears alternatively operable on the rack to drive it and thereby the carriage in respective opposite direction. An electrically operated means controlled by the copy element synchronizes operations and the driving means with movements of the copy element past an exposure aperture. A multiple copy selector is arranged to be manually set to control the driving means for repeating reciprocations of the carriage for production of multiple copies and the carriage cycles the selector means by a trip arm on the carriage operating a selector cycling lever system.
