ABSTRACT:
A device for use with a copier to make copies of both sides of a document or other objects in a single pass. The device is configured to rest on a copier platen without being attached to the platen and without deriving power from the copier. A document holder in the form of a pair of plates joined by a hinged connection is opened for insertion of a document to be copied. The holder is pivotally attached to a base member and spring-biased to rotate from a first to a second position above the copier platen. As a copier scanner moves beneath the holder temporarily latched in its first position, a first side of the document is scanned. A sensor then causes automatic release of the holder permitting it to swing to its second position for scanning its second side as the holder moves to its second position.
