ABSTRACT:
An electrically controlled copy holder includes a face plate defining a copy support surface and a line guide extending across the face plate and slideably mounted adjacent one vertical edge of the face plate, for vertical sliding movement along the copy support surface. The line guide is attached to a motor driven endless belt mounted in a housing on the opposite side of the face plate. Electric control means are provided for maintaining the motor energized for an adjustable interval, and hence for moving the line guide a pre-selected distance.
