ABSTRACT:
An improved transmission system for a document feeder, in which a constant one-way-rotating gear train is mounted in an output zone so as to cause a transmission shaft in the output zone to rotate in one direction only to send out a sheet of document no matter the driving gear rotates clockwise or counter-clockwise; therefore, as soon as a first sheet of document moves out of the scanning line without moving out of the output zone, the driving gear will change its rotation clockwise so as to have a next sheet of document fed into the scanning zone; therefore, the feeding distance between two sheets of document will be reduced, and consequently the whole feeding time for a document will be reduced, too.
