A document feeder is disclosed which can be used with glass-top copy machines. It fits such copiers, having either a stationary or a moving sheet-support. It is small, light-weight, compact and portable. It feeds the bottom-most page first from a face-up stack of sheets, and re-stacks the copied sheets, face-up, with the bottom sheet at the bottom of the new stack. It operates in excess of 25 copies per minute. Drive wheels feed the document-to-be-copied onto the copier glass and, when the wheels are reversed, remove the document from the glass into a stacking area. The removal of a document from the glass and the placement of the next document onto the glass occur during the non-copying time of the continuously-running copier. The feed/separation act upon the center of the documents. The copier can derive its driving force and energy from the copier or can have its own independent power source.
