Abstract

A paper alignment device for a printer, typewriter or like office machine comprising a friction drive for advancing a sheet of paper in opposite directions past a printing head wherein an alignment mechanism is adapted to co-act with the friction drive to align the sheet of paper from the time when it is about to be released from the friction drive until it has been released and also for generating a force to return the sheet to renewed engagement with the friction drive when the latter has been stopped in preparation for drive of the sheet in the opposite direction.
