ABSTRACT:
A document feed-in device for an electronic typewriter comprises a lower guide member for guiding a document towards a typing line on a platen cylinder and a plate or bar member for guiding the document beyond the typing line. The plate or bar member is carried by two movable levers for moving that member away from the platen cylinder and at the same time actuating a switch for signalling the presence of the document to the electronic control means of the machine, to cause rotation of the platen cylinder so that the document goes beyond the typing line by a predetermined distance such that the top edge of the document is moved into a region in which it is engaged by the plate or bar member to permit typing in a region immediately adjacent to the top edge of the document.
