摘要： A feed mechanism for sheets of material or continuous webs in a printer or typewriter, comprising a pin wheel feed mechanism for the feeding of continuous webs and a friction feed mechanism for the feeding of sheets of paper as well as the webs. The pin wheel feed mechanism and the friction feed mechanism are coupled together in at least two separate units for the feeding of the webs. During feeding of the webs the frictional feed pressure is reduced compared to that prevailing during friction feed of the sheets when the pin wheel feed mechanism is inactive.

摘要： Guide means for a printer including two conductor members for guiding a paper web out of the printer. In a first position, the conductor members form a tightly fitting cover for a rectangular hole in a casing associated with the printer, where the paper web is conducted in a gap, tapering in the direction of paper advance, between the conductor members and out of the printer. In a second position of the conductor members, a rectangular opening is formed behind the members, making the paper web accessible for feeding into a tractor feeder of the push-pull traction feed type.

摘要： A pivotal guide for changing the direction of a typing ribbon in typewriters such that when raising or lowering the ribbon at the printing location relative to the printing element, transverse forces are eliminated. The guide comprises a cylindrical body having a longitudinal slot which receives an end wall of the magazine, the bottom of the slot being formed with two projecting sloped surfaces which intersect midway of the body to form a pivot axis for the body on the edge of the end wall. The body has cylindrical end surfaces confined between cover plates of the magazine to limit axial movement of the guide body and the ribbon thereon.

摘要： 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.

摘要： A printing office machine in which a movable print head is driven by a device comprising a fixed, mounted lead screw and a cooperating nut member connected to an electric motor. The nut member is rotatably mounted in a carrier frame and comprises an inner tubular member which is journalled on the lead screw. An outer tubular member is journalled on the inner tubular member. An end part of the outer tubular member bears against a flange on the inner tubular member under friction. The two members are turnably interconnected by spring means, and the free ends of the members support rotatable bearings which bear on flanks of grooves cut in the lead screw. Each bearing cooperates with the groove flank which faces the respective end of the tubular member. The drive device has a very great freedom from play, and at the same time the friction prevailing between the nut member and the lead screw is minimized.
