Abstract: A platen for a printer includes a tubular body section, shaft sections extending from opposite ends of the body section away from each other and coaxially with the body section and an elastic layer provided on an outer periphery of the body section. The shaft sections are smaller in diameter than the body section.

Abstract: A paper bail in a printer having a platen includes two bail levers rotatably mounted on the printer and pressed toward the platen by a spring. An elongate bail plate is formed as a flat metal sheet having a L-shaped section, one side of which extends substantially transverse to a line connecting the bail plate with a rotational axis of the bail levers. A bail roller on the bail plate is mounted thereon by an elastic member capable of permitting only axial movement of the bail roller when the bail roller is out of contact with the platen, and permitting only rotational movement of the bail roller when the bail roller is in contact with the platen.

Abstract: A printing device such as a printer of the type using a type wheel in which a carriage is loaded with a printing mechanism and movable along a carrier to allow the printing mechanism to print out data on a paper, which is wrapped around a platen. The carrier and/or the carriage is produced by press-forming a single sheet metal to cut down the production cost and the number of structural elements of the printer.

Abstract: In a sheet feeding device for a printing apparatus for feeding one sheet after another to a printing station, a stopper hook is located slightly posterior to point of contact between a platen and a roller or between two rollers brought into and out of pressing contact with each other, and a sheet fed to the printing station is stopped by the stopper hook and has its position corrected, if it has a skew, while the platen and the roller or the two rollers are out of contact with each other. Thus a sheet free from skew is pressed by the roller against the platen or the roller to enable automatic skewless sheet feeding to be effected.

Abstract: A printing machine, such as a typewriter, printer, etc., including a platen having wound thereon a sheet for printing characters and symbols thereon and provided with an automatic sheet feeding apparatus including a cassette containing a plurality of sheets automatically fed to the platen. The cassette can be inserted into or withdrawn from the sheet feeding apparatus through an opening in the front of the sheet feeding apparatus. The sheet feeding apparatus enables a sheet to be selectively fed manually, if desired, besides enabling sheets to be fed automatically from the cassette. The sheet feeding apparatus enables a paper bail to be mechanically operated in conjunction with its operation of automatically feeding sheets to the platen.
