摘要： A ribbon protector is used for protecting paper from contamination by an ink ribbon in a printer, where the protector is inserted between paper located between a platen and a printing head. The printing head facing the platen performs spacing movement for printing. Two connected plate-like elements are provided with through openings for passage of the pin of the printing head. Mutually engageable electroconductive elements are provided on the inner walls of the two plate-like elements, at least in the area where they are compressed by the tip of the printing head, and spacers which are made from resilient materials are located between the two plate-like elements.

摘要： A permanent magnet type stepping motor comprising first and second stator assemblies arranged coaxially about a longitudinal axis. Each assembly includes first and second ring-shaped stators made of magnetic material. The first ring-shaped stator has a central portion with an opening therein, an annular yoke surrounding the periphery of the central portion and a plurality of pole pieces distributed about the circumference of the opening and extending toward a plane transverse to the axis. The second ring-shaped stator has a central portion with an opening therein, an annular substantially planar yoke surrounding the periphery of the central portion and a plurality of pole pieces distributed about the circumference of the opening and extending away from the transverse plane so as to interleave with the pole pieces of the first stator. The central portion of the second stator protrudes from the plane of the yoke in a direction away from the transverse plane. A coil is interposed between the first and second ring-shaped stators and surrounds the pole pieces. The first and second stator assemblies are arranged with respect to the transverse plane so that the second ring-shaped stator of the first stator assembly is adjacent the second ring-shaped stator of the second stator assembly at the transverse plane thereby forming a gap between the protruding central portions of the second stators of the first and second stator assemblies. A permanent magnet having N and S poles distributed alternately about the outer circumference thereof is rotatably supported within the openings in the central portions of the first and second stators of the first and second stator assemblies.

摘要： A reinking color ribbon cassette for a printer is described. The cassette has plural, independent ink ribbons of different colors - such as the primary colors and a black color - and a ribbon feeder for driving only the ink ribbon of a selected color to perform printing through the ink ribbon of the selected color. The ink ribbons can be used repeatedly by feeding their corresponding inks by a color ink feeder. The color ink feeder is constructed of ink tanks, in which inks of the different colors are contained respectively, and ink feeding members. These plural ink ribbons, color ink feeder and ribbon feeder are enclosed within a cassette casing constructed of a lower cover and an upper cover.

摘要： A pin-tractor type paper feed mechanism is disclosed which includes feed belt with pins for feeding paper having perforations along the edges of the paper, the pins of the feed belt being engageable with the perforations of the paper. An endless film is provided between the top surface of the paper and a fixed first pressure plate so as to press against the top surface of the paper. A second fixed pressure plate is provided. The endless film and the feed belt are rotated in synchronism such that adjacent runs of the film and the belt advance in the same direction. As a result, no frictional force is applied to the top surface of the paper, and damage to the paper and improper feeding of the paper are prevented.

摘要： A gear mechanism includes a pair of drive transmission gears laterally movably disposed between a base plate and a housing provided on the base plate, and a control structure for restricting the lateral movement of the drive transmission gears. Turning force from a single driving gear is transmitted to the drive transmission gears, movements of which are controlled by the control structure. In the different embodiments, the controlled turning forces of the drive transmission gears can be transmitted to either or both of the driven gears.
