摘要： A sheet guide mechanism, for use with a printer having a printing head on a carriage that is mounted on a carriage shaft for movement in a printing direction which is transverse to a feeding direction of a printing sheet supported by a platen, includes a sheet guide movably mounted on the carriage shaft. The sheet guide moves in the printing direction along with the printing head. The sheet guide can move in unison with the printing head without interfering with the printing operation.

摘要： A main frame (22) of a printer comprises a horizontal bottom plate (23e) and walls (23a to 23d) to form a box-shaped enclosure defining an inner space (23f). At least one of the walls is offset from the respective edge (104a to 104c) of the bottom plate to form an outer space (106) above the bottom plate (23e). A platen (8) and a carriage (10) are positioned in the inner space (23f) and fixed to the walls (23b, 23c) of the main frame (22). A controller board (3) and a power unit (4) are positioned in the outer space (106). An upper cover (13) has a top plate (13e) and walls (13a to 13d). The controller board (3) and the power unit (4) are positioned between the walls (13a to 13d) of the upper cover ( 13) and the walls (23a to 23d) of the main frame (23). The main frame (22) is formed by integral molding, and provides rigidity required for holding the platen (8) and the carriage (10), while collision or interference between the platen and the carriage (which move mechanically) and the controller board and the power unit is prevented.

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 stepping motor comprises a rotor assembly including a rotor shaft, a collar coaxially fixed to the rotor shaft, and a cylindrical permanent magnet block fixedly fitted on the collar, a yoke assembly including an inner yoke having a plurality of upper pole pieces arranged at regular angular intervals corresponding to an electrical angle of 2.pi. and a plurality of lower pole pieces arranged at regular angular intervals corresponding to an electrical angle of 2.pi., an upper outer yoke having pole pieces formed so as to extend between the upper pole pieces of the inner yoke, and a lower outer yoke having a plurality of pole pieces formed so as to extend between the lower pole pieces of the inner yoke, first and second driving coils received in a space defined by the inner yoke and the upper outer yoke and in a space defined by the inner yoke and the lower outer yoke, respectively, a base plate fixed to the upper end surface of the upper outer yoke, a flange fixed to the lower end surface of the lower outer yoke, and bearing bushes respectively provided in the central portions of the base plate and the flange to support the rotor shaft therein for rotation. The inner yoke is formed by bending the inner periphery of a single annular plate alternately in opposite directions to form the upper pole pieces and the lower pole pieces.

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.
