    摘要： A typehead for a single element printer is rotatably supported on a support member which is pivotable to enable the print head to be rotated and tilted for positioning a selected type character for printing. Printing is effected by moving the support member from a rest position to a printing position to impact the selected type character against a cylindrical platen. To prevent smearing or blurring of the printed type character, the support member has a projecting abutment acting against a lower edge of the typehead for precluding a downward tangential movement of the typehead resulting from a component of the impacting force.

    摘要： A bichrome ribbon is carried in an upwardly biased ribbon fork for movement between a lowered position and a raised position to bring different colored portions adjacent one of a plurality of characters on a print wheel for being impacted by a platen carrying a recording medium. The print wheel is rotatably driven by a pivoting gear segment to position a selected character for printing, and the ribbon fork is normally limited to the lowered position by an armature of an unenergized control magnet which is spring biased into blocking relation with a control pawl linked to the ribbon fork. The ribbon is moved to the raised position by first energizing the control magnet to pull the armature from the control pawl, and to minimize the required strength of the control magnet the control pawl is held out of frictional engagement with the armature by a stop on the gear segment engaging the ribbon fork and holding it slightly below the lowered position when the gear segment is at its rest position. The subsequent movement of the ribbon fork to the raised position is in accordance with the movement of the gear segment, and the upward movement is limited by a stop pin engaging an end of an elongated slot in the control pawl as the ribbon fork reaches the raised position. After printing, the ribbon fork is returned to the lowered position by the stop on the gear segment as it moves to the rest position, whereupon the control magnet is deenergized to return the armature to blocking relation with the control pawl.

    摘要： Automatic shifting mechanism is provided to shift a pin matrix type head normally positioned closely spaced from a printing plane during printing to a retracted position away from the printing plane during carriage return movement of a carriage supporting the printing head. Movement of the printing head from printing and retracted positions is controlled by carriage limit position.

    摘要： Ring-shaped type wheels having type characters formed on the periphery thereof are resiliently supported on a rotatably driven shaft at a normal operating position. A type character is printed on a recording medium at a printing position by stopping the normal rotational movement of a type wheel at a point on the periphery so as to cause the rotational kinetic energy associated with the type wheel to pivotally move the type wheel to the printing position and impact the type character against the recording medium.

    摘要： The carrier lever of the ribbon fork is mounted on a control shaft to which a control lever is secured. The carrier lever and control lever have slots through which a rod operated by the universal bar of the typewriter passes. The shape of the slots is selected so that in accordance with the set angular position of the control shaft, the ribbon fork is raised from an inoperative position to at least one operative position, and then locked when the rod passes through parallel slot portions.

    摘要： The type head of a typewriter or like business machine is turned about perpendicular axes by two incremental links in order to place a character selected by actuation of a key, in a printing position. Each incremental link is placed in a plurality of angular positions by two eccentric means which are coupled or disengaged from two drive shafts under the control of electromagnetic means energized by key switches.
