Abstract: A drive mechanism for a member to be driven in one direction is disclosed. The mechanism is incorporated in an electronic typewriter and includes a clutch including a clutch spring which provides a driving connection between a small DC motor and the member to be driven of the typewriter. Means is provided which normally holds a driven member of the clutch to a particular angular position and, when the motor is energized, it releases the driven member to allow the driven member to be rotated by the motor. After a cycle of rotation of the driven member, the holding means positively stops rotation of the second element and hence of the driving member and the motor.A new and efficient ribbon feed mechanism is also disclosed which enables selective use of a carbon ribbon and a fabric ink ribbon depending upon a cassette mounted thereon.

Abstract: In a wire-dot impact type printer, a single electric motor is employed for rotating a platen provided at a periphery thereof with a plurality of ink saturated members to thereby change a color to be applied to a printing paper, as well as for rotating tractors cooperated with feed rollers to thereby transport the printing paper in a predetermined direction. A transmission mechanism for transmitting rotational movement of the motor to the tractors comprises a switch disc rotated together with the motor and having a circular periphery thereof which is half toothed and half untoothed, and a clutch composed of a first rotating disc rotated due to engagement with the toothed half portion of the switch disc and a second rotating disc capable of rotating together with the first rotating disc being rotated in one direction to thereby cause the tractors to rotate for the paper feeding operation, but prevented from rotation when the first rotating unit is rotated in the opposite direction.

Abstract: Disclosed is a serial printer comprising a carriage loaded with a printing head and moved in the horizontal direction, wherein a motor is contained in the carriage, a pinion is attached to a rotor shaft of the motor, a rack engaged with this pinion is attached onto a guide rail for movably supporting the carriage and the carriage loaded with the printing head is moved along the rack by rotating the pinion engaged with the rack by rotation of the motor.In this serial printer, the power loss of the motor due to the presence of an intermediate power transmitting member indispensable for the conventional printer, such as a wire rope, a toothed belt or a screw shaft, can be eliminated, and occurrence of troubles due to stretching or deformation of this intermediate power transmitting member is prevented. Accordingly, the capacity of moving and positioning the printing head is increased.

Abstract: A serial printer of the type employing a petal like print thimble is improved by employing a first motor for character selection in a circumferential direction of the thimble, and a second motor for selection of the vertical position of the print thimble, which has plural circumferentially arrayed sets of characters spaced vertically, by shifting the shaft of the first motor along its axis. When the second motor rotates in a second direction, it serves to advance the ink ribbon of the printer.

Abstract: A transport system for a dot matrix printing mechanism including an improved overall design for the transport system and improved designs for individual elements of the system and combinations of elements. The overall design of the present invention uses snap fits extensively throughout for ease of assembly and disassembly, integrates many previously separate parts into one-piece members, employs common part designs wherever possible, and uses single parts to perform multiple functions wherever possible. For example, the striker bar and ribbon frame of the system are combined into one piece and the ribbon cartridge is releasably mounted to the ribbon frame using one end of a latch member while the other end of the latch member is used to bias a pressure roller against the paper advancing roller. The overall design also includes a common drive train interconnected between the moving parts of the system whereby all of the moving parts can be powered by a single motor.

Abstract: A cartridge for a typing ribbon and spools for a correcting ribbon are mounted on a common frame which can tilt about a spindle. In a lowered position of the frame the typing line behind a daisy wheel is visible. The frame is raised by a first stroke to the position shown to dispose the typing ribbon over the typing point on the platen. A longer stroke raises the correcting ribbon to the typing point and this longer stroke also actuates an automatic ratchet wheel and pawl type of feed mechanism for the correcting ribbon. The two strokes of the frame are controlled by a disc comprising two cam tracks with a common part and separate parts having different degrees of eccentricity relative to the common part.

Abstract: A serial printing mechanism which employs a type wheel having a plurality of type characters has a single motor mounted on a carriage employed to accomplish plural functions. The single motor selectively rotates the type wheel to locate the predetermined type character in front of the typing position, and shifts the carriage. The carriage drive which shifts the carriage along a platen is powered by the single motor through a clutch which selectively engages the motor with the carriage drive.

Abstract: A serial impact printer 11 includes a frame 15 mounted drive motor 47 coupled to a print wheel 31 to effect rotation thereof. The print wheel 31 is mounted on a movable print carrier 29 which serially moves from print position to print position along the print line. The motor 47 is coupled to the wheel pulley 51 of the print wheel 31 through a belt 49 which is wrapped about two idler pulleys 57 and 59 located on a sub-carrier 61. The sub-carrier 61 moves one half the distance of the print carrier 29 so that during escapement motion of the print carrier 29, the belt 49 imparts no rotary motion to the wheel pulley 51 and hence to the print wheel 31. The print carrier 29 may be clamped by clamp 77 to the belt 49 to effect the return motion thereof. The motor 47 is also coupled through a clutch 127 to the line feed apparatus of the platen 23.

Abstract: A printing device comprises a motor, a conversion mechanism for converting rotation of the motor into first and second outputs, a selection mechanism for alternately supplying the first and second outputs, a type member for being supplied with the first output from the conversion mechanism, and a printing mechanism for being supplied with the second output. The printing mechanism is engageable with the type member to effect printing on a sheet of printing paper.

Abstract: A single stepper motor is utilized in a printing device to lift a print head from the surface of recording material upon the initial angular rotation of the stepper motor output drive shaft and to move the recording material within the printing device upon further rotation of said drive shaft. The print head is returned to the surface of the recording material by operating the stepper motor in the reverse direction until the output drive shaft of the stepper motor traverses an angular displacement equal but opposite to the initial angular displacement. A cam surface couples the output drive shaft of the stepper motor to a drive gear and transforms the initial angular displacement of the output drive shaft into linear motion to lift the print head from the surface of the recording material. Further rotation of the stepper motor drive shaft rotates the drive gear to move material within the printing device.
