摘要:
An inked ribbon changeover mechanism for a printing machine, in which a plurality of inked ribbons are looped over a plurality of guide members, respectively. The guide members are carried on a movable member, which is arranged to be movable to first and second positions relative to a printing head such that a selected one of the inked ribbons is placed in an operative position in which a portion of the selected one of the inked ribbons is located in a space between the printing head and a record medium when the printing head is in a printing position.
摘要:
A dot matrix impact printer of the type which has a platen having a helical projection, a plurality of hammers arranged in the axial direction of the platen to cross the helical projection, and means for feeding an ink to the periphery of the helical projection. The platen is rotated and the hammer strikes the helical projection interposing the recording paper, so that dot matrix printing may be performed. In order to prevent the contamination of the recording paper with the ink, there is provided a separating member of resilient material along the helical projection. The periphery of the separating member is slightly higher than the helical projection, so that the recording paper is separated from the helical projection. The separating member is compressed by impacting the hammer so that the ink may be transferred to the paper.
摘要:
A device for feeding an ink ribbon for use in a printing machine in which the ink ribbon is reciprocally run by rotating reels on which the ink ribbon is wound. The device has a main drive member, two driven members, a driving force transmission member, a follower members, a spring and a movement control member and thereby providing a useful and effective device without a nonsensitive zone upon changeover of the running direction of the ink ribbon.
摘要:
A cross point type dot matrix impact printer comprising a platen and a plurality of hammers arranged in the axial direction of the platen. The platen has a helix composed of a plurality of protrusions helically provided on the periphery thereof. The hammer has a hammer head which strikes each protrusion during the rotation of the platen for performing the dot matrix impact printing.
摘要:
A printing apparatus includes a type drum the outer circumferential surface of which has a first set of type including a plurality of type faces arranged in a counter-clockwise spiral and a second set of type including a plurality of type faces arranged in a clockwise spiral. The type drum is both reciprocated and rotated in synchronous fashion by cooperation between reciprocating and rotating drive means so that the sets of type disposed on the type drum pass the positions of a plurality of printing hammers confronting the drum and adapted to perform printing by striking the type faces on the drum through an inked ribbon and recording medium.
摘要:
A printer especially suitable for printing letters and symbols on a recording media having portions of different thickness such as a bank deposit pass book foldable along a folding line. A movable platen is comprised of left and right units and a central unit which are moved toward and away from the recording medium by rotary cams and spring means so that the upper surfaces of the left, right and central units of the platen are always maintained in the same plane parallel with the running path of the printing head. Satisfactory printing can be made irrespective of the difference in the thickness of the portions of the recording medium.
摘要:
A recording medium feeding apparatus for printer is disclosed wherein a web of a recording medium is fed and taken up by a take up reel. A web feeding mechanism and a reel driving mechanism are operated through a coupling means by a spring means in which energy is stored by a common driving means.
