Abstract: RA979006 BAND AND HAMMER DOT MATRIX PRINTER Described, is a printing mechanism allowing full exploitation of the potential of dot matrix printing. Dot forming elements are mounted on a carrier for transport past an array of hammers located in front of media to be marked upon. The dots or carrier are impacted by the hammers to form dots on the medium. By appropriate control of motion of the printing medium and timing of the hammer impacts, a dot may be formed anywhere on the surface of the medium. This allows unlimited character font set generation as well as special character printing for enlarged font, miniaturized font, fast rough draft copy printing, the printing of ascenders and decenders for characters and for condensed or compacted printing. In addition, the mechanism permits an all points available graphics generation system and full control for variable vertical spacing of printed elements and of variable horizontal spacing of the printed elements. Variable print element shapes, grey tone graphics printing and multi-color additive or subtractive color processes are also facilitated.

Abstract: SEGMENTED DRUM BAR HELIX PRINTER Disclosed is an improved form of a mosaic printer of the bar helix type. The helical raised threads on the printer drum instead of being continuous are broken into segments which are offset axially on the drum. This produces a significant increase in throughput by reducing waiting time for the drum to rotate a section of continuous thread into alignment with a hammer at the start of a new helical pattern.

Abstract: LINEAR MOTION PRINT ELEMENT CARRIER APPARATUS For typewriters, disk printers or similar moveable print element devices, a carrier is provided to move the print element. The carrier acts by cooperation between a lead screw, mounted in stationary supports in a nonrotating fixture, and rotatable nut members supported in the print element carrier and threadedly engaging the lead screw. A motor is provided for rotating the nuts and the motor is arranged so that the rotor of the motor, the nuts and the lead screw are arranged in concentric fashion so that the motor, nuts and carrier assembly ride back and forth on the fixed lead screw, depending upon the direction of rotation of the motor.

Abstract: A printer of the type including a platen, a bank of hammers extending in a straight line along and spaced from the platen and a continuous metal band of magnetizable material on which are mounted a plurality of print elements is provided with drive means for moving the band between the platen and the hammer bank and control means for controlling the movement of the band so that the print elements on the band move along the line of hammers. The band drive means includes a drive wheel located near one end of the hammer bank and means for forcing the band into close contact with the peripheral surface of the drive wheel. The means for forcing the band into close contact with the peripheral surface of the drive wheel can be a permanent magnet member located on the surface of the drive wheel. CT9-83-009

Abstract: A printer of the type including a platen, a bank of hammers extending in a straight line and spaced from the platen, a metal band on which are mounted print elements and drive means for moving the band between the platen and the hammer bank is provided with means for controlling the movement of the band. This band movement control means includes a guide surface extending along the hammer bank and bearing means located adjacent to one edge of the guide surface and including at least one bearing surface extending perpendicular to the guide surface. The control means also includes a permanent magnet means located adjacent to the guide surface and the bearing means and adapted to attract one surface of the band to the guide surface and one edge of the band to the bearing surface.

Abstract: A printer is disclosed in which a character forming print head is disposed on a carriage which pivots about a central point to describe an arcuate path, adjacent to which is situated an arcuate platen. The media to be marked upon conforms to the arcuate shape of the platen. The print head oscillates or reciprocates from one end of the arc to the other, and back. The arcuate path length may be varied to encompass printing in one or more coplanar stations on an arc in the plane of the print head and pivot.
