International Classification:

B41J 1920

US Classification:

Abstract:

A method of effecting time-linear travel of a lead screw-driven, carriage-mounted print head during the print cycle encompassed within a predetermined period of each motor-initiated advancement thereof. This is accomplished by incorporating a predetermined maximum possible amount of built-in backlash between the threaded coupling member and the lead screw, and by utilizing a predetermined time delay before printing commences so as to compensate for the backlash. The latter is employed to minimize friction and wear due selectively to any tolerance variations in the lead screw-drive nut threads, bow in the lead screw, or misalignment thereof relative to the carriage guide rods. As a result, wear of the moving parts that produce the friction is minimized. Printing of the first indicium associated with each motor-initiated advancement of the carriage is delayed until the stepping motor not only has been accelerated up to the desired rotational speed, but until the threaded member-lead screw backlash has been completely taken up, and any kinetic energy imparted carriage bounce forces resulting therefrom have been damped. As such, the carriage (and print head mounted thereon) will always be smoothly driven and at a substantially constant speed during each print cycle, so that successively printed indicia will be uniformly spaced along each print line.

International Classification:

US Classification:

197 1R

Abstract:

A wire matrix printer includes a print head having one or more banks of a plurality of generally horizontal, vertically spaced print wires arranged parallel to each other for linear reciprocation toward and away from a recording surface by associated actuators. The print wires in each bank are of progressively varying length so that the wire associated with the actuator furthest from the recording surface is the longest and each adjacent wire is a predetermined amount shorter than the preceding wire. Outer or actuator ends of the wires define a vertically spaced and stepped array. The actuators in each bank are also in an array vertically spaced and stepped and are respectively coupled to the outer print wire ends by armatures. The inner or printing ends of the wires define a vertically spaced, nearly planar array near the recording surface, and a spaced, planar array at such surface. If there is more than one bank of print wires, the banks are angularly spaced from a line extending perpendicularly from the recording surface, and the inner ends of the wires in each bank are alternately interleaved near the recording surface.

Abstract:

An assembly for processing paper tape for data processing and communication applications. The punch and reader are in a common housing which includes a self contained chad box. The assembly has a substantially flat bottom surface thus permitting the assembly to be mounted on a table. The entire operating mechanism is arranged such that it is mechanically isolated from the housing. The punch and reader assemblies utilize identical paper drive assemblies which are mechanically linked by a rigid bar. The one drive assembly is driven from an eccentric which in turn is driven by a flexible belt coupled to a motor pulley.
