Abstract

Abstract A digital printout arrangement to print out a predetermined character response to a known coded input signal. The printout arrangement has a rotatably moveable platen for moving the medium upon which the printing is to occur in both forward and reverse directions. A printhead, which may be of the dot matrix type, is mounted on a carriage that moves reciprocatingly adjacent the platen. An incremental print ribbon is intermediate the platen and printhead to allow printing on the medium in response to activation of the dot printers in the printhead. The platen, printhead and print ribbon are digitally moved in response to digital control signals. A microprocessor, which comprises, essentially, a mini, special purpose computer is provided and has a storage means, a memory means and logic for generating the digital control signals in response to known input signals. The input signal may, for example, be of the serial by bit coded type and is converted into a parallel by character coded signal. The microprocessor generates the appropriate signals for control of the various components. Position sensing means for detecting the position of various components may also be provided. The microprocessor may store in a memory various programs for specific responses to the known input signal. The carriage drive means is preferably of the linear induction motor type and the carriage is free of direct mechanical interconnection to the carriage drive means.
