Abstract
Apparatus for implementing a multi-color printout capability with respect to a dot matrix printer and the like. The apparatus is comprised of an ink reservoir system which includes individual ink reservoirs for replenishing ink of a selected color from a reservoir to individual sections of ink transfer material. The sections are mounted in tandem pairs on elongated ink transfer material holding members which are reciprocally moved linearly back and forth beneath the print head and across the face of a printing medium by a solenoid actuated cam. Each reservoir is continuously in contact with respective section of ink transfer material.
Claims22
An impact printer which operates to print in a plurality of colors, on a medium, comprising:
- impact print means;
- means for providing relative movement between said print means and said medium,
- at least one flat elongated ink trnasfer material holding member located intermediate said print means and said medium;
- at least two elongated mutually separated sections of ink transfer material of selective colors collinearly arranged along the lengthwise dimension of said holding member and being operable to transfer ink in the form of printed indicia, to said medium upon actuation of said print means;
- means in contact with each said section of ink transfer material for continuously replenishing a supply of ink of a selected color to the respective section of ink transfer material;
- and
- translating means for translating said ink transfer material holding member linearly back and forth across the front of said print means;
- said translating means including a cam;
- and means for rotating said cam to at least two positions, said cam engaging said transfer material holding member causing linear translation of said member.
An impact printer which operates to print in a plurality of colors, on a medium, comprising:
- impact print means including a print head having a set of dot matrix print pins;
- means for providing relative movement between said print means and said medium;
- at least two individually movable flat elongated ink transfer material holding members located, one broad surface over the other broad surface, intermediate said print means and said medium;
- each of said holding members further including at least two elongated mutually separated sections of ink transfer material of selective colors collinearly arranged along the lengthwise dimension of the respective holding member and being operable to transfer ink in the form of printed indicia to said medium upon action of said print means;
- means in contact with each said section of ink transfer material for continuously replenishing a supply of ink of a selected color to the respective section of ink transfer material;
- and
- first and second like translating means for respectively translating said ink transfer material holding members linearly back and forth across the front of said print means, said first and second like translating means each including a cam;
- and means for rotating said cam to at least two positions, said cam engaging said transfer material holding member causing linear translation of said member.
