Enlarged pattern generator
First Claim
1. Apparatus for enlarging an original pattern on a dot matrix comprisingmeans for defining four matrix positions corresponding to each dot included in said original pattern, andmeans for examining each dot included in said original pattern to determine whether three of the eight matrix positions adjacent to and surrounding said dot included in said original pattern are all unoccupied by dots belonging to said original pattern, said three positions being above, left-above and at left of said dot, or above, right-above and at right of said dot, or below, left-below and at left of said dot or below, right-below and at right of said dot.

Abstract
An enlarged pattern generator generates an enlarged dot matrix pattern from an original dot matrix pattern by providing up to four mutually adjacent dots. Presence and absence of neighboring dots are examined regarding each dot in the original dot matrix pattern in order to determine whether less than four dots should be provided in the enlarged pattern corresponding thereto.

1. Apparatus for enlarging an original pattern on a dot matrix comprising
means for defining four matrix positions corresponding to each dot included in said original pattern, and means for examining each dot included in said original pattern to determine whether three of the eight matrix positions adjacent to and surrounding said dot included in said original pattern are all unoccupied by dots belonging to said original pattern, said three positions being above, left-above and at left of said dot, or above, right-above and at right of said dot, or below, left-below and at left of said dot or below, right-below and at right of said dot.

5. A method of enlarging an original pattern on a dot matrix comprising the steps of providing a dot with eight surrounding adjacent positions
defining four matrix positions in a quadrangular formation each corresponding to each dot included in said original pattern and three of the surrounding adjacent patterns, and placing a dot at each of said four matrix positions except where three mutually adjacent ones of the eight positions adjacent to and surrounding a dot in said original pattern are unoccupied.
