ALL-POINTS ADDRESSABLE DOT PRINTER |
摘要 |
<p>An all-points addressable dot printer has rows of sloped parallel anvils on a rotating drum. Alternate rows slope in opposite directions for bidirectional printing with a single row of hammer blades. The blades which are spaced apart, are shifted bi-directionally in synchronism with the scanning motion of the anvils to print dots at all dot line points. A second embodiment has a reciprocating comb bar located between the blades and a print medium. Spring fingers on the comb bar have dot forming protrusions. The spring fingers are uniformly spaced with center spacing equal to the center distances between the blades. Comb bar motion is linear with time along the line segments. Blade motion is simple harmonic. EN978026</p> |
