Ink-dot printer.

摘要

In the ink-dot printer, the cross-sectional area of the one end portion (44) of each one of a plurality of needles (42) is made to narrower than that of the remaining portion of the needle (42) so that the distance between the one end portions (44) of any two adjacent needles (42) is widened to prevent magnetic ink (40) from being retained between the portions adjacent to the end faces of the one end portions (44) by surface tension when the two needles (42) are simultaneously projected from a magnetic ink curtain (41) formed in the slit of a pair of magnetic pole plates (34, 36).
