Abstract

Print hammers 13 of this printer are fired twice in one print cycle (over-printing) to achieve printing of Japanese Katakana which has Japanese accent '' '' or'' " 1'. Two groups of one hundred and twenty different type members 10 are uniformly spaced on an endless chain belt 11. They are movable at a constant speed in a continuous path and along a print line. Type members 10 include Japanese Katakana body characters, Kanji characters and Japanese alphanumeric characters.

Katakana Printer

Print hammers 13 of this printer are fired twice in one print cycle (over- printing) to achieve printing of Japanese Katakana which has Japanese accent '' '' or'' " 1'. Two groups of one hundred and twenty different type members 10 are uniformly spaced on an endless chain belt 11. They are movable at a constant speed in a continuous path and along a print line. Type members 10 include Japanese Katakana body characters, Kanji characters and Japanese alphanumeric characters.

Uniformly spaced print hammers 13 are located along the print line. They selectively strike type members 10 as the latter become aligned at predetermined hammer positions. Members 10 are spaced at each of the print positions occurs in a plurality of successive alignment sequences or subcycles.

Character counter CC is for tracking the various members 10 and generating coded signals of members 10 which are alignable with a portion of hammers 13 during the subcycle. Coincidentally with the tracking of members 10, storage device 14 is scanned by readout drivers 15 and 16 to produce a second set of signals. These indicate the data to be printed at the various print positions of each subcycle.

The two sets of signals are fed to compare circuit 42. The output of circuit 42 is connected to a hammer selection matrix 17. This gates an identity compare pulse to the appropriate hammer firing network and storage 18.

In order to achieve the printing of one hundred and twenty different type m...
