Claims

[Scope of Claim for Utility Model Registration] (1) A line impact dot printer in which a shuttle mechanism reciprocates a hammer bank in which a plurality of longitudinally arranged printing hammers are provided in upper and lower two stages at regular intervals along the printing line, Upper hammer 12
One set consists of 24 hammer groups (12 lower hammers), and the pin position of each pin of the upper hammer is sequentially lowered one dot at a time starting from the leftmost hammer pin until the 12th hammer pin is reached. It is installed so that it is located 11 dots below the leftmost hammer pin, while the lower hammer is located 11 dots below the leftmost hammer pin in the vertical direction.
1 dot below the second hammer pin, and using this as a starting point, sequentially move the second and subsequent hammer pins 1 dot below.
One set is configured so that the dots are lowered downward one by one, and the printing hammers are arranged in a hammer bank so that the second and subsequent sets have the same configuration, so that 24 dot lines can be printed with one shuttle. A line impact dot printer that is characterized by: (2) In a line impact dot printer in which a shuttle mechanism reciprocates a hammer bank in which a plurality of longitudinally arranged printing hammers are arranged in upper and lower stages at regular intervals along the printing line, six upper hammers and six lower hammers are used. A set of 12 individual hammers is set, and the vertical pin position of each pin of the upper hammer is started from the leftmost hammer and is lowered one dot at a time in order, and the sixth hammer pin is the leftmost hammer pin. On the other hand, for the lower hammer, set the pin of the leftmost hammer so that it is 1 dot lower than the sixth hammer pin of the upper hammer. One set consists of the second and subsequent hammer pins being lowered one dot at a time from the starting point, and the printing hammers are arranged in a hammer bank so that the second and subsequent sets have the same configuration. A line impact dot printer characterized in that printing of a 24-dot line is performed.
