Abstract

조립이 간편하고 저전력으로도 구동이 가능한 도트 프린터 헤드에 대해 개시한다. 이 도트 프린터 헤드는 그 선단에 복수의 선단가이드공(211)이 지그재그로 형성되고 후단에 복수의 후단가이드공(212)이 동일원주상으로 배열되어 형성된 가이드몸체(210)와, 각 후단가이드공(212)을 통해 각 선단가이드공(211)에 슬라이딩 가능하게 수납되는 복수의 니이들(220)과, 선단가이드공과 후단가이드공 사이에 마련되며 각 니이들이 통과되는 복수의 센터가이드공(216)이 타원형상에 형성된 가이드판(215)과, 복수개의 니이들을 선택적으로 선단가이드공 외측으로 출몰시키는 타격수단을 구비한다. 이 도트 프린터 헤드는 센터가이드공(216)이 타원상에 배열되어 형성되고 선단가이드공(211)이 지그재그로 형성됨으로써, 니이들(220)의 조립이 간편하고 왕복이동을 원활하게 한다.Disclosed is a dot printer head which is easy to assemble and can be driven at low power. The dot printer head has a guide body 210 formed by zigzag of a plurality of tip guide holes 211 at the front end thereof and a plurality of trailing guide holes 212 arranged at the same circumference at the rear end thereof, and a rear guide hole of each of them. A plurality of needles 220 slidably accommodated in each of the front end guide holes 211 through the 212, and a plurality of center guide ball 216 is provided between the front end guide hole and the rear end guide ball and each needle passes through A guide plate 215 formed on the elliptical shape, and a striking means for selectively projecting a plurality of needles to the outside of the tip guide hole. The dot printer head is formed by arranging the center guide holes 216 on an ellipse, and the tip guide holes 211 are formed in a zigzag, so that the needle 220 is easily assembled and reciprocated smoothly.
