Abstract

PURPOSE: To provide the subject printer which can print at a high speed by means of a less number of printing elements and at a reduced load applied to a drive part, by a method wherein a plural number of pointed projection streaks are formed in parallel to its axis on an outer circumference surface of a platen, and a plural number of thin laminar members are attached under special conditions.
CONSTITUTION: A plural number of narrow pointed projection streaks 8 are formed in parallel to an axis of a platen 3 on the external surface of the platen 3. A plural number of thin hammer members 18,19, which record a dot on a record paper on the projection streaks, are mounted in parallel in the scanning direction of the record paper at an inclining angle to the feed direction of the record paper. The inclining angle Θ of each of the hammer members 18 and 19, a distance D between the hammer members placed in parallel, and a scanning speed V of a printing head are determined into the conditions which satisfy or approximately satisfy equalities I, II, and III, respectively, (where M is the number of the hammer members; N is the number of the projection streaks on the platen; Ph, Pv are a pitch in a lateral direction of a dot matrix and a pitch in a longitudinal direction of a dot matrix, respectively; Q and f are that which is individually represented by the formula IV.
