PURPOSE:To provide the compact and inexpensive titled printer which has a quick response inspite of a simple fulcrum type magnet, by a method wherein each magnet is formed in an approximate fan, and each needle is rapidly attached to each magnet so that it gathers to a center. CONSTITUTION:A section of a core 5 of a magnet 2 is formed in an approximate sector, and an armature 15 is formed in the tapering-off shape to act as a core cover and to form its extension part so as to work as a needle securing part. In case the magnets 2 are arranged in a radial manner, the whole is reduced in an outer diameter, and the ends of the extension parts can be placed in density at a center part, and the end part can be reduced in a mass as well. |
