Abstract
The present invention provides a dot printer head which includes a plurality of cores each having a mounting portion which is contacted with a core holding face of a permanent magnet and a post-like projection for mounting an electromagnetic coil thereon. The height of the mounting portion is made relatively small while the area of the mounting portion is made larger than the area of the cross section of the post-like projection. Due to this arrangement, sufficient magnetic fluxes are provided to the cores and magnetic interference between adjacent cores is reduced.
