Abstract
A release type dot print head employing cores formed of a difficult-to-machine magnetic alloy containing iron and cobalt as the principal components and having a high saturation magnetic flux density. The cores are fabricated easily by processing plates of the magnetic alloy in a simple shape and are combined respectively with auxiliary cores formed of an easily workable material. Thus, the principal components of the release type dot print head can be easily fabricated and assembled.
