ABSTRACT:
A single element print head having an apparatus for firmly and releasably attaching itself to the drive shaft of a typewriter. The body of the print head is provided with a central opening therethrough for receipt of the drive shaft. A cap is secured on the body around one end of the opening with the purpose of slidably holding a manual slide member in its guide recess and fixedly holding a base portion of a hair pin shaped spring in its holding groove. The spring has a pair of arms for firmly fastening therebetween, and for releasing the drive shaft by virtue of its resilience and the action of a pair of cam surfaces. The pair of cam surfaces are formed in the bottom portion of the slide member, diverging from one end to the other end like a front portion of a bullet, for expanding the arms from each other to release the arms from the drive shaft by means of the slide movement of the slide member.
