ABSTRACT:
Releasable device for fastening a unitary typewriter print head or other printing device to its mounting are disclosed. A manually-operated control lever on top of the print head effects the closing or opening of a pair of locking levers, to engage them with or release them from a retaining groove in the mounting post. The locking arms are displaced toward or away from the retaining groove by cam action in the form of journal bearings in the control lever, which are rotated in a conical path with respect to the pivot axis of the lever.
