Abstract
A printing apparatus having a daisy-shaped type wheel which is equipped with a multiplicity of radially disposed type element holders each carrying at its outer end a type element. A printing head comprising the type wheel, an electric drive motor coupled to the type wheel, a print hammer and a ribbon cartridge, is pivoted, with a simple manipulation of a manual lever, from its lower, normal operating position to its upper non-operating, about 45.degree.-from-horizontal position at which the type wheel is mountable on, or removable from, the end of a rotor shaft of the motor in an axial direction thereof, without interference with a platen, and with the ribbon which is put out of the mounting and removing path of the type wheel when a platform on which the cartridge is mounted is pivoted to its upper position together with, and by larger amount than, the printing head due to the manipulation of the manual lever. A difference in angle of pivoting movement between the printing head and the platform causes a pair of ribbon holders to move upward carrying an active portion of the ribbon supported therebetween to the upper position at which the ribbon is clear of the type wheel to be removed or mounted.
