ABSTRACT:
A typing device has a type disc which includes a plurality of bars each carrying a character and which is rotatable about an axis through predetermined angles for successively setting selected characters in a printing position. The typing device further has a hammer for impacting the bar of the selected character for pressing the selected character against a record carrier supported by a platen. The type disc carries a plurality of stops; each stop is assigned to a different character. The stops are arranged at least at two different distances from the disc axis, dependent upon the printing surface area of the associated character. The typing device further has an elastic lever, one end of which is movable into an abutting engagement with the stop of the associated character situated in the printing position. Another end of the elastic lever is connected to the hammer so that the hammer and the elastic lever are moved simultaneously by a hammer drive. The elastic lever is arranged to absorb, upon engagement with the respective stop, one part of the kinetic energy imparted by the hammer drive for reducing the force with which the character is pressed against the record carrier. The amount of the absorbed kinetic energy is a function of the distance of the respective stop from the disc axis.
