Abstract
A print element shifting apparatus has a cam (32)
movable in an arc for locating a print element (10) in either
of two operating positions. The cam is movable by a crank
arm (42) also movable in an arc between two limit positions.
The driving connections between the crank arm and the
cam is effected through a pin-and-slot arrangement such
that there is driving contact between the crank arm and the
cam intermediate the two limit positions, and virtually no
driving contact at the two limit positions, so that vibration of
the crank arm is not transferred to the print element.
