ABSTRACT:
A development apparatus for applying toner of different colors to electrostatic images at a single development position moves translationally to align each of a series of development units with the development position. The development units are supported in a movable carriage which carriage includes a translation plate. A pinion supported by the translation plate engages a stationary rack to move said translation plate while the plate is supported by rollers resting on the floor of the apparatus. To maintain alignment of the translation plate and pinion with the rack, a pair of rollers engage one of opposite rails integral with the rack while a third roller is spring-urged toward the opposite rail urging the plate and pinion into alignment with the rack.
