Abstract
A reader printer apparatus includes a modular housing formed by structural foam molding which includes an integrally formed means for carrying the various components of a reader printer apparatus. By providing an integrally formed carrying means, the need for a separate metal chassis and brackets is eliminated, thus reducing the number of parts required. Additionally, this allows the weight of the machine to be reduced to a value less than the seventy pound limit to enable the machine to be shipped by relatively less expensive small package carriers. The reader printer apparatus in accordance with the present invention includes a scanning assembly located relatively close to the object plane in order to reduce the overall size of the machine. Moreover, by locating adjacent scanning assembly adjacent to the object plane, the optical paths for the printing mode and the viewing mode are virtually independent, thus obviating the need for pivotally mounted viewing mirrors. The scanning assembly includes a pivotally mounted print mirror driven by a stepper motor synchronized to the speed of the print engine by a stepper motor, mechanically independent from the print engine. This reduces distortions in prints due to wear and voltage fluctuations relative to the print engine.
