Printer with multi-tractor form shuttle










Image Number 3 for United States Patent #5139355.

A multi-tractor shuttle printer having an array of moveable tractors such that a selected tractor and form can be shuttled into, and out of, position for printing. A drive motor is linked via cable to the tractors to shuttle them into and out of position. Guide plates located on each side of the array of tractors have guide slots into which a guide rod from each tractor fits. Movement through the path of the guide slots is controlled by a pair of flippers located in each guide plate. When a tractor is driven to the engaged position, it engages a main drive gear which controls transportation of a continuous form through the engaged tractor into the printer.
