Abstract: A carriage for a printer or the like comprises a movable carrier which is indexed by cooperating, sliding and stationary racks lying just beneath the circumference of an axially fixed carrier support shaft. Drive and hold latches on the carrier are spring biased into contact with respective racks. Solenoid oscillation of the sliding rack one column position causes like incrementation of the carrier. Angular rotation of the shaft moves the drive and hold latches from their racks into contact with smooth shaft surfaces, causing automatic return of the carrier under dashpot action to the first column print position.

Abstract: An endless ribbon for a wire matrix printer is pulled past the print head as the print head moves along the print line by a feed roll located at the entrance to a cassette which has an elongated gradually-expanding storage chamber which readily permits random folding of the ribbon in the chamber resulting in reduced ribbon tension and more uniform ribbon feed.
