Abstract
A reversible typing ribbon cartridge has two pairs of pinch roll pairs for moving the ribbon in the direct and inverted positions respectively. When the cartridge is off the typing machine both pinch pairs are engaged with the ribbon, but as the cartridge is installed, a rod penetrates into the cartridge and disengages the pinch pair in the following position while drives engage the ribbon spool and the pinch pair in the leading position.
