ABSTRACT:
A ramp ribbon cartridge adapted for ramp mounting of a ribbon in a printer device which comprises a cartridge housing having a first end and a second end, a ribbon stored in and extending from the cartridge housing and on which a printing head makes a printing track while printing, a drive wheel for pulling the ribbon out of the housing, with the drive wheel being rotatably mounted at a first end of the cartridge housing and being adapted to connect with a drive shaft in a printer device, a ramping mechanism between the cartridge housing and positioned near the second end of the housing so as to place the ribbon at a ramp angle to the horizontal, a loose fitting connection between the drive wheel and the drive shaft of the printer device so that the drive shaft still drives the drive wheel without binding when the drive wheel is tilted on its axis away from the vertical, whereby the printing track of the ribbon is at a ramp angle to the top and bottom edges of the ribbon and is wider than if the ribbon were positioned in a horizontal attitude.
