Ramp ribbon cartridge

A ramp ribbon cartridge adapted for ramp mounting of a ribbon in a printer device, comprising

• a cartridge housing having a first end and a second end,
• a ribbon, having top and bottom edges, stored in and extending from the cartridge housing and on which a printing head makes a track while printing,
• a drive wheel for pulling the ribbon out of the housing,
• said 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,
• the connection between the drive wheel and the drive shaft of the printer device being a loose fit so that the drive shaft still drives the drive wheel without binding when the drive wheel is tilted on its axis,
• a ramping mechanism attached to the cartridge housing and extending downwardly from the housing and positioned away from the drive wheel end of the housing to elevate the second end of the housing and position the cartridge at a ramp angle to the horizontal,
• 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,
• said ramping means comprising a U-shaped riser clip with a base and a pair of legs extending therefrom,
• the bottom of the legs extending beneath the housing so as to elevate the second end of the housing when placed on a horizontal carrier in a printer,
• and base connecting means connecting the base of the clip to the housing.

• a ramping mechanism attched to the cartridge housing and extending downwardly from the housing and positioned away from the drive wheel end of the housing to elevate the second end of the housing and position the cartridge at a ramp angle to the horizontal,
• 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,
• said ramp angle being such that the printing track does not leave the ribbon,
• said ramping mechanism comprising a U-shaped riser clip with a base and a pair of legs extending therefrom,
• the bottom of the legs extending beneath the housing so as to elevate the second end of the housing when placed on a horizontal carrier in a printer,
• and base connecting means connecting the base of the clip to the housing,
• said base connecting means being an ultrasonic weld between the clip base and the housing.

• 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,
• said ramping mechanism comprising a riser clip made of a synthetic plastic material that snaps into the cartridge housing,
• said riser clip being U-shaped and including a base with a pair of legs extending therefrom,
• each riser clip leg having a bend therein which snaps over a boss in the cartridge housing,
• each riser clip leg having bottom portions extending beneath the housing so that when the ribbon cartridge is placed on a horizontal carrier of a printing device, the cartridge and ribbon are placed in a ramp position.
