Abstract

Many serial printers of various types use a continuous ribbon loosely contained in a cartridge. The ribbon is withdrawn from one end of the cartridge and feeds in a continuous loop, past the printing position to the other end of the cartridge where it is stuffed back into the cartridge. Various types and combinations of feed rollers and guides are used in the ribbon transport system. The life of the cartridge is dependent on the amount of ribbon it contains which is dependent on the size of the cartridge which is itself restricted by the space available within the printer in the same plane as the printhead.

Enlarged Ribbon Cartridge

Many serial printers of various types use a continuous ribbon loosely contained in a cartridge. The ribbon is withdrawn from one end of the cartridge and feeds in a continuous loop, past the printing position to the other end of the cartridge where it is stuffed back into the cartridge. Various types and combinations of feed rollers and guides are used in the ribbon transport system. The life of the cartridge is dependent on the amount of ribbon it contains which is dependent on the size of the cartridge which is itself restricted by the space available within the printer in the same plane as the printhead. The present embodiment permits the accommodation of an enlarged ribbon cartridge in a less restricted location below the plane of the printhead in a known printer, by the use of integrated tapered ribbon guides which effect the transfer of the ribbon between two different planes.

The figure shows the present complete ribbon cartridge embodiment. Arrows illustrate the ribbon transport path. For clarity the ribbon itself is not shown. It is seen that the ribbon is withdrawn from Ribbon Box 1 through Exit 2, passes around Tapered Guide 3, and, following the arrows, goes up and around Tapered Guide 4, into and through Left Flexband 5, through Nosepiece 6, through Right Flexband 7, around Tapered Guide 8, down and around Tapered Guide 9 to Stuffer Gears 10 which push the ribbon back into the box. It is readily seen that the Tapered Guides...
