Disposable ribbon cartridge for shorthand machines |
摘要 |
A disposable ink ribbon cartridge for use in a shorthand machine. The cartridge includes an endless loop ribbon threaded through an advancing mechanism in contact with a movable ink reservoir. The advancing mechanism advances the ribbon and also transfers ink from the ink reservoir to the ribbon. The ink reservoir is made from a reticulated foam which provides an even supply of ink over a long period of time. The movable ink reservoir and the advancing mechanism interact to minimize friction between the moving parts of the cartridge. The ink reservoir and advancing mechanism deliver consistent and even doses of ink to the ribbon throughout the life of the cartridge.
