Abstract: The cartridge for an inked ribbon comprises a casing having a magazine for housing the ribbon of the closed loop type and disposed in randomly distributed turns, and a pair of rollers for the feed movement of the ribbon. A re-inking pad is rotatable in the casing and an ink distribution roller co-operates with the pad for re-inking the ribbon. The distribution roller comprises a shaft having its ends projecting from the ends of the roller and housed for rotary and sliding movement in slots in the casing and the cover. The slots are rectilinear and have their axes co-planar with the shaft of the pad to permit movement of the roller away from and towards the pad. The distribution roller is held in contact against the pad by the tension applied to the ribbon by the rollers. The tension of the ribbon automatically regulates the contact pressure of the distribution roller against the re-inking pad and optimizes re-inking of the ribbon.

Abstract: A printer-utilizing apparatus is disclosed herein, which decides automatically upon power throw whether the apparatus is in print mode or non-print mode and effects initializing of the printer and auto paper feed if the apparatus is in print mode, but does not conduct any printer operation such as initializing and paper feed, if the apparatus is in non-print mode. More particularly, the apparatus prevents unnecessary DC power consumption which otherwise would occur in a compact DC-powered printer apparatus and, when in print mode, conducts printer operations such as initializing of the printer and paper feed as well as notifying easily and clearly the operator that the apparatus has been turned on.

Abstract: Ribbon cartridges for typewriters or similar office machines must meet various design requirements, especially, must be easily exchangeable without soiling one's fingers, must be inexpensive to manufacture, and must dampen the noise in the printing area. To be avoided in addition is a soiling of the machine components when using the cartridge, through ribbon rub-off dropping through the holes in the bottom of the cartridge, and a smooth ribbon drive must be possible. These various problems are inventionally solved in that the cup-shaped base component of the cartridge casing features on the inside of the bottom protruding stiffening ribs which likewise serve to support the spools of the flangeless supply and take-up reels and/or prevent ribbon rub-off accruing in the cartridge casing from dropping out of the openings.
