A ribbon cartridge handling apparatus has a pair of pivotal couplings for three position handling of a ribbon cartridge in a typewriter. The apparatus includes a cartridge receiving receptacle pivotally supported on a first pivot coupling on a rocker. A second pivot coupling on a frame support structure in the typewriter pivotally supports the rocker. A first operative position of the apparatus locates the receptacle in an open position for allowing insertion of the ribbon cartridge into the typewriter. A second operative position of the apparatus locates the receptacle together with the ribbon cartridge in a non-printing position located near a print station in the typewriter. The receptacle is operatively pivoted about the first pivot coupling between the first and second operative positions. A third operative position of the apparatus locates the rocker together with the receptacle carrying the ribbon cartridge in a print position at the print station in the typewriter. The rocker is pivoted by a lift mechanism in the typewriter for oscillating the ribbon cartridge about the second pivot coupling between the second and third operative positions. A latch device is provided on the rocker to operate in conjunction with features on the ribbon cartridge for releasably holding the ribbon cartridge on the receptacle.

Ribbon Cartridge handling apparatus

A cartridge ribbon lift apparatus is provided in which a pivotally mounted cartridge, containing a ribbon, is pivoted upward to a printing position by a linkage which is operated by a solenoid. When the cartridge reaches the printing position a second linkage latches the cartridge in the printing position for repeat and burst speed printing and the cartridge remains in the printing position as long as the solenoid remains energized. While the cartridge is latched in the printing position the first linkage is restored to its initial operating position.
