Abstract
Abstract A typewriter employs two separate ribbons held in two separate cartridges respectively. A mechanism is employed for moving either ribbon into operating position. For example, in one form of the invention a transport carries the two cartridges and may be moved to the left and right respectively to bring either ribbon into operating position. In a modified form of the invention, two backspace keys on the keyboard move the two cartridges into their respective operating positions. In another modified form, the ribbon of the first cartridge remains in operating position and the ribbon of the second cartridge may be moved into position behind the ribbon of the first cartridge so that printing is accomplished by the second cartridge. In still another modified form, the two cartridges are not on a common transport but are selectively movable into operating position and when either is moved into operating position the other is moved out of such position.
