Abstract
Abstract A printer for use with a data processor and a ribbon cartridge for use in the same are disclosed. The cartridge has at least two separate ribbon supplies which may differ in the type of ink on the ribbon (MICR vs. ordinary) and/or in color of ink or otherwise. A mechanism moves the cartridge along a straight line path to index selectively an active portion of each of the ribbons to a position aligned between a printhead and a platen for printing through the selected ribbon. A ribbon drive mechanism drives at least one of the ribbon supplies only when that ribbon supply has been selectively indexed to be printed through. In one embodiment a Magnetic Ink Character Recognition ribbon supply is driven between take-up and supply reels only when it is indexed for printing, while a multi-strike ribbon with ordinary ink is driven continuously. In another embodiment only one of two or more ribbon supplies is driven at one time. In both embodiments the straight line movement of the cartridge between indexed positions engages and disengages the drive to the various ribbon supplies by movement of the cartridge along the axis of a ribbon drive shaft.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
270 words
A cartridge and drive assembly for use with a printer having a frame and an axially reciprocatable print head, the improvement comprising ribbon cartridge means for containing a plurality of bands of inked ribbon, means for supporting a portion of each of said bands of inked ribbon in a common plane, and means for shifting said cartridge means along a straight line path between a first position in which one of said bands of inked ribbon is aligned for printing and a second position in which another of said bands of inked ribbon is aligned for printing, carriage means for supporting said ribbon cartridge means, said carriage means and ribbon cartridge means being movable with said print head, and said means for shifting comprising a shaft fixed against axial movement, rotatably mounted in fixed position relative to said frame, and extending axially parallel to the axis of reciprocation of said print head, motive means for producing a mechanical output to effect shifting, said motive means being mounted fixed to said frame against reciprocation with said carriage means and being coupled to said shaft to rotate said shaft to effect shifting, a crank arm axially slidable along said shaft and fixed against rotation relative to said shaft, and means for connecting the distal end portion of said crank arm with said ribbon cartridge means to effect movement of said ribbon cartridge means along the straight line path upon rotation of said shaft, and said carriage means including means for positioning the axis of said shaft with respect to said carriage and for positioning said crank arm with respect to said carriage.

Claim 6
Dependent Claim
22 words
The cartridge and drive assembly of claim 1 wherein said ribbon cartridge means includes means for containing a plurality of separate ribbons.
Claim 7
Dependent Claim
21 words
The cartridge and drive assembly of claim 5 further including means movable with said carriage means for selectively driving said ribbons.
Claim 8
Dependent Claim
81 words
The cartridge and drive assembly of claim 6, wherein said means for selectively driving includes a drive wheel associated with each of said ribbons, a motor driven shaft, said motor driven shaft having torque transmitting surface means for engaged surfaces on one of said drive wheels when said cartridge means is in selcted position along said straight line path and wherein said motor driven shaft is axially movable and biased in at least one axial direction to a predetermined axial position.
Claim 9
Dependent Claim
43 words
The cartridge and drive assembly of claim 7 wherein said means for selectively driving one of said ribbons includes motor means fixed with respect to said straight line movement of said cartridge means between said operating positions for driving said motor drive shaft.
Claim 10
Dependent Claim
18 words
The cartridge and drive assembly of claim 7 wherein one of said ribbons is inked with MICR ink.
