Abstract: 1,221,384. Ink ribbon mechanism. INTERNATIONAL BUSINESS MACHINES CORP. 8 July, 1969 [16 July, 1968], No. 34260/69. Addition to 1,183,172. Heading B6F. An ink ribbon cartridge 180 of the kind described and claimed in the parent Specification, including a slot 215 to receive a drive roller (40, Fig. 1) is modified in that the ribbon passes from a supply spool 184 to a take-up spool 199 around a guide 214 positioned at the end of the slot 215 furthest from the axis of rotation of the take-up spool. The drive roller (40) is driven by mechanism substantially as described in parent Specification, having two gear ratios selectable as a consequence of supplying the cartridge to the mechanism, the gear ratio being selectable according to the presence or absence of a member 220 1 limiting the depth of a recess 220 in the cartridge. The member 220 1 is intended to coact with :a gearratio selecting member (221, Fig. 4) of similar nature but modified construction with respect to the mechanism described in parent Specification. The cartridge further includes a slot 216 from which a stud (43, Fig. 5) may project, to indicate the amount of ribbon on the takeup spool 199. Knobs 190, 204, on the supply and take-up spools respectively, permit manual winding of the ribbon.
