Abstract (en)

[origin: EP0234254A1] The inked ribbon cartridge (1) is featured by a ribbon detecting mechanism (25-28) which engages an outer circumferential surface of a wound inked ribbon (4b) around a take-up spool (6) and actuates a ribbon end detecting switch (SW) when a radius of the wound inked ribbon is greater than a predetermined value (Rr). This cartridge detects a ribbon end of an inked ribbon with high reliability and feeds an inked ribbon without damaging it.
