Abstract: An ink ribbon feeding mechanism includes a cartridge mounting section, a first paying out rotor which is inserted into a first paying out core when a cartridge is being mounted in the cartridge mounting section, and a plurality of rotor side engaging portions which are provided on the first paying out rotor and which engage with a plurality of core side engaging portions when the first paying out rotor rotates. The rotor side engaging portion has an butting portion. When the cartridge is being mounted in the cartridge mounting section, the core side engaging portion butts against the butting portion, one or the other of the first paying out core and the first paying out rotor rotates, the rotor side engaging portion is inserted into the core side insertion recessed portion. A plurality of the butting portions are provided in positions different from each other in a cartridge mounting direction.
