A removable device adapted to cooperate with a conveyor system for the installation of an endless ribbon in the conveyor system, the removable device includes at least two support elements to support the endless ribbon, each support element being movable in rotation around a rotation axis and each support element having a convex portion to support a portion of the endless ribbon.

An ink ribbon cartridge includes a first spool, a first case covering the first spool, a second spool, a second case covering the second spool, a first rib provided at the first case, a second rib provided at the second case, an ink ribbon, a first protrusion, and a second protrusion. The first spool extends in a first direction and the second spool extends in a second direction. The first protrusion protrudes in the first direction from an end of the first case in the first direction. The second protrusion protrudes in the second direction from an end of the second case in the second direction. The first protrusion and the second protrusion are respectively fitted in a first hole and a second hole of a first frame of a printing device in a state where the ink ribbon cartridge is attached the printing device.

A described example includes a ribbon cartridge having a first spool housing to receive a first spool. The ribbon cartridge further having a second spool housing to receive a second spool. The ribbon cartridge further having at least one frame member extending between the first spool housing and the second spool housing and a spool lock, wherein the spool lock is configured to engage at least one of the first spool or the second spool in response to the ribbon cartridge not being received within a ribbon positioning assembly.
