Abstract
A ribbon cassette is selectively mounted in a printing device having an operating mechanism actuable between locked and released states. The ribbon cassette has a casing for accommodating therein a print ribbon that cooperates with the operating mechanism for printing characters. The cassette also includes an actuating mechanism for mechanically unlocking the operating mechanism to the released state when the casing is inserted into the printing device. In a preferred embodiment, the actuating mechanism is a projection on a wall of the casing that abuts a locking linkage within the printing device and moves the locking linkage to unlock the operating mechanism.
