ABSTRACT:
An ink ribbon cassette for supplying ink from an ink-impregnated material to an ink ribbon in which the ink-impregnated material is loaded directly in the cassette body without an ink tank, and in which leakage of ink caused, for instance, by vibration or sudden temperature change, is positively prevented. The ribbon cassette includes a cassette body having a container formed as an integral part thereof and a cover fixedly secured to the cassette body. The container accommodating the ink-impregnated material is formed in such a manner that a space is formed between the ink-impregnated material and the cover, and an ink pool having a capillary action is formed on the inner surface of an outer peripheral wall defining the container.
