Abstract
An endoscope has within the forward end section of a sheath a cassette loaded with a roll of film on which a body cavity of a human being is photographed. One end of a film take-up shaft on the cassette outwardly extends from a housing of the cassette and a pulley is fixed on the outer periphery of the extending end portion of the film take-up shaft. A string is wound around the pulley. The string is inserted through a single passage in the sheath and when the string is pulled by an operator at a control section the film is wound.
