Abstract
Abstract A number of format films carrying fixed information to be recorded together with computer output information given by a magnetic tape are vertically stacked in a cassette. The cassette is supported on a vertically movable cassette support. At a predetermined level which is of the same level as a projection station where the format film is brought and the image of the film is projected there is provided a format film gripping device. The format film gripping device has a fixed arm and a swingable arm which are opened at the cassette and closed to grip one of the format films in the cassette when the gripping device is driven to take out one of the format films from the cassette and brings the taken out format film to the projection station. The vertically movable cassette support is moved up and down stepwisely to selectively bring one of the format films to be projected to the predetermined level where the format film is taken out of the cassette and brought to the projection station.
