An improved multi-image film cassette holder especially adapted to produce hard copy images from the oscilloscope display of radio-isotropic, ultrasonic, thermographic or computerized axial tomographic devices which utilize an oscilloscope to produce soft images. The film cassette holder includes guides at 90 DEG to each other and suitable masks or curtains so that predetermined portions of the film within the cassette can be exposed one at a time by manually moving the cassette to predetermined positions with respect to an imaging system such as an oscilloscope camera. The film cassette holder can be adapted to fit a wide variety of such cameras while using a conventional film cassette.
