Apparatus for use in taking chest or other X-rays, including a dispenser for the dispensing of one film sheet at a time and a film holder which receives the film sheet and holds it tightly between intensifier screens and which then releases the film sheet for developing. The film sheet and intensifier screens are sandwiched between a backing plate and a plastic sheet. An elongated vertical pressing device can be moved against the middle of the backing plate to deflect it into a curve and thereby cause the film sheet to be held tightly against the intensifier screens.
