ABSTRACT:
A photographing device is provided with a pair of support members positioned in mutually opposed manner across a film, a sensitivity increasing screen mounted on at least one of the paired support members, a sealing member for hermetically sealing a space containing the film and the sensitivity increasing screen, a vacuum pump for reducing the pressure in the sealed space to maintain the film and the sensitivity increasing screen in mutual close contact, and a support member for maintaining the film in a predetermined position between the support member in the sealed space. Thus the sensitizing screen can be securely contacted with the film, and errors in operation are reduced even when the photographing operation is conducted with the film in vertical or inclined position.
