Abstract
A cassette for an X-ray film has a cover part, a body part, and means for connecting these parts in a closed position of the cassette. A magnetic plate is associated with one of the parts, whereas a counterplate is associated with the other part of the cassette. The counterplate is constituted by a material which is highly susceptible to a magnetic moment so that in the closed position of the cassette, the counterplate is attracted to the magnetic plate, whereby the coils are urged toward one another and reinforcing parts which surround the X-ray film are pressed to the latter.
