Abstract
A film-cassette holder for an X-ray apparatus is provided with means for removeably mounting the film-cassette in the holder in the correct position therein. The mounting means comprises spring catches which, when the cassette is inserted into the holder, automatically hold said cassette in its correct position in the holder, and which are arranged to permit the cassette to be removed from said holder with the use of only one hand. The cassette is arranged to be released by exerting pressure thereon perpendicularly to the insertion direction followed by a pulling movement in a direction opposite to the insertion direction. The cassette holder is provided with a grid pocket having means for removeably mounting a grid in its correct position in the pocket, spring catches being adapted automatically to mount the grid upon insertion of the grid into said pocket, and adapted to permit removal of the grid upon manipulation of said grid with one hand. Further, the cassette holder has a means for easy removeable mounting to a cassette holder arm.
