Abstract
A cylindrical container for containing a film cassette includes a bottom surface having a pair of radially extending rib members for engaging with a centering apparatus. According to the invention, the radially extending members are diametrically opposed to one another to reduce axial misalignment of the container when it is being centered on the centering apparatus. The centering apparatus includes a pair of restricting elements which engage the rib members when the container is mounted to the apparatus and which more accurately locate the container to a predetermined radial location due to the engagement of each restricting element with each of the rib members.
