<p>An adapter (10) attachable to an image recording apparatus and operable for removably receiving therein a film cassette (18) assembly including a film unit to be exposed by the image recording apparatus. The adapter (10) includes a protective shield which normally protects an aperture of the image recording apparatus and which advances to an unblocking condition upon insertion of the film cassette (18) assembly so as to allow exposure of a film unit in the cassette (10) by the image recording apparatus. Upon removal of the film cassette (10) assembly, the protective shield advances to its blocking condition, whereby the image recording apparatus is protected. The adapter (10) also includes a mechanism for actuating the cassette (10) assembly during insertion for allowing exposure of a film unit when the shield is in the unblocking condition, and for terminating exposure upon removal of the film cassette. In one embodiment, there is provided a releasable locking device for releasably locking the transport assembly in the adapter. <MATH></p> |
