Abstract
The disclosure relates to a film cassette drive mechanism in a dental radiographic apparatus for photographing the entire jaws which apparatus is used in tomography. The drive mechanism is of such construction that a film cassette disposed at one end of a rotary arm of the apparatus in an opposed relation with respect to an X-ray source disposed at the other end thereof is moved to feed a film necessary for tomography by driving a variable speed motor inside the cassette holder in synchronism with the speed of travel of the X-ray source responsive to the rotation of the rotary arm.
