In the film transport mechanism, the film strip is driven in the perforation plane from a drive shaft by means of at least one transport pin. The drive shaft has in the perforation plane a constant-diameter cam, to which the transport pin is coupled by a shuttle frame. To improve such film transport mechanism so as to reduce the noise generated by it in operation, the shuttle frame is additionally coupled to a rocking crank and slider linkage or to a slider, which is part of a slider crank mechanism, which has a drive shaft that is identical to the shaft for driving the transport shuttle.
