A device for controlling the optical path of a cinematograph projector includes a shutter connected to an electromagnet through a transmission which transforms the motion initiated by the magnet into a motion which, plotted as a function of time, approximately substantially to a half period sine curve between a negative and a positive peak. As shown, the shutter comprises parts 15 and 16 mounted on parallel shafts 13 and 14 coupled by arms 27, 28 to rods 25 and 26 which are pivoted at opposite ends respectively of a member 22, fixed to a shaft 20 having a pinion 21 in mesh with a pinion 19 which is rotated when a rotary electromagnet 18 is energized e.g. by means of a change-over switch in a second projector. The two rods 25 and 26 lie in a straight line in each terminal position of the rotatable member 22 which is rotated through 180 degrees for each stroke of the electromagnet armature so that the displacement of the shutter parts varies substantially sinusoidally during the time taken to reach the fully open position. A pin 29 on the pinion 19 is coupled by a spring 13 to a lever 31 which rests against a screw 33 for adjusting the tension in spring 30. This spring 30 is tensioned during the opening movement of the shutter, and, on de-energization of the electromagnet 18, serves to rotate the pinion 19 and so close the shutter. During the opening movement of the shutter, the rod 35 connected to the shaft 13 raises a lever 36 to close switches 40 to energize other parts of the projector, these switches being opened during closure of the shutter.
