In a slit shutter such as a focal plane shutter of the two blade type, the shutter blades and electrically operated magnetic drive means therefor are arranged on opposite sides of respective rotatable transmission means with respect to the axes thereof and are coupled therewith respectively to be movable in opposite directions relative to each other, whereby the possibility of a shock producing effect in the shutter is reduced at the time of actuation thereof.
