An electromagnetic drive device is described for use in a camera to electromagnetically drive the diaphragm or shutter blades. A conductive coil pattern is positioned on the opposite sides of a rotor for the shutter drive. The shutter blades, which are driven by the rotor, are made of a synthetic resin. In order to connect the rotor to the shutter blades, electrically conductive drive pins are used to electrically couple the coil pattern on one side of the above-described rotor to the pattern on the opposite rotor side. The axle of the drive pin, moreover, is fixed in a penetration hole in the rotor.
