Abstract
An electrical drive which includes a motor for actuation of a film wind-up and shutter mechanism subsequent to exposure of a film frame and a mechanism for decoupling drive from the motor at the end of each wind-up and shutter charge action and also during this action if something occurs a fault preventing correct action of the film wind-up and shutter charge mechanism, whereby damage to the mechanism, the motor and film is prevented. The drive is correctly positioned with respect to a camera by a mechanism which also serves to provide electrical connection between a shutter control circuit and a drive control circuit, whereby the number of elements required to be precisely positioned with respect to the camera is less and manufacturing and assembly cost is reduced.
