Abstract
Pulses are furnished which each indicate transport of a frame. The pulses are counted on a BCD counter. Selected outputs of the counter are connected to the inputs of coupling stages, each including a JK flip-flop. Each flip-flop changes state for a predetermined count on the counter. When each flip-flop changes state, a corresponding indicator lights up, thereby furnishing an indication to the photographer of how many frames have been transported.
