Abstract
The program control device contains an electronic read-only memory for each photographic program, whose input is connected to a resettable pulse counter which is actuated step-by-step via a clock pulse generator. Each read-only memory delivers program signals predetermined by its program that correspond to the output signals of the pulse counter and the outputs of all read-only memories are connected to the components they control via a program selector circuit. For a free program, a freely programmable memory is provided, whose content can be transmitted into an unprogrammed program module.
