ABSTRACT:
A camera comprises a photographic information output circuit section, a CPU, a PPM signal conversion circuit section, a drive section for a plurality of magnetic heads, and a film feeding section. The CPU converts several parallel data items which are output from the photographic information output circuit section into a single serial data item and outputs it to the PPM signal conversion circuit section provided separately from the CPU. The PPM signal conversion circuit section converts this single serial data item into several PPM signals, and then supplies the PPM signals to the magnetic head drive section.
