ABSTRACT:
A camera includes 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, which then converts this single serial data item thus output from the CPU into several PPM signals, and then the PPM signal conversion circuit section supplies the PPM signals to the magnetic head drive section.
