ABSTRACT:
A control system for controlling a recording apparatus having a plurality of microcomputers, each microcomputer being formed in a single package. Each package includes an optical interface having a light-emitting device and a light-receiving device, an optical fiber cable connector attached to the package of the microcomputer, and an internal light transmission line for connecting the optical fiber cable connector to the optical interface inside the microcomputer package. Optical fiber cables for data communication are connected to the respective optical fiber cable connectors of the plurality of the microcomputers. In the control system, data vulnerable to electric noises are input through the optical interface.
