摘要:
The apparatus includes: an extension devices interface to which a plurality of extension devices are connectable; a connector to which predetermined IC cards are detachably applied; a rewritable program memory for a main body to store a control program of the main body; a CPU for controlling the respective devices and for processing input image data on the basis of the control program of the main body; and an image control unit to achieve control based on control of the CPU for recording and outputting the image data which have been processed and outputting them to any one of the extension devices. The extension devices interface includes control data lines for transferring and receiving control data with the extension devices, and down load exclusive lines for down loading a control program of the extension device of the extension devices.
