PURPOSE:To facilitate the input action of a stereoscopic picture data from a TV camera or the like or picture data from an original reader by selecting an analogue signal or a digital signal in accordance with a signal handled with a picture printing means. CONSTITUTION:A video signal from the TV camera 2 is converted by an A/D converter in a reader/printer interface part (RPIP) 17 and is written into an image memory 16. On the other hand, picture data from a reader 1 is written into the memory 16 through the RPIP 17. In the case of outputting the picture from a document printer 3, picture data stored in the memory 16 is supplied to the document printer 3 through the RPIP 17. In the case of outputting the picture from a video printer 4 on the other hand, picture data stored in the memory 16 is converted by a D/A converter in the RPIP 17. The analogue video signal is supplied to the video printer 4.
