Abstract

An image processing device for controlling data transfer includes an image scanner, an image printer, a facsimile control unit, bus lines for data transfer, a bidirectional parallel interface unit, and a main CPU in a housing. The device is connected to an external data processing device through the parallel interface unit. In addition to the functions which are obtained independent from the external data processing device, the image processing device realizes various kinds of functions by controlling the image scanner, the image printer facsimile control unit and the interface unit by the main CPU in response to commands from the data processing device. As a result, various kinds of image processing functions are carried out.
