Abstract
PURPOSE:To enable the copying machine to be controlled surely and with good efficiency by letting one of the input and output ports of mutual microcomputers be a control line and using besides this one of input and output ports for transfer of information. CONSTITUTION:Sequence controlling and various check functions of copying processes are divided to two blocks and are shared by two microcomputers, 6, 7 by which they are processed resprctively independently. At the time of performing the transfer of information between the computers 6, 7, the input and output ports 8 and 9 are used as a control line and are recognized by performing bit test, after which the transfer of information is performed by the output instruction and input instruction using the input and output ports 10, 11 being one of other input and output ports. In this way, the two microcomputers are able to progress sequence while maintaining the mutual communication.
