PURPOSE:To minimize the number of ports provided between computers, by usng in common lines connected and inputted from the 1st computer for managing control to the 2nd computer for sequence for a plurality of control information transmisson. CONSTITUTION:Control instruction signals A, B transmitted between a microcomputer CPU1 for managing control which has a control function such as input fetch, discrimination and display for each key and detection switch of an operation unit, and microcomputer CPU2 for sequence which makes copy sequence control are constituted with three signal lines, and when a copy button is depressed, the CPU1 discriminates the copy-enabling condition, and a copy start singnal is transmitted to the CPU2 via lines X, Y when copying is possible. Further, the manual copy-possible state is transmitted on a line W. Jam correction signals V, T from the CPU2 to the CPU1, and a key input controlling signal S are transmitted via an instruction signal B line. |
