PURPOSE: To attain the reducing of the total cost in which a development expense is included. CONSTITUTION: Devices and respective members in a machine are classified every function, plural units are constituted by making respective functions one control unit and plural unit control means having unit controlling CPUs 152 having charges controlling units corresponding to respective plural units are respectively arranged in plural units. Moreover, EEPROMs 154 in which control programs for controlling the operations of own units are stored and ROMs 159 in which the control data of the whole of system are stored are arranged in specific unit control means among plural unit control means and when power is turned on, control timing data are transmitted from the specific unit control means to respective unit control mean and, then, respective unit control means perform the timing controls of own units based on received control timings. |
