Abstract

PURPOSE:To simplify the circuit or signal line, etc. that concerns the transmission/ reception of signals between the circuits for which the speed of signal transmission is not so much important, by using the software in a highly efficient way. CONSTITUTION:A master computer 40 is connected with a slave computer 41 via signal lines 42 and 43. These lines 42 and 43 transmit the data given from a CPU40 and the strobe signal sent from the CPU40 respectively. The CPU40 controls via a signal line 44 the operations of the process units such as a high voltage primary transformer 45 which supplies the high voltage to a primary charger 22, a high voltage secondary transformer 26 which supplies the high voltage to a destaticizer 23, a lamp circuit 47 which supplies the lighting power supply to an illumination lamp 16, a development bias transformer 48 which applies the development bias to a developer 25, etc. The clock signal produced by a clock generator 55 which is provided at a CPU41 is used as the clock of the CPU41 as well as a clock source of D/A converters 50-53. Accordingly the number of component parts can be reduced for the circuit to increase the reliability.
