PURPOSE:To switch the density adjusting mode smoothly by operating a holding state changeover switch in the user side to indicate the holding state of a copying device. CONSTITUTION:When a main switch is turned on, a single chip microcomputer MPU23 sets the holding state and constitutes an input waiting loop. The density adjusting mode in this holding state can be selected by a holding state changeover switch SW1 provided on a switch unit 26. The MPU23 sets the automatic mode in the holding state if the switch SW1 is turned on, and the MPU23 sets the manual mode in the holding state if the switch SW1 is turned off. |
