摘要： An optical system driving device has a motor which rotates constantly in one direction for providing rotary driving power. A regular rotation electromagnetic clutch is connected to the rotating motor for transmitting driving power to the optical system for reciprocal movement of the optical system in one direction. A reverse electromagnetic clutch connected to the rotor motor transmits driving power to the optical system for reciprocal movement thereof in the opposite direction. A control circuit is provided which receives a pulse signal for controlling either the regular rotation or the reverse electromagnetic clutch at the start of the regular rotation electromagnetic clutch to gradually increase the effective driving power provided to the optical system to move the optical system at the start of movement.

摘要： A scanning system driving device capable of quickly and gently starting a scanning system. This driving device includes an electromagnetic clutch for forward rotation, for transmitting a driving force from a driving source to a moving body for an optical system, and a control circuit for controlling the application of a voltage to the electromagnetic clutch. The control circuit applies a rated voltage in the form of pulses to the electromagnetic clutch at intervals of such OFF time that the moving speed of the moving body is reduced once when the illumination and the scanning of a document by the moving body are started.

摘要： A system according to the invention has a plurality of sensors, a system control circuit and a plurality of actuators. State data, supplied from the sensors, is compared with characteristic data in the system control circuit. From this comparison, it is judged whether a fault has occurred depending upon whether the state data is relatively lower or higher. If a fault has occurred, fault inference fault is made on the basis of a comparison between qualitative data and fault diagnosis knowledge which are stored in the system control circuit. Then a judgement is made as to which of the elements in an image forming apparatus is abnormal. An actuator operating signal thereafter is generated as a result of this judgement.
