摘要： A device for preventing contamination of a print sheet and the reduction in the effectiveness of a scorotron type charger by free toner and paper particles. The device includes a paper dust eliminator extending the length of a photosensitive member and a wiping mechanism at each end of the photosensitive member for removing free toner that has accumulated there. Further, a partition that separates the developing section from the charger can be provided to further reduce free toner from attaching to the charger.

摘要： A motor controller is made up of a power supply circuit rectifying an AC power supply for outputting desired DC voltages while, at the same time, improving the power factor of the AC power supply, and a motor drive circuit for driving a motor. The controller has a rectifier circuit for converting AC power to a DC voltage and a smoothing circuit, a converter circuit constituted of a chopper circuit for controlling the DC voltage by utilizing a switching operation and the energy storing effect of an inductance, a motor drive device made up of an inverter circuit connected to the output of the converter circuit to control a motor, a converter control circuit for controlling the switching operation of the chopper circuit, an inverter control circuit for controlling the switching operation of the inverter circuit thereby driving the motor, a speed detector circuit for detecting a position of the rotor of the motor for calculating the speed of the motor, a speed control circuit receiving the calculated speed value and a speed command value for controlling the motor speed through the inverter circuit, and a DC voltage control circuit receiving the output signal of the speed control circuit for controlling the DC voltage through the converter control circuit in accordance with the output signal. The DC voltage control circuit, when the output of the speed control circuit reaches a predetermined value, outputs a signal to cause the DC voltage to increase or decrease to the converter control circuit. The output of the speed control circuit is a duty ratio signal or a speed deviation signal representing a deviation of the calculated speed value from the speed command value.

摘要： An ink jet printer includes a print head having ink nozzles, which is movable in a direction across the feeding path. A supply mechanism is provided at one side of the feeding path, which supplies ink to the print head located in the ink supply station. A maintenance mechanism is provided at the other side of the feeding path, which operates a predetermined operation. The ink jet printer is further provided with a first clutch which transmits the rotation of the actuator to the supply mechanism only when the print head is located in the above-mentioned one side, and a second clutch which transmits the rotation of the actuator to the maintenance mechanism only when the print head is located in the above-mentioned the other side. With this, the supply mechanism and the maintenance mechanism are actuated by a common actuator.
