A copying paper feed device for an electrostatic copier. A copying paper cassette receiving section is adapted to receive a copying paper cassette having a box-like case with a bottom plate the front end of which is biased upwardly by a spring. Within the cassette receiving section, a feed roller is mounted on a rotatable shaft that is adapted to be connected to a drive source. When the copying paper cassette is properly loaded into the cassette receiving section, the front end of the uppermost sheet of copying paper contacts the feed roller. A clutch in its operating condition links the feed roller with the drive source and in its non-operating condition permits the feed roller to freely rotate.

An optical unit may include an image pick-up device, a lens unit and a holding member. The image pick-up device may convert a reflected light reflected from an original document to an electric signal, after the light is irradiated on the original document from a light source. The lens unit may image the reflected light on the image pick-up device. The holding member may hold the image pick-up device and lenses. The direction of a fluctuation of a focal length of the lens unit caused by heat and a direction of the fluctuation of a distance between the image pick-up device and the lens unit caused by heat may agree with each other.

To provide an engine exhaust gas treatment system that can efficiently reduce and remove NOx using easy-to-handle urea as the reducing agent, regardless of the engine operating conditions. An exhaust gas denitration system in which an exhaust gas is introduced into the denitration catalyst reactor 5 provided in the exhaust gas flue 3, where NOx is reduced and removed in the presence of the denitration catalyst, wherein a diversion means provided in the exhaust gas flue 3 introduces part or all of the exhaust gas into a urea solution injection evaporator having a heating means by the heater 30, and the heat from the exhaust gas and the heat from the heater serve to generate ammonia that is then circled and mixed with the exhaust gas and introduced into the denitration catalyst reactor 4.

An image forming machine having a reversing transport path in which a transport direction of a sheet introduced from an image forming transport path is reversed, a returning path in which the sheet reversely transported from the reversing transport path is returned below the image forming transport path with the directions of the face and back of the sheet being unchanged, and an inverting transport path in which the sheet from the returning path is turned upside down and readmitted into an upstream portion of the image forming transport path. A finisher including a sheet receiving stand placed below the returning path is provided, and at least one send-in unit for selectively sending in different length sheets onto the sheet receiving stand is disposed in the returning path.

A switchback device has an inverting tray for temporarily holding a sheet guided inside the switchback device thereon; a guide unit for guiding the sheet in pressing contact with the inverting tray when the sheet exits the switchback device in an exiting direction on the inverting tray, the exiting direction opposite to an entering direction of the sheet on the inverting tray; a guide switching unit for selectively changing the guide unit to a sheet guide allow state to allow the sheet to enter in the entering direction on the inverting tray and a sheet pressing state to make the sheet in pressing contact with the inverting; and a sheet transporting unit for transporting the sheet out of the switchback device in the exiting direction on the inverting tray.
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:
An electrostatic copying apparatus equipped with a first and second supporting frames connected to each other for relative pivotal movement between an open position and a closed position. The rotatable drum and the developing device are mounted on a first unit frame, while the drum cleaning device and the charging corona discharge device are mounted on a second unit frame. The first unit frame and the second unit frame are each mounted on the upper supporting frame with the cleaning device, the charging corona discharge device and the developing device mounted around the drum in sequence in the drum rotating direction. The first unit frame and the second unit frame are detachably mounted on the upper supporting frame and thus can be readily accessed for maintenance.

An electrostatic copying apparatus equipped with a first and second supporting frames connected to each other for relative pivotal movement between an open position and a closed position. The first supporting frame has provided therein a rotatably mounted interlocking input gear and a first power transmission system drivingly connected to the interlocking input gear. The second supporting frame has provided therein a drive source, a second power transmission system drivingly connected to the drive source and a rotatably mounted interlocking output gear drivingly connected to the drive source. A pivot member mounted pivotally about the axis of rotation of the interlocking input gear or the interlocking output gear and elastically held at a predetermined angular position by a spring means is provided in the first or second supporting frame. An interlocking linking gear is rotatably mounted on the pivot member. The interlocking linking gear is drivingly connected to the interlocking input gear or the interlocking output gear rotatable over a slight angular range. When the first and second supporting frames are relatively pivoted and brought to the closed position, the interlocking linking gear comes into engagement with the interlocking output or input gear.
