摘要： A fixing unit includes a heat roller accommodating a heater and a press roller movable toward and away from the heat roller. Both shaft members of the heat roller are supported by two receiving members, with a clearance provided between each shaft member and respective receiving member. A driven gear is provided to one of the shaft member, which engages a rotating mechanism for rotating the heat roller. The fixing unit further includes a biasing member which biases the other shaft of the heat roller away from the press roller within the clearance, in such a manner that the heat roller and the press roller become parallel when the above-described one shaft member is urged away from the press roller due to the meshing engagement of the driven gear and the rotating mechanism.

摘要： A sheet feed mechanism utilizing a continuous form sheet, with a plurality of equally spaced sprocket holes formed on both side edges thereof in the direction along a straight sheet feed path, is fed between a photoconductive member and transfer member. Each side of the sheet feed mechanism includes an endless tractor belt looped between two feed rollers disposed upstream and downstream of the transfer member, respectively. In one aspect, engaging pins are provided on the circumferential surface of the feed rollers and engaging holes on the tractor belt spaced at the same interval as the holes of the continuous form sheet, to feed the sheet by engagement of the engaging pins and the sprocket holes through the engaging holes. In another aspect, the endless belt is provided with the engaging pins and a regulation member for moving the tractor belt such that a portion of its upper part is separated from the photoconductive member.

摘要： A fixing unit, used for fixing images on a recording sheet, includes a heat roller accommodating a heater, and a press roller movable between a retracted position and an operating position. The heat roller is rotated by a driving mechanism. A moving mechanism opens and closes a gap between the press roller and the heat roller by moving the press roller between the retracted position and the operating position. An assist gear rotates the press roller in a predetermined direction when the opening/closing mechanism moves the press roller toward the operating position.

摘要： A driving power control device for a hybrid vehicle controls the engagement state of a lockup clutch so that high efficiency in regeneration is obtainable. The driving power control device for a hybrid vehicle includes an engine and a motor-generator as power sources, an automatic transmission disposed between the power sources and driving wheels with an intervening torque converter having a lockup clutch, and an ECU for controlling selection of the power sources and for controlling a slip ratio of the torque converter. In this control device, a target slip ratio of the torque converter, which corresponds to a target amount of regeneration that is retrieved using regeneration amount determining factors, is obtained by executing a feedforward control operation using friction torque determining factors, and the slip ratio is controlled in a feedback manner based on the difference between the target slip ratio and the actual slip ratio.

摘要： A multi-beam scanning optical system includes a plurality of light sources, a deflecting unit which deflects a plurality of laser beams emitted from the light sources, and a scanning optical unit which focuses the laser beams deflected by the deflecting unit onto the surface of a photosensitive member. The scanning optical unit is set such that lateral chromatic aberration is overcorrected. In addition, among angles formed between each laser beam incident on the surface of the photosensitive member and the normal at the surface of the photosensitive member in a sub-scanning direction, the oscillation wavelength of the light source that emits a laser beam forming the minimum angle is set to a value smaller than the oscillation wavelength of the light source that emits a laser beam forming the maximum angle.

摘要： The tractor-feed unit has a pair of first and a pair of second rollers rotatably supported by frame members. A pair of endless tractor belts are wound around the first and second pair of rollers. The tractor belt has protrusions, with which sprocket holes formed in a continuous sheet are engaged. A central portion of each of the frame members is bent to form a guide member, which is engaged with an upper and peripheral edge of a tractor belt, so that a tractor belt is deflected downward. Thus, the protrusions are separated from the sprocket holes to a position, corresponding to a guide member, below the continuous sheet.
