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 fixing unit includes a heat roller accommodating a heater and a press roller movable between an operating position in which the recording sheet is nipped by the rollers and a retracted position. A driven gear is provided to one axial end of heat roller, which engages a rotating mechanism for rotating the heat roller. An opening/closing mechanism is arranged to move a first axial end (at the same side as the driven gear of the heat roller) of said press roller to said operating position before moving a second axial end of the press roller to the operating position.

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： An ozone-exhaust duct is incorporated in an electrophotographic printer to exhaust air, containing ozone and dust articles, and an exit structure of the duct is associated with an ozone-filter. In the exit-structure, a dust trapper is provided under an exit end portion of the duct near the ozone-filter to define a dust-trapping chamber such that a cross-sectional area of the exit end portion of the duct is increased in comparison with a cross-sectional area of a remaining portion of the duct, whereby a velocity of the air, introduced from the remaining portion of the duct into the exit end portion thereof, slows down, due to the existence of the ozone-filter and the increased cross-sectional area of the exit end portion of the duct, resulting in trapping of a part of the dust particles, contained in the introduced air, in the dust-trapping chamber of the dust trapper due to gravity.
摘要翻译：臭氧排放管道结合在电子照相打印机中以排出含有臭氧和灰尘物品的空气，并且管道的出口结构与臭氧过滤器相关联。在出口结构中，在臭氧过滤器附近的管道的出口端部下方设置集尘器，以限定吸尘室，使得管道的出口端部分的横截面积相应增加具有管道的剩余部分的横截面积，由此由于臭氧过滤器的存在而导致从管道的剩余部分引入其出口端部分的空气的速度减慢，并且导致管道的出口端部的横截面面积增加，导致包含在引入空气中的灰尘颗粒的一部分由于重力而被捕集在集尘器的除尘室内。
