    • In an image reading apparatus, an image is illuminated to be guided as a light beam to a photosensitive drum through an image forming lens. Light amount correcting members are attached to a movable member movably attached relatively to the image forming lens. The movable member moves in the optical axis direction in accordance with movement of the image forming lens, and one of the light amount correcting members farther from the image forming lens is caused to face a corresponding surface of the image forming lens so as to intercept a part of the light beam from the image in association with the movement of the movable member. The other of the light amount correcting members closer to the image forming lens is caused to retract from a corresponding surface of the image forming lens in association with the movement of the movable member.
    • 在图像读取装置中,通过图像形成透镜照射图像作为光束被引导到感光鼓。 光量校正构件附接到可移动地相对于成像透镜安装的可动构件。 可移动构件根据成像透镜的移动沿光轴方向移动,并且使距离图像形成透镜更远的光量校正构件中的一个面对图像形成透镜的相应表面,以截取 与来自可动构件的移动相关联的来自图像的光束的一部分。 使得靠近图像形成透镜的光量校正构件中的另一个与可动构件的移动相关联地从成像透镜的相应表面缩回。

    • An apparatus has a first conveyor for conveying a recording medium into an image forming unit which forms an image on a recording medium, a second conveyor for re-conveying the recording medium having an image formed thereon by the image forming unit to the second conveyor, and a curl straightener, formed by a plurality of rollers forming a bent path within the second conveyor, for straightening the curl on the recording medium. The conveyance speed of the second conveyor is switchable between a first speed equal to the conveyance speed of the first conveyor and a second speed which is greater than the first speed. The first speed is the speed of the recording medium until at least a predetermined length of the recording medium passes the curl straightener, and the second speed is the speed of the recording medium after passage therethrough. When image formation is performed in either two-side image forming mode of multiplex mode, it is possible to increase productivity during image formation by allowing the recording medium with the image to take a sufficient time to pass the curl straightener and thereafter re-conveying the recording medium at a higher speed to the image forming section.
    • 一种装置具有用于将记录介质输送到在记录介质上形成图像的图像形成单元的第一传送器,用于将具有通过图像形成单元在其上形成的图像的记录介质重新传送到第二传送器的第二传送器, 以及由多个辊形成的卷曲矫直机,所述多个辊在所述第二输送机内形成弯曲路径,以矫正所述记录介质上的卷曲。 第二输送机的输送速度可在与第一输送机的输送速度相等的第一速度和大于第一速度的第二速度之间切换。 第一速度是记录介质的速度,直到记录介质的至少预定长度通过卷曲矫直机,第二速度是记录介质通过之后的速度。 当以多重模式的双面图像形成模式进行图像形成时,可以通过使图像的记录介质花费足够的时间通过卷曲矫直机,并且之后重新输送 记录介质以更高的速度传送到图像形成部分。

    • An image forming apparatus includes an image reader for reading information about an image on a document, a sheet support disposed below the image reader and arranged for supporting sheets thereon, and an image forming unit disposed between the image reader and the sheet support. A body of the image forming apparatus has at least one of the image reader, the sheet support and the image forming unit, and provides a sheet discharging space into which a sheet having an image formed thereon by the image forming unit is discharged, where the image reader, the sheet support, and the image forming unit are arranged around the sheet discharging space. The image forming apparatus further includes an opening unit for exposing the image forming unit to the exterior of the image forming apparatus through the sheet discharging space.
    • 图像形成装置包括用于读取关于文件上的图像的信息的图像读取器,设置在图像读取器下方并被布置成用于在其上支撑片材的片材载体,以及设置在图像读取器和片材载体之间的图像形成单元。 图像形成装置的主体具有图像读取器,片材支撑件和图像形成单元中的至少一个,并且提供排出由图像形成单元形成在其上的图像的片材排出的片材排出空间, 图像读取器,片材支撑件和图像形成单元布置在片材排出空间周围。 图像形成装置还包括用于通过片材排出空间将图像形成单元暴露于图像形成装置的外部的打开单元。
