ABSTRACT:
In a recording device, such as a facsimile machine, has a lower cover and an upper cover pivotable with respect to the lower cover for opening and closing, a photosensitive drum mounted to the upper cover, and a paper guide assembly through which recording paper is guided, support rollers rotatably mounted on the paper guide assembly such that they are engageable with the ends of the photosensitive drum, a transfer charger is movable together with the paper guide assembly, and a spring resiliently presses the transfer charger toward the photosensitive drum. When the upper cover is closed, the photosensitive drum is caused to abut on the support rollers, and the relative position between the paper guide assembly, the photosensitive drum, and the transfer charger is thereby maintained constant.
