一种可与计算机显示器垂直放置的副本架，以减少视觉疲劳和头部转动。副本架托盘的后边缘部分连接到紧固件上，紧固件安装在侧壁的细长槽中，用于在用于存储副本的副本架内的第一位置和用于显示副本的副本架托盘从副本架向前延伸的第二位置之间移动副本架托盘。所述插槽被升高到桌面上方，使得所述拷贝架托盘在第二位置时以舒适的预定角度（优选约22度）向所述桌面倾斜，并将所述监视器屏幕升高到舒适的观看高度。根据一个实施例，使副本支架被接收或放置在显示器支架的架子上以达到预定的角度。或者，副本架的侧壁延伸到达到预定角度的高度。
A copy holder which may be placed in-line vertically with a computer monitor to reduce visual fatigue and head turning. A rear edge portion of the copy holder tray is attached to fasteners which are mounted in elongate slots in the side walls for movement of the copy holder tray between a first position within the copy holder for storage of copy and a second position wherein the copy holder tray extends forwardly from the copy holder for displaying copy. The slots are elevated above a desktop so that the copy holder tray is inclined to the desktop at a comfortable predetermined angle, preferably about 22 degrees, when in the second position, with the monitor screen elevated to a comfortable viewing height. In accordance with one embodiment, the copy holder is caused to be received or rest on the shelf of a monitor stand to achieve the predetermined angle. Alternatively, the side walls of the copy holder extend to a height which achieves the predetermined angle.
