Abstract
A manually operated moveable display device for displaying a plurality of images comprising an image member with an inage panel slidably retained adjacent to a shutter panel of a shutter member. A plurality of coded images are disposed on the image panel, a plurality of shutter elements are disposed on the shutter panel in alignment with the coded images, and a plurality of viewing elements are interposed between the plurality of shutter elements. The device maintains the first edge of the image panel and the first edge of the shutter panel in a substantially parallel relationship, the second edge of the image panel and the second edge of the shutter panel in a substantially parallel relationship, the image panel of the image member and the shutter panel of the shutter member in a bowed condition, and the image panel and the shutter panel of the shutter member in contact. The moveable display device may comprise most preferably a first bowed sleeve slidably surrounded in close frictional contact by a second bowed sleeve with coded images disposed on a front panel of the first bowed sleeve and shutter elements and viewing elements disposed on a front panel of the second bowed sleeve. The first and second bowed sleeves may be formed for precise registration and size by use of registration points disposed adjacent to the corners of first and second flexible sheets from which the first and second bowed sleeves are formed.
