IMAGE DISPLAYS

摘要

An image display consisting of an image grid (11) having a plurality of successive strips (68A-D) of each image disposed in parallel relationship to each other, and a masking grid (9) having a plurality of parallel window strips (64A) through which some image strips (68A-D) are visible whilst others are obscured and different images can be observed by relative movement between the grids (9, 11), the grids (9, 11) including grid alignment means (60A, 66) for use in aligning the image strips (68A-D) of the image grid (11) and the window strips (64A) of the masking grid (9) in substantially parallel relationship with each other, and further including grid registration means (60A, 61A-D, 62A-C) for bringing various of the images of the image grid (11) into registration with the window strips (64A) of the masking grid (9) when the grids (9, 11) are moved relative to each other after they have been brought into substantially parallel relationship with each other using the grid alignment means (60A, 66).
