Multi-display apparatus

Abstract

A multi-display apparatus that makes it possible to form a plurality of images on a screen unit 4 and display a single picture image, by carrying a plurality of projection units 3 on an engine unit 2 of an apparatus main body. The projection unit 3 has a projector 28 and a plurality of mirrors 22, 23, and 24 for bending projected light from the projector 28 mounted on a same base plate 25. The engine unit 2 is configured in a shelved structure wherein a plurality of projection units 3 are deployed vertically and horizontally. The positions between the optical systems on the base plate 25 of the projection unit 3 are adjusted beforehand. After adjusting a projected image by the projection unit 3 itself, the base plate 25 of the projection unit 3 is slidden over rail members in the engine unit 2 and secured. The positioning of the projection unit 3 with respect to the engine unit 2 is done with the base plate 25 of the projection unit 3, and therefore fewer positional adjustments in the optical systems will suffice after placing the projection unit 3 in the engine unit 2.
