PURPOSE:To constitute a n:n switch by arranging the (n)-number incident and projective rod lenses at right angles and then by arranging a group of the (nXn)- number composidte reflex mirrors movable vertically among them. CONSTITUTION:On the same plane, rod lenses 7 to 14 are arranged and lenses 7 and 8 are in parallel and confront to lenses 11 and 12. Lenses 9 and 10, in parallel, are prependicular to lenses 7 and 8 and confront to lenses 13 and 14. Lines connecting respective flanks of lenses 7 to 14 form a square of (a') in side length. In this square, four composite columnar reflex mirrors 17(1) to 17(4) are provided which can move vertically. This columnar reflex mirror 17 is a hexahedron of 3l in height with a square of a'/4 in side length at its one flank and composed of transparent cube 17a, reflection cube 17b and semitransparent cube 17c of l in length. In this constitution, respective reflex mirrors 17(1) to 17(4) are moved appropriately and vertically to provide a 2:2 switching function. |
