Abstract

PURPOSE: To surely prevent light leakage simply through application of simple additional fabrication by bending one of plural plades at one or more places and letting the blades make close contact with each other.
CONSTITUTION: Bends 1-7a thru 1-10a are formed to each of the other four blades 1-7 thru 1-10 except the blade 6 to be pivotally fitted to the position in close contact with an arm 32, out of 5 shutter blades. The bending angles of these bends vary with the thicknesses of the blanks of the blades and other conditions and the shapes of the respective bends are not always parallel to the straight line F. Application of bends to each of the other blades except the blade 6 in this way enables the gaps of the overlap portions of the respective blades to be eliminated and enables light leakage to be surely removed.
