ABSTRACT:
A shutter curtain holder device in a camera comprises a shutter curtain folded back on itself at one end thereof, a stem disposed inside the folded portion of the shutter curtain, and a shutter beam surrounding the folded portion of the shutter curtain. The shutter beam has indented portions formed adjacent to the upper and lower edges thereof. The indented portions lie between the one end portion of the shutter curtain and the stem to render the spacing between the opposed portions of the shutter curtain at the folded end portion smaller than the transverse dimension of the stem.
