Abstract
A triaxial focal plane shutter includes a second blind winding drum which is rotatably supported by a pair of support members disposed above and below it. A first blind winding shaft extends through the second blind winding drum and the pair of support members, and fixedly carries a pair of first blind winding pulleys on its upper and lower ends, thereby allowing an independent rotation of the second blind winding drum and the first blind winding pulleys.
